The beauty of this casserole lies in its flexibility. To personalize your creation, swap bell peppers with diced zucchini or mushrooms for an earthier tone. Adding cooked, diced turkey bacon or shredded chicken boosts protein without overpowering the cauliflower’s delicate flavor. Want a creamier consistency? Stir in 1/4 cup of full-fat coconut milk or heavy cream with your eggs for extra richness.

You can also freeze individual slices for up to 3 months - just thaw overnight in the fridge before reheating.
