Grilling the onions definitely makes this taste just a little bit better! Cook time reflects chill time.

This was a really good potato salad but DH & I like a few more goodies than just onions, celery & potatoes. So next time, I'll probably add more celery, cukes, & hard boiled egg. Yes there will be a next time. Really like the flavor of the grilled onion. Enjoyed this with bean salad & a lovely thick loin lamb chop. Great meal. Thanks for a great recipe Kim, the only reason for 4 instead of 5 stars is the lack of extra goodies. Made this for ZWT5.

Loved the caramelized onion! Delicious-don't change a thing! In fact, DH had seconds which is unusual. The ratio of dressing to potato is spot on. I subbed in red wine vinegar b/c I did not have cider vinegar and used a red onion-- caramelizing it on top of stove at medium for about 15 minutes. A wonderful make ahead for a hot day! Thanks Kim127 for a keeper. Made for PRMR game.

Roasting the onion made this AMAZING. I used reduced fat mayo and skim milk to fit in with our WW points and it turned out beautifully. We also like the skin on our potatoes, so I chopped them skin on then boiled them. I also tossed in some chives from the garden. This is a favorite. We will make it again. Reviewed for ZWTIII
