Best Hot Onion Dip

This BEST HOT ONION DIP has been a family favorite for years. It doesn’t get better than Hot Onion Souffle for the holidays or game day!

I love dips (there are 68 dips on The Cookie Rookie so far!) and this HOT ONION DIP might be one of the BEST.  There’s nothing better than a great appetizer dip. I could eat it for each and every meal and never be tired.  With football season coming to an end (hello SUPER BOWL), and New Years Eve upon us…good dips are a great thing to try. This Best Ever Hot Onion Souffle is a must!

When we were at my parents for Christmas, we made this delicious dip.  My mom originally got this recipe from my Dad’s cousin by marriage, Paula Wallace (one of the very best cooks ever).  Mom put her 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.  He LOVED this dip.  Even after i told him it had onions, he continued to eat it.  If you knew him, you would know how shocking that really is. This dip is a winner 100%.

I love dips like this that are so easy.  Mix the ingredients together, bake, and serve.  No wonder this was one of the first recipes I made in life! Yum!

We served it with crackers and sliced veggies, but it would also be great with pita chips or pieces of toasted bread.  Mom also recently made it as a topper for baked potatoes. That has me intrigued…doesn’t that sound so tasty?!

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 :)
