What You’ll Need
Here’s everything you’ll need to make this creamy slow cooker soup. Keep the ingredients simple and fresh.
- 4 cups fresh broccoli florets, chopped small
- 2 carrots, diced
- 1 small onion, diced
- 2 cloves garlic, minced
- 4 cups chicken or vegetable broth
- 4 tbsp butter
- ¼ cup flour (or cornstarch for gluten-free)
- 1 cup heavy cream
- 1 ½ cups sharp cheddar cheese, shredded
- 1 cup parmesan cheese, freshly grated
- Salt and black pepper, to taste
How to Make This Soup
Step 1: Load up the slow cooker
Add broccoli, carrots, onion, garlic, butter, broth, salt, and pepper. Stir well.
Step 2: Cook until tender
Cover and cook on low for 4–5 hours or high for 2–3 hours, until the broccoli is soft.
Step 3: Thicken the base
In a small bowl, whisk the flour with a few spoonfuls of warm broth from the slow cooker. Stir that slurry back in and cook for another 15 minutes to thicken.
Step 4: Blend until smooth
Once the vegetables are tender and the soup has thickened, blend the entire mixture using an immersion blender (or transfer carefully to a regular blender). Blend until the texture is smooth and creamy.
Step 5: Make it cheesy and rich
Return the blended soup to the slow cooker if needed. Stir in the heavy cream, cheddar, and parmesan. Mix until melted and smooth. Taste and adjust seasoning.
Storage
- Keeps in the fridge for up to 4 days in an airtight container.
- Reheat gently on the stove (low heat only, don’t boil).
- To freeze: do it before adding cream and cheese for best texture..
Top tip
For the creamiest texture, blend before adding the cheese and cream. This keeps the soup silky instead of grainy. And always shred your own cheese because pre-shredded cheese won’t melt as smoothly.

Notes
Semi-sweet chips work best, but you can swap in milk chocolate, dark chocolate, or chopped chocolate chunks for bigger melty pools. Butter:
Unsalted butter is ideal. If using salted butter, reduce the added salt to ¼ teaspoon. Flour:
All-purpose flour only — no cake flour or bread flour for this recipe, as it changes the texture.
