A5 Wagyu Steak Bites with Soy-Cured Egg Yolk

This is the definitive way to cook A5 Wagyu steak bites without ruining them. The secret is a screaming-hot dry griddle, a short sear, and a silky soy-cured egg yolk to finish.

Each cube develops a lacy, golden crust while the interior stays tender and rich. A touch of fresh wasabi cuts through the fat. It’s a quick, luxurious bite that feels like teppanyaki at home.

A5 Wagyu is prized for its intense marbling and buttery texture. The key is to let the meat shine with minimal intervention.

Here, chilled cubes are seasoned with flaky salt, seared briefly on a dry hot surface, and finished with a glossy egg yolk cured in tamari and mirin.

The result is a perfect balance of crispy exterior, molten interior, and umami-rich sauce. Serve as an appetizer or a main with steamed rice.

Ingredients

Why this recipe works

Curing the egg yolks in tamari and mirin transforms them into a thick, savory sauce. The soy adds depth, while the mirin brings sweetness and viscosity. As the yolks sit in the marinade, they absorb flavor and become slightly firmer, making them perfect for dipping.

Searing at 450°F (232°C) on a dry surface allows the wagyu’s own fat to render and create a crispy crust.

The high heat ensures the outside browns quickly while the inside stays tender. Resting the meat afterward lets the juices redistribute, so every bite is moist and flavorful.

Notes and substitutions

A5 Wagyu is heavily marbled, so no additional oil is needed. If you can’t find A5, look for other well-marbled cuts like ribeye or striploin from high-quality beef. The flaky sea salt is crucial; it adds texture and a clean saltiness that enhances the meat.

The aged tamari and mirin are essential for the cured yolk. Use a good-quality tamari, and if you’re gluten-sensitive, choose a gluten-free version. Mirin adds a mild sweetness; if you don’t have it, substitute with a mixture of dry sherry and a pinch of sugar.

• A5 Wagyu striploin: A5 ribeye or other well-marbled wagyu cut; or high-quality prime beef striploin if A5 is unavailable.
• Aged tamari: Regular tamari or soy sauce; use gluten-free tamari if needed.
• Mirin: Sweet sherry or a mix of 1 tbsp dry sherry and 1 tsp sugar per tablespoon of mirin.
• Fresh wasabi: Prepared wasabi paste (from a tube) or grated horseradish mixed with a little soy sauce.
