Ingredients

Instructions

  1. Step 1: Bring a large pot of salted water to a boil. Add 2 cups elbow macaroni and cook for 7-8 minutes until al dente. In the last 3 minutes of cooking, add 1/2 cup frozen peas. Drain and set aside.
  2. Step 2: While pasta cooks, steam 2 cups cauliflower florets until very tender, about 8 minutes. Transfer to a blender or food processor and puree until smooth.
  3. Step 3: In the same pot, 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 cups whole milk and cook, whisking constantly, until thickened and smooth, about 4-5 minutes.
  5. Step 5: Stir in the pureed cauliflower, 2 cups shredded sharp cheddar cheese, 1/2 cup shredded carrots, 1 tsp salt, 1/2 tsp black pepper, and 1/4 tsp garlic powder. Cook for 2 minutes until cheese melts and sauce is creamy.
  6. Step 6: Add the drained macaroni and peas back into the sauce, stirring gently to coat evenly. Cook for 1-2 more minutes until heated through.
  7. Step 7: Serve the vegetable-loaded mac and cheese warm as a comforting, kid-friendly dinner.
