I am an absolute sucker for food related TV shows. We actually got cable again for the first time in years just so I could watch The Food Network. It turns out though, both YouTube and Netflix have much higher quality food content than cable. A prime example is The Chef Show with Roy Choi and Jon Favreau.

When I watched the episode "Extra Helpings with Babish and Dave," I knew that I wanted to take the plunge and make French Onion Soup from scratch. Chef Choi said that's French Onion Soup is "the easiest recipe that actually requires technique" so I thought it would be the perfect recipe to share here. On the show, he doesn't give measurements - but it gave me a great base to put together a written recipe for you guys!

Roy Choi's French Onion Soup Ingredients

If we're following this recipe to a T - there's a few layers of ingredients. It can be amped up or toned down based on your budget, time available, and desire to experiment. Basically, this soup just needs tons of onions. The traditional soup is made with onions, a hearty beef broth, liquor and cheesy toast. In a pinch, you can use chicken or vegetable broth, Chef Choi says you can even use water, but nothing will beat out a homemade beef stock. Here are some tips and tricks on what you can and can't put into stock.

For the cheesy toast, the sky truly is the limit. Ideally, you want a really nice and crusty sourdough bread, again, and as always, homemade is best. For this recipe, I didn't use homemade but I got a nice loaf of sourdough made in house at our local supermarket.

For cheeses, Roy suggests using Provolone, Emmental, Gruyere and Parmesan. I did get all of these, but I had to sub out Emmental for Swiss as none of my local supermarkets had it. Stuff like this happens - don't sweat it. However, do sweat it if you use bottled Parmesan. Ideally you want to grate it yourself. Parmesan Reggiano is my go to.

This is not a budget food, nor is it diet food. Don't think because the bulk of this dish is onions and broth that it's going to help the fat melt off your body. This is 100% comfort food. It's going to stick to your ribs and feel like the perfect meal for fall or winter.

Although this dish does require a lot of time, other than cutting onions and being patient, it doesn't require much in terms of technical skills.

After cutting all of the onions (about 5-7 of them) you just need to slowly - and I mean slowly - reduce them to what Chef Choi calls an onion jam. This recipe goes beyond caramelization for a rich and deep umami onion flavour. On The Chef Show, it looks like it only takes about 20 minutes to get the onions to where they should be, but on low-medium to medium heat, it took me about an hour and a half just to brown the onions to where they had to be.

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 - my reel of French Onion Soup here.

In The Chef Show, Roy mentions many people purposefully shortcut their caramelization 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.

Ideally, though, you left everything for the perfect amount of time and it came out flawlessly all by itself.

Ingredients

French Onion Soup

  • ¼ cup extra virgin olive oil
  • 1 tablespoon 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 tablespoon all purpose flour
  • 8 cups beef stock homemade preferred
  • 1 tablespoon worcestershire sauce optional
  • 1 tablespoon tomato paste optional

Cheese Toasts

  • 1 loaf crusty sourdough bread
  • 4 tablespoon 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

Instructions

  • 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 tablespoon 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 awhile, 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 sourdough 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 color and left a brown residue on the bottom of the pan, take 2 tablespoons 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 8 cups of beef broth. If you're not using homemade, 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.

Assembly

  • Once the soup is at the desired taste and consistency, place a serving into an oven safe bowl. Top with 1-2 slices of sourdough 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.

FAQs

How do you deepen the flavor of French onion soup? ›

My personal go-tos include worcestershire sauce, fish sauce, and brandy. Each deepens the flavor of french onion soup. Balsamic vinegar and soy sauce are other great options.

Why do you put baking soda in French onion soup? ›

The caramelized onions for this soup cook more quickly due to a pinch of baking soda but still have that deep, slow-cooked flavor. Topping the soup with hot, cheesy toasts prepared while the soup simmers, eliminates the need to bake the soup in specialty French onion soup bowls.

What is the difference between onion soup and French onion soup? ›

What is the Difference Between Onion Soup and French Onion Soup? French onion soup is always made with beef stock. Other onion soups can be made with chicken, vegetable, or beef stock. Additionally, French onion soup typically contains wine or sherry, which isn't typical or necessary in other onion soups.

Are red or yellow onions better for French onion soup? ›

Onions: You can use white, yellow or red onions for French onion soup. But to make it the classic way, you will need 5-6 large yellow onions, peeled and thinly sliced. Butter: The tastiest (French) way to caramelize those onions.

What spices add depth to soup? ›

Herbs and sources add flavor, aroma, and intensity to the soup broth. You can pick fresh or dried herbs like basil for tomato-based soups or fresh parsley for clear broths. You may also add more spices like turmeric, ground ginger, ground paprika, or nutmeg for a touch of spice and color to your soup broth.

Why do you add flour to French onion soup? ›

Onion soup, at its very essence, is nothing more than onions and water boiled together. Period, done, finished, everything added from that point on is pure opinion. Caramelizing the onions brings out sugars, and makes a more luxurious silky and sweet soup, adding flour gently thickens and provides body.

Why does my French onion soup taste burnt? ›

Yes, over high heat, onions can brown on the surface very quickly, especially in a pan that's not crowded. But the goal of caramelizing onions isn't just to brown the surface; it's to transform the onions so that they're soft and sweet to the core. Try to rush it and all you'll end up doing is burning them.

Can you use chicken broth instead of beef broth for French onion soup? ›

If you can't get good quality beef broth, use chicken or vegetable instead. I find that the quality of those by mainstream brands is much better than the beef stock. The beef is fine to use in things like gravy and stews, but not when it's a key ingredient like in this recipe.

Why do you put lemon juice in soup? ›

But as the publication explains, lemon juice adds more than just tartness. For chicken soup in particular, lemon juice balances out the more rich and savory flavors, adding an overall brightness to the taste.

What broth is French onion soup made of? ›

This soup traditionally is made with beef stock, though sometimes a good beef stock can be hard to come by and expensive to make. If you use boxed stock, taste it first! If you don't like the taste, don't use it. (If you cook a lot of beef or beef roasts, save the scraps and freeze them to make a stock with later.)

What ethnicity is French onion soup? ›

The classic French onion soup gets its name from its country of origin: France. After making its debut in the 18th century, it has become a national treasure. During ancient times (and still today), onions were cheap and easy to grow, and hence, readily available.

What kind of onion is best for soup? ›

When you are sauteing onions to build flavor as a base for your dish (soup, tomato sauce, you name it), the yellow onion is your friend. That being said, white onions are a totally acceptable substitute for yellow, especially if you're cooking them.

Should onions be caramelized for French onion soup? ›

The key to good French onion soup is to cook the onions so long that they threaten to melt into a viscous, dark brown paste, à la Marmite. As has already been extensively reported in Slate, there are no shortcuts when you're caramelizing onions; it always takes at least an hour, usually longer.

What type of bowl is best for French onion soup? ›

French onion soup is traditionally served in lionhead bowls, which are deep but not very wide porcelain bowls.

What is a substitute for vermouth in French onion soup? ›

You can substitute sweet vermouth with sherry (not sherry cooking wine) or brandy. Lillet Blanc is similar to dry white wine but more aromatic. Your favorite dry white wine is fine.

How do you doctor up canned French onion soup? ›

Infusing the soup with a richer taste is as easy as quickly sauteing crushed garlic before pouring the soup in. Some soft, buttery garlic sauteed in earthy olive oil is the perfect addition to enrich canned French onion soup.

How do you make soup taste stronger? ›

Use fresh vegetables, high-quality meats or broth, and fresh herbs to add depth of flavor. Add acidity: A squeeze of lemon or lime juice, a dash of vinegar, or a splash of wine can brighten the flavors of a soup and make it taste more complex.

How do you get the depth of flavor in vegetable soup? ›

A squeeze of citrus, a dollop of yogurt or a drizzle of cream, a dusting of cheese or a good chile powder, a sprinkling of some herbs or croutons — all can take a perfectly fine soup into the realm of the delectable. Even a spiral of good olive oil to finish and some coarse sea salt can do wonders.
