How to Make Cheesy Spinach and Mushroom Stuffed Shells

Now that you have all your ingredients ready, let’s dive into making these delightful Cheesy Spinach and Mushroom Stuffed Shells. Follow these simple steps, and you’ll have a delicious meal that’s sure to impress!

Step 1: Preheat the Oven

First things first, preheat your oven to 375°F (190°C). Preheating is crucial because it ensures even cooking. You want those cheesy shells to bake perfectly, so don’t skip this step!

Step 2: Cook the Pasta Shells

Next, bring a large pot of salted water to a boil. Add the large pasta shells and cook them according to the package instructions until they are al dente. This usually takes about 8-10 minutes. Remember, you want them firm enough to hold the filling without breaking. Once done, drain and set them aside to cool.

Step 3: Sauté the Vegetables

In a skillet, heat a splash of olive oil over medium heat. Add the minced garlic and diced mushrooms. Sauté them for about 3-4 minutes until the mushrooms are softened and fragrant. Then, toss in the chopped spinach and cook until it wilts, which should take another 2 minutes. This step adds a wonderful depth of flavor to your filling!

Step 4: Prepare the Cheese Mixture

In a large mixing bowl, combine the ricotta, shredded mozzarella, grated Parmesan, and the sautéed vegetable mixture. Crack in the egg and sprinkle in the Italian seasoning, salt, and pepper. Mix everything together until well combined. This cheesy mixture is the heart of your stuffed shells!

Step 5: Stuff the Shells

Now comes the fun part! Take each pasta shell and gently stuff it with the cheese and spinach mixture. Use a spoon or your fingers to pack it in, but be careful not to break the shells. A heaping tablespoon per shell usually does the trick. It’s okay if some filling peeks out; it just adds to the charm!

Step 6: Assemble the Dish

Grab a baking dish and spread half of the marinara sauce on the bottom. This prevents the shells from sticking. Place the stuffed shells in the dish, open side up, and pour the remaining marinara sauce over them. Make sure they’re well coated; this keeps them moist while baking.

Step 7: Bake the Dish

Cover the baking dish with foil and pop it in the preheated oven. Bake for 25 minutes. After that, remove the foil and bake for an additional 10 minutes. This uncovered baking allows the cheese to bubble and turn golden brown. Let the dish cool for a few minutes before serving. Your Cheesy Spinach and Mushroom Stuffed Shells are now ready to be devoured!

Tips for Success

Use a large pot for boiling pasta to prevent sticking.
Don’t overcook the pasta; it should be al dente for easy stuffing.
Let the sautéed vegetables cool slightly before mixing with cheese.
For extra flavor, add a pinch of red pepper flakes to the cheese mixture.
Make it ahead of time and refrigerate before baking for a quick dinner option.

Equipment Needed

Large pot: For boiling pasta. A deep skillet can work too.
Skillet: For sautéing vegetables. A saucepan is a good alternative.
Baking dish: A 9×13 inch dish is ideal, but any oven-safe dish will do.
Mixing bowl: Use any large bowl for combining ingredients.
Spoon: For stuffing shells. A small cookie scoop can make it easier!

Variations

Meat Lover’s Delight: Add cooked ground turkey or sausage to the cheese mixture for a heartier dish.
Spicy Kick: Mix in some diced jalapeños or a dash of hot sauce for a spicy twist.
Herb Infusion: Experiment with fresh herbs like basil or parsley for a burst of flavor.
Gluten-Free Option: Use gluten-free pasta shells to make this dish suitable for gluten-sensitive eaters.
Vegan Version: Substitute ricotta with tofu blended with nutritional yeast and use vegan cheese.

Serving Suggestions

Side Salad: Pair with a fresh garden salad drizzled with balsamic vinaigrette for a light touch.
Garlic Bread: Serve with warm garlic bread to soak up the delicious marinara sauce.
Wine Pairing: A glass of Chardonnay complements the cheesy flavors beautifully.
Presentation: Garnish with fresh basil or parsley for a pop of color.

FAQs about Cheesy Spinach and Mushroom Stuffed Shells

Can I make Cheesy Spinach and Mushroom Stuffed Shells ahead of time?

Absolutely! You can prepare the stuffed shells in advance and store them in the refrigerator. Just cover the baking dish tightly with foil. When you’re ready to bake, add a few extra minutes to the cooking time.

What can I substitute for ricotta cheese?

If you’re looking for a lighter option, cottage cheese works well. For a vegan alternative, blend silken tofu with nutritional yeast to mimic the creamy texture of ricotta.

Can I freeze the stuffed shells?

Yes, these Cheesy Spinach and Mushroom Stuffed Shells freeze beautifully! Just assemble them in a freezer-safe dish, cover tightly, and freeze. When you’re ready to enjoy, thaw overnight in the fridge and bake as directed.

What other vegetables can I add to the filling?

You can get creative! Bell peppers, zucchini, or even artichoke hearts can add flavor and texture. Just make sure to sauté them until tender before mixing with the cheese.

How do I know when the stuffed shells are done baking?

Look for bubbly cheese and a golden top. The edges of the marinara sauce should be slightly caramelized. Let them cool for a few minutes before serving to allow the flavors to meld.
