• Egg – Binds the meatball mixture; another added to coat spaghetti.
• Garlic Powder – Enhances meaty flavor; fresh garlic is a great alternative if preferred.
For the Casserole

Step‑by‑Step Instructions for Spaghetti and Meatball Casserole
Step 1: Preheat and Prepare
Begin by preheating your oven to 400°F (200°C). While it heats, lightly oil a 9×13 inch baking dish to prevent sticking. Gathering all your ingredients now will make the process smoother, ensuring you have everything ready for assembling your irresistible spaghetti and meatball casserole.
Step 2: Make the Meatballs
In a sizable mixing bowl, combine the ground beef, bread crumbs, milk, salt, Worcestershire sauce, black pepper, minced onion, parsley, one egg, and garlic powder. Use your hands to mix gently until just combined, then form this mixture into 1-inch meatballs. These should be placed on a parchment-lined baking sheet before baking.
Step 3: Bake the Meatballs
Transfer the meatballs to your preheated oven and bake them for about 18-20 minutes. You’ll know they’re ready when they are browned and cooked through, reaching an internal temperature of 160°F (70°C). Once done, take them out and reduce the oven temperature to 350°F (175°C) for later.
Step 4: Cook the Spaghetti
Bring a large pot of salted water to a boil, and cook your spaghetti until it’s just al dente, about 1-2 minutes less than the package suggests. Drain the spaghetti and drizzle with olive oil to prevent sticking. This step ensures that your pasta holds up well when combined with the other ingredients later.
Step 5: Mix the Spaghetti with Cheese
In a separate bowl, whisk together a second egg, minced parsley, shredded mozzarella, freshly grated Parmesan, and black pepper. Once mixed, add this mixture to your drained spaghetti and toss everything together until the pasta is evenly coated, adding a creamy richness to your dish.
Step 6: Layer the Casserole
In your prepared baking dish, begin layering by spreading half of the cheesy spaghetti mixture evenly at the bottom. Place the freshly cooked meatballs on top of the pasta, followed by pouring the pasta sauce over everything. Cover the dish with foil to trap in moisture during the initial baking.
Step 7: Bake the Casserole
Bake the covered casserole in the 350°F (175°C) oven for about 35 minutes. This helps the flavors meld beautifully and ensures the pasta absorbs the delicious sauce. After this time, you can remove the foil, revealing the tantalizing layer of noodles and meatballs.
Step 8: Add More Cheese and Finish Baking
Sprinkle any remaining mozzarella and Parmesan cheese over the top of your casserole, then return it to the oven uncovered. Bake for an additional 10 minutes, or until the cheese is bubbly and golden brown. The transform will draw everyone to the table with its delightful aroma.
Step 9: Let it Rest
Once your spaghetti and meatball casserole is done baking, remove it from the oven and let it rest for about 5 minutes. This resting period gives the layers time to set and makes serving much easier. Enjoy the comforting dish that showcases love and family in every bite!

How to Store and Freeze Spaghetti and Meatball Casserole
Fridge: Store leftovers in an airtight container for up to 4 days. Let them cool completely before sealing to maintain quality.

Reheating: When ready to enjoy, thaw overnight in the fridge. Reheat in the oven at 350°F (175°C) for about 25-30 minutes, or until heated through. Microwave is also an option, but oven-reheating will keep the spaghetti and meatball casserole’s texture intact.
Make-Ahead: You can prepare the casserole up to a day in advance, cover, and store in the fridge before baking, simplifying busy weeknight dinners!

Expert Tips for Spaghetti and Meatball Casserole
-
Perfect Meatballs: Cook them just until browned; they will continue cooking in the oven. Overcooking now can lead to dry meatballs in your casserole.
-
Al Dente Spaghetti: Always cook pasta until just al dente. It won’t soften further in the oven, ensuring your spaghetti has the perfect texture.

Olive Oil Coating: Don’t skip coating the drained spaghetti with olive oil. This step prevents clumping and ensures an even mixture with the egg and cheese.
-
Moisture Control: Cover the casserole with foil during the first phase of baking. This keeps moisture in and prevents the top from drying out before the inside heats through.
-
Cheese Variety: Feel free to experiment with different cheeses on top, like gouda or cheddar, to create a unique twist on your spaghetti and meatball casserole.

Spaghetti and Meatball Casserole Recipe FAQs
How do I choose the best ground beef for meatballs?
Absolutely! For the juiciest meatballs, I recommend using ground beef with a fat content of 80/20 or 85/15. This allows for moisture while still providing enough flavor and texture. If you prefer a lighter option, ground turkey or a blend of beef and pork also works wonderfully!
How can I store leftovers of this casserole?
Very simply! Store any leftover spaghetti and meatball casserole in an airtight container in the refrigerator for up to 4 days. Be sure to let it cool completely before sealing it to keep the flavors fresh. If you have more than you can eat, you might want to consider freezing it!
Can I freeze spaghetti and meatball casserole?
Absolutely! This casserole freezes well both before and after baking. For freezing, cover it tightly with foil or place it in a sealed container. You can keep it in the freezer for up to 3 months. When you’re ready to bake it, thaw overnight in the refrigerator before reheating.
What if my meatballs are tough?
If you find your meatballs are tough, it might be due to overmixing or using too lean of meat. To avoid this, mix the ingredients gently until just combined, and consider using a meat blend with a bit more fat. Also, remember not to overcook them in the oven; they should be slightly underdone before baking in the casserole for the best texture!
Are there any dietary considerations for this casserole?
Yes, indeed! If you have any gluten sensitivities, you can substitute regular spaghetti with gluten-free pasta without compromising taste. For dairy-free options, use dairy alternatives for milk and shredded cheese. Always check ingredient labels for any potential allergens, especially in sauces and pre-packaged ingredients!
