Pesto Stuffed Shells

Who doesn’t love cute little pasta bundles?? These Pesto Stuffed Shells remind me of little baby lasagnas that have yet to grow into their full form. They have all the same goodies as a spinach lasagna, but rolled into easy-to-portion pasta shells. And to make life easier, I worked some store-bought pesto into the filling to take care of all the seasoning needs in one swoop, instead of adding herbs and spices one by one. So fast, so easy. And these little guys freeze beautifully, so don’t be afraid of the large batch size. simply let them cool completely, transfer to a freezer safe container, and stash ’em in your freezer for later!

This recipe made about 22 stuffed shells for me, but your distance may vary. I suggest boiling about 25 shells just in case you have extra filling or a couple of them rip during the stuffing process. I used about 2/3 of a 12oz. box of jumbo shells, which gave me 22 individual shells.

Pesto Stuffed Shells

Pesto Stuffed Shells are an easy and impressive dish that is a filling and flavorful alternative to a meat-heavy Italian meal. 

Total Cost $7.81 recipe / $1.56 serving
Prep Time 15 minutes
Cook Time 45 minutes
Total Time 55 minutes
Servings 5 4 shells each

Ingredients

  • 1/2 lb. frozen spinach, thawed $0.85
  • 15 oz. ricotta $1.99
  • 1 cup shredded mozzarella $1.00
  • 1/2 cup basil pesto $0.85
  • 1 large egg $0.27
  • 8 oz. jumbo pasta shells (about 22-25 shells) $1.66
  • 24 oz. pasta sauce $1.19

Instructions

  1. Make sure the spinach is completely thawed, then squeeze out as much of the moisture as possible. Add the spinach to a large bowl with the ricotta, mozzarella, pesto, and egg. Stir until the ingredients are well combined, then refrigerate until it's ready to be used.

  2. Bring a large pot of water to a boil, then add the jumbo shells. Cook the shells just until they're tender, making sure not to over cook the pasta. The longer the shells boil, the more likely they are to tear during the stuffing process. Drain the shells in a colander and then rinse briefly with cool water to make them cool enough to handle.

  3. Preheat the oven to 350ºF. Spread about 1 cup of pasta sauce in the bottom of a large casserole dish.

  4. One by one, stuff each shell with a couple tablespoons of the cheese, pesto, and spinach mixture. Place the shells in the casserole dish as you stuff them.

  5. Once the shells are all stuffed, pour the remaining two cups of pasta sauce over top. Bake the shells for about 30 minutes in the preheated oven, or until the sauce is bubbling up around the edges. Serve hot.

Pesto Stuffed Shells Filling Ingredients

First prepare the filling for the shells. Make sure your 1/2 lb. frozen spinach is completely thawed, then squeeze out as much of the moisture as possible. Combine the spinach in a bowl with 15oz. ricotta, 1 cup shredded mozzarella, 1 large egg, and 1/2 cup pesto.

Mix those ingredients together until they’re well combined, then refrigerate them until they’re ready to be used.

Cooked Jumbo Shells

Bring a large pot of water to a boil, then add about 22-25 jumbo pasta shells (about 8oz.). Boil the shells just until they’re tender, but still sturdy. Over cooking the pasta shells makes them difficult to stuff without ripping. Drain the pasta in a colander and rinse briefly with cool water to make them easy to handle.

Pasta Sauce in Casserole Dish

Preheat the oven to 350ºF. Spread about 1 cup pasta sauce in the bottom of a large casserole dish (about 9×13″). 

Stuff Jumbo Shells

Stuff each pasta shell with about 2 Tbsp of the prepared spinach and pesto cheese filling, then place them in the casserole dish.

Line the shells up with one another so they are fairly closely packed.

Pour Pasta Sauce Over Pesto Stuffed Shells

Finally, pour the remaining 2 cups of pasta sauce over the shells.

Pesto Stuffed Shells Ready to Bake

Since the shells are stuffed with cheese, I didn’t feel the need to top them with even more cheese… but that’s just me. ;P

Pesto Stuffed Shells Baked

Bake the Pesto Stuffed Shells in the preheated oven for about 30 minutes, or until the sauce is a little bubbly and browned around the edges.
