Step 1

Preheat oven to 400°F.

Step 2

Form ground beef into 2 patties slightly wider than the buns. Press the center of each patty to make a slight indentation with your fingertips. Season liberally with salt and pepper on all sides. Set aside.

Step 3

Line a rimmed baking sheet with aluminum foil. Place the bacon slices on the baking sheet and bake until bacon is crisp for about 15 minutes, rotating once.

Step 4

When bacon is cooked, remove from oven and transfer to a paper towel-lined plate. Reserve.

Step 5

Preheat a cast iron over medium-high heat. When hot, add a little vegetable oil and cook the burger patties, turning occasionally, until well-crusted and almost cooked through (120F), about 3 minutes per side. Top with the cheese and continue cooking until the cheese melts and burger registers 125°F for medium rare or 135°F for medium. Transfer to a plate and reserve.

Step 6

Start assembling your burger by spreading mayonnaise on both sides of the bun. Then, add the lettuce leaves, tomato, corn, burger patty cheese cheese, second burger patty with cheese, bacon and fries. Before closing the burger with the top bun, don't forget the fried egg!

Step 7

In a small nonstick pan over medium heat, add a thin film of olive oil, and crack an egg into the pan. Fry the egg, undisturbed, until cooked to your liking, about 2 to 3 minutes for a slightly runny yolk.

Step 8

Top the burger with the egg, ketchup and mustard (if using) and the top bun.

Step 9

Serve immediately!
