5 from 8 reviews

One Pot French Onion Pasta gives you the flavors of French Onion Soup in a filling, slightly creamy pasta recipe. Start with caramelized onions in a large pot then add the remaining ingredients, including the uncooked pasta. Everything cooks up in the one pot for easy clean up!

Ingredients

  • 1/4 cup unsalted butter
  • 3 large yellow onions, halved and thinly sliced
  • 1/4 cup sherry cooking wine
  • 1/2 cup white wine,  prefer a dry white wine like a Sauvignon Blanc
  • 4-5 sprigs fresh thyme, plus extra for garnish
  • Kosher salt and ground black pepper
  • 1 lb uncooked rigatoni
  • 4 cups beef broth or stock
  • 1 teaspoon Worcestershire sauce
  • 1/2 cup freshly grated parmesan, plus more for serving
  • 1/2 cup heavy cream, or half and half

Instructions

  1. Caramelize Onions - Heat up a large dutch oven or pot over medium heat and melt the butter. Add the thinly sliced onions and cook over medium for about 5 minutes until starting to soften. Reduce the heat to medium-low and cook for about 30 minutes until caramelized. Stir the onions occasionally to keep them from sticking to the bottom.
  2. Deglaze Pan - Pour in the sherry and white wine to the onions. Scrape any bits off the bottom and let cook for a couple minutes so the wine reduces slightly.
  3. Add Pasta Ingredients - Add the sprigs of thyme (you can use twine to tie them together in a bundle), a pinch of salt, heavy pinch of pepper, the uncooked pasta, beef broth, and Worcestershire sauce. Stir to combine.
  4. Boil - Bring the broth to a boil, give one big stir, and immediately lower the heat and cover the pot so it simmer. Allow to simmer for about 10 minutes, or until the liquid is absorbed and the pasta is al dente.
  5. Finish Pasta - Turn off the heat and remove and discard the thyme sprigs. Stir in the heavy cream and parmesan cream until combined. Taste and adjust the salt and pepper, if needed.
  6. Serve - Serve the pasta in bowls. I like to top with fresh parmesan and a light sprinkle of extra thyme leaves.

Notes

Leftover pasta can be stored in an airtight container in the fridge for up to 4 days or frozen for up to 3 months. Reheat leftovers in the microwave or in a pot on the stove - you can add a splash of cream or broth to loosen things up.
