The Ingredients You’ll Need

Crockpot broccoli cheese soup is made with just a few simple ingredients – nearly half of them are just seasonings! For full ingredient amounts and directions, scroll to the printable recipe card at the bottom of this post.

  • Broccoli: Fresh broccoli florets, you can also use frozen if you prefer!
  • Chicken Broth: Or vegetable broth.
  • Onion: Any color, diced. We often use sweet onions or yellow onions here.
  • Garlic: Fresh, minced garlic. (Hate mincing garlic? A garlic press makes it much easier!)
  • Seasonings: Celery salt, onion powder, salt, and black pepper.
  • Evaporated Milk: Evaporated milk is less likely to separate during slow cooking than other dairy products.
  • Cheese: Sharp cheddar cheese, shredded.
  • Cornstarch (Optional): If you want to thicken up the soup, you’ll want a little bit of cornstarch.

What Is the Best Melting Cheese for Soup?

The best cheese for melting is freshly shredded off the block, but we know you don’t always want to shred our own. If you buy pre-shredded cheese, look for the “easy melt” kind. Other good melting cheeses include Colby, Colby-jack, fontina, and gruyere. However, we encourage you to at least use half cheddar (or Colby – the flavor is similar) in this soup so that it keeps its classic cheddar taste.

How to Make Broccoli Cheddar Soup In Crock Pot

With this easy slow cooker recipe, you hardly have to lift a finger. We love just throwing everything in the crockpot and walking away for a bit.

  • Cook the Veggies and Seasonings. Add your broccoli, broth, onion, garlic, celery salt, onion powder, salt, and pepper to the crockpot. Stir everything together, and cover the slow cooker with the lid. Cook on LOW for 4 to 6 hours, or on HIGH for 2 to 3 hours.
  • Make it Creamy: When you are ready to serve, add the evaporated milk and cheese to the pot. Stir well until the cheese has melted.
  • Thicken If Needed: If you like a thicker soup, whisk a couple of tablespoons of cornstarch with the same amount of water. Pour this slurry into the soup, stir it in well, and cover the crockpot with the lid. Let the soup simmer for about 10 minutes, till thickened. 
  • Enjoy! Taste the soup, and season it with additional salt and pepper, as needed. Serve warm topped with additional shredded cheese, and crispy bacon, if desired.

Helpful Tips

A few helpful tips are always, well, helpful! These are a few special tricks of the cooking trade that we learned while developing this creamy, cheesy soup recipe:

  • Prepping Broccoli: You’ll want to chop the broccoli into small, bite-sized pieces, and make sure to scoop all of the little bits that fall off into the crockpot as well, for lots of broccoli flavor! You can also use the broccoli stalk – just peel off the tough outer layer with a potato peeler, and then chop the tender inside into small pieces.
  • Frozen Broccoli: You can use frozen broccoli in this recipe if you prefer. You do not need to thaw it, just add it straight from the freezer to the crockpot.
  • Evaporated Milk: You can substitute the evaporated milk for half & half or whole milk, but evaporated milk has less chance of curdling in the crockpot. It is also as creamy as half and half, but with fewer calories.
  • Pureed Soup: If you’d like a smooth soup, just blend it with your immersion blender. Alternatively, you can finely chop the broccoli, let it cook until tender, and then mash with a potato masher.
  • Add Heat: If you like spice, a little bit of cayenne pepper or crushed red pepper flakes add a nice kick.

Storing and Reheating Slow Cooker Broccoli Cheese Soup

You can store this soup for up to five days in an airtight container in the refrigerator. When you’re ready to serve, just reheat the desired amount in a saucepan on the stove, or in a microwave-safe bowl in the microwave. Heat this soup gently (on low heat on your stove, or in short microwave bursts). Overheating it can cause scorching and texture changes.

Can I Freeze This?

Unfortunately, we can’t recommend freezing this soup. Creamy soups like crockpot broccoli cheese soup don’t freeze well, and turn watery and grainy once they’re thawed out again! If this recipe makes too much for you to enjoy at once, we recommend making half a batch.
