Roy Choi French Onion Soup Recipe Ingredients

French Onion Soup

  • 1/4 cup extra virgin olive oil
  • 1 tbsp bacon fat
  • 6 onions yellow or spanish
  • 2 bay leaves
  • 1 sprig thyme
  • salt
  • pepper
  • 2 tbsps butter unsalted
  • 3 oz brandy beer or sherry works, too
  • 2 tbsp all purpose flour
  • 8 cups beef stock homemade preferred
  • 1 tbsp worcestershire sauce optional
  • 1 tbsp tomato paste optional

Cheese Toasts

  • 1 loaf crusty sourdough bread
  • 4 tbsp extra virgin olive oil
  • 1 clove garlic
  • 6 slices provolone cheese
  • 6 slices emmantel cheese or swiss cheese
  • 6 slices gruyere cheese
  • 3 oz parmesan cheese freshly grated


  • Place the olive oil and bacon fat in a large saucepan. Bring up to heat over medium. Once hot, place onions in the pot and simmer until slightly warmed. Generously add salt and pepper (about 1 – 2 tbsp each) and stir until combined.
  • Add in the 2 tablespoons of butter to the onions, stir to mix. Add in the thyme and bay leaves. Keep the heat over medium-low and simmer until translucent. This will take a while, upwards of an hour and a half depending on your stove.
  • While you’re waiting for the onions to caramelize, slice up a loaf of sour dough bread and coat it generously with olive oil. Preheat the oven to 350 degrees and bake until browned (about 15 minutes). Flip half way through the cooking time. Set aside to cool.
  • Once the toast is cool enough to touch, take a peeled clove of garlic and gently rub it on each side of the toasts. Set aside.
  • Once the onions have reduced significantly, turned a deep brown colour, and left a brown residue on the bottom of the pan, take 1 tablespoon of flour to coat the onions. Then, add in 3 ounces of brandy and deglaze the pan. Let the onions absorb the brandy and cook until evaporated.
  • Add in 6 cups of beef broth. If you’re not using home made, or just want extra depth of flavour, add in 1 tablespoon both of worcestershire sauce and tomato paste. Simmer for another 10 – 15 minutes, until thickened and slightly reduced.


  • Once the soup is at the desired taste and consistency, place a serving into an oven safe bowl. Top with 1-2 slices of sour dough toast, and then layer the cheeses (gruyere, emmantel, provolone, and parmesan) and return it to the 350 degree oven to bake until the cheese is melted and the soup is bubbling at the sides.
  • If the cheese doesn’t get the desired texture, you may broil it for an additional minute or two. Make sure to watch it closely, so it doesn’t burn.

How To Make Roy Choi’s French Onion Soup?

While I was simmering down the onions, I actually took time to write out this recipe as well as make my first Instagram Reel! I never got into the whole TikTok trend, so I feel like I’m just playing catch up with reels. It was kind of cool and turned out interesting – here’s my reel of French Onion Soup here In The Chef Show, Roy mentions many people purposefully shortcut their caramelisation with additives. What happens if you accidentally under caramelize your onions? In the ingredients list, I’ve added 2 “optional” ingredients if you find your broth wasn’t rich enough, or your onions didn’t caramelize long enough. They’re either (or both of) tomato paste and Worcestershire sauce. If you need an umami boost, adding either or both of those ingredients will hack your soup if you were impatient or overestimated the quality of your broth.

Roy Choi French Onion Soup Recipe Tips from Readers

Having made French onion soup on a number of occasions, I have a few tips.

1. Homemade beef stock. I can’t emphasize this enough. The store-bought stuff is fine in a pinch, but for something decadent like this soup, it has to be made from scratch.

2. As mentioned up thread – be patient with the onions. It takes an hour to properly caramelize onions. The more the merrier when it comes to onions. 8 large onions seems like a ton when it barely fits in the pot, but after an hour it’s amazing how much it reduces down.

3. After the onions reduce down I add a pint of bourbon, 1/3 at a time. The 1st 2/3 I completely evaporate into the onions. The final 1/3 I mostly evaporate but do leave a little bit of liquid.

4. Gruyere cheese. It’s expensive as heck but it really makes a difference as opposed to, say, Swiss cheese.

Typically I’ll make the soup a couple of days ahead of time and will refrigerate it. Then, reheat it in the microwave, plop the large crouton (I like sourdough that I’ll dry out in the oven after brushing it with olive oil and seasoning it) into an oven-safe bowl. Pour in the soup and top it with Gruyere cheese. Put the bowls on a baking sheet and put it in the oven and crank the broiler. Once the cheese melts and takes on some color you are all set.

Once you’ve had no-corners-cut homemade French onion soup you’ll find it very hard to ever order it at a restaurant again.
