Ingredients

  • Oil - A little bit of oil to cook the onions. Use your choice of a high smoke point oil
  • Frozen Onions - frozen onions are pre-chopped meaning you save on prep time and honestly cutting onions always makes my eyes tear up.
  • Cream Cheese - For best results, use full-fat block cream cheese. Low-fat cream cheese may separate when baked. You want it softened to easily mix into the dip. Set the cream cheese out at least 30 minutes before using.
  • Mayo - adds to the creaminess of the dip!
  • Pepper - Just a little bit of seasoning!
  • Parmesan Cheese - I use the pre-grated cheese for ease but freshly grated parmesan will give the best flavor.
  • Buffalo Sauce - I use Frank's Buffalo Sauce. This can be substituted with your favorite hot sauce for a spicer dip.
  • Green Onion - Break the green onion into whites and green parts. The whites are cooked with the frozen onions and the greens are added on top for a bit of color.

Expert Tips

  • Make it Spicy - if you are looking to make your dip spicy you can cook the onions with jalapeño or replace some of the buffalo sauce with a spicer hot sauce. Buffalo sauce usually contains hot sauce and butter making it a delicious mild rather than spicy.
  • Re-heat & Eat - If it's still in it's 9x9 pan, you can heat it in the oven until hot. For quick convenience though, place a large spoonful into a microwavable safe bowl and heat for 30 second intervals until hot.

Recipe FAQ

Can this dip be made ahead?

Yes! If you’re planning to make this buffalo chicken dip for an upcoming party and want to do it ahead of time, simply make the dip 1-3 days ahead and don’t bake yet. Keep in the refrigerator, wrapped in plastic wrap until you’re ready to bake then bake right before you’re planning to serve.

What can I serve with buffalo onion dip?

Here's a list of dipper ideas:
- carbs: tortilla chips, crackers, crostini, pretzel chips, potato chips
- vegetables: sliced peppers, carrots, celery

Can I use fresh onions for this recipe?

While I like using frozen onions because they are pre-diced. It saves on prep time and no tearing up from chopping to many onions.

However, you can definitely use fresh onions for this recipe. Just get ready to chop and dice a lot.
