Ingredients with Quantities

• 20 jumbo pasta shells
• 1 tablespoon olive oil
• 2 cups fresh spinach, chopped
• 1 ½ cups mushrooms, finely chopped
• 2 cloves garlic, minced
• 1 cup ricotta cheese
• 1 cup shredded mozzarella cheese (plus extra for topping)
• ½ cup grated Parmesan cheese
• 1 egg
• 1 teaspoon Italian seasoning
• ½ teaspoon salt
• ¼ teaspoon black pepper
• 2 cups marinara sauce

Directions and Preparation Method

Step 1: Cook the Pasta Shells

Bring a large pot of salted water to a boil. Add the jumbo pasta shells and cook them according to package instructions until they are just al dente. Be careful not to overcook them, as they will continue to soften while baking. Once done, drain the shells and lay them out on a baking sheet or plate to prevent sticking.

Step 2: Sauté the Vegetables

Heat olive oil in a large skillet over medium heat. Add minced garlic and cook for about one minute until fragrant. Next, stir in the chopped mushrooms and spinach. Cook for 5–7 minutes, allowing the vegetables to soften and release their moisture. Continue cooking until all liquid evaporates. Remove from heat and let the mixture cool slightly.

Step 3: Make the Filling

In a large mixing bowl, combine ricotta cheese, shredded mozzarella, Parmesan, egg, Italian seasoning, salt, and black pepper. Mix until smooth and creamy. Once the vegetables have cooled slightly, fold them into the cheese mixture. This filling should be thick, rich, and flavorful.

Step 4: Prepare the Baking Dish

Preheat your oven to 375°F (190°C). Spread 1 cup of marinara sauce evenly on the bottom of a 9×13-inch baking dish.

Step 5: Assemble the Shells

Take each cooled shell and carefully fill it with 2–3 tablespoons of the prepared cheese and vegetable mixture. Place the filled shells snugly into the baking dish, open side up.

Step 6: Add Sauce and Cheese

Pour the remaining marinara sauce evenly over the stuffed shells. Sprinkle an extra layer of shredded mozzarella on top for a cheesy, golden crust once baked.

Step 7: Bake

Cover the dish with foil and bake in the preheated oven for 25 minutes. After that, remove the foil and bake for an additional 10 minutes, or until the cheese is bubbly and lightly golden.

Step 8: Serve

Remove from the oven and let cool for a few minutes. Garnish with fresh basil or parsley if desired. Serve hot with garlic bread or a fresh green salad.

FAQs

1. Can I make these stuffed shells ahead of time?

Yes! You can assemble the stuffed shells up to a day in advance. Simply cover the dish tightly with foil and refrigerate. When ready to bake, add 10 extra minutes to the covered baking time.

2. Can I freeze Mushroom & Spinach Stuffed Shells?

Absolutely. These shells freeze beautifully. Assemble the dish as directed but don’t bake. Cover tightly with plastic wrap and foil, then freeze for up to 2 months. When ready, bake from frozen at 375°F, adding an additional 20–25 minutes to the baking time.

3. Can I substitute the vegetables?

Yes. While mushrooms and spinach provide a wonderful flavor balance, you can swap them for zucchini, kale, broccoli, or even roasted red peppers. Just make sure to sauté and remove excess liquid before mixing into the filling.

4. What’s the best cheese to use?

Ricotta gives the creamy base, but you can also mix in cottage cheese for a lighter version or mascarpone for extra richness. Mozzarella provides the melt, and Parmesan adds a salty bite.

5. Can I make this recipe gluten-free?

Yes, simply use gluten-free jumbo pasta shells available in many stores. All other ingredients are naturally gluten-free.

6. How do I keep the shells from sticking together?

After boiling, drain the shells and immediately rinse them under cold water. Arrange them on a baking sheet in a single layer, drizzling a little olive oil to prevent sticking.

7. What side dishes go well with stuffed shells?

These shells pair wonderfully with garlic bread, a crisp Caesar salad, roasted vegetables, or even a light soup like minestrone or tomato basil.

8. Can I add protein to this dish?

Yes. If you prefer a heartier version, add cooked ground beef, turkey, sausage, or shredded chicken to the filling mixture.
