Crockpot Broccoli Cheese Soup Ingredients
- Broccoli (fresh florets)
- Carrots, celery, and onions (mirepoix mix works well)
- Garlic
- Cheese: sharp cheddar is recommended. Buy a block and grate it yourself for best melting and texture; pre-shredded cheese contains anti-caking agents that affect meltability.
- Broth (chicken or vegetable)
- Half and half (or substitute with heavy cream or milk)
- Salt and pepper
- Flour (optional, for thickening)

How to Make Crockpot Slow Cooker Broccoli Cheese Soup
Detailed measurements and full instructions are included in the recipe section below. The basic steps are:
- Prep the vegetables. Chop the broccoli into florets if needed. Dice carrots, celery, and onion, and mince the garlic.
- Load the slow cooker. Add the broccoli, carrots, celery, onion, and garlic to the slow cooker. Pour broth in until the vegetables are just covered.
- Season. Add salt and pepper to taste and stir.
- Cook low and slow. Cover and cook until the vegetables are tender—usually 4–6 hours on low or 2–3 hours on high.
- Add the cream and cheese. Stir in the half and half, then add grated cheddar in small handfuls, stirring until melted and smooth. Replace the lid and cook until fully combined and heated through.
- Thicken if desired. For a thicker soup, whisk a flour slurry (equal parts flour and water) and stir it in. Let the soup sit to thicken.
- Adjust and serve. Taste and adjust seasoning. Serve in bowls with extra shredded cheese and bread or cornbread for dipping.

Crockpot Slow Cooker Broccoli Cheese Soup
This simple slow cooker recipe produces a creamy, cheesy soup that’s easy to customize. Prep time is short and most of the cooking happens unattended.
Equipment
- Slow cooker
Ingredients (Serves about 8 cups)
- 5 cups fresh broccoli florets
- 1/3 cup chopped onion (white recommended)
- 1/3 cup chopped celery
- 1/3 cup chopped carrots
- 2–3 garlic cloves, minced
- 4 cups broth (chicken or vegetable)
- 1 cup half and half
- 2–3 cups grated cheddar cheese (sharp recommended)
- Salt and pepper to taste
- 2–3 tablespoons all-purpose flour (optional, for thickening)
Instructions
- Add broccoli, onion, celery, carrots, broth, and garlic to the slow cooker. (Sautéing the vegetables first is optional.)
- Cook on High for 2–3 hours or Low for 4–6 hours, until the broccoli and vegetables are tender.
- Stir in cheddar cheese, half and half, and season with salt and pepper.
- Cover and cook on High for 30 minutes, or until the cheese has fully melted into the soup.
- To thicken, whisk 2–3 tablespoons of flour with an equal amount of water to form a slurry, then stir it into the soup. Allow the soup to sit and thicken; use 3 tablespoons if you prefer a thicker texture.
- Taste and adjust seasonings. Ladle into bowls and top with extra cheese if you like. Serve with bread or cornbread for dipping.
Notes
- Always grate cheese from a block for the best melting texture—pre-shredded cheese contains anti-caking agents that change the final result.
- Frozen broccoli can be used but may require extra cook time and can release additional moisture that slightly thins the soup.
- If the soup ends up too thin, add more broth and simmer, or use a slurry as noted above to thicken. If too thick, thin with additional broth.
- For a smooth soup, blend with an immersion blender or countertop blender. Even blended broccoli can retain some texture.
- Half and half can be replaced with heavy cream for a richer soup or with milk for a lighter version. Plant-based milks will yield a thinner texture.
- Store leftovers tightly covered in the refrigerator for 3–4 days. Freeze in portions for longer storage.

Frequently Asked Questions and Pro Tips
Cheddar is ideal. The longer it’s aged, the more pronounced the flavor: mild is creamy, medium is slightly bolder, sharp has a clear bite, and extra-sharp is very pronounced. Use what you like, but grate from a block for best melting.
Can I use frozen broccoli?
Yes. Expect to add a bit more cook time and note that frozen broccoli releases moisture, which can thin the soup slightly.
Can I blend or puree the soup?
Yes. For a smooth soup use an immersion or countertop blender. Even blended broccoli may leave some texture.
How do I thicken watery soup?
Use a flour slurry: combine equal parts flour and water and stir into the cooked soup. Start with 1 tablespoon of each and increase as needed. Many cooks use about 3 tablespoons total for noticeable thickening.
How long will leftovers last?
Stored tightly covered in the refrigerator, the soup keeps 3–4 days. You can also freeze portions for several months.

Variations and Topping Ideas
