Air fryer Steak Tips are little steak bite pieces of beef that are well seasoned, then quickly cooked in the Air Fryer. Cooking the steak tips over high heat gives them the beautiful charring that elevates the flavor and will make this your favorite way to cook steak bites.
Preheat the air fryer at 400F for about 5 minutes.
Meanwhile, trim the steak of any fat and cut it into cubes. Then, toss with the ingredients for the marinade (oil, salt, black pepper, Montreal seasoning, onion and garlic powder & the cayenne pepper) and massage the spices into the meat to coat evenly. Do this in a ziplock bag for easier cleanup.
Spray the bottom of the air fryer basket with nonstick spray if you have any and spread the prepared meat along the bottom of it. Cook the beef steak tips for about 4-6 minutes and check for doneness.
Toss the asparagus with 1/2 tsp oil and 1/4 tsp salt until evenly coated.
Once the steak bites are browned to your liking, toss them around and move to one side. Add the asparagus to the other side of the air fryer basket and cook for another 3 minutes.
Remove the steak tips and the asparagus to a serving plate and serve while hot.
*It's safe to open the air fryer at any time to check on the meat. Open the air fryer after about 4-5 minutes of cooking and check to see if it browned to your liking, then cook further or turn the steak pieces and add the asparagus right away, or continue cooking the steak bites for a couple minutes more.
