How to make creamy cauliflower soup with Brussels sprouts

This simple recipe involves roasting the vegetables and then bringing everything together on the stove.

Step 1: Preheat the oven to 450°F.

Step 2: Place the cauliflower florets and Brussels sprouts in a large bowl. Add 3 tablespoons of olive oil and toss until evenly coated, then season with salt and pepper and toss again.

Step 3: Pour the vegetables onto a baking sheet and arrange so that the Brussels sprouts are cut-side down and the pieces aren’t touching.

Step 4: Place in the oven and roast, stirring after the 10-minute mark, until the vegetables are tender, about 15 minutes total. Remove from the oven.

Step 5: While the vegetables are roasting, heat a 3½ quart saucepan over medium heat and add the remaining 1 tablespoon olive oil.

Step 6: Add the onion and sauté until it’s translucent, then add the broth.

Step 7: Bring everything to a boil, then reduce the heat to low and simmer for about 10 minutes.

Step 8: Add two-thirds of the roasted vegetables to the saucepan and simmer for a few minutes, stirring occasionally. Remove from heat.

Step 9: Purée the soup either by using an immersion blender right in the pan or by transferring the mixture to a blender. Stir in the coconut milk and purée again if necessary.

Step 10: Pour into 4 serving bowls, garnish with remaining roasted vegetables, and serve immediately.

This soup is so rich and creamy, you’ll be amazed that it’s actually good for you!

Coconut or low-fat milk

If you make this recipe with coconut milk, it will be vegan, dairy-free, gluten-free, and paleo-friendly.

However, if you prefer not to eat the saturated fat found in coconut milk, you can substitute 1 cup of low-fat milk. This will reduce each serving to 228 calories, 16 grams of fat, and 3 grams of saturated fat.

Keep in mind that this will increase the cholesterol, sugar, and carbs slightly, and the soup will no longer be dairy-free or vegan.

Storage

This soup is best served immediately. However, if you do have leftovers, you can store them covered in the refrigerator for 3-4 days.

If possible, try to store the whole-roasted veggies separately so they don’t become soggy in the soup.
