Keep sirloin steak in refrigerator until you are ready to cook. This will ensure it does not cook the middle too fast.

Potatoes

In a large skillet, melt butter and garlic over medium high heat.

Add potatoes to skillet and toss in garlic and butter.

Stir in salt, pepper, and parsley.

Cover and cook for 15 minutes.

Take potatoes out and sit to the side.

Steak Bites

Turn heat down to medium.

In the same skillet, melt butter and garlic.

Stir in sirloin steak.

Toss in Worcestershire sauce, salt, pepper, and parsley.

Cook for about 8 minutes.

Add potatoes back to the skillet and cook for another 8-10 minutes.

Test pieces of steak to see if it has your desired pinkness.
