Instructions
Season the Steak
Pat steak dry and season generously with salt and black pepper.
Sear the Steak Bites
Heat oil in a skillet over high heat. Add steak bites in a single layer and sear 1–2 minutes per side until deeply browned. Work in batches if needed. Remove steak and set aside.
Make the Wasabi Soy Butter
Lower heat to medium. Add butter to the skillet. Once melted, stir in garlic and cook 30 seconds until fragrant. Add soy sauce, honey, and vinegar. Remove from heat and whisk in wasabi paste until smooth.
Toss & Finish
Return steak bites to the skillet and toss until evenly coated in the glossy wasabi soy butter. Cook 30–60 seconds just to warm through.
Serve
Garnish with green onions and sesame seeds. Serve immediately.
Notes
Choose the right cut: Ribeye gives the most richness, while sirloin keeps the dish leaner but still tender when cooked hot and fast.
High heat is key: A very hot pan creates a deep sear and prevents the steak from steaming.
Don’t overcrowd the pan: Cook steak bites in batches so they brown evenly.
Wasabi strength varies: Different brands range from mild to very spicy—start with less and add more gradually.
Add wasabi off heat: Stir it in after removing the pan from direct heat to preserve its fresh, sharp flavor.
Butter balance: Unsalted butter lets you control the saltiness alongside the soy sauce.
