- Large mixing bowl: For combining all the meatball ingredients.

Low-Carb Cheesy Meatball Casserole Made Stepwise

Step 1: Preheat the Oven
Begin by preheating your oven to 375°F (190°C). This ensures that your casserole bakes evenly.
Step 2: Prepare the Meatball Mixture
In a large mixing bowl, combine the 2 pounds of ground turkey or chicken, 1 cup of freshly grated Parmesan cheese, 2 eggs, 1/4 cup of grated onion, 3 minced garlic cloves, 2 tablespoons of chopped parsley, 2 teaspoons of Italian seasoning, 1 teaspoon of ground black pepper, and 1/2 teaspoon of crushed red pepper flakes. Season with kosher salt to taste. Mix everything together until well combined, but be careful not to overmix.
Step 3: Form the Meatballs
Using your hands, shape the mixture into meatballs, about 1-2 inches in diameter. Place them on a baking sheet lined with parchment paper for easy cleanup.
Step 4: Bake the Meatballs
Bake the meatballs in the preheated oven for about 20 minutes or until they are cooked through and golden brown. This initial baking step helps to keep them juicy when added to the casserole.
Step 5: Prepare the Casserole
While the meatballs are baking, spread 24 ounces of low-carb marinara sauce evenly in the bottom of your baking dish.
Step 6: Layer the Meatballs
Once the meatballs are ready, remove them from the oven and place them on top of the marinara sauce in the baking dish.
Step 7: Add the Ricotta
Dollop 1/2 cup of ricotta cheese over the meatballs, distributing it evenly for creaminess throughout the dish.
Step 8: Top with Mozzarella
Sprinkle 1/2 cup of shredded mozzarella cheese over the ricotta layer. This will melt beautifully and create a delicious cheesy topping.
Step 9: Bake the Casserole
Return the assembled casserole to the oven and bake for an additional 20-25 minutes or until the cheese is bubbly and golden brown.
Step 10: Garnish and Serve
Once it’s done, take the casserole out of the oven and let it cool for a few minutes. Garnish with 3 tablespoons of freshly chopped basil before serving.
If You’re Out Of…

- Ground turkey or chicken: Use lean ground beef or pork as an alternative.
- Parmesan cheese: Grated Pecorino Romano cheese works well.
