A quick and easy recipe featuring tender sirloin steak bites seared to perfection and coated in a rich garlic butter sauce with earthy mushrooms. Perfect for busy weeknights or casual dinners.

Ingredients

Scale
  • 1 lb sirloin steak, trimmed and cut into 1-inch cubes
  • Salt and freshly ground black pepper, to taste
  • 1 tablespoon olive oil
  • 3 tablespoons unsalted butter, divided and softened
  • 4 cloves garlic, minced
  • 1 teaspoon fresh thyme leaves (or ½ teaspoon dried thyme)
  • 1 tablespoon chopped fresh parsley
  • 8 oz cremini or baby bella mushrooms, sliced
  • Salt and pepper, to taste

Instructions

  1. Pat the sirloin cubes dry with paper towels. Season generously with salt and freshly ground black pepper. Let sit at room temperature for about 10 minutes.
  2. Heat a large heavy-bottomed skillet or cast iron pan over medium-high heat. Add 1 tablespoon olive oil and heat until shimmering but not smoking, about 2 minutes.
  3. Add the sirloin cubes in a single layer without overcrowding. Sear each side for about 2 minutes until a deep brown crust forms. Aim for medium-rare to medium doneness (about 135°F internal temperature). Remove steak bites and set aside on a warm plate.
  4. In the same skillet, add 1 tablespoon butter. Once melted, add the sliced mushrooms in an even layer. Season with salt and pepper. Cook without stirring for 3 minutes, then stir and cook another 3 minutes until golden and tender.
  5. Lower heat to medium. Push mushrooms to one side and add remaining 2 tablespoons butter. When butter foams and browns slightly, add minced garlic and thyme leaves. Stir quickly and cook for about 1 minute, being careful not to burn the garlic.
  6. Return steak bites to the pan. Toss gently for 1-2 minutes to coat meat and mushrooms in garlic butter sauce. Adjust seasoning if needed.
  7. Remove from heat, sprinkle with fresh parsley, and serve immediately while warm.

Notes

Dry the steak cubes well before cooking to ensure a good sear. Avoid overcrowding the pan when cooking steak and mushrooms to promote browning instead of steaming. Brown the butter carefully to add a nutty flavor without burning. If skillet dries out, add a splash of beef broth or more butter. Leftovers keep well refrigerated for up to 3 days and reheat gently with added butter or broth.
