Description

A hearty and deeply flavorful one-pot pasta featuring rich caramelized onions, savory mushrooms, and a splash of white wine—all coated in a silky sauce and finished with sherry vinegar for brightness.


Ingredients

1/4 cup olive oil

3 yellow onions, thinly sliced

4 garlic cloves, minced

8 ounces cremini mushrooms, sliced

1 tablespoon fresh thyme

1/2 cup dry white wine

2 tablespoons all-purpose flour

2 cups beef broth (or vegetable broth)

2 cups water

12 ounces dried orecchiette or other short cut pasta

1 tablespoon sherry vinegar

Salt and freshly ground black pepper, to taste

Fresh herbs and toasted breadcrumbs, for serving (optional)


Instructions

  1. In a large skillet or heavy pot, heat the olive oil over medium heat until shimmering. Add the sliced onions with a generous pinch of salt and cook, stirring frequently, until deeply caramelized—about 25 to 30 minutes.
  2. Add the minced garlic, sliced mushrooms, and fresh thyme. Sauté for 3 to 4 minutes until mushrooms soften.
  3. Pour in the dry white wine to deglaze the pan, scraping up any browned bits. Stir in the all-purpose flour and cook for another 2 to 3 minutes until the mixture thickens slightly.
  4. Add the beef or vegetable broth and water. Season with salt and freshly ground black pepper to taste. Bring the liquid to a boil.
  5. Add the dried orecchiette (or other short pasta) and cook for 8 to 10 minutes (or until al dente, noting that timing may vary with pasta shape), stirring occasionally to prevent sticking.
  6. Turn off the heat and stir in the sherry vinegar. Adjust seasoning if needed.
  7. Serve warm, topped with fresh herbs and toasted breadcrumbs if desired.

Notes

  • Use vegetable broth for a vegetarian version and vegan broth/oil for a vegan option.
  • To deepen flavor, don’t rush the onion caramelization process.
  • Adjust vinegar to taste—it adds balance and brightness.
  • Leftovers are best eaten within 3 days; avoid freezing for best texture.
