Cheesy Cauliflower Gratin
Helpful Tips for Making Cauliflower Gratin Casserole
Cauliflower is often overlooked as a delicious side dish, but it's so incredibly versatile and readily available at the market. I have many cauliflower recipes to try and add to your dinner menu.
- I typically use fresh cauliflower for this dish but you can certainly adapt using frozen steamed cauliflower in the same amount to lessen prep time.
- When making the cheese sauce, don't walk away, it needs to be stirred constantly to prevent sticking.
- The cheese I use is an Italian blend of mozzarella and provolone. You can use any cheese you like in this recipe.
- More cauliflower recipes to try from the recipe index creamy Mashed Cauliflower, Oven Roasted Panko Parmesan Cauliflower and Cheddar Cauliflower Soup with Bacon will warm you up on a chilly day.
