Description

This One Pot French Onion Pasta transforms the comforting flavors of French onion soup into a creamy pasta dish. Made with caramelized onions, mushrooms, and orecchiette pasta, it’s cozy, hearty, and perfect for both weeknights and special occasions.


Ingredients

1/4 cup olive oil

3 yellow onions, thinly sliced

4 garlic cloves, minced

8 oz cremini mushrooms, sliced

1 tbsp fresh thyme

1/2 cup dry white wine

2 tbsp all purpose flour

2 cups beef broth (or vegetable broth)

2 cups water

12 oz dried orecchiette or other short cut pasta

1 tbsp sherry vinegar

Salt and freshly ground black pepper, to taste

Fresh herbs and toasted breadcrumbs, for serving (optional)


Instructions

  1. Heat olive oil in a large skillet over medium heat. Add onions and a pinch of salt. Cook, stirring often, until deeply caramelized, about 25–30 minutes.
  2. Stir in garlic, mushrooms, and thyme. Cook for 3–4 minutes, until mushrooms begin to soften.
  3. Deglaze with white wine and add flour, cooking for 2–3 minutes until slightly thickened.
  4. Pour in broth and water, season with salt and pepper, and bring to a boil.
  5. Add pasta and cook for 8–10 minutes, or until al dente.
  6. Remove from heat and stir in sherry vinegar.
  7. Garnish with fresh herbs and toasted breadcrumbs if desired. Serve warm.

Notes

Swap orecchiette with penne, rigatoni, or fusilli.

Use vegetable broth for a vegetarian version.

Add Gruyère or Parmesan cheese for extra richness.

Stir in spinach or kale for added greens.

Use balsamic vinegar instead of sherry vinegar for a slightly sweeter finish.

Store leftovers in an airtight container in the refrigerator for up to 3 days.

Reheat gently with a splash of broth or water to loosen the sauce.

Avoid freezing, as pasta and onions may lose texture.
