📝 About This Recipe

Experience the pinnacle of luxury with A5 Japanese Wagyu, a masterpiece of genetic marbling and buttery texture that melts at room temperature.

Enhanced by a touch of fresh wasabi and flakey sea salt, this dish offers a transcendent dining experience that redefines the meaning of a perfect steak.

🥗 Ingredients

The Star

  • 12 ounces A5 Japanese Wagyu Striploin (cut 3/4 to 1 inch thick, chilled until ready to sear)

Seasoning and Aromatics

  • 1 teaspoon Maldon Sea Salt (flaky texture is essential)
  • 1/2 teaspoon Freshly Cracked White Pepper (more delicate than black pepper)
  • 2 pieces Garlic Cloves (thinly sliced into chips)
  • 1 piece Beef Tallow or Wagyu Fat Trim (cut from the edge of the steak)

Traditional Accompaniments

  • 1 inch Fresh Wasabi Root (grated on a sharkskin or fine grater)
  • 1 tablespoon Shio Koji (for a subtle fermented umami boost)
  • 1 tablespoon High-Quality Soy Sauce (preferably aged or 'shoyu')
  • 1/4 cup Micro-greens or Daikon Sprouts (for a peppery garnish)

👨‍🍳 Instructions

  1. 1

    Remove the Wagyu from the refrigerator exactly 15 minutes before cooking. Unlike traditional beef, Wagyu fat has a very low melting point; you want it slightly tempered but still firm to the touch.

  2. 2

    Trim a small 1/2-inch cube of pure white fat from the edge of the striploin. Set this aside to use as your cooking oil.

  3. 3

    Pat the surface of the steak extremely dry using paper towels. Moisture is the enemy of a perfect crust.

  4. 4

    Season only with a light dusting of white pepper. Hold off on the salt until the very end to prevent drawing out moisture during the sear.

  5. 5

    Place a heavy stainless steel or cast iron skillet over medium-high heat. Allow the pan to get hot enough that a drop of water dances and evaporates instantly.

  6. 6

    Place the reserved fat cube in the pan using tongs. Rub it around the surface as it renders, coating the bottom of the pan in a thin layer of liquid gold.

  7. 7

    Add the garlic slices to the rendered fat. Fry for 30-45 seconds until golden brown and crisp. Remove the garlic chips and set aside on a paper towel.

  8. 8

    Carefully lay the Wagyu striploin into the pan. Sear for 60-90 seconds without moving it. You are looking for a deep, mahogany crust.

  9. 9

    Flip the steak gently using tongs. Sear the second side for another 60-90 seconds. For A5 Wagyu, a 'Medium-Rare' to 'Medium' (125°F - 130°F) is ideal to ensure the fat is fully rendered.

  10. 10

    Using tongs, stand the steak on its side to sear the fat cap for 30 seconds, ensuring every edge is beautifully browned.

  11. 11

    Remove the steak from the pan and place it on a warm plate or cutting board. Let it rest for at least 5 minutes. This allows the internal juices to redistribute.

  12. 12

    While resting, grate the fresh wasabi root into a small paste.

  13. 13

    Slice the Wagyu into 1/2-inch thick strips against the grain. Sprinkle generously with the Maldon sea salt flakes now.

  14. 14

    Arrange the slices on a plate, topping each with a crispy garlic chip and a small dollop of fresh wasabi.

💡 Chef's Tips

Never use butter or seed oils; the rendered Wagyu fat provides the best flavor and highest smoke point for this specific meat. Do not overcook; A5 Wagyu is best enjoyed at medium-rare to medium so the intramuscular fat actually melts into the meat. If you cannot find fresh wasabi, use a high-quality paste, but avoid the bright green 'horseradish' powders if possible. Always slice against the grain to ensure the shortest muscle fibers and the most tender bite. Use a very sharp knife to avoid pressing down on the meat and squeezing out the precious juices.

🍽️ Serving Suggestions

Pair with a crisp, acidic Junmai Daiginjo Sake to cut through the richness of the fat. Serve alongside a bowl of fluffy, short-grain Japanese white rice to soak up the rendered oils. A simple side of pickled daikon or cucumber sunomono provides a refreshing vinegar contrast. For wine lovers, a high-tannin Cabernet Sauvignon or a vintage Bordeaux works beautifully. Finish the plate with a small pool of aged soy sauce mixed with a drop of shio koji for dipping.
