Servings4

1 medium head cauliflower, cut into bite-sized florets
2 medium leeks, white and light green parts only, sliced and separated
1 tablespoon olive oil
1 teaspoon sea salt
1/2 teaspoon freshly ground black pepper
1 teaspoon garlic powder
4 cups vegetable broth (gluten-free if preferred)
1 cup unsweetened coconut milk or other dairy-free milk
1 tablespoon nutritional yeast (optional, for a subtle cheesy flavor)
1 teaspoon dried thyme
1/2 teaspoon smoked paprika
Fresh chives or parsley, finely chopped, for garnish

Instructions

Preheat your air fryer to 400°F (200°C) for 3-5 minutes.
In a large bowl, toss the cauliflower florets and sliced leeks with olive oil, sea salt, black pepper, and garlic powder until evenly coated.
Spread the cauliflower and leeks in a single layer in the air fryer basket. Roast for 12-15 minutes, shaking or stirring halfway through, until the vegetables are tender and lightly caramelized.
While the vegetables roast, heat the vegetable broth in a large pot over medium heat.
Once roasted, carefully transfer the cauliflower and leeks into the hot broth. Bring the mixture to a gentle simmer.
Add dried thyme, smoked paprika, and nutritional yeast (if using) to the pot. Stir well and let simmer for 5 minutes to allow flavors to meld.
Remove the pot from heat. Using an immersion blender, carefully puree the soup until smooth and creamy. Alternatively, transfer the soup in batches to a blender, puree until smooth, then return to the pot.
Stir in the dairy-free milk until fully incorporated. Taste and adjust seasoning with additional salt or pepper if needed.
Ladle the soup into bowls and garnish with freshly chopped chives or parsley before serving.
To freeze, cool the soup completely and store in airtight containers for up to 3 months. Reheat gently on the stove or microwave before serving.

Recipe guidance

Crispiness Control

Pat the head cauliflower dry, avoid crowding, and use only a light coat of oil or sauce before cooking. Add wet sauces near the end when you want the outside to stay crisp.

Storage

Store leftover Air Fryer One-Pot Creamy Cauliflower and Leek Soup in an airtight container in the refrigerator for up to 3 days. Cool the food before sealing so excess steam does not soften the texture.
