Preparing the Steak Bites: Season the cubed sirloin steak with salt and pepper to taste, ensuring each piece is evenly coated.

Preheat the Air Fryer: Preheat your air fryer to 200°C (392°F) for about 5 minutes.

Air Frying: Once the air fryer is preheated, place the seasoned steak bites in the air fryer basket in a single layer, ensuring there is space between each piece for even cooking.

Cooking: Air fry the steak bites for 8-10 minutes, shaking the basket halfway through the cooking time to ensure they cook evenly and develop a nice brown crust.

Tossing in Butter: Once the steak bites are cooked to your desired level of doneness and have developed a golden brown exterior, transfer them to a mixing bowl. Pour the melted butter over the steak bites and toss gently to coat them evenly in the butter.

Serving: Once coated in butter, transfer the steak bites to a serving plate. Serve hot as a delicious carnivore-friendly snack or meal.
