Instructions

  1. Step
    Bring a large pot of generously salted water to a boil. Cook the jumbo shells until al dente, about 2 minutes less than the package directions. Drain and rinse under cold water. Set aside. ​
  2. Step
    In a large skillet or Dutch oven, melt the butter over medium heat. Add the chopped onion and cook for 4–5 minutes, until softened. Add the ground beef and cook until browned, breaking it into small crumbles. Stir in the garlic, oregano, fennel seeds, smoked paprika, crushed red pepper flakes, salt and black pepper. Cook for 1 minute, until fragrant. Pour in the marinara sauce and stir to combine. Add the milk and mix until fully incorporated. Bring to a gentle simmer and cook for 8–10 minutes, stirring occasionally, until the sauce is rich and creamy. Remove from the heat. ​
  3. Step
    In a medium bowl, combine the pumpkin purée, shredded cheddar cheese, mozzarella cheese (if using), fresh sage and pumpkin spice. Mix until smooth and creamy. ​
  4. Step
    Preheat the oven to 375°F (190°C). Spread about 1½ cups of the creamy beef marinara over the bottom of a 9 × 13-inch (23 × 33 cm) baking dish. Fill each cooked shell with about 2 tablespoons of the pumpkin cheese mixture and arrange them in the baking dish. Spoon the remaining beef marinara over the shells, making sure they are well coated. Top with an additional ½–1 cup (50–100 g) shredded cheddar cheese, if desired, for an extra cheesy finish. ​
  5. Step
    Cover with foil and bake for 25 minutes. Remove the foil and continue baking for 10–15 minutes, until the cheese is melted, bubbly and lightly golden. ​
  6. Step
    Let the shells rest for 5–10 minutes before serving. Garnish with extra chopped fresh sage, grated Parmesan cheese if desired, and freshly cracked black pepper. Serve with garlic bread and a crisp green salad. ​
