Tips for the Best Keto Cauliflower Au Gratin
- Choose the Right Cheese: Gruyere brings a rich, nutty flavor, but Swiss or even cheddar can work well for a different twist.
- Don’t Overcook the Cauliflower: The goal is tender, not mushy, so keep an eye on it during the baking time.
- Let It Rest: Giving the casserole a few minutes to rest after baking allows the creamy sauce to thicken, making it easier to serve.
