French Onion Soup
Recipe
Hearty and comforting, French onion soup is a classic dish that has stood the test of time. The key to its rich, complex flavor lies in the slow caramelization of the onions, which gives the broth its deep, sweet essence. Topped with crusty bread and melted cheese, this soup is the ultimate indulgence on a chilly day. There are many variations of the French onion soup recipe, with some adding a splash of red wine or a sprinkle of fresh herbs for added depth of flavor. Regardless of the specific ingredients used, the process of slowly cooking the onions until they are deeply golden brown is essential for achieving the soup’s signature taste. Whether enjoyed as a starter or a main course, a steaming bowl of French onion soup is sure to warm the soul and tantalize the taste buds.
Preparing this dish requires a bit of time and patience, but the end result is well worth the effort. The process of coaxing out the natural sugars in the onions is a labor of love, but the reward is a soup that's truly elevated beyond the sum of its parts.
Ingredients:
- 6 large yellow onions, sliced
- 4 tablespoons unsalted butter
- 2 tablespoons olive oil
- 3 cloves garlic, minced
- 1/2 cup dry white wine
- 6 cups beef or chicken broth
- 2 sprigs fresh thyme
- 1 bay leaf
- Salt and freshly ground black pepper, to taste
- 1 baguette, sliced
- 1 1/2 cups grated Gruyère cheese
Instructions:
In a large pot or Dutch oven, melt the butter and olive oil over medium-low heat. Add the sliced onions and cook, stirring occasionally, until deeply caramelized and reduced, about 45-60 minutes.
Be patient and allow the onions to slowly brown, as this is the key to developing the soup's rich, sweet flavor. Add the garlic and cook for an additional 2-3 minutes until fragrant.
Deglaze the pot with the white wine, scraping up any browned bits from the bottom. Allow the wine to reduce by half. Pour in the broth, then add the thyme and bay leaf. Season with salt and pepper.
Simmer the soup for 30 minutes, allowing the flavors to meld.
Tips:
For the best texture and flavor, be sure to slice the onions thinly and evenly. This will help them caramelize more quickly and evenly.
When adding the cheese, you can either top individual bowls of soup with the bread and cheese, or you can place the baguette slices on a baking sheet, top with the cheese, and broil until melted and bubbly before adding to the soup.
Serve the soup immediately, as the cheese topping can become soggy if left to sit for too long.
Cooking Steps
Slice those onions thinly and evenly to get them just right.
Next, caramelize the onions over medium heat until they're golden brown and delicious.
Now, add the beefy broth and let the flavors meld together.
Top it all off with crispy croutons and melty cheese, then pop it under the broiler until that cheese is perfectly melted.
Step 1. Slice Onions Thinly and Evenly
Thinly slicing the onions is crucial for achieving the perfect texture and flavor in your French onion soup. Take your time and work carefully to ensure each slice is uniform in thickness. This will help the onions caramelize evenly, creating a rich, sweet base for the soup.
Use a sharp knife and slice the onions from pole to pole, cutting across the grain. This will result in thin, delicate slices that will melt into the broth. Aim for slices about 1/8 to 1/4 inch thick. If the onions are too thick, they won't soften and caramelize properly. Conversely, if they're too thin, they may burn or become mushy.
As you slice, try to maintain a consistent thickness throughout. This will guarantee each bite of the finished soup has the same wonderful balance of flavors and textures.
With a little practice, you'll be an expert onion slicer in no time, ready to craft the most delectable French onion soup.
Step 2. Caramelize Onions Over Medium Heat
Once you've finely sliced the onions, go ahead and start cooking them over medium heat. You'll want to get those onions sizzling!
Grab a large pot or Dutch oven and add a few tablespoons of olive oil or butter. Let it heat up until it's nice and hot. Then, toss in all your sliced onions. Don't worry if the pot looks full – the onions will cook down quite a bit.
Now, keep the heat at medium and let the onions cook, stirring occasionally. You'll notice they start to soften and turn translucent.
As they cook, the natural sugars will begin to caramelize, giving the onions a rich, golden-brown color and delicious, sweet flavor. This process can take 30-45 minutes, so be patient and let them do their thing.
Keep an eye on them, though, and adjust the heat if they start to brown too quickly. The key is slow, even caramelization for the best tasting French onion soup.
Step 3. Add Beef Broth
After you've caramelized the onions to perfection, it's time to add the beef broth. Pour in the broth, making sure to scrape up all the flavorful bits from the bottom of the pan.
The beef broth will immediately begin to sizzle and steam as it hits the hot onions. This is where the magic really starts to happen!
Stir the broth gently, allowing the onions to absorb all those rich, savory flavors. As the liquid simmers, you'll notice the onions softening even further, becoming melt-in-your-mouth tender.
The broth will slowly take on a deep, golden hue, transforming into the perfect base for your French onion soup.
Keep a close eye on the pot, adjusting the heat as needed to maintain a gentle simmer. Allow the broth to reduce slightly, concentrating the flavors.
This process should take about 10-15 minutes, filling your kitchen with the most tantalizing aroma. Soon, you'll be ready to move on to the next step: adding the toasted bread and gooey cheese!
Step 4. Add Croutons and Cheese
Next, place the toasted bread slices on top of the simmering broth. This'll allow the croutons to soak up all that delicious beefy flavor.
Once the bread is floating on the surface, sprinkle a generous amount of shredded cheese over the top. You'll want to use a melty cheese like Gruyère or Swiss.
As the soup heats up, the cheese will start to melt and get all gooey and irresistible. Give it a minute or two, then watch as the cheese turns golden brown and bubbly on top.
The croutons will get soft underneath, creating the perfect contrast of textures.
Now you're ready to serve! Ladle the cheesy, crouton-topped soup into bowls and enjoy.
The combination of the savory broth, caramelized onions, toasted bread, and melted cheese is absolutely heavenly. Get ready for oohs and aahs from your family and friends!
Step 5. Broil Until Cheese Is Melted
Place the bowls of soup with the bread and cheese topping under the preheated broiler. Watch as the cheese begins to bubble and melt, transforming into a golden-brown crust. The aroma of the caramelized onions and melted cheese will fill the air, making your mouth water in anticipation.
Carefully monitor the bowls, ensuring the cheese doesn't burn. Use the broiler's high heat to your advantage, allowing the cheese to melt and become irresistibly gooey. As the cheese melts, it'll slowly cascade down the sides of the bowl, creating a delightful mess.
Once the cheese is perfectly melted and bubbly, remove the bowls from the broiler. Be cautious when handling the hot bowls, and remember to use oven mitts or a towel.
Serve the French onion soup immediately, allowing your guests to enjoy the warm, comforting flavors. The combination of the caramelized onions, savory broth, and melted cheese is sure to delight your taste buds and warm your soul.
