Doneness
Leaves have shrunk to about a quarter of their fresh size and turned a deep matte forest green; a leaf picked up from the basket shatters between two fingers with a dry papery crackle. Any leaf that still feels limp or rubbery needs another 30–60 seconds, but pull the moment leaves start to look brown around the edges — spinach goes from perfect-crisp to scorched-bitter in 20 seconds at this temperature.
Oil & seasoning
Toss in a wide bowl with 2 teaspoons olive or avocado oil per 6 oz of spinach until every leaf has a glossy film — bare spinach leaves lift in the air fryer airstream and weld to the heating element. The thin oil coat also weighs the leaves down enough to stay in the basket and conducts the heat that turns the cell walls from limp to crisp.
Season with: fine sea salt (added BEFORE the cook so it sticks to the oiled leaf), garlic powder, smoked paprika, nutritional yeast for a cheesy-chip flavour, lemon zest after cooking, everything-bagel seasoning.
Watch out for
- Weigh the leaves down. Bare or under-oiled spinach is light enough to lift in the airstream and weld onto the heating element above the basket — that's a real fire risk, not theoretical. The 2 tsp of oil per 6 oz isn't optional; it's what keeps the leaves in the basket. Some cooks use a metal grate or perforated cover to physically pin the leaves down — that works too.
- Pull at exactly 5 minutes (or earlier if leaves are turning brown at the edges). Spinach goes from perfectly crisp green to scorched bitter black in under 20 seconds at 325 °F. Set a timer; don't trust the air fryer's auto-shutoff. Brown spinach chips taste like ash and ruin the batch.
- Strip thick stems before loading. The leaf crisps in 5 minutes but a thick stalk stays rubbery and chewy at the same time — pick the largest leaves, fold them and pinch out the stem, and discard. Baby spinach can usually go in whole; mature flat-leaf or savoy spinach needs the stem prep.
- Single layer non-negotiable. Stacked spinach leaves steam each other and the bottom layer ends up limp green soup while the top layer crisps. Cook in 2 batches if you have more than 6 oz — each batch is only 5 minutes so the total cook is still under 15.
