Ingredients
– 12 jumbo pasta shells
– 1 cup ricotta cheese
– 1 cup shredded mozzarella cheese
– 1/2 cup grated Parmesan cheese
– 2 cups fresh spinach, chopped
– 1 cup cremini mushrooms, diced
– 1 beaten egg
– 2 cloves garlic, minced
– 1 teaspoon onion powder
– 1 teaspoon Italian seasoning
– Salt and pepper to taste
– 1 cup marinara sauce
– Olive oil for sautéing
Instructions
1. Preheat your oven to 375°F (190°C). This ensures even cooking and optimal texture for the stuffed shells.
2. Cook the jumbo pasta shells in a large pot of salted boiling water until al dente, about 8-10 minutes. Drain and set aside to cool slightly.
3. In a skillet over medium heat, add olive oil and sauté the diced cremini mushrooms and minced garlic until the mushrooms are soft and caramelized, about 5-7 minutes. Add the chopped spinach and cook until wilted, about 2-3 minutes. Season with salt and pepper to taste.
4. In a large bowl, combine the ricotta cheese, half of the mozzarella cheese, grated Parmesan cheese, beaten egg, onion powder, Italian seasoning, and the sautéed mushroom and spinach mixture. Mix until well combined.
5. Spread a thin layer of marinara sauce on the bottom of a baking dish.
6. Carefully stuff each cooked jumbo shell with the cheese and vegetable mixture, and place them seam-side up in the baking dish.
7. Top the stuffed shells with the remaining marinara sauce and sprinkle the rest of the mozzarella cheese on top.
8. Cover the baking dish with aluminum foil and bake for 25 minutes. Remove the foil and bake for an additional 10-15 minutes, or until the cheese is bubbly and golden.
Understanding the Ingredients
Jumbo Pasta Shells
Jumbo pasta shells are the perfect vessel for this dish, providing a generous pocket to hold the rich filling. Their size and shape allow them to absorb flavors from sauces and other ingredients, ensuring every bite is delicious.
Spinach
Spinach is a powerhouse of nutrition, rich in vitamins A, C, and K, as well as minerals like iron and calcium. Its mild flavor enhances the overall taste of the dish while also contributing to its vibrant green color.
Mushrooms
Cremini mushrooms bring an earthy taste and meaty texture that complements the creamy filling. Their ability to absorb flavors during cooking ensures they blend seamlessly with the other ingredients.
Cheeses
The combination of ricotta, mozzarella, and Parmesan cheeses creates a creamy and flavorful filling. Ricotta adds a light and fluffy texture, while mozzarella contributes gooeyness, and Parmesan adds a sharp, nutty flavor that elevates the dish.
Egg and Seasonings
The beaten egg serves as a binding agent, helping to hold the filling together and ensuring it maintains its shape during baking. Seasonings like garlic, onion powder, and Italian seasoning enhance the flavor, making each bite memorable.
Preparation Steps
Prepping the Oven
Preheating the oven is crucial for achieving the best results. It ensures that the stuffed shells cook evenly and helps to develop that desirable golden cheese crust on top.
Cooking the Pasta
Cooking the jumbo shells al dente is essential. This means they should be firm to the bite, as they will continue to cook in the oven. Overcooked shells can become mushy and lose their structural integrity.
Sautéing the Vegetables
Sautéing the mushrooms and garlic not only enhances their flavors through caramelization but also brings out the natural sweetness of the ingredients. This step is vital for building a robust flavor profile in the dish.

Creating the Filling
To achieve the perfect filling for your Cheesy Spinach and Mushroom Stuffed Shells, start by thoroughly mixing the ingredients. Combine sautéed spinach, mushrooms, ricotta cheese, mozzarella, Parmesan cheese, garlic, and a sprinkle of nutmeg in a large bowl. The texture should be creamy yet thick enough to hold its shape. Take the time to blend the ingredients until they are well incorporated, ensuring that the flavors meld and the filling is consistent throughout.
Stuffing the Shells
When it comes to stuffing the shells, efficiency is key. Use a small spoon or a piping bag to fill each shell generously without overstuffing. If using a spoon, hold the shell upright and carefully spoon the filling in, allowing it to settle naturally. Filling them this way minimizes mess and ensures that each shell is filled to the brim. A well-stuffed shell will hold its shape during baking and provide a satisfying bite.
Layering with Sauce and Cheese
Layering your stuffed shells with sauce and cheese not only enhances the flavor but also elevates the presentation. Start by spreading a thin layer of marinara sauce on the bottom of your baking dish to prevent sticking. Place the stuffed shells seam-side up, and then generously cover them with more marinara sauce. Finish with a layer of shredded mozzarella and grated Parmesan cheese on top. This layering technique guarantees that every bite is bursting with flavor and the melted cheese creates a beautiful golden crust.
Covering and Baking
Cover the baking dish with aluminum foil to retain moisture, ensuring that the shells cook evenly without drying out. Bake at 375°F (190°C) for approximately 25 minutes. Then, remove the foil and continue baking for an additional 10-15 minutes. This final uncovered baking step allows the cheese to melt beautifully and develop a golden-brown color, adding an appealing texture and flavor to the dish.
Cooling and Garnishing
Let the Cheesy Spinach and Mushroom Stuffed Shells cool for about 5-10 minutes before serving. This cooling period allows the flavors to settle and makes it easier to serve. For an added touch of freshness and color, garnish the dish with fresh basil leaves. The aromatic herb complements the richness of the cheese and adds a vibrant visual appeal.
Serving Suggestions
To enhance your dining experience, consider serving the stuffed shells alongside a crisp green salad dressed with a light vinaigrette. Garlic bread also pairs beautifully, providing a delightful crunch and additional flavor. If you’re looking to elevate the meal further, a glass of white wine, such as Sauvignon Blanc or Pinot Grigio, can perfectly complement the dish’s rich and cheesy profile.
Nutritional Benefits
Cheesy Spinach and Mushroom Stuffed Shells are an excellent vegetarian delight, packed with protein from the cheeses and nutrients from the spinach and mushrooms. This dish serves as a well-rounded meal, offering a balance of carbohydrates, proteins, and vegetables. For those looking to customize, feel free to incorporate additional vegetables like bell peppers or zucchini, or even add protein options such as shredded chicken or tofu for a heartier version.
