  • 1 to 1.5 pounds Sirloin Steak, cut into 2-inch cubes
  • 1/2 teaspoon salt, or to taste
  • 1/4 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 mushrooms, sliced
  • 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 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 done. DO NOT OVERCOOK.
  • Transfer steak bites to a plate and keep 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 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.
  • Let stand 5 minutes.
  • Garnish with parsley and serve.


  • If your skillet isn't big enough, you may have to cook the steak bites in 2 to 3 batches.
  • If you can’t find/don’t have Sirloin Steak, you can also use Rib Eye, New York Strip, or Tenderloin Steak.
