This is Hot Onion Dip Recipe is CHEESY

When we were at my parents for Christmas, we made this delicious hot onion dip recipe. My mom originally got this recipe from my Dad’s cousin by marriage, Paula Wallace (one of the very best cooks ever). Of course, Mom put her own spin on it…because it’s Mom, (have you checked out her site yet? Simply Sated is the bomb) and it is SO good.

We didn’t tell Pat what was in it, because I knew he doesn’t ‘like’ anything containing onions.  But he LOVED this hot onion souffle dip. That’s because hot onion dip doesn’t really taste like onions, even though the name suggests otherwise. I mean there’s SO much cheese in it, the onion flavor barely exists. Even after I told him that the dip contains onions, he continued to eat it! If you knew him, you would know how shocking that really is. And THAT is how you know it’s good.

This cheesy hot onion dip recipe is a winner 100%.

We just put ours in the oven!!! I'm excited to try it...we used smokey gruyere, a house fav :)
    hope you liked it!! i tried to comment below for you but it actually went under michael's for some reason. thanks for coming back to the site! miss you guys

Alright Becky, when I saw that your directions said "pour," I started to get concerned because the mixture I had was way to thick to pour. Sure enough, when it was done baking, not at all liquid or runny like your pictures. What did I do wrong???
    I think it will be fine. We just heated up the cream cheese to make it easier to mix. It should be the same once you bake it. 99% sure. Although I'm still def no expert :)
      Awesome!! Let me know if you like it! I'm always honored when you try stuff because you're such a professional!!
        I would be flattered if you thought I was a professional, but I think this is a misplaced reply hahaha
          oh, yes that was actually supposed to go to angela. but of course i think you're a pro as well michael!
    Hey Michael, this is Susie (Becky's mom) and she asked me to clarify. The onion souffle should be firmer than our pictures. For some reason, this one time, it turned out a little less firm than usual. We didn't actually heat the cream cheese before mixing, but we did let it come to room temperature before mixing. I hope this helps and explains. If yours did came out firmer, it is probably perfect. We will be sharing Onion Souffle Version II very soon, so we will keep you posted. Thanks so much for checking out our recipes.
      Thanks for the help! Heather assures me it was tasty, so I am satisfied!
        :) glad it worked out! happy wife, happy life!
I never came back to say it was SO tasty!!! I'm making it again tonight with smoky gouda for my Downton Abbey Season finale shindig...I know, I know...not so much English....but it'll be delish so no one will care :)
    i'm so glad you liked it!! and last night sounds like a great reason to make it :). that sounds amazing with smokey gouda...i'll have to make it like that next time
