Ingredients You’ll Need
This recipe is broken down into three parts: the squash filling, the sauce, and the assembly.
For the Roasted Squash:

- 1 tablespoon olive oil
- 1/2 teaspoon salt
- 1/4 teaspoon black pepper
For the Shells & Filling:
- 1 box (12 oz) jumbo pasta shells
- 1 cup whole milk ricotta cheese (full fat is best for creaminess)
- 1/2 cup grated Parmesan cheese, plus extra for topping
- 1 large egg, lightly beaten
- 1 teaspoon dried sage (this is the secret weapon!)
- 1/2 teaspoon garlic powder
- Salt and pepper to taste
- 1/2 cup shredded mozzarella cheese (for the filling)
For the Sauce & Topping:
- 1 jar (24 oz) good quality marinara sauce (or homemade)

- 1 cup shredded mozzarella cheese (for topping)
- Fresh parsley or basil, chopped, for garnish
Step-by-Step Baking Magic
Let’s get cooking! It’s easier than it looks, I promise.
Step 1: Roast the Squash
1. Preheat your oven to 400°F (200°C).
2. Toss the cubed butternut squash with 1 tablespoon of olive oil, salt, and pepper. Spread it in a single layer on a baking sheet.
3. Roast for 25–30 minutes, or until fork-tender and slightly caramelized.
4. Once cooled slightly, transfer the roasted squash to a large bowl. Mash it with a fork or pulse briefly in a food processor until mostly smooth but still slightly chunky for texture. You should have about 2 cups of puree.
Step 2: Cook the Shells
1. While the squash roasts, bring a large pot of salted water to a boil.
2. Add the jumbo shells and cook according to package directions, subtracting 2 minutes from the suggested time (we want them al dente since they will bake later).
3. Drain the shells and rinse immediately with cold water to stop the cooking process and prevent sticking. Set aside.
Step 3: Create the Filling
1. In the bowl with the mashed butternut squash, add the ricotta cheese, 1/2 cup Parmesan, the beaten egg, dried sage, garlic powder, salt, and pepper. Mix everything thoroughly until it’s a uniform, thick mixture.
2. Gently fold in the 1/2 cup of mozzarella cheese. Taste it! Does it need more salt? More sage? Adjust now.
Step 4: Assemble and Sauce
1. Reduce your oven temperature to 375°F (190°C).
2. In a 9×13 inch baking dish, spread about 1 cup of your marinara sauce across the bottom. If using heavy cream, swirl the cream into the remaining marinara sauce to create a pink sauce base. Spread half of this sauce mixture over the bottom of the dish.
3. Take each cooked shell and carefully stuff it with a generous spoonful of the butternut squash filling. Don’t be shy—heap it up!
4. Arrange the stuffed shells snugly in the prepared baking dish.
5. Pour the remaining sauce mixture evenly over the top of the shells.
6. Sprinkle the remaining 1 cup of mozzarella cheese and a little extra Parmesan over everything.
Step 5: Bake to Perfection
1. Cover the baking dish tightly with aluminum foil.
2. Bake for 25 minutes.
3. Remove the foil and bake for another 10–15 minutes, or until the cheese is bubbly and golden brown.
4. Let the shells rest for 5–10 minutes before serving. Garnish with fresh herbs!
Serving Suggestions
These shells are rich and delicious on their own, but they pair wonderfully with a crisp side salad dressed in a bright lemon vinaigrette. A slice of crusty Italian bread is perfect for scooping up any leftover sauce!
Tips for Customization and Variations
Want to tweak this recipe? I encourage it!
- Add Some Crunch: Stir 1/4 cup of toasted pine nuts or finely chopped walnuts into the squash filling for added texture.
- Make it Spicy: Add a pinch of red pepper flakes to the squash mixture or use a spicy arrabbiata marinara sauce.
- Swap the Cheese: Swap out the mozzarella topping for provolone for a tangier, meltier crust, or use Gruyère for a deeper, nuttier flavor.
- Use Different Squash: If you’re in a rush, you can substitute the roasted butternut squash with 2 cups of canned pumpkin puree, but you might need to slightly reduce the liquid/cream in the sauce, as canned pumpkin is wetter than roasted squash.

Frequently Asked Questions (FAQs)
Can I make this vegan?
Absolutely! To make this vegan, swap the ricotta for a cashew cream cheese base or use a store-bought vegan ricotta substitute. Replace the egg with 1 tablespoon of flaxseed mixed with 3 tablespoons of water (a flax egg). Use vegan mozzarella and Parmesan alternatives, and ensure your marinara sauce is dairy-free.
How far in advance can I assemble the shells?
You can stuff the shells and place them in the baking dish up to 24 hours ahead of time. Keep the dish covered tightly in the refrigerator. When ready to bake, you may need to add about 10-15 minutes to the initial covered baking time to ensure they heat through properly.
What if I don’t like sage?
Sage is traditional with squash, but if it’s not your favorite, you can swap it out! Try using 1 teaspoon of dried thyme and 1/2 teaspoon of dried rosemary for a more Italian herb profile, or a pinch of nutmeg for warmth.
