Indulge in a gourmet Wagyu beef burger featuring rich bone marrow, sweet caramelized onions, a gooey sunny-side-up egg, and melted cheddar inside a toasted brioche bun.

Ingredients

• 600 g minced Wagyu beef
• 80 g beef bone marrow
• 40 g shallots
• 30 g breadcrumbs
• 1 egg
• 20 ml dark beer
• 2 onions
• 30 g butter
• 5 g salt
• 10 g sugar
• 15 ml Italian balsamic vinegar
• 4 slices cheddar cheese
• 2 eggs
• 2 brioche burger buns
• 30 ml honey mustard sauce
• 20 g arugula
• 4 slices tomato
• 4 slices pickles

Instructions

1. 1Add Beef Bone Marrow

   

   Add finely chopped beef bone marrow directly into the bowl containing the minced Wagyu beef to boost the fat aroma, moisture, and overall richness of the burger patties.

   Tip: Ensure the bone marrow is finely chopped so it distributes evenly throughout the minced meat.
2. 2Chop and Add Shallots

   

   Finely chop the shallots on a cutting board using a chefs knife while wearing protective gloves. Add the chopped shallots to the meat mixture to enhance the onion aroma and texture.

   Tip: Dice the shallots uniformly to ensure consistent flavor distribution in every bite.
3. 3Add Breadcrumbs and Egg

   

   Add a small amount of breadcrumbs and an egg into the mixing bowl with the beef and shallot mixture. These act as binding agents to help hold the patties together.

   Tip: Add the breadcrumbs gradually to avoid making the patty mixture too dense.
4. 4Pour Dark Beer

   

   Pour a measured amount of dark beer into the mixing bowl over the meat and binders. The dark beer introduces moisture and depth of flavor before mixing everything together thoroughly.

   Tip: Pour in a steady stream to distribute the liquid evenly across the ingredients.
5. 5Portion and Shape Patties

   

   Thoroughly mix and beat the seasoned beef mixture until firm, then portion and shape it into individual round meat patties weighing about 150 grams each before moving them to the refrigerator.

   Tip: Use a digital kitchen scale to ensure each patty is precisely 150 grams for even cooking times.
6. 6Sauté the Onions in Butter

   

   Add the sliced onions into a pan with melted butter and stir-fry evenly to start building the flavor base for the caramelized onions.

   Tip: Ensure the butter is fully melted before adding the onions to prevent sticking and ensure even coating.
7. 7Season the caramelized onions

   

   Add salt, sugar, and Italian balsamic vinegar to the cooking onions to build flavor and balance the sweetness.

   Tip: Add the balsamic vinegar gradually to control the acidity.
8. 8Press and sear the meat patty

   

   Place a prepared meat patty onto an oiled griddle and press it flat using a spatula to ensure even cooking.

   Tip: Press down firmly once when placing the patty to get a good crust.
