1. Preheat your air fryer to 400°F. This ensures your steak starts cooking at the right temperature for a perfect sear outside while keeping the inside juicy.

2. Season the tri-tip steak. Rub the steak all over with olive oil. Mix salt, pepper, garlic powder, and any optional herbs you like in a bowl. Then, evenly coat the steak with this seasoning mix. This step is crucial for flavor enhancement.

3. Place the steak in the air fryer basket. Make sure it’s centered and not touching the sides for even cooking.

4. Cook for about 10 minutes, then flip the steak over to ensure even cooking on both sides. The exact time will depend on your steak’s thickness and your desired doneness.

5. Check for doneness using a meat thermometer. Insert it into the thickest part of the steak. For medium-rare, look for a temperature of 135°F; medium should be around 145°F.

6. Let the steak rest for about 10 minutes after cooking. Cover it lightly with aluminum foil. This step allows the juices to redistribute, making your steak even more tender and flavorful.

7. Slice against the grain and serve. Cutting against the grain ensures each bite is as tender as possible.
