Preheat your oven to 400°F (200°C) and line a baking sheet with parchment paper for easy cleanup.
In a large bowl, combine the ground beef, almond flour, egg, minced garlic, onion powder, Italian seasoning, salt, pepper, and grated Parmesan cheese. Use your hands to mix everything until just combined. Be careful not to overmix.
Using your hands, shape the mixture into meatballs, about 1.5 inches in diameter. Place them evenly spaced on the prepared baking sheet.
Bake the meatballs in the preheated oven for 15-20 minutes or until they are browned and cooked through (internal temperature should reach 160°F or 70°C).
While the meatballs are baking, melt the butter in a saucepan over medium heat. Add 3 cloves of minced garlic to the melted butter and sauté for 1-2 minutes until fragrant. Be careful not to burn the garlic.
Once the meatballs are cooked, remove them from the oven and drizzle the garlic butter over the top. You can also toss the meatballs in the sauce for a more even coating.
Sprinkle fresh parsley over the meatballs for color and flavor before serving.
Notes
Serve the meatballs on a platter, drizzled with extra garlic butter and garnished with sprigs of parsley. Pair them with sautéed zucchini noodles for a complete meal.
