Why You’ll Love This Recipe
That Caramelized Crust Is Unreal – The brown sugar mixed with smoked paprika and chili powder creates this sweet and smoky crust that caramelizes beautifully in the air fryer. It gets all crispy and golden on the outside while the pork stays super juicy inside.
The Dijon Mustard Trick Is a Game Changer – Rubbing the tenderloin with Dijon mustard before adding the spice rub is not just for flavor. It acts like glue that helps the brown sugar spice mixture stick to the meat so you get an even, flavorful coating all around.

Sweet, Smoky, and a Little Spicy – The flavor combo here is seriously good. You get sweetness from the brown sugar, a nice smoky depth from the paprika, and a gentle kick from the chili powder. It all comes together without any one flavor taking over.
Pork Tenderloin Is a Lean and Affordable Cut – Pork tenderloin is one of the leanest cuts of pork you can buy, and it is usually pretty budget-friendly too. This recipe turns an affordable cut into something that looks and tastes like it came from a restaurant.
Ingredients
- 1 Pork Tenderloin (about 1.5 lb)
- 2 tbsp Brown Sugar
- 1 tsp Smoked Paprika
- 1 tsp Garlic Powder
- 1/2 tsp Onion Powder
- 1/2 tsp Chili Powder
- 1 tsp Salt
- 1/2 tsp Black Pepper
- 1 tbsp Olive Oil
- 1 tbsp Dijon Mustard
How to Make
Step 1
In a small bowl, mix together brown sugar, smoked paprika, garlic powder, onion powder, chili powder, salt, and pepper.
Step 2
Pat the pork tenderloin dry. Rub it all over with olive oil and dijon mustard, then coat generously on all sides with the brown sugar spice rub.

Step 3
Preheat the air fryer to 400°F (200°C). Place the pork tenderloin in the basket.

Step 4
Air fry for 18 to 22 minutes, flipping once halfway through, until the outside is deeply caramelized and the internal temperature reaches 145°F (63°C).
Step 5
Remove from the air fryer and let rest for 5 minutes. The juices will redistribute and the temperature will rise a few more degrees.
Step 6
Slice into 1/2-inch thick medallions and serve.

Tips
Pat the Pork Completely Dry
Before you rub anything on the tenderloin, use paper towels and really press down on the meat to get as much moisture off the surface as possible. If the outside is wet, the spice rub won’t stick properly and you won’t get that caramelized crust you’re going for.

Don’t just give it a quick dab. Use two or three paper towels and pat every side of the tenderloin until it feels dry to the touch.
This one step makes a huge difference in how the outside turns out in the air fryer. Dry surface equals better browning and a crispier bark on the outside.
Trim the Silver Skin First
Pork tenderloin usually comes with a thin, silvery membrane on one side called silver skin. If you leave it on, it won’t break down during cooking and you’ll end up with chewy, rubbery bites mixed in with your tender pork.

To remove it, slide a sharp knife under one end of the membrane and gently pull it away while angling the blade slightly upward. It should come off in one or two strips without taking much meat with it.
If your tenderloin also has a thicker strip of fat or a small flap of meat hanging off, trim that too so it cooks evenly all the way around.
Don’t Skip the Dijon Mustard
The mustard isn’t there for flavor as much as it’s there to act like glue. When you rub the olive oil and Dijon on the pork first, it creates a sticky base layer that the brown sugar spice rub clings to really well.
Without it, the rub tends to fall off during cooking or when you flip the tenderloin halfway through. You won’t taste a strong mustard flavor in the finished pork – it mellows out completely and just blends into the background.

Frequently Asked Questions
How do I know when the pork tenderloin is done?
The most reliable way is to use an instant-read meat thermometer. You want the thickest part of the tenderloin to reach 145°F before you take it out of the air fryer.
After it rests for about 5 minutes, the temperature will climb a few more degrees on its own. If you cut into it, the inside should look slightly pink in the center – that’s perfectly safe and means it’s juicy and not overcooked.
