Air Fryer Meatballs

Dish Info

Caramelized Onion Meatballs are simple to prepare and deliver an unexpected richness of flavors. The caramelized onion gives them a real boost in texture and taste, while fresh herbs keep the flavors bright and fresh. I like to make them in the air fryer, but these delicious keto meatballs can be baked as well.


– ¼ cup olive oil divided into 2 tablespoons and 2 tablespoons – 1 ¾ cups onion (6 ounces)sliced into thin quarter moons – 1 pound ground beef – ¼ cup blanched almond flour 1 ounce – 1 large egg – 1 teaspoon chopped fresh rosemary – 1 teaspoon chopped fresh sage – 1 teaspoon fresh thyme chopped – 1 teaspoon sea salt – ¼ teaspoon black pepper

– Preheat either your oven or air fryer. (Instructions below.) – In a medium skillet, heat 2 tablespoons of oil over medium heat. Add the sliced onions and cook for at least 20 minutes, until the onions are caramelized and their volume has reduced to about ½ cup. Set aside to cool.

– Meanwhile, in a large bowl, combine the ground beef, almond flour, egg, rosemary, sage, thyme, sea salt, black pepper, and remaining 2 tablespoons oil. Mix until just combined.

– When the onions are warm but no longer hot, fold them into the meat until just mixed in. Do not overmix.

– Using a medium cookie scoop to scoop the meat mixture, gently form balls with your fingertips. (You can also use rounded spoonfuls, 1 ½ to 2 tablespoons in size.)

– Set your air fryer to 400°F.

– Spray the meatballs and cook for 5 minutes. Flip and cook for 4 to 7 minutes longer. Remove from the air fryer when the internal temperature is about 160 degrees. Rest for 5 minutes and serve.
