I’ll be honest—I never thought I’d be the person who brings a hot dip to every party, but here we are. This caramelized onion dip with crispy bacon and nutty Gruyère has become my secret weapon, and I’m pretty sure my friends only invite me over now because they know I’ll show up with this bubbling bowl of goodness. Trust me, once you taste how those sweet, jammy onions mingle with the smoky bacon and melted cheese, you’ll understand why I make it at least twice a month.

Ingredients
For the aromatic base:
- 4 slices thick-cut bacon
- 2 1/2 large onions (halved and thinly sliced)
- 1/4 tsp sugar
- 1/2 tsp salt
- 1 tbsp dry sherry
- 1/4 tsp hot sauce
- 1/2 tsp fresh thyme
- 1/2 tsp Worcestershire sauce
For the dip:
- 1 1/4 cups shredded Gruyère cheese
- 1/2 cup sour cream
- 1/2 cup mayonnaise
- 1/4 tsp black pepper
- 1/4 tsp garlic powder
Step 1: Render the Bacon and Start Caramelizing Onions
- 4 slices thick-cut bacon
- 2 1/2 large onions
- 1/4 tsp sugar
- 1/2 tsp salt
Cut the bacon into small pieces and cook in a large skillet over medium heat until crispy, about 8-10 minutes.
Transfer to a paper towel-lined plate to drain, then crumble into bite-sized pieces once cooled.
Leave about 2 tablespoons of bacon fat in the pan—this is liquid gold for flavor.
Add your sliced onions, sugar, and salt to the same skillet and cook over medium heat for 5 minutes, stirring occasionally, until the onions begin to soften and release their moisture.
Step 2: Build Deep Caramel Flavor in the Onions
- 1 tbsp dry sherry
- 1/4 tsp hot sauce
- 1/2 tsp fresh thyme
- 1/2 tsp Worcestershire sauce
Lower the heat to medium-low and continue cooking the onions for 20-25 minutes, stirring every 3-4 minutes to prevent sticking.
You're looking for them to turn a deep golden-brown color—this slow process develops the sweet, complex flavors that make caramelized onions special.
I find that a little patience here is worth it; don't rush this step or you'll lose that rich, sweet character.
Once deeply caramelized, add the sherry and cook for 1 minute to let the alcohol cook off, then stir in the thyme, hot sauce, and Worcestershire sauce.
Remove from heat and let cool slightly.
Step 3: Preheat Oven and Build the Dip Mixture
- 1/2 cup sour cream
- 1/2 cup mayonnaise
- 1/4 tsp black pepper
- 1/4 tsp garlic powder
While the onions finish cooking, preheat your oven to 400°F.
In a medium bowl, combine the sour cream, mayonnaise, and black pepper, stirring until smooth.
Add the garlic powder and mix well.
This creamy base will bind all your flavors together.
Step 4: Combine and Assemble the Dip
- caramelized onions from Step 2
- cream mixture from Step 3
- crumbled bacon from Step 1
- 1 1/4 cups shredded Gruyère cheese
Fold the caramelized onions from Step 2 into the cream mixture from Step 3, then gently fold in the crumbled bacon from Step 1 and the shredded Gruyère cheese.
I like to reserve a small handful of cheese to sprinkle on top before baking—it creates a wonderful golden crust.
Transfer the dip to a baking dish (about 8x8 inches or similar) and smooth the top, then sprinkle with the reserved cheese if desired.
Step 5: Bake and Serve
Bake the dip for 20 minutes until it's heated through and the top is bubbly and lightly golden.
The dip will come out piping hot and fragrant—let it cool for just 2-3 minutes before serving with your favorite crackers or bread.
This gives it time to set slightly so it holds together better when scooped.
