1. Crank your oven to 375°F and let it preheat while you get everything ready.
2. Grab a 9×13-inch baking dish and dump those frozen meatballs straight in. No need to thaw—that’s what makes this so easy.
3. Pour the entire jar of marinara sauce over the meatballs, making sure they’re all covered. Use a spoon to spread it around if needed.
4. Sprinkle the Parmesan cheese evenly over everything, then add the oregano, garlic powder, salt, and pepper. Don’t be shy with the seasonings—frozen food can handle bold flavors.
5. Cover the dish tightly with foil and slide it into the oven. Bake for 25 minutes covered—this helps everything heat through evenly.
6. Pull off that foil and bake for another 10 minutes uncovered. You want the sauce bubbling and the cheese getting slightly golden and maybe a little crispy on top.
7. Remove from the oven and let it sit for 2-3 minutes. The sauce is molten hot straight from the oven, trust me on this.
8. Tear up fresh basil leaves and scatter them over the top right before serving. This makes it look and taste like you put way more effort in than you actually did.
9. Serve hot over pasta, in sub rolls, or straight from the dish with crusty bread. However you serve these, they’ll disappear fast.

Notes:

• No need to thaw the meatballs first. Frozen works perfectly.
• If your oven runs cool, you might need an extra 5-10 minutes of covered baking time.
• The cheese on top should get golden and slightly crispy—that’s the best part.
• Every brand of frozen meatballs is sized differently, so cooking times might vary slightly.
• Don’t skip the fresh basil garnish—it really makes the dish.

Storage Tips:

Store leftovers in an airtight container in the fridge for up to 4 days. Reheat in the microwave or on the stovetop with a splash of water. These freeze beautifully—portion into containers and freeze for up to 3 months. Thaw overnight in the fridge and reheat gently. They actually taste even better the next day after flavors meld.
