Slow Smoked Asparagus Bundles with Lemon and Garlic is a recipe made in heaven! Placing these on cedar planks to bring out that classic Pacific Northwest flavors and paired it with another PNW classic – grilled salmon.
Using a cedar plank on just about anything on your grill and smoker (even without any seasoning) just makes everything taste so deliciously earthy. Traditionally, we all reach for the plank for our favorite fish recipes as the Salmon and Halibut but it doesn’t need to stop there. Grilling or smoking your veggies on a plank infuses a very gentle cedar flavor yet doesn’t overtake the flavor of the food itself.
🍽️ Why This Works
Easy – The most time you’ll spend actively working on the recipe is with tying the bundles together. Rest of the recipe is virtually hands off.
Portion Controlled – We had several friends over and it was easy just to grab a bundle and give it out. That way we made sure we had enough for everyone.
Great for Cookouts – Make these smoked bundles for your next BBQ as you can make a little bundle of 3-4 stalks for each person and then everyone can just grab a set to place on their plate next to their Grilled Hamburgers, Hot Dogs or Chicken.
🧑🍳 Ingredients
📝 Ingredient Notes
Asparagus – Look for fresh stalks that are firm and crisp. If the ends have started to wilt or feel sloppy, go ahead and pass. They really won’t smoke well.
Lemon Juice – You can squeeze your own or buy the juice separately.
Garlic – It takes just a minute to chop this and really complements the flavor of the asparagus.
⏲️ Equipment and Tools
Cedar Planks – I used to buy the three packs found at the hardware store, but that got to be REALLY expensive! I since found that buying bulk online is a much more economical alternative. Save a few bucks as you’ll use these a lot in grilling!
Garlic Chopper – When you need to chop just a few cloves, I prefer the choppers with the wheels and the cutting blades. It makes life a lot easier.
Butcher’s Twine – You will find this at your local grocery store in the meat department, the little kitchen section and then just hanging on random hooks throughout the store. We buy ours from Amazon and Walmart and just keep 1-2 of them on hand as we use them more than we realize.
🔪How To Prepare Asparagus
Asparagus requires a good wash since it grows in sandy soil. I like to soak the asparagus spears in a large bowl filled with cold water for a few minutes which will soften the dirt. Then, I give them one final rinse under running water.
With all the dirt removed, pat dry the stalks.
Then, it’s time to trim the asparagus. Bend it near the fibrous extremity, and it will snap right where the woody part ends.
🔥Smoking Instructions
Step One: Set up the grill for indirect heat at about 250°. Start soaking your cedar planks. Even though we are cooking on indirect heat and the risk of it catching fire is small, it is a good habit to have.
Step Two: Grab three or four asparagus stalks to tie together for a single portion. If you have really thin stalks, you may want a few more for a single serving. Tie them tightly using butcher’s twine.
Step Three: In a small bowl, add the olive oil, lemon juice, garlic, salt and black pepper together. Mix well.
Step Four: Place the asparagus bundles in a large Ziploc bag and pour the olive oil mixture into the bag. Carefully work it around so all of the asparagus is evenly covered.
Step Five: Add the wood chips or pellets to the grill. I used pecan, but other strong-flavored wood such as hickory and mesquite would give asparagus a more intense smoky flavor. If you look at my free Wood Pairing Cheat Sheet you’ll find that veggies usually go well with milder wood but the harder varieties seem to work for smoked asparagus too.
Step Six: Remove the asparagus when they are fork tender and bright green. That should be about the 45-minute mark.
Note: Thinner asparagus shoots will smoke much faster, so check for tenderness early and don’t just rely on the time.
❗ Recipe Tips and Tricks
Use a Ziploc. This is one of my favorite tips. The large bags make marinating and coating foods so much easier than large bowls. Plus, it makes clean-up really easy.
Let the cedar planks soak for 30 – 60 minutes before using. It helps to minimize any burning.
For a fun twist, use cedar wraps as we did in the Copper River Salmon to hold the asparagus together instead of twine. You will need to cut these down a bit, as you don’t want to wrap the entire stalk. They cut easily with scissors and still give off that earthy, cedar aroma.
To achieve a stronger cedar plank flavor, don’t bundle the asparagus. This will take more planks and more space but you will have a stronger infusion of flavor.
We love the subtle flavor the cedar planks add to the asparagus bundles but they are optional! You can smoke asparagus directly on the grill grates or in a grilling basket if you’d like.
🧑🍳 Storage and Reheating
One of the funny things about smoking on the grill is that the smoke flavor will intensify the longer you let it rest, especially with vegetables. If you think you may have leftovers, use a bit less wood for smoking.
Seal leftover smoked asparagus in an airtight container and refrigerate for up to three days.
🍱Meal Prep
Make the marinade ahead of time. It takes just a few minutes to make but stores well in the refrigerator for a few days.
Wash, prep, and bundle up the asparagus bundles. Place in an airtight container up to 24 hours ahead.
Additions and Substitutions
If you like things with a bit of a kick, add some red pepper flakes to the olive oil mixture instead of lemon.
Grated parmesan at the end adds a phenomenal, slightly salty flavor that just works perfectly with smoked asparagus.
Make the asparagus plain and drizzle some fresh lemon juice at the end or serve with cut-up fresh cherry tomatoes for a fresh farmer’s market vibe.
Pull out your favorite seasoning mixes like the Spiceology blends Greek Freak or Garlic and Herb.
🍽️Serving Suggestions

❓ Recipe FAQ
Yes, you should or they may catch fire.
Smoke asparagus at 250 degrees F. for 45-50 minutes.
It is cooked when you can gently push a toothpick through it AND still get resistance. You don’t want mushy asparagus, so it’s best to not let it smoke too long. You want the little bit of al dente crunch. Our 45 minutes allowed a crisp, yet tender result.
Cut off the bottom parts where it tends to be white and woody. As the stalk gets greener, that is where you make the cut. Generally, I find that is about ¾-1 inch.
You can also bend the asparagus where the woody part meets the green and it will snap in the right place.
There are a few tips to looking fo the best asparagus.
1. Look for uniform size. When the bundle at the store has some thin and some thicker ones, it’s hard to cook the veggies evenly.
2. Look at the tips to make sure they look crisp and fresh. No wet ends, no soggy looking tips.
3. Look at the bottom and make sure that there isn’t too much of the stalk that you will be cutting off. As noted above, you will cut off the white section so if there is a lot of the white, you are going to be cutting that off and tossing it. Move to the next batch if that’s what yours looks like.
Simply use foil instead. Don’t roll it up but make a large piece that you can lay the asparagus on. Another option is to use a vegetable basket or place the asparagus directly on the grill grates.
Asparagus will be fork tender and bright green with the perfect al-dente finish after 45-50 minutes at 225 degrees f. There is no need to toss the asparagus halfway through.
Yes, but only for a few minutes. This quick soak is needed to loosen any stubborn grit that might be hiding in the tips of the spears. Follow with a quick rinse under running water to make sure all the dirt is removed.

Jason’s been firing up the grill for over 30 years after graduating from the US Coast Guard Academy. His love of finely-grilled steak and chicken led him to buy his first Weber grill to put on his apartment patio in 1992. Each military move led to a new grill (a mixture of gas and charcoal) until he fell in love with the Big Green Egg in 2008. Since then, he has added another 4 grills to the collection. Yes, he has a problem. Jason loves smoking in the ceramic BGE with exotic woods including olive wood from Egypt and hard to find varieties such as sassafras and orange wood. Jason takes the term “foodie” to a whole new level, jumping at the chance to take food tours and cooking classes during foreign travels. These have provided inspiration to incorporate new ideas into recipes when he gets back home. He has been featured in Fox News, Parade, Yahoo News, Kansas City Living and more. After retiring from the military and moving to southwest Florida, he has focused grilling and smoking locally sourced meats and fish (read: he likes to catch his own fish!)
