Servings : 4 servings
Prep Time 10 minutes
Cook Time 10 minutes
Resting Time 5 minutes
Total Time 25 minutes


  • 1 to 1.5 pounds sirloin steak, cut into 2-inch cubes
  • ½ teaspoon salt, or to taste
  • ¼ teaspoon fresh ground black pepper, or to taste
  • 1 teaspoon smoked or sweet paprika, or to taste
  • 1 teaspoon garlic powder
  • 1 teaspoon Italian Seasoning
  • 2 tablespoons vegetable oil, divided
  • 4 tablespoons butter, divided
  • 4 cloves garlic, minced, divided
  • 8 ounces sliced mushrooms
  • chopped fresh parsley, for garnish


  • Place steak cubes in a mixing bowl; season with salt, pepper, paprika, garlic powder, and Italian Seasoning. Toss to combine.
  • Heat 1 tablespoon vegetable oil in a large cast iron skillet or a heavy-bottomed skillet over medium-high heat. Add the steak bites to the hot skillet in a single layer. If it doesn't sizzle, the skillet is not hot enough.
  • Sear the steak bites for 1 minute - do not move them around. Using tongs or a spatula, flip the steak bites over; add 2 tablespoons butter and stir in half of the minced garlic. Continue to cook for 1 to 2 more minutes or until the steak is done. Do not overcook the steak.
  • Transfer the steak bites to a plate and keep them covered.
  • Add remaining vegetable oil to the skillet and heat over medium-high heat. Stir in the sliced mushrooms and season with salt and pepper. Cook for 3 minutes, or until browned.
  • Add remaining butter and stir in the rest of the garlic; let cook for 2 to 3 more minutes or until soft. Stir the steak and drippings back into the skillet and cook for 30 more seconds or until heated through.
  • Remove from heat and let stand for 5 minutes.
  • Garnish with parsley and serve.


  • Skillet Choice: A cast-iron skillet retains heat well and provides a consistent sear, but if you don't have one, any heavy-bottomed pan will do. If your skillet isn't big enough, you may have to cook the steak bites in 2 to 3 batches.
  • Steak: If you can’t find/don’t have Sirloin Steak, you can also use Rib Eye, New York Strip, or Tenderloin Steak.
  • Seasonings: While the recipe provides specific seasonings, feel free to adjust or add according to what you like.
  • Storing Leftovers: If you have any leftovers, store them in an airtight container in the refrigerator. Reheat gently to avoid overcooking the steak.
