Step-by-Step Instructions for Simple Broccoli Cheese Soup

Saute aromatics: Heat 1 tablespoon olive oil in a large pot over medium heat. Add 1 chopped yellow onion and 2 minced garlic cloves. Cook until softened (about 5 minutes).
Add broccoli and broth: Stir in 4 cups fresh broccoli florets (cut into small, uniform pieces) and 4 cups vegetable broth. Bring to a simmer.
Cook until tender: Cover and simmer for 15-20 minutes, until broccoli is very tender when pierced with a fork.
Blend partially: Use an immersion blender to puree about half the soup directly in the pot. (Alternatively, carefully transfer 2 cups of soup to a regular blender, blend until smooth, then return to pot.)
Add cheese: Reduce heat to low. Stir in 1½ cups shredded sharp cheddar cheese, ½ cup milk, ½ teaspoon mustard powder, salt and pepper to taste. Do not boil after adding cheese.
Adjust consistency: If too thick, add more broth or milk, ¼ cup at a time. If too thin, simmer uncovered for a few more minutes.
Serve immediately: Ladle into bowls and garnish with extra cheese, croutons, or fresh herbs.

Common Mistakes to Avoid

Even simple recipes can go wrong. Here's what to watch for when making your easy broccoli cheese soup:

Adding cheese to boiling soup: High heat causes cheese to become stringy and separate. Always reduce to low heat before adding cheese.
Using pre-shredded cheese: These contain anti-caking agents that prevent smooth melting. Always shred your own cheese from a block.
Overcooking broccoli: This leads to dull color and mushy texture. Cook just until fork-tender.
Skipping the blending step: Blending part of the soup creates creaminess without heavy cream or roux.

Simple Variations for Different Dietary Needs

This basic recipe adapts easily to various preferences:

Gluten-Free Broccoli Cheese Soup

The beauty of this recipe is it's naturally gluten-free since it doesn't use flour or cream of mushroom soup. Just ensure your broth is certified gluten-free.

Dairy-Free Version

For a dairy-free simple broccoli cheese soup:

Substitute vegetable broth for any dairy-based liquids
Use dairy-free cheese alternative (cashew-based works well)
Add ¼ cup raw cashews (soaked) blended with the soup for creaminess

Extra Protein Option

Storage and Reheating Tips

This simple broccoli cheese soup stores well:

Refrigeration: Keep in airtight container for up to 4 days

Note: The texture may change slightly after freezing due to the dairy content, but flavor remains excellent.

Frequently Asked Questions

Can I use frozen broccoli for simple broccoli cheese soup?

Yes, frozen broccoli works well in this recipe. Thaw and thoroughly pat dry before using to prevent excess water in your soup. You may need to cook it 2-3 minutes longer than fresh broccoli to achieve the same tenderness.

Why isn't my broccoli cheese soup creamy?

Creaminess comes from blending part of the soup. If your soup isn't creamy enough, blend an additional cup of the soup mixture. Avoid adding more cheese as this can make the soup grainy. The natural starches from the broccoli create the perfect creamy texture when properly blended.

How can I prevent my cheese from clumping in broccoli soup?

To prevent clumping: 1) Shred your own cheese from a block (pre-shredded contains anti-caking agents), 2) Add cheese off direct heat (soup should be warm but not boiling), 3) Stir constantly as you add cheese in small handfuls, and 4) Use sharp cheddar which melts more smoothly than mild varieties.

Can I make broccoli cheese soup without broth?

While broth provides the best flavor base, you can substitute with water plus 1 tablespoon of nutritional yeast for umami flavor. However, the soup won't be as rich. For best results in this simple broccoli cheese soup recipe, use a good quality vegetable or chicken broth.

How do I fix broccoli cheese soup that's too thin?

If your soup is too thin, simmer uncovered for 5-10 minutes to reduce and thicken. Alternatively, blend an additional cup of the soup mixture to release more starch from the broccoli. Avoid adding flour or cornstarch as this defeats the purpose of a simple, roux-free broccoli cheese soup.
