Garlic Herb Mustard Air Fryer Chicken Legs

Tangy lemon and Dijon mustard marinade infuses tender chicken legs with fresh garlic and herbs before quick air frying to crispy, golden skin. This keto-friendly, low-carb dish takes just over 30 minutes hands-on cooking after a minimum 2-hour marinade. Perfect for weeknight dinners, meal prep, or casual entertaining. The bright acidity and herb flavors cut through rich chicken fat while maintaining juicy meat inside. Set apart by the reserved marinade drizzle and flexibility to use legs or thighs based on preference.

FAQ
Can I use boneless skinless chicken?
Yes, reduce weight to 600g and cooking time to 18-20 minutes total. You'll lose the crispy skin texture but retain tender, flavorful meat. Thinner pieces cook faster.
What if I don't have an air fryer?
Bake in a 200C oven on a lined sheet for 35-40 minutes skin-side up, rotating pan halfway. The skin won't crisp quite as much without circulating hot air.
How long can I keep leftover chicken?
Up to 3 days refrigerated in an airtight container. Reheat gently at 160C for 8-10 minutes to avoid drying out. Freezing not recommended due to skin texture degradation.
