To create the delicious Cajun Garlic Butter Steak Bites, follow these simple steps for a perfect outcome:

1. Prepare the Steak: Start by cutting the sirloin steak into bite-sized pieces. Pat dry with paper towels to eliminate excess moisture.
2. Season the Steak: In a bowl, combine the steak pieces with Cajun seasoning, salt, and pepper. Ensure that the steak is evenly coated.
3. Heat the Pan: In a large skillet over medium-high heat, add olive oil and heat until shimmering.
4. Cook the Steak Bites: Add the seasoned steak pieces in a single layer, ensuring not to crowd the pan. Cook for 2-3 minutes until browned.
5. Flip and Cook: Rotate the steak bites and cook for an additional 2-3 minutes, until they reach your desired level of doneness. Remove the steak from the pan and set aside.
6. Make the Garlic Butter: In the same skillet, reduce the heat to medium. Add the butter and minced garlic, stirring until the garlic becomes fragrant (about 1 minute).
7. Combine: Stir in the Worcestershire sauce and return the cooked steak to the skillet, tossing everything to coat in the garlic butter. Heat for an additional 1-2 minutes.
8. Finish with Garnish: Taste and adjust seasoning if needed. Remove from the heat, sprinkle with chopped parsley, if desired, and serve immediately.
