  • 2 cloves garlic, minced
  • 1 teaspoon chili powder
  • 1 teaspoon ground cumin
  • 1/2 teaspoon paprika
  • 1/2 teaspoon dried oregano
  • Salt and black pepper, to taste
  • 1 (15-ounce) can diced tomatoes, drained
  • 1 cup shredded cheddar cheese
  • Optional toppings: chopped green onions, sliced jalapenos, diced tomatoes, sour cream, salsa



  1. Preheat your oven to 350°F (175°C). Grease a 9×13-inch baking dish with cooking spray or butter.
  2. In a large skillet, cook the ground beef or turkey over medium heat until browned and cooked through, breaking it apart with a spoon as it cooks.
  3. Add the chopped onion and minced garlic to the skillet with the cooked meat. Cook for an additional 2-3 minutes, until the onion is softened and translucent.
  4. Stir in the chili powder, ground cumin, paprika, dried oregano, salt, and black pepper. Cook for another minute to toast the spices and allow the flavors to meld together.
  5. Add the drained diced tomatoes to the skillet and stir to combine. Cook for another 2-3 minutes, until heated through. Remove the skillet from the heat.
  6. Arrange the split hot dog buns in the prepared baking dish, cut side up, creating a single layer.
  7. Spoon the seasoned meat mixture evenly over the hot dog buns in the baking dish, spreading it out to cover the buns.
  8. Sprinkle the shredded cheddar cheese evenly over the top of the meat mixture.
  9. Cover the baking dish with aluminum foil and bake in the preheated oven for 20-25 minutes, until the cheese is melted and bubbly.
  10. Remove the foil from the baking dish and switch the oven to broil. Broil the casserole for an additional 2-3 minutes, until the cheese is golden brown and bubbly.
  11. Remove the casserole from the oven and let it cool slightly before serving.
  12. Serve the Hot Dog Bun Casserole hot, garnished with optional toppings such as chopped green onions, sliced jalapenos, diced tomatoes, sour cream, and salsa.
