Ingredients Needed for this Recipe
- Fresh Broccoli – Cut into small florets so it cooks evenly.
- Onion – I like to add half of a large onion. Dice it into small pieces so that they cook in the broth.
- Garlic – it doesn’t matter whether you mince it yourself or buy it minced in the produce section of the grocery store.
- Cheddar Cheese Soup – this is the star ingredient in this soup {besides the fresh broccoli}. Adding this cheddar cheese soup adds so much wonderful flavor.
- Evaporated Milk -a couple of cans of evaporated milk make this recipe come together quickly.
- Chicken {or vegetable} Stock – to thin the soup but also add flavor.
- Cornstarch – used in the last 30 minutes as a thickener.
- Cheddar Cheese – Added as a topping, freshly grated cheese always melts best.

How to Make Crock Pot Broccoli Cheese Soup
- Gather together the fresh broccoli florets, diced onion and minced garlic.
- In a large bowl combine the cheddar cheese soup, evaporated milk and chicken {or vegetable} stock. Whisk so that all of the ingredients are nicely combined.


- Add the fresh broccoli, diced onion, minced garlic and cheddar soup mixture into your crock pot. Then add the salt and pepper. Stir to combine all of the ingredients. Cover with the lid and set the crock pot on low for 4 hours.
- In the last 30 minutes of cooking stir to see if your soup has thickened at all. If it hasn’t, combine the cornstarch and milk {or water} in a small bowl. Whisk to be sure that the cornstarch is dissolved in the water. Add the mixture to the soup and stir to incorporate it. Allow the soup to cook for an additional 30 minutes.


- After 30 minutes, serve Crock Pot Broccoli Cheese Soup with freshly grated cheddar cheese.
Expert Tips
- Cut the broccoli into small florets. This keeps every piece bite-sized and helps it cook evenly.
- Mince the onion well. If the pieces are too large, they won’t cook down as nicely during the 4-hour cook time.
- Use a crock pot liner. It makes cleanup so much easier.
- Grate your own cheddar cheese for the topping. Pre-shredded cheese is coated in a substance that keeps it from melting as smoothly as freshly grated.
Storage Instructions
Store leftover Crock Pot broccoli cheese soup in an airtight container in the refrigerator for up to 3 days. This slow cooker cheesy broccoli soup makes great leftovers for busy weeks!
Recipe FAQs
If the soup isn’t thick enough for you with the first addition of cornstarch, use the same amount again. This should be enough. Just be sure to give it enough time to warm up so the soup will thicken.
Yes, you can use frozen broccoli in this soup. Just know that the texture of the broccoli will be a bit softer than if you use fresh broccoli.
I love to serve this slow cooked Broccoli Soup with some kind of bread. This One Rise French Bread is always a good option but if you don’t have time try these Easy Cheesy Breadsticks.
