Ingredients

Instructions

  1. Step 1: Preheat oven to 400°F. Place 2 lbs peeled and quartered russet potatoes in a large pot of salted water (1 tsp salt) and bring to a boil. Cook for 15-20 minutes until tender.
  2. Step 2: While potatoes cook, heat 1 tbsp olive oil in a large skillet over medium heat. Add 1 diced medium onion and 2 diced medium carrots, sauté for 5 minutes until softened.
  3. Step 3: Add 1 lb ground beef and 4 minced garlic cloves to the skillet. Cook for 7-8 minutes, breaking up meat, until browned and fragrant.
  4. Step 4: Stir in 2 tbsp tomato paste, 1 tbsp Worcestershire sauce, 1 cup beef broth, 1 cup frozen peas, 1 tbsp all-purpose flour, 1/2 tsp salt, and 1/2 tsp black pepper. Simmer over medium-low heat for 10 minutes until sauce thickens.
  5. Step 5: Drain the potatoes and return to pot. Add 4 tbsp butter, 1/2 cup milk, 1/2 tsp salt, and 1/2 tsp black pepper. Mash until smooth and creamy.
  6. Step 6: Transfer beef mixture to a 9x9-inch baking dish. Evenly spread garlic mashed potatoes over the top. Bake in preheated oven for 20 minutes until edges are golden and bubbling.
  7. Step 7: Remove from oven and let rest for 5 minutes before serving.

How do I store leftover Shepherd's Pie with Garlic-Mashed Potatoes?

Cool fully before storing. Most baked desserts keep at room temperature in an airtight container for 2–3 days, or in the fridge for up to 5 days. Cream- or custard-based desserts must go in the fridge within 2 hours; reheat gently or serve cold per the recipe.

Can I substitute ingredients in Shepherd's Pie with Garlic-Mashed Potatoes?

Yes — most ingredients in this recipe have flexible swaps. For oil, use any neutral high-smoke-point oil (avocado, grapeseed, refined coconut). For aromatics, dried herbs at ⅓ the volume of fresh work in a pinch. The full ingredient list is shoppable on Instacart so you can see substitutes in real time.

How do I scale Shepherd's Pie with Garlic-Mashed Potatoes for a different number of people?

The recipe is written for 4 servings. Multiply each ingredient by (your serving target / 4). Cook time stays roughly the same up to 2x; for 3-4x batches, switch from a skillet to a sheet pan or stockpot so the food isn't crowded — overcrowding steams instead of browns.
