Ingredients Required for Pesto Stuffed Shells

When it comes to the ingredients for Pesto Stuffed Shells, each component plays a crucial role in achieving the perfect balance of flavors.

The combination of cottage cheese and mozzarella gives a delightful texture, while the parmesan adds a nutty flavor. And, of course, the pesto ties everything together beautifully, offering a burst of fresh basil flavor. Let’s dive into these ingredients!
- 21 jumbo shells

- 1 large egg
How to Assemble Pesto Stuffed Shells

Assembling Pesto Stuffed Shells is such a rewarding experience. With a few simple steps, you’ll create a dish that’s not only delicious but visually stunning. Let’s walk through each step together, ensuring your shells are perfectly stuffed and ready for baking.
- Preheat your oven to 375ºF. This is a crucial step as you want your oven to be hot when the shells go in, ensuring an even bake and melty cheese on top.
- Lightly spray a 9×13-inch baking dish with cooking spray. This will prevent the shells from sticking to the dish, making cleanup easier and ensuring that every bite is perfect.
- Cook the jumbo pasta shells according to the package directions. Once cooked, drain them well, ensuring no water remains inside the shells. This will help the filling adhere better.
- Pour about 1/2 cup of spaghetti sauce into the prepared pan, spreading it evenly across the bottom. This layer will keep the shells moist as they bake.
- In a mixing bowl, combine the cottage cheese, 1½ cups of mozzarella cheese, grated parmesan cheese, egg, and pesto. Stir until well combined. You’ll want a creamy mixture that is easy to stuff into the shells.
- Carefully stuff each cooked shell with the cheese mixture. It’s okay if some filling spills out; it adds to the homey look of the dish. Place the stuffed shells open side up on top of the sauce in the baking dish.
- Once all the shells are stuffed, spread the remaining spaghetti sauce over the tops of the shells. This will keep them moist and flavorful.
- Sprinkle the remaining ½ cup of mozzarella cheese over the top. A generous layer of cheese is essential for that golden, bubbly finish!
- Bake uncovered for about 30 to 35 minutes. You’ll know they’re done when the cheese is melted and bubbly, and the sauce is hot. Let the dish cool for a few minutes before serving to help set the filling.
Things Worth Knowing
- Cook the shells al dente: This ensures they hold their shape when stuffed and baked.
- Let the filling cool: Allow the cheese mixture to cool slightly before stuffing; this makes it easier to handle.
- Bake covered: If you want extra moisture, cover the dish with foil for the first 15 minutes of baking.
- Use fresh pesto: If possible, use fresh pesto for a burst of flavor. You can also make your own at home!
Making Adjustments

Adjusting recipes can be fun and rewarding! Here are some tips for making Pesto Stuffed Shells your own:
- Storage: Store leftovers in an airtight container in the fridge for up to 3 days. Reheat in the oven for the best texture.
- Freezing: You can freeze the assembled dish! Just cover it tightly with plastic wrap and aluminum foil. It’ll keep for 3 to 4 months. Thaw completely before baking.
- Pairing: Serve with a crisp green salad and garlic bread for a complete meal.
- Vegetarian option: This is a meatless dish, but feel free to add vegetables like spinach or mushrooms to the filling.
- Herbs: Experiment with other herbs in the filling, such as thyme or oregano, for an extra flavor boost.
