Instead of being battered and deep-fried, this onion is brushed with melted butter and mustard, sprinkled with bread crumbs and seasonings and baked. It's an impressive-looking appetizer, and the dip can be used for veggies and crackers, too. —Kendra Doss, Kansas City, Missouri

"Onion was good. Tender with good flavor. Loved the easy prep. Add the horseradish to the sauce as others recommend, and I agree it is a necessity. If you are looking for a duplicate of the fried variety, you may be disappointed. But overall, I enjoyed it and will make again."

"We also liked pulling all the segments apart after the first 20 minutes and coating all the onion slices with the mustard/butter mix and then sprinkling with the topping (of which we used Amaranth Cereal Flakes for a g/f version). It was easier to get the portions on plates for sharing."

"This was fabulous! I will make it again and again. I never thought I'd be able to really enjoy a blooming onion without the guilt, but this was delicious! I did however use regular sour cream and panko crumbs as it's what I had on hand. I will definitely make sure I have fat free sour cream on hand for this in the future. The only thing that I added to the sauce was horseradish, as I like it spicy...just a personal preference. Thanks for a wonderful recipe!!"
