French Onion Pizza au Gratin

I love a hot bowl of French onion soup and am also a fan of pizza after busy workdays. This recipe combines classic onion soup ingredients with everyday pizza staples. —Bonnie Long, Lakewood, Ohio

    All my favorite flavors in the world and I found it very underwhelming. Did not feel the flavors mixed well. I love French Onion Dip from the store but couldn't find any so made it myself with Lipton's Golden Onion Soup mix and maybe that was the problem, or maybe the brown sugar in the caramelized onions altered the wonderful taste of caramelized onions?

    This pizza was fantastic. I dont like onions but wanted to try it because my husband loves onions. I used a red onion and the flavor was so sweet and zesty. We also made a homemade pizza crust. Would eat this once a week if I could!!

    We apologize for omitting the baking temp in this recipe. It will be corrected here soon. The pizza should be baked at 425 degrees for 10-15 minutes.Taste of Home Test Kitchen

    I'm making this for the super bowl & the recipe does not have an oven temp.
