Cauliflower Alfredo Casserole is creamy, cheesy, and very comforting. It tastes rich like classic Alfredo but feels lighter because cauliflower replaces most of the pasta. This dish is perfect for a cozy dinner, a low-carb option, or a side dish everyone will love. The baked top becomes golden and slightly crispy while the inside stays soft and creamy.
