Ingredients:

  • 1/2 lb (225g) ground beef (80/20 blend)
  • 1 tbsp (15ml) olive oil
  • 1/4 tsp (1.5g) garlic powder
  • 1/4 tsp (1.5g) onion powder
  • 1/2 tsp (3g) salt
  • 1/4 tsp (1.2g) black pepper
  • 1 tsp (5ml) Worcestershire sauce
  • 4 slices (120g) sourdough bread
  • 4 slices (80g) sharp cheddar cheese
  • 2 tbsp (28g) unsalted butter, softened
  • 1 tbsp (15g) mayonnaise

Instructions:

  1. Heat olive oil in a 12 inch skillet over medium high heat until shimmering. Note: This ensures the beef sears instead of steaming
  2. Add the ground beef to the skillet, breaking it into small crumbles with a spatula.
  3. Season the beef with garlic powder, onion powder, salt, and black pepper. Cook until browned and edges are slightly crisp.
  4. Stir in the Worcestershire sauce, cook for 1 additional minute, then remove the beef from the pan and set aside on a plate.
  5. Wipe the skillet clean. Note: Removing the loose beef bits prevents the bread from burning unevenly
  6. Spread a thin layer of softened butter on one side of each sourdough slice and a thin layer of mayonnaise on the non buttered side.
  7. Place two slices of bread butter side down in the skillet.
  8. Immediately top each slice with a slice of cheddar cheese, a generous scoop of the seasoned beef mixture, and another slice of cheese.
  9. Top with the remaining bread slices, butter side up.
  10. Cook over medium heat for 3–4 minutes per side, applying light pressure with a spatula, until the bread is mahogany colored and the cheese is melted.
