What You Need
These ingredients make this Dutch Oven French Onion Soup absolutely crave-worthy! Let’s get into the list:
- 6 large yellow onions, thinly sliced (Splurge on sweet yellow onions for that perfect mellow sweetness)
- 4 tablespoons unsalted butter (Butter adds that silky richness essential for slow caramelized onions)
- 2 tablespoons olive oil (Combines with butter so onions caramelize evenly without burning)
- 1 teaspoon sugar (This helps coax out the natural sweetness in the onions—it’s a secret weapon)
- 4 cloves garlic, minced (Adds a subtle punch that layers into the soup’s savory base)
- 1/2 cup dry white wine (Grab this from the international aisle — it deglazes the pot and lifts flavor beautifully)
- 8 cups beef broth soup (For the deepest flavor, go with a high-quality beef broth or make your own)
- 1 tablespoon Worcestershire sauce (Brings umami without overpowering the broth)
- Fresh thyme sprigs (Nothing beats the fresh herb aroma in this soup)
- Salt and freshly ground black pepper to taste
- 1 baguette, sliced into 1/2 inch rounds (Crusty baguette slices are a must for that satisfying crunch)
- 2 cups Gruyère cheese, grated (Gruyère is the best choice for that melted cheese topping that bubbles and browns perfectly)
Pro Tip: If you want to save some time, slice your onions ahead and keep them in an airtight container—they’ll stay fresh for a day or two. And if you’re feeling fancy, add a little splash of sherry instead of wine for a subtle twist.
This Dutch Oven French Onion Soup gets even better when you use homemade beef broth soup, but if that’s a lot of work, go for a good store-bought broth—and I always recommend tasting as you go. Add more salt or pepper depending on your taste. I like to go heavy on the butter and cheese because, come on, those elements turn this soup into a total drool-worthy experience.

How to Make It
This step is where the magic happens with your Dutch Oven French Onion Soup! Buckle up—slow caramelized onions are the heart of this dish, so patience pays off.
- Melt butter and olive oil in your Dutch oven over medium-low heat. Toss in the sliced onions and a sprinkle of salt. The secret? Let them cook slowly, stirring every 8-10 minutes. You want them soft and turning this gorgeous golden brown without rushing or burning. This is the slow caramelized onions stage where all the flavor develops. This part takes about 45 minutes, but trust me, it’s worth every second.
- Add sugar to encourage caramelization and stir in the minced garlic for the last 5 minutes. Your kitchen will start smelling like pure heaven. This smell alone had my friends asking for the recipe!
- Deglaze the pot with white wine. Pour it in and scrape all those caramelized bits off the bottom—that’s pure flavor gold for your Dutch Oven French Onion Soup.
- Pour in the beef broth soup, Worcestershire sauce, and toss in the thyme sprigs. Bring everything to a gentle simmer, let it cook together for 30 minutes. This melds all those flavors into the classic French onion soup base we’re aiming for.
- While the soup simmers, toast your crusty baguette slices. Pop them under the broiler or in the oven until just golden and crisp.
- Ladle the soup into oven-safe bowls. Place toasted baguette slices on top, then pile on that Gruyère cheese for the melted cheese topping. Load it up—you want that glorious golden bubbly finish.
- Broil for 3-5 minutes until the cheese is bubbling and lightly browned. Keep a close eye so it doesn’t burn but gets that irresistible crust.
This Dutch Oven French Onion Soup comes together in about two hours total, but it feels like such a treat every step of the way. Pro tip: if you want even deeper flavor, make the broth base a day ahead and let everything marry overnight in the fridge before broiling with the cheese.

Your Questions Answered
Q: How do I make this Dutch Oven French Onion Soup extra flavorful?
A: Slow caramelized onions are the key here—don’t rush this step! Also, deglaze with wine to get all those stuck-on bits. Using fresh herbs like thyme and quality beef broth soup makes a noticeable difference. I sometimes add a splash of Worcestershire sauce for that umami punch.
Q: Can I meal prep this Dutch Oven French Onion Soup?
A: Yes! Make the soup base ahead, store it in the fridge for up to 3 days. Keep the baguette slices and cheese separate, then assemble and broil right before serving to keep that melted cheese topping fresh and perfect.
Q: What’s the best way to reheat Dutch Oven French Onion Soup without losing quality?
A: Reheat gently on the stove to avoid overcooking the onions. When ready to serve, toast fresh baguette slices and add Gruyère cheese just before broiling to get that bubbly top again.
Q: Can I use other cheeses for the melted cheese topping?
A: Gruyère is classic because it melts beautifully, but Emmental or a mix of mozzarella and Parmesan also work well for that luscious stretch and flavor.
Q: My onions burned—how to avoid this?
A: Lower the heat and stir often during caramelization—it’s all about patience. Using a thick-bottomed Dutch oven really helps distribute heat gently.
Q: Can I make this soup vegetarian?
A: Absolutely. Swap beef broth soup for mushroom or vegetable broth and keep the slow caramelized onions and garlic. You’ll get great depth of flavor!
Q: How can I make crusty baguette slices that don’t get soggy?
A: Toast the slices first, and add them on top right before broiling with cheese. This keeps them crispy under the melty cheese topping.
