Tips + Tricks

No. 1 --> To quickly and easily peel and onion, slice off both the root and stem ends, then, carefully (!) slit the outer most layer of the onion. Grab one side of the sliced layer, and simply peel it off.

No. 2 --> This smoked onion recipe relies on a longer smoke for a sweeter, more mellow smoker infusion, just like my smoked garlic. If you're looking for a stronger smoke flavour, slice the onions in half root to stem, leaving the ends intact - this will keep the onions from falling apart.

Key Ingredients

  • Onions: Choose firm, unbruised onions with a clean papery peel. While you can smoke any variety of onion, I think the best onions for smoking are yellow or sweet onions. Both yellow and sweet onions lack the bitterness of red onions, and tend to be more versatile and adaptable in more dishes.

How To Smoke Onions

  1. Preheat your smoker to 180f, according to the manufacturer's directions.
  2. Slice both stem and root ends off the onions and remove peels.
  3. Place the onions directly on the grill grates and smoke at 180f for 60 minutes or until the onions start to soften and have a smoky aroma.
  4. Remove onions from smoker and prepare as desired. See below for ideas!

How To Use Smoked Onions

These onions aren't a one-trick pony! Due to the low temperature and relatively short smoking time, the onions soften slightly but still retain a lot of bite. They can be used in any recipe that calls for onions! Here are a couple of great ways to use your smoked onions:

Caramelized Smoked Onions

  1. Once onions have been smoked and slightly softened, slice them and add to a skillet with butter, lard or bacon grease, using 4 onions: 1/4 cup fat ratio.
  2. Heat the onions over medium-low heat, stirring often until the onions are browned, sugars have caramelized and they are fragrant.
  3. Use the smoked caramelized onions anywhere you'd regularly use onions.

Add Them To Other Recipes

Traeger smoked onions are perfect for adding to any recipe calling for onions. Simply prepare them according to recipe requirements. Use them in your smoked brisket chili or meatballs, to top your baked potatoes, or even in your chicken noodle soup for an extra savory spin.

Dress Up Classic Dishes

Add smoked sliced onions to tacos, nachos, wraps, burgers, or sandwiches to give a little extra pizazz! Heck, use them in dips and even jams!

Use them as a topping for your smoked pizza, especially if you've done the Traeger Pizza Oven Hack!

Smoked French Onion Soup

Umm hello!

Use your smoked onions to make smoked french onion soup, it's to die for!

Preserve Them!

Because this recipe is so quick and easy, and isn't hard to multiply, make a double batch to dice and dehydrate for later use.

Dehydrated onions can be used in diced form or blended up to make a smoked onion powder that would be a kick-ass ingredient in your brisket, ribs, or even chicken rubs!
