1/ Preheat the Arena:
2/ Start off by firing up your oven to 425°F.
3// Mix it Up:
4/ Grab a 9 x 13-inch baking dish. Toss in the rotini pasta, marinara sauce, water, and those adorable little meatballs. Want a little extra flavor? A pinch of salt won’t hurt. Give it all a good stir.
5/ / Bake Time:
6/ Cover the dish snugly with aluminum foil. Slide it into the oven and forget about it for 35 minutes. Well, don’t completely forget—set a timer!
7/ Peek and Stir:
8/ After the timer goes off, uncover the dish. Stir things around and take a moment to taste the pasta. Not quite al dente? Cover it back up and let it cook a bit more.
9/ The Cheesy Finale:
10/ Once the pasta has achieved its ideal texture, blanket the casserole with shredded mozzarella. Pop it back into the oven, this time uncovered, for an extra 5-10 minutes, until the cheese is gloriously melted.
