Instructions

Step 1: Prepare the Oven and Pan
Set the oven to 350°F (175°C). Line a baking sheet with parchment paper or lightly grease it.

Step 2: Brown the Beef
In a large skillet over medium heat, cook the ground beef with the diced onion until fully browned. Season with salt and pepper, then drain off any excess fat.

Step 3: Shape the Dough
Lightly flour a work surface and roll the French bread dough into a rectangle approximately 12×18 inches.

Step 4: Spread the Sauces
Evenly spread the ketchup and mustard over the dough, leaving about a ½-inch border along the edges.

Step 5: Add the Fillings
Distribute the cooked beef, crumbled bacon, and chopped pickles evenly over the sauced dough.

Step 6: Layer the Cheese
Place the American cheese slices on top of the fillings in an even layer.

Step 7: Roll and Seal
Starting from one long edge, roll the dough tightly into a log. Pinch the seams closed and place it seam-side down on the prepared baking sheet.

Step 8: Finish and Bake
Brush the top of the dough with the beaten egg and sprinkle with sesame seeds. Bake for 20–25 minutes, or until the bread is golden brown.

Step 9: Rest and Serve
Allow the bread to cool for at least 5 minutes before slicing. Serve warm with Thousand Island dressing on the side for dipping.
