Print Recipe


  • 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


  • 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.

  1. Made this today, hanging around the house with family…….absolutely amazing!!!! Easy to make and the flavors combined make for a perfect grown up onion dip !!!!

  2. This was so good! Made it yesterday to take to a New Year’s party and it was a hit! Seriously devoured within minutes. I didn’t have bacon so I used pancetta instead and It was delicious. This is definitely a keeper! Thanks for a great app recipe:)

  3. I serve this as an appetizer and it was awesome! I served it in a pumpernickel bread bowl. Everyone loved it and wanted the recipe. I’ll be making it again and have while watching the football game.

  4. OMG… My daughter made this dip and it is the bomb!!! We all loved it! I am making it for New Years now. Thank you for sharing πŸ™‚

  5. Such a great recipe! I found this in Coastal Living magazine. So awesome that you added a bit of Tabasco so you could claim the recipe as your own and blog about it!

    1. Such a great comment! I found this needless and passive-aggressive. So awesome that you chose to be a sarcastic jackass so you could claim the moral high ground and bitch about it!

  6. Will this fill a cast iron skillet that is 10″ in diameter? Two cups doesn’t seem like much but the pictures show it it a skillet.

  7. 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!!!

    1. 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.

    1. 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.

  8. 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.

  9. 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!

  10. 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!

    1. 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!

  11. 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!

  12. 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 πŸ™‚ delicious!

  13. sounds great, but oh those calories!!! Does anyone have the breakdown on claories, sodium, cholestral , sugar, on this recipe.

  14. I’m assuming the cheese gets mixed in at the last minute before baking, maybe with another sprinkle on top for a pretty surface?

      1. 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!!!
