Can I make cheesy baked fajita chicken ahead of time?

Yes, absolutely! You can assemble the dish up to 24 hours ahead and store it covered in the refrigerator. Bake it just before serving to enjoy the melty, gooey cheese and fresh roasted veggies. It’s also great for meal prep — baked portions keep well in the fridge for up to 3 days.

Is this recipe suitable for a low-carb or keto diet?

Yes, cheesy baked fajita chicken is naturally low in carbs and fits well into keto and low-carb diets , especially if served without tortillas or rice. You can further reduce the carbs by cutting back on onions and pairing it with low-carb sides like cauliflower rice or sautéed greens.
