A frenched rack of lamb coated in a Dijon herb crust and air fried to a golden-brown exterior with a rosy pink medium-rare interior. Ready in about 20 minutes of cook time, it makes an impressive holiday main course.

Ingredients

Scale
  • 1 rack of lamb (about 1.5 lbs, frenched)
  • 3 tbsp Dijon mustard
  • 3 garlic cloves, minced or grated
  • 1 tbsp fresh rosemary, finely chopped
  • 1 tbsp fresh thyme leaves
  • 2 tbsp olive oil
  • 1/2 cup panko breadcrumbs (optional, for a crust)
  • Salt and black pepper

Instructions

  1. Pat the rack of lamb dry with paper towels. Season generously all over with salt and black pepper. Let it sit at room temperature for 30 minutes so it cooks evenly.
  2. Mix together the Dijon mustard, minced garlic, rosemary, thyme, and olive oil into a paste. Spread generously over the fat side and meaty sections of the rack. If using a breadcrumb crust, press the panko firmly into the mustard coating so it adheres.
  3. Preheat your air fryer to 400°F for 4 minutes.
  4. Place the rack of lamb fat-side up in the basket, curving it slightly if needed to fit. Air fry at 400°F for 20 minutes for medium-rare (internal temp 125–130°F), or 24 minutes for medium (135°F).
  5. Check the internal temperature with an instant-read thermometer in the thickest part of the meat, away from the bone.
  6. Remove from the air fryer and tent loosely with foil. Rest for 8 minutes before carving — the temperature will rise another 3–5°F during resting.
  7. To carve, hold the bones and slice between each rib for individual chops.

Notes

Doneness guide: Rare 120–125°F; Medium-rare 125–130°F (ideal — deeply flavorful and tender); Medium 130–140°F; Well-done 155°F+ (not recommended).

Extra crust: For a more pronounced sear, increase temperature to 420°F for the last 3–4 minutes once the internal temp is near your target.

Larger racks: Add 3–5 minutes per extra half pound and always verify with a thermometer rather than relying on time.

Marinade option: Marinate in olive oil, lemon juice, garlic, and rosemary for 2–4 hours before cooking. Pat dry before applying the mustard and breadcrumb coating.

Two racks: Cook sequentially unless your air fryer oven has multiple rack positions — overcrowding restricts airflow and causes uneven cooking.
