In a medium bowl, I added avocado oil, steak, Worcestershire, and seasonings . Toss to combine.
Preheat the Air Fryer to 400 degrees Fahrenheit. If your Air Fryer doesn’t have a preheat function, set it to 400 degrees Fahrenheit and set the timer to 7 minutes. Check doneness after 7 minutes. I like it rare especially if using as meal prep because it will cook when reheating.
When the Air Fryer is preheated add the steak bites to the Air Fryer basket and cook for four minutes.
While the steak is cooking, place the skillet on the stovetop. Melt butter in a skillet. When butter is melted, add garlic to the skillet, cook for about 30 seconds while stirring, just until the garlic becomes aromatic and starts to brown. Remove from heat.
When steak is done add to garlic butter, and parmesan, toss to coat.
