Spaghetti and Meatball Pasta Bake

Baked Spaghetti and Meatballs

Classic spaghetti and meatballs gets a twist with this Baked Spaghetti and Meatballs, topped with lots of mozzarella cheese.

I found myself with some extra frozen Italian meatballs after making this Easy Italian Meatball Soup last week, so I thought a feed of spaghetti and meatballs was in order.

Rather than just enjoy them the classic way, I cooked up this Spaghetti and Meatball Pasta bake by pouring it all into my cast iron skillet and baking it up with a generous topping of mozzarella cheese. It’s a really simple recipe, but it was easy and delicious, so I thought I’d share it.

I am a big fan of the edge of crispy pasta bits that baking pasta creates, yet underneath and inside, is lovely soft and saucy pasta, to give a nod to the classic, as well.

Make this one even easier by using a good quality, store-bought marinara sauce to start. Simply upscale it a bit with some fresh, sauteed garlic and onion. Throw in a few red pepper flakes, if you like a touch of warmth.

Cook’s Notes for Baked Spaghetti and Meatballs

I used my stash of homemade marinara sauce, that I made this past Summer and froze. If you have some too, this is a perfect use for it. Otherwise, there are a number of nice jarred store-bought marinara sauces available now. You’ll need about 4 cups.

As noted above, I used leftover frozen, store-bought Italian meatballs. You can also buy fresh, store bought Italian meatballs, or make your own and then quickly pre-cook them in a skillet while your pasta water is coming to a boil (or cook them up further ahead and refrigerate).

Be sure to undercook your spaghetti ever so slightly, about 2 minutes less that the package recommends.

If you don’t have a large ovenproof skillet, you can just mix it all up in a bowl (sauce and pasta) and pour into a casserole instead.

Leftovers keeps well in the fridge and reheat nicely. I find reheating in the microwave in a covered dish helps preserve the moisture in the pasta.
