READY IN: 5mins
Recipe by Wildflour

This recipe is from the 1968 McDonald's Manager's Handbook put out in 1969 (1968 year) They quickly removed the recipe after realizing they had a very appealing "secret sauce." It was included as an emergency recipe in the event a particular store ran out of the pre-made sauce. Enjoy!

Being a sauce lover, (especially burger sauces), I found this to be the best one yet! I've also posted a recipe for the Big Mac version, but this one is much better. After trying pricey store-bought ones and several different recipes that came up short, I'm so happy to have found this one! I doubled the ingredients and filled my burger sauce jar and still have some leftover. I used lowfat Hellman's and lowfat Miracle Whip and it turned out delicious. (A real plus, because now I can slather it on with less guilt.) I also used Marzetti's creamy Country French dressing. I think this tastes better than McDonald's! The key to it's yumminess could be the combination of mayo and Miracle Whip, along with the two relishes. Also, the dried onions seem to work better than the fresh used in some of the other recipes. Some people say a burger only needs sauce when it doesn't deliver on juiciness and flavor, but I don't agree. This recipe is so fabulous, it's worthy of sharing the spotlight with Burger Of The Gods. Thanks for posting!

  • 14 cup Miracle Whip
  • 14 cup mayonnaise

  • 1 teaspoon ketchup
  • 18 teaspoon salt


  1. Mix everything very well in a small container. (No streaks!)
