Preheat oven to 400-degrees F and line a large baking sheet with parchment paper or use a silicone baking mat. Set baking sheet aside.
In a large bowl, add all of the ingredients.
1 lb. ground chicken, 1 egg, ½ cup almond flour, ⅓ cup freshly grated parmesan cheese, ¼ cup grated yellow onion, 2 tbsp. extra-virgin olive oil, ½ tsp. fine sea salt, ⅛ tsp. ground pepper, 1 tsp. Italian seasoning , ½ tsp. garlic powder
Use a wooden spoon, or your hands, to fully mix ingredients together. But don't over mix - mix until just combined.
Roll mixture into balls, using about 2 tablespoons of ground chicken mixture per ball. I find it easiest to use a spring-loaded cookie scoop, but a spoon or measuring spoon also work.
Place meatballs on prepared baking sheet with a little bit of space between each meatball. Bake for 12-14 minutes until cooked through or until internal temperature reaches 165-degrees F.
Serve on their own, with pasta, or anyway you choose. Enjoy!
