Baked Caramelized Onion Dip
You know how much I love a good dip recipe. I suspect that half of my recipe collection on Inspired by Charm is different dip recipes! (You can find a collection of my favorite dip recipes HERE.) So when my Tastes of the Seasons blogger friends and I decided to whip up some fall appetizer recipes, I knew immediately that I wanted to add my Baked Caramelized Onion Dip into the mix. (Before I forget, remember to check out all of the delicious fall appetizer recipes I’ve shared at the end of this post. They all look so tasty!)
I love this recipe for several reasons. First, it’s really easy to make. Yes, it does take some time to caramelize those onions, but it’s a very simple process. After that, it’s just mixing things up and tossing the mixture into the oven.
Second, the flavors are so rich and creamy without being too much. It’s one of those dips you just can’t stop eating.
Third, it’s perfect for any occasion. Whether you’re watching the big game, hosting Friendsgiving, having friends over to play cards, or watching your favorite weeknight TV show. This dip not only goes with everything, it’s a dish everyone will enjoy.
With all that being said, let me tell you how to make it.
How to Make Baked Caramelized Onion Dip:
In a large non-stick skillet (or cast iron pan) melt the butter and olive oil over medium heat. Add the sliced onions and cook for about five minutes stirring as necessary. Then add in the thyme, sugar, and half of the salt. (I’ve shared all the ingredient amounts and full instructions in the printable recipe card below.)
Stir to combine and cook until the onions are soft and golden brown. This will take about 20 minutes. Yes, it’s a long time, but it’s so worth it. Remove the onions from the heat; add in the balsamic vinegar. Stir to combine. Set aside to cool slightly.
We’re almost ready to bake, so now is the time to preheat your oven to 400 degrees F.
In a large bowl, stir together the cream cheese, parmesan cheese, gruyere cheese, sour cream, mayonnaise, half-and-half, garlic, black pepper, and remaining salt. After the onions have cooled slightly, stir them into the cheese mixture to combine.
Spray a medium cooking dish with cooking spray, then fill it with your cheese and onion mixture. I’ve used this round baking dish, but any medium sized oven-safe dish will be fine.
Bake for about 25-30 minutes or until golden and bubbly.
Once it comes out of the oven, serve it hot with sliced, toasted baguettes. They pair perfectly together!
And with that, your Baked Caramelized Onion Dip is complete and ready to be served.

Did anyone have grease pooling in the dip? The flavor is delicious.
I dislike mayo so wondering if I could increase the sour cream instead.
I’ve never made it that way so I’m not sure. You could … it just may affect the flavor.
Can you make this dish ahead of time?
This was DELICIOUS. Perfect for a cold winter’s night. Somehow, I can imagine a version of this that would have slightly more gruyere relative to the cream cheese/sour cream/mayo base, and I may tinker around with that ratio next time. But this is definitely a keeper.
What types of onions do you recommend? White? Vidalia?
Who doesn’t love caramelized onions…and then in a dip…with bread!? Yum!!! Thanks for the great recipe!
I’m wondering if this could be made in advance? Having a few friends over on Friday and don’t want to be futzing with this beforehand. Also how much does this recipe yield?
Yes. You can make everything advance and then bake before you’re ready to serve. It serves about 8-10 people.
All of these dip recipes look great. Because of social distancing, I wouldn’t prepare a large sized dish, but how about doing smaller individual sized oven safe dishes – add a big green salad and you have dinner. I would try to make a few more healthy eating changes to some of them. Add a glass of wine – fabulous.
Yep – single servings are a great idea!
This is to die for! Oh so good! I made it last night. Everyone loved it! Thank you! Thank you! for the recipe.
Aren’t the flavors sooooo good!? Glad you enjoyed it!
