Start by placing the sirloin steak cubes in a large mixing bowl. Add the olive oil, kosher salt, black pepper, garlic powder, onion powder, smoked paprika, and Italian seasoning. Toss everything together until each piece of steak is evenly coated with the oil and spices. This ensures that every bite is packed with flavor.
Let the seasoned steak rest for about 10 minutes while you preheat your air fryer to 400°F (200°C). Preheating is crucial as it ensures that the steak bites cook evenly and get that perfect crisp on the outside.
Once the air fryer is preheated, place the seasoned steak bites in the basket in a single layer. It's important not to overcrowd the basket; if needed, cook in batches. This ensures proper air circulation and even cooking.
Set the timer for 5 to 10 minutes. The exact cooking time will depend on how you like your steak cooked. For medium-rare, check the doneness around the 5-minute mark. You’ll want to shake the basket every couple of minutes to promote even cooking.
When the steak bites are done and reach your desired doneness, carefully remove them from the air fryer. It’s best to use tongs for this step to keep from burning your fingers!
While the steak bites are still warm, toss them in the melted butter. This adds richness and a luxurious touch to the dish.
Finally, sprinkle the cooked steak bites with chopped fresh parsley just before serving. Not only does this make the dish look appealing, but it also adds a fresh flavor that balances the richness of the steak.
Serve immediately while they’re hot and crispy! You can enjoy these Air Fryer Steak Bites on their own or with your favorite dipping sauces.
If you have leftovers, store them in an airtight container in the refrigerator. They’re delicious the next day, too!
