Lasagna Stuffed Shells pack all the components of a classic lasagna — seasoned ground beef, a ricotta-based cheese filling, marinara, and melted mozzarella — into jumbo pasta shells that bake in a single pan. The format makes portioning easy and every shell holds its own filling-to-pasta ratio, which matters when you’re feeding a table of people with different appetites. It’s a reliable, crowd-sized baked pasta that reheats well and doesn’t require any special technique.
Ingredient notes
- Jumbo pasta shells: Buy more than the recipe calls for. Shells crack during boiling more often than you’d expect, and you’ll want extras to fill the pan properly.
- Ricotta vs. cottage cheese: Either works. Cottage cheese gives a slightly lighter, less dense filling. If you use cottage cheese, drain it briefly through a fine mesh strainer first so the filling doesn’t turn watery in the oven.
- Marinara sauce: A plain, low-sugar jarred marinara is fine here — the meat and cheese carry the flavor. Avoid anything labeled “chunky” as large vegetable pieces make stuffing the shells awkward.
- Mozzarella: Pre-shredded works, but block mozzarella shredded by hand melts more evenly and doesn’t clump.
The short version of why this works
Two things make this dish work reliably. First, cooking the ground beef fully before it goes into the shells — not just browning it, but getting it to 160°F (71°C) and draining the fat — keeps the filling from making the shells greasy and soggy during baking. Second, spreading sauce on the bottom of the baking dish before you place the shells prevents the pasta from sticking and drying out on the underside. Shells sitting directly on a dry pan will toughen at the base while the tops are still cooking. The sauce underneath acts as a buffer and keeps the whole shell tender through the full bake time.
What can go wrong
- Shells tear when you try to fill them: This usually means they were slightly undercooked and stiff, or overcooked and fragile. Pull them out of the boiling water when they’re pliable but still hold their shape — they’ll finish cooking in the oven. Lay them in a single layer on a lightly oiled baking sheet while you work so they don’t stick together.
- Watery filling that pools in the pan: Excess moisture from ricotta or cottage cheese is the usual cause. Press the cheese briefly in a strainer or between paper towels before mixing. Also make sure the meat is well-drained after browning.
- Filling falls out during serving: The shells need to rest for 10 minutes out of the oven before you plate them. Cutting into them too early means the filling hasn’t set and it slides out. Skip the garnish — not worth the extra dish — and just let them rest covered with foil.
- Top layer of cheese burns before the shells are heated through: Cover the pan tightly with foil for the first two-thirds of the bake time, then uncover for the last 10–15 minutes to brown the cheese. If you put it in uncovered from the start, the mozzarella on top will overcook before the center shells are hot.
- Shells at the edges dry out: Make sure the sauce covers the bottom of the dish generously and spoon a little extra over the outer shells before covering with foil. The edges of a baking dish run hotter and the shells there lose moisture faster.
Make-ahead notes
You can assemble the entire pan up to 24 hours ahead, cover it tightly with foil, and refrigerate it unbaked. Pull it out 30 minutes before it goes into the oven so it’s not stone cold in the center — a cold pan straight from the fridge will need an extra 15–20 minutes of bake time and the edges will overcook before the middle catches up. For freezing, the assembled unbaked pan keeps well for up to 3 months wrapped in two layers of foil. Thaw it overnight in the refrigerator before baking. Already-baked leftovers reheat well in a 350°F (175°C) oven covered with foil for 20–25 minutes, or individual portions can go in the microwave with a splash of water added to the dish to prevent the pasta from drying out.
The Best Lasagna Stuffed Shells
Ingredients
- 28 pieces giant pasta shells
1 pound ground turkey (minced turkey) - or ground beef
4 cups Marinara sauce (tomatoes, garlic, herbs, and onions - pasta sauce in southern hemisphere for Italian seafood dish)
15 ounces Ricotta cheese
2 cups Mozzarella cheese - shredded
¼ cup Parmesan cheese - shredded
Instructions
- Preheat the oven to 350°F. Spray a 9×13 inch baking pan with cooking spray and set aside.
- Bring a large pot of water to a boil and cook shells until just al dente. Drain and rinse with cool water (Note: I always cook more shells than I think I’m going to need since a few inevitably break during the boiling process).
- While the shells are boiling, brown ground turkey in a large saucepan. Drain fat and transfer ground turkey to a bowl. Add marinara sauce and mix well.
- Stuff shells- first with half a spoonful (about half a tablespoon) of ricotta, then a spoonful (about a tablespoon) of meat sauce (as you can see, I wasn’t super exact about this part). Place shells in a prepared baking dish, with the opening up (Note: you should have some meat sauce leftover once all the shells are stuffed).
- Sprinkle half of the mozzarella cheese on top of the shells, followed by the remaining meat sauce. Sprinkle the other half of the mozzarella on top of the sauce, then the parmesan cheese.
- Bake for 20 minutes or until the sauce is hot and the cheese has melted.

Frequently asked questions
Can I use a different ground meat instead of beef?
Yes — ground pork, a beef-pork blend, or ground turkey all work in this recipe. If you use ground turkey or chicken, cook it to an internal temperature of 165°F (74°C) and expect a slightly leaner, less fatty filling, which some people prefer. A beef-pork mix adds a bit more richness and is worth trying if you have both on hand.
How many shells does this recipe make and will it feed a family of six?
A standard recipe using a 9×13 pan typically yields around 20–24 stuffed shells, which feeds 4–6 people generously depending on appetite and what you serve alongside. For a hungrier crowd or if this is the only main dish, add a second smaller baking dish with any remaining shells and sauce rather than trying to cram more into one pan.
Can I freeze this after it’s already been baked?
Yes, baked shells freeze fine for up to 2 months. Portion them into airtight containers once fully cooled, and add a spoonful of extra marinara on top before sealing to prevent the pasta from drying out during storage. Reheat from frozen in a covered oven-safe dish at 350°F (175°C) for 35–45 minutes, or thaw overnight in the fridge first to cut that time roughly in half.
My shells keep splitting when I boil them — what am I doing wrong?
The most common cause is boiling them too vigorously or for too long. Use a large pot with plenty of water, keep the boil at a moderate rather than rolling level, and stir gently once or twice during cooking. Pull them out a minute or two before the package’s al dente time — they should be flexible but not fully soft, since they’ll continue cooking in the oven.
