Instructions

In a bowl, whisk together soy sauce, olive oil, Sriracha, and cracked pepper. Add steak strips and marinate for at least 30 minutes.
Melt 1 tablespoon butter in a skillet over medium-high heat. Season steak strips with salt and pepper, then sear for 1–2 minutes per side. Transfer to a plate and cover.
Lower heat to medium. Add shallot and garlic; cook until softened, about 2 minutes. Stir in thyme, chives, and chili flakes.
Add lemon juice, Dijon mustard, and beef stock, scraping up any browned bits. Optionally stir in remaining marinade. Let sauce reduce by half, about 5 minutes.
Stir in the remaining 2 tablespoons butter until melted and the sauce is silky. Taste and adjust seasoning.
Return steak to the pan to coat in the sauce. Garnish with parsley and extra chives. Serve hot with your choice of sides.

Notes

Use high heat and quick searing to avoid overcooking the steak.
Adjust heat level by varying the amount of Sriracha or chili flakes.
For a richer finish, add a splash of cream at the end.
Serve with fresh vegetables or mashed potatoes for a balanced meal.
