To make this Chicken Taco Lasagna gluten free, use certified gluten-free oven-ready lasagna noodles or substitute gluten-free tortillas for a casserole-style version. Also confirm that the taco seasoning, salsa, baking spray, and any toppings are labeled gluten free, since packaged products can sometimes contain hidden gluten. If serving someone with celiac disease or severe gluten sensitivity, be careful to avoid cross-contact by using clean utensils, cookware, and preparation surfaces.
