1.5 to 1.75 lbs. Sirloin steak, cut into bite-sized pieces
Salt and pepper, as needed
Olive oil, for cooking
16oz. fresh mushrooms, sliced (you can use any kind you like)
5 TBSP unsalted butter
1/2 tsp crushed red chili flakes (or to taste)
3 to 4 cloves garlic, grated or minced
1 TBSP Worcestershire sauce or soy sauce
Instructions
Season the steak with salt and pepper.
Add a couple/few tablespoons of olive oil to a large skillet set over high heat. When it shimmers, add the steak bites, in a single layer (no overlapping or they won’t brown). When it’s all in the pan, don’t touch or move it for about 2 minutes, so the meat has a chance to really get brown. It will end up looking gray, otherwise (a good steak cooking tip in general).
After two minutes, stir/turn the steak and continue cooking just until browned all over. You want it pink in the middle, still. Transfer to a tray or large plate and set aside for now. Don’t clean out the pan.
Reduce the heat to medium. Add the mushrooms to the pan and, just like the steak, don’t touch them for a couple of minutes before stirring. Allow them to cook until tender; about 3 to 5 minutes. Season lightly with salt and pepper, and transfer to the tray with the steak. Don’t wipe out the pan.
With the heat on med-low, add the butter, garlic, chili flakes, 2 TBSP olive oil, and the Worcestershire sauce or soy sauce to the pan and cook, stirring for about a minute. Turn off the heat, add the steak and mushrooms back into the pan (and all of the collected juices), and stir to coat in the butter sauce. Serve right away.Â
