Classic French Onion Soup Recipe

Enjoy my signature soup the way my granddaughter Becky does. I make it for her in a French onion soup bowl complete with garlic croutons and gobs of melted Swiss cheese on top. —Lou Sansevero, Ferron, Utah

"Real French Onion flavor- better than most restaurants! I used red wine instead of port, and did a lot of tasting for my personal tastes. I only used 5-6 onions, which was plenty. I had only Swiss cheese and it was still very, very good. I'll definitely make it again to share with my family."

"I love French onion soup and this was the most delicious recipe for this soup. I used sherry instead pf port wine and it was perfect. I eye balled all the engredients for 5 people and it came out very tasty for my first try. Next time I will use Gruyere cheese instead of Swiss and I'm sure it'll be better than perfect!!! Thank you for sharing your recipe!"

"Yummy. One tip, if you don't have an oven safe bowl, toast the bread as directed and before removing from the oven, place the cheese on top of the bread and heat or broil till melted and slightly browned and then place on top of the soup in your regular bowl."

"Great soup with great flavor. I have made this once before and am doing it again today. I picked this recipe after searching through a lot of others, this was by far the simplest and least time consuming but the flavor is so rich and deep! The first time I followed all the directions exactly and just didn't care for the port, I thought it over powered. This time I used a favorite wine of mine and it was spot on perfect. Added extra onions, broth, butter, and wine this time so I will have plenty left to can. Thanks for a great recipe."

"Made th is for lunch yesterday and it had a very nice flavor, but i would have left out the wine, and used half mozarella and half Swiss.

My mother in law liked the soup, but thought the cheese was a little rubbery."
