Ingredients for air fry pork loin
Simple seasonings elevate pork loin to crispy, tender perfection in the air fryer.
| Ingredient | Amount | Notes |
|---|---|---|
| Pork Loin 🥩 | 2 lb | Boneless, trimmed of excess fat |
| Kosher Salt 🧂 | 1 ½ tsp | Diamond Crystal preferred for even seasoning |
| Freshly Ground Black Pepper 🌶️ | 1 tsp | Coarse grind for texture |
| Garlic Powder 🧄 | 1 tsp | Not garlic salt for pure flavor |
| Onion Powder 🧅 | 1 tsp | Enhances savory depth |
| Dried Rosemary 🌿 | 1 tsp | Crushed to release aroma |
| Dried Thyme 🍃 | 1 tsp | Complements pork naturally |
| Smoked Paprika 🌶️ | ½ tsp | Adds subtle smokiness |
| Olive Oil 🫒 | 1 tbsp | Extra-virgin for richness |
| Dijon Mustard 🟡 | 1 tbsp | Creates flavorful crust |
| Apple Cider Vinegar 🍏 | ½ tbsp | Balances seasoning blend |
| Brown Sugar 🟤 | 1 tbsp | Light or dark for caramelization |
The pork loin quality is non-negotiable. Look for well-marbled, boneless cuts at Whole Foods or Costco—avoid anything labeled 'enhanced' or pre-brined. Diamond Crystal kosher salt is my go-to for its clean flavor and even distribution. The herbs should be fresh enough to release their aroma when crushed between your fingers; if they smell like dust, replace them.
No smoked paprika? Regular paprika with a pinch of cayenne can mimic the depth. Dijon mustard is key for that sticky, golden crust, but whole-grain mustard adds pleasant texture. Apple cider vinegar can be swapped with red wine vinegar if that's what you have. The brown sugar helps caramelization—honey or maple syrup at half the amount works too, though it may darken faster.
Store uncooked pork in the fridge for up to 3 days, or freeze for 6 months. The seasoning blend keeps indefinitely in a cool, dark place. Cooked leftovers stay fresh for 4-5 days and reheat beautifully in the air fryer for 3-4 minutes at 350°F.

Step-by-step instructions for air fry pork loin
Master the technique that guarantees perfectly cooked pork with a flavorful crust every time.
Create the Dry Rub and Season the Loin
In a small bowl, combine the 1.5 tsp Kosher Salt, 1 tsp Freshly Ground Black Pepper, 1 tsp Garlic Powder, 1 tsp Onion Powder, 1 tsp Dried Rosemary, 1 tsp Dried Thyme, and 0.5 tsp Smoked Paprika. Crush the dried herbs between your fingers to release their aromatic oils.
Pat the 2 lb Pork Loin thoroughly dry with paper towels—this ensures the seasoning adheres properly and promotes even browning. Rub the spice mixture all over the pork, pressing firmly to create a uniform coating. Let it sit at room temperature for 15-20 minutes while you prepare the air fryer.
Prepare the Flavorful Glaze
In a separate bowl, whisk together the 1 tbsp Olive Oil, 1 tbsp Dijon Mustard, 0.5 tbsp Apple Cider Vinegar, and 1 tbsp Brown Sugar until fully emulsified. The acidity from the vinegar balances the richness of the pork, while the brown sugar will caramelize beautifully in the air fryer.
Brush this glaze evenly over the seasoned pork loin, making sure to coat all sides. The glaze should form a thin, sticky layer that will transform into a deep golden crust during cooking. Any excess glaze can be reserved for basting later if desired.
Air Fry to Perfection
Preheat your air fryer to 375°F for 5 minutes. Place the glazed pork loin in the air fryer basket, ensuring it's not touching the sides. Cook for 25 minutes, then flip the loin using tongs—this ensures even cooking and consistent browning on all sides.
Continue cooking for an additional 20-25 minutes until the internal temperature reaches 145°F on an instant-read thermometer. The exterior should be a deep golden brown with slight caramelization from the sugar in the glaze. If you notice any spots browning too quickly, tent them loosely with foil.
Rest and Slice for Maximum Tenderness
Transfer the cooked pork loin to a cutting board and tent loosely with foil. Let it rest for 10-15 minutes—this crucial step allows the juices to redistribute throughout the meat, ensuring every slice remains moist and tender.
After resting, slice the pork loin against the grain into ½-inch thick medallions. Each slice should reveal a juicy interior with a perfectly caramelized exterior. The meat should pull apart slightly with a gentle tug, indicating ideal doneness. Serve immediately while still warm for the best texture.
Pro Tips For Making Air Fry Pork Loin
- Preheat the Air Fryer: I learned this the hard way—cold starts lead to uneven cooking. Give it a full 5 minutes at 375°F before adding the pork loin.
- Pat It Dry: Sounds weird, but it works: dry the pork loin thoroughly with paper towels before seasoning to guarantee a better crust.
- Don’t Overcrowd: After burning three batches, I finally figured out that leaving space around the pork loin lets the air circulate properly.
- Rest Before Slicing: Give it a solid 5-10 minutes under foil after cooking—your future self will thank you when the juices stay in the meat.
Dietary considerations for this recipe
Gluten-Free & Naturally Safe
This air fry pork loin is inherently gluten-free as written. All seasonings and glaze ingredients contain no wheat or gluten derivatives. Just double-check your Dijon mustard brand—some add wheat-based thickeners. I trust Maille or Grey Poupon for consistent quality. 💡
Low-Carb & Keto Friendly
With only 1 tbsp brown sugar in the glaze for the entire 2 lb loin, each serving has minimal carbs. For strict keto, swap the brown sugar for 1 tsp erythritol or skip it entirely—the herbs and mustard provide plenty of flavor.
Dairy-Free By Design
No dairy appears in this recipe, making it safe for lactose intolerant cooks. The olive oil and Dijon mustard create a rich crust without butter or cream. Even the resting step uses foil, not dairy-based basting liquids.
Allergen Awareness
Primary allergens come from mustard in the glaze. For mustard allergies, replace Dijon mustard with 1 tbsp olive oil + ½ tsp lemon juice for acidity. The pork itself and all dry spices are allergen-free.
Sodium Considerations
With 1.5 tsp kosher salt for 2 lbs pork, this recipe is moderately seasoned. For low-sodium needs, reduce salt to ½ tsp and boost herbs. The Dijon mustard adds minimal additional sodium.
Paleo Adaptation
Make it paleo by replacing brown sugar with 1 tbsp raw honey or maple syrup. Ensure your Dijon mustard contains no additives—Primal Kitchen makes a clean version. All other ingredients fit paleo guidelines perfectly. 🌿

Frequently asked questions
What temperature should I use for air frying pork loin?
Preheat to 375°F for even cooking. This creates a crispy exterior while keeping the inside juicy. Always verify doneness with a meat thermometer for best results.
How long does pork loin take in an air fryer?
Cook a 2 lb loin for 45-50 minutes total, flipping halfway. The exact time depends on thickness, so check internal temperature reaches 145°F.
Can I use a pork tenderloin instead?
Yes, but reduce cook time to 20-25 minutes at 375°F. Tenderloin is smaller and cooks faster. Watch closely to avoid overcooking this leaner cut.
Why did my pork loin turn out dry?
Overcooking is the main culprit. Always use a thermometer and pull at 145°F. Letting it rest 10-15 minutes after cooking helps retain moisture.
