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. Add steak cubes in a single layer and sear for 2 to 3 minutes, turning to brown all sides. Remove steak and set aside.
03 - In the same skillet, add quartered mushrooms. Sauté for 4 to 5 minutes, stirring occasionally, until they release moisture and turn golden.
04 - Reduce heat to medium. Add butter, minced garlic, thyme, and parsley to the mushrooms. Stir continuously for 1 minute until fragrant.
05 - Return steak bites and any accumulated juices to the skillet. Toss with the garlic butter sauce for 1 to 2 minutes until heated through and well coated.
06 - Adjust seasoning to taste. Garnish with additional parsley and serve immediately with optional lemon wedges.
