Ingredients & Instructions
Below is everything you need to prepare this irresistible soup, along with extra tips to help you get the best results.
Ingredients
- 1 large head cauliflower, cut into florets
- 3 tablespoons olive oil, divided
- Salt and pepper, to taste
- 1 head garlic
- 1 medium yellow onion, diced
- 4 cups vegetable broth
- ½ teaspoon salt, plus more to taste
- Black pepper, to taste
- 1 heaping cup shredded sharp cheddar cheese
- Sliced green onion & extra cheddar (for garnish)
- Croutons or toasted sourdough bread
Step-by-Step Instructions
1. Roast the Cauliflower
Preheat your oven to 400°F (200°C) and line a baking sheet with parchment paper for easy cleanup. Spread the cauliflower florets on the baking sheet and drizzle with 1–2 tablespoons olive oil. Sprinkle with salt and pepper, then toss well to coat.
Roasting the cauliflower deepens its flavor, giving the soup that signature nuttiness.
2. Prepare the Garlic
Cut the top off the entire head of garlic, exposing the tops of the cloves. Drizzle with olive oil, wrap loosely in foil, and place it on the baking sheet with the cauliflower.
Roast everything until the cauliflower is deeply golden and the garlic cloves are soft and fragrant. Flip the cauliflower halfway through for even browning.
3. Sauté the Onion
Heat the remaining tablespoon of olive oil in a large pot over medium heat. Add the diced onion and cook until softened and lightly golden. This layer of flavor enhances the soup’s savory depth.
4. Blend the Soup
Carefully squeeze the roasted garlic cloves from their skins—they should slip out easily. Add the garlic to a blender along with the roasted cauliflower, sautéed onion, vegetable broth, salt, and pepper. Blend until the mixture becomes ultra smooth and creamy.
Tip: If your blender is small, blend in batches to avoid overflow.
5. Simmer & Add Cheddar
Pour the blended mixture back into your pot and bring to a gentle simmer. Add the shredded sharp cheddar cheese, stirring until melted and fully incorporated.
The cheese should melt smoothly—if the heat is too high, it may separate. A gentle simmer is key.
6. Taste & Serve
Taste the soup and adjust seasoning with more salt or pepper. Ladle into bowls and garnish with:
- Sliced green onions
- A sprinkle of extra cheddar
- Crispy croutons or a slice of toasted sourdough
This finishing touch adds texture and brightness to the creamy base.
Cooking Tips & Variations
1. Make It Extra Creamy
Add a splash of heavy cream or coconut milk before simmering for a richer, silkier texture.
2. Add More Veggies
Roast carrots, parsnips, or even potatoes along with the cauliflower for added flavor and thickness.
3. Try Different Cheeses
Swap cheddar for:
- Smoked gouda
- Gruyère
- White cheddar
Each brings its own unique depth.
4. Spice It Up
A pinch of cayenne, smoked paprika, or crushed red pepper flakes adds subtle heat that pairs beautifully with the roasted garlic.
5. Make It Vegan
Use:
- Olive oil instead of butter
- Vegan cheddar shreds
- Vegetable broth (already in the recipe)
The soup remains creamy thanks to the blended cauliflower.
