To make this irresistible spaghetti and meatball casserole, you will need a mix of fresh pantry staples. The quality of your meat and sauce directly impacts the final dish, so reach for high-quality ground beef and a premium marinara to ensure a rich, deep flavor profile that tastes like it simmered all day.

• 1.25 lb ground beef (80/20 Chuck)
• 1/2 cup bread crumbs
• 2 tbsp milk
• 3/4 tsp salt
• 1.5 tsp Worcestershire sauce
• 1/2 tsp pepper
• 1/4 cup onion, finely minced
• 2 tbsp parsley
• 1 egg + 1 extra for coating
• 1/2 tsp garlic powder
• 8 oz spaghetti
• 1 tbsp olive oil
• 28 oz pasta sauce (Rao’s recommended)
• 1.75 cups mozzarella cheese (shredded from a block)
• 3/4 cup mozzarella (separate for coating)
• 1/2 cup parmesan cheese (freshly grated)

Keep these tips in mind to get the best results when creating this irresistible spaghetti and meatball casserole at home.

• If you prefer, you can use ground turkey or a beef-and-lamb blend for lighter meatballs.
• Always use freshly shredded mozzarella, as it melts significantly better than pre-bagged versions.
• Finely mincing the onions is key to keeping the texture smooth and ensuring the meat binds properly.
• Ensure you cook the pasta al dente; it will continue to soften as it absorbs the sauce in the oven.
• For a boost of fresh flavor, substitute dried parsley with double the amount of fresh flat-leaf parsley.

Step 1: Prepare Mise en Place and Preheat

Preheat your oven to 400°F and lightly oil a 9×13 inch baking dish. Finely mince your onion into tiny 1/8-inch pieces, which allows them to disappear into the meat mixture. Having your ingredients prepped and ready before you start ensures a seamless workflow.

Step 2: Mix and Bake the Meatballs

In a large bowl, combine the beef, bread crumbs, milk, salt, Worcestershire, pepper, onion, parsley, egg, and garlic powder. Mix by hand until just combined, then roll into 1-inch balls. Place them in your prepared baking dish and bake at 400°F for 18-20 minutes. Remove them when finished and lower the oven temperature to 350°F.

Step 3: Cook the Pasta

Boil your spaghetti in salted water until just al dente, about 1-2 minutes under the package time. Drain well and toss with olive oil to prevent the noodles from sticking together while you finish the assembly.

Step 4: Create the Cheese and Egg Mixture

In a small dish, whisk together the second egg, parsley, 3/4 cup mozzarella, 1/2 cup parmesan, and pepper. This mixture creates a creamy, cheesy base that coats the pasta perfectly, ensuring every bite is rich and flavorful.

Step 5: Assemble the Casserole Base

Toss the pre-cooked pasta with the cheese and egg mixture. Transfer this into the baking dish used for the meatballs. Add the meatballs and the marinara sauce, stirring gently to combine all ingredients without crushing the meatballs.

Step 6: Bake Covered and Finish with Cheese

Cover your dish tightly with foil and bake at 350°F for 35 minutes. Carefully remove the foil, top with the remaining 1.75 cups of mozzarella and the extra parmesan, and return to the oven uncovered for 10 minutes until bubbly and golden.

Step 7: Rest and Serve

Let the dish rest for at least 5 minutes before serving. This allows the sauce to thicken and the cheese to set, making it much easier to scoop into satisfying portions.

This irresistible spaghetti and meatball casserole is a complete meal, but it pairs beautifully with fresh sides to cut through the richness of the cheese and sauce.

• Serve with a crisp side salad featuring a light balsamic vinaigrette.
• Add warm, buttery garlic bread for dipping into the extra marinara.
• Prepare a side of steamed broccoli or roasted asparagus for a pop of freshness.
• Pair with a refreshing glass of sparkling citrus water or iced tea.

Store any leftovers in an airtight container in the refrigerator for up to 3 days. To reheat, place a portion in an oven-safe dish with a splash of water, cover, and bake at 350°F until heated through, or warm gently in the microwave at 50% power to ensure the pasta stays moist.

Can I make this recipe ahead of time?

Yes, you can assemble the casserole up to the point of baking, store it in the fridge, and bring it to room temperature before popping it in the oven. This makes it an ideal preparation for busy weeknights.

Can I freeze this recipe?

You can freeze the assembled casserole before the final bake. Wrap it securely in multiple layers of foil and plastic wrap, and thaw it in the refrigerator overnight before continuing with the baking instructions.

What can I serve with this recipe?

A simple green garden salad with Italian dressing is the perfect side to balance the hearty nature of this pasta bake. Garlic bread also makes for a wonderful addition for soaking up any remaining sauce.

How do I keep this recipe from drying out?

The key is to keep the casserole covered with foil for the first 35 minutes of baking, which traps the steam. Additionally, ensure your pasta is slightly al dente so it absorbs the sauce rather than losing its structure.

Cook Mode Prevent your screen from going dark

Instructions

Preheat your oven to 375°F (190°C).
Cook the spaghetti in boiling salted water for 1-2 minutes less than the package directs for al dente, then drain.
In a large bowl, mix the ground beef, bread crumbs, milk, salt, Worcestershire sauce, pepper, minced onion, parsley, 1 egg, and garlic powder until combined.
Form the mixture into bite-sized meatballs.
Heat olive oil in a skillet and brown the meatballs on all sides, then set aside.
In a bowl, beat the remaining egg; toss the cooked spaghetti with the egg to coat.
Spread a thin layer of sauce in a baking dish, add the pasta, meatballs, and the remaining sauce.
Top with mozzarella and parmesan cheese.
Cover with foil and bake for 45 minutes; remove foil and bake for another 20 minutes until the cheese is bubbling and golden.

Notes

Use freshly grated mozzarella from a block for the best melt quality. You can customize the dish by adding Italian herbs like oregano or basil to the meatball mixture. Ensure the pasta is slightly undercooked when boiling, as it will continue to absorb liquid from the sauce while baking.
