👩🍳 Step-by-Step Instructions
Step 1: Preheat Your Oven
Preheat oven to 375°F (190°C) . Grease a 9×13-inch baking dish lightly with non-stick spray or olive oil.
Step 2: Combine Sauce, Pasta & Seasoning
In a large mixing bowl:
- Toss together:
- Uncooked pasta
- Marinara sauce
- Water
- Garlic powder
- Onion powder
This allows the pasta to cook gently in the oven without boiling first.
Step 3: Add Frozen Meatballs
Stir in frozen meatballs so they’re evenly distributed throughout the mixture.
You can also layer them on top before baking if you prefer more defined meatball bites.
Step 4: Pour Into Baking Dish
Transfer the mixture into the prepared baking dish and spread out evenly.
Sprinkle with mozzarella cheese and finish with a generous dusting of Parmesan .
Step 5: Bake Until Golden & Bubbly
Cover with aluminum foil and bake at 375°F (190°C) for 30 minutes .
Remove foil and continue baking for 10–15 minutes longer, until the top is golden and bubbly.
Let sit for 5–10 minutes before serving — this helps everything set and makes slicing easier.
Step 6: Cool & Serve Warm
Cut into squares or scoop like lasagna — either way, it’s pure comfort food joy.
Serve hot with a sprinkle of fresh herbs or a side of garlic bread.
