You’ve probably seen a thousand recipes for French onion soup. Most of them tell you to stand over a stove for two hours, sweating over onions until they reach a deep, dark mahogany that looks more like coffee than vegetables. Then they tell you to deglaze with expensive cognac and simmer beef bones for half a day. It’s a lot. Honestly, it’s enough to make you just order the canned stuff and call it a night.
But then there’s french onion soup jacques pepin style.

If you know Jacques, you know he doesn’t do "fussy" just for the sake of it. He’s the king of economy in the kitchen. When he makes his Soupe à l’Oignon Gratinée, he breaks the rules that food bloggers treat like scripture. He’s not using beef stock. He’s not caramelizing onions for three hours. And yet, it might be the best thing you’ll ever eat on a Tuesday night.
The Chicken Stock Rebellion
Here is the first thing that catches people off guard: Jacques Pépin usually uses chicken stock.
Most "authentic" guides insist on a rich, dark beef consommé. They say it’s the only way to get that signature depth. Jacques basically shrugs that off. He argues that a good, homemade chicken stock—or even a high-quality low-sodium store-bought one—provides a cleaner base that doesn't mask the flavor of the onions.
Chicken stock is lighter. It’s brighter.

When you use beef stock, you’re often tasting the cow. When you use chicken stock in your french onion soup, you’re actually tasting the onions. It’s a subtle shift that makes the whole bowl feel less like a heavy lead weight in your stomach and more like a proper meal.
Why 15 Minutes is Enough
Let’s talk about those onions. The internet will tell you that if you don't cook onions for 45 minutes to an hour, you've failed. Jacques? He often does them in about 15 minutes.
He uses a mix of butter and a dash of oil. He cranks the heat to medium-high. He’s not looking for a slow, sugary breakdown; he’s looking for a "nicely brown" color. He wants the onions to retain a bit of their soul.
- The Cut: He slices them coarsely. Not paper-thin.
- The Color: Golden-brown, not black.
- The Texture: They should be soft but not complete mush before the liquid hits the pan.
He also mentions his mother’s technique—Maman’s way—which involved browning the onions heavily, then adding a little flour and water. It’s the ultimate "peasant" version. No fancy stock required, just the magic of a well-seared onion and some tap water. It proves that this dish isn't about luxury; it’s about what you can do with a bag of cheap produce.
The Secret Lyonnaise Twist
If you really want to go deep into the lore, you have to look at the "Lyonnaise-style" version Jacques describes from his youth. Back when he was a young man in Lyon, he and his friends would head to a restaurant at 2:00 or 3:00 AM after a night of dancing.
They didn't just eat the soup. They transformed it.
They would bring a massive tureen of soup to the table, already covered in a thick crust of cheese. Then, they’d take a couple of egg yolks and a healthy splash of Port wine. They’d whip them together, poke a hole in the center of the cheese crust, and pour the mixture right in.

They’d stir the whole thing up—the bread, the melted cheese, the yolks, and the wine—until it became a thick, unctuous, messy "panade." It looks like a disaster. It tastes like heaven. Most people don't talk about this version because it’s not "pretty" for Instagram, but it’s the real-deal soul food of Jacques’ childhood.
Building the Gratinée
The word "gratinée" is key. Without it, you just have onion soup. To make it a gratinée, you need the crust.
Jacques is specific about the bowl. He loves a bowl with a little "lip" on the edge. Why? Because when you place your toasted baguette slices in there, the bread catches on the lip. Then, when you pile on the cheese, it sticks to the sides and creates a structural seal. This prevents the bread from sinking to the bottom and turning into a soggy sponge immediately.
He uses a lot of cheese. Like, a lot.
- Gruyère is the classic choice.
- Emmentaler or a good Swiss also works.
- Comté is another great option if you want something nuttier.
He’ll often put some cheese at the bottom, add the bread, pour the soup, and then bury the top in more cheese. Then it goes into a 400°F oven for about 20 to 30 minutes. Most people just use the broiler for 2 minutes. Jacques prefers the bake. It allows the flavors to meld and the cheese to actually brown and develop a "skin" that is chewy and crispy at the same time.
What You Can Do Right Now
You don't need a culinary degree to pull this off. Honestly, you just need a few onions and some patience. If you want to try the french onion soup jacques pepin way tonight, here is the move:
- Don't overthink the stock. If you have chicken stock in the pantry, use it. Don't run to the store for beef bones unless you really want to.
- Toast your bread hard. You want that baguette to be like a rock before it hits the liquid. If it’s soft, it’ll disintegrate.
- Be aggressive with the cheese. Press some of it against the rim of the bowl. That burnt, crispy cheese on the edge of the ceramic is the best part.
- Try the Port and Egg trick. If you’re feeling bold, whisk an egg yolk with some Port wine and stir it into your bowl at the very end. It changes the texture entirely.
This soup is meant to be a full meal, usually served with a simple green salad and maybe a glass of red wine. It’s humble, it’s relatively cheap, and it’s a masterclass in how simple techniques beat expensive ingredients every time.
Next, you could try making your own chicken stock from scratch using Jacques' method of simmering chicken backs and necks with herbes de Provence to really elevate the base of your next batch.
