Gluten-Free Mexican Lasagna Bake

Heat the oven to its highest temperature setting, which is 350 degrees Fahrenheit or equivalent in Celsius (175 degrees C).\nSpray a 9x13-inch baking pan with non-stick cooking spray to prevent food from sticking.\nCombine chili, black beans, and onion in a mixing container to create a uniform blend.\nPlace four tortillas flat side down at the bottom of the prepared baking pan; cover with a generous amount of shredded Cheddar cheese. Pour half of the chili mixture over the cheese layer. Repeat this process two more times, finishing with a layer of Cheddar cheese on top. Cover the dish with aluminum foil to prevent overcooking.\nBake in the preheated oven for 20 to 30 minutes, or until the dish is bubbly and hot.
