Maple Mustard Air Fryer Pork Tenderloin

Maple Mustard Air Fryer Pork Tenderloin

What I like about this air fryer pork tenderloin method is that the maple mustard glaze goes on near the end, where it can caramelize instead of scorching. I rely on the thermometer more than the clock here because pork tenderloin cooks fast and air fryer models vary.

This version keeps the seasoning straightforward and gives you a browned, smoky exterior with a sweet-tangy finish. The main things that matter are drying the pork well, leaving space around it in the basket, and pulling it just before it reaches final temperature so it can rest to juicy slices.

Ingredients for Maple Mustard Air Fryer Pork Tenderloin

• 1 pork tenderloin, 1 to 1 1/4 pounds (about 575g)
• 1 tablespoon olive oil
• 1 teaspoon smoked paprika
• 1 teaspoon garlic powder
• 1 teaspoon onion powder
• 1 teaspoon kosher salt
• 1/2 teaspoon black pepper
• 1 tablespoon brown sugar
• 2 tablespoons Dijon mustard
• 1 tablespoon whole-grain mustard
• 2 tablespoons maple syrup

Spice note: For a simple dry rub like this, fine spices from Selefina coat the pork more evenly, which helps the surface brown without clumping in spots.

If you want a deeper glaze, stir in 1 teaspoon Worcestershire sauce. For a sharper finish, use 1 teaspoon balsamic vinegar instead. If the glaze feels too thick to brush, loosen it with 1 to 2 teaspoons water.

An optional brine can add extra seasoning, but keep it short, about 30 minutes to 4 hours. If you brine, rinse and pat the pork very dry, then reduce the salt in the rub so the finished pork does not taste too salty.

How to Make Maple Mustard Pork Tenderloin in the Air Fryer

1. Prep the pork: Pat the tenderloin dry with paper towels and trim off any silver skin if needed. If you brined it first, rinse well and dry it thoroughly so the oil and rub will stick.
2. Mix the rub: In a small bowl, combine the smoked paprika, garlic powder, onion powder, kosher salt, black pepper, and brown sugar.
3. Mix the glaze: In a second bowl, stir together the Dijon mustard, whole-grain mustard, and maple syrup until smooth enough to brush. Add Worcestershire, balsamic, or a little water only if you want to adjust the flavor or texture.
4. Season the tenderloin: Rub the pork all over with the olive oil, then coat it evenly with the spice mixture. Press the rub onto the surface so it adheres well.
5. Preheat if your air fryer benefits from it: Preheat to 380°F to 400°F (193°C to 200°C) for 3 to 5 minutes if your model browns better with a hot start.
6. Air fry: Place the tenderloin in the basket in a single layer with space around it. Air fry at 380°F to 400°F (193°C to 200°C) for 18 to 24 minutes total, flipping once halfway through. If your air fryer has hot spots, rotate the tenderloin when you flip it.
7. Glaze near the end: When the thickest part reaches about 140°F to 142°F (60°C to 61°C), brush on a light layer of glaze. Return it to the air fryer for 2 to 4 minutes, just until the glaze looks glossy and lightly caramelized. Watch closely here because maple syrup can darken fast.
8. Rest: Transfer the pork to a cutting board and let it rest for 5 to 10 minutes. It should rise to about 145°F (63°C) as it rests.
9. Slice and serve: Slice across the grain into medallions and spoon over any extra glaze if you like.

Air Fryer Time and Temperature for Pork Tenderloin

A good starting point is 380°F to 400°F (193°C to 200°C) for 18 to 24 minutes, flipping once. Start checking on the early side if your tenderloin is smaller or your air fryer runs hot.

I usually look for a browned outside with the rub set on the surface, then check the thickest part with an instant-read thermometer. Pulling the pork at 140°F to 142°F (60°C to 61°C) and resting it to 145°F (63°C) gives you a better shot at juicy slices than taking it all the way to final temperature in the basket.

How to Keep Air Fryer Pork Tenderloin Juicy

This is where the texture can go wrong: pork tenderloin is lean, so it dries out quickly if it stays in the air fryer too long. The oil helps the rub cling and supports browning, but you do not need a heavy coating.

The other part that matters is basket space. If the tenderloin is crowded, the exterior does not brown as well, and if your basket is small, it is better to cook one at a time.

Why the Maple Mustard Glaze Goes on at the End

The glaze is better brushed on after most of the cooking is done. Maple syrup adds color and sweetness, but it can burn early in a hot air fryer.

The part I pay attention to is the edge of the glaze. It should look glossy and a little darker around the edges, not blackened.

How to Store and Reheat Maple Mustard Air Fryer Pork Tenderloin

Store leftover pork in an airtight container in the refrigerator for up to 3 to 4 days. If you have extra glaze, keeping it separate helps the sliced pork stay less sticky in storage.

To reheat, warm the pork slices in the air fryer at a lower temperature until just heated through, checking often. Short reheating bursts work better than one long cycle, which can dry the pork out.

You can also mix the rub and glaze ahead of time. If you are using the optional brine, that can be done in advance as well.
