Instructions

  1. Step 1: Preheat your air fryer to 400°F for 5 minutes. Meanwhile, rub 1.5 lbs pork tenderloin evenly with 1 tbsp olive oil and 2 tbsp Cajun seasoning, 1 tsp garlic powder, 1 tsp smoked paprika, 1 1/2 tsp salt, and 1 tsp black pepper.
  2. Step 2: Toss 2 medium peeled and cut sweet potatoes wedges with 2 tbsp olive oil and a pinch of salt and pepper in a bowl until evenly coated.
  3. Step 3: Place the pork tenderloin in the air fryer basket and cook at 400°F for 20 minutes, flipping halfway through, until an internal temperature of 145°F is reached.
  4. Step 4: After 5 minutes of pork cooking, add the sweet potato wedges in an even layer around the pork or in a separate basket if available. Cook both pork and wedges together for the remaining time, shaking sweet potato wedges once halfway to ensure crispiness.
  5. Step 5: Remove pork tenderloin and let rest for 5 minutes before slicing into 1/2-inch medallions. Serve with sweet potato wedges and garnish with 1 tbsp fresh chopped thyme if using.
