Ingredients

Instructions

  1. Step 1: Preheat oven to 350°F. Bring a large pot of salted water to a boil. Add 8 oz elbow macaroni and cook for 7 minutes until al dente, then drain and set aside.
  2. Step 2: Steam 1 cup chopped cauliflower florets and 1 cup peeled cubed butternut squash in a steamer basket over boiling water for 10 minutes until very tender.
  3. Step 3: Transfer steamed vegetables to a blender and blend until smooth, adding 1/4 cup milk to loosen if necessary.
  4. Step 4: In a large saucepan, melt 3 tbsp unsalted butter over medium heat. Whisk in 3 tbsp all-purpose flour and cook for 1-2 minutes until the mixture bubbles but does not brown.
  5. Step 5: Gradually whisk in 2 1/2 cups whole milk, stirring constantly until the sauce thickens and coats the back of a spoon, about 5 minutes.
  6. Step 6: Stir in the pureed cauliflower and butternut squash, then add 2 cups shredded sharp cheddar cheese and 1 cup shredded mozzarella cheese. Cook gently until cheeses melt and sauce is smooth.
  7. Step 7: Season with 1 tsp salt, 1/2 tsp black pepper, 1/4 tsp smoked paprika, and 1/4 tsp garlic powder.
  8. Step 8: Combine the cheese sauce with the drained macaroni, stirring thoroughly to coat.
  9. Step 9: Transfer the mixture to a greased 9x9-inch baking dish and bake uncovered for 20 minutes until bubbly with lightly browned edges.
