Season the meat. Sprinkle the cubed steak with salt and pepper to taste on all sides.
Place a large pan or a cast iron skillet over high heat. Let it heat for 2 to 3 minutes or until hot. Add the olive oil and let it heat for another minute.
Add the steak and cook for 3 to 4 minutes, occasionally stirring until browned on all sides. Remove it from the pan and set it aside.
Add the butter to the same pan and let it melt completely. Gently scrape the bottom of the pan with a wooden spoon. Reduce the heat to medium. Add the garlic and dried rosemary. Stir constantly and cook the mixture for 30 seconds or until nice and fragrant. Don't burn the garlic.
Return the cooked steak bites to the pan and baste them in the garlic butter for 1 to 2 minutes for a medium-rare steak. Please feel free to baste for an additional minute or so if you like your steak a little more cooked.
Remove the skillet from the heat. Taste the steak bites for salt and pepper and adjust.
Garnish the dish with fresh parsley Generously season the meat with salt and pepper to taste on all sides. Set it aside.
Prepare the pan. Place a large pan over medium-high heat; a cast iron skillet is preferred. Let it heat for 2-3 minutes. Add the olive oil and let it heat for another minute. Don’t skip this step because cold oil won’t make beautifully browned steak bites. It needs to be hot. If your pan is smoking, reduce the heat
Brown the steak. Add the meat and let it cook for 3-4 minutes, stirring occasionally, or until browned on all sides. Remove it from the pan and set it aside
Melt the butter. Add the butter to the same pan and let it melt completely. Gently scrape the bottom of the pan with a wooden spoon. Reduce the heat to medium. Add the garlic and dried rosemary. Stir. Cook the mixture for 30 seconds or until nice and fragrant. Don’t let the garlic burn
Baste it. Return the cooked steak bites to the pan and baste them in the garlic butter for 1-2 minutes for a medium rare. Baste for an additional 1-2 minutes if you like your steak a little more cooked. Basting is basically spooning a sauce over an ingredient as it cooks.
Serve. Remove it from the heat. Season with more salt and pepper to taste. Garnish the dish with fresh parsley to taste.
