Instructions

• Preheat oven to 350°F. Spray a 2.5- to 3-quart baking dish with cooking spray and set aside.
• In a large skillet over medium-high heat, add 1 pound ground beef and ½ medium onion (diced). Cook, breaking up the meat, until the beef is browned and the onion is softened, about 6–8 minutes. If necessary, drain excess fat and return the skillet to the heat.
• Stir in 4 ounces diced green chiles, 14.5 ounces diced tomatoes (undrained), and the taco seasoning (11.25-ounce package taco seasoning mix OR 4 tablespoons homemade taco seasoning). Reduce heat to medium and simmer, stirring occasionally, 3–5 minutes, until heated through.
• Remove the skillet from the heat. Stir in 16 ounces refried beans and 1 cup sour cream until the mixture is well combined and smooth.
• Crush 10 ounces tortilla chips and divide them into two equal portions. Place half of the crushed chips in an even layer on the bottom of the prepared baking dish.
• Spoon the beef-and-bean mixture over the layer of chips and spread evenly. Sprinkle 1 cup shredded Mexican-style cheese blend evenly over the mixture, then scatter the remaining crushed tortilla chips on top.
• Bake in the preheated oven for 15–20 minutes, or until the cheese is fully melted and the casserole is heated through.
• Remove from the oven and let rest 5 minutes. Serve with the remaining optional toppings as desired: Sour cream, Diced fresh tomatoes, Salsa, Guacamole or sliced avocado, Fresh cilantro, and Pickled jalapeños.
