Burger Ingredients

Chef Tony's Sauce

Sweet Potato Fries

Method

Prepare the Sweet Potato Fries

  1. 1

    Preheat and Cut

    Preheat the oven to 425°F (220°C). Peel and cut the sweet potatoes into thin fries.

  2. 2

    Season and Bake

    In a bowl, toss the sweet potato fries with olive oil, salt, pepper, and paprika. Spread them out in a single layer on a baking sheet and bake for 25-30 minutes, flipping halfway through until crisp and golden.

Prepare the Burger

  1. 3

    Cook the Bacon

    In a skillet over medium heat, cook the bacon until crispy. Remove and place on paper towels to drain excess grease.

  2. 4

    Caramelize the Onion

    In the same skillet, add sliced onion and cook over medium-low heat until caramelized, about 15 minutes. Stir occasionally to avoid burning.

  3. 5

    Form and Cook the Patties

    In a bowl, season the ground beef with salt and pepper. Form into two patties. In the same skillet, cook the patties over medium-high heat for about 4-5 minutes on each side, or until they reach your desired doneness.

  4. 6

    Add Cheese

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

  5. 7

    Fry the Eggs

    In a separate pan, heat a little butter and fry the eggs sunny-side up or over easy, as preferred.

  6. 8

    Toast the Buns

    Spread butter on the brioche buns and toast them in the skillet until golden brown.

Assemble the Burger

  1. 9

    Build the Burger

    On the bottom half of the toasted brioche bun, spread Chef Tony's sauce. Top with lettuce, the beef patty with melted cheese, bacon, caramelized onions, fried egg, and tomato slices. Add avocado slices on top.

  2. 10

    Finish and Serve

    Top with the other half of the bun, serve with sweet potato fries on the side, and enjoy!
