Ingredients
- 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
Instructions
- 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.)
Air Fryer Instructions
- 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.
Baking Instructions
- Preheat the oven to 400°F. Line a baking sheet with parchment paper.
- Place the formed meatballs on the parchment lined baking sheet.
- Bake for about 15 minutes, or until almost or just barely cooked through (about 150°F internal temperature). Drain any extra liquid from the pan and wipe the edges of the meatballs if needed.
- Turn the oven to broil and move the oven rack right under the broiler. Place the meatballs under the broiler for about 2 minutes, until browned.
