Can You Make French Onion Soup from Prosecco or Champagne?

Absolutely, you can make French onion soup with prosecco or champagne! Both can bring a unique twist to the classic recipe, adding a touch of sweetness and a light, aromatic flavor that pairs beautifully with caramelized onions. Here’s how to make a delightful French onion soup using either prosecco or champagne.

Ingredients:

• 6 large yellow onions, thinly sliced

• 4 tbsp unsalted butter

• 1 tbsp olive oil

• 2-3 cloves garlic, minced

• 1 tsp sugar

• 1 tsp salt

• 1/4 tsp black pepper

• 1/2 cup prosecco or champagne (either will work, but keep in mind that champagne may lend a slightly richer, drier flavor while prosecco is a bit sweeter)

• 6 cups beef or vegetable broth

• Fresh thyme or bay leaves

• Baguette slices

• 1 1/2 cups grated Gruyère or Swiss cheese

Caramelize the Onions: In a large pot, melt butter with olive oil over medium heat. Add the sliced onions, garlic, salt, and pepper. Cook, stirring frequently, until onions are soft and golden (about 30-40 minutes). Sprinkle in the sugar to help with caramelization.

Add the Wine: Pour in the prosecco or champagne, scraping up any browned bits on the bottom of the pot. Allow the liquid to reduce by half to concentrate its flavor.

Simmer the Soup: Add the broth and thyme or bay leaves. Bring to a simmer and cook for another 15-20 minutes to blend the flavors. Season with salt and pepper to taste.

Serve: Ladle soup into bowls, top with a toasted baguette slice, and sprinkle generously with grated Gruyère. Broil until the cheese is bubbly and golden, then serve!

Using prosecco or champagne brings a slight effervescence and nuanced sweetness that makes this soup extra special. Enjoy!
