Easy Dump & Bake Meatball Casserole (Small Batch, No‑Boil Pasta)

 

Cooking for one or two doesn’t have to mean settling for bland meals or drowning in leftovers. This Dump & Bake Meatball Casserole is a cozy, small‑batch pasta bake that comes together with just a handful of ingredients and almost no effort. Everything — dry pasta, marinara sauce, water, herbs, and tender Italian meatballs — is stirred together and baked until the pasta absorbs the flavourful sauce and the cheese melts into a golden, bubbly topping. 

It’s budget‑friendly, freezer‑friendly, and perfect for anyone who wants a comforting, homemade dinner without the fuss. Whether you’re cooking for yourself or a small household, this easy casserole proves that simple ingredients can still deliver big, delicious results.

 

 I will be the first one to put my hand up and admit that I can be a bit lazy at times when it comes to cooking. I am always looking for shortcuts and easier ways to do things.  And if I can just use dump and bake recipes, so much the better!

I adore pasta.  It wasn't something I got to indulge in very much in my previous relationship, but now I am on my own, I can eat pasta to my heart's content. I have only myself to please now! If I want to have pasta 7 nights a week I can! (Not that I would!) 

Cooking for just one, or two people for that matter can be somewhat of a challenge to be sure.  Especially if you have been used to cooking for much larger groups through the years and are now facing an empty nest.

I've been living in an empty nest for 26 years now and on my own for six so I have gotten quite good at chopping recipes down to size for just myself.

Today's recipe suits me on all levels. Everything cooks in the one baking dish, even the pasta, which means that the pasta absorbs all of the flavors of the sauce.  Meatballs cook on top and at the end cheese is scattered over to make a moreish cheesy crust. The original recipe served six people, but I have cut it down to serve only three.  

This still means that I have extras but I just freeze the leftovers in single size containers ready to take out when I want some quick, easy and delicious for supper.

Rich tasty pasta, saucy and delicious with tender golden meatballs and plenty of cheese baked on top. What more could you ask for?  

I enjoyed with a salad on the side.

 

INGREDIENTS NEEDED

TO MAKE

DUMP & BAKE MEATBALL CASSEROLE

There is nothing overly complicated about this tasty casserole.

• 6 ounces (1 3/4 cups/169g) uncooked pasta (I used radiatore)
• 12 ounces (1 1/2 cups/340g) jarred marinara sauce (you can freeze what doesn't get used)
• 12 ounces (1 1/2 cups/354ml) water or beef stock
• 1/2 tsp Italian seasoning (See notes on how to make your own)
• 1/4 tsp garlic powder (not salt)
• 1/4 tsp onion powder (not salt)
• 12 frozen meatballs
• 3/4 cup (212g) grated Mozzarella cheese
• 2 TBS (22g) grated Parmesan cheese

 

NOTES ON INGREDIENTS

It is best to use short shaped pasta with ridges and indentations that will hug the sauce and cook in the allotted amount of time.

Use a good quality marinara. I used Rao's. Taste matters in a dish with so few ingredients. You can freeze any that you don't use for another time.

Make sure you use powders and not salts.

I make my own Italian seasoning, and tell you how to do the same in the recipe notes.

You can use frozen ready-made meatballs or your own homemade frozen meatballs. Mine were already cooked so you are basically just thawing them out and browning them on top of the casserole.

Grate your own cheese if possible.

 

HOW TO MAKE DUMP & BAKE MEATBALL CASSEROLE

This is a very simple make. 

1. Preheat the oven to 425*F/220*C/ gas mark 7. (non fan oven) Butter a baking dish about 5 by 13 inches in size. (Or a glass loaf pan.)
2. Measure the pasta into a bowl and combine with the marinara sauce, water/stock, garlic powder, onion powder and Italian seasoning. Mix well together. (I just stirred everything together well with a spoon.)
3. Pour this mixture into the baking dish, making sure that all of the pasta is submerged. Arrange the meatballs over top and cover tightly with aluminum foil. (Space the meatballs out evenly so it is easier to divide the casserole into portions later.)
4. Bake in the preheated oven for 35 to 40 minutes, or until the pasta is tender. (If it is still a bit hard, recover and bake for a bit longer.)
5. Uncover. Sprinkle both cheeses evenly over top. (Mix both cheeses together first.)
6. Bake, uncovered, for an additional 10 to 15 minutes, until golden, bubbly and the cheese has melted.
7. Leave to stand for 10 minutes before serving.

A salad and some garlic bread go very well on the side of this tasty casserole!

 

🌟HINTS AND TIPS FOR SUCCESS🌟

Use a “good” marinara sauce — it makes all the difference.

Because the pasta cooks in the sauce, its flavour becomes the backbone of the whole dish. A well‑seasoned, good‑quality marinara ensures the casserole tastes rich and satisfying.

Don’t worry about cooking the pasta first — the oven does the work.

Dry pasta goes straight into the casserole and absorbs the sauce as it bakes, giving it incredible flavour and perfect texture.

Water matters — measure it accurately.

The added water thins the sauce just enough for the pasta to cook properly and absorb moisture without drying out. Using broth will add an additional flavor boost.

Cover tightly for the first bake.

A snug foil cover traps steam, helping the pasta soften evenly and preventing the top from drying out.

Check the pasta before adding cheese.

If it’s not quite al dente after the first bake, simply recover and return it to the oven for a few more minutes — no stress.

Finish with a generous cheese topping.

A generous amount of mozzarella and parmesan melts into a golden, bubbly crust that makes the dish irresistible.

Let it rest before serving.

A short five‑minute rest helps the sauce settle and cling to the pasta, making serving easier and the texture perfect.

Keep small‑batch ingredients in the freezer.

Loose‑frozen meatballs and divided marinara portions make this recipe even quicker to pull together on busy nights.

 

FREQUENTLY ASKED QUESTIONS

DO I NEED TO COOK THE PASTA FIRST?

No — the dry pasta cooks right in the sauce as it bakes, absorbing all that flavour as it softens. You simply stir everything together, top with the meatballs, and pop it in the oven.

WHAT SHAPE OF PASTA SHOULD I USE?

Fusilli works beautifully because its spirals hold onto the sauce, but any short pasta (penne, rotini, farfalle) will cook the same way as long as you keep the liquid ratio the same. I used raddiatore today.

DO THE MEATBALLSNEED TO BE THAWED?

Not at all. Simply place the frozen meatballs on top of the pasta and proceed as per the recipe.

CAN I USE HOMEMADE MEATBALLS INSTEAD OF FROZEN MEATBALLS?

Absolutely. I usually make a big batch of meatballs and freeze them, ready to use in recipes like this one.

WHY SPECIFY A GOOD MARINARA SAUCE?

Because the sauce is one of the main flavour components — and the pasta cooks in it. A well‑flavoured sauce makes a noticeable difference in the final dish.

WHAT SIZE CASSEROLE DISH SHOULD I USE?

 A small 2‑cup casserole dish is perfect for this scaled‑down recipe. I used a Pyrex loaf pan.

WHAT IF MY PASTA ISN'T COOKED AFTER 35 MINUTES?

Simply cover it again with the foil, return to the oven and cook for a few minutes longer.

CAN I MAKE THIS AHEAD OF TIME?

You can assemble it ahead, but because the pasta absorbs liquid as it sits, it’s best baked immediately. If you do prep early, add a splash more water before baking.

CAN I DOUBLE THIS RECIPE?

Yes — the recipe is adapted from a full‑sized version and scales easily. Just use a larger casserole dish and increase the baking time slightly.

 

A FEW OTHER SMALL BATCH PASTA RECIPES TO ENJOY

Here are a few more delicious small batch pasta recipes you might also enjoy. These can always be doubled to serve more people.

SMALL BATCH CLASSIC LASAGNA - A small‑batch lasagna built for two, this cozy classic layers tender noodles with a rich, velvety meat sauce made from ground beef, Italian sausage, tomatoes, and a splash of cream for depth and silkiness . Instead of a traditional béchamel, it features a garlicky cottage cheese, Parmesan, and basil custard that bakes into a beautifully creamy, flavour-packed layer. Finished with bubbling mozzarella and Parmesan, it’s simple, comforting, and perfectly portioned — a hearty, satisfying lasagna without the leftovers.

SMALL BATCH INA GARTENS VODKA SAUCE & PASTA - A cozy, small‑batch spin on Ina Garten’s beloved vodka sauce, this dish turns simple pantry staples into something truly special. Sweet Spanish onion, fat cloves of garlic, good tomatoes, and a splash of vodka slow‑roast in the oven until they melt into a rich, velvety sauce that tastes far more luxurious than the short ingredient list suggests. A swirl of cream and a shower of Parmesan bring everything together, coating tender penne in a silky, restaurant‑worthy finish. It’s comforting, elegant, and wonderfully doable — the kind of pasta that makes you fall in love with cooking all over again.
