How to Make Roasted Garlic Cheddar Cauliflower Soup Recipe
Step 1: Roast the Cauliflower and Garlic to Perfection
Preheat your oven to 400°F. Line a baking sheet with parchment paper for easy cleanup. Toss the cauliflower florets on the sheet with 1-2 tablespoons of olive oil, then season generously with salt and pepper. Here’s a trick I’ve learned: don’t skimp on salt during roasting; it really brings out the flavors. Now for the garlic—cut about ¼ inch off the top of the whole head so the tops of the cloves peek through, drizzle with olive oil, and wrap it loosely in foil. Place both the cauliflower and garlic on the sheet and roast for 30 to 35 minutes, flipping the cauliflower halfway through. You’ll know it’s ready when the cauliflower is golden and caramelized and the garlic feels soft.
Step 2: Sauté the Onion Base
While the roasting is happening, heat a tablespoon of olive oil in a large pot over medium heat. Add your diced yellow onion and cook for about 5 to 8 minutes until translucent and fragrant. This step builds the foundation of flavor for the soup, and doing it slowly lets the onions release their sweetness without browning.
Step 3: Blend Soup Ingredients Until Velvety Smooth
Once the cauliflower and garlic have cooled enough to handle—don’t rush this or you’ll burn your fingers—squeeze the soft roasted garlic cloves out of their skins. Into your blender, add the sautéed onion, roasted cauliflower, the squeezed garlic, broth, salt, and pepper. Blend until silky smooth, about a minute. I like using a high-powered blender for this, but a regular blender will work if you blend in batches.
Step 4: Melt in the Cheddar and Simmer
Pour the blended soup back into your pot and warm over medium heat until it starts to simmer gently. Then, stir in your shredded sharp cheddar cheese a handful at a time until melted and fully incorporated. This is where that velvety texture and zingy cheesy flavor come alive! Let it simmer for another 10-15 minutes to deepen the flavors, then taste and adjust salt and pepper as needed.
Pro Tips for Making Roasted Garlic Cheddar Cauliflower Soup Recipe
- Roasting Trick: Don’t rush flipping the cauliflower—letting each side get a nice brown crust adds great depth of flavor.
- Garlic Handling: Let the roasted garlic cool fully before squeezing out the cloves to avoid bitterness and burns.
- Cheese Choice: Use a sharp or extra-sharp cheddar for best results—milder cheeses won’t give you that punchy flavor.
- Blending Safety: When blending hot soup, vent your blender lid or blend in short bursts to avoid pressure build-up.
How to Serve Roasted Garlic Cheddar Cauliflower Soup Recipe
Garnishes
I’m a sucker for a little extra texture and freshness, so I always top my soup with thinly sliced green onions and a handful of extra sharp cheddar cheese. If I’m serving company, a sprinkle of crispy bacon bits or a little smoked paprika can be a fun surprise, too.
Side Dishes
This soup loves crusty bread—whether it’s toasted sourdough, a multi-grain baguette, or even garlic bread on the side. I also sometimes pair it with a simple green salad dressed with a zesty vinaigrette to balance out the richness.
Creative Ways to Present
For holiday dinners or when I’m hosting, I like to serve this soup in little mini soup crocks or even hollowed-out mini pumpkins for that wow factor. You can also drizzle a swirl of chili oil or herb-infused olive oil on top for a gourmet touch that’s surprisingly easy.
Make Ahead and Storage
Storing Leftovers
After enjoying my soup, I let leftovers cool completely before transferring them to airtight containers. They store beautifully in the fridge for up to 4 days. I’ve found that the flavors actually deepen overnight, so it tastes even better the next day!
Freezing
This soup freezes really well, which is a lifesaver when I make a big batch. Just cool it, pour into freezer-safe containers (leaving some headspace for expansion), and freeze for up to 3 months. When you thaw it, you might notice the texture has shifted slightly, but a good stir or quick blend fixes that in a flash.
Reheating
I reheat the soup gently on the stove over medium-low heat, stirring frequently so the cheese doesn’t separate or scorch on the bottom. Adding a splash of broth or milk while reheating can help keep it creamy and smooth.
FAQs
-
Can I make this Roasted Garlic Cheddar Cauliflower Soup Recipe without cheese?
Absolutely! If you’re avoiding dairy, you can omit the cheddar cheese and boost flavor by adding nutritional yeast or a splash of coconut milk for creaminess. Roasted garlic and cauliflower still deliver plenty of flavor on their own.
-
How do I get the best roasted garlic flavor for this soup?
Roasting whole heads of garlic with the skins still on and a drizzle of olive oil is key. Don’t peel the individual cloves before roasting—this keeps garlic creamy and mellow. After roasting, squeeze the softened cloves out, which adds a subtle sweetness contrasting the cheddar beautifully.
-
Can I use frozen cauliflower instead of fresh?
You can, but fresh cauliflower gives a better texture and flavor when roasted. If you opt for frozen, thaw and pat dry well, then roast it a bit longer to get some caramelization, which helps mimic that fresh-roasted taste.
-
Is this soup gluten-free?
The soup itself is naturally gluten-free if you skip croutons or use gluten-free bread for dipping. Always double-check your broth and cheese ingredients just to be sure.
Final Thoughts
I absolutely love how this Roasted Garlic Cheddar Cauliflower Soup Recipe turns out every single time—rich, comforting, and just the right balance of cheesy and savory. When I first tried roasting the garlic along with the cauliflower, it completely transformed the soup for me, so I’m excited to share that little trick with you. Whether you need a tasty meal to cozy up with on a chilly night or a crowd-pleaser for friends and family, this soup has got your back. Give it a go—you might just find your new favorite soup!

- 3 tablespoons olive oil, divided
- Freshly ground salt and pepper, to taste
- 1 head garlic
- 1 medium yellow onion, diced

To Garnish

Instructions
- Preheat Oven: Preheat your oven to 400°F and line a baking sheet with parchment paper to prepare for roasting.
- Roast Cauliflower and Garlic: Toss cauliflower florets with 1-2 tablespoons olive oil, generously season with salt and pepper, and spread on the baking sheet. Peel the outer layers of the whole garlic head, leaving cloves intact, then cut ¼ inch off the top to expose cloves. Drizzle garlic with olive oil, wrap loosely in foil, and place on the baking sheet with cauliflower. Roast for 30-35 minutes, flipping halfway through, until golden and caramelized.
- Sauté Onion: While roasting, heat 1 tablespoon olive oil in a pot over medium heat. Add diced onion and sauté for 5-8 minutes until translucent and fragrant.
- Blend the Soup: Once roasted, allow the garlic to cool slightly, then squeeze the softened garlic cloves out of their skins. In a large blender, combine the sautéed onion, roasted cauliflower, garlic, broth, salt, and pepper. Blend until smooth, approximately 1 minute, then transfer back to the pot.
- Simmer and Add Cheese: Heat the blended soup over medium heat, bringing it to a gentle simmer. Stir in shredded cheddar cheese until melted and incorporated. Simmer for an additional 10-15 minutes to meld flavors. Taste and adjust seasonings if necessary.
- Serve and Garnish: Ladle soup into bowls and garnish with sliced green onions and extra cheddar cheese. Serve alongside croutons, toasted sourdough, or your preferred bread for dipping.
Notes
- For creamier soup, substitute 1 cup of the broth with milk.
- For a richer texture, replace ½ cup of broth with half-and-half or heavy cream.
- You can use chicken broth if not keeping the soup vegetarian.
- Ensure garlic is cooled before squeezing to avoid burns.
