Prep Time10 minutes

Chill Time15 minutes
Total Time31 minutes
Servings: 4 servings

Ingredients

  • 16 oz sirloin steak cut into bite-sized pieces
  • 2 teaspoons olive oil
  • 1/4 teaspoon salt
  • 1/4 teaspoon pepper
  • 1/4 teaspoon onion powder
  • 1/4 teaspoon garlic powder
  • 1/2 teaspoon brown sugar

For the Garlic Butter

  • 1-2 cloves garlic minced
  • 3 tablespoons salted butter
  • 1 teaspoon parsley chopped

Instructions

  • Cut the sirloin into bite-sized pieces, keeping them roughly the same size so they cook evenly.
  • In a bowl, whisk together the olive oil, salt, pepper, onion powder, garlic powder, and brown sugar.
  • Add the steak pieces to the bowl and toss until evenly coated. Let them sit for 15-20 minutes to soak up the flavor.
  • Preheat the air fryer to 400°F (200°C).
  • Arrange the marinated steak in a single layer in the basket, leaving space between pieces so air can circulate.
  • Air fry for 4-6 minutes, checking for your preferred doneness.
  • While the steak cooks, melt the butter in a microwave-safe bowl, then stir in the minced garlic and parsley.
  • Transfer the cooked steak to a serving plate and pour the garlic butter sauce over the top, tossing to coat.
  • Let it rest for a couple of minutes so the flavors settle in, then serve hot.

Notes

Store leftovers in an airtight container in the fridge for up to 3 days.
Reheat gently in a skillet over medium heat or back in the air fryer for a couple minutes — the microwave can make the steak tough.
Great served over rice, mashed potatoes, or tossed into a salad.
Double the garlic butter if you like extra sauce for dipping or drizzling.
