Ingredients You’ll Need
Gathering a handful of simple ingredients is all it takes to create this classic dish that bursts with deep, rich flavors. Each component plays a crucial role—onions add sweetness, the beef brings heartiness, and the Gruyere-crusted bread finishes it off with a satisfying cheesy crunch.
- 2 pounds yellow onions: Thinly sliced to slowly caramelize and develop a rich, sweet base for the soup.
- 1 head garlic: Whole cloves add a mellow, fragrant layer of flavor when roasted with the onions.
- 6 tablespoons olive oil: Divided use for roasting and searing to ensure perfectly cooked ingredients with plenty of flavor.
- 1 teaspoon sea salt: Enhances the natural sweetness of the onions and rounds out the flavors.
- 2 pounds beef chuck roast: Cut into ½ inch pieces for tender, juicy beef that melds beautifully into the soup.
- 2 tablespoons French onion seasoning: A homemade blend that lifts the soup’s onion-forward profile with aromatic spices.
- ¼ cup all-purpose flour: Helps thicken the broth, giving the soup a lovely, velvety texture.
- 8 cups beef stock: The savory backbone of the soup, providing depth and richness.
- 2 tablespoons Worcestershire sauce: Adds umami punch and a subtle tanginess to complement the beef.
- 1 pound baby potatoes (or cubed red potatoes): Bring a soft, comforting starchiness that holds up well in slow cooking.
- 2 sprigs fresh thyme (or fresh rosemary): Fresh herbs infuse the broth with fragrant, earthy notes.
- 2 bay leaves: Add subtle complexity and warmth as the soup simmers.
- 1 cup shredded Gruyere cheese (or Swiss cheese): The melty, nutty crown that makes this soup unforgettable.
- ½ loaf French bread: Sliced and toasted to create the perfect base for that cheesy topping.
How to Make French Onion Beef Soup with Gruyere-Crusted Bread Recipe
Step 1: Slow Roast the Onions and Garlic
Start by preheating your oven to 400°F. Thinly slice those beautiful yellow onions, and then add them along with the garlic cloves to your trusty cast iron Dutch oven. Drizzle with 4 tablespoons of olive oil and sprinkle with sea salt. Toss everything so each slice is well-coated. Cover the pot and pop it into the oven to slowly roast for one hour. This step is essential because it develops that signature deep caramelized sweetness in the onions, laying down the flavorful foundation of the soup.
Step 2: Sear the Beef Chuck
After roasting the onions, reduce your oven temperature to 350°F. Transfer the onions and garlic to a plate to allow any excess liquid to drain. Place your Dutch oven on the stovetop over high heat. While that heats up, toss your cubed beef chuck in the French onion seasoning, ensuring every piece is perfectly seasoned. Heat the remaining 2 tablespoons olive oil in the pot, then sear the beef for 4-6 minutes until all sides develop a beautiful brown crust. This Maillard reaction is where your beef gains incredible flavor. Remove the beef with a slotted spoon and set aside.
Step 3: Deglaze and Thicken the Soup
Pour a splash (about ¼ cup) of beef stock into the hot pot to deglaze it, scraping up all those yummy browned bits stuck to the bottom. These bits are packed with flavor and critical for a rich broth. Next, sprinkle the flour evenly over the pot’s contents and stir continuously for one minute to cook out the raw taste. This will give your soup a wonderfully unctuous texture once you add the rest of the liquids.
Step 4: Build and Cook the Soup
Pour in the remaining beef stock along with the Worcestershire sauce, stirring to marry all the layers of flavor together. Bring the mixture to a rolling boil over high heat. Then, return the beef, roasted onions, and garlic to the pot. Add the baby potatoes, fresh thyme sprigs, and bay leaves. Cover tightly with a lid or foil, and transfer the Dutch oven to your preheated oven for two hours. This slow, gentle cooking tenderizes the beef and lets the flavors develop into a soulful, hearty soup.
Step 5: Prepare the Gruyere-Crusted Bread
When your soup is done, remove it from the oven and toss out the thyme and bay leaves. Set the oven to broil on high and position the rack in the middle. Slice the French bread and lightly toast the slices on a baking sheet, brushing them with melted butter or a quick spritz of cooking spray. Broil for 1-2 minutes until golden and crisp. Ladle the soup into oven-safe bowls, top each with a toasted slice, and generously sprinkle shredded Gruyere cheese on top. Return the bowls to the oven under the broiler for another 1-2 minutes until the cheese is bubbly and golden. This finishing touch delivers an irresistible cheesy crust that defines the French Onion Beef Soup with Gruyere-Crusted Bread Recipe experience.
How to Serve French Onion Beef Soup with Gruyere-Crusted Bread Recipe
Garnishes
For garnish, consider fresh thyme leaves or finely chopped parsley to add a hint of green that brightens the presentation. A sprinkle of cracked black pepper or a few flakes of smoked paprika can also deepen the aroma and visual appeal.
Side Dishes
This soup shines as a standalone meal but pairs beautifully with a crisp green salad tossed with a tangy vinaigrette or roasted seasonal vegetables. A glass of robust red wine will also complement the rich beef and caramelized onion flavors perfectly.
Creative Ways to Present
Want to wow your guests? Serve the soup in mini cast iron cocottes or rustic bread bowls for a charming presentation. Alternatively, try layering the soup and cheesy toast in clear glasses for an elegant, modern twist on a classic comforting dish.
Make Ahead and Storage
Storing Leftovers
After enjoying your soup, any leftovers should be cooled to room temperature and stored in airtight containers in the refrigerator. The flavors even deepen overnight, so leftovers are just as delicious, if not more so, the next day.
Freezing
This soup freezes wonderfully. Transfer cooled soup without the bread and cheese topping into freezer-safe containers. It will keep its flavor and texture well for up to 3 months. Be sure to freeze in portions for easy thawing.
Reheating
Reheat frozen or refrigerated soup gently on the stovetop over low to medium heat, stirring occasionally. Avoid microwaving directly with the bread and cheese to preserve texture. Toast fresh bread and melt fresh cheese on top after warming the soup.
FAQs
Can I use a different type of cheese?
Absolutely! While Gruyere is traditional for its nutty flavor and excellent melting quality, Swiss cheese or even a mild mozzarella can work. Just choose a cheese that melts well and has good flavor.
Is beef chuck the best cut for this soup?
Beef chuck is ideal due to its marbling and tenderness after slow cooking, which creates a rich, succulent texture perfect for this soup. Other cuts like brisket can work but may require different cooking times.
Can I make the French onion seasoning from scratch?
Yes, making your own French onion seasoning adds a wonderful homemade touch! It usually includes dried onion flakes, garlic powder, parsley, and other herbs. Feel free to customize based on your taste preferences.
What can I substitute for baby potatoes?
Red potatoes, Yukon Gold, or fingerlings all make great substitutes as they hold their shape well and absorb flavors beautifully during the slow-cooking process.
Is it necessary to broil the bread with cheese on top?
Broiling is the best way to achieve that signature golden, bubbly crust, but if you don’t have a broiler, you can bake the soup at a high oven temperature until the cheese melts and bubbles. Just keep an eye on it to prevent burning.

Toppings
- 1 cup shredded Gruyere cheese or Swiss cheese
- ½ loaf French bread, sliced
- Cooking spray or melted butter (for toasting bread)
Instructions
- Preheat Oven and Prepare Onions: Preheat the oven to 400°F. Thinly slice the onions using a sharp knife or mandoline for even cooking.
- Cook Onions and Garlic: Place the sliced onions and whole garlic cloves into an oven-safe cast iron Dutch oven. Drizzle with 4 tablespoons olive oil and sprinkle with sea salt. Toss to coat evenly. Cover the pot and bake for 1 hour until the onions are softened and caramelized.
- Reduce Oven Temperature: After baking, remove the Dutch oven from the oven and lower the oven temperature to 350°F.
- Remove Onions and Garlic: Transfer the cooked onions and garlic from the Dutch oven to a rimmed plate or cutting board with grooves to catch any liquid.
- Heat Dutch Oven on Stove: Place the Dutch oven on the stove over high heat to prepare for searing the beef.
- Season the Beef: Toss the cubed beef chuck with French onion seasoning to evenly coat the meat with flavorful spices.
- Sear the Beef: Add 2 tablespoons olive oil to the hot Dutch oven. Once shimmering, add the beef pieces and sear for 4 to 6 minutes, turning occasionally until all sides are browned. Remove beef with a slotted spoon and set aside with the onions and garlic.
- Deglaze the Pot: Pour ¼ cup beef stock into the pot and stir, scraping the bottom to loosen any browned bits. These add flavor to the soup.
- Add Flour: Sprinkle the all-purpose flour evenly over the contents in the pot and stir to combine. Cook for 1 minute to remove the raw flour taste and thicken the soup later.
- Add Remaining Liquids: Pour in the remaining 7¾ cups beef stock and Worcestershire sauce. Stir well and increase the heat to high to bring the stock to a boil.
- Combine Ingredients: Return the seared beef, onions, and garlic to the Dutch oven. Add the potatoes, fresh thyme sprigs, and bay leaves for aromatic flavor.
- Bake the Soup: Cover the Dutch oven with its lid or tightly with aluminum foil. Place it in the oven preheated to 350°F and bake for 2 hours to allow flavors to develop and beef to become tender.
- Finish Soup: Remove the pot from the oven. Use tongs to discard the bay leaves and thyme sprigs from the soup.
- Prepare Bread Topping (Optional): Preheat the oven broiler to high and set a rack in the middle position. Arrange the sliced French bread on a baking sheet and brush with melted butter or spray with cooking spray. Broil for 1-2 minutes until lightly toasted; watch carefully to prevent burning. Remove from oven.
- Assemble and Broil Bowls: Ladle the hot soup into oven-safe bowls. Top each with a slice of toasted bread and a generous handful of shredded Gruyere cheese. Place the bowls on a baking sheet and broil in the oven for 1-2 minutes until the cheese melts and becomes bubbly and golden.
Notes
- Using a cast iron Dutch oven allows for both stovetop searing and oven baking, enhancing the flavor development.
- French onion seasoning is typically a blend of granulated onion, garlic powder, herbs, and spices; it can be homemade or store-bought.
- Baby potatoes can be substituted with cubed red potatoes for similar texture.
- Gruyere cheese provides the classic nutty taste for the toast topping but Swiss cheese can be used as a milder alternative.
- Monitor the broiler carefully when toasting bread and melting cheese to avoid burning.
- Leftover soup can be cooled and refrigerated for up to 3 days or frozen for up to 3 months.
