This 5-ingredient oven chicken meatball bake is the kind of weeknight recipe that earns a permanent place in the dinner rotation because it asks for almost no prep while still delivering plenty of flavor. Using frozen chicken meatballs keeps things especially convenient, and a simple combination of pantry-style additions turns them into a saucy, satisfying casserole that feels far more cooked-from-scratch than the effort suggests.
Serve this over steamed white rice, buttered egg noodles, or mashed potatoes to catch every bit of sauce. It also pairs nicely with roasted broccoli, green beans, or a crisp salad on the side, and a piece of warm garlic bread makes it especially good for a cozy family supper.
5-Ingredient Oven Chicken Meatball Bake
Servings: 4 to 6
Ingredients
1 bag (24 to 26 ounces) frozen chicken meatballs
1 1/2 cups marinara sauce
1 cup shredded mozzarella cheese
1/2 cup grated Parmesan cheese
1 teaspoon Italian seasoning
Directions
1. Preheat the oven to 375°F and lightly grease a medium glass casserole dish if desired for easier cleanup.
2. Add the frozen chicken meatballs to the casserole dish and pour the marinara sauce over them. Sprinkle with the Italian seasoning, then stir gently so the meatballs are evenly coated.
3. Cover the dish loosely with foil and bake for 25 minutes, until the meatballs are hot and the sauce is bubbling around the edges.
4. Remove the foil, sprinkle the mozzarella and Parmesan evenly over the top, and return the dish to the oven for 10 to 15 minutes, until the cheese is melted and lightly golden.
5. Let the casserole rest for 5 minutes before serving so the sauce thickens slightly and the cheese settles. Spoon onto plates or into bowls and serve hot.
Variations & Tips
Use a different sauce: Marinara is an easy all-purpose choice, but this recipe also works well with vodka sauce, tomato-basil sauce, or even a light Alfredo if you want a creamier baked dish.
Add vegetables: For a more complete one-pan meal, scatter in sliced bell peppers, mushrooms, or baby spinach before baking. If using spinach, add it during the last 10 minutes so it stays bright and tender.
Make it heartier: Turn this into a casserole-style pasta bake by stirring in cooked penne or rotini before adding the cheese. You may want an extra splash of sauce so everything stays nicely coated.
Watch the salt level: Frozen meatballs, jarred sauce, and Parmesan can all bring salt to the dish, so taste the sauce combination before adding any extra seasoning beyond the Italian herbs.
Brown the top more deeply: If you like a darker, more bubbly cheese finish, place the casserole under the broiler for 1 to 2 minutes at the end, watching closely so the cheese does not scorch.
