Ingredients & Instructions
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 and extra cheddar for topping
- Croutons or toasted sourdough bread, optional
Step-by-Step Instructions
1. Roast the Cauliflower
Preheat your oven to 400°F (200°C) and line a baking sheet with parchment. Spread the cauliflower florets evenly, drizzle with 1–2 tablespoons olive oil, and season generously with salt and pepper. Toss to coat.
Roasting the cauliflower brings out a deep, caramelized sweetness that gives this soup its signature flavor. Be sure not to overcrowd the tray—space lets the florets brown instead of steam.
2. Prep and Roast the Garlic
Take a whole head of garlic and trim off the top just enough to expose the cloves. Place it on a small square of foil, drizzle with a bit of olive oil, and wrap it loosely. Set it beside the cauliflower on the baking sheet.
As it roasts, the garlic becomes soft, buttery, and mild—perfect for blending into the soup without raw garlic sharpness.
3. Sauté the Onion
While the vegetables roast, heat the remaining 1 tablespoon olive oil in a pot over medium heat. Add the diced onion and sauté until soft and translucent.
This forms the aromatic base of your soup and adds a subtle sweetness that complements the roasted vegetables.
4. Blend Everything Smooth
Once the cauliflower is golden and the garlic cloves are soft enough to squeeze out of their skins, transfer them to a blender. Add the sautéed onion, vegetable broth, salt, and pepper.
Blend until completely smooth and creamy. If your blender is small, blend in batches or use an immersion blender right in the pot.
Tip: For an ultra-silky texture, blend longer than you think you need to—about 60–90 seconds.
5. Heat and Add the Cheese
Pour the blended mixture back into your pot and bring it to a gentle simmer. Add the shredded sharp cheddar cheese and stir until fully melted.
The sharp cheddar deepens the flavor while giving the soup its creamy richness. If you enjoy a strong cheese flavor, feel free to add a bit more.
6. Taste and Adjust
Season with extra salt and pepper as needed. Cauliflower is mild and can absorb seasoning, so be sure to taste and adjust until the flavors pop.
7. Serve with Your Favorite Toppings
Ladle the soup into bowls and garnish with:
- Sliced green onion
- Extra cheddar cheese
- Crunchy croutons or toasted sourdough
The toppings add texture, color, and contrast—turning a simple bowl of soup into a full, delicious experience.
Cooking Tips & Variations
1. Add Depth with Herbs
A sprig of thyme, a bay leaf, or even a pinch of smoked paprika during simmering can add wonderful warmth and complexity.
2. Make It Extra Creamy
For a richer texture, stir in a splash of half-and-half, cream, or coconut milk after blending.
3. Add Protein
A cup of white beans blended into the soup adds body and protein without affecting the flavor.
4. Make It Spicy
Stir in a pinch of red pepper flakes, or top with a drizzle of chili crisp.
5. Try Different Cheeses
Swap cheddar for:
- Gouda
- Gruyère
- Parmesan
- Pepper Jack
Each creates a slightly different but equally delicious flavor.
6. Make It Vegan
Use vegetable broth and substitute the cheddar for a good-quality vegan cheese that melts well. Add a tablespoon of nutritional yeast for cheesy depth.
Storage & Serving Suggestions
Storage
- Refrigerator: Keep in an airtight container for up to 4 days.
- Freezer: Freeze for up to 3 months. Thaw overnight and reheat gently on the stove.
Reheating Tips
Warm over medium heat, stirring often. If it thickens, add a splash of broth or water to loosen the texture.
Serving Ideas
This soup pairs perfectly with:
- Grilled cheese sandwiches
- Simple green salads
- Roasted vegetables
- Crusty artisan bread
It makes a great starter but is hearty enough to be the main course when topped generously.
