Hot Caramelized Onion Dip with Bacon and Gruyere
Sweet Onion, bacon, gooey cheese all mixed in with sour cream and mayo. An appetizer doesn't get more delicious than that!
SERVINGS: 6 servings
Ingredients
- 4 bacon strips
- 2 sweet onions halved and thinly sliced
- 1/4 teaspoon sugar
- 1/4 teaspoon sea salt
- 1 tablespoon dry sherry
- 1/4 teaspoon tabasco
- 1/2 teaspoon chopped fresh thyme
- 1 cup shredded Gruyere Cheese
- 1/2 cup sour cream
- 1/2 cup mayo
- 1/4 teaspoon freshly ground black pepper
Instructions
- Preheat oven to 400 degrees.
- Cook bacon in a large nonstick skillet. Remove to a paper towel lined plate to cool. Crumble.
- Add onions, sugar, and salt to bacon fat in the skillet and cook over medium-high heat for about 5 minutes. Reduce heat to medium and cook, stirring often, until onions turn a deep golden brown color. This can take as long as 20 minutes. If onions start to burn, turn heat down to medium-low.
- Add sherry and cook 1 minute. Stir in thyme and tabasco. Remove from heat.
- Mix together sour cream and mayo in a medium bowl. Add crumbled bacon, cheese, onion mixture, and black pepper. Mix together well and transfer to a 2-cup baking dish.
- Bake 20 minutes, or until bubbly and golden brown on top.

This is one of our favorites. Have made this twice, making again this weekend. Guests go crazy over this dip and will say “Who made this dip, amazing!” We have put this on barbecued burgers. Takes your burger to a whole new level. I have left out the sherry because I didn’t have any. Still turned out fabulous! Thanks for sharing this delicious dip!!!
Can I substitute sherry vinegar for sherry?
Sherry vinegar is very acidic whereas sherry has a somewhat sweet flavor. You can leave the sherry out and it will still be good. Or just a little splash of sherry vinegar might taste good, but I would go really easy with it.
can mayo be substituted with greek yogurt? Or cream cheese?
Yes, either substitution should be fine.
WOW! This looks fabulous! My mouth is drooling as a scroll though the pictures! Can’t wait to make it!
Thank you 🙂
And I hope you like it!
Wow, I am drooling over here – this looks so fantastic! What a combination too, I would just need the whole pan and a spoon!
I would love this as a soup. Please share how to convert it
The best way to do it would be to find a caramelized onion soup recipe and then melt gruyere cheese on top and sprinkle with crumbled bacon.
Ive made this many times!!!! Always a favorite.
Glad you like it 🙂
Would love to try this for Christmas evening. Have you ever made it (or any parts of it) in advace?
I’ve cooked the onions in advance, but it would be fine to get everything prepared and mixed together a day in advance and refrigerate it. Then bake it just before serving. You may need to add about 5 minutes to the bake time since it will be cold.
I made this as an appetizer for Thanksgiving. I didn’t remember to pick up sherry, so I used balsamic vinegar instead. It was absolutely delicious! I got many compliments on this dip, it is a keeper.
This dip is a blue ribbon winner. I made it for a dip contest at work today and took home the first place award out of 16 contestants! In order to have it hold up for the duration of the contest, I put it in a slow cooker, decreased the sour cream and mayo a tad and added cream cheese. I can’t wait to give it a try in the oven though. Thank you for sharing this recipe!
Congratulations on winning the contest! Cream cheese sounds like it would be wonderful. I must try it that way.
I see in the picture that the dip is presented in the skillet. I have to plead ignorance about now knowing what a 2 cup baking dish is. Can you just mix all the ingredients in the bowl and transfer back to skillet? Can’t wait to try. Perfect football snack food!
You can bake it in any kind of baking dish or skillet so long as it is oven proof. The exact size doesn’t matter so much, but if you use a bigger dish and the dip is spread out in a thin layer, you might want to leave it in the oven for less time because it will heat faster. Hope you enjoy it!
Would it matter if I omitted the sherry? Thank you
It’s fine to omit the sherry. Hope you enjoy it!
Going to make this dip soon, have to get some ingredients, my family will love this at Christmas!
I hope it turns out wonderfully for you Kathy and everyone loves it! 🙂
Your pictures are AMAZING! I just made this and it is SOOO good, I took the best pic I could but shouldn’t have compared it to yours after, nice work- thanks for the recipe!
Ah, thank you! You’re so sweet. My photography has been a work in progress for a long time. Glad you enjoyed the dip. It’s one of my favorite things to eat. 🙂
I literally saw this and got up and made it! Baking right now, smells SOOOO good:) I used some leftover turkey bacon and red onions and Italian cheese blend and fresh Parmesan and neufchatel cheese instead of sweet onions and mayo. And I added some green pepper chunks 🙂 delicious!
The smell is the best isn’t it? Hope you enjoyed it 🙂
sounds great, but oh those calories!!! Does anyone have the breakdown on claories, sodium, cholestral , sugar, on this recipe.
I think it’s best not to know Margie. LOL. This is definitely an appetizer that’s best eaten on only rare special occasions and shared with lots of friends!
Making this for the 3rd time today! It’s been requested yet again! Amazing recipe, thanks!!!
I’m so happy to hear you enjoyed it ! 🙂
I’m assuming the cheese gets mixed in at the last minute before baking, maybe with another sprinkle on top for a pretty surface?
Oops! Did I not mention that? Will fix it.
No problem at ALL! The recipe looks gorgeous and I will be bringing it to my friend’s 50th bday this coming weekend. Making some tweaks but I’ll let you know how it goes!!!
Yes, please let me know how it goes! And Happy 50th to your friend.
I cant wait to make this, its looks & sounds awesome! Thanks for sharing!
Thanks Angie!
Oh wow does that look good! Pinning it to my “dips & sauces” board right now for future gatherings. Thanks for sharing.
Thank you! I’ll have to check out your Pinterest Boards. I’m a total fanatic!
