Step 1: Pat the steak cubes thoroughly dry with paper towels. Season generously on all sides with salt and freshly ground black pepper.
Step 2: Heat a large, heavy-bottomed skillet (preferably cast iron) over medium-high heat. Add 1 tablespoon of olive oil. Once the pan is hot and slightly smoking, add half of the steak cubes in a single layer, ensuring not to overcrowd the pan.
Step 3: Sear the steak for 1-2 minutes per side until a deep golden-brown crust forms. Remove the seared steak to a clean plate. Repeat with the remaining steak cubes, adding another tablespoon of olive oil if needed.
Step 4: Once all the steak is seared and removed from the pan, reduce the heat to medium-low. Add the butter, minced garlic, fresh rosemary sprigs, and fresh thyme sprigs to the pan. Cook, stirring frequently, until the butter is melted and fragrant, about 1 minute. Be careful not to burn the garlic.
Step 5: Return all the seared steak bites to the pan. Spoon the garlic herb butter over the steak, tossing gently to coat all the pieces. Cook for another 30 seconds to 1 minute, just to warm the steak through and ensure it’s fully coated in the sauce.
Step 6: Remove the pan from heat. Stir in the fresh chopped parsley. Taste and adjust seasoning if necessary. Serve immediately and enjoy your perfect garlic butter steak bites!
