Ingredients Needed

• 5 tablespoons unsalted butter (divided)
• 1 tablespoon olive oil
• 3 cups mirepoix (or use 1 cup diced carrots, 1 cup diced celery, and 1 cup diced yellow onion)
• 2 teaspoons minced garlic
• 1-1/2 pounds baby potatoes (gold or red, diced (4 cups))
• 1-1/2 teaspoons Italian seasoning
• 3/4 teaspoon salt
• 3/4 teaspoon pepper
• 3 cups chicken stock (or broth, see note 1)
• 2 cups frozen broccoli florets (thawed and finely chopped)
• 1 cup frozen corn
• 6 tablespoons flour
• 3 cups whole milk
• 1/2 cup heavy cream
• 2 cups shredded sharp Cheddar cheese
• Hearty buttered bread (optional, for serving)
• Fresh herbs (optional, for serving (parsley or thyme))

Ingredient Notes & Substitutions:

Dairy-Free: Use plant-based milk (almond, soy, or oat milk) and dairy-free cheese alternatives to make this recipe dairy-free. Nutritional yeast can also add a cheesy flavor.

Gluten-Free: Ensure your chicken stock is gluten-free. Use a gluten-free flour blend or cornstarch to thicken the soup.

Cheese: Sharp Cheddar cheese provides the best flavor, but mild or medium Cheddar can also be used. Freshly grated cheese melts more smoothly. For alternatives, consider Gruyere or Monterey Jack.

Mirepoix: Use pre-chopped or frozen mirepoix for convenience. If dicing your own vegetables, aim for uniform sizes for even cooking. You can learn more about the classic French technique of mirepoix from Allrecipes.

Broth: Vegetable broth can be used for a vegetarian option.

How to Make Creamy Vegetable Soup

Step 1: Sauté Aromatics

In a large pot, melt 1 tablespoon of butter with olive oil over medium heat. Add the diced carrots, celery, and onion (mirepoix). Sauté for 5–7 minutes until softened and fragrant. You’ll know it’s ready when the onions are translucent and the aroma is savory and sweet. This step is crucial for building a flavorful base for your creamy vegetable soup. Add the minced garlic and cook for another 30 seconds.

Step 2: Simmer Vegetables

Stir in the chopped potatoes, Italian seasoning, salt, pepper, and chicken stock. Bring the mixture to a boil over medium-high heat, then reduce the heat to medium. Cover the pot and cook for 10–15 minutes, or until the vegetables are crisp-tender. The gentle simmer will fill your kitchen with a comforting aroma. Stir in the thawed broccoli and frozen corn. Cook for an additional 2–3 minutes, until the vegetables are tender and heated through, retaining their vibrant color and texture. Speaking of broccoli, you might also enjoy this cream of broccoli soup recipe.

Step 3: Make the Cream Sauce

Meanwhile, in a medium saucepan, melt the remaining 4 tablespoons of butter over medium heat. Stir in the flour and whisk constantly for 1 minute. This creates a roux, which will thicken the soup. Slowly pour in the milk, whisking continuously until smooth, ensuring there are no lumps. Cook, stirring constantly, until the sauce thickens and gently boils – it should be thick enough to coat the back of a spoon. Finally, stir in the heavy cream and remove the saucepan from the heat. You can read more about the role of a roux in thickening sauces from Escoffier.

Step 4: Combine and Melt Cheese

Pour the milk mixture into the large pot with the vegetables and stir well to combine. Lower the heat to low. Add the shredded Cheddar cheese a handful at a time, stirring until each addition is completely melted and smooth before adding the next. This prevents the cheese from clumping. Taste the soup and adjust the seasonings as needed to your preference.

Step 5: Serve with Pesto Swirl

Serve the creamy vegetable soup warm, garnished with fresh parsley or thyme, alongside toasted and buttered pieces of bread, if desired. For that extra touch of flavor and visual appeal, add a swirl of your favorite basil pesto just before serving. Enjoy!

Freezing and Reheating Instructions

Freezing: Allow the soup to cool completely before transferring it to airtight containers or freezer bags. Portion the soup into individual servings for easy thawing and reheating.

Thawing: Thaw the frozen soup overnight in the refrigerator. For faster thawing, place the freezer bag in a cold water bath.

Reheating: Reheat the soup gently on the stovetop over medium-low heat, stirring frequently to prevent scorching. Adding a splash of milk or cream during reheating can help restore the creamy texture.

Texture: The texture of the soup may change slightly after freezing and thawing. Using an immersion blender after reheating can help restore a smoother consistency if needed.

Pro Tips & Troubleshooting

Here are some of my top tips for making the best creamy vegetable soup, plus some common mistakes to avoid:

Pro Tips:
