01 - Pat steak cubes dry with paper towels to remove excess moisture. Sprinkle with kosher salt, black pepper, and smoked paprika, ensuring all sides are well coated.
02 - Heat a large skillet or cast-iron pan over high heat. Add 1 tablespoon of butter; once melted and foaming, arrange half of the steak cubes in a single layer. Sear for 1–2 minutes per side until deeply browned and cooked to desired doneness. Transfer to a plate and repeat with remaining steak, adding a splash of oil if skillet becomes too dry.
03 - Reduce heat to medium-low. Add remaining 2 tablespoons butter and minced garlic to the same pan. Stir continuously for about 30 seconds until aromatic but not browned.
04 - Return all seared steak bites to the skillet. Toss gently to ensure each piece is coated with garlic butter. Stir in chopped fresh parsley and thyme leaves.
05 - Serve steak bites immediately, garnished with flaky sea salt and extra parsley if desired.
