The Essential Ingredients for This Shortcut Casserole
This iconic dish uses a handful of smart, convenient ingredients to create its signature comforting and cheesy flavor.
- The Shortcut Stars:
- Frozen Italian Meatballs: Using a package of your favorite brand of frozen, fully cooked, 1/2-ounce Italian meatballs is the key to making this a super-fast and easy meal. There’s no need to spend time making a complicated ricotta and meat filling from scratch!
- Jarred Spaghetti Sauce: A high-quality, store-bought spaghetti sauce is a fantastic shortcut that provides a deep, slow-simmered flavor with zero extra effort. A classic marinara or a garden-style vegetable sauce are both excellent choices.
- The Pasta & Cheese:
- Jumbo Pasta Shells: These large, shell-shaped pasta noodles are the perfect, classic vessel for stuffing with delicious fillings.
- Part-Skim Mozzarella Cheese: A bag of pre-shredded, low-moisture, part-skim mozzarella is the secret to that beautiful, stringy, and classic “cheese pull” and a perfectly golden-brown, not greasy, topping.
Step-by-Step to the Easiest Stuffed Shells
This delicious, one-dish meal is incredibly simple to prepare.
Step 1: Cook the Pasta Shells
First, preheat your oven to 350°F (175°C). Generously grease a 13×9-inch baking dish.
Bring a large pot of heavily salted water to a boil. Cook your 36 uncooked jumbo pasta shells according to the package directions until they are al dente.
Drain the cooked shells and immediately rinse them under cold water.
Pro Tip: Rinsing the shells in cold water is a crucial step! It stops the cooking process to prevent them from becoming mushy, and it also makes them cool enough for you to handle comfortably while you are stuffing them.
Part 2: Assemble Your Easy Stuffed Shells
Step 1: Spread about 1/2 cup of your spaghetti sauce evenly into the bottom of your prepared 13×9-inch baking dish.
Pro Tip: This is a key step that prevents the pasta shells from sticking to the bottom of the pan and burning while they bake.
Step 2: Now for the fun and easy part! Fill each of your cooked pasta shells with one thawed, frozen Italian meatball.
Step 3: Arrange the stuffed shells, with the opening facing up, in a single layer in the baking dish over the sauce.
Step 4: Top the shells with all the remaining spaghetti sauce.
Step 5: Sprinkle the 2 cups of shredded mozzarella cheese evenly over the top of the entire casserole.
Part 3: Bake to Bubbly, Cheesy Perfection
Step 1: Cover the baking dish with aluminum foil. Bake for 35 minutes.
Pro Tip: Baking the casserole covered at first is a crucial step! It traps the steam inside the dish, which helps to heat the filling and the sauce all the way through without the cheese on top becoming too brown or burnt.
Step 2: After 35 minutes, carefully remove the foil. Return the casserole to the oven and continue to bake, uncovered, for another 3 to 5 more minutes, until the casserole is hot and bubbly and the cheese on top is completely melted and a beautiful light golden brown.
Let the casserole cool for a few minutes before serving.

Notes

Storage and Make-Ahead Tips
This Meatball Stuffed Shells casserole is the perfect make-ahead meal for a busy week or a potluck.
- Make-Ahead: You can fully assemble the entire, unbaked casserole up to 24 hours in advance. Simply cover it tightly with foil and store it in the refrigerator. When you are ready to bake, you may need to add 10-15 minutes to the total baking time since it will be starting from cold.
- Storage: Store any leftovers, well-covered, in the refrigerator for up to 4 days.
- Freezing: This casserole freezes beautifully! You can freeze it either before or after baking. Let it cool completely, then wrap the pan very well in a double layer of plastic wrap and then a layer of foil. It will keep in the freezer for up to 3 months. Thaw it overnight in the refrigerator before baking or reheating.

Creative Recipe Variations
- Make it a Classic Ricotta Stuffed Shell: For a more traditional, vegetarian version, you can skip the meatballs and instead fill the shells with a classic ricotta filling. Simply mix together 1 carton (15 ounces) of ricotta cheese, 1 cup of shredded mozzarella cheese, 1/2 cup of grated Parmesan cheese, 1 large egg, and some fresh parsley.
- Use a Different Sauce: If you’re not in the mood for a red sauce, this recipe is also absolutely fantastic with a rich and creamy Alfredo sauce or a vibrant basil pesto.
- Add Some “Hidden” Veggies: For an extra boost of nutrition, you can stir about 1 cup of cooked, well-squeezed, and finely chopped spinach into your spaghetti sauce before you assemble the casserole.

Frequently Asked Questions (FAQs)
Q1: What is the absolute best way to stuff the pasta shells without them breaking or tearing?
The key is to cook your shells until they are just al dente (tender but still have a firm bite) and to rinse them under cold water so they are easy to handle. Then, simply hold a shell in one hand, gently open it, and use your other hand to place the meatball inside. The shells are surprisingly sturdy!
Q2: Can I make this casserole ahead of time for a potluck?
Yes, this is a perfect make-ahead meal! You can fully assemble the entire unbaked casserole, cover it tightly, and keep it in the refrigerator for up to 24 hours. When you are ready to bake, just remove the cover and pop it in the oven (you may need to add 10-15 minutes to the baking time, as it will be starting from cold).
Q3: Do I have to thaw the frozen meatballs before I stuff them in the shells?
Yes, it is highly recommended to thaw the meatballs first, as the recipe suggests. This will ensure that the meatballs get heated all the way through to the center in the relatively short baking time. You can easily thaw them in the microwave.
Q4: Can I freeze this casserole?
Yes, this is a fantastic freezer meal! You can freeze it either baked or unbaked. Let the casserole cool completely, then wrap the dish very well in a double layer of plastic wrap and then a layer of foil. It will keep in the freezer for up to 3 months. Let it thaw overnight in the refrigerator and then bake (or reheat) it.
Q5: What else can I serve with these stuffed shells?
This is a fantastic, hearty, all-in-one meal. It is perfect when served with a simple side of crusty garlic bread (for sopping up all that extra sauce!) and a simple green salad or a Caesar salad with a bright vinaigrette.
