Hot, bubbly, and delicious! This Baked Caramelized Onion Dip with Gruyere Cheese is absolutely insane! Well, not insane like Lizzie Borden, this is the type of insane your family will love!
I don’t believe there is a single ingredient that makes a more transcendent transformation than a simple onion when it is caramelized. There is something magical about the flavors that are gently coaxed out of the onion during its long vacation in the sauté pan. The final product forms the base of quite possibly the most luxurious dip to ever kiss your lips!

The final product will yield a cheesy Baked Caramelized Onion Dip with just the right amount of creaminess and more flavor than you would believe! This is a recipe you’ll want to keep in your back pocket for when you are looking for an appetizer that will impress!
I used an eight inch cast iron pan to bake this dip. However, any similar sized oven safe baking dish will suffice. Though, I find the smaller cast iron pan has a rustic look that perfectly matches the dip.

May 20, 2017 at 7:44 pmThe flavor is unbelievable . I used it as a filling for mini Caramelized Onion pies. Just use the premade frozen ones if you don’t have time to make them. Seriously delicious.
Fox Valley Foodie says
May 22, 2017 at 8:29 amThat sounds like a great filling idea!!!

August 2, 2017 at 4:47 pmThis sounds delicious. Is there any reason why I couldn’t make it as written and then reheat it in the microwave for a minute or so before serving. I’m thinking of taking it to an event some distance from home.

August 6, 2017 at 3:54 amMelted cheese typically does not reheat well. It will lose much of it’s creaminess and break into an oil slick. It would still taste good but not great.

November 24, 2017 at 3:36 pmOMG! Thank you for such a fabulous recipe. We were asked to bring a cheese appetizer for Thanksgiving with neighbors because another of their friends always brought wonderful crusty bread. Needless to say it was a great pairing. Also made the Reuben dip which was also a hit. Mixing up the triple chocolate snicker cookies now and can’t wait to try more of your recipes. You are a great Foodie!

December 11, 2018 at 12:55 pmI dont have a cast iron pan but what sizs pan woukd be good to use if i double the recipe? Also, do you think it would be safe to make the onions a day ahead? Cant wait to try thjs!
Fox Valley Foodie says
December 11, 2018 at 2:43 pmI haven’t measured it exactly, but a 9 x 13″ baking dish should work well, if you pour the mixture in it and find it is too big, just grab a smaller pan. Making the onions a day ahead isn’t a problem at all.
Christina B says
January 30, 2019 at 8:55 amThis recipe is being saved and made at every holiday! Such a hit! I made the onions the night before which was such a time saver. Just mixed and baked when I needed it.
I must have put too much cheese on the top or cooked a little too long though because my cheese split and got oily/clumpy on top.
So delicious! Making again and sending the recipe around!
