The pork sirloin roast is the star—look for well-marbled cuts at Whole Foods or Costco (avoid anything grayish). A 2-pound roast serves 4 with leftovers. The herb rub relies on fresh rosemary and thyme, so grab bunches from the produce section (dried won’t give the same punch). I always pick up Diamond Crystal kosher salt—it sticks better to the meat and has a cleaner flavor than iodized.

No fresh herbs? Dried at one-third the amount works in a pinch, but fresh is worth the effort. Out of Dijon? Whole-grain mustard adds a nice texture. Brown sugar can be swapped for maple syrup (use 1.5 tbsp for the same sweetness). If you’re missing smoked paprika, regular paprika plus a pinch of cayenne gets you close. The apple cider vinegar can be subbed with lemon juice (same amount).

The roast keeps 3-4 days in the fridge—great for sandwiches. Freeze leftovers for up to 3 months (slice before freezing for easy portions). Bring pork to room temp before cooking (about 30 minutes on the counter).

Step-by-Step Instructions for Pork Sirloin Roast in Air Fryer

Here’s how I achieve that perfect herb-crusted exterior with a juicy center every time.

Step 1: Create the Herb Rub and Prep the Pork

In a small bowl, combine the 2 tbsp fresh rosemary, 2 tsp fresh thyme, 1 tbsp Dijon mustard, 1 tbsp brown sugar, 1 tsp smoked paprika, 1 tsp dried oregano, 1.5 tsp kosher salt, and 1 tsp freshly ground black pepper. This blend delivers layers of flavor that will penetrate the meat beautifully.

Pat the 2 lb pork sirloin roast dry with paper towels—this ensures the rub adheres and promotes even browning. Rub the herb mixture all over the pork, pressing firmly to create a thick crust. The mustard acts as a binder, while the sugar will caramelize during cooking.

Step 2: Sear the Pork in the Air Fryer

Preheat your air fryer to 400°F for 5 minutes. While it heats, mince the 4 cloves garlic cloves and mix with the 2 tbsp olive oil and 1 tbsp apple cider vinegar. Drizzle this mixture over the seasoned pork, ensuring it’s fully coated.

Place the pork in the air fryer basket fat-side up. Air fry at 400°F for 10 minutes to create a beautiful sear on the exterior. This high-heat step locks in juices and jumps starts the caramelization process. Don’t skip this—it’s what gives the roast that deep, savory crust.

Step 3: Cook Low and Slow for Tenderness

Reduce the air fryer temperature to 300°F and continue cooking for 30-40 minutes, flipping the pork halfway through. You’re aiming for an internal temperature of 145°F—use a meat thermometer to check the thickest part. The lower temperature allows the pork to cook evenly without drying out.

This is where the magic happens. The herb rub forms a flavorful crust while the vinegar and mustard work together to keep the meat moist. If the exterior starts to darken too quickly, tent the pork loosely with foil to prevent over-browning.

Step 4: Rest and Slice for Maximum Juiciness

Once the pork reaches temperature, transfer it to a cutting board and let it rest for 10-15 minutes. This resting period allows the juices to redistribute throughout the meat, ensuring every slice is moist and flavorful. Tent it loosely with foil to keep it warm.

Slice the pork against the grain into ½-inch thick pieces. The grain runs parallel to the long side of the roast, so cut perpendicular to that direction. Serving it immediately while warm guarantees the juiciest results, with the herb crust providing a perfect contrast to the tender interior.

Regional Styles of This Recipe

Southern Style

In the South, we add a touch of Cajun seasoning to the rub for a spicy kick. I mix 1 tsp Tony Chachere’s with the herbs and mustard. The heat from the cayenne and black pepper in the blend pairs perfectly with the pork’s richness. 🌶️

Asian Fusion

For an Asian twist, swap the rosemary and thyme for 2 tbsp grated ginger and 3 minced garlic cloves. Add 2 tbsp soy sauce and 1 tbsp honey to the olive oil mixture. This creates a sweet-savory glaze as it cooks.

Mediterranean Approach

Inspired by Greek flavors, I combine 1 tbsp dried oregano, 1 tsp lemon zest, and 3 minced garlic cloves with the olive oil. The bright citrus notes cut through the pork’s richness beautifully.

Latin American

Use 1 tbsp ground cumin, 1 tsp chili powder, and 1 tbsp lime juice in place of the vinegar. This gives the roast a warm, earthy profile with a hint of tang. Perfect for tacos or rice bowls.

I often serve this version with avocado slices and lime wedges. 🌟

German Tradition

For a classic German flavor, I add 1 tbsp caraway seeds and 1 tsp juniper berries (crushed) to the rub. The caraway adds a distinct warmth that’s traditional in German pork dishes.
