French Onion Pizza au Gratin Recipe

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

"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.
