Servings4

1 medium head cauliflower, cut into florets
2 medium sweet potatoes, peeled and cubed into 1-inch pieces
1 tablespoon olive oil
1 teaspoon garlic powder
1 teaspoon smoked paprika
Salt and freshly ground black pepper, to taste
1 medium yellow onion, chopped
3 cloves garlic, minced
4 cups vegetable broth (low sodium preferred)
1 teaspoon dried thyme
1/2 teaspoon ground cumin
1/4 teaspoon ground nutmeg
1 tablespoon fresh lemon juice
Optional garnish
chopped fresh parsley, roasted pumpkin seeds

Instructions

Preheat your air fryer to 400°F (200°C).
In a large mixing bowl, toss the cauliflower florets and sweet potato cubes with olive oil, garlic powder, smoked paprika, salt, and pepper until evenly coated.
Place the seasoned vegetables in the air fryer basket in a single layer. Air fry for 20-25 minutes, shaking the basket halfway through, until the vegetables are tender and golden brown with crisp edges.
Meanwhile, heat a large pot over medium heat. Add a splash of olive oil and sauté the chopped onion until translucent, about 5 minutes.
Add the minced garlic, dried thyme, and ground cumin to the onions and cook for 1-2 minutes until fragrant.
Transfer the roasted cauliflower and sweet potatoes to the pot with the onion and garlic mixture.
Pour in the vegetable broth and stir in the ground nutmeg. Bring to a simmer and cook for 10 minutes to meld flavors.
Using an immersion blender, carefully blend the soup until smooth and creamy. Alternatively, blend in batches in a blender, handling hot liquids with care.
Stir in fresh lemon juice and adjust seasoning with salt and pepper to taste.
Serve hot, garnished with chopped fresh parsley and roasted pumpkin seeds if desired.
To store, cool the soup completely before transferring to airtight containers. Refrigerate for up to 4 days or freeze for up to 3 months. Reheat gently 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 Roasted Cauliflower and Sweet Potato 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.
