Preheat the oven to 400°F and line a rimmed baking sheet with parchment.
Combine the beef, pork, almond flour, Parmesan, egg, garlic, parsley, Italian seasoning, salt, and pepper in a large bowl.
Mix gently with your hands just until evenly combined; do not compact the meat.
Shape the mixture into 24 meatballs, about 1 1/2 inches each, and arrange them on the baking sheet.
Bake for 18 to 20 minutes, until browned and the centers reach 160°F.
Rest for 5 minutes before serving or adding the meatballs to sauce.
