Special thanks to Traeger Grills for providing Sip Bite Go with the Flatrock grill for review. All opinions are my own.
What’s the difference between smoked VS griddled onions?
Onions cook a lot faster on the griddle… They turn out more “fried” when griddled, vs. when they’re cooked to melt-in-your-mouth deliciousness in the smoker.
What type of onion can be grilled this way?
Walla Walla, yellow onions like the one in this recipe tutorial, or red onions are all great choices.

How to make griddled onions
Now I’ll walk you through it…
Detailed recipe steps
- Prep all ingredients before cooking on the griddle. You’ll want them ready to use. I like to use a tray.
- Preheat Traeger Flatrock, Blackstone Grill, or whatever indoor griddle or outdoor flattop you’re using to medium-high.
- Add cooking oil to coat the griddle.
- Once oil is hot and shiny, add sliced onions on top. At this point, for the first ~ 5 minutes or so, until the onions begin to brown, we leave the flattop griddle open and regularly flip the onions so they don’t burn in any particular spot. If desired, you can add some more oil.
- Once onions on the griddle begin to wilt and become translucent, add salt and pepper. Continue flipping onions to season all over.
- Continue cooking griddled onions a few minutes, or as long as you’d like, to caramelize them to your desired doneness. In the Sip Bite Go recipe demonstration, you’ll see we shut the griddle lid at this point and turned down the heat to medium to brown them a few more minutes.
