Ingredients
A short list of simple ingredients creates this creamy broccoli soup.
- 4 cups broccoli florets
- 1 cup shredded carrots
- 1 small onion, diced
- 3 tbsp butter
- 3 tbsp all-purpose flour
- 4 cups chicken or vegetable broth
- 1 cup heavy cream or half-and-half
- 2 cups shredded sharp cheddar
- Salt and black pepper to taste
Fresh broccoli gives the best texture and color, though frozen florets work in a pinch. Sharp cheddar melts smoothly and adds the classic flavor. Heavy cream creates the richest finish, while half-and-half keeps things a bit lighter. Any good broth works, but chicken broth adds extra depth. Season generously at the end once the cheese is stirred in.

Step-by-step instructions
These easy steps create a creamy Crock-Pot broccoli cheddar soup.
Step 1: Add the vegetables
Place the broccoli florets, shredded carrots, and diced onion into the slow cooker. Spread them evenly so they cook at the same rate.
Step 2: Add butter and flour
Drop the butter pieces on top of the vegetables. Sprinkle the flour evenly over everything to help thicken the finished soup.
Step 3: Pour in the broth
Pour the chicken or vegetable broth over the vegetables and seasonings. Stir gently once to distribute the flour and butter.
Step 4: Season lightly
Add a pinch of salt and black pepper. You can adjust the seasoning later after the cheese is added.
Step 5: Cook on low
Cover the slow cooker and cook on low for four to five hours. The vegetables should be very tender when ready.
Step 6: Stir the soup
Remove the lid and stir the soup well. The flour and melted butter will have begun to thicken the broth slightly.
Step 7: Add cream and cheese
Pour in the heavy cream and add the shredded cheddar. Stir continuously until the cheese melts into a smooth, creamy sauce.
Step 8: Finish and serve
Taste and adjust salt and pepper as needed. Ladle the hot soup into bowls and serve immediately while it is still creamy.
Tips & common mistakes
A few careful details keep the soup silky and full of flavor.
- Cut broccoli into even florets for uniform cooking

Frequently asked questions
Here are answers to the questions people ask most about this soup.
Can I cook this on high instead?
Yes. Cook on high for two to three hours until the vegetables are tender. Stir in the cream and cheese at the end as usual.
Will the cheese get grainy?
Add the cheese only after the soup is fully cooked and off the heat. Stir gently until melted for the smoothest texture.
Can I freeze the leftovers?
The soup freezes reasonably well for up to two months. Thaw overnight in the refrigerator and reheat gently, stirring often.
What if the soup is too thin?
Mix a little extra flour with cold water and stir it in during the last thirty minutes of cooking. It will thicken as it simmers.
