Pat the steak cubes dry with paper towels to ensure proper searing. Season generously with salt and black pepper.

Heat olive oil in a large skillet over medium-high heat. Once hot, add the steak bites in a single layer. Avoid overcrowding the pan; cook in batches if necessary.

Sear the steak bites for 2–3 minutes on each side until browned and cooked to your desired doneness. Remove steak from the skillet and set aside.

Reduce heat to medium. Add butter to the skillet and allow it to melt. Add minced garlic, thyme, and rosemary, sautéing for 1–2 minutes until fragrant.

Return the steak bites to the skillet and toss in the garlic butter and herbs until well-coated. Cook for an additional 1–2 minutes to heat through and absorb flavors.

Stir in fresh parsley just before serving for added color and freshness.

Serve immediately with your choice of sides.
