  • 2 tsp cooking oil (avocado or olive oil)
  • 1 small butternut squash, peeled, seeded, and cut into 1-inch chunks (about 4 cups)
  • 8 oz. elbow macaroni (2 cups dried pasta)
  • 1 small yellow onion, chopped (about 1 cup)
  • 2 cloves garlic, minced
  • 1/2 tsp ground mustard
  • 1/2 tsp salt, more to taste
  • 1.5 cups shredded sharp cheddar cheese
  • 2.5 cups unsweetened almond milk


Roast the Butternut Squash

  • Preheat the oven to 400 degrees Fahrenheit. 
  • In a large bowl, toss the butternut squash chunks with 1 tsp of oil until all pieces are coated. Season with salt and pepper.
  • Spread the squash pieces evenly on a baking sheet and bake for 25 minutes until the pieces are tender. 
  • While the squash is roasting, cook the pasta according to package directions.

Make the Sauce

  • Heat 1 tsp of oil in a heavy-bottomed pot (like a Dutch oven) over medium-high heat. Add the onion and cook for 5 minutes until it starts to become translucent. Add the garlic, mustard powder, salt, and cook another 30 seconds. 
  • Turn the heat off and add 4 cups of roasted squash chunks to the pot with the onions. Then use an immersion blender to puree everything together. I use an immersion blender to minimize cleanup, but you can also puree everything in a food processor or high-speed blender and then transfer it back to the pot.
  • Turn the heat to low and add the cheese and almond milk. Stir slowly until the cheese melts and the mixture becomes smooth. 
  • Add the drained pasta to the sauce and stir to combine. If you want the sauce to have a thinner consistency, slowly add more almond milk until it reaches the desired consistency.
