How to Make Spicy Zucchini and Pesto Cheese Stuffed Shells

1. Preheat the oven to 425 °F. Prepare a baking dish by lightly greasing it, or if you prefer, use an oven-safe skillet to skip the dish entirely.

2. Boil a large pot of salted water over high heat. Add the jumbo shells and cook until al dente according to the package instructions, about 10-12 minutes. Reserve 1 cup of the pasta cooking water; then drain the shells.

3. Cook the sausage and zucchini in a large skillet over medium heat, stirring until browned, about 5-8 minutes. Then, reduce the heat to low and mix in the tomato paste, thyme, and oregano. Cook for 1-2 minutes before adding the vodka. Simmer for 1 minute, then pour in the milk and 1/3 cup of the reserved pasta water. Season with salt and pepper, and let it simmer for 10 minutes until the sauce thickens slightly.

4. Mix together the ricotta, provolone, and 1/2 cup of the basil pesto in a medium bowl. This creamy mixture will be the heavenly filling for your shells.

5. Assemble the dish by spooning 3/4 of the sauce into the bottom of the greased baking dish. One by one, fill each jumbo shell with about 1 tablespoon of the cheese mixture and place it in the dish. Once filled, spoon the remaining sauce over the shells and drizzle with the rest of the pesto. Sprinkle torn mozzarella on top for a gooey finish.

6. Bake for 15-20 minutes, or until the cheese is melted and bubbly, creating a delightful golden topping. Serve warm, garnished with fresh basil for a beautiful touch. Enjoy these heavenly stuffed shells!

Optional: Garnish with extra basil or a sprinkle of red pepper flakes for an added kick.
