Ingredients

The beauty of this french onion soup recipe lies in its short ingredient list. Each item plays a crucial role in building layers of flavor.

  • 3 tbsp (42g) butter
  • 4 large yellow onions, peeled and sliced thinly in half rounds
  • 2 garlic cloves, peeled and minced
  • ¼ tsp salt
  • 8 cups (2L) beef broth
  • 1 cup (250ml) additional beef broth (for deglazing)
  • 3 to 4 sprigs fresh thyme
  • ½ tsp freshly ground black pepper
  • 200g day old baguette (or country bread)
  • 3 tbsp (45ml) extra virgin olive oil
  • ¼ tsp salt (for croutons)
  • ¼ tsp black pepper (for croutons)
  • 1 cup (100g) Gruyère cheese, grated

Let us talk about the onions for a moment. Yellow onions are the standard choice here because they have a great balance of astringency and sugar. As they cook down, those natural sugars caramelize, creating the base flavor of the soup. You could use sweet onions, but yellow ones tend to offer a deeper, more complex savory note that balances the saltiness of the broth.

For the bread, a day old baguette is ideal. Fresh bread is often too soft and can turn into mush when it hits the liquid. Stale bread has a firmer structure that acts like a sponge, soaking up the broth while still holding its shape under the heavy layer of broiled cheese. If you only have fresh bread, you can dry it out in the oven for a few minutes before cubing it.

Step-By-Step Instructions

Follow these steps to create a warming bowl of soup that rivals any restaurant version. Patience is your best friend here.

Step 1: Caramelize the Onions

Start by placing a large, heavy bottom pan over heat that is between medium and low. Add 2 tablespoons (28g) of the butter to melt. Once the butter is bubbling slightly, add your thinly sliced onions, the minced garlic, and the salt. Stir everything gently to coat the onions in the butter.

Now comes the most important part. Cook the onions gently, stirring every 5 to 10 minutes. You want them to turn a deep golden brown color. Do not rush this step. It can take anywhere from 40 to 60 minutes for the onions to fully caramelize. About halfway through the process, add the remaining 1 tablespoon (14g) of butter. This adds richness and helps the caramelization process along. The onions should reduce significantly in volume and become very soft and sweet.

Step 2: Deglaze the Pan

Once your onions are beautifully caramelized, it is time to deglaze. Pour in the 1 cup of additional beef broth. As the liquid hits the hot pan, use a wooden spoon to scrape up any browned bits stuck to the bottom. These bits are called fond, and they are packed with concentrated flavor. Turn the heat up to medium and let the liquid simmer until it reduces by about half. This concentrates the flavor even more.

Step 3: Simmer the Soup

Add the main 8 cups (2L) of beef broth to the pot along with the black pepper and the fresh thyme sprigs. Bring the mixture to a slow boil. Once it reaches a boil, turn the heat down to between medium and low again. Let it simmer uncovered for 1 hour. This long simmer allows the flavors of the onions, thyme, and beef broth to meld together perfectly. After the hour is up, taste the soup and add more salt and pepper if you think it needs it.

Step 4: Make the Croutons

While the soup is simmering, preheat your oven to 350°F (180°C) and place a rack in the middle position. Line a baking sheet with foil for easy cleanup. Cut your bread into half inch cubes. In a bowl, toss the bread cubes with the olive oil, salt, and pepper until they are evenly coated.

Spread the bread cubes out on the prepared baking sheet in a single layer. Bake them for 10 to 13 minutes. You want them to be crisp and golden brown. Once they are done, remove them from the oven and let them cool on a rack. They should be very crunchy so they can stand up to the soup.

Step 5: Assemble and Broil

When you are ready to serve, remove the thyme sprigs from the soup pot and discard them. Ladle the hot soup into oven safe bowls. Set your oven to broil. Top each bowl with a generous handful of your homemade croutons. Then, cover the croutons with ¼ cup (25g) of grated Gruyère cheese per bowl.

Place the bowls on a baking sheet to catch any drips and slide them under the broiler. Watch them closely. Broiling takes only 1 to 2 minutes at most. You want the cheese to be melted, bubbly, and slightly browned in spots. Serve immediately while it is hot and gooey.

How To Store Leftovers

If you have leftovers, you are in luck because this soup tastes even better the next day. Allow the soup to cool completely before transferring it to an airtight container. It will stay fresh in the refrigerator for up to 3 or 4 days. The flavors will continue to develop as it sits, making for a delicious lunch.

You can also freeze the soup base. Store the soup without the bread or cheese in a freezer safe container for up to 3 months. When you are ready to eat, thaw it in the fridge overnight and reheat it on the stove. Make fresh croutons and add fresh cheese right before serving for the best texture. Do not freeze the soup with the bread and cheese already added, as it will become soggy and unappetizing.

Tips

To ensure your french onion soup recipe turns out perfectly every time, here are a few helpful pointers. First, slice your onions consistently. If some slices are thick and others are paper thin, they will cook unevenly. You want them all to caramelize at the same rate. A mandoline slicer can be very helpful for this, but a sharp knife and a steady hand work just fine too.

Another tip is to grate your own cheese. Pre grated cheese often contains anti caking agents that prevent it from melting smoothly. For that classic, stretchy cheese pull, buy a block of Gruyère and grate it yourself. It makes a huge difference in the final texture of your Baked French Onion Soup.

Finally, do not skimp on the broth quality. Since broth makes up the majority of the liquid volume, its flavor is paramount. If you can use homemade beef stock, that is amazing. If you are using store bought, look for a high quality, low sodium variety so you can control the salt level yourself. This ensures your soup does not become overly salty as it reduces.

Conclusion

Making this french onion soup recipe at home is a rewarding experience that yields delicious results. It transforms humble ingredients into a luxurious meal that warms you from the inside out. Whether you are cooking for yourself or hosting a dinner, this dish is sure to impress. It captures the essence of comfort food without requiring complicated techniques or hard to find ingredients. So grab a bag of onions and get cooking. Your kitchen will smell amazing, and your taste buds will thank you.

FAQ

Can I Make This Gluten Free?

Yes, absolutely. The soup base itself is naturally gluten free if you check your beef broth ingredients to ensure no hidden gluten is present. To make the full dish safe, simply swap the baguette for a gluten free bread option. Cube it and toast it just like the regular recipe instructions state.

Can I Use a Different Cheese?

While Gruyère is the traditional choice for a Copycat French Onion Soup, you can certainly use substitutes. Swiss cheese or Emmental are excellent alternatives that melt beautifully. Provolone or Mozzarella can work in a pinch if you want that stretch, though the flavor profile will be milder.

How Does This Compare to Ina Garten French Onion Soup?

Recipes like the Ina Garten French Onion Soup or the Joy Of Cooking French Onion Soup are iconic, but they often use wine or brandy. This recipe keeps things simpler and alcohol free by using beef broth for deglazing. It is lighter but still packs a massive savory punch, making it a great alternative for families.

Can I Scale This Down for a French Onion Soup For Two?

Yes, this recipe scales down very easily. Simply halve all the ingredients. However, keep in mind that caramelizing a smaller batch of onions might take slightly less time, so watch the pan closely. It is the perfect romantic meal if you are looking for a French Onion Soup For Two.

What If I Want to Use Wine?

If you prefer a French Onion Soup Recipe With Red Wine or even a French Onion Soup With Cognac, you can easily adapt this. Simply replace the 1 cup of additional beef broth used for deglazing with 1 cup of dry red wine or a splash of cognac mixed with broth. The method remains exactly the same.
