01 - Pat steak cubes dry with paper towels. Toss with olive oil, salt, and pepper to coat evenly.
02 - Heat a large skillet over medium-high heat until hot. Place steak cubes in a single layer and sear for 2 to 3 minutes until golden brown on all sides. Remove and set aside.
03 - Add mushrooms to the same skillet and cook for 4 to 5 minutes, stirring occasionally until they release moisture and turn golden.
04 - Reduce heat to medium. Stir in butter, minced garlic, thyme, and parsley. Cook for 1 minute until fragrant.
05 - Return steak cubes and any collected juices to the skillet. Toss for 1 to 2 minutes until steak is heated through and coated with garlic butter sauce.
06 - Adjust seasoning to taste. Garnish with additional parsley and serve with lemon wedges if desired.
