In a large plastic zipper bag, combine the soy sauce, lemon juice, olive oil, brown sugar, Worcestershire sauce, garlic powder, onion powder, and pepper.
Add the roast to the bag, squeeze out any air, then seal the bag shut. Move the roast around in the bag to coat, then refrigerate it for at least 1 hour, up to overnight.
When ready to cook, remove the steak from the bag, discard the marinade, and let it rest at room temperature for 30 minutes.
Preheat the air fryer to 400 degrees F, then cook the steak for 20-24 minutes, or until it reaches your desired level of doneness.
Remove the roast from the air fryer and transfer it to a cutting board. Tent it with foil and allow it to rest for 10 minutes before slicing and serving.
Notes
Let the roast marinate for at least a few hours to allow the beef more time to soak up as much marinade as possible!
Give the roast 30 minutes to come to room temperature before cooking so it doesn’t go into the air fryer completely cold, which can cause uneven cooking.
Let the roast at least 10 minutes to rest under tin foil. This allows the meat to cool, which relaxes the fibers so they can reabsorb their juices.
Slice the tri tip roast against the grain for the best texture. This shortens the meat fibers for maximum tenderness in every bite!
Store leftovers in an airtight container in the fridge for up to 3 days.
Reheat leftovers in a preheated air fryer at 350 degrees F for about 5 minutes until warmed through.
