Alton’s French Onion Soup Attacked by Sandi

My earliest memory of French Onion Soup involves a snow globe, a dimly lit restaurant, and the intoxicating aroma of caramelized onions hanging thick in the air. It was my sixth birthday, and my parents, in a rare splurge, took me to a “fancy” bistro. The bubbling, cheese-laden bowls arrived, each a miniature culinary volcano. I remember being utterly mesmerized, not just by the taste – that rich, savory sweetness – but by the sheer spectacle of it all. The anticipation of breaking through that golden crust, the steam rising to greet my face, it was pure magic. It sparked a lifelong love affair with this humble, yet deeply satisfying soup.

Recipe Overview

• Prep Time: 20 minutes
• Cook Time: 1 hour 30 minutes
• Total Time: 1 hour 50 minutes
• Servings: 4-6
• Yield: 4-6 bowls
• Dietary Type: Not Gluten-Free

Ingredients

• 4 sweet onions (like Vidalias, about 3 pounds)
• 3 tablespoons butter
• 1 teaspoon salt
• 2 cups white wine
• 3 cups beef broth
• 3 cups chicken broth
• Bouquet garni (thyme sprigs, bay leaf and parsley tied together with kitchen string)
• ½ teaspoon garlic powder
• 4-6 slices crusty French bread, 1 slice per serving
• Kosher salt
• Ground black pepper
• ½ cup Emmenthaler cheese, grated coarsely
• ½ cup Gruyere cheese, grated coarsely

Equipment Needed

• Electric skillet or large stock pot
• Kitchen string
• Baking sheet
• Oven-safe soup crocks
• Broiler

Instructions

1. Begin by preparing the onions. Trim the ends off each onion, then halve them lengthwise. Remove the peel and finely slice into half-moon shapes. This process can be a bit tear-inducing, so consider using a sharp knife or chilling the onions beforehand to minimize the tears.

2. Set an electric skillet to 300 degrees F (or a large stock pot to medium-high heat). Add the butter. Once the butter has melted, add a layer of onions to the skillet. Sprinkle with a little salt. Repeat layering onions and salt until all onions are in the skillet. It is important not to stir the onions until they have sweated down for about 15 minutes. This allows them to soften and release their natural sugars, which is key to the soup’s flavor.

3. After the initial 15 minutes, stir the onions occasionally until they are a dark mahogany color and have reduced to approximately 2 cups. This step is crucial and takes roughly 30 minutes. The key here is patience. The onions should be deeply caramelized, almost bordering on burnt, but not quite. This caramelization process develops the complex, sweet, and savory flavors that are characteristic of French Onion Soup. Avoid the temptation to stir too frequently.

4. Add enough white wine to cover the onions and turn the heat to high. Reduce the wine to a syrup consistency. This step deglazes the skillet, lifting up any flavorful browned bits from the bottom and incorporating them into the sauce. The wine also adds a layer of acidity that balances the sweetness of the onions.

5. Add the chicken and beef broths, garlic powder, and bouquet garni. Reduce the heat to low and simmer for 15 to 20 minutes. The bouquet garni infuses the soup with herbal notes, adding depth and complexity.

6. Place an oven rack in the top 1/3 of the oven and heat the broiler.

7. Cut the crusty French bread into rounds large enough to fit the mouth of the oven-safe soup crocks. Put a thin layer of butter on each slice. Place the slices on a baking sheet and place under the broiler for 1 minute. Turn over and toast the unbuttered side for an additional minute, or until browned. This creates a crispy, golden-brown crouton that will hold up well in the soup.

8. Season the soup mixture with salt and pepper to taste. Remove the bouquet garni. Ladle the soup into the oven-safe crocks, leaving about one inch to the lip. Place a bread round on top of each soup crock and top with a blend of grated Emmenthaler and Gruyere cheeses.

9. Broil until the cheese is bubbly and golden, 1 to 4 minutes depending on your preference. Keep a close eye on the crocks as they broil, as the cheese can burn quickly. For a truly decadent experience, broil until the cheese is deeply browned and slightly crispy.

Expert Tips & Tricks

• Caramelization is Key: Don’t rush the caramelization of the onions. This is where the magic happens. Low and slow is the way to go.
• Deglazing: Make sure to scrape up all those browned bits from the bottom of the pan when you add the wine. That’s where a lot of the flavor lies.
• Cheese Blend: The combination of Emmenthaler and Gruyere provides a lovely balance of nutty and slightly sharp flavors. Feel free to experiment with other cheeses like Fontina or Provolone.
• Bouquet Garni: If you don’t have fresh herbs, you can use dried herbs in a cheesecloth bag.
• Make Ahead: The soup base can be made a day or two ahead of time. Store it in the refrigerator until ready to use.

Serving & Storage Suggestions

Serve the French Onion Soup immediately after broiling, while the cheese is still bubbly and the bread is crispy. Garnish with a sprinkle of fresh parsley, if desired.

Leftover soup can be stored in an airtight container in the refrigerator for up to 3 days. To reheat, gently warm the soup on the stovetop or in the microwave. Note that the bread and cheese will soften upon reheating. To maintain the crispy texture, you can toast the bread separately and broil the cheese just before serving. Freezing is not recommended, as the texture of the onions and cheese may change upon thawing.

Variations & Substitutions

• Gluten-Free: Use gluten-free bread for the croutons.
• Vegetarian: Substitute vegetable broth for the beef and chicken broths.
• Spicy: Add a pinch of red pepper flakes to the soup for a little heat.
• Wine Substitution: If you prefer not to use wine, you can substitute an equal amount of beef broth or apple cider vinegar (use sparingly). However, the wine contributes significantly to the flavor profile.

FAQs (Frequently Asked Questions)

Q: Can I use yellow onions instead of sweet onions?
A: While sweet onions are preferred for their milder flavor and higher sugar content, yellow onions can be used in a pinch. Just be sure to caramelize them thoroughly to bring out their sweetness.

Q: Can I make this soup in a slow cooker?
A: Yes, you can. Caramelize the onions in a skillet as directed, then transfer them to the slow cooker with the remaining ingredients. Cook on low for 6-8 hours, or on high for 3-4 hours.

Q: What kind of bread is best for French Onion Soup?
A: A crusty French baguette or sourdough bread works well. The bread should be sturdy enough to hold up in the soup without disintegrating.

Q: Can I use pre-shredded cheese?
A: While pre-shredded cheese is convenient, it often contains cellulose, which can prevent it from melting as smoothly. Grating your own cheese is recommended for the best results.

Q: How do I prevent the cheese from burning under the broiler?
A: Keep a close eye on the crocks as they broil and adjust the distance from the broiler as needed. You can also tent the crocks with foil if the cheese starts to brown too quickly.

Final Thoughts

Now, go forth and conquer those onions! French Onion Soup may seem intimidating, but it’s a surprisingly simple dish to master.
