Wash and chop the broccoli florets into bite-sized pieces. If using frozen broccoli, no need to thaw—it can go straight into the slow cooker.
Dice the onion, mince the garlic, and shred the carrots.
2. Start Cooking the Base
In the bottom of your slow cooker, add the butter, onion, and garlic.
Add the flour (or cornstarch) and stir it with the butter mixture to create a light roux. This will help thicken the soup later.
3. Add Vegetables and Broth
Toss in the broccoli and carrots.
Pour in the chicken or vegetable broth.
Sprinkle in the smoked paprika, mustard powder, and a pinch of salt and pepper.
4. Cook Low and Slow
Cover the slow cooker and cook on low for 6 hours or high for 3–4 hours, until the vegetables are tender.
5. Add Cream and Cheese
Once the vegetables are soft, stir in the heavy cream.
Gradually add the shredded cheddar and Parmesan cheese, stirring until the cheeses are fully melted and incorporated.
6. Adjust Thickness
If the soup is too thick, add a splash of broth or milk until it reaches your desired consistency.
For a creamier texture, use an immersion blender to blend some (or all) of the soup until smooth. Leave some broccoli pieces intact for a chunkier soup if you prefer.
7. Season to Taste
Taste the soup and adjust the seasoning with additional salt, pepper, or spices as needed.
Serving Suggestions
Serve the soup warm with a sprinkle of shredded cheese on top and a handful of croutons for added crunch.
Pair it with crusty bread, garlic toast, or even a grilled cheese sandwich for the ultimate comfort meal.
Tips for the Perfect Broccoli & Cheese Soup
Use Freshly Grated Cheese: Pre-shredded cheese often contains anti-caking agents that can prevent it from melting smoothly. Grating your own cheese ensures a silky texture.
Don’t Skip the Roux: Adding flour or cornstarch in the beginning helps create a creamy base without relying entirely on heavy cream.
Customize the Veggies: Add cauliflower, celery, or potatoes for additional flavor and texture.
Storage: Leftovers can be stored in an airtight container in the fridge for up to 4 days. Reheat gently on the stove or in the microwave, adding a splash of milk or broth if needed.
