Cheesy Beef Nacho Casserole

Instructions

1. Step
   Preheat Oven: Preheat your oven to 375°F (190°C).
2. Step
   Cook the Beef: In a large skillet, melt the butter over medium heat. Add the ground beef and cook until browned, breaking it apart with a spoon as it cooks. Drain any excess fat.
3. Step
   Add Onion and Seasoning: Add the diced yellow onion to the skillet with the beef and cook for 2-3 minutes, until the onion is softened. Stir in the taco seasoning and cook for another minute, allowing the spices to bloom.
4. Step
   Combine the Tomatoes and Beans: Add the fire-roasted tomatoes (with their juices) and kidney beans to the skillet. Stir to combine, then let the mixture simmer for about 5 minutes, allowing the flavors to meld together.
5. Step
   Assemble the Casserole: In a large baking dish, layer half of the crushed Doritos chips. Top with half of the beef mixture, followed by half of the sour cream and half of the shredded cheddar cheese. Repeat with another layer of chips, beef mixture, sour cream, and cheese.
6. Step
   Bake the Casserole: Bake in the preheated oven for 15-20 minutes, or until the cheese is melted and bubbly.
7. Step
   Garnish and Serve: Remove the casserole from the oven and let it cool slightly. If desired, garnish with sliced jalapeños for an extra kick. Serve hot and enjoy!
