recipe tips
If you're hesitant about the raw onion flavor, caramelizing the onions lightly before adding them to the sandwich can introduce a sweetness that complements the peanut butter.
Applying peanut butter to both slices of bread before adding the onion can help create a barrier that prevents the bread from getting too moist from the onion.
Experiment with the thickness of the onion slices to adjust the intensity of the onion flavor in the sandwich.
Adding a light sprinkle of smoked paprika or cayenne pepper can introduce a subtle heat that works well with the peanut butter.
common recipe questions
Can I use any type of bread for this sandwich?
Yes, any type of bread can be used. Whole grain, white, or even rye could add different flavors to the sandwich.
Is there a specific type of onion that works best?
While yellow onions are commonly used for their balance of sweetness and astringency, red onions or sweet onions can also provide a milder, less pungent option.
Can I add other ingredients to this sandwich?
Some people add crispy bacon, sliced apples, or even lettuce for extra texture and flavor layers.
Is there a way to make the onion less overpowering?
Soaking the thinly sliced onion in ice water for about 10 minutes before draining and patting dry can reduce its sharpness.
Can I toast the bread?
Toasting the bread adds texture and a nutty flavor that can complement the creamy peanut butter and crisp onion.
How should I store this sandwich if I'm not eating it right away?
It's best enjoyed immediately, as the bread can become soggy from the peanut butter and mayonnaise. If you need to store it, wrap it tightly and keep it refrigerated for a few hours.
Can I use crunchy peanut butter?
Yes, crunchy peanut butter can add additional texture.
What can I serve with this sandwich?
Since the sandwich is quite unique in flavor, simple sides like potato chips, a plain salad, or fruit pair well with it.
Is this sandwich actually popular?
While not mainstream, this sandwich has its enthusiasts who appreciate its unconventional flavor combination.

July 27, 2021I tried this 40 yrs ago on a suggestion-loved it! I love raw onions with everything! Never had mayo on it though- Try this sandwich-surprisingly delicious!

I'll have to take everyone at their word, because I can hardly eat cooked onions, much less raw. I love peanut butter and bacon sandwiches though. My mom used to eat those. She would also have peanut butter sandwiches with dill pickles, or with banana and mayo, Ã la Elvis. I think they all sound better with bacon. That and chocolate fix everything.

My initial reaction was "GROSS!" However, with all the positive reviews, I think I will try it. What is there to loose except a few inexpensive ingredients I always have on hand?It takes me back to my youth when my sisters boyfriend loved peanut-butter, jelly and tuna sandwiches.

Dogowner REVIEW:
March 8, 2020My dad being a 1940s war time kid grew up on there but he eventually added egg and took off the mayo so that is what my family is used to. Both ways are good

The recipe and no one here has mentioned what TYPE of onion to use. I love onion slices on any type of beef sandwiches, burgers etc. I can't imagine using yellow onions for this purpose. Oh and chopped onion on hot dogs for me is a must. Its got to be WHITE onions which are just mild enough but without being overly sweet. Using a yellow onion to be eaten raw I'd never do. Too strong a flavor. Though for cooking Yellow onions can't be beat

Art REVIEW:
October 11, 2018Just made one for lunch at work. Can confirm that it is good. Especially if you like good, crispy onion.It's a great little veggie combo and the flavors are much more mild than you might expect. Nice alternative to the standard PBJ.In summary, definitely worth a try. You may just enjoy it!

Anonymous REVIEW:
September 24, 2016Saw this recipe and thought it sounded awful. Mentioned it to my husband and his eyes got big and he smiled and said he had these when he was a kid and loved them. So, I made him one and took a bite. Ended up making another one for myself. Lesson learned: don't knock it until you try it! It's an unusual combination but it doesn't taste like you think it will. The onion adds crunch but the peanut butter somehow keeps it from being too oniony. It's weird but good!

BananaMan REVIEW:
April 14, 2014My old man ate these when I was a kid. I wound up broke and hungry in my 20s, and had little on hand at my apartment but peanut butter, mayonnaise, and some sliced onion. I remembered him swearing up and down that the sandwiches were good. Figuring I had nothing to lose, and needing something to eat, I made one. I immediately had another. Not something I want all the time, but a vital piece of a satisfying life.

wheelingalong REVIEW:
May 13, 2011When I was young and went fishing with my dad he always made these sandwiches bu a little different, peanut butter on one slice jelly on the other slice and an onion slice (about a quarter of an inch preferably bermuda red). We looked forward to fishing with dad.

Wastelander REVIEW:
February 19, 2011I've always heard nasty things about peanut butter and onion sandwiches. I finally worked up the courage to try one and... well... it wasn't that bad. All of the ingredients blended together, and I really couldn't pick one singular flavor out. I won't be regularly eating this sandwich, but I'm not afraid to say that I've tried it and enjoyed it just a little bit.
