Ingredients

Instructions

  1. Step 1: Bring a large pot of salted water to a boil. Add 10 oz elbow macaroni and cook for 7-8 minutes until al dente. Drain and set aside.
  2. Step 2: In a medium pot, steam 2 cups cauliflower florets and 1 medium peeled cubed sweet potato until very tender, about 10 minutes. Transfer to a blender and puree until smooth; set aside.
  3. Step 3: In a large saucepan, melt 3 tbsp unsalted butter over medium heat. Whisk in 3 tbsp all-purpose flour and cook for 1 minute until bubbling but not browned.
  4. Step 4: Gradually whisk in 2 1/2 cups whole milk and continue whisking until the sauce thickens and coats the back of a spoon, about 5-6 minutes.
  5. Step 5: Remove sauce from heat and stir in 2 cups shredded sharp cheddar cheese, 2 oz cream cheese, 1 tsp Dijon mustard, 1/2 tsp garlic powder, 1 tsp salt, and 1/4 tsp black pepper until smooth.
  6. Step 6: Fold in the pureed cauliflower and sweet potato mixture along with the cooked macaroni, stirring to combine evenly.
  7. Step 7: Preheat oven to 375°F. Transfer mac and cheese to a greased 9x9 inch baking dish.
  8. Step 8: Toss 1/2 cup panko breadcrumbs with 1 tbsp olive oil and sprinkle evenly over the top. Bake for 20 minutes until the topping is golden and crispy.
  9. Step 9: Let rest for 5 minutes before serving to thicken up the sauce.
