Ingredients

For roasted butternut squash

  • 16 ounces butternut squash cubed, about 2 cups
  • 2 tablespoons olive oil
  • ½ teaspoon kosher salt
  • ¼ teaspoon black pepper

For the mac 'n' cheese

  • 12 ounces elbow macaroni gluten-free or regular
  • 2 tablespoons butter or ghee
  • 1 medium onion diced
  • 1 shallot diced
  • 3 cloves garlic minced
  • 2 tablespoons flour all-purpose or gluten-free
  • 1 tablespoon dried mustard
  • teaspoons dried sage
  • 2 cups dairy-free milk almond or cashew work well
  • ½ cup vegetable stock
  • 8 ounces sharp white cheddar shredded
  • ½ teaspoon kosher salt
  • ½ teaspoon black pepper

Instructions

For roasted butternut squash

  • Preheat oven to 400 degrees F.
  • Toss cubed butternut squash with olive oil, salt and pepper. Transfer to parchment-lined baking sheet.
  • Roasted for about 35 to 40 minutes, flipping halfway through. Set aside.

For the mac 'n' cheese

  • Reduce oven to 375 degrees F. Cook macaroni according to package directions, drain and set aside.
  • In a large pot, cook macaroni according to package directions. Drain and set aside.
  • While macaroni is cooking, add roasted squash and ½ cup vegetable stock to a blender. Blend until smooth.
  • In the same large pot used to cook the macaroni, melt 2 tablespoons butter or ghee over medium-high heat. Once melted, add diced onion and shallot. Cook for about 5 to 7 minutes, until onion is translucent.
  • Add garlic and cook for 1 to 2 minutes. Reduce heat to medium and add in 2 tablespoons flour and 1 tablespoon dried mustard. Stir continuously for about 3 minutes, careful not to burn.
  • Reduce heat to low. Add in 2 cups alternative milk. Stir continuously until the consistency of gravy is reached. Season with dried sage, ½ teaspoon salt and ¼ teaspoon black pepper.
  • Remove from heat and stir in butternut squash puree and about ⅔ of the shredded cheese, reserving the rest.
  • Return cooked pasta to the pan and stir until well combined. Taste and adjust seasoning, as needed.
  • Pour into a 2-quart baking dish and sprinkle remaining shredded white cheddar on top. Bake for about 25 minutes, or until cheese is melted and bubbly.
  • Serve.

Notes

If you prefer, you can roast a whole butternut squash and measure out the 2 cups of squash for the puree. To roast a whole squash:
  • Preheat oven to 400 degrees F.
  • Cut squash in half lengthwise. Scoop out the seeds and score the cut-side of the squash.
  • Brush the cut-side with olive oil and season with salt and pepper.
  • Place cut-side down on a parchment-lined baking sheet.
  • Bake on the middle rack for 45 to 55 minutes, until squash is easily pierced with a fork.
Squash can be roasted, scooped out and stored in an air-tight container up to 4 days in advance.
