| Yellow onions | 4 large | Thinly sliced |
| Unsalted butter | 4 tablespoons | Melted |

For the Topping
The classic topping adds that signature golden crust and richness that defines this soup:

Prep Work
Before diving into the cooking process, preparing our ingredients with precision sets the foundation for the Famous Barr French Onion Soup’s rich flavor and perfect texture.
Preparing the Onions
The key to our soup’s deep sweetness and complexity starts with properly prepping the onions.
- Choose 4 to 5 large yellow onions—these provide the ideal balance of sweetness and sharpness.
- Peel the onions carefully to avoid tearing, which can cause bitterness.
- Slice the onions uniformly into thin half-moons about 1/8 inch thick. Consistent slices cook evenly, leading to perfect caramelization.
- Tip: Use a sharp chef’s knife to ensure clean cuts. Dull knives bruise the onions, releasing unwanted bitterness.
Preparing the Broth
Our broth is the soul of the soup, delivering that unmistakable richness.
| Ingredient | Quantity | Preparation |
|---|---|---|
| Beef broth | 6 cups | Use low-sodium for controlled saltiness |
| Dry white wine | 1/2 cup | Optional for depth |
| Garlic cloves | 2 cloves | Minced or crushed |
| Fresh thyme sprigs | 2 sprigs | Whole sprigs for easy removal |
| Bay leaf | 1 leaf | For subtle herbal aroma |
- Measure the beef broth carefully to maintain the soup’s balanced intensity.
- Mince the garlic finely to release its fragrant aroma without overpowering the broth.
- If using white wine, measure exactly half a cup to add elegance and enhance the layered flavors.
- Gather fresh herbs for infusion; these contribute to the authentic French flavor profile.
- Keep all ingredients close at hand to streamline the cooking process once caramelized onions are ready.
Cooking Instructions
Follow these clear steps to create the Famous Barr French Onion Soup with its unforgettable rich flavor and perfect texture. Each stage builds the depth and warmth this classic dish is known for.
Caramelizing the Onions
- Prepare the onions: Use 4 to 5 large yellow onions, thinly sliced into uniform half-moons to ensure even cooking.
- Heat the pan: Place a large heavy-bottomed skillet over medium heat and add 4 tablespoons of unsalted butter.
- Add onions: Once the butter is melted and slightly bubbling, add the sliced onions. Stir to coat them evenly.
- Cook slowly: Let the onions cook slowly, stirring every 5 minutes for about 40 to 50 minutes. This process draws out their natural sugars, creating a deep golden brown color.
- Avoid rushing: If onions begin to stick or brown too quickly, reduce heat slightly; slow caramelization is key to developing their natural sweetness without burning.
Adding the Broth and Seasonings
- Transfer onions: Move the caramelized onions into a Dutch oven or heavy pot.
- Add garlic: Stir in 2 cloves of minced garlic and cook for 1 minute until fragrant.
- Pour broth and wine:
- Add 6 cups of low-sodium beef broth.
- Optionally add ½ cup of dry white wine for complexity.
- Add herbs and seasoning:
- Add 2 sprigs of fresh thyme and 1 bay leaf.
- Season with 1 teaspoon salt and ½ teaspoon freshly ground black pepper.
- Bring to a simmer: Stir gently and raise the heat until the soup just begins to simmer.
| Ingredient | Quantity | Purpose |
|---|---|---|
| Yellow onions | 4 to 5 large | Base flavor, caramelization |
| Unsalted butter | 4 tablespoons | Caramelizing agent |
| Minced garlic | 2 cloves | Aromatic flavor |
| Low-sodium beef broth | 6 cups | Rich umami soup base |
| Dry white wine | ½ cup (optional) | Adds depth and acidity |
| Fresh thyme | 2 sprigs | Herbal fragrance |
| Bay leaf | 1 leaf | Earthy aroma |
| Salt | 1 teaspoon | Enhances all flavors |
| Ground black pepper | ½ teaspoon | Subtle heat |
Simmering the Soup
- Simmer gently: Reduce heat to low and let the soup simmer uncovered for at least 30 minutes. This allows flavors to meld and develop.
- Stir occasionally: Prevent sticking and ensure even cooking by stirring every 8 to 10 minutes.
- Adjust seasoning: Taste and adjust salt and pepper as needed before serving.
- Prepare to serve: Ladle the hot soup into oven-safe bowls topped with toasted French baguette slices and Gruyère cheese for broiling.
By carefully following these steps, we create the rich, melt-in-your-mouth flavor and texture that make Famous Barr French Onion Soup truly memorable.
Assembling the Soup
Now that our French onion soup base has simmered and developed its rich flavors, it is time for the final assembly. This step is crucial to creating the iconic layers of texture and flavor that define Famous Barr French Onion Soup.
Adding the Bread and Cheese Topping
- Prepare the toasted baguette slices
Arrange the French baguette slices on a baking sheet. Toast under a broiler or in a hot oven (400°F / 205°C) for 2–3 minutes per side until golden, crisp but still sturdy. The bread acts as the perfect base to hold the melted cheese without becoming soggy.
- Ladle soup into oven-safe bowls
Using a ladle, fill the oven-safe soup bowls with the hot, aromatic French onion soup. We recommend filling them about three-quarters full to leave room for the bread and cheese topping.
- Place toasted bread over the soup
One or two slices of the toasted baguette should be placed gently on top of the soup surface. This layer will soak just enough soup without losing its texture.
- Top with Gruyère cheese
Generously sprinkle grated Gruyère cheese over the bread to cover it completely. The cheese layer provides the signature golden crust and delightful melt that crowns the dish.
- Broil until bubbly and golden
Place the bowls on a baking sheet and broil in the oven for 3–5 minutes, watching closely. The cheese should become bubbly with a slightly browned crust. Avoid over-broiling to prevent burning.
| Step | Details | Timing/Temperature |
|---|---|---|
| Toast baguette slices | 2-3 minutes per side under broiler | 400°F / 205°C |
| Ladle soup into bowls | Fill about 3/4 full | Hot soup ready |
| Broil assembled bowls | Until cheese bubbles and browns | 3-5 minutes under broiler |
“The key to the perfect final layer lies in balancing the bread texture and cheese melt. Too soggy bread or burnt cheese can overpower the delicate caramelized onion flavor beneath.”
By carefully layering the toasted bread and melting the Gruyère, we achieve the authentic classic French onion soup experience—where rich broth, sweet onions, crunchy bread, and golden cheese unite in every satisfying spoonful.
Baking the Soup
To achieve the signature rich crust and satisfyingly gooey texture, baking and broiling our Famous Barr French Onion Soup is a crucial final step. This process melds the layers, elevating the flavors and textures into the perfect bowl of comfort.
Broiling for the Perfect Melted Cheese
We start by preheating our broiler to high heat. Using oven-safe soup bowls, we carefully ladle the simmered soup into each dish. Then we layer on the toasted French baguette slices, ensuring an even, full coverage that will soak up the broth without sinking too quickly.
Next we generously pile on the Gruyère cheese, the key to the iconic golden crust. The cheese should cover the bread entirely to create a melt that is both bubbly and creamy. For optimal results, we use about 1 to 1.5 ounces of grated Gruyère per bowl.
| Step | Details | Purpose |
|---|---|---|
| Preheat broiler | Set to high | Ensure intense heat for melting |
| Ladle soup | Fill oven-safe bowls ¾ full | Avoid overflow while baking |
| Add toasted baguette | One or two slices per bowl | Absorb broth and provide crunch |
| Layer Gruyère cheese | 1 – 1.5 oz grated cheese per bowl | Create golden, bubbly cheese crust |
| Broil | 3-5 minutes, watch carefully | Melt and brown cheese without burning |
We place the bowls on a baking sheet and slide them into the broiler rack. The intense heat quickly melts the Gruyère until it is bubbling and turns a rich golden-brown. We watch closely to prevent burning while achieving that coveted cheesy crust.
Once the cheese is perfectly melted and slightly caramelized in spots, we remove the soup from the oven. The result is the classic Famous Barr French Onion Soup experience: a deeply savory broth, sweet caramelized onions, crisp toasted bread, and a thick, golden cheese crust that pulls away in delicious strings as we dive in.
Let the soup rest for a minute to cool slightly before serving. This step allows the crust to set and ensures every spoonful delivers a harmonious blend of temperatures and textures.
Serving Suggestions
To elevate the experience of our Famous Barr French Onion Soup, consider these serving tips that highlight the dish’s rich flavors and textures.
- Pair with a Crisp Green Salad
A simple green salad dressed lightly with lemon vinaigrette complements the soup’s deep savory notes and creamy cheese topping. The refreshing crunch balances the softness of caramelized onions and melted Gruyère.
- Serve with Rustic Bread
Alongside the classic toasted baguette slices already incorporated in the recipe, offer additional rustic country bread or sourdough. These breads provide extra texture and are perfect for dipping into the flavorful broth.
- Accompany with a Glass of Dry White Wine or Light Red Wine
Wines such as a crisp Sauvignon Blanc or a light Pinot Noir enhance the soup’s complexity and mirror the subtle wine notes used in the broth base.
- Add Fresh Herbs for Garnish
Sprinkle finely chopped fresh thyme or parsley on top right before serving. This adds a burst of herbal aroma and a fresh contrast to the rich soup.
- Offer a Side of Roasted Vegetables
Roasted root vegetables such as carrots, parsnips, or beets with minimal seasoning provide a wholesome and vibrant side that complements the hearty soup.
Serving Temperature and Presentation Tips
| Step | Detail |
|---|---|
| Temperature | Serve the soup hot immediately after broiling to preserve the melted cheese’s gooey texture. Allow a brief 2–3 minute rest for easier handling. |
| Presentation | Use oven-safe bowls that showcase the rich golden crust. Present on a wooden board or wide plate to catch any drips. |
| Portion Size | Ladle about 1.5 cups (360 ml) per serving to offer a generous yet manageable portion. |
