How to Buy Asparagus
Asparagus wrinkle as they age so make sure you choose asparagus that have a smooth skin, a uniform colour and perky tips.
Contrary to popular belief, thicker asparagus are as good and tender than thinner ones. They just need to be cooked slightly longer. Asparagus grow from “crowns” planted in the ground that have a lifespan of 15 years. Young crowns will produce thinner spears than older ones resulting in asparagus being available in different sizes.
How to Store Asparagus
Asparagus are best kept in the fridge where they will last 3-4 days. They will keep fresh better if they are damp, so keep them upright in a container with the ends submerged in a bit of water. You can also wrap asparagus ends in a damp kitchen towel. Whichever method you choose, make sure you cover up the asparagus bunch in plastic.
Below you’ll find step-by-step instructions for boiling, steaming, roasting, grilling and pan-frying asparagus, plus cooking times, seasoning ideas and answers to common questions.
Quick Answer: How to Cook Asparagus
To cook asparagus:
- Snap or trim off the woody ends.
- Rinse and pat dry.
- Choose your cooking method (boil, steam, roast, grill or pan-fry).
- Cook for 3–12 minutes depending on thickness and method.
- Season and serve immediately while tender and bright green.
How to Prepare Asparagus
Before you start cooking, proper preparation makes all the difference.
How to Trim Asparagus
Asparagus spears have tough, woody ends that need removing.
The snap method (easiest):
- Hold the spear near the base.
- Bend gently until it snaps naturally.
- It will break exactly where the tender part begins.
The knife method (for neatness):
- Line up the spears.
- Slice off roughly 2–3cm from the bottom.
If the spears are particularly thick, you may need to trim slightly more.
Should You Peel Asparagus?
You only need to peel very thick spears. Use a vegetable peeler to remove the outer layer from the lower half of the stalk. Thin and medium spears don’t require peeling.
How to Cook Asparagus (5 Easy Methods)
Different methods give slightly different results. Choose based on your meal and how much flavour you want to develop.
How to Boil Asparagus
Boiling is quick and ideal for salads or serving with sauces. But make sure you do not overcook the asparagus, otherwise they will turn into purée.
Method:
- Bring a large pan of salted water to the boil.
- Add trimmed asparagus.
- Cook for 3–5 minutes (depending on thickness).
- Drain immediately.
For extra colour and bite, plunge into iced water after draining. This stops the cooking and keeps it bright green.
Best for: Cold dishes, asparagus with hollandaise, or simple sides.
How to Steam Asparagus
Steaming retains more nutrients, firmness and flavour than boiling.
Method:
- Place asparagus in a steamer basket over simmering water.
- Cover with a lid.
- Steam for 4–6 minutes.
The spears should be tender but still slightly firm in the centre.
Best for: Healthy side dishes and light meals.
How to Roast Asparagus (Oven Method)
Roasting brings out a deeper, slightly nutty flavour and caramelised edges.
Temperature:
200°C (180°C fan) / Gas mark 6
Method:
- Lay asparagus on a baking tray.
- Drizzle with olive oil.
- Season with sea salt and black pepper.
- Roast for 10–12 minutes.
Thicker spears may need up to 15 minutes.
Best for: Serving alongside roasted vegetables, proteins or grains.
How to Grill Asparagus
Grilling adds a smoky flavour and light char.
Method:
- Toss asparagus with olive oil.
- Place on a preheated grill pan or barbecue over medium-high heat.
- Grill for 6–8 minutes, turning occasionally.
Look for light charring on the outside while the inside remains tender.
Best for: Summer barbecues and Mediterranean dishes.
How to Pan-Fry Asparagus
Pan-frying is quick and adds flavour from butter or garlic.
Method:
- Heat olive oil or butter in a frying pan over medium heat.
- Add asparagus in a single layer.
- Cook for 5–7 minutes, turning occasionally.
- Add garlic or lemon juice in the final minute.
This method gives slight caramelisation without softening the spears too much.
Best for: Pasta dishes, risotto or brunch plates.
How Long to Cook Asparagus
Cooking time depends on thickness and method.
| Method | Thin Spears | Thick Spears |
|---|---|---|
| Boiling | 3 mins | 5 mins |
| Steaming | 4 mins | 6 mins |
| Roasting | 10 mins | 12–15 mins |
| Grilling | 6 mins | 8–10 mins |
| Pan-frying | 5 mins | 7–8 mins |
Asparagus cooks quickly, so keep an eye on it to prevent overcooking.
