3. Step-by-Step Cooking Instructions & Crisping Secrets

If you’re using an air fryer, shake the basket halfway through to prevent hotspots.

Meal-Prep Storage & Crispy Air-Fryer Reheating Guide
• Cool Before Sealing: Let cooked portions cool for 10 minutes before sealing in glass containers so steam never softens the crust (keeps 4 days in the fridge).
• Sauce on the Side: Store dips, drizzles, and fresh herbs separately until right before serving.
• 3-Minute Crispy Reheat: Reheat in a 380°F (193°C) air fryer or dry cast-iron skillet for 3–4 minutes to restore shatteringly crisp edges.
