Burger Patty

Bun and Cheese

Caramelized Onions

Harissa Aioli

French Fries

Method

Preparing the Burger Patty

  1. 1

    Mix and Shape the Patty

    In a bowl, combine the ground beef with salt and black pepper. Mix until just combined. Form into a patty about 1/2 inch thick.

  2. 2

    Cook the Patty

    Heat a grill or skillet over medium-high heat. Cook the patty for about 4-5 minutes on each side or until desired doneness.

Bun and Cheese Assembly

  1. 3

    Toast the Brioche Bun

    Slice the brioche bun in half and toast it lightly on the grill or in a toaster.

  2. 4

    Add Cheese

    Place a slice of smoked cheddar cheese on the patty during the last minute of cooking to melt.

Caramelizing the Onions

  1. 5

    Cook the Onions

    Slice the onion thinly. In a skillet, heat olive oil over medium heat. Add the sliced onions and salt, cooking slowly for about 15-20 minutes until golden and caramelized.

Making Harissa Aioli

  1. 6

    Mix the Aioli

    In a bowl, combine mayonnaise, harissa paste, minced garlic, and lemon juice. Mix well until smooth. Adjust seasoning if necessary.

Preparing French Fries

  1. 7

    Cut the Potatoes

    Peel and cut the potatoes into fries. You can make them as thick or thin as you like.

  2. 8

    Fry the Potatoes

    Heat oil in a deep fryer or pot to 350°F (175°C). Fry the potatoes in batches until golden brown, about 5-7 minutes. Remove and drain on paper towels, sprinkling with salt to taste.

Assembling the Burger

  1. 9

    Assemble the Burger

    On the bottom half of the toasted brioche bun, spread a generous amount of harissa aioli. Place the burger patty with melted cheese on top, followed by caramelized onions. Top with the other half of the bun and serve with French fries.
