This rich and comforting pasta dish is inspired by classic French onion soup—packed with caramelized onions, earthy mushrooms, savory pancetta, and melted Gruyère cheese, all tossed in a creamy, herb-infused sauce. Perfect for a cozy night in or an elegant dinner with friends!

Ingredients

For the Sauce:

1 cup beef broth
½ cup chicken broth (or use more beef broth)
1 cup half and half
1 teaspoon hot sauce
1 teaspoon Worcestershire sauce
1 teaspoon Dijon mustard (or ½ tsp mustard powder)
1 teaspoon dried parsley
½ teaspoon dried thyme
½ teaspoon dried oregano

For the Pasta:

1 tablespoon olive oil
8 oz. white button mushrooms, sliced
Salt and pepper, to taste
4 oz. pancetta, diced
⅔ cup dry white wine (see notes for substitutions)
3 tablespoons butter
3 medium yellow onions, thinly sliced (about 15 oz.)
4 cloves garlic, minced
3 tablespoons all-purpose flour
½ cup Gruyère cheese, shredded (or sub mozzarella)
½ cup Parmesan cheese, freshly grated
¾ lb. orecchiette pasta (or your favorite pasta shape)

Instructions

1. Prepare the Sauce:

In a large measuring cup, whisk together the beef broth, chicken broth, half and half, hot sauce, Worcestershire sauce, Dijon mustard, and dried herbs. Set aside.

2. Sauté Mushrooms and Pancetta:

Heat olive oil in a large skillet over medium-high heat. Add the mushrooms and sauté for 3 minutes. Sprinkle with salt to enhance their flavor. Add the pancetta and cook for another 3–4 minutes until crisp. Remove from the skillet and set aside.

3. Deglaze the Pan:

Turn off the heat. Add the white wine to the skillet and turn the heat back to medium. Use a spatula to scrape the flavorful browned bits from the bottom—this adds depth to your sauce.

4. Caramelize the Onions:

Add the butter and sliced onions to the skillet. Cook over medium heat, stirring frequently, for 10 minutes. Reduce the heat to medium-low and continue to cook for another 30–35 minutes, stirring often, until the onions are deeply golden and caramelized. If they dry out too quickly, add a splash of wine or olive oil.

5. Cook the Pasta:

While the onions are caramelizing, bring a large pot of salted water to a boil. (Add about ½ tablespoon kosher salt.) Cook pasta to al dente according to package instructions, then drain.

6. Build the Sauce:

Once the onions are caramelized, stir in the minced garlic and cook for 1 minute. Sprinkle in the flour and stir continuously for 2 minutes to form a roux. Slowly add the sauce mixture in small splashes, stirring constantly until smooth.

Bring to a gentle boil, then reduce to a low simmer. Let the sauce cook partially covered while the pasta finishes.

7. Finish the Dish:

Reduce heat to low. Gradually stir in the Gruyère and Parmesan cheese until melted and smooth. Return the cooked mushrooms and pancetta to the skillet and stir to combine.

Add the drained pasta gradually, mixing well until everything is evenly coated and heated through.

Yes! Prepare the dish, then refrigerate. Reheat gently on the stove or in the microwave with a splash of broth or cream to loosen the sauce.

Is this dish vegetarian?
Not as written, but you can make it vegetarian by omitting the pancetta and using vegetable broth instead of beef/chicken broth.
