I stumbled upon the idea of butternut squash stuffed shells completely by accident during a particularly abundant fall harvest. I had been making traditional meat-filled shells for years, but wanted something lighter yet still satisfying for a vegetarian friend coming to dinner. The moment I tasted roasted butternut squash blended with ricotta, I knew this was going to be special. The squash brings this natural sweetness and velvety texture that makes the filling incredibly luxurious without being heavy. What really makes this recipe sing is the sage cream sauce – it's not your typical marinara or basic white sauce. The sage infuses into the cream while it reduces, creating this aromatic, slightly earthy flavor that pairs perfectly with the sweet squash. When you bake everything together, the shells absorb some of that sauce, the cheese on top gets gorgeously golden, and those sage leaves turn crispy like little herby chips. The first time I served these, the table went silent for a good minute – everyone was too busy savoring to talk. That's when I knew this recipe was a keeper. It's become my most requested dish every fall season.
Why I love this recipe
I love this recipe because it proves that vegetarian dishes can be just as comforting and impressive as their meat-based counterparts. There's something deeply satisfying about the sweet-savory balance here – the butternut squash brings natural sweetness, the ricotta adds tang and creaminess, and the sage provides that earthy, aromatic note that grounds everything. The texture contrast is perfect too: tender pasta, creamy filling, silky sauce, and those crispy sage leaves on top. What really wins me over is how this dish makes my home smell absolutely incredible while it's baking. That combination of roasted squash, browning cheese, and sage creates an aroma that says "autumn" better than any candle ever could. I also appreciate that this recipe looks incredibly impressive but isn't actually difficult to make – it's all about good timing and assembly. The make-ahead potential is another huge plus; you can stuff the shells and refrigerate them, then just pop them in the oven when you're ready to eat. It's become my go-to dish for potlucks and dinner parties because it feeds a crowd, accommodates vegetarians, and always gets rave reviews. Every time I make it, I fall in love with cooking all over again.
What You Need From Your Kitchen
- Butternut Squash: Roast until tender and puree until smooth for the sweet base of your filling
- Ricotta Cheese: Provides creamy texture and tangy flavor that balances the sweet squash
- Jumbo Pasta Shells: Cook al dente and drain well to hold the generous filling
- Heavy Cream: Simmer with garlic and sage to create the luxurious sauce base
- Fresh Sage Leaves: Infuse into cream sauce and arrange on top for crispy aromatic garnish
- Mozzarella Cheese: Divide between filling and topping for melty, golden perfection
- Parmesan Cheese: Add to filling and sprinkle on top for nutty, salty depth
Let's Make These Together
- Roast the Squash
- Begin by preparing your butternut squash if you haven't already. Cube the squash into one-inch pieces and toss with olive oil, salt, and pepper. Roast at 400°F for about 25-30 minutes until fork-tender and slightly caramelized. Once cooled, blend until you have a smooth, velvety puree. This roasted puree is the star of your filling and brings incredible depth of flavor.
- Cook Pasta Perfectly
- Bring a large pot of salted water to a rolling boil and cook your jumbo shells according to package directions, but aim for al dente – they'll continue cooking in the oven. Drain them carefully and lay them out on an oiled baking sheet so they don't stick together. This step is crucial because torn shells are harder to fill.
- Create Creamy Filling
- In a large mixing bowl, combine your butternut squash puree with ricotta cheese, half your shredded mozzarella, half the parmesan, a pinch of nutmeg, and season generously with salt and pepper. Mix everything together until completely smooth and creamy. The filling should taste incredible on its own – go ahead and sneak a taste to make sure the seasoning is perfect.
- Prepare Sage Sauce
- In a saucepan, gently warm your heavy cream over medium heat with minced garlic and several fresh sage leaves. Let this simmer very gently for about 5-7 minutes, stirring occasionally, until the cream has thickened slightly and absorbed all that gorgeous sage flavor. Remove the sage leaves and pour half of this aromatic cream into the bottom of your baking dish.
- Stuff and Arrange
- Now comes the fun part – filling your shells. Using a spoon or piping bag, generously fill each cooled shell with your butternut squash mixture. Don't be shy here; these shells should be packed full. Arrange each stuffed shell snugly in your baking dish on top of that cream sauce. They should fit together like little pillows.
- Final Assembly and Bake
- Pour your remaining sage cream sauce over all the stuffed shells, making sure they're well-coated. Sprinkle with the remaining mozzarella and parmesan cheese, then arrange fresh sage leaves artistically on top. Drizzle everything with a bit of olive oil. Cover with foil and bake at 375°F for 25 minutes, then remove the foil and bake another 20 minutes until gloriously golden, bubbly, and those sage leaves are perfectly crispy.

Switch Things Up
I first made these stuffed shells on a chilly October evening when I had way too much butternut squash from the farmer's market and needed to get creative. I was skeptical about stuffing pasta with squash at first – would it be too sweet? Too heavy? But the moment I mixed that roasted squash with ricotta and tasted it, I knew I was onto something special. The filling was so creamy and perfectly balanced that I may have eaten a few spoonfuls before even stuffing the shells. When they came out of the oven with that bubbly golden top and those crispy sage leaves, my kitchen smelled like an Italian countryside villa. My family devoured them, and my kids who normally turn their noses up at squash asked for seconds. Since then, I've made these shells countless times, tweaking the recipe here and there, but the core magic remains the same. It's become my signature fall dish, and honestly, I start craving them the moment September hits.
Perfect Pairings
These stuffed shells pair beautifully with a crisp arugula salad dressed in lemon vinaigrette to cut through the richness of the cream sauce. A glass of Chardonnay or Pinot Grigio complements the butternut squash's natural sweetness perfectly. For a heartier meal, serve alongside garlic bread or focaccia to soak up every last bit of that sage cream sauce. Roasted Brussels sprouts or green beans almondine make excellent vegetable sides that echo the autumn theme. If you're feeding a crowd, start with a butternut squash soup as an appetizer to really commit to the seasonal vibe.

Frequently Asked Questions
- → Can I use frozen butternut squash for this recipe?
Yes, you can use frozen butternut squash cubes. Roast them according to package directions, then drain any excess liquid before pureeing. Fresh squash typically has better flavor and texture, but frozen works in a pinch.
- → How do I prevent the pasta shells from tearing?
Cook the shells just to al dente – slightly undercooked is better than overcooked. Drain them gently and immediately lay them out on an oiled surface. Handle them carefully when filling, supporting the shell with one hand while spooning filling with the other.
- → Can I make this recipe ahead of time?
Absolutely! You can assemble the entire dish up to 24 hours in advance and refrigerate covered. When ready to bake, add an extra 10 minutes to the covered baking time since you're starting from cold. You can also freeze unbaked stuffed shells for up to 3 months.
- → What can I substitute for heavy cream?
For a lighter option, use half-and-half or a combination of whole milk and a tablespoon of flour to help thicken the sauce. Coconut cream works for dairy-free versions, though it will add a slight coconut flavor.
- → My sage leaves didn't get crispy, what went wrong?
Make sure you're using fresh sage leaves and that you drizzle them lightly with olive oil before baking. They need the uncovered baking time to crisp up, so don't skip removing the foil for the last 20 minutes. If they're still not crispy, you can quickly fry fresh sage in a bit of butter and add them as garnish after baking.
- → Can I add protein to this vegetarian dish?
Definitely! Crumbled Italian sausage, ground turkey, or shredded rotisserie chicken mixed into the filling would be delicious. Just cook the protein first and drain any excess fat before mixing with the squash and ricotta.
- → How do I store and reheat leftovers?
Store leftover stuffed shells in an airtight container in the refrigerator for up to 4 days. Reheat individual portions in the microwave for 2-3 minutes, or reheat the entire dish covered with foil in a 350°F oven for about 20 minutes until heated through.
