How to Make Meatball Parmesan Casserole
-
Preheat the oven: Start by preheating your oven to 400°F (200°C). This step is crucial to ensure that your casserole bakes evenly and achieves that delightful golden finish.
-
Mix ingredients: In a large mixing bowl, combine ground turkey, egg, shredded mozzarella, and your chosen seasonings. Stir gently until everything is just incorporated without overmixing, which helps keep your meatballs tender.
-
Form meatballs: Shape the mixture into 1.5-inch meatballs and place them on a parchment-lined baking sheet. Uniformity in size will help them cook evenly, giving you perfectly tender bites.
-
Bake meatballs: Pop those meatballs into the oven and bake for 25 minutes, or until they’re cooked through and golden brown. The aroma will start to fill your kitchen, making it hard to resist!
-
Assemble the casserole: In a casserole dish, layer your baked meatballs, generously pouring over the low-carb tomato sauce, followed by more mozzarella and a sprinkle of parmesan. This layering creates a gooey, cheesy masterpiece.
-
Bake again: Bake the casserole uncovered for 15-20 minutes. You want to wait until the cheese is melted and bubbly. For an extra crispy top, broil for 2-3 minutes, keeping an eye to avoid burning.
-
Rest and garnish: Let the casserole rest for about 5 minutes before serving. This lets the flavors meld together beautifully. Garnish with fresh basil or parsley for a pop of color and freshness.
Optional: Serve alongside a crisp green salad for a well-rounded meal.
