Ingredients Needed

Let’s break down what you’ll need to bring this recipe to life. These ingredients are easy to find and don’t require a lot of fancy prep-just quality, fresh ingredients that speak for themselves.

Yellow onions (5 large) – The star of the show! You want sweet, mild yellow onions that will caramelize beautifully and provide that signature sweet-savory base.
Beef (1 pound) – Beef chuck, brisket, or stew meat works best. You want something that will hold up during the slow cooking process and infuse the broth with its rich flavor.
Beef broth (4 cups) – This is the backbone of your soup. Look for high-quality, low-sodium beef broth or make your own from scratch if you’re feeling ambitious.
Butter (3 tablespoons) – For sautéing the onions and beef, butter adds richness and depth.
Olive oil (2 tablespoons) – For browning the beef and onions.
Dry white wine (1 cup) – This is used to deglaze the pan after browning the beef and onions. It adds acidity and helps lift all those wonderful flavors off the bottom of the pot.
Garlic (3 cloves, minced) – Garlic always adds depth and a fragrant aroma that elevates the overall flavor of the soup.
Thyme (1 teaspoon) – Fresh thyme, if possible. The earthy flavor complements the beef and onions so beautifully.
Bay leaves (2) – These add a subtle, aromatic quality to the broth.
Salt and pepper (to taste) – Essential for seasoning the dish at every stage.
Baguette (1) – The perfect vessel for your soup’s topping. You’ll toast it and use it to hold the melted cheese.
Gruyère or Swiss cheese (1 ½ cups, shredded) – This melty, gooey cheese is the crowning glory of French onion soup, offering a rich, nutty flavor.

Cooking Instructions

Now that you’ve gathered all your ingredients, it’s time to get cooking. Here’s how to craft this hearty, soul-warming soup step by step:

Caramelize The Onions
- Start by slicing the onions thinly. The thinner the slices, the better they’ll caramelize.
- In a large, heavy-bottomed pot (like a Dutch oven), melt 2 tablespoons of butter with the olive oil over medium heat.
- Add the onions and cook them low and slow, stirring occasionally, until they turn a deep golden brown. This will take about 30-40 minutes, but be patient-the more you caramelize them, the more flavor you develop.
Brown The Beef
- While the onions are caramelizing, season the beef with salt and pepper. Cut the beef into bite-sized chunks.
- In a separate pan, heat the remaining tablespoon of butter over medium-high heat and brown the beef in batches. You want a nice sear on the outside to bring out those rich, beefy flavors.
- Once browned, set the beef aside.
Deglaze The Pot
- After the onions are perfectly caramelized, pour in the dry white wine to deglaze the pot. Scrape up any fond (the crispy, flavorful bits stuck to the bottom of the pan) with a wooden spoon.
- Let the wine cook for 2-3 minutes, reducing slightly.
Combine The Broth & Herbs
- Add the browned beef, beef broth, minced garlic, thyme, and bay leaves to the pot with the onions. Stir everything together.
- Bring the mixture to a simmer, then reduce the heat and let it cook for at least an hour, allowing the flavors to meld and the beef to become tender. You can even cook it longer (up to 2 hours) for even more depth of flavor.
Prepare The Toasted Baguette
- While the soup simmers, slice the baguette into 1-inch slices. Toast them in a 375°F (190°C) oven for about 10 minutes or until crispy and golden.
Assemble The Soup
- Ladle the soup into oven-safe bowls, topping each with a slice or two of toasted baguette.
- Sprinkle a generous amount of grated Gruyère or Swiss cheese over the bread, then place the bowls under the broiler for 2-3 minutes or until the cheese is melted and bubbly.
Serve
- Let the bowls cool for a minute or two, and then serve the soup hot. The cheesy, toasted bread should be delightfully crisp on top, while the soup underneath remains warm and flavorful.

Ingredient Insights

Let’s take a closer look at some of the key ingredients in this recipe and why they matter:

Yellow Onions: These onions become sweeter as they cook, making them perfect for this dish. Caramelizing them over low heat brings out their natural sugars and deepens the flavor of the soup.
Beef: The beef adds richness and a savory depth that complements the sweet onions. You can use beef chuck, brisket, or stew meat, but whichever you choose, make sure it’s a cut that will hold up in a long simmer.
Beef Broth: The beef broth is essential for creating a deep, meaty flavor base. Opt for a low-sodium broth to control the seasoning yourself, or make your own if you’re looking for that extra homemade touch.
Gruyère Cheese: This Swiss cheese has a nutty, slightly sweet flavor that’s perfect for French onion soup. When it melts, it creates that golden, gooey topping we all know and love.

Expert Tips

To truly elevate your French Onion Soup Beef recipe, here are a few expert tips:

Low and Slow for Caramelization: Don’t rush the onions. The longer you caramelize them, the more complex and sweet their flavor will become. Stir occasionally and keep the heat low to avoid burning.
Use a Mix of Broths: For a more layered flavor, try using a combination of beef broth and a little bit of chicken broth. The chicken broth adds a lightness that complements the richness of the beef.
Make It Ahead: French onion soup tastes even better the next day as the flavors continue to develop. If you have the time, make it a day ahead and reheat when ready to serve.
Toast the Bread Just Right: Be sure to toast the baguette slices until they’re golden and crisp but not overly hard. The bread needs to be sturdy enough to support the cheese but still soak up some of the soup.

Recipe Variations

Looking to switch things up? Here are some fun variations to try:

Add Mushrooms: Throw in some sliced mushrooms when caramelizing the onions. The earthy flavor of the mushrooms pairs beautifully with the sweet onions and rich beef broth.
Add Herbs: Besides thyme and bay leaves, try experimenting with fresh rosemary or sage for added fragrance and depth.
Make It Spicy: If you like a little heat, add a pinch of red pepper flakes or some chopped jalapeños when you add the garlic.
Cheese Variations: While Gruyère is the classic choice, you can experiment with other cheeses like provolone or even fontina for a slightly different melt and flavor.

French Onion Soup Beef is the kind of recipe that rewards patience and good technique, but it’s also one that’s forgiving and allows for personalization. Whether you’re feeding a crowd or enjoying a quiet night in, this soup brings comfort in every spoonful. The combination of caramelized onions, tender beef, and melty cheese creates a dish that’s not just a meal-it’s an experience.
