Ingredients You’ll Need

Pasta and Cheese Filling

• Jumbo pasta shells
  • Use 20 to 24 shells, plus a few extra in case some tear.
  • Barilla, De Cecco, or store brand all work well.
• Whole milk ricotta cheese
  • Use full-fat ricotta for the creamiest filling.
  • Drain off any excess liquid if it looks watery.
• Shredded mozzarella cheese
  • Low-moisture, part-skim melts nicely and browns well.
• Grated Parmesan cheese
  • Freshly grated tastes best, but pre-grated from the refrigerated section works in a pinch.
• Egg
  • Helps bind the filling so it stays inside the shells.
• Fresh spinach, chopped
  • Use baby spinach or frozen spinach (thawed and squeezed very dry).
• Garlic, minced
• Fresh basil or flat-leaf parsley, chopped
• Kosher salt and freshly ground black pepper
• Pinch of red pepper flakes (optional, for a little heat)
• Freshly grated nutmeg (optional, but amazing with ricotta and pumpkin)

Pumpkin Cream Sauce

• Canned pumpkin puree
  • Use 100% pumpkin, not pumpkin pie filling.
  • Libby’s or store brand both work.
• Heavy cream
  • You can swap half-and-half for a slightly lighter sauce.
• Chicken broth or vegetable broth
  • Low-sodium gives you better control over seasoning.
• Unsalted butter or olive oil
• Yellow onion, finely chopped
• Garlic, minced
• Fresh sage leaves, chopped
  • Dried sage works if you do not have fresh; use about one-third the amount.
• Ground cinnamon, just a pinch
• Ground black pepper
• Kosher salt
• Grated Parmesan cheese, for the sauce
• Lemon juice or apple cider vinegar
  • Just a splash to brighten the sauce at the end.

Optional Toppings

• Extra shredded mozzarella
• Extra grated Parmesan
• Fresh herbs for garnish
• Toasted breadcrumbs for crunch

Pantry Shortcuts

• Use jarred minced garlic if you do not want to chop.
• Use pre-shredded mozzarella and pre-grated Parmesan to save time.
• Use frozen chopped spinach instead of fresh to skip washing and chopping.

Equipment List

• Large pot for boiling pasta
• Large skillet or wide saucepan for the pumpkin cream sauce
• Mixing bowl for the cheese filling
• 9×13 inch baking dish (or similar size)
• Measuring cups and spoons
• Whisk and wooden spoon or silicone spatula
• Colander
• Foil for covering the baking dish

Tips & Tricks

• Boil extra shells, since a few usually tear while cooking.
• Cook the pasta just to very firm al dente, since it finishes cooking in the oven.
• Salt the pasta water generously so the shells taste seasoned from the inside out.
• Drain ricotta if it looks watery, or the filling can turn runny.
• Squeeze frozen spinach very dry in a clean kitchen towel to avoid watery filling.
• Taste the ricotta filling before you add the egg so you can adjust salt and pepper.
• Warm the pumpkin cream sauce gently and whisk often so it stays smooth and silky.
• Add broth gradually to the sauce until it reaches a pourable but slightly thick consistency.
• Spread a thin layer of pumpkin cream sauce on the bottom of the baking dish so the shells do not stick.
• Stuff the shells generously but do not overfill, or they can burst while baking.
• Cover the dish with foil for most of the bake time to keep the shells moist.
• Remove the foil at the end so the cheese on top browns and bubbles.
• Let the baked shells rest 10 minutes before serving so the sauce thickens slightly.
• Double the recipe and bake in two pans if you want leftovers or plan to freeze one.
• Add cooked crumbled Italian sausage or shredded rotisserie chicken if you want extra protein.

How to Make Stuffed Shells With Pumpkin Cream Sauce

Step 1: Cook the Pasta Shells

Bring a large pot of well-salted water to a boil. Add the jumbo shells and cook until very firm al dente, usually 1 to 2 minutes less than the package suggests. Stir occasionally so the shells do not stick together.

Drain the shells and rinse them briefly under cool water to stop the cooking. Lay them out on a lightly oiled baking sheet or plate so they do not clump. Set them aside while you mix the filling and sauce.

Step 2: Mix the Ricotta and Spinach Filling

In a large mixing bowl, add ricotta, shredded mozzarella, grated Parmesan, chopped spinach, minced garlic, herbs, salt, pepper, red pepper flakes, and nutmeg if you use it. Stir until everything looks evenly combined and creamy. Taste a small spoonful and adjust salt and pepper to your liking.

Add the egg and stir again until the filling looks smooth and thick. The mixture should hold its shape on a spoon. If it looks too stiff, add a splash of cream or milk; if it looks loose, add a little more Parmesan.

Step 3: Sauté Aromatics for the Pumpkin Cream Sauce

Heat butter or olive oil in a large skillet over medium heat. Add the chopped onion and cook until it turns soft and lightly golden around the edges, about 6 to 8 minutes. Stir often so it does not burn.

Add the minced garlic and chopped sage and cook about 1 minute, until the kitchen smells amazing. Sprinkle in a tiny pinch of cinnamon, salt, and pepper. Stir everything together.

Step 4: Build the Pumpkin Cream Sauce

Whisk in the canned pumpkin puree and stir until it coats the onions and herbs. Pour in the broth gradually while you whisk, until the mixture loosens into a thick, smooth sauce. Let it bubble gently for 3 to 4 minutes so the flavors blend.

Pour in the heavy cream and whisk again until the sauce turns velvety and slightly lighter in color. Add grated Parmesan and stir until it melts into the sauce. Taste and adjust salt, pepper, and sage, then add a small splash of lemon juice or apple cider vinegar to brighten the flavor.

Step 5: Assemble the Stuffed Shells

Preheat your oven to 375°F. Spread a generous layer of pumpkin cream sauce over the bottom of your baking dish. You want enough to fully cover the surface so the shells sit in a cozy sauce bath.

Fill each shell with a heaping spoonful of the ricotta mixture. Nestle the stuffed shells into the sauced baking dish, open side up, snug but not smashed together. Spoon more pumpkin cream sauce over the top of the shells, then sprinkle with extra mozzarella and Parmesan if you like a cheesy crust.

Step 6: Bake Until Bubbly and Golden

Cover the baking dish tightly with foil. Bake at 375°F for about 20 minutes, until the sauce bubbles around the edges. Remove the foil and bake another 10 to 15 minutes, until the cheese on top looks melted and lightly browned.

Let the stuffed shells rest on the counter for about 10 minutes before serving. This short rest helps the sauce thicken slightly and makes the shells easier to scoop. Sprinkle with fresh herbs and a little extra Parmesan right before you bring the dish to the table.

What to Serve with Stuffed Shells With Pumpkin Cream Sauce

Serve these Stuffed Shells With Pumpkin Cream Sauce with a crisp green salad, like mixed greens with lemony vinaigrette, to balance the richness. Garlic bread or warm focaccia makes a perfect side, since everyone loves extra bread to swipe through the pumpkin sauce. Steamed or roasted vegetables like broccoli, green beans, or Brussels sprouts add color and texture. A simple sparkling water with citrus slices or apple cider over ice pairs nicely and keeps the meal family friendly.

Storage Options

• Store leftovers in an airtight container in the fridge for up to 4 days.
• Reheat single portions in the microwave with a splash of milk or broth, covered, until hot and creamy.
• Reheat a full pan in the oven at 350°F, covered with foil, until warmed through, then uncover for a few minutes to re-melt the cheese.
• Freeze baked shells tightly wrapped for up to 2 months, then thaw overnight in the fridge and reheat in the oven with a little extra sauce or broth if they look dry.
