Ingredients

Directions

Make the base

  1. Pour olive oil into a large soup pot and sauté onions and garlic over low heat for 3–5 minutes.

  2. Turn off the heat, cover the pot and let the onion‑garlic mixture steam for 15 minutes.

  3. Add the squash, potato, and carrot and stir the mixture well.

  4. Pour in the stock and bring the soup to a boil.

Simmer and blend

  1. Reduce the heat, cover the pot, and let it simmer for 45 minutes.

  2. Add the seasoning and parsley, stir well, cover the pot, and continue simmering for another 15 minutes.

  3. Blend one third of the soup at a time in a blender or food processor and return it to the original, but clean, pot.

  4. Reheat the soup over low heat, but do not let it come to a boil.

Serve

  1. Serve hot and sprinkle fresh thyme leaves on top of each serving as garnish.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs

What each ingredient does

Onions
Soften and build a sweet, savory flavor base for the soup.
Butternut squash
Provides the main body, sweetness, and smooth texture once blended.
Potato
Adds starch that thickens the soup and gives it a creamier body.
Chicken stock
Supplies the liquid that cooks the vegetables and forms the soup's base.
Olive oil
Carries the aromatics' flavor and helps soften the onions and garlic.

The step that matters

Blend in batches and reheat gently. Blending hot soup in a full blender can build pressure and spray it out, so work in small batches with the lid vented. Keeping the soup below a boil after blending helps prevent scorching and keeps the texture smooth.
