Full of the same wonderful savory flavors as classic French onion soup, this irresistible pasta is ideal for autumn and winter when you're in the mood for a cozy, comforting dish.

How to Make French Onion Pasta

The first step in making this gorgeous French onion pasta is to caramelize the onions. Heat the olive oil in a large skillet over medium flame. Stir in the onions and season them with salt. Sauté the onions for 20 to 30 minutes, until they turn a rich dark brown. Make sure to stir the onions often, so they don't burn. Caramelizing takes time – be patient. This is what will give your French onion pasta its amazing flavor.

Once the onions are dark brown, add the garlic, thyme, and mushrooms. Cook for a few minutes, then pour in the wine. Scrape any browned bits up from the bottom of the pan – this will add even more flavor to your pasta. Whisk in the flour and cook until the raw flour smell is gone and the sauce has thickened.

Stir in broth and water and season well with salt and pepper. Bring the mixture to a boil and add the pasta. Cook the pasta to al dente following directions on the box. Remove from heat and stir in vinegar, then serve with cheesy garlic bread, dinner bread, or sourdough.

Tips for Making One-pot French Onion Pasta

To make a vegetarian or vegan-friendly French onion pasta, swap beef broth for vegetable broth.

You can use other types of pasta. Penne, rigatoni, farfalle, and fusilli are all excellent options.

Make a heartier French onion pasta by adding chicken breast or shrimp.

Use dry white wine like an unoaked Chardonnay, Pinot Grigio, or Sauvignon Blanc.

Yellow onions are fantastic in this recipe, but sweet onions like Vidalia are beautiful in French onion pasta. Red onions work, too, or you can use a mixture of different types of onion for a more complex, flavorful dish.

For a gluten-free French onion pasta, use gluten-free pasta and a cornstarch slurry in place of flour.

Add some freshly grated parmesan, cheddar, or gruyere to your pasta to take it to the next level.

How to Store French Onion Pasta

Keep your French onion pasta in an airtight container in the fridge for up to 3 days. Reheat in the microwave or a pot on the stove until heated through.
