What You’ll Need:
- 4 large yellow onions (about 3 pounds), thinly sliced No worries if you don’t have yellow onions—I often use sweet onions in my Dutch Oven French Onion Soup for a milder flavor.
- 4 tablespoons unsalted butter You can swap half the butter for olive oil if you want to lighten things up.
- 2 tablespoons extra-virgin olive oil This helps in browning the onions evenly.
- 1 teaspoon salt Essential for drawing out onion moisture and enhancing flavor.
- 1/2 teaspoon freshly ground black pepper
- 1 teaspoon granulated sugar This little addition speeds up caramelization.
- 2 cloves garlic, minced For depth in flavor; if you’re out of fresh garlic, 1/2 teaspoon garlic powder works.
- 1/3 cup dry white wine (optional) Adds brightness; I usually keep a small bottle for cooking.
- 8 cups beef broth or vegetable broth Look for low-sodium to control the saltiness.
- 1 tablespoon Worcestershire sauce Gives savory depth.
- 1 bay leaf
- 1 teaspoon fresh thyme leaves or 1/2 teaspoon dried thyme
- French bread baguette, sliced I find a day-old baguette works best to hold up under the cheese.
- 6 ounces Gruyère cheese, grated You can substitute Swiss or mozzarella if you need.
This Dutch Oven French Onion Soup keeps costs reasonable by using pantry staples and fresh but common ingredients. The onions are the real stars here, and caramelized slowly, they transform into a rich, flavorful base. For storage, if you have leftovers, keep the soup separate from the bread and cheese and store in airtight containers in the fridge for up to 3 days. Reheat gently on the stove, add fresh bread, and broil your cheese before serving again.
If you’re short on time, you can buy pre-sliced onions, but I like slicing my own because it gives the onion pieces just the right thickness for that signature caramelized onions soup texture. Preparing your ingredients ahead makes Dutch oven cooking smoother and more enjoyable.
Let’s Make It Together:
- Prep your onions: Thinly slice about 4 large onions. It’s okay if the slices aren’t perfect—this isn’t a fine dining place, but a comforting kitchen spot.
- Heat your Dutch oven: Place it over medium heat, then melt 4 tablespoons of butter with 2 tablespoons of olive oil.
- Cook the onions: Add the onions, salt, and sugar to the pot. Stir frequently for about 15 minutes, reducing heat if needed so they don’t burn. This is where I used to rush my Dutch Oven French Onion Soup—taking your time here really pays off.
- Caramelize slowly: Let the onions cook down gently for another 30-40 minutes, stirring every few minutes. Your kitchen will smell amazing when your Dutch Oven French Onion Soup is ready here—the deep sweetness and golden color tell you it’s spot on.
- Add garlic and wine: Stir in the minced garlic and cook for 1 minute. Then pour in the white wine, scraping the bottom of the pot to loosen any flavorful bits.
- Add broth and herbs: Pour in 8 cups of beef or vegetable broth, Worcestershire sauce, bay leaf, and thyme. Bring to a simmer and cook for 30 minutes. While that simmers, you can set the table or prepare your bread slices.
- Prepare your bread: Toast baguette slices until lightly browned. I like to do this under the broiler for a quick, crisp texture.
- Assemble and broil: Ladle soup into oven-safe bowls, place toasted bread on top, and sprinkle generously with Gruyère cheese. Place under the broiler until cheese is bubbly and golden.
- Serve immediately: Dutch Oven French Onion Soup is best enjoyed hot. Serve with a simple green salad or crusty bread for an easy meal.
From start to finish, this Dutch Oven French Onion Soup takes about 1 hour 30 minutes, mostly unattended cooking time. Don’t worry if your soup looks darker than pictures you’ve seen; a rich caramelized onions soup is all part of the charm.
If you’re curious, I once tried this French onion soup recipe in an Instant Pot to save time. It’s good, but I still prefer the slow cooked soup flavor you get from Dutch oven cooking. That extra patience really shines through.
How to Serve & Enjoy:
I usually serve my Dutch Oven French Onion Soup in individual oven-safe bowls, topped with melty cheese and crusty bread. It’s perfect for chilly evenings or casual weekend dinners. It pairs wonderfully with a crisp green salad or roasted vegetables to balance the rich, savory flavors.
For a crowd, you can easily double the recipe and keep the soup warm in your Dutch oven on low heat, topping each bowl right before serving. Friends and family appreciate how this comfort food soup feels special without feeling fussy.
If you want a little twist, try adding a splash of sherry instead of white wine or swapping in smoked gouda for the cheese once in a while. Seasonal variations with fresh thyme from the garden add brightness, and it’s lovely in fall and winter months.
Leftovers? Turn your Dutch Oven French Onion Soup into a simple midday meal by adding leftover soup to a pot with cooked pasta or rice for a hearty lunch. Or scoop it over baked potatoes for a comforting change.
This soup reminds me of another favorite, the turmeric ginger chicken noodle soup, which also gives that cozy, slow cooked soup vibe but with a totally different punch.
Your Questions Answered:
- Can I make this Dutch Oven French Onion Soup ahead of time? Absolutely. The flavors deepen when the soup rests overnight. Store soup, bread, and cheese separately, then assemble just before reheating and broiling.
- What’s a good substitute for Gruyère cheese? I’ve used Swiss or mozzarella with satisfying results, though Gruyère gives the best melt and flavor. You can also try smoked cheddar for a twist.
- Can I make this soup vegetarian? Yes! Use vegetable broth and skip the Worcestershire sauce or use a vegan version to keep it vegetarian-friendly.
- How do I adjust this Dutch Oven French Onion Soup for more or fewer people? The recipe scales up well; just keep your Dutch oven size in mind. For fewer servings, halve the ingredients.
- Is it necessary to use a Dutch oven? Dutch oven cooking helps with even heat and slow caramelization, but a heavy-bottomed pot works if you don’t have one.
- Can I skip the wine in this French onion soup recipe? Yes, just add a touch more broth or a splash of vinegar for acidity. I sometimes skip it on busy nights.
- How long should I caramelize the onions for the best results? About 45 minutes to an hour is ideal. Take your time—rushing leads to uneven cooking. Also, stirring often prevents burning and spots your caramelized onions soup success.
