Detailed Directions and Instructions

Step 1: Prepare the Onions

Slice the onions thinly, aiming for uniform pieces to ensure even cooking. Use a sharp knife for better control.

Step 2: Cook the Onions

In a large pot, melt the butter over medium heat. Add sliced onions, stirring to coat them in butter. Cook slowly, stirring frequently, until onions are deeply caramelized and browned, about 30-40 minutes.

Step 3: Add Garlic

Once the onions are caramelized, add minced garlic to the pot. Cook for an additional minute until fragrant.

Step 4: Deglaze the Pot

Pour in the white wine, scraping up any browned bits from the bottom of the pot. Allow the wine to reduce by half, which should take about 5 minutes.

Step 5: Add Broth and Seasonings

Stir in both beef broth and thyme. Bring the mixture to a simmer, then reduce the heat and let it simmer for about 20 minutes. Adjust seasoning with salt and pepper to taste.

Step 6: Prepare the Bread and Cheese

While the soup is simmering, preheat your oven to 350°F (175°C). Slice the baguette into thick slices and place them on a baking sheet. Toast in the oven for about 10 minutes until golden brown. Remove and top each slice with grated cheese.

Step 7: Assemble the Soup

Ladle the hot soup into oven-safe bowls. Place the toasted bread on top of each bowl of soup, ensuring the cheese is on top of the bread.

Step 8: Broil the Soup

Place the bowls under the broiler for 2-5 minutes, or until the cheese is melted and bubbly. Watch closely to prevent burning.

Step 9: Serve and Enjoy

Remove the bowls from the oven carefully. Allow to cool slightly before serving, and enjoy your homemade French onion soup!

Cook techniques

Sautéing Onions

Sautéing the onions slowly helps to develop their sweetness and flavor. Use medium to medium-low heat to allow the onions to caramelize without burning.

Deglazing with Wine

Deglazing the pot with white wine after sautéing enhances the flavor of the soup by lifting the browned bits off the bottom and incorporating them into the broth.

Simmering

Allowing the soup to simmer allows the flavors to meld together. A slow simmer will extract flavors from the broth and enhance the richness of the soup.

Broiling Cheese

Broiling the cheese on top just before serving creates a delicious, bubbly crust that adds texture and flavor to the French onion soup.
