Instructions

Cook the mostaccioli according to the package directions until al dente. While your pasta cooks, warm the olive oil in a skillet over medium heat. Toss in the chopped onion and sauté until it softens, about 5 minutes, then stir in the garlic for a fragrant minute.

Next, lower the heat slightly and whisk in the pumpkin purée, cream, sage, and nutmeg. Let this creamy sauce simmer gently for a couple of minutes. Season the mixture with salt and black pepper, and fold in the Parmesan cheese plus half of the shredded mozzarella. The goal is a thick, spoonable sauce that clings to the noodles.

Drain the pasta, place it into a lightly greased baking dish, and pour the pumpkin-sage sauce over top. Stir well to coat every piece, then sprinkle with the remaining mozzarella. Slide the dish into a preheated oven at 375°F (190°C) and bake for about 20 minutes, or until the cheese is melted and golden in spots. Let it rest just a moment before digging in.

This luxurious yet comforting gratin sings with the earthy goodness of pumpkin and sage. It’s a must-try if you love fall flavors or just want a hearty, family-friendly dinner that’s easily adaptable—swap in gluten-free pasta if needed, or add sautéed mushrooms or Italian sausage for extra oomph. Whether you’re cooking for a special gathering or a simple evening at home, this is one of those recipes everyone can snuggle up with all season long. Enjoy!
