This wagyu burger elevated my expectations of fast food! The premium wagyu beef has incredibly rich marbled flavor with a buttery tenderness that melts perfectly against the toasted brioche bun.
Preheat your oven to 225°F. Meanwhile, divide the wagyu ground beef into four 6-oz patties — gently shape without overworking to preserve tenderness and marbling.
Season both sides of each patty evenly with kosher salt, black pepper, garlic powder, and onion powder. Let rest at room temperature for 10 minutes, allowing the seasoning to flavor the meat — a signature Arby’s technique for depth.
Heat a cast iron skillet over medium-high heat. Sear each patty for 2 minutes per side until a brown crust forms; transfer to a baking sheet. Finish burgers in preheated oven for 10 minutes to ensure gentle, uniform doneness — mimicking Arby’s gentle cooking for juicy wagyu texture.
While patties roast, butter the cut sides of the brioche buns and toast, cut side down, in a clean skillet until golden and crisp. This creates the signature buttery bite found in Arby’s premium burgers.
Top each patty with a slice of American cheese in the last 2 minutes of oven roasting so it melts perfectly.
Assemble: Place a leaf of lettuce on the bottom half of each bun, add the cheesy wagyu patty, then layer on slices of tomato and thin red onion. Cap with the top bun. Serve hot for the ultimate Arby's Wagyu Burger experience.
