Rehydrated Onions, Mcdonald's Style

"I worked at McDonald's many years ago. This is the way that they made the onions for the burgers. I did this to go with Recipe #106882. I'm guessing at the yield but you can get enough for 4-5 burgers depending on how much you like funky onions."

Ready In:


  • 1 tablespoon dried onion flakes
  • 18 cup water


  • Put onion and water in a small microwave proof bowl. Heat for 30 seconds on medium. Let sit 15 minutes or until the water has been absorbed. If the onions still seem wet you can press out the extra water with the back of a spoon. Spread onion on top half of your hamburger bun.

  1. Can't wait to try.I live for onions live McDonald's kind always have..will let u know..had to quit regular onions cause of stomach issues but never have a problem with McDonald's....thanks for the tip will let u know..
  2. it does work!!! glad im not the only one who ran to try it lmao. Didn't even have anything to put it on, just wanted to see.
  3. Don't use water. Use "Better than Bouillon".
  4. Mom always had these growing up. I was/am a hamburger fanatic and regularly use these. We didn't have microwaves in the 60's/70's though but hot water works just fine. Mom showed me this process around 8 yrs old and have enjoyed them since. Fyi: 1/8th cup = 2 Tablespoons, hence the mixture could state: "1 part onion to 2 parts water". Just saying and trying to simplify.
  5. I realize I'm late to this discussion, but I just had to add my two cents! These are perfection! I don't eat meat, so I put them on veggie and/or bean burgers and soy hotdogs. Absolutely heavenly! And so affordable to dress up a meal!


I'm a stay at home mom. I love to read and sleep, neither of which I get to do as much as I want. One day ;) My DH thinks cheese, bbq sauce and ranch dressing goes on or with almost everything. I lurked here a long time before I joined. Some of the recipes I've printed out are dated 1999. So as I make these recipes (some favorites, some untried) I will review them. <img src="" border="0" alt="Photobucket">, <img src="" border="0" alt="Photobucket"> <img src="">, <img src=""> <img src="">, <img src="">
