How to cook Butternut Squash Stuffed Shells

Creamy, tangy, and with a caramelized sweetness from roasted butternut squash, this stuffed shells recipe is one you’re sure to love. In lieu of any ricotta, Parmesan, or mozzarella cheese, I stuff them with a light, dairy-free “ricotta.” Made from cashew cream, crumbled tofu, herbs, and lemon zest, it’s rich and flavorful. If your family is squeamish about tofu, just don’t tell them. They’ll never suspect it here.

My Favorite Stuffed Shells Recipe

While I often use a marinara sauce with my stuffed shells, in the spirit of fall, I opted for a luscious, creamy cashew sauce. I also stuffed my shells with roasted butternut squash. This recipe has a few steps, but the creamy, cozy pasta & squash are totally worth the effort. Here’s how you make them:

  1. Roast the squash. Make sure to cut it into little cubes that will fit neatly inside the shells!
  2. Make the cashew cream. Blend together the cashews, water, lemon juice, garlic, salt, and pepper.
  3. Make the “ricotta.” Saute the spinach, squeeze out any excess water, and mix it with crumbled tofu, oregano, lemon zest, red pepper flakes, and 1 cup cashew cream.
  4. Cook the pasta. Don’t forget to salt the water!
  5. Stuff the shells. Fill them with generous scoops of the ricotta and a few cubes of squash.
  6. Bake the stuffed shells! Pop them in the oven for 15 minutes, and you’re ready to eat.

We really love this recipe. I hope you do too!

Butternut Squash Stuffed Shells

This stuffed shells recipe is great for entertaining. Make it as a vegetarian main at Thanksgiving or serve it for the winter holidays!

Ingredients

  • 1½ cups cubed butternut squash
  • extra-virgin olive oil, for drizzling
  • 16 jumbo shells

cashew cream

  • 1½ cups raw cashews*, see note
  • 1 cup fresh water
  • 1 garlic clove
  • 3½ tablespoons fresh lemon juice
  • 1/2 teaspoon sea salt
  • freshly ground pepper

filling

  • 4 cups fresh baby spinach
  • 1 cup crumbled firm tofu
  • 1 teaspoon dried oregano
  • 1/2 teaspoon lemon zest
  • pinch of red pepper flakes
  • 1 cup cashew cream, from the recipe above
  • sea salt and freshly ground pepper

Instructions

  1. Preheat the oven to 350°F and line a baking sheet with parchment paper. Toss the butternut squash with a drizzle of olive oil and a few generous pinches of salt and pepper. Roast until golden brown, 20 to 25 minutes.
  2. Make the cashew cream: Blend together the drained raw cashews, fresh water, garlic, lemon juice, 1/2 teaspoon salt and pepper.
  3. Make the filling: In a medium skillet, heat a drizzle of olive oil over medium heat. Add the spinach in increments, along with a pinch of salt, and sauté until all the spinach is incorporated and wilted. Remove from heat and let cool slightly. Squeeze out any excess liquid and chop. In a medium bowl, combine the the spinach with the crumbled tofu, oregano, lemon zest, red pepper flakes, at least 1/4 teaspoon salt, freshly ground black pepper and 1 cup of cashew cream. Season to taste, adding more salt and pepper as desired.
  4. Bring a large pot of salted water to a boil. Add the shells and cook according to the package directions until al dente. Drain.
  5. Assemble the shells. Spread ¼ cup of the reserved cashew cream on the bottom of an 11x7-inch baking dish. Fill each cooked shell with some of the filling and a few cubes of butternut squash, and place into the baking dish. Drizzle a little olive oil over the shells, cover with foil, and bake for 15 minutes, or until heated through. Remove from the oven and serve with the remaining cashew cream.

Notes

*Depending on your blender, you may want to soak the cashews in water for a few hours (or overnight) in order for them to become creamy when pureed. Drain and rinse when ready to use. If using a Vitamix blender or similar, soaking is not necessary.
