Ingredients

For this recipe, gather the following 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)

How to Make French Onion Soup

Step 1: Slice Onions

Slice the onions into ¼-inch thick slices.

Step 2: Sauté Onions

Heat the butter and olive oil in a large Dutch oven over medium heat.
* Add the sliced onions to the pot once the butter has melted.
* Cook while stirring every few minutes until very soft, browned but not burnt, and caramelized, about 25–30 minutes. Stir more frequently toward the end of cooking.

Step 3: Add Garlic and Flour

Add the minced garlic and flour to the pot.
* Cook while stirring for about 1 minute until fragrant.

Step 4: Deglaze with Grape Juice

Pour in the dry white grape juice.
* Cook for another minute or two while stirring, scraping up any browned bits from the bottom of the pot.

Step 5: Add Broth and Seasonings

Add the beef broth or stock along with salt, pepper, thyme sprigs (or dried thyme), and bay leaves.
* Increase heat to bring to a simmer; then reduce heat to maintain a low simmer.

Step 6: Simmer Soup

Cook uncovered at a low simmer for about 30 minutes, stirring occasionally.

Step 7: Toast Baguette Slices

While the soup simmers, preheat your oven to 400° F.
* Place baguette slices on a baking sheet and toast in the preheated oven for about 5–6 minutes until golden brown around the edges.

Step 8: Final Seasoning Check

Taste your soup and adjust salt and pepper if needed.
* Remove thyme stems and bay leaves before serving.

Step 9: Broil Cheese Topped Bowls

Preheat your oven broiler to 425° F.
* Place four oven-safe soup bowls on a heavy rimmed baking sheet.
* Transfer soup into each bowl.
* Top each bowl with two toasted baguette slices (browned side down) followed by shredded Gruyere cheese.

Step 10: Broil Until Golden Brown

Put the baking sheet with soup bowls under the broiler.
* Broil for about 2–4 minutes until cheese melts and lightly browns—watch closely to prevent burning.

Step 11: Serve Hot

Serve immediately, garnished with additional fresh thyme if desired. Be cautious as soup bowls will be very hot after broiling!

How to Serve French Onion Soup

French Onion Soup is a delightful meal that warms the soul. It’s perfect for sharing with family and friends, and there are several ways to elevate your serving experience.

Classic Presentation

• Serve in oven-safe bowls: Use individual bowls that can withstand the heat of the oven for an authentic experience.
• Garnish with fresh herbs: A sprinkle of fresh thyme adds color and enhances the flavor.

Pairing with Salads

• Mixed greens salad: A light, crisp salad complements the rich flavors of the soup.
• Caesar salad: The creamy dressing and crunchy croutons create a nice contrast to the smooth soup.

Accompanying Bread

• Crusty baguette slices: Serve extra toasted bread on the side for dipping or enjoying alongside.
• Garlic bread: This adds a flavorful twist and goes well with the soup’s savory notes.

With Cheese Platter

• Assorted cheeses: Offer a variety of cheeses that pair well, like brie or aged cheddar, to enhance the meal.
• Grapes or figs: Fresh fruit balances the richness of the soup and cheese.

How to Perfect French Onion Soup

Perfecting your French Onion Soup can elevate it from good to unforgettable. Here are some tips to help you achieve that depth of flavor.

• Choose quality onions: Yellow onions are ideal for caramelization. Their natural sweetness enhances the overall taste.
• Take your time caramelizing: Slow cooking onions allows them to develop a deep, rich color and flavor without burning.
• Use homemade broth: If possible, make your own beef broth for a richer taste compared to store-bought versions.
• Don’t skip the cheese: Gruyere offers a deliciously nutty flavor when melted on top. Ensure it’s shredded for even melting.
• Broil carefully: Keep an eye on the cheese while broiling; it can burn quickly if left unattended.
• Let it rest: Allowing the soup to sit for a few minutes before serving lets flavors meld together beautifully.

Best Side Dishes for French Onion Soup

French Onion Soup is hearty enough on its own but pairs wonderfully with various side dishes. Here are some suggestions to round out your meal.

1. Garlic Roasted Vegetables: A mix of seasonal veggies roasted with garlic complements the soup’s rich flavors.
2. Quinoa Salad: Nutritious and light, this salad adds texture and freshness to your meal.
3. Stuffed Mushrooms: Savory mushrooms filled with cheese and herbs offer great bite-sized enjoyment alongside your soup.
4. Caprese Skewers: Fresh mozzarella, tomatoes, and basil drizzled with balsamic glaze bring brightness to your plate.
5. Potato Wedges: Crispy wedges seasoned with herbs provide a satisfying crunch that pairs well with soup.
6. Cheesy Polenta: Creamy polenta topped with cheese makes for a comforting side dish that matches beautifully with French Onion Soup.

Common Mistakes to Avoid

Making French Onion Soup is a delightful experience, but common pitfalls can hinder your results. Here are some mistakes to watch out for:

• Skipping caramelization: Failing to properly caramelize the onions will lead to a flat-tasting soup. Cook them low and slow until they are golden brown for maximum flavor.
• Using low-quality broth: The broth is key in French Onion Soup. Always opt for a good quality beef broth or stock to ensure a rich taste.
• Overcooking or undercooking the bread: Toasting the baguette slices too long can make them too hard, while not enough time can leave them soggy. Aim for golden edges that still maintain some softness.
• Neglecting seasoning adjustments: Tasting your soup before serving is crucial. Adjust salt and pepper as needed to enhance the flavors.
• Forgetting about garnishes: Skipping fresh thyme or other garnishes can make your soup less visually appealing and flavorful. A little sprinkle makes a big difference.

Refrigerator Storage

• Store in an airtight container.
• Keep for 3-4 days in the refrigerator.

Freezing French Onion Soup

• Use freezer-safe containers or bags.
• Can be frozen for up to 3 months.

Reheating French Onion Soup

• Oven: Preheat to 350°F and heat soup in an oven-safe bowl until warm, about 15-20 minutes.
• Microwave: Place in a microwave-safe bowl, cover loosely, and heat in 1-minute intervals until hot.
• Stovetop: Pour into a pot and heat over medium until it reaches the desired temperature, stirring occasionally.
