Tender past noodles, rich tomato sauce, hearty ground beef, and tons of cheese make this casserole comforting and filling.

With a baked spaghetti casserole, you take advantage of combining the sauce and the noodles in the casserole dish, so it is easier to make than you might think.

Even better, is when the spaghetti sauce and cheese sauce melt together into the noodles.

How to make Baked Spaghetti

1. Make the Sauce: In a large pot or large skillet, brown the beef, onion, and bell pepper over medium-high heat until no longer pink. Add the garlic, spices, tomatoes, and sauce. Bring to a boil and reduce to a simmer for 30 minutes.
2. Prepare the Cheese Mixture: In a large bowl, combine the ricotta cheese, parmesan cheese, and egg. Mix to combine and season with salt and black pepper if desired.

3. Cook the Spaghetti: Bring a large pot of water to a boil. Salt the water and add the spaghetti noodles. Cook the spaghetti to al dente (according to package directions) and drain. Do not rinse. Combine the cooked spaghetti with the meat sauce reserving 2 cups of sauce.

4. Assemble the Casserole: Preheat oven to 375F. In a deep 9×13 oven safebaking dish, add 1 cup of spaghetti sauce to bottom of baking dish and spread. Place 1/3 of the spaghetti mixture in the bottom in an even layer. Add 1/2 the cheese mixture and spread in an even layer.
5. Bake: Add another 1/3 of the spaghetti mixture and top with the remaining ricotta mixture. Top with remaining spaghetti. Pour remaining 1 cup sauce over the top. Top with mozzarella cheese and bake 30 minutes or until bubbly and the cheese is golden brown. Remove from the oven and let rest 5 minutes.

• ​Garlic knots
• Italian chopped salad
• Green beans
• Caesar salad

How long does it last?

You can store any leftovers in an airtight container in the fridge for a few days. Reheat in the microwave or oven until warmed through.

Add a little extra sauce if it starts to dry out.

Can I freeze it?

It makes a great freezer meal the whole family can enjoy on a busy weeknight. Freeze the casserole before or after baking for up to 3 months.

If baking it ahead of time, cool or bring to room temperature before freezing. Thaw overnight in the fridge and bake or reheat until warmed through.

I recommend freezing it in easy to retrieve portion sizes too so you don’t have to heat it all up if you just need enough to serve one or two.

How long do you bake spaghetti?

Since you under-cook the spaghetti in the first place, count on the extra baking time in the casserole dish to finish cooking the spaghetti.

Typically the bake time for a spaghetti casserole runs about 25-30 minutes depending on your oven.

Since you are starting with al dente spaghetti, which is just slightly undercooked intentionally, the time in the oven sets the texture of the noodles perfectly.

Do you cover baked spaghetti?

To prevent too much moisture from escaping, and to help seal in the flavors even more, covering the spaghetti casserole with aluminum foil for the first 20 minutes of cooking time is a good idea. This helps to keep it from drying out.

When you pull the foil off, then you can add a bit more cheese mixture if you want, but the goal now is letting the cheese bubble and melt and form a bit of a crust over the top.

When the cheese looks nice and melted, with a few browner spots and crusting at the edges, you have achieved spaghetti casserole perfection!

Best Casserole Tips

• To avoid the pasta from becoming mushy, undercook it by a few minutes so it is still firm. Then add to the casserole. It will continue to cook while baking.
• For cheese that melts the best, shred it yourself from a block.
• Make your own Italian seasoning with spices like basil, parsley, oregano, thyme, sometimes sage, cilantro, and red pepper flakes.
• Don’t like ricotta cheese? Use cream cheese or cottage cheese.
• This will be a favorite so make a double batch and freeze one for later.
• Spray the bottom of your casserole with a cooking oil spray like avocado or olive oil.
