Dump and Bake Meatball Casserole is a no-boil pasta dinner made with fully cooked meatballs, marinara, water, bowtie pasta, Italian seasoning, mozzarella, and Parmesan. The pasta cooks directly in the sauce and water, so there is no separate pot of boiling water to manage.
This casserole is especially useful on busy nights because the first stage is mostly hands-off. Once the pasta, sauce, water, seasoning, and thawed meatballs are combined, the dish bakes covered until the pasta softens. The cheeses go on only for the final part of baking.
Why This Dump-and-Bake Casserole Works
The 3 cups of water provide the liquid the dry bowtie pasta needs to cook in the oven, while a 24-ounce jar of marinara seasons that cooking liquid at the same time. Keeping the casserole tightly covered during the first 35 minutes traps steam and helps the pasta soften evenly.
Adding mozzarella and Parmesan after the pasta has cooked keeps the cheese from spending the full baking time in the oven. That gives you a melted, bubbly top instead of a dry cheese layer.

Ingredient Notes
Frozen meatballs: Use a 14-ounce bag of fully cooked frozen meatballs and thaw them before assembling the casserole. Starting with thawed meatballs helps them heat through at the same pace as the pasta.
Marinara or spaghetti sauce: A 24-ounce jar gives the pasta enough tomato sauce and seasoning while still leaving room for the added water the dry pasta needs.
Bowtie pasta: Use a 16-ounce box of dry farfalle or bowtie pasta. Do not boil it first. The pasta cooks in the covered casserole and absorbs the seasoned liquid as it bakes.
Mozzarella and Parmesan: These are added only after the first covered bake, then the casserole returns to the oven uncovered so the cheese can melt and bubble.
Ingredients
- 1 (14-ounce) bag fully cooked frozen meatballs, thawed
- 1 (24-ounce) jar marinara or spaghetti sauce
- 3 cups water
- 1 (16-ounce) box bowtie pasta, uncooked
- 1 teaspoon Italian seasoning
- 1 1/2 cups shredded mozzarella cheese
- 1/4 cup grated Parmesan cheese
How to Make Dump and Bake Meatball Casserole
- Preheat the oven to 400°F.
- Add the thawed meatballs, marinara sauce, water, dry bowtie pasta, and Italian seasoning to a high-sided oven-safe pot, deep skillet, or casserole dish.
- Stir well so the pasta is surrounded by liquid and sauce. Push down any pasta pieces that are sitting completely above the liquid.
- Cover the dish tightly with a lid or foil and bake for 35 minutes.
- Carefully remove the cover and stir. Check a piece of pasta for tenderness. If it is still quite firm, cover the dish again and bake for another 5 to 10 minutes before adding the cheese.
- Sprinkle the mozzarella and Parmesan evenly over the casserole.
- Return the dish to the oven uncovered and bake for another 10 to 15 minutes, or until the cheese is melted and the pasta is tender.
- Let the casserole rest for 10 minutes before serving. The sauce will thicken slightly as it stands.
Tips for No-Boil Pasta Casseroles
Cover the dish tightly. Steam is important when uncooked pasta is baking directly in sauce. A loose cover can let too much moisture escape before the noodles are tender.
Stir before baking. Dry pasta sticking out above the liquid may cook unevenly. Make sure the bowties are well coated before the dish goes into the oven.
Check pasta tenderness before serving. Different pasta brands can absorb liquid at slightly different rates. If the bowties are still too firm after the first bake, cover the dish and give them a little more time.
Use thawed, fully cooked meatballs. This keeps the timing predictable and prevents the casserole from depending on raw meat cooking safely at the same time as the pasta.
Easy Variations
Beef, turkey, chicken, or Italian-style fully cooked meatballs can all work. Keep the meatball package close to the same 14-ounce amount so the casserole maintains a similar sauce-to-pasta ratio.
You can also use another short pasta shape such as rotini, penne, or small shells. Because shapes vary in thickness, use the pasta tenderness test rather than relying only on the clock.
Storage and Reheating
Store leftovers in an airtight container in the refrigerator for up to 3 to 4 days. Pasta continues absorbing sauce during storage, so add a spoonful of marinara or a small splash of water before reheating if the casserole looks dry.
Individual portions can be reheated in the microwave. For a larger amount, cover the casserole and warm it in the oven until the center is hot, then uncover for the last few minutes if you want the cheese on top to soften again.
Frequently Asked Questions
Do I boil the pasta first?
No. The bowtie pasta goes into the casserole dry and cooks in the marinara and water while the dish is covered.
Can I use frozen meatballs without thawing them?
For the most reliable timing, thaw the fully cooked meatballs first. That way the meatballs heat through while the pasta cooks without forcing you to extend the baking time too much.
Why is my pasta still firm?
The most common causes are a loose cover, pasta sitting above the liquid, or a pasta brand that needs a little longer. Stir, make sure the noodles are coated, cover tightly, and bake for another 5 to 10 minutes before adding the cheese.
