This turkey meatball casserole combines the best of Italian comfort food with lean protein for a family-friendly dinner that's both satisfying and simple. The juicy turkey meatballs nestled in marinara sauce and blanketed with gooey cheese create a dish that promises empty plates and requests for seconds.
I first created this casserole during a busy sports season when my family needed hearty meals that could be prepped ahead. Now it's requested so often I keep ground turkey in the freezer specifically for this recipe.
Ingredients
- Ground turkey: Provides lean protein with less fat than beef while remaining juicy and flavorful
- Italian breadcrumbs: Add texture and help bind the meatballs without making them dense
- Parmesan cheese: Brings nutty depth to both the meatballs and topping
- Egg: Acts as the crucial binder that keeps your meatballs from falling apart
- Garlic and onion powder: Infuse flavor without the work of chopping fresh aromatics
- Marinara sauce: Creates the flavorful base; choose a high-quality jar or make homemade for best results
- Mozzarella cheese: Melts into a golden bubbly blanket that makes this casserole irresistible
- Fresh parsley: Brightens the finished dish with color and fresh flavor
Step-by-Step Instructions
- Prepare the Oven:
- Preheat your oven to 375°F to ensure it reaches the perfect temperature for melting cheese while fully cooking the meatballs. This moderate heat allows everything to cook evenly without burning the cheese.
- Mix the Meatballs:
- Combine ground turkey with breadcrumbs, Parmesan, egg, and seasonings using clean hands to gently incorporate everything. The key is mixing until just combined; avoid overworking the meat which can make tough meatballs.
- Form and Brown:
- Use a cookie scoop or tablespoon to create uniform meatballs about 1½ inches in diameter. Consistent sizing ensures they cook evenly. Brown them in a lightly oiled skillet, turning gently until they develop a golden crust which seals in moisture and creates flavor.
- Assemble the Casserole:
- Spread a thin layer of marinara in your casserole dish, which prevents sticking and adds flavor to the bottom of each meatball. Arrange the browned meatballs in a single layer, then pour remaining sauce over them ensuring each meatball is nestled in sauce.
- Add the Cheese Layer:
- Sprinkle mozzarella and Parmesan cheeses evenly over the entire casserole, creating a generous layer that will melt into golden perfection. The two cheeses create the perfect balance of melt and flavor.
- Bake to Perfection:
- Bake for 25 to 30 minutes until the cheese becomes bubbly and slightly golden and meatballs reach 165°F internally. The sauce should be bubbling around the edges signaling it has reduced slightly and concentrated in flavor.
- Rest and Garnish:
- Allow the casserole to rest for 5 minutes before serving which helps the cheese set slightly and makes serving easier. Sprinkle with fresh parsley just before bringing to the table for a pop of color and fresh flavor.

The Italian breadcrumbs are my secret weapon in this recipe. My grandmother taught me that they not only help bind the meatballs but also gently absorb some of the natural juices keeping everything moist. Her original recipe used veal but I adapted it for turkey when my husband was watching his cholesterol.
Make-Ahead Instructions
This casserole is perfect for busy households. You can prepare the entire dish up to the baking step, cover tightly with foil, and refrigerate for up to 24 hours. When ready to cook, simply add an extra 5 to 10 minutes to the baking time since you'll be starting with cold ingredients. The meatballs themselves can also be formed up to 2 days ahead and stored in the refrigerator which makes assembly lightning fast.
Creative Variations
Transform this basic recipe with simple twists that create entirely new meals. Try using ground chicken instead of turkey for an even lighter option. For a Mediterranean version, add diced roasted red peppers, feta cheese, and oregano to the meatball mixture. You can also create a Mexican-inspired version using taco seasoning in the meatballs, topped with enchilada sauce and Mexican cheese blend instead of marinara and mozzarella.

Serving Suggestions
While pasta is the traditional pairing, this casserole is remarkably versatile. Serve over creamy polenta for an elevated comfort meal or with crusty garlic bread for soaking up the flavorful sauce. For a lighter option, place the casserole alongside a crisp green salad dressed with lemon vinaigrette which cuts through the richness perfectly. If you have leftovers, split some crusty rolls, stuff with meatballs and extra cheese, then broil briefly for quick meatball subs the next day.
Storage and Reheating
This casserole stores beautifully, making it perfect for meal prep. Refrigerate leftovers in an airtight container for up to 3 days. For freezing, portion the cooled casserole into individual servings and store in freezer-safe containers for up to 3 months. Thaw overnight in the refrigerator and reheat in a 350°F oven until warmed through, about 15 to 20 minutes. You can also microwave individual portions but cover with a damp paper towel to prevent the meatballs from drying out.
