1 tablespoon olive oil

¼ teaspoon black pepper

½ teaspoon onion powder
¼ teaspoon paprika

Optional Toppings

Instructions

Step 1: Prepare the Cauliflower

Wash and cut the cauliflower into bite-sized florets. Pat dry thoroughly with paper towels to remove excess moisture.

Step 2: Pre-Cook the Cauliflower

In a bowl, toss cauliflower with olive oil, salt, and pepper.

Preheat the air fryer to 375°F (190°C) for 3 minutes. Air fry the cauliflower for 8–10 minutes until slightly tender and lightly golden.

Step 3: Make the Cheese Sauce

In a saucepan over medium heat, melt butter and cream cheese together until smooth. Stir in heavy cream, garlic powder, onion powder, and paprika.

Add cheddar and mozzarella cheese gradually, stirring constantly until melted and creamy.

Step 4: Combine

Transfer the cooked cauliflower into a mixing bowl and pour the cheese sauce over the top. Toss gently until fully coated.

Step 5: Air Fry the Mac and Cheese

Spoon the mixture into a greased air-fryer-safe baking dish. Sprinkle extra cheddar cheese or crushed pork rinds on top if desired.

Air fry at 360°F (182°C) for 6–8 minutes until bubbly and golden on top.

Step 6: Serve

Allow the dish to cool slightly before serving. Garnish with bacon or parsley if desired.

Tips for Best Results

Dry the cauliflower well to prevent watery cheese sauce.
Avoid overcooking the cauliflower during the first air fry stage.
Use freshly shredded cheese for smoother melting and better texture.
Add bacon or jalapeños for extra flavor and richness.
Crushed pork rinds make a great keto crunchy topping.
For a thicker sauce, simmer the cream mixture slightly longer before adding cheese.
Reheat leftovers in the air fryer at 350°F for 3–5 minutes until hot and bubbly.
