Soup Base

  • 3 cups vegetable broth or chicken broth
  • 1 cup heavy cream
  • 1 cup whole milk
  • 2 tablespoons butter
  • 2 tablespoons all-purpose flour

How to Make Broccoli Cheddar Soup Instant Pot

Step 1: Sauté the Aromatics

Turn the Instant Pot to Sauté mode.

Melt the butter before adding:

  • Onion
  • Celery
  • Carrots

Cook for about 4 minutes until softened.

Add garlic and cook for another minute until fragrant.

Step 2: Add Broccoli and Broth

Pour in the broth.

Add broccoli florets along with the seasonings.

Stir everything together.

Step 3: Pressure Cook

Secure the lid.

Set the valve to Sealing.

Cook on High Pressure for 2 minutes.

Allow a 5-minute natural release, then carefully perform a quick release.

Step 4: Blend

Use an immersion blender to blend the soup to your desired consistency.

Some prefer completely smooth while others enjoy chunks of broccoli remaining.

Step 5: Make It Creamy

Turn the Instant Pot back to Sauté (Low).

Whisk together the flour with a small amount of milk until smooth.

Slowly stir into the soup.

Add remaining milk and heavy cream.

Simmer for 3–5 minutes.

Step 6: Add the Cheese

Turn off the heat.

Gradually stir in freshly shredded cheddar cheese.

Allow each handful to melt before adding more.

Never boil after adding cheese, as it may separate.

Tips for Perfect Broccoli Cheddar Soup

Always Use Freshly Shredded Cheese

Pre-shredded cheese contains anti-caking agents that prevent smooth melting.

Freshly grated cheddar creates a silky texture.

Choose Sharp Cheddar

Sharp cheddar provides a deeper, richer flavor than mild cheese.

Extra-sharp cheddar gives the soup even more character.

Don't Overcook the Broccoli

Pressure cooking for only two minutes preserves both color and flavor.

Blend Carefully

For the creamiest soup, blend most of the vegetables while leaving small broccoli pieces for texture.

Best Cheese Choices

Although cheddar is classic, you can experiment with:

  • White cheddar
  • Extra sharp cheddar
  • Gouda
  • Gruyère
  • Monterey Jack
  • Parmesan (small amount)

Mixing cheeses often creates a more complex flavor.

Variations

Low-Carb Version

Skip the flour.

Use:

  • Heavy cream
  • Cream cheese
  • Extra cheddar

This naturally thickens the soup.

Vegetarian Version

Use vegetable broth instead of chicken broth.

Protein-Packed Version

Add:

  • Rotisserie chicken
  • Diced ham
  • Cooked bacon
  • Turkey

Extra Vegetable Version

Include:

  • Cauliflower
  • Spinach
  • Kale
  • Mushrooms

Serving Suggestions

Serve with:

  • Crusty artisan bread
  • Garlic bread
  • Bread bowls

  • Homemade croutons

Storage Instructions

Refrigerator

Store in an airtight container for up to 4 days.

Freezer

Freeze for up to 3 months.

Because dairy soups can separate slightly, stir well while reheating.

Reheating Tips

Reheat slowly over low heat.

If needed, stir in a splash of milk or broth to restore creaminess.

Avoid boiling.

Common Mistakes to Avoid

Adding Cheese Too Quickly

Only use enough to lightly thicken.

Over-Blending

Leaving some broccoli pieces creates a better texture.
