Easy lasagna stuffed shells. Stuffing the big shell pasta with the spinach lasagna filling is so easy because you can fill them up while the pasta shells are still firm -- not slippery.

Stuffed shells lasagna. Lasagna with pasta shells is a fun twist on typical lasagna! This lasagna stuffed shells recipe has all the flavors of lasagna -- with pasta shells instead of sheets of pasta.

So cozy and comforting. Baked pasta is a favorite comfort food for good reason: it’s warm and hearty and flavorful and, let’s face it, just makes us happy. So go ahead and curl up with a bowl of these lasagna stuffed shells whether it's the dead of winter or a random Tuesday.

Rotisserie chicken. No need to brown ground beef for this baked pasta dish. White meat rotisserie chicken -- or any leftover chicken or turkey -- makes it fast and easy to put these lasagna stuffed shells together, while keeping it lean and full of protein and flavor. 

On the healthier side. Typical Italian stuffed shells with meat and ricotta cheese can get a little heavy. These lasagna stuffed shells with cottage cheese are on the lighter side of things since I swapped out the ricotta, then added white rotisserie chicken instead of ground beef, tons of spinach, and marinara sauce that isn’t loaded in fat or sugar.

Ingredients and Substitutions

The ingredients for stuffed shells are all pretty simple -- and the secret magic ingredient isn't even shown below (it's just water!).

Jumbo pasta shells. You don’t need to search for oven ready pasta, you can just use regular jumbo shells to make these no-boil lasagna stuffed shells. 

Marinara sauce. Pasta sauces can be loaded with fat and sugar. So I always read the labels. It’s amazing what you’ll find. The spaghetti sauce I like the best, so far, is the Kirkland marinara from Costco. It’s also affordable. 

Cottage cheese. If you like your lasagna without ricotta, you’ll love this lasagna stuffed shells recipe with cottage cheese in the filling— it's a lighter option than ricotta and you might not notice the difference.

Egg. Adding a beaten egg to this lasagna filling helps bind it together so it stays in the shells — and doesn’t spill out all over the pan. 

Mozzarella cheese. I chose Mozzarella for its meltiness and because it’s a classic ingredient in lasagna. If you love something else that’s just as melty and gooey — go ahead and swap it out!

Parmesan cheese. Maybe you know that Parmesan cheese isn’t always what we think it is. Especially that grated stuff in the green tubes. Freshly grated Parmesan from a block is always best. But pre-shredded comes in handy, too. Just check the ingredients. You should only find milk, rennet, and salt on the list. 

Frozen spinach. I used frozen precooked spinach because fresh spinach contains a lot of water, which will get released as it cooks. Before adding the spinach, thaw it and wrap it in paper towels, then squeeze out allllll the water. All of it. Otherwise your spinach filling could get runny. 

Garlic powder. You can use fresh minced garlic, if you like. 

Italian seasoning. If you don’t have a jar of Italian seasoning in your spice cabinet, you can use the individual herbs: basil, oregano, rosemary, thyme, and marjoram. 

Rotisserie chicken. Shredded rotisserie chicken gets these lasagna stuffed pasta shells in the oven in a hurry. You can use freshly poached chicken or any leftover cooked chicken or turkey. 

Water. This is really the secret, magical, most important ingredient. Because it’s what turns regular old jumbo shells into no-boil pasta. A cup and a half of water added to the baking dish provides just enough extra moisture to cook the shells. Mind. Blown.

Recipe Essentials

Lasagna Pan

Okay, full disclosure, this is not the set I have, but this one is definitely on my wish list! Staub may be known for their cast iron cookware, but their ceramics are right up there in my book. And even though they come in a ton of fun colors, I can't stop looking at this matte black one!

Wooden Salad Bowl

What I love about a beautiful wooden salad bowl is that when it isn’t hanging onto your greens, it can hang out on your countertop filled with fruit, or stand alone as sculptural art on a shelf.

How to Make Lasagna Stuffed Shells

Preheat the oven to 375. Spray a 9 x 13 baking dish with cooking spray. 

Place 1 cup of marinara sauce in the bottom of the prepared baking dish. 

In a bowl, mix the cottage cheese, beaten egg, garlic powder, and Italian seasoning. Add the spinach, 1 cup of mozzarella cheese, and ½ cup of Parmesan cheese. 

With a spoon, stuff the shells with the spinach cottage cheese mixture. 

Layer the shredded rotisserie chicken over the stuffed lasagna shells. 

Cover the chicken with the remaining marinara sauce. 

Pour 1 ½ cups of water into the pan. 

Cover the marinara sauce with 1 cup of mozzarella cheese and ½ cup Parmesan cheese. 

Cover the pan in foil and bake for 60 minutes. Uncover and bake for another 10 minutes. 

Serve with ribbons of fresh basil and drizzles of pesto. 

Tips for making this stuffed jumbo shells recipe

Wrap the thawed spinach in paper towels and squeeze, squeeze, squeeze all the excess moisture out.

If you’re aiming to make a lightened up dish, keep an eye on the fat and sugar content in the marinara sauce. 

Baking the lasagna stuffed shells covered will keep all the moisture in so the shells will cook to the perfect al dente — without boiling them in a giant pot of water. 

Dried herbs are best in long-cooking recipes, like these lasagna baked shells, while fresh, soft herbs are perfect for adding right at the end. 

Adding a swirl of pesto right before you serve your baked pasta adds even more flavor and color.

How to Reheat Lasagna Stuffed Shells

What a gift to have lasagna stuffed shells leftovers for lunches or a don't-have-to-think-about-it dinner. You can reheat them in the oven or microwave, but know that while the stuffed shells were hanging out in the refrigerator, they may have absorbed quite a bit of moisture. So whatever method you choose, you will probably need to add some more pasta sauce or some water first.

OVEN: You can reheat your stuffed shells by covering them in foil and placing them in the oven. Heat at 350 for about 20-30 minutes, or until the internal temperature reaches 165.

MICROWAVE: You can also nuke your stuffed shells. Just cover them tightly and reheat in one-minute increments until everything is warm.
