Ingredients

This French Onion Soup is the best cozy, comforting meal to enjoy on a chilly day. This full-flavored soup gets its rich flavor from caramelized onions, a good quality beef broth or stock, and toasted cheesy baguette slices.

Ingredients:
– 3 pounds yellow onions (3-4 large onions)
– 3 tablespoons unsalted butter
– 1 tablespoon extra virgin olive oil
– 2 cloves garlic (minced)
– 2 tablespoons all-purpose flour
– ½ cup dry white grape juice
– 6 cups low sodium beef broth or stock
– ½ teaspoon salt (or to taste)
– ¼ teaspoon black pepper (or to taste)
– 4 sprigs fresh thyme (or 1 teaspoon dried thyme)
– 2 bay leaves
– 8 slices baguette
– 2 ounces Gruyere cheese (shredded)

How to Make French Onion Soup

Step 1: Slice the Onions

Slice the yellow onions into ¼-inch thick slices. This will ensure they cook evenly and caramelize beautifully.

Step 2: Heat the Butter and Oil

Heat the unsalted butter and extra virgin olive oil in a large Dutch oven or heavy pot over medium heat.

Step 3: Caramelize the Onions

Once the butter has melted:
1. Add the sliced onions to the pot.
2. Cook while stirring every few minutes until they are very soft, browned (but not burnt), and caramelized; this should take about 25–30 minutes.
3. Near the end of cooking, stir more frequently to prevent burning.

Step 4: Add Garlic and Flour

Add the minced garlic and all-purpose flour to the pot:
1. Cook while stirring for about one minute until well combined.

Step 5: Deglaze with Grape Juice

Pour in the dry white grape juice:
1. Cook for an additional 1–2 minutes while stirring and scraping up any browned bits from the bottom of the pot.

Step 6: Incorporate Broth and Seasonings

Add in:
– The low sodium beef broth or stock
– Salt, black pepper, thyme sprigs, and bay leaves

Increase heat to bring everything to a simmer then reduce heat back down to low.

Step 7: Simmer the Soup

Let your soup simmer uncovered for about:
1. 30 minutes, stirring occasionally.

Step 8: Toast Baguette Slices

While your soup simmers:
1. Preheat your oven to 400° F.
2. Place your baguette slices on a baking sheet.
3. Toast them in the preheated oven for approximately 5–6 minutes, until they’re golden brown around the edges.

Step 9: Final Seasoning Adjustments

Taste your soup:
1. Adjust salt and pepper if necessary.
2. Remove thyme stems and bay leaves before serving.

Step 10: Broil Cheese Topping

Preheat your oven broiler to 425° F:
1. Place four oven-safe soup serving bowls on a heavy rimmed baking sheet.
2. Transfer the soup into these bowls.
3. Top each bowl with two toasted baguette slices (browned side down) followed by sprinkling shredded Gruyere cheese over them.

Step 11: Broil Until Golden

Place your baking sheet with soup bowls into your oven:
1. Broil for about 2–4 minutes, until cheese melts and lightly browns—watch closely to avoid burning!

Step 12: Serve

Serve immediately garnished with additional fresh thyme if desired:
Be careful as these bowls will be very hot after being in the oven! Enjoy your warm bowl of French Onion Soup!

Classic Presentation

How to Perfect French Onion Soup

To ensure your French Onion Soup reaches its full potential, follow these handy tips for perfection in every bowl.

• Use Quality Onions: Yellow onions are ideal for caramelizing due to their natural sweetness. Choose fresh, firm onions for the best flavor.
• Take Time for Caramelization: Don’t rush the onion cooking process; slow and steady caramelization develops deep flavors and rich color.
• Use Low Sodium Broth: This allows you to control the saltiness better while letting the flavors shine through without being overpowering.
• Toast Bread Properly: Ensure your baguette slices are toasted until golden brown. This will help them hold up against the broth without becoming soggy too quickly.
• Experiment with Cheese: While Gruyere is traditional, feel free to mix in other cheeses like Swiss or mozzarella for different flavor profiles.
• Adjust Seasonings Last: Taste before serving and adjust salt and pepper as needed; this ensures your soup has just the right balance.

Best Side Dishes for French Onion Soup

1. Mixed Green Salad: A light salad with vinaigrette provides brightness against the rich soup.
2. Garlic Bread: A crispy garlic bread can complement the cheesy baguette topping perfectly.
3. Roasted Vegetables: Seasonal roasted veggies add color and nutrients that pair nicely.
4. Stuffed Mushrooms: Savory stuffed mushrooms offer an elegant touch that matches well with the soup.
5. Bruschetta: Tomato bruschetta topped with basil can add freshness and zing alongside your soup.
6. Cheese Quesadillas: These cheesy bites are easy to prepare and make great dippers for your soup.

Common Mistakes to Avoid

Making French Onion Soup can be a delightful experience, but several common mistakes can hinder your results.

• Boldly Choosing the Wrong Onions: Using sweet or red onions instead of yellow onions can lead to a soup that lacks depth. Stick with yellow onions for the best flavor.
• Boldly Skipping the Caramelization: Rushing the caramelization process will result in underdeveloped flavors. Take your time to cook the onions slowly until they are deeply browned.
• Boldly Ignoring Broth Quality: Using low-quality broth can make your soup taste bland. Opt for high-quality beef broth or stock to enhance the overall flavor.
• Boldly Forgetting Seasoning Adjustments: Not tasting and adjusting seasonings can lead to an unbalanced soup. Always taste as you go and add salt or pepper to suit your palate.
• Boldly Overcrowding the Pot: Adding too many onions at once can prevent proper caramelization. Work in batches if necessary to ensure even cooking.

Storage and Reheating

Refrigerator Storage

• Store in an airtight container for up to 3-4 days.
• Allow the soup to cool completely before sealing it in the container.

Freezing French Onion Soup

• Freeze in freezer-safe containers for up to 3 months.
• Leave some space at the top of the container for expansion during freezing.

Reheating French Onion Soup

• Oven: Preheat to 350°F (175°C), transfer soup to an oven-safe dish, cover with foil, and heat for about 20-25 minutes.
• Microwave: Place soup in a microwave-safe bowl, cover loosely, and heat on high for 2-3 minutes, stirring halfway through.
• Stovetop: Heat over medium-low heat in a pot, stirring occasionally until warmed through, about 10-15 minutes.
