Sous vide cooking is a “low temperature, longer duration” cooking technique. It locks in flavor and cooks ingredients perfectly every time you cook. It’s a great way to cook asparagus (and other vegetables) because this method of cooking reduces the chance of under or over cooking your vegetables. This article covers all things sous vide asparagus – including the best sous vide temperature and time to use, tips on what to accompany it with and a guide to the best social channels to learn even more about creating the ultimate asparagus dish.

Can you sous vide asparagus?
You can and you should. Ever eaten wooden asparagus? What about super squishy asparagus? If you are after the perfect asparagus, then you need to take up sous vide cooking (3 gold stars for those of you who have already discovered the meal changing brilliance of sous vide cooking).
Sealing asparagus before cooking it in your sous vide water bath helps retain the natural plant sugars which would otherwise be diluted in a large pot of water. That means you can expect brighter colored asparagus and fuller flavor every time you cook it sous vide.
Here’s your ultimate sous vide asparagus cooking guide. Read on…
Preparing asparagus before your sous vide cook
Line the asparagus up on your cutting board, with the bottom of the ziploc or vacuum seal bag as your guide to how long your asparagus should be cut. Using a sharp knife, carefully cut the asparagus so that the lengths are about the same size as the bag to enable the asparagus to fit snuggly.
Season the asparagus lightly with oil, salt and pepper. Place the asparagus into your ziploc or vacuum seal bag, so that the bottom of the asparagus is flat within the bag.
How to sous vide asparagus
Here’s the secret to tender, crisp and flavorsome asparagus. Sous vide it and create the most scrumptious asparagus every single time.
Water immersion method
Place the asparagus into your ziploc bag, so that the bottom of the asparagus is flat within the bag. With the top of the ziploc bag open, carefully submerge the bag into the bottom of the water bath, without allowing any water into the bag itself.
The pressure of the water circulating around the outside of the bag should push any air out of your food pouch and form a seal around the asparagus. Using the side of the water container, carefully seal the bag and leave the asparagus to circulate in the water until the vegetables are tender, for about 40 minutes.
To serve: Using tongs, carefully remove the asparagus from your ziploc bag into a warmed platter and serve immediately.
Vacuum seal method
Prepare your asparagus as instructed above. Then place your asparagus in a vacuum sealer bag and seal it. Follow cooking instructions as above.
Recap of the basic steps you need to follow:
- Firstly trim off the dry ends of your asparagus spears. Some sous viders use a vegetable peeler to peel the asparagus from the tip towards the base as well
- Put your asparagus in your vacuum sealed bag or ziploc bag (both options work well. Check out our article about the difference between the two bagging methods to work out what method you prefer)
- Cook the asparagus in your water bath or sous vide water oven as per the instructions of the specific sous vide product you are using
- Remove the asparagus from the food pouch and serve
We’ve got a floater!
Asparagus spears are not very heavy. And vegetables containing more liquid and fibrous properties than proteins are prone to floating in your sous vide water bath.
This can cause a small problem when you are trying to keep your vac seal or ziploc bag under the surface of your water bath. Check out our hints and tips for keeping your food pouches under water for the duration of your sous vide cook. Floating food pouches equals uneven cooking.

White asparagus sous vide temperature
There is a difference in taste between white asparagus and green asparagus. Most people report that green asparagus has a “vegetable” or “grassy taste” which people don’t taste in white asparagus. White asparagus tends to have its own distinct taste, which is less pronounced than in green asparagus.
White asparagus is grown underground and is not exposed to chlorophyll from the sun. It’s more tender than green asparagus but is prone to becoming stringy if its a little old when you buy it. Some say that green asparagus contains more nutrients than white asparagus (due to being grown in the dark).
If you want to experiment with sous vide white asparagus, here’s a white sous vide asparagus on a St George’s mushroom mayonnaise foam recipe from FusionChef to inspire you.

Reddit has a very active sous vide cooking community who enjoy sharing their hints, tips, successes and the occasional sous vide cooking fails with other sous vide enthusiasts. Here are a couple of Reddit threads about sous vide aspsaragus you might find helpful:
Sous vide asparagus – Can I reheat it?
Most sous viders prefer to eat their sous vide asparagus straight from their sous vide water bath. Whilst technically you should be able to “rethermalise” (reheat) asparagus, many find that this can make your asparagus a little mushy and it can lose a lot of its beautiful green color.
Given asparagus takes between 10-15 minutes to prepare (depending on your sous vide machine of choice), it makes sense to eat it fresh each time if you can.
