Air Fryer Pork Tenderloin with Mustard Glaze

Pork tenderloin is a lean, quick-cooking cut that works especially well in the air fryer, where strong heat helps the outside take on colour while the centre stays tender. Here it is finished with a Dijon, honey and cider vinegar glaze, sharpened with garlic and rounded out by smoked paprika for gentle warmth. The result is glossy, savoury-sweet pork with a clean tang rather than a heavy sauce. Cooking to 63°C (145°F) and allowing a short rest are key to keeping the slices juicy. Serve it as an easy dinner centrepiece with potatoes, grains, salad or roasted vegetables.

Why this recipe works

  • Fast cooking: Pork tenderloin is naturally lean and narrow, so it cooks quickly in the air fryer without a long oven roast.
  • Balanced glaze: Dijon mustard and cider vinegar sharpen the honey, keeping the glaze bright rather than overly sweet.
  • Big flavour, few ingredients: Garlic, smoked paprika and mustard give the pork a savoury, aromatic coating with very little prep.

Timing notes

  • Rest before slicing: Let the tenderloin rest for 5 minutes so the juices settle and the final texture stays moist.
  • Best served soon after cooking: Slice just before serving and brush with the warmed reserved glaze for the glossiest finish.

Texture tips

  • Use a thermometer: Pull the pork when the thickest part reaches 63°C (145°F); the temperature will rise slightly as it rests.
  • Account for tapered ends: If one end is much thinner, fold it underneath before cooking so the tenderloin cooks more evenly.

Ingredient notes

  • Choose tenderloin, not loin: Pork tenderloin is a small, lean cut that suits quick air-frying; pork loin is larger and needs a different cooking time.
  • Trim the silverskin: Removing silverskin before seasoning prevents tough, chewy patches after cooking.
  • Adjust the tang: White wine vinegar gives a cleaner, sharper finish, while apple cider vinegar keeps the glaze rounder and fruitier.

Make-ahead tips

  • Mix the glaze ahead: The mustard glaze can be mixed in advance and kept chilled, then brushed on just before cooking.
  • Reheat gently: Warm leftovers at 160°C (320°F) in the air fryer or in a saucepan with a splash of water to avoid drying out the slices.
  • Freeze sliced leftovers: Freeze well-wrapped cooked slices, then defrost overnight in the fridge before reheating gently.

  1. Pat the pork dry and trim away any silverskin. Season all over with the salt, pepper and smoked paprika, then rub with the olive oil.
  2. In a small bowl, mix the Dijon mustard, honey and apple cider vinegar. Finely grate or crush the garlic and stir it in, then spoon out about one-third of the glaze into a separate bowl for finishing later.
  3. Brush the larger portion of glaze over the pork. Air-fry at 200°C (390°F) for 12 to 16 minutes, turning and brushing once halfway, until the thickest part reaches 63°C (145°F).
  4. Transfer the pork to a board and rest for 5 minutes. The temperature will rise slightly as it rests and the juices will settle.
  5. Tip the reserved glaze into a small saucepan and warm over a low heat for 1 to 2 minutes, just until glossy and slightly thickened; do not let it boil hard. Slice the pork and brush with the warm glaze to serve.

Recipe notes

Tips

  • For the juiciest result, use a thermometer and pull the pork at 63°C (145°F), then rest it so it finishes cooking gently.
  • If your tenderloin is thin at one end, fold that end under and secure with a cocktail stick so it cooks more evenly; remove before slicing.

Substitutions

  • Replace Dijon mustard with whole-grain mustard for a milder heat and a more textured glaze.
  • Replace apple cider vinegar with white wine vinegar for a cleaner, sharper tang.

Storage

  • Refrigerate up to 3 days
  • Cool leftovers quickly, then refrigerate in a sealed container for up to 3 days. Reheat slices gently in the air fryer at 160°C (320°F) for 3 to 5 minutes or in a saucepan with a splash of water until piping hot; avoid overcooking. Freeze sliced pork well wrapped for up to 2 months and defrost overnight in the fridge before reheating.
