Roasted Cauliflower Soup Recipe
Here’s the full journey-from raw florets to a smooth, luscious bowl of comfort. I’ll walk you through each step as though we’re cooking together in the same kitchen.
Ingredients Needed
To make a creamy, flavorful roasted cauliflower soup, gather the following:
- 1 medium head of cauliflower – cut into florets
- 2 tablespoons olive oil – for roasting; feel free to use avocado oil for a higher smoke point
- 1 medium onion – roughly chopped
- 2 cloves garlic – minced
- 4 cups vegetable or chicken broth – use low-sodium for better control over seasoning
- 1 cup unsweetened plant-based milk or cream – optional, for added creaminess
- Salt and pepper – to taste
- 1/2 teaspoon smoked paprika or cumin – optional, adds subtle depth
- Fresh herbs for garnish – parsley, chives, or thyme work beautifully
- Optional toppings – croutons, toasted seeds, or a drizzle of olive oil
Cooking Instructions
Let’s break this down step by step:
-
Preheat The Oven
- Set your oven to 425°F (220°C). This high heat helps achieve golden, caramelized edges on the cauliflower.
-
Roast The Cauliflower
- Toss florets in olive oil, salt, pepper, and optional smoked paprika.
- Spread on a baking sheet in a single layer.
- Roast for 25-30 minutes, stirring halfway through for even browning.
-
Sauté The Aromatics
- While the cauliflower roasts, heat a splash of olive oil in a large pot over medium heat.
- Sauté onions until translucent and slightly golden.
- Add garlic and cook for another 1-2 minutes until fragrant.
-
Combine And Simmer
- Add roasted cauliflower to the pot.
- Pour in broth and bring to a gentle boil. Reduce heat and simmer for 10-15 minutes, letting the flavors meld.
-
Blend To Perfection
- Use an immersion blender or transfer soup in batches to a regular blender.
- Blend until silky smooth. Add milk or cream at this stage if desired, adjusting for richness.
-
Season And Serve
- Taste and tweak seasoning with salt, pepper, or extra herbs.
- Ladle into bowls and garnish with your favorite toppings.
Ingredient Insights
-
Cauliflower
- A cruciferous superstar, full of fiber, vitamins C and K, and antioxidants. Roasting it develops a nutty, caramelized flavor profile that boiling just can’t achieve.
-
Olive Oil
- Helps the florets caramelize and adds a subtle fruity richness.
-
Onions And Garlic
- The backbone of flavor-softened onions provide sweetness, garlic adds aromatic depth.
-
Broth
- Acts as the liquid base, giving the soup body and umami richness. Using homemade or high-quality store-bought broth elevates the flavor significantly.
-
Milk Or Cream
- Optional but recommended for a silky mouthfeel. Plant-based milk keeps it vegan while cream adds decadence.
Expert Tips
- Roasting matters: Don’t rush it! The deeper the caramelization, the more complex your soup will taste.
- Don’t skip seasoning: Even a creamy soup needs layers of seasoning throughout, not just at the end.
- Texture control: For chunkier soup, blend partially; for smooth, blend completely.
- Make ahead: Soup tastes even better the next day as flavors meld. Reheat gently to avoid breaking the creaminess.
Recipe Variations
- Spicy Roasted Cauliflower Soup: Add red pepper flakes or a splash of sriracha.
- Cheesy Twist: Stir in grated Parmesan or a sharp cheddar for a richer flavor.
- Herb-forward: Blend in fresh basil, tarragon, or dill for a vibrant twist.
- Nutty Boost: Garnish with toasted almonds, pine nuts, or pumpkin seeds.
- Curried Version: Add a teaspoon of curry powder while sautéing onions for a warming, exotic flavor.
