Ingredients
Scale
Main Ingredients:
- 4 large onions, thinly sliced
- 1 pound mushrooms (button or cremini), sliced
- 4 cups beef or vegetable broth
- 1 cup heavy cream
- 1 cup shredded Gruyère or Swiss cheese
- 1 baguette, sliced and toasted
Cooking Fats and Seasonings:
- 2 tablespoons unsalted butter
- 1 tablespoon olive oil
- 3 cloves garlic, minced
- 1 tablespoon fresh thyme leaves
- 1/2 cup dry white wine
Finishing Ingredients:
- Salt to taste
- Black pepper to taste
Instructions
- Melt butter and olive oil in a large pot over medium heat, creating a flavorful base for caramelizing onions.
- Slowly transform sliced onions to a rich, golden-brown color, stirring periodically for 25-30 minutes to develop deep, sweet flavor.
- Introduce minced garlic, sliced mushrooms, and fresh thyme to the caramelized onions, sautéing until mushrooms release moisture and develop golden edges.
- Deglaze the pot with white wine, scraping up concentrated flavor bits from the bottom, and allow liquid to reduce for 3-4 minutes.
- Pour in broth and simmer covered for 15 minutes, allowing ingredients to meld and intensify their aromatic qualities.
- Incorporate heavy cream, seasoning with salt and pepper, and gently cook for an additional 5 minutes to create a luxurious, velvety texture.
- Transfer soup into oven-safe bowls, layering toasted baguette slices across the surface.
- Generously sprinkle Gruyère cheese over the bread, creating a complete coverage.
- Position bowls under broiler at 500°F for 2-3 minutes until cheese melts, bubbles, and transforms into a golden-brown crust.
- Serve immediately while cheese remains hot and crispy, presenting a comforting, restaurant-quality soup.
Notes
- Let caramelized onions reach a deep golden-brown color for maximum sweetness and rich flavor development.
- Use a mix of mushroom varieties like cremini and shiitake to create more complex, layered umami taste profiles.
- Consider replacing heavy cream with coconut milk for a dairy-free version that maintains creamy texture and adds subtle nutty undertones.
- Swap out traditional Gruyère with nutritional yeast or vegan cheese alternatives to accommodate plant-based dietary preferences without compromising the soup’s luxurious character.
