How to Cook Lentils: 20 Recipes + Complete Guide (Red, Green, Brown & French)

Red lentils collapse into dal, French lentils hold for salads: the cook times, ratios and 20 recipes that match each type to the right dish.

To cook lentils, rinse 1 cup of dry lentils, add them to a pot with 3 cups of water or broth, bring to a boil, then simmer gently until tender. Red split lentils take 10–20 minutes and fall apart. Brown, green and French lentils take 20–30 minutes and keep their shape. There's no need to soak them. One cup dry makes about 2½ cups cooked.

How to Cook Lentils: The Short Answer

Here's the whole method in one place, then the details by type.

1. Sort and rinse. Tip the lentils into a fine-mesh strainer, pick out any small stones, and rinse under cold water for about 30 seconds. A cheap set like the Cuisinart 3-piece mesh strainers is small enough to hold red lentils, which slip straight through a colander.

2. Use a 3:1 ratio. Put 3 cups of liquid in the pot for every 1 cup of dry lentils. Both Harvard's Nutrition Source and the Canadian growers' guide at Lentils.org use that ratio.

3. Boil, then simmer. Bring the pot to a boil, turn it down to a gentle simmer, and cover partway. A hard boil splits the skins and turns whole lentils ragged.

4. Taste early. Start checking red lentils at 10 minutes and whole lentils at 18. They're done when they're tender with no chalky center.

5. Season at the end. Add salt once they're tender, and hold acids like vinegar, lemon or tomato until then too (the "Method 1" section explains why).

6. Drain or don't. For salads, drain off the extra liquid. For dal and soup, keep it, because it's part of the dish.

Lentils are the one common pulse you can cook from dry on a weeknight with no planning. Lentils.org and Harvard's guide both say soaking isn't needed. That speed is also why, as soup season starts in mid-September, a pot of lentils is the cheapest cozy dinner you can make.

The Four Lentils You'll Actually Buy: Red, Green, Brown, French

A grocery store usually stocks four kinds, and the type matters more than any other choice. Harvard's guide explains the key split: whole lentils with the husk on keep their shape, and split lentils with the husk off break down into a purée. Pick the type for the texture you want, then pick the recipe.

Red lentils are split lentils with the husk removed. They cook fastest and dissolve completely. That's exactly what you want in Indian dal and Turkish red lentil soup, and exactly what you don't want in a salad.

Brown lentils are the everyday supermarket bag and the cheapest option. According to Wikipedia's lentil entry, the large brown types rarely hold their shape well, so they're best in soups and stews where a little breakdown adds body.

Green lentils are a step firmer. In most recipes you can swap brown and green lentils one for one and just check tenderness a few minutes later.

French green lentils are the salad lentil. The name "Lentille verte du Puy" is a Protected Designation of Origin in the EU and only covers lentils grown around Le Puy in the Auvergne. In the US, the same variety grown elsewhere is sold as "French green lentils." Their thick skins keep them separate even after half an hour of simmering.

Methods Table: Stovetop, Instant Pot, and Slow Cooker Times by Type

All times assume 1 cup of dry, rinsed lentils. They're starting points: lentil age and water hardness can add 5–10 minutes, so taste before you trust the clock.

The pressure-cooker and slow-cooker figures match the tested recipes linked below. The Instant Pot Spiced Indian Lentil Dal runs red lentils for 8 minutes with a 10-minute natural release. The Instant Pot Lentil and Vegetable Stew runs green lentils for 10. The Slow Cooker Moroccan-Spiced Lentil and Carrot Stew cooks brown lentils for 6–7 hours on low.

Method 1: Stovetop Simmer — The Default

The stovetop is the most controllable method, and it's the only one where you can taste as you go. Use a heavy pot so the bottom doesn't scorch while the lentils thicken. A 6-quart enameled Dutch oven like the Amazon Basics enameled cast iron Dutch oven holds a double batch of soup and costs about $42 as of September 2026. Any heavy pot from our cookware section will do.

For whole lentils (brown, green, French): Build flavor first. Sweat a diced onion, carrot and a couple of garlic cloves in olive oil for 5–6 minutes. Add the lentils, a bay leaf and a thyme sprig, then 3 cups of broth. Simmer partly covered for 25 minutes and start tasting. The Braised French Lentils with Carrots and Thyme follows this template and finishes with a tablespoon of red wine vinegar once the lentils are tender.

For red lentils: Stir more often. Split lentils sink and stick as they break down, especially in the last 5 minutes.

The salt and acid question. Lentils.org tells you to salt after cooking because salt added early can make lentils tough. Plenty of cooks salt the water from the start and see no difference. Acid is the more reliable problem: tomatoes, wine and vinegar slow softening noticeably. That's why a tomato-based lentil bolognese simmers 35–40 minutes instead of 20. If your lentils are still hard after 40 minutes, acid added too early is the likely cause. Next time, add salt and acid once they're tender.

Method 2: Instant Pot / Pressure Cooker — 8 Minutes to Done

Pressure cooking helps most with whole lentils. It doesn't make them much faster once you count the time to come up to pressure and release it, but it's hands-off and cooks evenly. For red lentils it's mainly a convenience: sauté, add the lentils, seal, and walk away.

• Use 3 cups of liquid per cup of red lentils. The Instant Pot Spiced Indian Lentil Dal blooms mustard seeds and curry leaves in ghee on the sauté setting, then pressure cooks 1 cup of masoor dal in 3 cups of water for 8 minutes.
• Always use a natural release for 10 minutes. A quick release on a starchy lentil dish can spit foam through the valve.
• Deglaze before you seal. Scrape up any browned bits after sautéing. Red lentils are dense and can trigger a burn warning if something is stuck to the bottom.
• Size the pot. A 3-quart Instant Pot Duo Mini handles 1–1½ cups of dry lentils. For a family batch of stew with broth and vegetables, use a 6-quart. Browse the small appliances section for other sizes.

The Instant Pot Vegan Misir Wat Red Lentil Stew is a good first recipe. It toasts 2 tablespoons of berbere with tomato paste, adds 1½ cups of red lentils and 3 cups of broth, and cooks for 12 minutes, which is longer than plain lentils because the stew is thicker.

Slow cooker note: Brown and green lentils do well in a slow cooker. A 7-quart manual model like the Crock-Pot 7-quart slow cooker holds a double batch of the Moroccan stew. Red lentils turn to paste after 6+ hours, so check them at 4.

Method 3: Sheet-Pan & Baked Lentils

The oven gives you two textures the stovetop can't: crisp roasted lentils and a baked one-pan braise.

Crispy roasted lentils: Start with cooked, well-drained brown, green or black lentils. Pat them dry on a towel, toss with 1 tablespoon of oil per 2 cups, add salt, cumin and smoked paprika, and roast in a single layer at 400°F for 20–25 minutes, shaking the pan once. They crisp as they cool. Scatter them over salads and soups the way you'd use croutons. A rimmed GoodCook nonstick baking sheet set keeps them from rolling off.

Sheet-pan supper: The Lentil & Vegetable Sheet Pan Supper soaks green lentils in boiling water for 15 minutes, then roasts them with carrots and zucchini at 400°F for 25–30 minutes. Expect a chewy, nutty bite rather than soft lentils. If you like them softer, simmer them for 10 minutes instead of soaking.

Oven braise: The Maple-Glazed Roasted Root Vegetables and Lentils starts brown lentils, parsnips and sweet potato on the stovetop with 3 cups of broth, then finishes them in the oven for 35–40 minutes. The lentils absorb the broth and the maple glaze. It's the most hands-off way to get a complete dinner from a single oven-safe pot.

5 Red Lentil Recipes: Dals, Soups, and Curries

Red lentils are the weeknight workhorse: 10 minutes of prep, 20–25 minutes of simmering, and a pot that tastes like it took an hour.

1. One-Pot Red Lentil and Coconut Dahl. Everything goes into one pot: red lentils, a can of coconut milk, curry powder, turmeric, diced potato and carrot. Simmer 20 minutes and wilt in a handful of spinach. It's the easiest dal you'll make.

2. Spiced Turkish Lentil Soup with Toasted Paprika and Lemon. At 190 calories a bowl, it's the lightest recipe here. Smoked paprika and cumin bloom in olive oil, and 2 tablespoons of lemon juice go in off the heat.

3. Instant Pot Vegan Misir Wat Red Lentil Stew. Ethiopian berbere lentils with 18 g of protein per serving. Serve with injera or rice, and see our Ethiopian recipes guide for the rest of the spread.

4. Roasted Carrot and Red Lentil Soup with Cumin and Coriander. A pound of carrots roasts at 400°F while the lentils simmer, then everything is blended smooth. Roasting adds a sweetness you can't get from boiling.

5. Spicy Indian-Inspired Red Lentil Soup with Coconut Milk. Garam masala, chili and lime, only partly blended so some lentils keep their texture. For a full stick-blender comparison, see our immersion blender guide. The Turelar 1100W immersion blender is a budget option.

5 French & Green Lentil Recipes: Salads and Braises

These are the recipes where texture matters. Use French or green lentils here. Red lentils would turn every one of them to mush.

1. Braised French Lentils with Carrots and Thyme. Shallots, garlic, carrots, thyme and a bay leaf, finished with red wine vinegar. It's a side dish for roast chicken or salmon, or a main with a fried egg on top. 220 calories, 16 g protein.

2. Chilled French Lentil Salad with Dill and Cucumber. Toss 1½ cups of cooked French lentils with cucumber, red onion and a Dijon-lemon vinaigrette, then chill for 30 minutes. This is the best use for a batch of lentils cooked on Sunday.

3. French Lentil and Mushroom Cassoulet. Twelve ounces of cremini mushrooms, tomato paste and white wine replace the duck and sausage of a classic cassoulet. At 22 g of protein per serving, it's the most filling vegetarian main in this guide.

4. Creamy French Lentil Soup with Carrots and Thyme. Blend half the pot, keep the other half whole, and stir in ½ cup of cream. That gives you body without losing texture.

5. Ethiopian Azifa Lentil Salad with Mustard Dressing. Green lentils cooked for 20–25 minutes "until tender but not mushy," then dressed with lemon, Dijon, tomato, cilantro and a little green chili. Serve it chilled.

Tip for any lentil salad: Dress the lentils while they're still warm. Their skins absorb vinaigrette as they cool, so you get seasoned lentils instead of lentils sitting in a pool of oil.

5 Brown Lentil Recipes: Stews, Sloppy Joes, and Bolognese

Brown lentils are cheap, meaty and forgiving, which makes them the best choice for replacing some or all of the ground meat in a recipe.

1. Hidden Mushroom and Lentil Bolognese with Spaghetti. Finely chopped cremini mushrooms and ¾ cup of brown lentils simmer in a 28-ounce can of crushed tomatoes for 35–40 minutes. 420 calories and 20 g protein per plate.

2. Lentil sloppy joes (make them from the bolognese). We don't have a separate sloppy joe recipe. Instead, make half a batch of the bolognese above without the oregano. Stir in 2 tablespoons of ketchup, 1 tablespoon of brown sugar, 1 tablespoon of Worcestershire (use a vegan version if needed) and 1 teaspoon of yellow mustard. Simmer uncovered for 10 more minutes until it's thick enough to pile on a bun.

3. Authentic Tuscan Lentil and Sausage Soup. Browned Italian sausage, red wine, passata and rosemary. The brown lentils simmer for 40 minutes, long enough to soften fully in the tomato.

4. Vegetable Lentil Shepherd's Pie. A brown-lentil, carrot and pea filling under butter-mashed potatoes, baked 25 minutes at 375°F. It uses 1 cup of already-cooked lentils, which is a good use for leftovers.

5. Slow Cooker Moroccan-Spiced Lentil and Carrot Stew. Cinnamon, cumin, coriander and smoked paprika with 1½ cups of brown lentils, finished with lemon and cilantro. Six servings at 18 g of protein each.

Bonus: The Herbed Lentil Loaf with Tomato Glaze binds cooked brown lentils with oats and breadcrumbs for a meatless-Monday meatloaf that slices cleanly after a 10-minute rest.

5 Lentil Sides, Bowls, and Meal Preps

These recipes turn one batch of cooked lentils into several lunches.

1. Mujadara with Slow-Caramelized Onions and Brown Lentils. Mujaddara is the Levantine lentil-and-rice dish. Deeply browned onions do most of the work, with cumin, cinnamon and lemon. It reheats better than almost any other grain dish.

2. Greek-Style Lentil Salad with Feta and Fresh Herbs. One cup of dry brown lentils, cooked until just tender and cooled, then tossed with 4 ounces of feta, parsley, red onion and a lemon-garlic dressing.

3. One-Pot Lentil and Rice Bowl. Brown lentils and white rice cook together in 1½ cups of broth for 25–30 minutes. The recipe serves two, so double it for four lunches.

4. Harvested Lentil & Sweet Potato Power Bowl. Roasted sweet potato, green lentils, spinach, chickpeas and avocado. At 520 calories and 22 g of protein, it's a real meal, not a side.

5. Baked Spiced Lentil Patties with Tahini Yogurt Sauce. Mashed red lentils seasoned with cumin, coriander and turmeric, baked instead of fried. They freeze well between sheets of parchment.

Pack portions in glass containers like the Pyrex Simply Store 12-piece set, which can go from the fridge to the microwave. For the full weekly routine, see vegetarian meal prep: 10 plant-based bowls. You can also drop any of these recipes into your meal plan to build the shopping list automatically.

What You'll Need: Pantry Staples for Great Lentils

Lentils (buy at least two types). Keep a bag of red for dal and soups and a bag of French or brown for salads and stews. Harvard's Nutrition Source says dried lentils keep for about a year in a sealed container somewhere cool, dark and dry. Old lentils take longer to soften, so if a two-year-old bag won't get tender, age is the likely reason.

Aromatics. Onion, garlic, carrot and celery for European-style pots. Ginger, cumin seeds, mustard seeds and turmeric for dal. Berbere for Ethiopian stews. Smoked paprika for anything that should taste smoky without meat.

Fat for blooming spices. Olive oil, ghee or coconut oil. Toasting spices in fat for 30–60 seconds before the lentils go in is the difference between flat dal and good dal.

Acid to finish. Lemons, red wine vinegar and canned tomatoes, added once the lentils are tender (see Method 1).

Broth. Vegetable or chicken broth instead of water adds noticeable savory depth to brown and green lentils. Red lentils in a heavily spiced dal need it less.

Gear. A fine-mesh strainer, a heavy pot or Dutch oven, and optionally a pressure cooker and immersion blender. Every tool linked in this guide costs less than $110 as of September 2026.

Nutrition in one line: According to the USDA figures in Wikipedia's lentil entry, 100 g of boiled lentils has 114 calories, about 9 g of protein and 7.9 g of fiber. A cooked cup (about 198 g) comes to roughly 226 calories, 18 g of protein and 15 g of fiber. Harvard's guide adds that lentils are high in folate, potassium and polyphenols and low in sodium and saturated fat.

Common pitfalls

• Mushy salad lentils: You used brown or red lentils, or boiled instead of simmering. Switch to French or green lentils and taste from minute 18.
• Lentils that never soften: Tomatoes or vinegar went in too early, or the lentils are old. Add acid at the end and buy from a store that sells a lot of them.
• Scorched dal: Red lentils settle as they break down. Stir every few minutes near the end and add a splash of water if the spoon leaves a trail.
• Bland pot: You skipped blooming the spices. Toast them in fat first, then season again with salt and lemon at the end.
• Burn warning on the Instant Pot: After toasting spices or tomato paste, pour in some of the broth and scrape the bottom completely clean before you add the lentils and seal.

When not to use lentils

If a recipe needs a legume that stays intact through hours of braising, like cassoulet with duck confit or a long-simmered chili, dried beans or chickpeas hold up better than brown lentils. Split red lentils also won't work anywhere you need visible, separate legumes.

FAQ

Do I need to soak lentils before cooking? No. Harvard's Nutrition Source and Lentils.org both say soaking isn't necessary for everyday lentils. Rinse and sort them, then cook. The exception is whole black urad dal for dal makhani, which the Slow-Cooked Dal Makhani with Black Lentils and Cream soaks overnight before a 1½–2-hour simmer.

How do I keep lentils from turning mushy? Choose French, green or black lentils for dishes that need shape. Keep the pot at a gentle simmer, and start tasting at 18 minutes. Red lentils are meant to collapse, so use them only where you want a purée.

Can I substitute one type of lentil for another? Brown and green lentils swap one for one. French lentils can stand in for either and hold their shape better. Red lentils don't substitute for whole lentils, because they cook in about half the time and break down completely.

How long do cooked lentils last? Harvard's guide says up to a week in the fridge and three months in the freezer. For best texture, eat refrigerated lentils within 4–5 days, and freeze portions flat in zip-top bags.

Are lentils a good protein source? Yes. A cooked cup has about 18 g of protein and 15 g of fiber for roughly 226 calories. Eating them with rice or another grain over the course of the day covers the amino acids lentils are low in.
