    How to make griddled onions

    Now I’ll walk you through it…

    Quick look at griddling onions on the flattop

    1. Preheat flattop griddle and prep onions. 
    2. Griddle onions with salt and pepper.
    3. Finish griddling until onions are caramelized to your liking.
    4. Enjoy.
    Cooking Griddle Onions with Traeger Grills Flatrock Griddle

    Detailed recipe steps

    1. Prep all ingredients before cooking on the griddle. You’ll want them ready to use. I like to use a tray. 
    2. Preheat Traeger Flatrock, Blackstone Grill, or whatever indoor griddle or outdoor flattop you’re using to medium-high.  
    3. Add cooking oil to coat the griddle.  
    4. 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. 
    5. Once onions on the griddle begin to wilt and become translucent, add salt and pepper. Continue flipping onions to season all over.
    6. 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. 
    7. Enjoy on your favorite foods like burgers, quesadillas, eggs and more…

    FAQs 

    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.

    Meat thermometer recommendations

    Every home chef needs a reliable meat thermometer to cook food perfectly. 

    On Sip Bite Go, you’ll often see me using:

    1. Meater thermometer – a fancy wireless thermometer that connects to a phone app – gifted to me from a Traeger partnership.
    2. ThermoPro digital thermometer – which has a wire that connects the thermometer to a display box outside the oven/grill. 

    It’s like being psychic! The great thing about either of the thermometers above is that I don’t have to take the food out of the oven to know the temperature. 

    How to use ‘em… What I do is stick the digital thermometer in steak, pork, chicken, whatever… Then put the food in the oven, on the smoker, or grill.

    While the meat cooks, it reads the temperature so I know exactly what temp meat is as it’s cooking. Without having to take it out and check. It’s really difficult to overcook food when you know exactly what temp it is inside!

    Are you a foodie, too?

    Hey home chef, hope that answers all your questions about making fried onions on the griddle. 

    Enjoy cooking and chat soon on Instagram / TikTok / YouTube.

    Hey, I’m Jenna Passaro.

    I develop easy recipes that can transform your kitchen into a restaurant – and you into a true home chef.

      

    Where to start?

    Learn the secrets to smoking tasty Traeger recipes and making pizza at home. And cook amazing tri tip steak dinners.

    Or, fall in love with something new to cook with your air fryer, pellet smoker, BBQ grill, sous vide cooker, and more…

    You’ll notice, I kind of geek out over new cooking trends and tools!

    My story. Growing up, I didn’t learn to cook.

    (I was actually banned from cooking for years)

    And then in my 20’s I didn’t have to cook because my job as an event planner involved a lot of travel and it was easier to eat out. At the time, I was 100% positive that restaurant food would always taste better than cooking at home, and there was nothing I could do about it.

    Until I fell in love with a chef. He would come over and cook me delicious meals right in my own kitchen. My mind was blown.

    Since then, I’ve been on a mission to figure out easy ways to make restaurant style food at home and share it here on Sip Bite Go.

    Love to eat out and travel? I can totally relate. See my guide on where to eat in Portland, OR.

    Never in a million years did I imagine I’d ditch the 9-5 lifestyle in my late 20’s, move across the country on a whim, start a new life, start a food blog, and write a book.

    But here I am!

    See my book on Amazon: The Home Chef’s Sous Vide Cookbook.
