I still remember the moment I finally nailed my Dutch Oven French Onion Soup recipe. After a few attempts where the onions were undercooked or the broth wasn’t rich enough, something just clicked.

That first successful pot has since become a much-loved staple in my kitchen.
This Dutch Oven French Onion Soup has a way of making cold days feel cozy and special. It’s simple yet satisfying—a recipe that reminds me why I love baking and cooking not just for flavor, but for the joy and comfort it brings.

What You’ll Need for This Dutch Oven French Onion Soup:
Here’s what you’ll gather to make this Dutch Oven French Onion Soup come to life:
- 6 large yellow onions (about 3 pounds), thinly sliced—caramelized onions are the star here, so don’t rush this step.
- 4 tablespoons unsalted butter—I always add a bit extra because it helps with the slow browning of those onions.
- 1 tablespoon olive oil—a little helps keep the butter from burning during slow simmering.
- 2 cloves garlic, minced—adds depth without overpowering the soup.
- 8 cups beef broth, preferably low sodium—this broth gives the soup its rich base. Don’t have beef broth? A mix of beef and chicken broth works beautifully here too.
- 1/2 cup dry white wine (optional)—I like it for a subtle brightness, but you can skip it if you prefer.
- 1 teaspoon fresh thyme or 1/2 teaspoon dried thyme—fresh is lovely but dried is a handy, budget-friendly swap.
- 2 bay leaves
- Salt and freshly ground black pepper, to taste
- 1 baguette or rustic bread, sliced and toasted—this will make the rustic bread topping that holds the melty Gruyere cheese.
- 2 cups Gruyere cheese, shredded—this cheese melts perfectly, giving that classic, rich finish.
You can find these ingredients at most grocery stores. This Dutch Oven French Onion Soup is affordable because it uses simple staples but delivers a fancy taste. A quick prep tip: slice those onions a little thick, and take your time caramelizing. It’s worth the patience. And if you want to save time during busy days, you can caramelize onions a day ahead and refrigerate them.
I always keep leftover beef broth frozen in portions, so I’m never short when making this soup. It’s a little habit that makes assembling Dutch Oven French Onion Soup a breeze whenever I want.
How to Make This Dutch Oven French Onion Soup:
Let’s make this Dutch Oven French Onion Soup step-by-step, just like we’re cooking together in the same kitchen.
- Start with the onions: In a large Dutch oven, heat butter and olive oil over medium heat. Add the sliced onions and a pinch of salt. Here’s where slow simmering does its magic. Stir frequently as the onions soften and turn a golden caramelized color over 30-40 minutes. This step is key for deep flavor, so don’t rush.
- Add garlic: Once onions are beautifully caramelized, stir in minced garlic and cook for another minute until fragrant. The smell here is heavenly.
- Deglaze with wine: Pour in the white wine, scraping any browned bits off the bottom of the pot. Let it simmer for 2-3 minutes until mostly evaporated. If you’re skipping wine, just move to the next step.
- Add broth and herbs: Pour in the beef broth, and add thyme and bay leaves. Bring the soup to a gentle boil, then reduce heat to low and let it simmer with the lid slightly ajar for about 30 minutes. Slow simmering allows those flavors to meld perfectly.
- Prepare rustic bread topping: While the soup simmers, toast your sliced baguette in the oven until golden. This rustic bread topping is the base for your cheese and adds a delightful crunch.
- Final assembly: Remove bay leaves. Ladle the soup into oven-safe bowls. Place a few pieces of toasted rustic bread on top, then heap on shredded Gruyere cheese.
- Broil to finish: Place bowls on a baking sheet and broil in the oven until the cheese bubbles and browns slightly (3-5 minutes). Watch closely so it doesn’t burn!
From start to finish, this Dutch Oven French Onion Soup takes about 1.5 hours, but the reward is that rich, cozy bowl of goodness. While it simmers, take a moment to tidy your kitchen or enjoy a cup of tea—trust me, the kitchen will smell inviting and warm.
If your onions start to brown too quickly or stick, just lower the heat. This step taught me to be patient—it’s the difference between caramelized onions and burnt bits. A little stirring keeps everything perfect.
How I love this recipe is how each step unfolds slowly with such comforting flavors, making it a true kitchen joy.
Serving Your Dutch Oven French Onion Soup:
I love serving this Dutch Oven French Onion Soup piping hot right from the oven. There’s something so satisfying about those golden, bubbly Gruyere cheese tops with rustic bread soaking up the flavorful broth.
This soup pairs beautifully with a simple green salad dressed in vinaigrette—something fresh to balance the rich soup.

Common Questions About This Dutch Oven French Onion Soup:
Let’s talk through some questions I hear all the time about Dutch Oven French Onion Soup.
- Can I make this ahead of time? Absolutely! You can caramelize the onions and make the broth a day ahead. Store them separately in the fridge and combine them before reheating. The soup even tastes better after resting.
- What’s a good substitute for Gruyere cheese? Swiss cheese or even mozzarella can work in a pinch, but Gruyere’s flavor and meltiness are hard to beat.
- Can I use chicken broth instead of beef broth? You can, but beef broth gives the soup its classic depth. A mix of beef and chicken broth is a good compromise if that’s what you have.
- How do I adjust for different pan sizes? If you don’t have a Dutch oven, a heavy pot with a lid works. Just watch the simmering closely to prevent scorching.
- Is it okay to skip the wine? Yes! The soup still tastes wonderful without it, especially with good broth and caramelized onions.
- How thick should I slice the onions? About 1/4 inch thick is ideal—they soften well and are easier to caramelize evenly.
- Can this recipe be made vegetarian? Traditional Dutch Oven French Onion Soup is beef-based, but it’s easy to use vegetable broth and skip the wine for a delicious vegetarian version.
I’ve tried all these variations myself, and the adjustments you make can make this recipe perfectly your own. If you want more inspo, the Serious Eats French Onion Soup recipe has some fantastic ideas too.
