Ingredients

Here’s what you’ll need to whip up this magic. Most of these are probably already hanging out in your pantry and fridge!

  • 8 ounces spaghetti: You could really use any long pasta here, but classic spaghetti just feels right. Cook it until it’s just shy of al dente, because it’ll finish cooking in the oven.
  • 1 pound ground beef: I usually go for 85% or 90% lean, but use whatever you have on hand.
  • 1 onion, chopped: That essential aromatic base!
  • 2 cloves garlic, minced: Because what’s a pasta sauce without garlic?
  • 1 (28 ounce) can crushed tomatoes: This gives you a nice chunky sauce base.
  • 1 (15 ounce) can tomato sauce: Adds a smooth richness to the sauce.
  • 1 teaspoon dried oregano: Classic Italian herb flavor.
  • 1 teaspoon dried basil: Another must-have for that cozy pasta taste.
  • Salt and pepper to taste: Season generously as you go!
  • 2 cups shredded mozzarella cheese: For that glorious, bubbly, melty cheese pull on top!
  • 1/2 cup grated Parmesan cheese: Adds a salty, nutty depth of flavor. Freshly grated is always best if you have it!
  • 1/4 cup fresh parsley, chopped (for garnish): Optional, but it adds a lovely pop of color and freshness right before serving.

How to Make It

Alright, let’s get cooking! This comes together in just a few simple steps.

First things first, preheat your oven to 350°F (175°C). Get that oven nice and hot so your casserole bakes up perfectly golden and bubbly.

Next, grab your spaghetti. Cook it according to the package directions, but aim for al dente – meaning it still has a little bite to it. Since it’s going to bake in the oven, you don’t want to overcook it now. Once it’s done, drain it really, really well and set it aside. Soggy pasta is a no-go!

While the pasta is cooking (or just after), heat up a large skillet over medium heat. Add your ground beef, chopped onion, and minced garlic. Cook everything together, breaking up the meat with a spoon, until the beef is nicely browned and the onion is soft and translucent. This usually takes about 5-7 minutes. Once it’s cooked through, carefully drain off any excess grease. Nobody wants a greasy casserole!

Now, stir in the crushed tomatoes, tomato sauce, dried oregano, dried basil, salt, and pepper into the skillet with the meat. Give it a good stir to combine everything. Bring the sauce to a gentle simmer and let it cook for about 10 minutes, stirring occasionally. This helps those flavors meld together beautifully.

Time to combine! In a large bowl, gently add your cooked and drained spaghetti. Pour the delicious meat sauce over the top. Use tongs or two forks to gently toss everything together, making sure every strand of spaghetti is coated in that yummy sauce.

Grab a 9×13 inch baking dish and give it a light grease (cooking spray works great!). Scoop about half of your spaghetti and sauce mixture into the bottom of the dish, spreading it out evenly. Sprinkle half of that glorious shredded mozzarella cheese right over the top.

Now, add the remaining spaghetti mixture on top of the mozzarella layer. Spread it out again, then top the whole thing with the rest of the mozzarella cheese and all of the grated Parmesan cheese. Don’t be shy with that cheese!

Pop the baking dish into your preheated oven. Bake for 25-30 minutes, or until the cheese on top is completely melted, bubbly, and has turned a beautiful golden brown. That’s how you know it’s ready!

Once it’s out of the oven, let the casserole sit for 5-10 minutes before cutting into it. This helps it hold its shape a bit better. Just before serving, sprinkle some fresh chopped parsley over the top for a little brightness. Enjoy that first comforting bite!

Substitutions & Additions

This recipe is wonderfully forgiving and easy to customize! Here are a few ideas:

  • Meat Swap: Don’t have ground beef? Ground turkey or even Italian sausage (casings removed) work beautifully.
  • Add Veggies: Sauté some chopped bell peppers, mushrooms, or zucchini with the onion and garlic for extra nutrients and flavor.
  • Cheesy Variations: Mix up the cheese! Add some provolone, cheddar, or a blend of Italian cheeses along with or instead of the mozzarella and Parmesan. A sprinkle of red pepper flakes in the sauce adds a little heat if you like things spicy.
  • Different Sauce: If you’re in a hurry, you can totally use your favorite jarred marinara or pasta sauce instead of making it from scratch. Just simmer it with the cooked ground beef, onion, and garlic.

Tips for Success

Making this casserole is pretty foolproof, but here are a few things I’ve learned along the way to make it extra amazing:

  • Don’t Overcook the Pasta: I mentioned it before, but it’s worth repeating! Since the pasta bakes, cooking it al dente is key to avoid it getting mushy.
  • Drain the Grease: Make sure to drain off any excess fat after browning the meat and onions.
  • Season the Sauce: Taste your meat sauce before combining it with the pasta and adjust the salt and pepper as needed.
  • Let it Rest: Letting the casserole cool for a few minutes after baking helps it set up, making it much easier to scoop and serve without it turning into a pile of saucy noodles (though it’ll still taste great!).

How to Store It

Leftovers of this baked spaghetti casserole are fantastic! Let it cool completely, then cover the baking dish tightly with plastic wrap or foil, or transfer individual portions to airtight containers.

  • Refrigerator: Store in the fridge for 3-4 days.
  • Freezer: For longer storage, wrap the cooled casserole (either the whole dish or individual portions) very well in plastic wrap and then foil. It can be frozen for up to 2-3 months. Thaw overnight in the fridge before reheating.
  • Reheating: Reheat individual portions in the microwave. For larger amounts, cover the dish with foil and reheat in a 325°F (160°C) oven until heated through (timing will depend on the amount). You might need to add a splash of water or extra sauce if it seems dry.

FAQs

A few common questions I get about baked pasta:

Can I make this casserole ahead of time?

Absolutely! This is a great make-ahead meal. You can assemble the entire casserole in the baking dish (steps 1-7) but don’t bake it. Cover it tightly and store it in the refrigerator for up to 24 hours. When you’re ready to bake, let it sit at room temperature for about 15-20 minutes while the oven preheats, then bake as directed, adding an extra 5-10 minutes to the baking time if needed, to ensure it’s heated through the center.

What size baking dish do I need?

A standard 9×13 inch baking dish is perfect for this recipe.

Why did my casserole turn out dry?

This can happen for a few reasons! Ensure your pasta is cooked al dente (not too long) and drained well. Make sure you have enough sauce (the amounts in the recipe work well). Over-baking can also dry it out. If you’re worried, you can add a little extra tomato sauce or a splash of water when combining the pasta and sauce.

Notes

This casserole can be assembled up to 24 hours ahead and stored in the refrigerator; let it sit at room temperature for 15-20 minutes before baking and add 5-10 minutes to the baking time. Ensure pasta is cooked al dente and drained well to prevent a dry or mushy casserole. Drain excess grease after browning the meat. Taste and adjust sauce seasoning before combining with pasta.
