Step-by-Step Instructions
Prepare the Meatballs:
- Preheat your oven to 400°F (200°C). Line a baking sheet with parchment paper.
- In a large mixing bowl, combine the ground beef, almond flour, grated Parmesan cheese, egg, Italian seasoning, garlic powder, onion powder, salt, and pepper.
- Gently mix all ingredients together with your hands until just combined. Be careful not to overmix, as this can result in tough meatballs.
- Roll the mixture into approximately 1-inch meatballs. You should get about 20-24 meatballs.
- Place the meatballs on the prepared baking sheet and bake for 15-20 minutes, or until they are browned and cooked through.
Assemble the Casserole:
- While the meatballs are baking, pour the sugar-free marinara sauce into a 9×13 inch baking dish.
- Once the meatballs are cooked, carefully remove them from the oven and add them directly into the marinara sauce in the baking dish. Stir gently to coat the meatballs evenly.
- Sprinkle the shredded mozzarella cheese evenly over the meatballs and sauce.
- Return the baking dish to the oven and bake for another 10-15 minutes, or until the cheese is melted, bubbly, and lightly golden.
- Remove from the oven and let it rest for a few minutes before serving. Garnish with fresh chopped parsley, if desired.
