Start by boiling your pasta until it is just about al dente. You are looking for a firm bite, as it will continue cooking in the oven. Drain it and give it a quick rinse under cold water to stop the cooking process. Do not skip this step or your pasta might end up mushy.
Grab that jar of marinara sauce and warm it up in a saucepan over medium heat until it is bubbly and fragrant. This will help the flavors pop and coat the meatballs better. Keep an eye on it; you want to avoid burning the bottom.
Gently stir in the frozen or homemade meatballs into that lovely marinara sauce. Make sure they are evenly coated; you want every bite packed with flavor. Be careful when mixing; if you are not gentle, those meatballs might fall apart.
Combine the cooked pasta with the meatball and sauce mixture in a baking dish. Stir it all together until everything is nicely coated. Do not skip this step, or you might find dry pockets in your pasta bake.
Sprinkle shredded mozzarella over the top of the pasta and meatballs, letting it cover everything generously. This gooey layer is where the magic happens, and you want it to melt beautifully. Do not forget to leave some cheese for extra browning at the end.
If you are feeling fancy, toss in some chopped fresh basil over the cheese for a touch of freshness and color. It will give your bake a delightful aroma as it cooks. Just a heads up, if you prefer less herby flavors, feel free to skip this.
Pop your dish into the oven and let it bake until everything is bubbly and the cheese is golden. This should take about 30 minutes. Keep an eye out towards the end; broil for a couple of minutes if you want that extra crispy cheese layer.
Before digging in, give the pasta bake a few minutes to cool off. This will help everything set and make serving easier. If you do not wait, your serving may fall apart, and we want it looking scrumptious!
