Creamy Broccoli & Cheese Soup is a rich, velvety comfort food classic that balances tender broccoli florets with sharp cheddar in a smooth, savory base. Proper technique is critical: controlling heat prevents grainy cheese, while correct thickening ensures a luxurious texture without heaviness.
This guide walks through ingredient selection, technique, and professional-level tips so you achieve restaurant-quality results at home.
Why This Recipe Works
- A balanced roux provides stable thickening
- Gradual cheese incorporation prevents separation
- Fresh broccoli delivers texture contrast
- Low, controlled heat maintains smooth emulsion
Ingredient Spotlight
Broccoli contributes fiber, mild bitterness, and color contrast that balances the richness of cheese and cream.
Ingredients (Serves 4–6)
- 4 tablespoons unsalted butter
- 1 small yellow onion, finely diced
- 2 cloves garlic, minced
- ¼ cup all-purpose flour
- 2 cups vegetable or chicken broth
- 2 cups whole milk (or half-and-half)
- 3 cups fresh broccoli florets (finely chopped)
- 1 large carrot, grated (optional for sweetness)
- 2 cups sharp cheddar cheese, freshly grated
- ½ teaspoon salt (adjust to taste)
- ¼ teaspoon black pepper
- Pinch of paprika (optional)
Step-by-Step Instructions
1. Build the Aromatic Base
In a large pot over medium heat, melt butter.
Add onion and sauté 3–4 minutes until translucent.
Add garlic and cook 30 seconds until fragrant.
2. Create the Roux
Sprinkle flour over the mixture and stir continuously for 1–2 minutes.
The flour should cook but not brown.
This forms the thickening structure of the soup.
3. Add Liquid Gradually
Slowly whisk in broth to prevent lumps.
Add milk and whisk until smooth.
Simmer gently for 5–7 minutes until slightly thickened.
4. Cook the Vegetables
Add chopped broccoli and grated carrot.
Simmer 10–15 minutes until broccoli is tender but bright green.
5. Incorporate Cheese (Critical Step)
Reduce heat to low.
Add shredded cheddar gradually, stirring constantly.
Do not boil after cheese is added. High heat causes separation and graininess.
6. Adjust Consistency
For thicker soup:
- Simmer longer before adding cheese
- Blend partially
For thinner soup:
- Add additional warm milk or broth
Texture & Flavor Profile
- Smooth, creamy base
- Tender broccoli pieces
- Sharp, savory cheddar notes
- Slight sweetness from carrot
- Balanced richness
Professional Tips for Perfect Soup
Use Freshly Grated Cheese
Pre-shredded cheese contains anti-caking agents that inhibit smooth melting.
Avoid High Heat
Cheese emulsions break at high temperatures.
Blend Strategically
For a smoother texture, use an immersion blender to partially purée the soup.
Season at the End
Cheddar adds salt; final seasoning should follow cheese incorporation.
Variations
Extra Creamy Version
Replace 1 cup milk with heavy cream.
Lighter Option
Use low-fat milk and reduce butter to 2 tablespoons.
Spicy Kick
Add cayenne pepper or diced jalapeño.

Creamy Broccoli & Cheese Soup
Ingredients
- 2 tbsp butter or olive oil
- 1 small onion, diced
- 2 garlic cloves, minced
- ¼ cup all-purpose flour
- 2 cups chicken or vegetable broth
- 2 cups whole milk or half-and-half
- 1½ lbs (680g) fresh broccoli florets, chopped (stems peeled & diced optional)
- 2 cups shredded sharp cheddar cheese
- ½ tsp Dijon mustard (optional, enhances flavor)
- Salt & black pepper to taste
- Optional: pinch of nutmeg, ½ cup carrots for color
Instructions
- Sauté aromatics: In a large pot, melt butter over medium heat. Add onion; cook 4–5 minutes until soft. Stir in garlic; cook 30 seconds.
- Make roux: Sprinkle flour over onions; stir 1–2 minutes until golden.
- Add liquids: Gradually whisk in broth and milk. Bring to a gentle simmer.
- Cook broccoli: Add broccoli (and carrots if using). Simmer 10–12 minutes, until broccoli is tender.
- Blend (optional): For ultra-smooth texture, blend 2–3 cups of soup, then return to pot. Or leave chunky!
- Add cheese: Reduce heat to low. Stir in cheddar and Dijon until melted and smooth.
- Season with salt, pepper, and optional nutmeg.
💡 Pro Tips:
– For extra creaminess, stir in 2 oz cream cheese with the cheddar.
– Use full-fat dairy for best texture—low-fat may cause separation.
– Make it vegetarian: use veggie broth and check cheese for rennet.
