• 1 can (15 oz / 425g) Ranch Style beans
• 1 packet taco seasoning
• 1 can (10.5 oz / 298g) cream of chicken soup

👩‍🍳 Instructions

1. Prepare the Filling:
   Preheat your oven to 325°F (163°C).
   In a large skillet over medium heat, cook the ground beef and chopped onion until browned and fully cooked. Drain any excess fat.
   Stir in the Ro-Tel tomatoes, Ranch Style beans, taco seasoning, cream of chicken soup, and water. Let the mixture simmer for 5–7 minutes, until well combined and heated through.
2. Assemble the Casserole:
   Lightly grease a 9×13-inch (23×33 cm) casserole dish.
   Spread a layer of crushed tortilla chips across the bottom.
   Spoon half of the meat mixture over the chips.
   Sprinkle with 1 cup of shredded cheddar cheese.
   Repeat with another layer of chips, remaining meat mixture, and finish with the remaining cheese on top.
3. Bake and Serve:
   Cover the dish with foil and bake for 20–30 minutes, until hot and bubbly.
   Remove from the oven and let the casserole rest for 5–10 minutes before serving.
   Serve warm with a dollop of sour cream and a spoonful of salsa for extra flavor.
