Air Fryer Pork Tenderloin

My air fryer pork tenderloin is marinated in a Dijon mustard-glazed oil and cooked to tender, juicy perfection. I make this recipe when I want a quick, healthy meal that still feels special!

My Easy Way to Make Pork Tenderloin in the Air Fryer

I first tried air fryer pork tenderloin one weekend when my husband Ben, and I were hosting a casual family dinner. I wanted something that felt like a centerpiece, but I didn’t want to be stuck in the kitchen the whole time our guests were over.

In the past, I would have roasted the pork low and slow or grilled it. Roasting turns out delicious but requires me to babysit the oven, and grilling can go from underdone to overcooked in a matter of minutes. Plus, it was gross and rainy outside.

Instead, I threw together a quick marinade and left the pork for about an hour, then let my air fryer work its magic. My in-laws were so impressed, they assumed I’d spent all day on the meal and couldn’t figure out where I’d found the time. They were amazed when I told them I just used the air fryer!

Now I make my air fryer pork tenderloin recipe all the time, especially for nights when I want an easy meal that feels a little more special. It’s one of those Sunday dinners that even my kids love.

What to look for when selecting pork tenderloin at the grocery store

I always choose a pork tenderloin that’s evenly shaped and doesn’t have the silver skin or large pieces of excess fat, since those can make the meat cook unevenly. If the butcher hasn’t removed the silver skin or fat, I trim before marinating the pork tenderloin.

It’s important not to confuse pork tenderloin with pork loin. Tenderloin is a smaller, leaner cut that cooks quickly, while pork loin is much larger and takes more time to cook properly. I stick with tenderloin for this recipe because it turns out juicy and tender in the air fryer.

Air Fry Pork Tenderloin Ingredients

• Pork tenderloin – This lean cut stays juicy when marinated and air fried, and it’s nice that it cooks quickly compared to larger roasts.
• Olive oil – This helps keep the meat moist and adds a subtle richness to the marinade.
• Soy sauce – I love how soy sauce adds both saltiness and depth. It infuses the pork with so much flavor!
• Garlic – Freshly minced is my preference to bring a punch of savory flavor. Jarred also works or even garlic powder in a pinch.
• Brown sugar – The sweetness balances the saltiness of the soy sauce and helps create a caramelized crust on the outside.
• Dijon mustard – I love how Dijon adds tang and a hint of sharpness to round out the flavors.
• Salt and black pepper – These classics enhance the pork’s natural flavor and balance the marinade.

STEP ONE: Mix the olive oil, soy sauce, garlic, brown sugar, Dijon mustard, and salt and pepper in a bowl.

STEP TWO: Add the marinade and pork tenderloin to a plastic Ziploc bag, making sure the marinade is on the entire tenderloin. Let it marinate in the fridge for at least 30 minutes, but up to 5 days.

STEP THREE: Preheat the air fryer to 400 degrees.

STEP FOUR: Remove the pork tenderloin from the marinade and carefully place it in the air fryer basket or air fryer oven.

STEP FIVE: Air fry it for 22 to 25 minutes, flipping it halfway through the cooking time. It is done cooking when the thickest part reads at least 145 degrees with a meat thermometer.

STEP SIX: Let the meat rest for 5-10 minutes before slicing and serving.

Tips for the Best Air Fryer Pork Tenderloin

• Marinate the pork tenderloin for at least 30 minutes for great flavor, but I like to let it sit in the fridge overnight or even several days if I can plan ahead.
• Trim and remove any silver skin before marinating. This is my trick to making sure the pork cooks evenly and stays tender.
• I pat the pork dry before cooking. Removing excess moisture helps it sear and develop a nice crust.
• Once the pork tenderloin reaches 145 degrees F, I remove it from the air fryer. I use an instant-read thermometer to make sure it’s cooked perfectly.
• I let the meat rest for at least 5 minutes before slicing so the juices don’t run out onto the cutting board.

Air Fried Pork Tenderloin Variations and Substitutions

• If I have zero time to marinate, I’ll let the pork sit in half of the mixture while the air fryer preheats, then baste the tenderloin with the rest of the mixture after cooking.
• I sometimes swap the marinade for a dry rub with spices like chili powder, smoked paprika, garlic powder, onion powder, salt, and pepper.
• For a tangy, slightly sweet flavor, I’ll make a balsamic marinade instead.
• I like to add crushed red pepper flakes to the marinade for a hint of heat.
• Use maple syrup instead of brown sugar for a deeper, richer sweetness. This is my go-to in the fall when I’m craving autumn flavors!
