With just 4 grams of fat per serving, it’s a low-fat, low-calorie, and fiber-rich way to enjoy cheesy comfort food.

About This Recipe
The creamy texture, tender-crisp broccoli, and bubbly cheese topping make each bite comforting and satisfying. It’s got the rich flavor you expect from a cheese casserole but feels light and clean, not greasy or heavy.
This dish is ideal for weeknight dinners, holiday meals, or meal prepping for the week. It pairs well with grilled chicken or turkey and can also stand alone as a light vegetarian entrée.
Why This Recipe Belongs in Your Diet
Broccoli is packed with fiber, vitamin C, and folate, making it a nutritional powerhouse. Instead of cream or butter, fat-free Greek yogurt and a little part-skim cheese provide the creaminess and flavor you love while keeping saturated fat low. Baking brings everything together without needing excess oil or butter.
