What You’ll Need
You only need a few everyday ingredients to make this soup taste exceptional.
For Roasting:
- 1 large head cauliflower, cut into florets
- 1 whole garlic bulb
- 2 tablespoons olive oil
- Salt and black pepper, to taste
For the Soup Base:
- 2 tablespoons butter
- 1 medium onion, diced
- 4 cups low-sodium chicken broth (or vegetable broth for vegetarian)
- 1 cup milk or half-and-half
- 1 1/2 cups shredded sharp cheddar cheese
- 1/4 cup grated Parmesan cheese (optional, for extra depth)
- 1/4 teaspoon smoked paprika
- Salt and pepper, to taste
For Garnish (Optional):
- Extra shredded cheddar
- Chopped chives or green onions
- Crumbled bacon
- Toasted cauliflower florets or croutons
Step-by-Step Instructions
Step 1: Roast the Cauliflower and Garlic
Preheat your oven to 400°F (200°C). Line a baking sheet with parchment paper for easy cleanup.
Arrange the cauliflower florets on one side of the pan. Drizzle with 1 tablespoon of olive oil and season with salt and pepper.
Slice the top off the garlic bulb to expose the cloves. Drizzle with the remaining olive oil, wrap in foil, and place it on the baking sheet next to the cauliflower.
Roast for 25–30 minutes, stirring the cauliflower halfway through, until golden brown and tender. The garlic should be soft and caramelized.
Once done, let them cool slightly. Squeeze the roasted garlic cloves from their skins and set aside.
Step 2: Sauté the Onion
In a large soup pot or Dutch oven, melt the butter over medium heat.
Add the diced onion and cook for 5–6 minutes until softened and translucent.
Stir in the roasted garlic and cook for another minute until fragrant.
Step 3: Add the Cauliflower and Broth
Add the roasted cauliflower to the pot along with the chicken or vegetable broth.
Bring to a gentle simmer and cook for 10 minutes to allow the flavors to blend.
Step 4: Blend Until Smooth
Using an immersion blender, puree the soup until completely smooth and creamy.
Alternatively, you can transfer the soup to a blender in batches — just be sure to vent the lid slightly to release steam.
If the soup is too thick, add a little more broth or milk until you reach your desired consistency.
Step 5: Add Cheese and Seasonings
Return the pureed soup to low heat. Stir in the milk or half-and-half, followed by the shredded cheddar and Parmesan cheese.
Keep stirring until the cheese melts and the soup becomes velvety and smooth. Do not boil — gentle heat is best to prevent curdling.
Add smoked paprika, salt, and pepper to taste. Adjust seasoning as needed.
Step 6: Serve and Garnish
Ladle the soup into bowls and top with your favorite garnishes — extra shredded cheddar, crumbled bacon, or a sprinkle of chives all add a perfect finishing touch.
Serve warm with crusty bread, gluten-free rolls, or a fresh green salad.
Tips for Perfect Roasted Garlic Cheddar Cauliflower Soup
- Roast the garlic low and slow.
This brings out its natural sweetness and deep flavor — it’s what gives the soup its gourmet edge. - Use sharp cheddar.
It adds a strong, tangy flavor that balances the mild cauliflower perfectly. - Blend thoroughly.
A smooth texture makes all the difference. If using a blender, blend in batches until silky. - Don’t overheat after adding cheese.
Keep the heat low to prevent the cheese from separating. - Season in stages.
Taste after blending and again after adding cheese to balance saltiness and flavor depth.
Flavor Variations
Once you’ve mastered the base recipe, try these easy twists:
Savory Add-Ins
Broccoli-Cauliflower Blend:
Add 1 cup of steamed broccoli before blending for a more colorful, hearty soup.
Bacon Cheddar Version:
Add crispy bacon pieces right into the soup for extra smoky richness.
Spicy Kick:
Stir in a pinch of cayenne pepper or red pepper flakes for a little heat.
Caramelized Onion Twist:
Use caramelized onions instead of sautéed ones for a sweeter, more complex flavor.
Lighter or Dairy-Free Versions
Dairy-Free Option:
Use plant-based milk and dairy-free cheddar. Add a tablespoon of nutritional yeast for cheesy flavor.
Low-Calorie Version:

Serving Suggestions
This soup pairs beautifully with:
- Crusty bread or gluten-free rolls
- Grilled cheese or panini sandwiches
- Side salad with lemon vinaigrette

It’s hearty enough to enjoy on its own but also elegant enough to serve as a starter for special dinners.

How to Store and Reheat
Refrigerator:
Store cooled soup in an airtight container for up to 4 days.
Reheat gently on the stove over low heat, stirring occasionally.
Freezer:
Freeze in portioned containers for up to 2 months.
Thaw overnight in the refrigerator before reheating.
Add a splash of broth or milk while reheating to restore creaminess.
Make-Ahead Option
You can roast the cauliflower and garlic a day ahead and store them in the fridge until you’re ready to make the soup.
When ready, just sauté the onion, add the roasted vegetables and broth, and proceed with blending and finishing. This makes dinner prep effortless and quick.
Troubleshooting
Soup too thick:
Add more broth or milk until it reaches your desired consistency.
Soup too thin:
Let it simmer uncovered for a few minutes to reduce and thicken naturally.
Cheese clumping or curdling:
Avoid boiling after adding cheese; stir gently over low heat.
Not enough flavor:
Add a touch more roasted garlic, extra cheddar, or a pinch of smoked paprika.
