With just 1g net carb per serving and 48g of protein, pork tenderloin is one of the leanest, most protein-rich keto dinner options available.

Ingredients

• 2 pork tenderloins (about 450g each, total 900g)
• 2 tbsp olive oil
• 4 cloves garlic, minced
• 1 tsp dried rosemary
• 1 tsp dried thyme
• 1 tsp smoked paprika
• 1 tsp garlic powder
• 1/2 tsp onion powder
• 1 tsp salt
• 1/2 tsp black pepper
• 1 tbsp Dijon mustard

Instructions

1. Remove silver skin from pork tenderloins using a sharp knife by sliding it under the membrane and pulling away.
2. Mix olive oil, garlic, Dijon mustard, rosemary, thyme, smoked paprika, garlic powder, onion powder, salt, and pepper into a paste.
3. Rub the paste all over both tenderloins, coating evenly on all sides.
4. Marinate for at least 15 minutes at room temperature or up to 4 hours in the fridge.
5. Preheat air fryer to 400°F (200°C) for 3 minutes.
6. Place tenderloins in the air fryer basket. They may need to curve slightly to fit.
7. Air fry at 400°F for 20-22 minutes, turning halfway through, until internal temperature reaches 145°F (63°C) for slightly pink and juicy.
8. Rest for 5 minutes before slicing.
9. Slice into medallions and serve immediately.

Tips & Variations

• Always remove the silver skin; it is tough connective tissue that does not break down during cooking.
• Do not overcook pork tenderloin; it dries out quickly past 160°F. Aim for 145°F for the best texture.
• Stuff the tenderloin with spinach, feta, and sun-dried tomatoes for a special occasion presentation.
• Make a quick pan sauce by deglazing the air fryer drip tray with 2 tbsp chicken broth and 1 tbsp butter.
• Leftover slices are great cold in lettuce wraps or reheated in the air fryer at 350°F for 3-4 minutes.
