Delightfully thick and creamy broccoli cauliflower cheese soup is packed with flavor and fresh veggies. This versatile soup recipe comes together in less than 30 minutes, perfect for any day of the week.
Say hello to the broccoli cheese soup of your dreams! This broccoli cauliflower cheese soup is a wholesome version of classic broccoli cheddar soup. It’s simultaneously ultra cheesy and creamy, yet nourishing and nutrient dense.
We were hoping for a “lighter” cheese soup and that’s where the veggies came to play. We also had both broccoli and cauliflower in the fridge needing to be used and thus broccoli cauliflower cheese soup was born.
This soup recipe is made with roasted veggies, broth, and shredded cheese, all blended together until smooth (the same method we use for loaded cauliflower potato soup).
The name says it all! This blended soup recipe is made with just a few fresh ingredients including:
- Broccoli + Cauliflower: Roasted broccoli and cauliflower florets are the base of this recipe. You’ll need 9 cups of total florets.
- Garlic: Along with the roasted veggies, we’ll roast whole garlic cloves for added flavor.
- Broth: Veggie broth thins out the soup.
- Cheese: Shredded white cheddar cheese keeps this soup creamy, adds a bit of protein, and is just all around delicious!
Try these ingredient variations:
To prevent grainy broccoli cheese soup:
- Roast veggies until fully cooked. Raw veggies don’t blend as smoothly as roasted, caramelized veggies.
- Use a high powered blender. A Vitamix (or food processor) will ensure that your soup is blended to perfection.
FAQ
To avoid curdling the cheese in this broccoli cauliflower cheese soup, make sure to follow the recipe instructions closely. Transfer everything to a blender instead of adding the cheese directly to the pot. By blending the soup ingredients, it removes the cheese from any direct heat and keeps the soup ultra smooth.
Yes! Omit the cheddar cheese in this recipe and make this vegan cheese sauce instead. Add the vegan cheese sauce to the blender at the same time you would have added the cheddar cheese. Still creamy and still delicious!
Like all soups, this broccoli cauliflower soup is great as leftovers. Store in an airtight container in the refrigerator for up to 5 days.
This soup is freezable, however, we suggest freezing it before adding in the cheese. When reheated, soups with dairy tend to be a little grainy. Transfer soup to freezer-safe containers for up to 3 months.
If you’ve already made the soup as-is (with the cheese), have no fear! Simply freeze the soup (here are all of our tips for how to freeze soup) and reheat on super low heat with a little extra broth.
Serving Suggestions
Broccoli cauliflower cheese soup is delicious with a thick slice of bread for dipping or alongside a hearty main dish like classic pot roast or baked lemon chicken. Top each bowl with freshly cracked black pepper, a sprinkle of shredded cheese, and a few roasted broccoli and cauliflower florets.
-
Preheat oven to 400ºF.
-
Place cauliflower, broccoli, and garlic cloves on a baking sheet. Drizzle 3 tablespoons of olive oil on top and toss so that the veggies are fully coated.
-
Roast veggies at 400ºF for about 20 minutes, or until the broccoli begins to brown.
-
While the veggies are roasting, sauté the yellow onion in about 1 tablespoon of olive oil with a pinch of salt. Once they are translucent, pour in the vegetable broth and let simmer for a few minutes.
-
Transfer all of the ingredients to a high-speed blender (including the cheese). If desired, set aside a couple roasted florets for topping.

Blend for about a minute, pureeing the vegetables and turning the mixture into a creamy soup.
- Storage: Store soup in an airtight container in the refrigerator for up to 5 days.
- Freezing Instructions: For best taste and texture, freeze this soup before adding in the cheese. When reheated, soups with dairy tend to be a little grainy. Transfer soup to freezer-safe containers for up to 3 months. If you’ve already made the soup as-is (with the cheese), simply freeze the soup, and reheat on super low heat with a little extra broth.
