Prepare the Steak: Season the steak bites with salt and pepper.
Cook the Steak: Heat the olive oil in a large skillet over high heat. Add the steak bites in a single layer (do this in batches if necessary) and cook for about 2-3 minutes per side until they are well-browned and cooked to your desired doneness. Remove the steak from the skillet and set aside.
Make the Garlic Butter Sauce: In the same skillet, reduce the heat to medium. Add 2 tablespoons of butter, the minced garlic, thyme, and rosemary. Cook, stirring frequently, until the garlic is fragrant and lightly golden, about 1-2 minutes.
Combine Steak with Sauce: Return the steak bites to the skillet and toss to coat in the garlic butter sauce. Cook for an additional 1-2 minutes until the steak is heated through and well-coated with the sauce. Remove from heat and stir in the remaining 2 tablespoons of butter until melted.
To Serve:
Plate the Dish: Serve the steak bites over the mashed potatoes. Drizzle any remaining garlic butter sauce from the skillet over the top.
Garnish: Sprinkle with fresh parsley and chives, if desired.
Enjoy!
