Prep: Set smoker temperature to 225℉. Trim 1 pound fresh green beans, as necessary, and set aside.
Blanch Beans: Bring a large pot of water to a boil and have an ice bath ready. When water is boiling, add green beans and set timer for 2-3 minutes (the longer you blanch, the softer your green beans will be). Remove and immediately transfer to an ice bath. Let soak in the ice bath until cooled through.
Season Beans: Prepare a grill basket or use a piece of heavy duty aluminum foil to create a tray; if using foil I recommend spraying with a non-stick cooking spray to prevent sticking. Pat green beans dry with a paper towel and then place in the basket in an even layer. Drizzle green beans with 1-2 tablespoons extra virgin olive oil and sprinkle generously with 1-2 teaspoons kosher salt. Toss to coat. (optional: add some ground black pepper, garlic, lemon zest and/or 1-2 tabs of butter or ghee).
Smoke: Place basket of prepared green beans on the smoker and close the lid. Let smoke for 30-60 minutes or until they have reached your desired doneness.*
Serve: Remove and toss the green bean mixture in the melted butter with a pair of tongs. Enjoy!
Notes
Blanching Green Beans: yes, this is necessary! We tested without blanching and found that by the time the green beans were done, they were so shriveled they were almost inedible. Blanching first works helps to maintain the perfect crisp texture!
Smoke Time: the ultimate smoke time will depend upon a variety of factors including humidity, outdoor temp, hot spots on your smoker, etc. It will also depend upon how soft you like your beans.
Cooked but a little crisp: blanch for 2 minutes and smoke for 30 minutes or so.
In the middle: Blanch for 2 1/2 minutes and smoke for about 45 minutes.
Softer: I would recommend blanching for 3 minutes and smoking for 45-60 minutes. The green beans may start to get a bit wrinkly with this method.
Check along they way: given the nature of smoking, I would check their crispness along the way using these timelines as your guideline!
Variations: feel free to add in some sliced onions, bacon or even some shredded parmesan cheese! So many different ways you can go with this base recipe.
Pellet + Wood Chips: I would recommend hickory or pecan for this recipe, but you really can't go wrong!
