The Key Ingredients for a Perfect Soup
The beauty of this slow cooker recipe lies in its simplicity. We’re using wholesome, easy-to-find ingredients to build incredible depth of flavor.
For the Soup Base:
- Broccoli: The star of the show! Fresh broccoli florets provide the best texture and flavor.
- Onion & Garlic: These aromatics create the essential flavor foundation for our soup.
- Chicken or Vegetable Broth: Use a quality broth as it makes up a significant portion of the liquid.
- Evaporated Milk & Heavy Cream: The secret duo for an ultra-creamy soup that resists curdling.
For the Cheesy Finish:
- Sharp Cheddar Cheese: For that classic, tangy cheese pull. Always shred your own cheese from a block for the smoothest melt.
- Cornstarch: A simple slurry thickens the soup to the perfect consistency.
- Seasonings: A touch of mustard powder, paprika, salt, and black pepper enhances all the other flavors.
How to Make Slow Cooker Broccoli Cheese Soup
Making this soup is as easy as 1-2-3. Follow these simple steps for a foolproof result every time.
- Combine Ingredients: Add the broccoli florets, diced onion, minced garlic, and chicken broth to the bowl of your slow cooker. Stir to combine.
- Slow Cook: Cover and cook on low for 4-6 hours or on high for 2-3 hours, until the broccoli is very tender.
- Blend for Smoothness: Use an immersion blender to blend about half of the soup directly in the slow cooker. This creates a creamy base while leaving some nice texture. If you don’t have an immersion blender, carefully transfer half the soup to a regular blender and puree until smooth, then return it to the slow cooker.
- Create the Creamy Base: In a separate bowl, whisk together the evaporated milk and cornstarch to create a slurry. Slowly stir this mixture, along with the heavy cream, into the soup.
- Melt the Cheese: Turn the slow cooker to high. Add the shredded cheddar cheese in handfuls, stirring continuously until each addition is fully melted. Stir in the mustard powder, paprika, salt, and pepper. Let the soup heat through for another 15-20 minutes, allowing it to thicken. Do not let it boil.
- Serve and Enjoy: Ladle the hot soup into bowls and serve immediately with your favorite toppings like extra cheese, croutons, or crispy bacon.

Pro Tips for the Creamiest Broccoli Cheese Soup
- Shred Your Own Cheese: Pre-shredded cheese is coated with anti-caking agents that can make your soup grainy. For the smoothest, meltiest result, always buy a block of sharp cheddar and shred it yourself.
- Don’t Boil the Dairy: After adding the milk, cream, and cheese, keep the heat gentle. Boiling can cause the dairy to curdle and separate.
- Taste and Adjust: Always taste your soup before serving. You may need to add a bit more salt or a pinch of pepper to make the flavors pop.
Variations and Fun Add-Ins
While this recipe is fantastic as is, feel free to customize it! Here are a few ideas:
- Add Carrots: For a Panera-inspired version, add one cup of shredded carrots along with the broccoli.
- Make it Spicy: Add a pinch of cayenne pepper or a dash of your favorite hot sauce for a little kick.
- Protein Boost: Stir in some shredded rotisserie chicken or crispy crumbled bacon at the end. For another great slow cooker meal, try this Crockpot BBQ Chicken.
What to Serve With Your Soup
This Slow Cooker Broccoli Cheese Soup is a meal in itself, but it pairs wonderfully with a few classic sides. Nothing beats dipping a crusty piece of bread or a classic grilled cheese sandwich into the creamy broth. A simple side salad, like this Cucumber Caprese Salad, can also lighten up the meal. For a heartier option, serve it alongside fluffy Air Fryer Baked Potatoes.
Frequently Asked Questions
Yes, you can use frozen broccoli florets. There’s no need to thaw them first. Just add them directly to the slow cooker; you may need to add about 30-60 minutes to the initial cooking time.

The key is to avoid high heat after adding dairy. Add the milk, cream, and cheese at the end of the cooking process over low or gentle heat. Stir constantly while the cheese melts and do not let the soup come to a boil.
This soup is wonderful on its own or served in a bread bowl. It also pairs perfectly with crusty bread for dipping, a grilled cheese sandwich, or a fresh green salad.
A good quality sharp or extra-sharp cheddar cheese provides the best flavor. For the smoothest texture, it’s crucial to buy a block of cheese and shred it yourself, as pre-shredded cheeses have additives that can make the soup grainy.
