The recipe for this keto cauliflower casserole I’ve written is vegetarian, but we often add crumbled ground beef or cooked, cubed chicken as a layer. Or load it up with other veggies. Mushrooms are a great low carb addition, too. Really, I’ve done so many different things with this basic recipe and it never disappoints. If you're needing a carb-up or carb cycle day, add cooked red lentils to the white sauce (lots of good nutrients in those guys!). Play around with it and enjoy! Let me know if you do something different with it so I can try it too!
