Here we go team. Meet your new favorite dip – Roasted Onion Dip and your new favorite chips – Cape Cod Waves™ Potato Chips. First let’s talk dip…loaded with caramelized onions and shallots and herbs, plus sour cream and Greek yogurt, fresh chives and some of my favorite seasoning on earth. In one word… it’s perfect. And quite easy to whip up. And the onion / shallot mixture that is the base of this recipe is beyond. So much so that it might be a good idea to make a double batch because I found myself eating it by the spoonful before I could even get the ingredients together to make the dip.

Now all that’s left to do is hop on an actual flight to Cape Cod and make this exact recipe in some epic beachfront kitchen, serve it with these chips, maybe throw a lobster roll on the side and kick back and get ready to welcome summer. Sounds good?? How do we make this a reality?

    This looks amazing! Can you make it a day ahead, or do you suggest serving day-of?

  2. Liz @ Floating Kitchen

    Oh this looks mega good! Cape cod chips are my forever favorite! And combined with this dip = match made in heaven. What time does the party start…I’ll be right over! 🙂

  3. Dave S.

    Looks awesome! Is that the Everything bagel seasoning from Trader Joe’s?

  4. Sharon

    Can you please tell me where I can find the Everything seasoning that you have in your yummy recipe?

  5. Janice – Salads for Lunch

    I think I would eat the entire bag of chips before the onions finished carmelizing, they look delicious!

  6. Jeannie Benton

    What is “everything seasoning”? Did I miss something?

  7. Emily

    I made this yesterday to watch some NCAA basketball games with family. This dip was a hit! I have a tried and true pan-fried onion dip and this was by far easier to roast the onions and someone said it was even better than my other recipe!

  8. Jackie

    Hi, this looks amazing! I live in Australia where Everything Seasoning isn’t a thing – can you suggest some substitutes?

    Would it be as good if I caramelized everything on the stove top over low heat w/occasional stirring?

  11. Karen

    Made this for the big game day. My tasting(s) give this dip a big thumbs up! Next time, I would lover the temperature for the onions by at least 25 degrees to prevent scorching. I left out the “everything” seasoning and kept it to just salt and pepper so the flavor of the onions really gets top billing. This is a keeper.

    I made this tonight with vegan sour cream and vegan yogurt – hubby said it’s the best vegan dip he’s tried. Thanks!

  13. Lindsey

    I can’t find champagne vinegar. Is it OK to use white wine vinegar? or should I use something else?

  14. Ilka Thomas

    Btw-delish, Just extra that I don’t want to go to waste!
