Prepare the Steak: Pat the steak pieces dry with a paper towel and season with salt and pepper. This helps achieve a nice sear when cooking.
Sear the Steak: In a large skillet, heat the olive oil over medium-high heat. Once hot, add the steak bites in a single layer, ensuring not to overcrowd the pan. Sear for about 2-3 minutes on each side until browned and cooked to your desired doneness. Remove the steak bites from the skillet and set aside.
Make the Garlic Butter: In the same skillet, lower the heat to medium. Add the butter and let it melt. Add the minced garlic and cook for about 30 seconds until fragrant, being careful not to let it burn.
Combine Ingredients: Return the steak bites to the skillet, along with the chopped parsley and red pepper flakes (if using). Toss everything together until the steak is well-coated with the garlic butter.
Add Cheese: Sprinkle the grated Parmesan cheese over the steak bites and toss once more to ensure the cheese melts slightly and coats the steak.
Serve: Taste and adjust seasoning if needed. Serve hot, garnished with additional parsley if desired.
Notes
Adjust seasoning to taste and serve hot for the best flavor.
