What goes into this recipe

- Asparagus: Use fresh, firm stalks with bright green colour and no brown spots. Both standard and thin varieties work — thinner spears cook faster and are more tender.
- Olive oil: Extra virgin olive oil adds flavour and helps seasonings adhere.
- Seasoning: Sea salt and freshly ground black pepper are all you need, but feel free to add herbs, lemon or cheese at the end.
How to grill asparagus
This foil technique keeps asparagus tender and flavourful while protecting it from direct flames.
- Preheat your grill to around 200°C / 400°F.

Step 1: Rinse the asparagus and pat dry. Snap off the woody ends by bending each spear until it naturally breaks where the tender part begins.

Step 2: Alternatively, trim the ends with a sharp knife if you prefer a neater finish.

Step 3: Lay a sheet of aluminium foil and arrange asparagus in a single layer so they cook evenly.

Step 4: Drizzle with olive oil and season with sea salt and freshly ground black pepper.

Step 5: Cover with a second sheet of foil and seal into a tight parcel so steam builds inside while grilling.

Step 6: Place the foil packet on the hot grill. Cook about 5–7 minutes per side, depending on spear thickness, until the asparagus has softened but still has a slight bite.

Step 7: Remove from the heat and let the packet rest for 3–5 minutes to allow the juices to settle.

Step 8: Open the foil carefully and serve with your favourite toppings.

Expert tips
- Thoroughly clean the spears and remove any tough fibres near the base.
- Grilling in foil prevents spears from falling through the grates and keeps them moist.
- Use a grill pan or the oven if you don’t have a barbecue; the method translates well.
- For large groups, make multiple smaller foil packets rather than overcrowding one — up to about 10 spears per packet.
- Avoid overcooking: asparagus should be slightly tender and still have a little bite.
- Use caution when opening hot foil packets to avoid steam burns.
FAQ’s
Soaking is not necessary. If spears are very thick, you can blanch them briefly in salted boiling water, shock in ice water, pat dry and then grill in foil to reduce grilling time and ensure even cooking.
Sogginess usually comes from overcooking or overcrowding the packet. Keep portions moderate and grill only until the spears soften slightly.
Cook the sealed foil packet on a hot grill about 5–7 minutes per side, depending on thickness, until tender but not mushy.
