Ingredients for Creamy Roasted Cauliflower Soup
Gathering the ingredients for this delightful soup is simple! You’ll need: 1 head cauliflower, chopped into florets for that essential roasted flavor. We also need 1 whole head garlic; roasting it mellows its bite and adds a sweet, savory depth that’s key to why roast cauliflower for soup. You’ll also want 1 medium onion, diced, and 2–3 tbsp olive oil for roasting and sautéing. For the base, grab 4 cups vegetable or chicken broth. To make it wonderfully creamy without dairy, we’ll use 1–2 cups sharp cheddar cheese, shredded. Of course, season with salt and black pepper, to taste. For garnish, have green onions, sliced, and optional additions like croutons, toasted sourdough, parsley, or thyme. If you’re craving a richer soup, you can substitute some broth with milk or add a splash of heavy cream for a touch of ‘cauliflower soup with cream’ richness.

How to Make Creamy Roasted Cauliflower Soup
- Step 1: Let’s get started by preheating your oven to 400°F (200°C). This high heat is crucial for getting that lovely caramelization on our cauliflower.
- Step 2: Prepare the vegetables. Toss the cauliflower florets with 2–3 tbsp olive oil, salt, and black pepper right on your baking sheet. For the garlic, peel away the outer papery layers, slice about 1/4 inch off the top to expose the cloves, drizzle with a little more olive oil, and wrap the whole head tightly in foil.
- Step 3: Roast both the cauliflower and the foil-wrapped garlic until they are tender and nicely browned. This typically takes about 25–30 minutes. You’ll know the cauliflower is ready when it’s easily pierced with a fork, and the garlic will be soft and fragrant.
- Step 4: While your vegetables are roasting, heat a little olive oil in a large pot or Dutch oven over medium heat. Add the diced onion and sauté until it becomes soft and fragrant, about 5-7 minutes.
- Step 5: Once roasted, carefully unwrap the garlic. Squeeze the softened cloves out of their skins directly into a blender. Add the roasted cauliflower and the sautéed onions to the blender as well.
- Step 6: Pour in the 4 cups vegetable or chicken broth. If you have an immersion blender, you can skip transferring to a regular blender and blend everything right in the pot! Blend until the mixture is completely smooth and creamy. This is where the magic happens for our roasted cauliflower soup.
- Step 7: Pour the blended soup back into the pot and place it over medium heat. Stir in the 1–2 cups shredded sharp cheddar cheese.
- Step 8: Simmer the soup for about 10–15 minutes, stirring frequently, until the cheese is completely melted and the soup has a wonderfully rich and creamy consistency. This step truly elevates the flavor of this roasted cauliflower soup.
- Step 9: Taste and season with additional salt and black pepper as needed. Ladle the hot, creamy soup into bowls and serve immediately.

My favorite version, this creamy roasted cauliflower soup, gets its incredible flavor and texture from roasting the cauliflower and garlic before blending, making it a truly satisfying dish.

How do I make this soup vegan?
To transform this into a vegan creamy cauliflower soup, the key is to swap out the dairy ingredients. Use vegetable broth instead of chicken broth, and substitute the cheddar cheese with a good quality vegan cheddar cheese alternative. Some people also add a splash of unsweetened plant-based milk, like cashew or oat milk, for extra creaminess if the vegan cheese isn’t quite enough.
What makes this roasted cauliflower soup so rich without cream?
The magic behind this creamy roasted cauliflower soup‘s rich texture without using any actual cream lies in the roasting process and the cheese. Roasting the cauliflower caramelizes its natural sugars, creating a deeper, sweeter flavor and a softer texture that blends beautifully. The roasted garlic also contributes a wonderful depth. Then, melting in the sharp cheddar cheese emulsifies into the soup, creating that luxurious, velvety mouthfeel that feels so indulgent.
