Pumpkin Gouda Stuffed Shells

The smell of brown butter and sage hit me the second I walked into my friend's kitchen last October, and I knew I was in trouble. She was testing this recipe for a dinner party, and the way those crisped sage leaves were scattered over golden, bubbling shells made me immediately ask for the recipe before I'd even tasted it. One bite of that creamy pumpkin filling with the smoky Gouda, all draped in nutty Alfredo, and I was planning my own dinner party in my head. I've made these shells at least a dozen times since, and they never fail to make people lean back in their chairs and sigh happily.

I served these at Thanksgiving two years ago as a vegetarian main, and my uncle, a devoted meat eater, went back for thirds. He kept saying he didn't understand how something without meat could be this filling, this flavorful, this good. My cousin snuck into the kitchen later and ate two cold shells straight from the pan. That's when I knew this recipe had real power.

Ingredients

• Jumbo pasta shells: Cook them just shy of al dente or they'll tear when you stuff them, I learned this the hard way with a pile of broken shells on my counter.
• Pumpkin puree: Make sure it's unsweetened, not pie filling, the filling needs to be savory and creamy, not dessert sweet.
• Smoked Gouda cheese: This is the secret star, it brings a smoky, nutty depth that regular Gouda just can't match.
• Whole milk ricotta cheese: The creaminess here balances the pumpkin and keeps the filling from being too dense or dry.
• Parmesan cheese: Freshly grated is key, the pre shredded stuff doesn't melt as smoothly into the Alfredo.
• Fresh sage: Both in the filling and crisped in the butter, sage and pumpkin are autumn soulmates.
• Nutmeg: Just a little bit, freshly grated if you have it, adds warmth without making it taste like pumpkin pie.
• Unsalted butter: You need control over the salt, and browning butter is easier when you start unsalted.
• Heavy cream: This makes the Alfredo silky and rich, you can lighten it slightly with half and half, but don't skip the cream entirely.
• Garlic: A little goes a long way in the Alfredo, it should support the sage and brown butter, not overpower them.

Instructions

Preheat and prep your dish:

Get your oven to 375 degrees and grease a 9x13 inch baking dish so nothing sticks. This step sets you up for an easy assembly later.

Boil and cool the shells:

Cook the shells in well salted water until just barely al dente, a minute or two less than the box says. Drain, rinse under cool water, and lay them out on a lightly oiled tray so they don't glue themselves together.

Make the pumpkin filling:

Mix pumpkin, ricotta, smoked Gouda, Parmesan, egg, sage, nutmeg, garlic, salt, pepper, and cayenne in a big bowl until smooth and creamy. If it feels stiff, stir in a splash of cream or milk to loosen it up, then taste and adjust the seasoning.

Brown the butter with sage:

Melt butter in a medium saucepan over medium heat, add sage leaves, and swirl until the butter foams, browns, and smells like toasted hazelnuts, about 4 to 6 minutes. Lift out the sage leaves and set them aside on paper towels, they'll crisp up and become a gorgeous garnish.

Build the Alfredo sauce:

Return the brown butter to low heat, add garlic, and cook until fragrant, about 30 to 60 seconds. Stir in the heavy cream and bring it to a gentle simmer.

Finish the Alfredo:

Lower the heat and whisk in Parmesan gradually, letting each handful melt before adding more. Season with nutmeg, salt, and pepper, and if it's too thick, whisk in a little broth until it's pourable but still creamy.

Sauce the baking dish:

Spread about half to three quarters of a cup of Alfredo on the bottom of your prepared dish. This keeps the shells from sticking and adds flavor to every bite.

Stuff the shells:

Spoon 2 to 3 tablespoons of pumpkin filling into each shell and arrange them open side up in a snug single layer in the dish. Take your time, it's oddly satisfying.

Pour and top:

Pour most of the remaining Alfredo over and around the shells, then scatter the shredded Gouda, Parmesan, and crisped sage over the top. Save a little Alfredo for drizzling after baking if you want.

Bake covered, then uncovered:

Cover loosely with foil, tenting it so it doesn't stick to the cheese, and bake for 20 minutes. Remove the foil and bake another 10 to 15 minutes until bubbling and golden, if you want more color, broil for 1 to 3 minutes but watch it closely.

Rest and garnish:

Let the dish rest for 5 to 10 minutes so the sauce thickens slightly and the shells settle. Drizzle with reserved Alfredo, add fresh or crisped sage, black pepper, and extra Parmesan.

Serve warm:

Plate 3 to 4 shells per person and serve with a green salad, roasted vegetables, or crusty bread for mopping up that sauce.

Save to Pinterest

The first time I brought these to a potluck, I watched a quieter friend go back three times, and each time she'd close her eyes for a second after the first bite. She told me later it reminded her of her grandmother's kitchen in the fall, even though her grandmother never made anything like this. That's the thing about food, it doesn't have to be exact to feel like home.

Make Ahead and Storage

I assemble these the night before all the time, cover the dish tightly with plastic wrap, and refrigerate it until I'm ready to bake. Just add 10 to 15 minutes to the baking time if you're starting from cold. You can also freeze the whole unbaked dish, wrapped well, for up to two months, thaw it overnight in the fridge before baking. Leftovers reheat beautifully in a low oven covered with foil, or even in the microwave if you're in a hurry, though the oven keeps the shells from getting rubbery.

Flavor Variations

If smoked Gouda feels too bold, use half smoked and half regular Gouda, or swap in fontina for something milder and melty. I've also made this with butternut squash puree instead of pumpkin, and it's just as good, maybe even a little sweeter. A tiny pinch of cinnamon or allspice in the filling adds warmth without crossing into dessert territory. For a heartier version, fold in sauteed mushrooms or crumbled cooked sausage, my brother in law does this and swears by it.

Serving Suggestions

These shells are rich, so I like to serve them with something bright and crisp on the side. A simple arugula salad with lemon vinaigrette cuts through the creaminess perfectly. Roasted Brussels sprouts or green beans with garlic are great too. And crusty bread is non negotiable, you'll want something to soak up every last bit of that brown butter Alfredo.

• Pair with a dry white wine like Chardonnay or a light Pinot Noir.
• Garnish with extra crisped sage and a dusting of Parmesan right before serving.
• If you have leftover Alfredo, toss it with pasta the next day, it's a gift that keeps giving.

This dish has become my go to when I want to feed people something that feels special but doesn't require me to stress in the kitchen all day. It's cozy, it's impressive, and it tastes like you put in way more effort than you actually did.

Recipe FAQs

→ Can I make this dish ahead of time?

Yes, you can assemble the stuffed shells up to 24 hours in advance and refrigerate them. Cover tightly with foil and add 10–15 minutes to the baking time if baking straight from the fridge.

→ Can I freeze stuffed shells?

Absolutely. Assemble the dish without baking, wrap tightly in plastic wrap and foil, and freeze for up to 2 months. Thaw overnight in the refrigerator before baking as directed.

→ What can I substitute for smoked Gouda?

If you prefer a milder flavor, use half smoked and half regular Gouda, or substitute with sharp cheddar, Gruyère, or fontina cheese for a different flavor profile.

→ How do I prevent the shells from sticking together?

After draining, rinse the cooked shells under cool water and lay them on a lightly oiled baking sheet or tray. This keeps them separated and easy to fill.

→ Can I use fresh pumpkin instead of canned?

Yes, homemade pumpkin purée works wonderfully. Roast pumpkin or sugar pumpkin until tender, then blend until smooth. Make sure to drain excess liquid for the best consistency.

→ How do I know when the brown butter is ready?

Watch for a nutty aroma and golden-brown specks at the bottom of the pan. The butter will foam, then settle. This takes about 4–6 minutes over medium heat. Don't let it burn.

→ Can I lighten the Alfredo sauce?

Yes, you can substitute half the heavy cream with whole milk or half-and-half. The sauce will be slightly thinner but still creamy and delicious.
