Ingredients

Directions

  • Heat oil in a large, heavy pot over medium. Add onions and cook, stirring occasionally, until soft and beginning to turn golden, 35 to 40 minutes (if onions develop color quickly, reduce heat).

  • Add butter, garlic, thyme, bay leaf, 2 teaspoons salt, and 1/4 teaspoon pepper. Cook, stirring a few times, until golden brown, 15 to 20 minutes more. Add vermouth and boil, scraping up browned bits from bottom of pot, until mostly evaporated, 1 to 2 minutes.

  • Stir in stock and Marsala. Bring to a boil, then reduce heat to low and gently simmer 45 minutes. Season to taste.

  • Preheat broiler. Ladle soup into broiler-safe crocks or bowls set on a rimmed baking sheet. Nestle a piece of toast into each, partially submerged, and top each with 1/3 cup Gruyère. Broil until cheese is melted, bubbly, and golden brown in places, 2 to 4 minutes. (Soup without toast and cheese can be cooled and refrigerated in an airtight container up to 3 days, or frozen up to 6 months.)

Fabulous recipe. Tastes exactly like the French onion soup at Au Pied de Cochon in Paris.

Thank You Martha !! This is a great soup. I've made it a few times making small changes such as less sherry, adding Port instead of sherry but the original is great. Also, thanks for the tip on dutch ovens, it's my go to pan. Love the cast iron with the porcelain coating !!! You are a great cook !!!!!

I made this for dinner, the only change I made was using Vermouth instead of the sherry. It came out wonderful! I didn't have to buy a baguette as I had some day old bread I had made that was perfect to use in this recipe.

Not good; sweet to the extreme. Throwing out the broth and onions; husband and I cannot eat this. Caramelized onions have their own natural sweetness - I should have listened to my first instincts when I read this recipe and left out the teaspoon of sugar and the sherry. Also, will double the cheese on top. I am using dedicated French Onion bowls which look quite a bit larger than the ones shown in the picture - maybe that is why there was only a thin spattering of cheese on top.

I make this with a few modifications: - more butter (about 1.5 sticks) -instead of sherry use a zin or cab - stock can be vegetable or turkey/ chicken - add reduced balsamic vinegar instead of sugar (about .25 cup) -1/2 tsp minced garlic Love. Definitely think gruyere cheese is the way to go. It's a distinct difference.

I added extra tea.s sugar and that really ruined the taste. But after fixing it it tasted really really great. I added half a cup flour and that really helped with the color and flavor. didn't use dried cherries. I will absolutely make it again with more flour, less sugar and no cherries. I might try to make it more creamy to match my family taste maybe adding milk and cream will do it.

I saw her make this on the show and thought I would make it, but as a severely altered version cause I didn't have most ingredients, I didnt use wine or cooking sherry, i made my own so called broth using the water, 4 restaurant packets of soy sauce, 1 pack of chicken bullion from oodles of noodles and a splash of vinegar, I only had bay leaves and dries basil.... and used mozerella cheese also. It tasted great & is a yummy comfort food! I may skip the sugar on the onions next time though.

This soup is near perfect. I cut down a little on the sherry (used xtra dry), and instead of thyme, added a cheesecloth satchel of herbs de provence for seasoning and a bay leaf (if I had fresh thyme I'd have used that). A nice rustic baguette with a firm crust works best. Gruyere melts great but if you're on a budget a good quality swiss will work almost as well. Delish!

Made it. It was really good. I used a mixture of mozz, white cheddar and swiss as my family is not big on swiss. I used a bagguette for the bread. My onions were pretty sweet so I would have like it to be a little more savory.

IS THERE ANY TYPE OF NON-ALCOHOLIC SUBSTITUTE FOR THE SHERRY - WE DO NOT CONSUME ANY ALCOHOL - BE IT FOR COOKING OR DRINKING???

I made this soup last night for myself and a friend and we were both blown away! It is fantastic! And so easy too. I did cook the onions for one hour and had great flavor. I will try the balsamic vinegar next time.

MMMmmm....this is a classic - so easy too. Even better homemade. I find that the onions are caramellized enough in about 30 minutes so don't let the hour for cooking the onions deter from making this. I'm sure its wonderful after an hour, but it's tough on a week night! Adedoyina - not sure if you're looking for non alcoholic sub, but you can use white wine (sauvignon blanc is good) or a dry red wine in place of the sherry. The sherry is delicious though.

Jessiekaye - your idea for adding balsamic vinegar and maple syrup sounds wonderful, but exactly how much of each? I have never made this soup before, but it is my 8 year old daughter's favorite, so I would like to make it for her. Have you ever been to Paris? (your vacation preference...) I went to college there and lived there for a year. It really is as special as you expect. Thank you for your time and for sharing.

If you want them to taste like magic, yes, that is really how long it takes. It's true that a low heat and longer cooking time improves the taste of the onions. When making this soup, I also like to add a few cloves of garlic, and prefer to use a little balsamic vinegar and maple syrup instead of basic sugar. Happy souping!!

One hour to carmelize onions seems a lot. Is that really how long this takes?
