How to Make One-Pot French Onion Pasta
Ingredients:
- 3 Tbsp. extra-virgin olive oil
- 4 large yellow onions, thinly sliced
- 2 tsp. Diamond Crystal or 1¼ tsp. Morton kosher salt, plus more
- 1 tsp. freshly ground black pepper, plus more
- 6 garlic cloves, finely chopped
- 4 tsp. chopped thyme
- ¾ cup dry white wine
- 1 lb. lumache (snail shells) or other medium shell pasta
- 1 oz. Parmesan, finely grated (about ½ cup)
- 5 Tbsp. unsalted butter
- 1 Tbsp. Dijon mustard
- 2 tsp. sugar
- 2 tsp. Worcestershire sauce
- 8 oz. Gruyère, coarsely grated (about 2 cups)
- Thinly sliced chives (for serving; optional)
Directions:
- Heat 3 Tbsp. of extra-virgin olive oil in a large (3½-qt. capacity or more) high-sided ovenproof skillet over medium-high heat. Add the thinly sliced onions, a pinch of kosher salt, and a pinch of black pepper. Cook the onions, stirring occasionally and adding 1 Tbsp. of water to prevent burning, until they become a deep mahogany color, about 30–35 minutes.
- Once the onions are caramelized, add the finely chopped garlic and chopped thyme. Cook until fragrant, about 1 minute. Pour in ¾ cup of dry white wine, cooking until it reduces by half, about 3 minutes. Then, add 5½ cups of water and bring to a simmer.
- Add 1 lb. of lumache (snail shells) or another medium shell pasta, stirring often to prevent sticking, and cook until the pasta has absorbed most of the liquid and is al dente, about 10–14 minutes.
- Remove the pot from heat. Stir in 1 oz. of finely grated Parmesan, 5 Tbsp. of unsalted butter, 1 Tbsp. of Dijon mustard, 2 tsp. of sugar, 2 tsp. of Worcestershire sauce, the remaining salt, and pepper until the cheese melts.
- Preheat the broiler with a rack in the upper third of the oven. Sprinkle 8 oz. of coarsely grated Gruyère over the pasta and broil until melted and golden brown, about 2–5 minutes, depending on your broiler.
- Serve topped with thinly sliced chives, if desired.

Tips to Make One-Pot French Onion Pasta
- Caramelize the Onions Well: The depth of flavor comes from well-cooked onions. Take your time to let them get a deep, golden brown color for the best taste.
- Use Quality Cheese: Opt for good quality Gruyère and Parmesan for a rich flavor. If you can, grate it fresh rather than using pre-grated cheese for better melting and taste.
- Experiment with Herbs: While this recipe calls for thyme, feel free to add other herbs like rosemary or a bay leaf for an additional layer of flavor.
- Adjust Consistency: If you find the sauce too thick, add a little more water or broth while cooking the pasta to achieve your desired creaminess.
- Make it Vegetarian: Skip the Worcestershire sauce or find a vegetarian version to keep this dish completely meat-free.
