Ingredients

quick fire roasted marinara

  • 2 14-ounce cans fire-roasted diced tomatoes
  • 2 tablespoons tomato paste
  • 2 garlic cloves minced
  • 2 tablespoons unsalted butter
  • 2 tablespoons chopped fresh basil

stuffed shells

  • 2 tablespoons unsalted butter
  • 1 sweet onion sliced
  • 1/2 cup butternut squash cubes 1/2-1 inch cubes
  • 12 ounce mushrooms chopped
  • 8 ounces fresh spinach chopped (I just run my knife through it once or twice)
  • 3 garlic cloves minced
  • 1 1/2 cups whole milk-ricotta cheese
  • 8 ounces fontina cheese freshly grated
  • 1 large egg lightly beaten
  • 1/4 teaspoon salt
  • 1/4 teaspoon pepper
  • 12 ounces jumbo pasta shells cooked according to directions
  • fresh basil and oregano to garnish

Instructions 

quick fire roasted marinara

  • Add the tomatoes, paste, garlic and butter together in a saucepan and heat over medium-low heat. Stir to combine, then cover and cook for 30 to 40 minutes, stirring occasionally, until the diced tomatoes have broken down. Stir in the basil.

stuffed shells

  • Preheat the oven to 350 degrees F. Spray a baking dish (I used a 9x9 but you can also do a 9x13, this should make enough shells and filling) with nonstick spray.
  • Heat a large skillet over low heat and melt the butter. Once melted, stir in the onions, squash and a pinch of salt and cook, stirring often, until the onions are caramely and golden, about 25 to 30 minutes. Add in the mushrooms and cook until they are soft and juice, about 6 minutes. Stir in the spinach and garlic, cooking until the spinach wilts.
  • In a bowl, stir together the ricotta and almost all of the fontina, reserving some for the top. Stir in the beaten egg. Add in the salt and pepper. Fold in the cooked vegetables until combined.
  • Spoon 1/2 cup of marinara in the bottom of the baking dish. Take the cooked pasta shells and fill them with the cheesy vegetable mixture and place them in the baking dish. Cover them with all of the marinara and the remaining fontina cheese. Bake for 30 to 35 minutes, until golden and bubbly.
  • Top with fresh oregano and basil to serve.
