The BEST baked dip EVER: Onion Soufflé

The BEST baked dip EVER: Onion Soufflé

How is it possible for 4 common ingredients to taste so wonderful – just because they are mixed together and baked into a hot, bubbly perfection?? I really don’t know, but every time I make this, I always find myself amazed. Well, amazed and full. This is one of those treats I.CAN’T.STOP.EATING.!!!

I got this recipe from my MIL – who has been making it for many years. It immediately became a family favorite. I have seen similar recipes on the web, which just goes to show how very tasty and perfect this dip truly is!


I love sweets – but I LOVE dips, especially hot, baked, melty, oozy, salty, creamy dips. And this one is the Queen of all hot dips. I mean – with a name like SOUFFLÉ, it should be Queen of Dips ((haha)).


I seem to always have several random chunks of cheese stored in the drawer of my fridge ((is that just me??)). This recipe is a perfect way to use up those leftover cheese bits because this recipe turns out deliciously regardless of the variety on hand. Well, probably a processed block of American cheese may not be the greatest.

Save a few tablespoons of each type of cheese you use to sprinkle on top – for extra melty yumminess!

This recipe easily doubles or even triples depending on how many will be joining you to partake of this warm, cheesy perfection on a cracker.IMG_6797

One more handy tip: this dip ((before baked)) freezes perfectly. If you have double ingredients on hand, why not prepare a double batch and freeze half?? I just freeze it in a freezer baggie and then dump it into my baking dish, thaw and bake. Perfect for those times when I want to serve something special to company but am running low on time or ingredients! Just be sure to keep a bag of sea salt pita chips or bagel chips on hand – those are my two favorites to serve with this dip. ((David loves Wheat Thins with this — so I thought I would share his fave too))


Now for the ingredient specifics:


  • Onions – need to be yellow & sweet and NOT old.
  • Mayo – needs to be Hellmann’s light ((because)).
  • Cheese – cannot be pre-shredded ((this recipe is not meant to include wood pulp – don’t know what I am talking about??? Google it, please. Your intestines will thank you.)) I always include freshly grated Parmesano Reggiano and some other white cheese, like an aged cheddar or a sweet Irish cheddar.
  • Cream cheese – the light off brand works great, save the extra 90¢ and get yourself a Sonic Happy Hour.
  • A dash of pepper in and on. I LOVE McCormick’s Montreal Steak seasoning. Just a few shakes while mixing and a dash on top adds just the prefect last touch.


Would you like to spice it up??  Trying adding several dashes of your favorite hot sauce or pepper jack cheese. 


I call this dip, the diet buster. I just cannot seem to rest until every last bit is gone. It’s a problem. But the good kind of problem to have, ha!
