Ingredients for Your Slow Cooker Broccoli Cheddar Soup
Gathering your ingredients is the only real “work” in this recipe. Here’s everything you’ll need to create this hearty and satisfying soup.
Main Ingredients:
- 4 cups fresh broccoli florets, chopped into bite-sized pieces (about 1 large head)
- 1 medium yellow onion, finely diced
- 2 medium carrots, peeled and grated or finely diced
- 3 cloves garlic, minced
- 3 cups low-sodium chicken broth (or vegetable broth for a vegetarian version)
- 1 teaspoon dried mustard powder
- ½ teaspoon smoked paprika
- ¼ teaspoon ground nutmeg (optional but highly recommended)
- Salt and freshly ground black pepper to taste
For the Creamy Base & Cheese:
- ⅓ cup all-purpose flour
- ¼ cup unsalted butter, melted
- 2 cups whole milk or half-and-half
- 2 ½ cups shredded sharp cheddar cheese, plus more for garnish (pre-shredded bags contain anti-caking agents; for the smoothest melt, shred a block yourself!)
- 1 cup shredded Gruyère cheese (or more sharp cheddar for a stronger cheddar flavor)
- ½ cup heavy cream or additional whole milk (for added richness at the end)
Step-by-Step Instructions for Perfect Broccoli Cheddar Soup
Follow these simple, numbered steps for a flawless soup every single time.
Step 1: Prepare the Slow Cooker Base
In your 4-6 quart slow cooker, combine the chopped broccoli, diced onion, grated carrots, and minced garlic. Pour in the chicken broth. Add the dried mustard, smoked paprika, nutmeg, and a pinch of salt and pepper. Gently stir to combine.
Step 2: Create the Roux (The Secret to Creaminess!)
In a separate medium bowl, whisk the melted butter and flour together until it forms a smooth, thick paste. This is called a roux. While whisking constantly, slowly pour in the milk. Whisk vigorously until the mixture is completely smooth and no lumps of flour remain.
Step 3: Combine and Cook
Pour the milk-and-roux mixture into the slow cooker with the vegetables and broth. Stir everything together until well incorporated.
Step 4: Set It and (Almost) Forget It
Cover the slow cooker and cook on HIGH for 3-4 hours or on LOW for 5-6 hours. The soup is ready when the broccoli and carrots are very tender.
Step 5: Thicken and Cheese It!
About 30 minutes before serving, use a potato masher or immersion blender to lightly puree some of the soup right in the pot. This helps thicken the base while leaving plenty of broccoli chunks for texture. If you prefer a completely smooth soup, you can blend it all.
Step 6: The Grand Finale: Adding the Cheese
Turn the slow cooker to the WARM setting. Stir in the heavy cream. Gradually add the shredded cheddar and Gruyère cheese, one handful at a time, stirring until fully melted before adding the next handful. This slow incorporation prevents the cheese from seizing or becoming greasy. Taste and adjust seasoning with more salt or pepper if needed.
Step 7: Serve and Enjoy!
Ladle the hot, creamy soup into bowls. Garnish with extra shredded cheddar, fresh cracked black pepper, or a few small broccoli florets. Serve immediately with crusty bread, bread bowls, or oyster crackers for dipping.
Pro Tips for the Best Broccoli Cheddar Soup
- Cheese Matters: For the creamiest, smoothest melt, always shred your own cheese from a block. Pre-shredded cheese is coated to prevent clumping, which can make your soup slightly grainy.
- Avoid Curdling: Adding the cheese while the soup is too hot or all at once can cause it to break. Using the WARM setting and adding it gradually is key.
- Veggie Prep: Cut the broccoli florets into uniform, bite-sized pieces so they cook evenly. Don’t discard the stalks! You can peel and finely chop them to add more texture and reduce waste.
- Customize It:
- Vegetarian: Use vegetable broth.
- Gluten-Free: Substitute the all-purpose flour with a 1:1 gluten-free flour blend or cornstarch (use 2 tablespoons cornstarch mixed with ¼ cup cold water, added in Step 6).
- Add Protein: Stir in 1-2 cups of diced cooked ham or shredded rotisserie chicken at the same time as the cheese.
- Add Heat: A pinch of cayenne pepper or a dash of hot sauce adds a wonderful kick.
- Storage & Reheating: Store cooled soup in an airtight container in the refrigerator for up to 4 days. Reheat gently on the stove over low heat, stirring frequently. The soup may thicken when chilled; thin it with a splash of milk or broth while reheating. For best texture, it does not freeze well due to the dairy content.
