Ingredients
The ingredient list is short and sweet for this cheesy onion dip.

Ingredient Notes:
Caramelized Onions: Yellow, Vidalia or Walla Walla onions are the best choice for this dip.
Cheese: Gruyere is a smooth melting type of Swiss cheese that's made from whole cow's milk. It's often described as both sweet and slightly salty. It's a perfect cheese for warm dips because it melts so smoothly.
Cream Cheese: Full fat or reduced fat cream cheese will both work in this recipe.
Sour cream: Full fat sour cream will give you the best flavor but light will work in a pinch.
Worcestershire Sauce: There isn't a lot but it helps balance the flavors of the dip.
Chives: Fresh chopped chives add a pop of color and a hint of garlicky flavor.
Bacon: Use your favorite bacon, just cook and crumble ahead of time.
Instructions
This easy dip comes together really quickly, especially if you caramelize the onions ahead of time.

Cream together the cream cheese and sour cream until smooth. Add the chives, bacon, caramelized onions, shredded cheese and Worcestershire sauce and stir until combined.

Preheat the oven to 425°F. Place the dip in a cast iron pan and sprinkle with 2 tablespoons of shredded Gruyere cheese. Bake until bubbly and serve immediately with crackers or bread.

Expert Tips for the Best Onion Dip
✘ Make the caramelized onions ahead of time. The hardest thing about caramelizing onions in the time it takes. The onions will keep in the fridge for 2 weeks so its easy to plan ahead and have them on hand.
✘ Shred the cheese at home. Freshly shredded cheese melts better because it doesn't contain the anti caking coating that bagged cheese has.
✘ Use room temperature cream cheese and sour cream. Room temp ingredients are easier to mix together.

Lynn says
15 cups of onions ...??is that right?? Looks delicious though but seems like a lot if onion????
Lisa says
Hi Lynn, it's 3 1/2 cups onions! Enjoy the dip!
Ruba says
If I don't eat bacon, can I sub mushrooms for that?
Lisa says
That sounds delicious! I have not tried making it with mushrooms, but the flavors should work. Just make sure you drain the extra liquid off the mushrooms after you cook them so you don't have a runny dip. Let me know how it turns out if you try it!
Rachel Pikutis says
Mushrooms absolutely work, and with the bacon too. I take frozen mushrooms (the frozen part is important), and I mince them up and throw them in with the onions in the last few minutes of caramelization. You can’t really taste them in the final product except that it adds yumminess. I also add in fresh thyme leaves at this point, and fresh thyme on top with the chives before baking.
Beth G says
Can olive oil mayo be used instead of canola?
Lisa says
Yes! I use it all of the time! Enjoy the dip, it's one of my favorites!
Stephanie Long says
Amounts for mayo and sour cream are "?" ...how many cups of each?
Lisa says
They are both 1/3 cup. The recipe has been updated, thank for catching that!
Rachel says
Any suggestions for a substitute for the mayo?
Lisa says
You could try Greek yogurt. I haven't made it that way, but it should work. Let us know how it turns out!
