French Onion Cheese Fondue

This French onion cheese fondue is my favorite cheese appetizer of all time. Put this out with a tray of dippers for a fun and delicious party food!

French onion cheese fondue

This French onion cheese fondue is on the short list of my all time favorite recipes. It is a winner on all fronts. It is 3-ingredient easy (plus a few seasonings), CRAZY delicious, and a hit at any party. I keep the ingredients on hand at all times so that I can make this when the craving strikes (or when unexpected guests show up).

This recipe was given to me by Reba Glasgow more than 30 years ago. She would always serve this at Auburn pre-game meals that we enjoyed in her Birmingham home.  I always looked forward to Reba’s fondue and am SO thankful that she shared the recipe!

When buying the condensed Campbell’s soup, make sure to buy Cheddar Cheese (not Nacho Cheese). Also, use prepared onion dip from the dairy case (not dry onion dip mix).

Note: This fondue must be kept over consistent heat to stay smooth and melted. There are a few options. If you love to cook and entertain, this Cuisinart electric fondue pot might be your best bet. It keeps fondue at the perfect temp and can be used for chocolate fondue or hot oil fondue (in which you cook pieces of meat or fish). If you prefer a slow cooker option, a smaller version such as the MaxiMatic 1-1/2-Quart Slow Cooker is preferable to a large crock pot. If you are just making this for your own family, just throw it on the stove and keep it on medium heat, stirring often.

Dippers: French bread cubes are an absolute must for this fondue. Pepperidge Farms French bread comes two loaves to a package and is what I usually use. Tostitoes, cauliflower and broccoli florets are also great with this.

Please let me hear back if you try this; I know you will absolutely love it! With football season here, there are plenty of reasons to make this. As always, thanks so much for stopping by. Be blessed, and stay savvy!!!
