Air Fryer Roasted Garlic
Roasting garlic is a steam-then-brown problem, and the air fryer solves it in two stages: the head cooks wrapped in foil, where its own moisture softens the cloves to a spreadable paste, then the foil opens for the final minutes so the exposed tops caramelise. Raw garlic’s bite disappears entirely — what squeezes out is sweet, mellow and ready to spread on toast as it is.

Ingredients
- 4 whole heads of garlic
- 4 tsp olive oil
- ½ tsp fine salt
- Fresh thyme sprigs (optional)
Method
- Slice the top quarter off each head to expose the cloves. Peel away loose outer papery skin, keeping the head intact.
- Set each head cut-side up on a square of foil. Drizzle a teaspoon of oil over the exposed cloves, letting it seep between them, and sprinkle with salt. Wrap snugly into a sealed pouch, leaving a small dome above the cut top for steam.
- Air fry at 380°F (190°C) for 20 minutes, pouches seam-side up so the oil stays around the garlic. The foil is not optional here — unwrapped garlic dries and scorches before it softens.
- THE OPEN FINISH: unwrap the tops for the final 5 minutes so the exposed cloves caramelise to a deep gold. Small heads may be done at 20 minutes total; large heads take up to 28. A clove should yield completely to a knife tip.
- Rest the heads wrapped for 5 minutes — the steam finishes the softening — then squeeze from the base and the cloves slide out as a golden paste.
Tips that actually matter
- The squeeze test through the foil tells you everything: the head should feel like a stress ball, not a stone.
- Tops dark but centres firm? Re-cover with an extra layer of foil, drop 10–20°F, and continue in short bursts.
- Make a batch: roasted garlic freezes in ice-cube trays for a month — one cube is a head’s worth of instant flavour.
- Stir a whole head’s paste into softened butter for roasted-garlic butter; keep a week in the fridge.
- Never let the foil pouch touch the heating element — keep pouches low and centred in the basket.
Why this recipe works
Roasting garlic is really two processes sharing one ingredient: steam to soften, dry heat to sweeten. The foil stage and the open stage are those processes given separate minutes instead of being left to fight it out, which is why the wrapped-then-opened method beats both the always-wrapped and never-wrapped versions.
Variations to try
The same vegetables, new accents: smoked paprika and cumin for a Spanish lean; curry powder and a squeeze of lime; everything-bagel seasoning after cooking; Parmesan and lemon; or chilli crisp spooned over at the table.
What to serve with it
Spread on toast as it is, mashed into butter, or stirred through the roasted potatoes on this site.
Storage & reheating
Fridge 4 days in oil; freeze as paste in ice-cube trays up to 1 month. Never store homemade garlic-in-oil at room temperature.
Frequently asked questions
- Do I really need the foil?
- Yes. Foil traps the garlic’s own steam so the cloves soften before they brown. Unwrapped, the exposed tops dry and scorch while the centres stay raw.
- Why is my garlic still firm?
- The head was large or the pouch leaked its steam. Re-wrap tightly and give it 3–5 more minutes; judge by the squeeze, not the clock.
- What do I do with roasted garlic?
- Spread on toast, mash into butter, potatoes or dressings, stir through pasta — it is sweet and mild, nothing like raw garlic’s bite.
