This Broccoli Cheddar Mac & Cheese is the ultimate cozy fall comfort food. Tender pasta and crisp-tender broccoli are coated in a silky, cheddar-loaded béchamel sauce enriched with garlic and mozzarella. The sharpness of the cheddar is balanced by creamy mozzarella, and a touch of mustard powder adds subtle warmth and complexity. Optionally, you can bake it to perfection for a golden top. Whether served as a main dish or a side, it’s a crowd-pleaser you’ll crave again and again.
