Easy Cheeseburger Tacos

Preheat the oven to 375 degrees F (190 degrees C). Lightly grease a 9x13-inch baking dish.

Heat a large skillet over medium-high heat. Add beef; season with garlic powder, black pepper, and salt. Cook and stir until meat is browned and crumbly, 5 to 7 minutes; drain and discard grease. Reduce heat to low. Stir 1/2 cup ketchup into beef.

Lay 1 tortilla onto a work surface; place about 1/3 cup beef mixture and 1/4 cup shredded cheese onto tortilla in a line across the middle. Roll tortilla over filling, fold in top and bottom to enclose filling, and finish rolling into a burrito shape. Place filled tortilla into the prepared baking dish. Repeat with remaining tortillas and filling. Sprinkle remaining Mexican cheese blend on tacos. Cover dish with aluminum foil.

Bake in the preheated oven until tacos are heated through and cheese topping has melted, 20 to 25 minutes. Combine sour cream and 1/3 cup ketchup in a bowl. Top each taco with sauce.
