Instructions

  1. Step 1: Preheat oven to 425°F. Toss diced beets, parsnips, and carrots with 1 tbsp olive oil, salt, and pepper on a baking sheet. Roast for 25-30 minutes until tender and caramelized at edges.
  2. Step 2: Heat a large pot over medium heat. Add diced onion and cook for 5 minutes until softened, stirring occasionally.
  3. Step 3: Add minced garlic and cook for 1 minute until fragrant, stirring constantly to avoid burning.
  4. Step 4: Stir in roasted vegetables, chicken stock, salt, and pepper. Bring to a simmer and cook uncovered for 15 minutes to develop flavors.
  5. Step 5: Remove pot from heat. Stir in fresh dill and let sit for 5 minutes to infuse. Adjust salt and pepper to taste before serving.

Frequently asked questions

How long does Slow-Simmered Root Vegetable Soup take to make?

Total time is about 65 minutes (20 min prep + 45 min cook). Most home cooks find this fits comfortably into a weeknight; double the batch on Sunday for two dinners.

How do I store leftover Slow-Simmered Root Vegetable Soup?

Cool to room temperature within 2 hours, then store in an airtight container in the fridge for up to 4 days. Reheat covered in a 350°F oven for 10-12 minutes, or microwave at 70% power in 60-second bursts to keep beets from drying out.

Can I substitute ingredients in Slow-Simmered Root Vegetable Soup?

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 Slow-Simmered Root Vegetable Soup 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.

What goes well with Slow-Simmered Root Vegetable Soup?

American whole30 like this pair well with a compliant starch (roasted sweet potato, cauliflower rice, or plantains), a crisp salad dressed with olive oil and lemon, and sliced fruit. Skip grains, legumes, dairy and added sugar — none of them are Whole30-compliant. Tap "Plan a meal with the AI" to get specific side suggestions.
