Step‑by‑Step Instructions for Easy and Healthy Vegetarian Stuffed Pasta Shells
Step 1: Preheat Oven
Begin by preheating your oven to 180°C (350°F). This essential step ensures that your Easy and Healthy Vegetarian Stuffed Pasta Shells bake evenly, resulting in a delightful, melty cheese topping. While the oven heats, gather your ingredients and get the pasta water boiling.
Step 2: Cook Pasta Shells
In a large pot of boiling salted water, cook the pasta shells according to package instructions, usually around 8–10 minutes. Aim for al dente, as they will continue cooking in the oven. Once cooked, drain the shells and toss them with a drizzle of olive oil to prevent sticking. Set aside to cool slightly.
Step 3: Prepare Spinach
In a medium skillet, add a splash of water and bring it to a simmer over medium heat. Add the fresh spinach, cooking until wilted, which takes about 2–3 minutes. Carefully drain the spinach, then squeeze out any excess moisture to avoid a watery filling in your vegetarian stuffed pasta shells.
Step 4: Make Filling
In a bowl, combine the creamy mascarpone cheese with your wilted spinach and a generous pour of red pepper sauce for flavor. Mix until well-blended, ensuring the filling is rich and flavorful. Gently stuff each cooled pasta shell with the mixture, packing it in without breaking the shells.
Step 5: Make Sauce
In a sauté pan, heat two tablespoons of olive oil over medium heat. Add finely chopped onion and minced garlic, cooking until fragrant and translucent, about 5 minutes. Stir in the dried thyme, oregano, and rosemary, allowing the herbs to release their aromas before adding tomato passata and vegetable stock. Let this simmer for 10 minutes, thickening slightly.
Step 6: Assemble Dish
Spread a layer of the rich red pepper sauce across the bottom of your baking dish, creating a flavorful base. Carefully arrange the stuffed pasta shells on top of the sauce, ensuring each shell is nestled comfortably. Sprinkle shredded mozzarella generously over the stuffed shells for an irresistible cheesy crust.
Step 7: Bake
Place your assembled dish in the preheated oven and bake for 15 minutes. You’ll know it’s ready when the cheese is bubbly and lightly golden, creating a lovely contrast against the vibrant sauce. Allow to cool for a few minutes before serving these delightful Easy and Healthy Vegetarian Stuffed Pasta Shells.
