Get to the Point Execution
Cut 1.5 lbs top sirloin into 1-inch cubes. Toss with 1 tbsp olive oil, salt, and pepper.
Preheat air fryer to 400°F. Lay steak bites in single layer with room between.
Air fry for 6-7 minutes, shaking basket once at 4 minutes for medium-rare.
Transfer to bowl, toss with 3 tbsp melted garlic herb butter, and serve immediately.
Step-by-Step Guided Instructions
Trim any thick silver skin from 1.5 lbs top sirloin steak. Cut meat into uniform 1-inch cubes. Pat dry with paper towels.
Cutting uniform 1-inch cubes ensures all bites reach tender medium-rare at the exact same time.
Toss steak cubes with 1 tbsp avocado oil, 1 tsp kosher salt, 1 tsp coarse black pepper, and 1/2 tsp garlic powder.
High-smoke point oil helps transfer convection heat instantly to form a seared crust.
Place steak bites in a single layer in the preheated 400°F air fryer basket without overlapping. Cook for 6 to 7 minutes, shaking the basket at 4 minutes.
Do not crowd the basket; cook in two batches if your air fryer basket is under 6 quarts.
Transfer hot steak bites into a bowl containing 3 tbsp melted salted butter, 2 minced garlic cloves, and 1 tbsp fresh parsley. Toss until glistening.
The hot steak melts the garlic and absorbs the butter during a 2-minute rest.
Top sirloin is the ideal cut for steak bites—lean, tender, flavorful, and half the price of ribeye or tenderloin.
Serve steak bites on toothpick skewers with ketchup or ranch.
