Ingredients

The following ingredients have 4 Servings
  • 2 tablespoon unsalted butter (browned)
  • 1 medium sweet potato (cubed into 2-inch cubes)
  • 2 tablespoon all-purpose flour
  • 1 cup whole milk
  • 1 3/4 cup water (divided)
  • 1 cup freshly grated Parmesan cheese
  • 1 pound dried spaghetti pasta (cooked according to the directions on the box)
  • 1/4 teaspoon cayenne pepper (more or less depending on heat preference)
  • Salt and pepper (to taste)

Instruction

  • Bring a pot of water to a boil and add the cubed sweet potatoes and cook until fork tender. Carefully place sweet potatoes into a blender and puree until smooth.
  • In a large pot over medium heat, add the brown butter and whisk together with flour for 30 seconds. Turn the heat up to medium-high and carefully add the milk and continue whisking until mixture thickens, about 3-4 minutes. At this time, add the pureed sweet potatoes and 1 1/2 cup of water. Let the mixture simmer for 5-7 minutes until thickened then add the Parmesan cheese, cayenne, salt, pepper, and turn off the heat. If the mixture seems too thick, you can add the remaining 1/4 cup of water to thin it out.
  • Add the cooked pasta to the pot and toss until well-coated.
