I smoked a big (and I do mean big) batch of meatballs the other day. I knew exactly what dish I was going to use them in first: baked spaghetti and meatballs. The idea just appealed to me. Easy, tasty, and pretty to boot. And like the big batch of meatballs, I knew I’d end up with a big batch of spaghetti, making for an easy week of meals. Score! You can use any meatballs you want. Frozen. Your mom’s favorite recipe. Anything.

Add More Stuff
I actually ended up doubling the sauce for this baked spaghetti and meatballs. I like my pasta saucy. And spicy, so I also added a healthy amount of red pepper flake. You could add other favorite ingredients as well. Mushrooms and bell peppers would be great.
I love making this dish in a cast iron skillet, even though I could really use a deep baking dish. I just like the extra ‘crust’ hot cast iron gives me.
If you’re using a store-bought marinara sauce, go for the more expensive bottle over the cheap stuff. It really makes a difference in this baked spaghetti and meatballs. The extra cost is well worth it in the end.
Also try my slow cooker spaghetti and meatballs.
