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

Excellent potato salad! Who would've thought that grilling the onions would make such a difference. I added 14t garlic powder, 1.5t yellow mayo and three chopped eggs. Might have had a bit more grilled onion that I grilled on a hot skillet on the stove. If you're not in the "like mustard" group, I believe you'd love the salad anyway.

Thanks for the great potato salad recipe. I think from now on I'll always grill my onions before adding them to potato salads. That really gave it a special touch. Made for PRMR.

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.
