Ingredients
Scale
Main Ingredients:
- 3 large Tennessee sweet onions
- 4 cups beef broth
- 1 baguette
- 4 ounces Gruyere cheese
- 2 ounces Parmesan cheese
Supporting Ingredients:
- 2 tablespoons olive oil
- 1 tablespoon butter
- ¼ cup dry red wine
- 1 clove garlic
Seasoning and Herbs:
- 1 teaspoon granulated sugar
- ½ teaspoon salt
- ¼ teaspoon black pepper
- 1 bay leaf
- 1 sprig fresh thyme
Instructions
- Slice 3 Tennessee sweet onions into thin ⅛-inch strips after chilling them for 30 minutes to minimize tears.
- Warm 2 tablespoons olive oil and 1 tablespoon butter in a large pot over medium heat until butter melts completely.
- Sprinkle 1 teaspoon sugar, ½ teaspoon salt, and ¼ teaspoon black pepper over onions, thoroughly coating each slice.
- Reduce heat to low and slowly cook onions, stirring every 10-15 minutes to prevent sticking and ensure even caramelization.
- Continue cooking for 45-60 minutes, watching carefully as onions transform from pale to deep golden brown and develop a jam-like consistency.
- Pour ¼ cup red wine into the pot, increasing heat to medium and scraping the bottom to release delicious browned bits.
- Add 4 cups beef broth, 1 bay leaf, and 1 thyme sprig to the pot, bringing the mixture to a gentle simmer.
- Cover and let the soup simmer on low heat for 30-45 minutes, allowing flavors to meld and intensify.
- Preheat your oven to 375°F and slice the baguette into 1-inch thick rounds.
- Rub each bread slice with the halved garlic clove to infuse subtle flavor.
- Sprinkle 4 ounces Gruyere and 2 ounces Parmesan cheese over bread slices.
- Bake bread for 8-10 minutes until cheese melts and bread turns golden brown.
- Switch oven to broiler setting and set to high heat.
- Ladle hot soup into oven-safe bowls, leaving one inch of space at the top.
- Float cheesy croutons on top of each soup bowl.
- Broil for 1-2 minutes until cheese bubbles and turns light brown, watching carefully to prevent burning.
- Serve the soup immediately while hot and cheesy.
Notes
- Chill onions before slicing to minimize tears and make cutting easier.
- Use a mix of butter and olive oil for deeper flavor and better caramelization.
- Patience is key when caramelizing onions – low and slow brings out the sweetest, richest flavor.
- For a vegetarian version, swap beef broth with vegetable stock and add a splash of soy sauce for depth.
