Ingredients
Method
- For Beef Tenderloin: Preheat oven to 130°C (275°F). Rub beef with oil, season with salt, and place on a rack over a tray.
- Roast 18–20 minutes until center reaches 41°C (105°F). Check at 15 minutes to avoid overcooking.
- Sear each side in a smoking-hot skillet for 10 seconds to form a crust. Cool 30 minutes, then refrigerate uncovered for 2 hours.
- Slice beef into 3 mm (1/16") thin slices with a sharp knife.
- For the Dressing: Simmer sake and mirin for 1 minute. Cool, then whisk in soy sauce, vinegar, and yuzu (or lime/lemon).
- For Garlic Oil (optional): Cook garlic slices in oil over low heat for 5 minutes until pale golden. Cool, strain, and set aside.
- Assemble: Arrange beef slices slightly overlapping on a platter. Drizzle with dressing and garlic oil. Top with crispy potatoes or shallots, and garnish with green onion. Serve immediately.
- Easy Sirloin Option: Rub steak with oil and salt. Sear 1½–2 minutes per side (rare). Cool, slice thinly, and serve as above.
Notes
Use tamari for gluten-free. Yuzu can be substituted with lime + lemon. Slice beef thinly for best texture. Prep ahead by making beef and dressing in advance, then assemble before serving.
