Cheesy Cauliflower Gratin

This easy recipe makes a great side dish for any main. Tender steamed cauliflower is baked with cheese, cream cheese, mayonnaise, and spices.

This cauliflower casserole is one of my go-to recipes. It’s great for potlucks, holiday dinners, weeknight dinners, and more! Furthermore, it’s lower in carbs than most casseroles and gluten-free.

You can add more vegetables by stirring in steamed broccoli or carrots. As well, you can add bacon.

If you arent’ looking for Keto-friendly, try topping this casserole with crushed butter crackers or potato chips. You can also top it with more cheese. Because there’s no such thing as too much cheese!
