In a small bowl, combine the olive oil, soy sauce, Dijon mustard, brown sugar (or honey), garlic powder, onion powder, smoked paprika, kosher salt, black pepper, and cayenne pepper (if using). Whisk until well combined.

Place the pork tenderloin in a shallow dish or a resealable bag. Pour the prepared marinade over the pork, ensuring it is fully coated. You can use gloved hands to rub the marinade evenly over the tenderloin. Marinate for at least 10 minutes, or up to 30 minutes for deeper flavor.

While the pork is marinating, preheat your air fryer to 400°F. Preheating is crucial for even cooking and to achieve a desirable crust on the pork.

Once the air fryer is preheated, carefully place the marinated pork tenderloin into the air fryer basket. Ensure there is some space around the tenderloin for air circulation. Cook for 12-15 minutes, flipping halfway through, until the internal temperature reaches 145°F.

Use a meat thermometer to check the internal temperature of the thickest part of the pork tenderloin. It should register 145°F for safe and juicy results. Avoid overcooking, as this can lead to dry and tough pork.

Once cooked, carefully remove the pork tenderloin from the air fryer and transfer it to a cutting board. Let it rest for 5-10 minutes. This resting period allows the juices to redistribute throughout the meat, ensuring a more tender and flavorful result.

After resting, slice the pork tenderloin into thick medallions. Serve immediately, optionally drizzling with any accumulated juices from the cutting board. This dish pairs well with green beans or other roasted vegetables.
