Step-by-Step Instructions
Preparation steps
First, preheat your oven to 375°F (190°C). This step gets the oven ready for baking. Next, cook the large pasta shells. Follow the package instructions until they are al dente. This means they should be firm but not hard. Once cooked, drain the shells and set them aside.
Now, grab a mixing bowl. Combine the ricotta cheese, shredded mozzarella, and grated Parmesan. Add the chopped spinach and basil pesto to the bowl. Sprinkle in garlic powder, salt, and pepper. Mix all the ingredients well until they blend together nicely.
Cooking process
While preparing, keep an eye on the shells. Make sure they do not stick together. If they do, gently separate them with a fork. Once your cheese mixture is ready, it’s time to stuff the shells. Use a spoon to fill each shell with the cheese mix. Use a good amount, but don’t overfill.
Assembly and baking tips
Place the stuffed shells seam side up in a baking dish. After all the shells are in, spread marinara sauce over them. Make sure to cover each shell completely with sauce. This keeps them moist while baking.
For extra cheesiness, sprinkle any leftover mozzarella and Parmesan on top. Cover the dish with aluminum foil. Bake for 20 minutes. After that, remove the foil and bake for another 10 minutes. This helps the cheese get bubbly and golden.
Once they are done, let the shells cool for a few minutes. Finally, garnish with fresh basil leaves before serving. Enjoy your delicious Cheesy Spinach Pesto Stuffed Shells!
Tips & Tricks
How to prevent shells from breaking
To keep your pasta shells intact, cook them carefully. Start with a large pot of water. Add salt to enhance the flavor. Boil the shells until they are al dente. This means they should still be firm when you bite them. After cooking, drain them gently. Rinse with cold water to stop the cooking process. Handle the shells with care to avoid cracking.
Best practices for stuffing pasta
When stuffing the shells, use a small spoon or a piping bag. This makes it easier to fill them evenly. Don’t overfill; leave a little space at the top. If you overstuff, the filling may spill out during baking. Place the stuffed shells seam side up in your baking dish. This helps keep them together and makes for a nice presentation.
Enhancing flavors with spices
Add extra flavor by using spices. You can mix in a pinch of red pepper flakes for heat. Fresh herbs like parsley or thyme can also brighten the dish. Consider adding a dash of lemon juice for a fresh twist. These small changes can elevate your Cheesy Spinach Pesto Stuffed Shells from tasty to amazing. Always taste your filling before stuffing to adjust the flavors as needed.
Pro Tips
- Use Fresh Spinach: Always opt for fresh spinach over frozen for a brighter flavor and better texture in your stuffed shells.
- Customize Your Cheese: Feel free to mix in other cheeses like feta or goat cheese for a unique twist on flavor.
- Make Ahead: Prepare the stuffed shells in advance and refrigerate them until ready to bake, making dinner prep a breeze.
- Extra Flavor Boost: Add red pepper flakes or Italian seasoning to the marinara sauce for an extra kick of flavor.

Variations
Vegetarian options
You can keep these stuffed shells vegetarian by using plant-based cheese. Look for ricotta made from nuts or tofu. You can also add more veggies. Artichokes, mushrooms, or bell peppers work well. They add flavor and nutrients.
Protein additions (chicken, sausage)
For a protein boost, add cooked chicken or sausage. Shred the chicken and mix it into the cheese filling. If you prefer sausage, choose Italian sausage for extra flavor. Cook it first, then crumble it into the mixture. This adds a savory touch to your meal.
Gluten-free alternatives
If you need a gluten-free option, use gluten-free pasta shells. Many brands offer great choices that hold up well. You can also make your own shells using almond flour. Just ensure your other ingredients are also gluten-free. This way, everyone can enjoy this tasty dish.

After enjoying Cheesy Spinach Pesto Stuffed Shells, you may have some leftovers. To store them, let the shells cool completely. Then, place them in an airtight container. This keeps the flavors fresh and prevents drying out. Store the container in the fridge for up to three days.
Reheating instructions

Bake for about 15-20 minutes. Check to ensure they are heated through. If using a microwave, heat one serving at a time for about 2-3 minutes.
Freezing guidelines
