Hatch Chile Relleno Casserole with Ranchero Sauce

Preheat the oven to 350 degrees F (175 degrees C). Coat a 9x13-inch baking dish with cooking spray.

Place egg whites in a bowl and beat until stiff. Gently fold in evaporated milk flour and salt. Cover bottom of baking dish with 1/2 the egg white mixture. Place chiles flat over egg whites. Sprinkle Oaxaca cheese over chiles. Top with remaining chiles and egg white mixture.

Bake in the preheated oven until eggs are set about 30 minutes.

While casserole bakes heat oil in a medium saucepan over medium-high heat. Saute onion and garlic for 2 minutes. Add chile powder salt and cumin. Cook and stir for another minute. Add bell peppers and cook until soft 3 to 5 minutes. Add flour and stir for 2 minutes. Slowly add broth stirring to avoid lumps. Bring to a boil; reduce heat to low and simmer until casserole is ready.

Serve the sauce with slices of the chile relleno casserole.
