Ingredients
(Tip: You’ll find the full list of ingredients and measurements in the recipe card below.)
For the soup base: yellow onions, thinly sliced butter olive oil garlic, minced all-purpose flour beef or vegetable broth heavy cream milk thyme bay leaf salt black pepper
For topping: Gruyere or Swiss cheese, shredded crusty bread slices
Directions
In a large pot, melt the butter with olive oil over medium heat. Add the sliced onions and cook slowly, stirring often, until deeply caramelized and golden brown, about 25–30 minutes.
Add the garlic and cook for another minute until fragrant.
Sprinkle in the flour and stir well to coat the onions, cooking for 1–2 minutes.
Gradually pour in the broth while stirring to prevent lumps. Add thyme and bay leaf, then bring to a simmer.
Stir in the milk and heavy cream, allowing the soup to gently simmer until slightly thickened.
Season with salt and pepper to taste. Remove the bay leaf before serving.
Ladle the soup into oven-safe bowls, top with toasted bread slices and shredded cheese.
Place under the broiler for a few minutes until the cheese is melted and bubbly.
Add cooked bacon for a smoky flavor. Use chicken broth instead of beef broth for a lighter taste. Include diced potatoes for a more traditional chowder feel. Add a splash of white wine while cooking the onions for extra depth. Use different cheeses like cheddar or mozzarella for variety.
Storage/Reheating
Store the soup (without bread and cheese topping) in an airtight container in the refrigerator for up to 4 days. Reheat gently on the stovetop over medium heat, stirring occasionally. Add a splash of milk or broth if it thickens too much. Prepare fresh toppings when ready to serve. This soup can be frozen without toppings for up to 2 months.
