Ingredients

Wagyu Roast Beef and Toppings

Preparation

Roasting and warming Wagyu

1. Roast preparation (optional from raw)

If starting from a raw Wagyu roast, slow-roast in a preheated oven at 225-250°F (110-120°C) until an internal temperature of 130-135°F (54-57°C) for medium-rare. Remove from heat and let rest 15-20 minutes before thinly slicing.

2. If starting from pre-roasted beef

If using already roasted Wagyu, gently rewarm slices in a skillet over low heat or in a warm oven just until heated through. Avoid overheating to preserve tenderness.

3. Slice beef

Thinly slice the beef to about 1/16 inch thickness for tender, even stacking on the sub.

Assemble the Cold Wagyu Beef Sub

4. Prepare rolls

Split the rolls lengthwise and lightly toast if desired for texture and flavor. Spread about 1/2 tablespoon of mayonnaise on the inside of each roll.

5. Layer beef

Pile a generous portion of the Wagyu roast beef onto each roll, creating a heaping layer.

6. Add cheese and melt slightly

Top the beef with provolone slices. If desired, briefly melt the cheese by returning the assembled halves to a warm oven or under a broiler for 1-2 minutes until cheese just begins to melt.

7. Add vegetables

Top with lettuce, tomato slices, and onion slices. Lightly season with salt and pepper to taste.

8. Finish and serve

Close the sandwich, slice in half if preferred, and serve immediately.
