01 - Pat steak cubes dry with paper towels, then toss with olive oil, salt, and black pepper.
02 - Heat a large skillet over medium-high heat. Add steak cubes in a single layer and sear for 2 to 3 minutes until golden brown, turning to brown all sides. Transfer to a plate and set aside.
03 - In the same skillet, add mushrooms. Sauté for 4 to 5 minutes, stirring occasionally, until they release moisture and turn golden.
04 - Lower heat to medium. Add butter, minced garlic, thyme, and parsley to the mushrooms. Stir continuously for 1 minute until fragrant.
05 - Return seared steak and any accumulated juices to the skillet. Toss for 1 to 2 minutes until steak is warmed through and fully coated in garlic butter.
06 - Adjust seasoning as needed. Garnish with additional parsley and serve with lemon wedges if desired.
