Smoked Asparagus

Learn everything you need to know about how to make smoked asparagus and take this typically mundane side dish to the next level!

Whether you are using a pellet grill like a Traeger, Camp Chef, or Pit Boss, an electric smoker like a Masterbuilt, or just a conventional propane grill like a Weber, we've got you covered. 

Let's Go!

 

Why Smoked Asparagus?

Smoked Asparagus vs. Grilled Asparagus

Let's face it, everybody and their brother has been served a side of "grilled asparagus" at a neighbor or friend's backyard BBQ.

And while grilled asparagus can be delicious, most often it is served under seasoned, overcooked, limp, and burnt tasting.

Usually because whoever made it probably kept most of their attention on the burgers and steaks while the poor asparagus wilted away in some 700°F back corner of the grill.

 

Versatility and Convenience

The great thing about smoking asparagus, besides the enhanced flavors that come from the woodsmoke, is you have a lot more leeway in cooking times before the asparagus gets overcooked because you are cooking it at a lower temperature.

So it tastes better AND you are less likely to screw it up.

And you can throw a batch of asparagus on the smoker, grill, or pellet grill right along with your other food, so it couldn't be more convenient.

The trick is putting it ON the smoker at the right time and temperature, and also taking it OFF at the right time BEFORE it is overcooked, which we will get into more detail below.

 

How to Choose the Asparagus

According to foodtown.com, you should look for asparagus stalks that are firm to the touch, stand up straight, and have a smooth texture.

Stay away from asparagus that already looks limp or wilted.

Finally, the tips of the asparagus stalks should be closed and firm, not spreading or soft.

Equipment

If you want to use a vegetable basket like the one he uses in the video to keep your asparagus from dive bombing between the grates, check out this one that we like from Amazon.

 

Best Wood for Smoking Asparagus

Most likely your main wood choice will be based on whatever protein you are smoking alongside for the asparagus to accompany that day.

However, smoked asparagus is great to make while your giant hunk of meat is resting, or even if you are making something entirely different for it to accompany on another grill or inside the house.

So don't limit yourself to just whatever wood you are using to smoke the main course.

Mesquite and Hickory are two great wood choices that pair wonderfully with asparagus you should consider.

While the strong flavors from these two woods, particularly mesquite, can overpower many proteins during a long smoke, they work great when doing shorter smokes on vegetables and seafood.

You can impart A LOT of distinctive smoke flavor in a relatively short period of time.

Plus the strong favor of asparagus holds up well to the smokiness of both types of woods.

 

Trimming the Ends

The woody, fibrous ends of the asparagus need to be snapped off before smoking them.

You can do this with a knife and cutting board, but there is a much easier and effective way.

Pro Tip: Hold the fatter end of the asparagus about ¼-1/3 away from the end with two hands and your thumbs pointed together, pressed against the stalk and pointing away from you.

Then push your thumbs away from you like you were breaking a small stick or twig.

The asparagus will snap in exactly the right place every time, leaving you free from having to guess where to trim the asparagus or leaving too much woody root attached to the end of the stalk for your guests to have to chew through.

Lastly, and this is optional but works well on very thick stalks, you can use a peeler to peel the exterior off the asparagus for a more refined presentation.

 

Seasoning the Asparagus

You would never serve a beautiful rack of lamb or a prime ribeye steak to a guest without any seasoning, so why do so many people neglect to season their veggies?!

Make sure to brush on some olive oil to help your seasonings adhere and keep the smoked asparagus moist while cooking.

Asparagus NEEDS salt and pepper, at a minimum, no matter how you prepare it.

The next most important is a squeeze of lemon juice, squeezed on after its cooked (a good rule of thumb is that citrus should usually be added to meats and veggies AFTER they cook)

Add some butter and garlic, or go all out with a Bearnaise or hollandaise sauce, and now you are truly in business.

 

Best Temperature and Time

What Temperature Should you Smoke Asparagus?

The great thing about smoking asparagus is you that can really do it at any reasonable cooking temperature between 225-400°F.

We smoked our asparagus at 275°F.

But no matter what the asparagus is accompanying on the smoker, whether it's a slow cooking pair of lamb shanks at 225°F, or a roasted chicken or turkey crisping up at 350°F, you can throw the asparagus right on there with it.

 

How Long Does it Take to Smoke Asparagus?

Now, obviously the cooking chamber temperature you set for your protein is going to affect how long the asparagus takes to cook.

On the low end at 225°F, the asparagus will take about a full hour to cook,

On the high end if smoking at 350°F, the asparagus should be done cooking after only 10-15 minutes.

 

Your asparagus will eventually fully cook no matter which option you choose. So that leads us to the obvious question of: Which temperature is better?

All else being equal, the lower temperature will give your asparagus more time to absorb smokey flavor, and you will have a much lower risk of over cooking it due to the time it will take to cook.

At the higher temperature though, you may get a better crispy exterior on the outside of the asparagus, the asparagus will obviously be done sooner, but you do have the risk if overcooking it if you take your eye off of it for too long.

In our recipe below, we split the difference and smoked our asparagus right at 275°F for 35-45 minutes.

 

Option: Smoke the Asparagus While the Meat is Resting

One clever option, if you are smoking a larger roast like a lamb shoulder or a fresh ham at a low and slow temperature like 225°F, is to put the asparagus on AFTER you remove the meat from the smoker.

Large cuts of meat like this generally need about 20 minutes or longer to rest before serving.

This leaves you with the perfect time to crank the heat up on the smoker above 300° F, add some new wood like mesquite that you may not want to use on your meat, and then throw on the smoked asparagus.

You can now give the asparagus your full attention while the meat does its thing resting on the counter inside.

 

How Can You Tell When Smoked Asparagus is Finished Cooking?

Perfectly cooked asparagus should be tender but still crisp and definitely not limp.

Some culinary websites say the asparagus should still be bright green once cooked, however, on a grill or smoker where the asparagus is exposed to woodsmoke and combustible gases like from charcoal, you are likely to lose that bright green color pretty quickly.

This is ok.

Honestly, the most accurate way to check your asparagus is to taste test it.  Keep one spear set aside as your tester.

When you think they are getting close to finishing, take a bite. If it's not done, throw it back on and continue to test this same piece until it tastes just right,

Quickly remove the asparagus from the cooking chamber when they are done.

Pro Tip: Keep them spread out on a pan or cutting board, not stacked on top of each other.

If you stack them on top of each other the ones on the bottom are likely to overcook and start to get limp and soggy.

 

Using a Vegetable Basket or Pan when Smoking Asparagus

 

Use a Grill Basket or Phat Mat

Depending how many heads of garlic you are smoking, or especially if you are smoking individual cloves, it may be easier to manage a lot of them on a grill or smoker by using a grill basket or grill mat.

We are particular fans of the ORDORA Portable Grill Basket because it comes with its own handle, making it much easier to manage and move lots of delicate food, even shrimp, scallops, and asparagus around with one quick motion.

Another option is to use a grill mat, which are becoming increasingly popular in many BBQ circles, especially for delicate veggies and small seafood like oysters.

Our personal favorite is the PhatMat Non Stick Grill Mat.

Just throw it down on your grill to keep your smoked garlic all in one place and you can slide it around as needed to make room for other food without having to move each individual piece of food.

It keeps your grates really clean, and when you are done, you just throw it right in the dishwasher!

 

Pans and Skillets

Check out this Cast Iron Skillet on Amazon

If you don't have a vegetable basket, or want to make a sauce while you are smoking your asparagus like a garlic and butter sauce, then a pan is the way to go.

You can use either a disposable aluminum foil pan, or an oven safe skillet, like this cast iron one from Lodge we love to use that is also rated #1 on Amazon (we think with good reason).

 

Setting up your Smoker for Asparagus

New to smoking?

Like we said, you are most likely setting up your smoker to cook  main dish for the asparagus to accompany, and if so, make sure to follow THOSE instructions for setting up your smoker.

If, however, you are just in the mood for smoking some asparagus by itself, here are the best instructions for setting up different types of grills and smokers to do just that.

 

Vertical or Offset Charcoal Smoker

Weber Smokey Mountain on Amazon

Fill your firebox or lower charcoal basin with about a half a chimney's worth of unlit charcoal and create a small hollowed out depression in the center where you can add your lit briquets.

If your smoker comes with a water pan, like the Weber Smokey Mountain, don't bother with filling it just for some asparagus.

Light a charcoal chimney about ⅓ way with charcoal and wait about 20 minutes for it to fully ignite.

Once lit, add the briquets to the center depression you created.

Keep the dampers about ½ way to ¾ open until the temperature is to about 275-300 deg F.  Then slowly close them down until you are maintaining a temperature of 325-350 deg F.

Add 1 chunk of smoking wood once the smoker is up to temperature and put your asparagus on, preferably in a pan or vegetable grilling basket.

Electric Smoker

Masterbuilt Electric Smoker on Amazon

Plug your electric smoker in and turn the temperature to 325 deg F.

While it comes up to temperature, add smoking wood chips, not pellets, to the smoking wood tray.

Place your asparagus on the rack and close the door.

Pellet Grill

Fill the pellet hopper with your choice of smoking wood pellets, preferably mesquite or hickory if you are ONLY cooking asparagus and no other foods.

Plug in the pellet grill and turn the temperature to 325°F.

When the pellet grill has come up to temperature, place your asparagus on the grill, preferably in a vegetable grilling basket or pan.

Gas or Charcoal Grill

Check out this Weber Grill on Amazon

On a gas or charcoal grill you will likely need to use a smoker box filled with wood chips, or a pellet tube smoker filled with wood pellets.

Think you need a fancy smoker to smoke food at home? 

Think again.

Great smoked food can be made right on your current gas or charcoal grill.

Check out our Ultimate Guide to Smoking on a Gas Grill HERE.

If you are unfamiliar with these gas grill smoking devices mentioned above, no worries, we have you covered!

Read Everything You Need to Know about Smoker Boxes here, and see a selection of our Favorite Pellet Tube Smokers here.

In the case of asparagus, we would opt for the smoker box with wood chips since the asparagus will not take long to cook.  Save your pellets for longer smoking foods.

Set up your gas or charcoal grill for indirect cooking with the burners or a small amount of lit briquets on one side and plan for your asparagus to be on the other side.

Remember, we are cooking the asparagus INDIRECTLY, like an oven, not DIRECTLY over the burners or coals.

Once the temperature of your grill is around 300°F., place your smoker box or pellet tube smoker over the lit burners and once smoke begins coming out, place your meat on the opposite side.

Continue bringing the temperature up between 325-350°F.

Serving Suggestions

While asparagus usually plays a supporting role on the plate, there is no reason it can't shine as a co-star to whatever else you are serving alongside it.

 

Your smoked asparagus will undoubtedly stand out on its own even with just some salt, pepper, and  a squeeze of lemon to finish, however there are some additional options if you want to go a little bigger.

You can follow the recipe below to see how we smoked our asparagus in a pan with butter, garlic, and shallots, or try you own sauce recipe in the same fashion right on the smoker.

Alternatively, asparagus can be smoked and then drizzled with a balsamic reduction, and white wine cream sauce, or even a fancy Bearnaise or hollandaise.

Just try to make sure any sauce you add pairs well with whatever protein, starches, or other sauces you are serving as things will undoubtedly mix on the plate.
