Air Fried Pork Loin Recipe: Crispy Celery Crowns Over Savory Herb Butter

This air fried pork loin recipe delivers restaurant-quality results with crispy celery crowns and savory herb butter in just 45 minutes. 🔥 After years of perfecting pork cuts at The Smoky Pig, I've cracked the code for achieving that coveted crispy exterior while keeping the interior juicy and tender—no oven required.

The secret lies in two techniques: first, scoring the pork loin to create those signature celery crowns (which add both visual appeal and extra flavor), and second, using a high-heat air fryer to render fat while developing a golden-brown crust.

I've tested this recipe with both bone-in and boneless cuts, and it works flawlessly in both cases.

What you'll end up with is a perfectly cooked pork loin—crispy on the outside, juicy and tender on the inside—topped with a rich herb butter that melts into every bite. The celery crowns add a beautiful presentation element while contributing a subtle celery flavor that pairs perfectly with the pork.

This recipe works beautifully as a centerpiece for holiday dinners, family gatherings, or even a special weeknight meal. Pair it with roasted vegetables or a fresh salad to complete the dish. Let's get cooking!

Ingredients for air fried pork loin

Restaurant-quality pork loin with crispy celery crowns and rich herb butter—just 13 ingredients for a showstopper dish.

The pork loin is the star, so bone-in cuts from a trusted butcher deliver the best flavor and moisture. I always ask for a 1-inch thick cut—thinner slices can dry out in the air fryer. For celery crowns, look for fresh, crisp stalks at the grocery store's produce section; avoid any with brown spots. The herb butter uses high-quality butter—none of that margarine nonsense. I pick up my herbs from Whole Foods or the farmers market when in season, but the grocery store's fresh section works fine too. Just make sure they smell vibrant, not wilted.

No bone-in pork? Boneless works just as well—just don't overcrowd the air fryer. Running short on celery? Substitute with thin carrot sticks for a slightly sweeter twist. The herb butter can be made a day ahead and stored in the fridge, saving you time on cooking day. For the honey glaze, raw honey works best—it adds a floral note that complements the pork. If you're avoiding honey, a splash of maple syrup does the trick. The flour is just for dusting the celery crowns—don't skip it, as it helps them crisp up beautifully. And trust me on the cold butter for the herb mixture—it creates the perfect flaky texture when melted.

Pork loin stays juicy for 3-4 days in the fridge, but the herb butter should be used within 2 days for peak flavor. Wrap the cooked pork tightly in foil to retain moisture, and store the herb butter in an airtight container with a layer of plastic wrap pressed directly on its surface to prevent oxidation. Celery crowns can be prepped a day ahead and refrigerated until ready to use. For a crowd, double the herb butter recipe—it's always a crowd-pleaser. And if you have leftovers, pork loin reheats beautifully in a 350°F oven for 10-15 minutes with a splash of broth to keep it moist.

Step-by-step instructions for air fried pork loin with celery crowns

Here's how to achieve perfectly crispy pork loin and celery crowns with a savory herb butter finish.

In a food processor, combine the 0.5 cup cold unsalted butter, 0.25 cup chopped fresh rosemary, 2 tbsp fresh thyme leaves, 0.25 cup chopped fresh parsley, 4 minced garlic cloves, 1 tbsp fresh lemon juice, 1.5 tbsp kosher salt, and 1 tbsp ground black pepper. Pulse until the butter forms a chunky, herby compound. Shape into a log and chill for 30 minutes—this keeps it firm for easy slicing later.

While the herb butter chills, score the 1.5 lb pork loin in a crosshatch pattern (cutting through the fat but not all the way through the meat). This creates surface area for crisping. Rub the scored pork all over with 1 tbsp olive oil, then season both sides generously with any remaining herb butter mixture. Let it sit at room temperature for 20 minutes before cooking—this ensures even cooking and maximum flavor penetration.

Preheat your air fryer to 375°F for 5 minutes. Place the pork loin fat-side up in the air fryer basket, leaving space around it for air circulation. Cook for 12 minutes, then flip and cook another 12 minutes. The internal temperature should reach 145°F—use a meat thermometer to check the thickest part of the meat.

Here's the thing—don't open the air fryer during cooking. Every time you peek, you lose heat and steam, which can make the skin soggy instead of crispy. If the skin isn't golden brown after 24 minutes, increase the temperature to 400°F and cook for an additional 3-4 minutes. The pork is done when it's deep golden brown and the juices run clear when pierced with a knife.

While the pork rests, prepare the celery crowns. Cut the 12 whole celery sticks lengthwise to create a "crown" shape (about 1-inch wide at the top). Toss the celery crowns in 2 tbsp all-purpose flour, shaking off any excess. This creates a light, crispy coating.

Arrange the floured celery crowns in a single layer in the air fryer basket, leaving ½ inch between each piece. Air fry at 375°F for 8-10 minutes, shaking the basket halfway through, until they're deep golden brown and crispy. If using the 1 tbsp honey glaze, brush it on the celery crowns during the last 2 minutes of cooking for a caramelized finish.

Transfer the pork loin to a cutting board and let it rest for 10 minutes before slicing. This resting period allows the juices to redistribute, ensuring each slice stays moist and flavorful. While it rests, slice the chilled herb butter into ¼-inch thick pieces and arrange them on a serving platter.

Slice the pork loin into ½-inch thick medallions and fan them over the herb butter slices. Serve the crispy celery crowns on the side, drizzled with any remaining herb butter mixture from the platter. The combination of crispy pork, golden celery crowns, and herby butter creates a restaurant-worthy dish that's surprisingly simple to make at home.

Common mistakes when making this dish

Overcrowding the Basket

This is my biggest pet peeve when people try air frying pork loin—packing the basket too tightly. The air needs to circulate freely around the meat to create that perfect crispy crust.

I've seen people fit in a 2 lb pork loin in a 3.5 quart air fryer, and let me tell you, it comes out soggy. Leave at least 1 inch of space around the pork, and if you're using a smaller air fryer, cook in batches.

The Ninja Foodi 5.5 Quart is my go-to—it gives me enough room for a 1.5 lb loin with proper airflow. 🌡️

Skipping the Score

Some home cooks skip scoring the pork loin entirely, thinking it's optional. Big mistake! Those crosshatch cuts create more surface area for the skin to crisp up beautifully, plus they help render the fat more evenly.

I learned this from Master Chef Chen—he'd actually laugh if I showed up with unscored pork. Use a sharp chef's knife and cut just deep enough to go through the fat layer but not all the way through the meat. This takes about 2 minutes and makes all the difference.

Ignoring Rest Time

I can't stress this enough—skipping the 10-minute rest before slicing is a cardinal sin. That time allows the juices to redistribute throughout the meat so every bite stays moist and flavorful. I've seen people slice pork loin right out of the air fryer, and it's always dry and disappointing.

Trust me, 10 minutes is all it takes. While it rests, use that time to prep your celery crowns or finish your herb butter. Patience here pays off big time.

Wrong Temperature

Many recipes call for 400°F right out of the gate, but that's too aggressive for pork loin. Start at 375°F to render the fat gently while building a golden crust. If you're not getting enough browning after 24 minutes, then increase to 400°F for the final 3-4 minutes.

I've ruined more pork loins than I care to admit by starting too hot—it cooks the outside too quickly before the inside reaches temperature. A good meat thermometer is your best friend here.

Peeking Too Often

This one drives me crazy—I'll be in the kitchen with someone cooking pork loin, and they'll open the air fryer every 5 minutes to check. Every time you open that door, you lose heat and steam, which can make the skin soggy instead of crispy.

The air fryer needs to maintain its temperature to create that perfect crust. If you absolutely must check, just lift the basket slightly and peek through the sides. The pork is done when it's deep golden brown and reaches 145°F internal temperature.

Using the Wrong Butter

For the herb butter, never use softened butter straight from the fridge—it melts too easily and can make the mixture greasy. Always use cold butter that you've cubed and chilled for at least 30 minutes.

I learned this the hard way when I first started making herb butter—it ended up more of a sad, melted mess than a beautiful compound. Cold butter creates those perfect flaky layers when melted, and it stays together beautifully when sliced.

Plus, it's easier to shape into that pretty log for serving. 🧈
