How to Make Roasted Garlic Cheddar Cauliflower Soup Recipe
Step 1: Roast the Cauliflower and Garlic
Start by preheating your oven to 400°F. Arrange the cauliflower florets on a baking sheet and drizzle them with 1 tablespoon of olive oil to ensure they roast to a beautiful golden color. Next, take the head of garlic and slice off the top to expose the individual cloves, drizzle with a bit of olive oil, then wrap it tightly in foil. Pop both on the baking sheet into the oven and roast for 30 to 35 minutes. The cauliflower should be tender and caramelized, while the garlic becomes buttery soft, perfect for squeezing out its creamy goodness into the soup.
Step 2: Sauté the Onion and Celery
While the veggies roast, heat the remaining tablespoon of olive oil in a large pot over medium heat. Toss in the diced onion and chopped celery, sautéing them gently for about 5 to 6 minutes. This softens the vegetables and awakens their natural sweetness, which lays the flavor groundwork before the roasted stars join the mix.
Step 3: Combine and Simmer
Once the roasted cauliflower and softened garlic are ready, squeeze the garlic cloves out of their skins straight into the pot. Add the golden cauliflower florets, then pour in the broth. Bring this mixture to a boil, then lower the heat and let it simmer for 10 to 15 minutes so the flavors can marry and deepen. This simmering step enhances the richness and melds the roasted notes with the fresh sautéed base.
Step 4: Puree the Soup
Now for the magic moment—use an immersion blender right in the pot or transfer the soup in batches to a blender and puree until smooth and velvety. This step transforms the chunky veggies into a luscious, silky canvas ready for creamy indulgence.
Step 5: Add Milk and Cheese
Return the blended soup to low heat and stir in whole milk or half-and-half for that creamy texture. Sprinkle in the shredded sharp cheddar cheese and keep stirring until it melts completely, turning the soup irresistibly creamy and cheesy. Finish by adding smoked paprika along with salt and black pepper to taste. These seasonings add a delightful warmth and perfectly balance the cheese’s richness.
How to Serve Roasted Garlic Cheddar Cauliflower Soup Recipe

Garnishes
A final sprinkle of chopped chives or green onions brings a fresh pop of color and a mild oniony bite that brightens the soup perfectly. You can also add a swirl of cream or a few crispy croutons for some fun texture contrasts.
Side Dishes
This hearty soup pairs wonderfully with warm crusty bread, a simple green salad, or even a slice of garlic butter toast. The sides don’t have to compete; they just complement the soup’s robust, creamy flavors making your meal feel complete and satisfying.
Creative Ways to Present
For a special touch, serve the soup in mini bread bowls or garnish each bowl with a handful of toasted nuts like pecans or walnuts for crunch. You might also drizzle a bit of truffle oil or sprinkle some extra smoked paprika right before serving. These little flourishes turn an everyday comfort soup into something wonderfully memorable.
Make Ahead and Storage
Storing Leftovers
Will you have any leftovers? No worries! Store the soup in an airtight container in the refrigerator for up to 3 days. Just make sure to let it cool completely before sealing it to keep it fresh and flavorful.
Freezing
This Roasted Garlic Cheddar Cauliflower Soup Recipe freezes beautifully. Pour the cooled soup into freezer-safe containers or heavy-duty bags and freeze for up to 2 months. Keep in mind that the cheese may slightly separate when thawed but will still taste delicious.
Reheating
When ready to enjoy leftovers, reheat the soup gently on the stove over low heat, stirring frequently. Add a splash of milk or broth if it feels too thick. Reheating slowly helps maintain the creamy texture and ensures the flavors stay bright.
FAQs
Can I make this soup vegan?
Absolutely! Simply swap the cheddar cheese for your favorite vegan cheese and use plant-based milk and vegetable broth. Roasting the garlic and cauliflower remains the same for that rich, roasted flavor.
What if I don’t have an immersion blender?
No problem! You can carefully transfer the soup in batches to a regular blender. Just be cautious with the hot liquid and blend in smaller amounts to avoid spills.
Can I use fresh garlic instead of roasting a whole head?
You can, but roasting garlic mellows the flavor and adds a sweet, nutty depth that raw garlic cannot match. If you prefer fresh garlic, reduce the quantity and sauté it gently with the onion and celery to avoid harshness.
Is this soup gluten-free?
Yes, this recipe is naturally gluten-free as long as you use gluten-free broth and confirm your cheese is gluten-free. It’s perfect for those avoiding gluten but craving hearty comfort food.
How do I adjust the thickness of the soup?
If you want a thinner soup, just stir in additional broth or milk until it reaches your preferred consistency. For a thicker soup, use less broth or cook it down a bit longer before blending.
