Ingredients
List of Ingredients
To make Pesto Spinach Stuffed Shells, you will need:
– 20 jumbo pasta shells
– 2 cups fresh spinach, roughly chopped
– 1 cup creamy ricotta cheese
– 1 cup shredded mozzarella cheese
– 1/2 cup freshly grated Parmesan cheese
– 1/2 cup prepared basil pesto
– 1 garlic clove, finely minced
– 1 teaspoon extra virgin olive oil
– Sea salt and freshly cracked black pepper to taste
– 1 cup marinara sauce (for topping)
– Fresh basil leaves for garnish
Freshness Tips for Ingredients
Fresh ingredients make a big difference. Use fresh spinach for the best taste. Look for vibrant green leaves. When you buy basil pesto, check the date on the jar. If you can, make your own pesto for a burst of flavor. Store cheeses in the fridge until you’re ready to use them. Keep garlic in a cool, dark place for longer freshness. The same goes for your pasta; store it in a dry, cool spot.
Substitutions for Dietary Restrictions
You can easily adjust this recipe for different diets. For a dairy-free option, use tofu or a nut-based cheese. Substitute the ricotta with cashew cream or almond cheese. If you’re gluten-free, swap the jumbo pasta shells for gluten-free pasta. You can also add other veggies like mushrooms or zucchini if you want more nutrients. Always check for allergens in store-bought items, like pesto or marinara sauce, to ensure they fit your needs.

Step-by-Step Instructions
Prepping the Pasta Shells
Start by preheating your oven to 375°F (190°C). This helps the shells bake evenly. Next, bring a large pot of salted water to a boil. Cook the jumbo pasta shells according to the package instructions until they are al dente. This usually takes about 10 minutes. Once they are done, drain the shells in a colander and let them cool slightly. You want them cool enough to handle but warm enough to fill easily.
Making the Spinach and Cheese Filling
While the shells cool, heat a skillet over medium heat and add the olive oil. Once hot, add the minced garlic and sauté for about 1 minute until it smells nice. Then, add the chopped spinach. Cook this down for 2-3 minutes until it wilts. After that, remove the skillet from the heat and let it cool for a few minutes. In a large bowl, mix the creamy ricotta, half of the mozzarella, the Parmesan, and the basil pesto. Add the cooked spinach and season with salt and pepper. Stir until everything blends well.
Assembling and Baking the Stuffed Shells
Now it’s time to fill the shells. Take each shell and spoon the spinach and cheese mixture inside. Make sure each shell is full but not overflowing. Place the filled shells in a baking dish with the open side facing up. Drizzle the marinara sauce over the stuffed shells, covering them well. Sprinkle the remaining mozzarella on top. Cover the dish with aluminum foil and place it in the oven. Bake for 20 minutes, then remove the foil and bake for another 10 minutes until the cheese is bubbly and golden. After baking, let the dish cool for a few minutes. Before serving, add fresh basil leaves on top for a nice touch.
Tips & Tricks
How to Ensure Perfectly Cooked Shells
To get the best pasta shells, cook them just right. Boil the shells in salted water. Al dente means firm but cooked. Follow the package time for cooking. After cooking, drain them and cool slightly. This helps prevent sticking and makes stuffing easier.
Enhancing Flavor with Additional Ingredients
You can add extra flavor to your stuffed shells. Try adding sun-dried tomatoes for a sweet touch. You can also mix in olives for a salty kick. For a spice boost, consider red pepper flakes. Fresh herbs like thyme or oregano bring freshness. You could even swap half of the ricotta with goat cheese for a tangy flavor.
Common Mistakes to Avoid
Avoid overcooking the pasta shells. They should be firm enough to hold the filling. Don’t skip the cooling step after cooking. Stuffing hot shells can be messy. When layering marinara sauce, make sure every shell gets some. This adds moisture and flavor during baking. Finally, cover the dish while baking to keep the shells soft and the cheese from burning.
Pro Tips
- Tip 1: Use fresh spinach for a vibrant flavor and optimal nutrition.
- Tip 2: For an extra creamy filling, consider mixing in some cream cheese with the ricotta.
- Tip 3: To save time, prepare the filling in advance and refrigerate it until you’re ready to stuff the shells.
- Tip 4: Experiment with different cheeses like goat cheese or feta for a unique twist on the traditional flavor.
Variations
Vegetarian Variations
You can easily make this dish vegetarian. The original recipe already meets this need. The combination of spinach, ricotta, and pesto creates a rich flavor. If you want to add more veggies, consider mixing in roasted bell peppers or mushrooms. They will add more texture and taste. You can also use kale instead of spinach for a different twist.
Vegan and Dairy-Free Options
To make this meal vegan, swap out the cheese and use a plant-based ricotta. You can find many brands that taste great. For the mozzarella, try a vegan cheese made from nuts or soy. Use a vegan pesto as well. You can make your own by blending basil, nuts, and nutritional yeast. This keeps the flavor while fitting a vegan diet.
Protein Additions (Chicken, Tofu, etc.)
Want to add protein? Cooked chicken breast works well. Shred it and mix it into the cheese filling. Tofu is another great option. Press and cube the tofu, then sauté it until golden. Mix it into the filling for extra protein. You can also use cooked ground turkey or beef if you prefer. These additions will make the dish heartier and more satisfying.
