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: Steam 1 cup cauliflower florets and 1 cup fresh spinach leaves together over boiling water for 6 minutes until very tender.
  3. Step 3: Transfer steamed cauliflower and spinach to a blender or food processor and puree until very smooth, about 1 minute. Set aside.
  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, stirring constantly until golden and bubbling but not browned.
  5. Step 5: Gradually whisk in 2 cups whole milk, continuing to whisk until the sauce is smooth and starts to thicken, about 5 minutes.
  6. Step 6: Lower heat to low and stir in the cauliflower-spinach puree, 2 cups shredded sharp cheddar cheese, 2 oz cream cheese, 1/2 tsp garlic powder, 1 tsp salt, 1/4 tsp black pepper, and 1/4 tsp paprika. Cook, stirring, until cheese melts and sauce is creamy.
  7. Step 7: Add the drained macaroni to the cheese sauce and stir until all pasta is evenly coated.
  8. Step 8: Transfer macaroni and cheese to a buttered 8x8-inch baking dish. Sprinkle 1/2 cup bread crumbs evenly on top.
  9. Step 9: Broil in the oven on high for 3-4 minutes until bread crumbs are golden and crisp. Watch carefully to prevent burning. Let cool for 5 minutes before serving.
