Preheat your oven to 400°F (200°C). Line a baking sheet with parchment paper or lightly grease it.
In a large mixing bowl, combine the ground beef, Parmesan cheese, almond flour, eggs, minced garlic, oregano, salt, and black pepper. Mix well until all ingredients are combined.
Scoop out the mixture and form it into meatballs, about 1 to 1.5 inches in diameter. Arrange the meatballs on the prepared baking sheet.
Bake in the preheated oven for about 15-20 minutes or until the meatballs are cooked through and reach an internal temperature of 160°F (70°C).
While the meatballs are baking, melt the butter in a large skillet over medium heat. Add minced garlic and sauté for 1-2 minutes until fragrant.
Once the meatballs are done, transfer them to the skillet with the garlic butter and toss to coat evenly. Cook for an additional 1-2 minutes to allow the flavors to meld.
Serve the meatballs hot, garnished with chopped parsley.
