18 steps

Prepare the grill for direct cooking at about 450°F.
Place a plancha or Weber Works griddle on the right side of the grill and allow it to preheat.
In a mixing bowl, combine the olive oil, melted butter, and French onion dip seasoning for the onions. Add the sliced onions and toss to coat. Season lightly with salt and pepper.
In a separate bowl, toss the quartered potatoes with the olive oil, salt, and pepper.
Season both sides of the hamburger patties generously with French onion dip seasoning.
Spread the softened butter on the cut sides of the brioche buns.
Bring the prepared ingredients to the grill.
Brush the preheated grill grates clean.
Add the onions to one area of the preheated plancha or griddle, leaving room for the potatoes. Cook for 20–25 minutes, stirring occasionally, until caramelized.
Add the potatoes to the open area of the plancha or griddle. Cook for 10–15 minutes, stirring occasionally, until tender.
Grill the hamburger patties over direct medium-high heat, about 450–500°F, with the lid closed as much as possible. Cook for 5 minutes.
Flip the patties and cook for another 4 minutes.
Use a thermometer to check the burgers for doneness.
Top each burger with one slice of Gruyère and one slice of Swiss cheese. Place the buns cut side down over direct heat.
Cook for about 1 minute, until the cheese melts and the buns are toasted.
Place a cheeseburger on each bottom bun.
Top with caramelized onions and the top bun.
Serve warm with the grilled baby red potatoes.
