Preheat the air fryer: Set it to 390°F (200°C). Preheating helps everything crisp evenly.
Prep your base: Pat your chosen base dry. If using potatoes, soak the cut pieces in cold water for 10 minutes, then drain and pat dry for extra crispiness.
Season: In a bowl, toss your base with olive oil, smoked paprika, garlic powder, salt, and pepper.
Coat evenly but don’t drench.
Air fry in a single layer: Add to the basket without overcrowding. Cook 12–20 minutes, shaking halfway. Timing varies: Potatoes: 16–20 minutes
Cauliflower: 12–15 minutes
Chickpeas: 12–15 minutes
Shrimp: 8–10 minutes
Make the harissa mayo: In a small bowl, mix mayonnaise, harissa, lemon juice, garlic (if using), honey (if using), and a pinch of salt until smooth.
Taste and adjust heat or acidity.
Serve: Pile the crispy base onto a plate. Spoon or drizzle the harissa mayo over the top, or serve it on the side for dipping. Finish with a squeeze of lemon, herbs, and a pinch of flaky salt.
