In a large bowl, combine beef, almond flour, parmesan, egg, and spices. Mix gently.
Form the mixture into 1-inch meatballs using a cookie scoop.
Preheat air fryer to 375°F (190°C) and spray the basket.
Arrange meatballs in a single layer in the basket.
Air fry for 10-12 minutes, shaking halfway through.
Serve with warm sugar-free marinara.
Notes
For a change of pace, try these meatballs with our Keto Meatballs Recipe on the stovetop. Leftovers can be stored for 4 days and are perfect for lunch boxes. If your air fryer is small, cook in two batches to ensure maximum crispiness.
