French Bistro Brisket Burger with Gruyère & Frites

Instructions

1. 1

   Peel and cut the russet potatoes into thin fries. Soak them in cold water for 30 minutes, then drain and pat dry thoroughly.

2. 2

   Heat the sunflower oil in a deep fryer or large pot to 160°C (320°F). Fry the potatoes in batches for 4-5 minutes until soft but not colored. Remove and drain on paper towels.

3. 3

   Increase the oil temperature to 190°C (375°F). Fry the potatoes again in batches for 2-3 minutes until golden and crispy. Drain and sprinkle with sea salt. Set aside and keep warm.

4. 4

   Divide the ground brisket beef into 4 equal portions and shape into burger patties. Season both sides with salt and pepper.

5. 5

   Heat a grill or skillet over medium-high heat. Cook the patties for 3-4 minutes per side for medium, or until desired doneness.

6. 6

   In the last minute of cooking, place a slice of Gruyère cheese on each patty and cover to melt the cheese.

7. 7

   Lightly toast the brioche buns. Spread 1 tbsp of Dijon mustard on the bottom half of each bun.

8. 8

   Place a butter lettuce leaf on each bun, then top with the cheesy brisket patty, 1 tbsp caramelized onions, and the top bun.

9. 9

   Serve the burgers immediately with the hot, crispy frites on the side.
