Why This Recipe Slaps

This isn’t just another casserole. It’s a flavor bomb with minimal effort. Frozen meatballs?
Check. Jarred marinara? Check.
Cheese? Obviously. The magic happens when everything bakes together into a gooey, savory, carb-loaded masterpiece.
It’s kid-approved, adult-approved, and even picky-eater-approved. Plus, it’s customizable—swap ingredients, tweak the spices, or add veggies if you’re feeling ~fancy~. But let’s be real: the beauty is in its simplicity.
Ingredients
The Shortest Grocery List Ever)
- 1 lb frozen meatballs (or homemade if you’re extra)
- 24 oz marinara sauce (store-bought or your Nonna’s secret recipe)
- 2 cups shredded mozzarella (because more cheese = more happiness)
- 1 cup grated Parmesan (for that salty, nutty kick)
- 12 oz uncooked pasta (penne, rotini, or whatever’s lurking in your pantry)
- 2 cups water (yes, just water—this isn’t a chemistry experiment)
- 1 tsp garlic powder (optional, but highly recommended)
- 1 tsp Italian seasoning (or a sprinkle of dried oregano and basil)
Step-by-Step: How to Not Mess This Up

- Preheat your oven to 375°F. This isn’t a suggestion. Don’t skip it.
- Dump the dry pasta, meatballs, and marinara into a 9×13-inch baking dish.
Stir lightly—no need to overthink it.
- Pour water over everything. This keeps the pasta from turning into a crunchy disaster.
- Sprinkle garlic powder and Italian seasoning. Or don’t.
Live dangerously.
- Cover with foil and bake for 40 minutes. Set a timer so you don’t forget and binge Netflix instead.
- Remove foil, add cheeses, and bake uncovered for 10 more minutes. Cheese should be bubbly, not burnt.
- Let it sit for 5 minutes.
Unless you enjoy third-degree mouth burns.
Storage: Because Leftovers Are Life
Store leftovers in an airtight container in the fridge for up to 3 days. Reheat in the microwave (for speed) or oven (for crispiness). Want to freeze it?
Portion it out, wrap tightly, and freeze for up to 2 months. Thaw overnight in the fridge before reheating. Pro tip: Add a splash of water before reheating to revive the sauce.
Why This Recipe Wins at Life

- Time-saving: 10-minute prep, one-dish cleanup.
Mic drop.
- Budget-friendly: Uses pantry staples and frozen meatballs. No gourmet nonsense.
- Crowd-pleaser: Picky kids, hungry partners, and your carb-craving self will all agree.
- Versatile: Swap ingredients (see below) to keep it fresh.
Common Mistakes (Don’t Be That Person)
- Using cooked pasta: It’ll turn to mush. Uncooked pasta absorbs the sauce and water perfectly.
- Skipping the foil: Without it, the pasta won’t cook evenly.
Science, folks.
- Overloading on cheese: Okay, fine—this one’s negotiable.
Alternatives for the Adventurous (or Desperate)

- Meatballs: Swap for ground beef, sausage, or plant-based crumbles.
- Sauce: Use Alfredo, pesto, or a spicy arrabbiata for a twist.
- Pasta: Try gluten-free, whole wheat, or even cauliflower rice for a low-carb version.
- Cheese: Pepper Jack, provolone, or goat cheese can sub for mozzarella.
FAQs
Can I use fresh meatballs?
Absolutely. Just brown them first so they don’t turn into sad, greasy blobs.
Why is my pasta still hard?
You either didn’t add enough water or didn’t cover the dish. Fix it by adding a splash of water and baking longer.
Can I make this ahead?
Yep.
Assemble it (without baking), cover, and refrigerate for up to 24 hours. Add 5-10 minutes to the bake time.
Is this freezer-friendly?
Totally. Bake it, cool it, then freeze.
Reheat covered at 350°F until warmed through.
