2 tablespoons fresh italian parsley, finely chopped
½ teaspoon kosher salt
¼ teaspoon freshly ground black pepper
4 cloves garlic, grated
How to Make It
1. Step
Bring a large pot of salted water to a boil. Add the shells and cook according to the package instructions until al dente. Stir every few minutes to keep shells from sticking to the pot and to each other. Reserve 1¼ cups (300 ml) of the pasta cooking water, then drain the shells and run under cold water to stop the cooking. Set aside in a colander.
2. Step
Make the vodka sauce: Heat the olive oil in a large skillet over medium heat. Add the shallot and garlic and cook until softened, 6 minutes.
3. Step
Add the butter, tomato paste, and red pepper flakes. Stir until the tomato paste is incorporated, then cook for 5 minutes, or until the tomato paste turns a deep and rusty red color and begins to caramelize. Add the vodka and stir until the liquid evaporates, at least 2 minutes to ensure alcohol cooks off.
4. Step
Reduce the heat to low and slowly pour in the cream. Stir until the sauce is smooth and creamy
5. Step
Add ½ cup (120 ml) of the reserved pasta water and stir until combined, then add the Parmesan cheese in 1 cup (125 g) increments, stirring between each addition until fully incorporated. Add more pasta water as needed until the sauce is creamy. Season to taste with salt, if necessary. Remove the pan from the heat.
6. Step
Preheat the oven to 375°F (190*C).
7. Step
Stuff the shells: Add the egg, ricotta, 2 cups of mozzarella, the Parmesan, parsley, salt, black pepper, and garlic to a medium bowl and mix until well-combined. Transfer the filling to a quart-sized resealable bag and cut a ½-inch opening in the corner.
8. Step
Spoon two-thirds of the sauce into the bottom of a 9 x 13-inch baking dish.
9. Step
Carefully pipe the cheese filling into each shell, then place in the baking dish. Top with the remaining vodka sauce and remaining ¾ cup of mozzarella cheese. Cover the baking dish with foil.
10. Step
Bake the stuffed shells for 30 minutes, then remove the foil and bake for another 10 minutes, or until the cheese has melted.
