Ingredients Overview

This soup is flexible, but here are the building blocks for a flavorful and creamy result:

Aromatics

• Onion, Celery & Garlic: These form the flavorful base and build aroma right from the start.

• Carrots: Sweet and tender, they add color and body.

Vegetables

Choose a mix of your favorites. Common options:

• Potatoes (Yukon gold, red, or russet)

• Broccoli or cauliflower florets

• Green beans

• Corn

• Peas

• Zucchini or squash

Frozen veggies work well too—just stir them in near the end of cooking.

Broth

Vegetable broth is ideal, keeping the soup vegetarian. Use low-sodium to control salt levels. Chicken broth works too if not vegetarian.

Creaminess

• Heavy cream or half-and-half adds richness and silky texture.

• For a lighter version, use whole milk or unsweetened plant milk.

• Roux (flour + butter) thickens the broth into a smooth, velvety finish.

Herbs & Seasonings

• Dried thyme or Italian seasoning

• Bay leaf (optional)

• Salt & black pepper

• Fresh parsley for garnish

Butter & Olive Oil

Used for sautéing and to add depth. Butter gives a rich flavor, while olive oil keeps it light.

Step-by-Step Instructions

1. Sauté the Aromatics

In a large pot, melt 2 tablespoons butter with 1 tablespoon olive oil over medium heat.

Add:

• 1 diced onion

• 2–3 chopped carrots

• 2 chopped celery stalks

Cook for 5–7 minutes until softened and aromatic. Add 3 minced garlic cloves and cook for 1 more minute.

2. Add Vegetables and Broth

Stir in:

• 2 cups diced potatoes

• 2–3 cups chopped veggies (e.g., green beans, broccoli, peas, corn)

Pour in 4 cups of vegetable broth. Add 1 teaspoon thyme, salt and pepper to taste, and a bay leaf if using. Bring to a gentle boil.

Reduce heat and simmer for 15–20 minutes, or until potatoes are tender.

3. Thicken the Soup

In a small bowl, whisk 2 tablespoons flour with ½ cup water or broth until smooth. Stir into the soup and simmer 5 more minutes to thicken.

Alternatively, make a roux in a separate pan and stir it in.

4. Add Cream

Turn heat to low and stir in:

• 1 cup heavy cream or half-and-half

Warm gently—do not boil after adding cream, or it may curdle. Adjust seasoning as needed.

5. Serve and Garnish

Remove bay leaf. Ladle soup into bowls and top with chopped parsley or shredded cheese if desired.
