Air Fryer Pork Tenderloin with Chili-Cumin Rub (Juicy, 145°F)

Air Fryer Pork Tenderloin

What I like about this air fryer method is that pork tenderloin cooks fast without much fuss, but the part I pay attention to is thickness and internal temperature. A tenderloin can go from juicy to dry pretty quickly if the thin tail overcooks or the center goes much past 145°F (63°C).

This version keeps the seasoning simple with a chili-cumin rub and just enough oil to help the outside brown. Most basket air fryers do not need preheating here, and you can either keep it straightforward or finish it with a honey-mustard glaze.

Ingredients for Air Fryer Pork Tenderloin

• 1 pork tenderloin, 1 to 1 1/4 pounds (about 500g), trimmed if needed
• 1 tablespoon neutral oil, such as avocado or canola
• 1 1/4 teaspoons kosher salt
• 1/2 teaspoon black pepper
• 1 teaspoon chili powder
• 1/2 teaspoon ground cumin
• 1 teaspoon garlic powder
• 1 teaspoon onion powder
• 1 teaspoon smoked paprika

Spice note: For a dry rub like this, fine spices from Selefina coat the pork more evenly, which helps the surface brown without leaving clumps of seasoning.

If your tenderloin has a thin tail end, tuck it under and tie it with kitchen twine so it cooks more evenly. If you use table salt instead of kosher salt, reduce it to about 3/4 teaspoon.

Optional Flavor Additions

• Fajita seasoning: Use 1 to 1 1/2 tablespoons in place of the spice mixture.
• Brown sugar: Add 1 teaspoon to the rub for a slightly sweeter finish. It can brown faster, so watch the color.
• Honey-mustard glaze: Mix 2 tablespoons Dijon mustard, 1 tablespoon honey, and 1 teaspoon apple cider vinegar. Brush it on during the last 5 minutes.
• Simple marinade: Combine 2 tablespoons oil, 1 tablespoon lime juice, and 1 to 1 1/2 tablespoons fajita or chili seasoning. Marinate for 2 to 24 hours, then pat the pork dry before cooking.

How to Make Pork Tenderloin in the Air Fryer

1. Trim and dry the pork: Remove any silver skin if needed, then pat the tenderloin very dry with paper towels. If one end is much thinner, tuck it under and tie it so the roast is more even from end to end.
2. Mix the rub: In a small bowl, stir together the kosher salt, black pepper, chili powder, cumin, garlic powder, onion powder, and smoked paprika.
3. Oil and season: Rub the pork all over with the oil, then coat it with the spice mixture, pressing gently so it sticks. The surface should have a light sheen, not a heavy layer of oil.
4. Arrange in the basket: Place the tenderloin in the air fryer basket or on the tray in a single layer with space around it for airflow. Most air fryers do not need preheating for this recipe. If yours is already preheated, start checking a little earlier.
5. Cook the first side: Air fry at 400°F (200°C) for about 10 minutes, until the top is browned and a light crust starts to form.
6. Flip and finish: Turn the tenderloin with tongs and continue cooking at 400°F (200°C) for about 8 to 12 minutes more. Start checking around 5 minutes after flipping. The pork is done when the thickest center reaches 145°F (63°C).
7. Glaze if using: For the honey-mustard version, brush the glaze on during the last 5 minutes so it turns glossy without burning too early.
8. Rest before slicing: Transfer the pork to a cutting board, tent loosely with foil, and rest for 5 to 10 minutes. Carryover heat may raise the temperature a couple of degrees.
9. Slice and serve: Cut across the grain into about 1/2-inch medallions. The center can still have a slight blush, and the slices should stay moist.

Air Fryer Time and Temperature for Pork Tenderloin

Cook pork tenderloin at 400°F (200°C) for about 18 to 22 minutes total, flipping once halfway through. I rely on the thermometer more than the clock here because air fryer models and tenderloin thickness vary.

Start checking the thickest part of the center a few minutes before you expect it to be done, especially if your air fryer runs hot or the tenderloin is on the smaller side. The outside should look browned with light crusting, and the final doneness cue is 145°F (63°C).

How to Keep Air Fryer Pork Tenderloin Juicy

This is mostly about shape, airflow, and not overshooting the temperature. I usually look for browned edges and a lightly crusted surface, then confirm with an instant-read thermometer.

• Pat the pork dry so the rub adheres and the outside browns better.
• Tuck the thin tail under if needed so it does not dry out before the center is done.
• Use only a light coating of oil.
• Rest the pork before slicing so the juices have time to settle.

Do You Need to Preheat the Air Fryer?

Usually no. For a whole pork tenderloin, I find the gentler start gives you a little more control before the outside browns too much, especially in basket-style air fryers.

If you use an oven-style air fryer, a brief preheat can help with browning. Just reduce the cooking time slightly and start checking early.

Air Fryer Pork Tenderloin Variations

Marinated Pork Tenderloin

For deeper flavor, marinate the tenderloin for 2 to 24 hours with oil, lime juice, and fajita or chili seasoning. Pat it very dry before air frying so the surface still browns well.

Honey Mustard Pork Tenderloin

Brush the Dijon, honey, and apple cider vinegar glaze on during the last 5 minutes of cooking. That gives the outside a sweet-tangy finish without letting the honey darken too soon.

Pork Tenderloin and Potatoes

For a one-basket meal, air fry halved baby potatoes with oil and salt at 400°F (200°C) for about 10 minutes first, then add the seasoned tenderloin and continue cooking until the pork reaches 145°F (63°C) and the potatoes are tender. Leave some space around the pork or the browning will be lighter.

What to Serve with Air Fryer Pork Tenderloin

• Roasted red potatoes or air-fried baby potatoes
• Mashed sweet potatoes
• Mediterranean cucumber salad
• Avocado salsa
• Caesar salad
• Warm tortillas and pico for a fajita-style plate

How to Store and Reheat Air Fryer Pork Tenderloin

Refrigerate leftovers in an airtight container for 3 to 4 days. For longer storage, freeze sliced pork in a freezer bag with as much air removed as possible for up to 3 months.

To reheat, warm slices in the air fryer at 300°F to 320°F (150°C to 160°C) for 3 to 5 minutes, just until heated through. Reheating slices works better than reheating the whole tenderloin, and if the pork seems dry, a few drops of broth can help.
