Ingredients
  • 1 pound ground beef
  • 1 large egg, room temperature
  • 1 tablespoon + ½ teaspoon fajita seasoning, divided
  • Pinch of chili flakes
  • ⅓ teaspoon onion powder
  • ¾ teaspoon garlic powder, divided
  • salt, to taste
  • pepper, to taste
  • ½ cup mayonnaise
  • ¼ cup sour cream
  • 1 tablespoon fresh coriander, finely chopped
  • Juice of ½ lime
  • 1 tablespoon cooking oil
  • 1 large onion, sliced
  • 2 red bell peppers, sliced
  • 6 slices cheddar cheese
  • 6 burger buns
  • 1 cup lettuce leaves
Directions
  1. In a large bowl, combine the ground beef, egg, 1 tablespoon of fajita seasoning, chili flakes, onion powder, ½ teaspoon of garlic powder, salt, and pepper.
  2. Form the beef patties into round shapes, making 6 in total, with dimples in the middle. Chill the beef patties in the fridge for at least 30 minutes.
  3. To make the sauce, mix together the mayonnaise and sour cream with ¼ teaspoon of garlic powder, the chopped fresh coriander, the lime juice, and ½ teaspoon of fajita seasoning.
  4. Heat up the cooking oil in a large pan to a medium heat.
  5. Add the sliced onion and bell peppers, and saute for 15 minutes or until caramelized. Set aside.
  6. Heat up a lightly greased cast iron pan to a medium-high heat, then add the beef patties, as many as will reasonably fit. Don't overcrowd the pan.
  7. Cook for 3-4 minutes each side until the patties are browned on the outside and just cooked through.
  8. Top the burgers with sliced cheddar cheese and allow it to melt about 1-2 minutes before the burgers are done cooking.
  9. Serve the buns by layering a spoonful of sauce followed by lettuce, the cooked beef patty, a spoonful or two of the cooked onions and peppers, and the top of the burger bun, similarly slathered with a spoonful of sauce.
