Creating amazing Garlic Butter Steak Bites is straightforward if you follow these steps:

1. Prepare the Steak: Cut the sirloin steak into bite-sized cubes. Pat them dry with paper towels to ensure a good sear. Season with salt and pepper on all sides.
2. Melt Butter: In a large skillet, melt the 4 tablespoons of unsalted butter over medium heat.
3. Heat Oil: Add the teaspoon of olive oil into the skillet to prevent the butter from burning.
4. Cook the Steak: Once the butter has melted and is bubbling, add the steak bites in a single layer. Avoid overcrowding to achieve a nice sear. Sear for about 2-3 minutes on each side until browned and cooked to your desired doneness.
5. Add Garlic: Add the minced garlic to the pan during the last minute of cooking, stirring frequently to avoid burning.
6. Toss to Coat: Once cooked, toss the steak in the melted garlic butter for even distribution.
7. Garnish: Remove the pan from heat. Optionally sprinkle with chopped parsley for added flavor and color.
8. Serve Immediately: Transfer the garlic butter steak bites to a serving platter while they are still hot.

By following these simple steps, you will have created a delicious, restaurant-quality dish that showcases a wonderful combination of garlic and steak.
