Cheesy Oven-Roasted Cauliflower Au Gratin

Here’s a new way to enjoy that oh-so-healthy cruciferous vegetable! My Cheesy Oven-Roasted Cauliflower Au Gratin is a healthy spin on the traditional potato au gratin, and we all know potatoes can be a big no-no for carb counters. Cauliflower still has carbs, but only about 140 a head versus 150 a potato. And since you only need one head for this whole recipe, carbs are a non-issue.

Cauliflower is one of the most undersung veggies, often overshadowed by its cousin broccoli. But cauliflower has a lot to offer the body with it’s high concentration of vitamin C, variety of B vitamins, folate, sulforaphane and antioxidants.

Let’s face it. Most kids love cheese. And unless your kids are vegetable lovers (every health-driven parent’s dream), it could be hard to sell cauliflower for dinner. But cauliflower baked perfectly with your favorite cheese melted all over — well you have yourself a winner. Pair up this dish with steak or seared lamb for a slam dunk, well-rounded meal!
