A delightful and easy-to-make skillet sirloin recipe with a rich mushroom thyme sauce, perfect for a quick and satisfying meal.
Cut the sirloin steak into four equal portions.
Cutting the steak into portions ensures even cooking and makes serving easier.
Heat a large skillet over medium-high heat and add a drizzle of oil.
Ensure the skillet is hot before adding the steaks to achieve a good sear.
Sear the steak portions for about 4-5 minutes on each side until browned. Remove and set aside.
Let the steaks rest after searing to lock in their juices.
In the same skillet, add the sliced onion and mushrooms. Sauté for 3-4 minutes until softened.
Stir occasionally to prevent sticking and ensure even cooking.
Add the beef broth, Dijon mustard, Worcestershire sauce, thyme, and garlic powder to the skillet. Stir well and bring to a boil.
Mix the sauce ingredients thoroughly to combine the flavors.
Reduce the heat and let the sauce simmer for 2-3 minutes to thicken slightly.
Simmering allows the flavors to meld and the sauce to reduce.
Return the steak portions to the skillet, spoon the sauce over them, and cook for an additional 2 minutes.
Coating the steaks in the sauce enhances their flavor.
Serve the steaks hot with the mushroom thyme sauce spooned generously over them.
Garnish with fresh thyme or parsley for a touch of color and freshness.
