  • 9 x 13 Baking Dish
  • Mixing Bowls
  • Large Saucepan or Stockpot
  • Large Skillet


For Pasta:

  • 1 ½ lbs Sweet Potatoes, roasted until tender (about 2 large) (see note)
  • 12 oz Fusilli Pasta
  • 1 Tbsp Extra Virgin Olive Oil
  • 1 Onion, finely diced
  • 2 large Carrots, finely diced
  • 1 ½ cups Low Sodium Vegetable Broth
  • ¼ cup plain Greek Yogurt
  • 4 oz Sharp Cheddar Cheese, shredded

For Topping:

  • 2 oz Parmesan Cheese, finely grated
  • 10 leaves Fresh Sage
  • Extra Virgin Olive Oil


  • Lightly grease a 9x13 baking dish. Preheat the oven to 350 degrees F.
  • Scoop the cooked sweet potato into a bowl and lightly mash with a fork until nearly smooth.
  • Boil noodles according to package instructions, but stop cooking them 2-3 minutes sooner than directed. (The noodles will finish in the sauce, so don't overcook them!)
  • Heat the olive oil in a large skillet over medium-high heat. When the oil is shimmering, add the onions and carrots and sauté until very tender, about 6-8 minutes. Add the vegetable broth and mashed sweet potato and stir gently until it begins to simmer. Remove the skillet from the heat. In a large bowl, combine the cooked pasta, sweet potato sauce, Greek yogurt, and cheddar cheese. Stir to mix well. Pour the pasta into the prepared baking dish.
  • Top the pasta with parmesan cheese. Dip each of the fresh sage leaves in olive oil and scatter them over the cheese. Bake until evenly heated through, 15-17 minutes. Turn on the oven's broiler and broil until the parmesan is golden and the sage leaves are crisp, about 2-3 minutes. Serve immediately.


I like to roast my sweet potatoes for this recipe by wrapping them in foil, piercing them with a knife, and putting them in a 400 degree oven until very tender, about 45 minutes. Alternatively, you can microwave them on high (pierce them with a knife, but DON'T wrap them in foil), until tender all the way to the center, 7 to 10 minutes.
