How to Make Dutch Oven French Onion Soup

Ingredients You’ll Need

4 large onions, thinly sliced, 4 tablespoons unsalted butter, 1 tablespoon olive oil, 1 teaspoon sugar, 2 cloves garlic, minced, 8 cups beef broth, 1 cup dry cooking liquid (for example, extra beef broth or dry white grape juice mixed with water), 2 teaspoons fresh thyme leaves, Salt and pepper to taste, 8 slices of baguette, 2 cups grated Gruyère cheese

Step-by-Step Directions

In a Dutch oven, melt the butter and olive oil over medium heat.
Add the sliced onions and sugar, cooking until the onions are caramelized, about 30-40 minutes.
Stir in the minced garlic and cook for an additional minute.
Pour in the cooking liquid, scraping the bottom of the pot to deglaze.
Add the beef broth and thyme, then bring to a simmer.
Season with salt and pepper to taste.
Preheat the oven to 350°F (175°C).
Place the baguette slices on a baking sheet and toast in the oven until golden brown.
Serve the soup in bowls, topping each with a slice of toasted baguette and a generous amount of Gruyère cheese.
Broil the bowls in the oven until the cheese is bubbly and golden.

How to Serve Dutch Oven French Onion Soup

Serve hot in oven-safe bowls. Place a toasted baguette slice on each bowl, add grated cheese, and broil until the cheese bubbles and turns golden. Offer fresh thyme or a light sprinkle of black pepper on top. Pair the soup with a small green salad or roasted vegetables for a simple, balanced meal.

How to Store Dutch Oven French Onion Soup

Cool the soup to room temperature before storing. Keep soup in airtight containers in the fridge for up to 3 days. Store the toasted bread and grated cheese separately to keep them crisp and fresh. For longer storage, freeze the soup without bread or cheese for up to 3 months. Thaw overnight in the fridge and reheat gently on the stove before finishing with toast and cheese.

Tips for the Best Dutch Oven French Onion Soup

• Use a heavy Dutch oven for even heat and steady caramelizing.
• Slice onions evenly so they cook at the same rate.
• Cook onions low and slow for the best sweet, deep flavor.
• Stir often to prevent burning and to lift any browned bits for extra taste.
• Toast the bread until golden so it holds up under the cheese.
• Keep the cheese grated and ready to top each bowl just before broiling.

Recipe Variations (if any)

• Vegetarian: Use vegetable broth instead of beef broth and the same cooking steps.
• Cheese swap: Try Parmesan or a blend of Swiss-style cheeses if you prefer a milder flavor.
• Make it lighter: Reduce butter by half and add an extra splash of cooking liquid as needed.
• Herb change: Swap thyme for a small amount of rosemary or a bay leaf for a different aroma.
