Here’s how you can make this delicious twist on a French classic.

Ingredients Needed

Pasta: Use a hearty, slightly thicker pasta that can hold up to the sauce, such as pappardelle, fettuccine, or even penne.
Onions: Yellow onions are your best bet. You’ll need about 4 large ones, thinly sliced.
Butter: About 2 tablespoons for sautéing the onions. The butter adds richness and depth.
Olive Oil: A couple of tablespoons to help cook the onions and prevent them from burning.
Beef Broth: Preferably low-sodium to keep the flavors balanced without being too salty.
White Wine: A dry white wine adds acidity and a little sweetness to balance out the richness.
Thyme: Fresh thyme is ideal for its aromatic, earthy flavor that complements the onions.
Garlic: A couple of cloves, finely chopped, for that extra depth of flavor.
Gruyère Cheese: The classic cheese for French Onion Soup-mildly nutty and melty. Shredded, for topping the pasta.
Parmesan Cheese: Adds a bit of sharpness and a savory punch to the dish.
Flour: A small amount to help thicken the sauce, creating that velvety consistency you crave in French Onion Soup.
Salt & Pepper: To season the broth and pasta to taste.

Cooking Instructions

Cook The Pasta
- Start by boiling salted water in a large pot and cook your pasta according to package instructions, making sure to undercook it by about 2 minutes since it will continue to cook in the sauce. Drain the pasta and set it aside, saving a cup of pasta water.
Caramelize The Onions
- In a large skillet, heat up the butter and olive oil over medium heat.
- Add the sliced onions and a pinch of salt. Stir occasionally, letting the onions cook slowly, caramelizing them for about 25-30 minutes. Be patient-the slower, the better. The goal is to get them golden brown and soft.
Deglaze The Pan
- Once the onions are caramelized, add the chopped garlic and cook for another 1-2 minutes until fragrant.
- Pour in the white wine and use a wooden spoon to scrape up any browned bits on the bottom of the pan-this is where a lot of the flavor lives.
Make The Sauce
- Sprinkle in the flour, stirring constantly to make a roux (this will help thicken the sauce). Let it cook for about 1 minute.
- Gradually add the beef broth, stirring until the sauce starts to thicken. Let it simmer for about 5-10 minutes.
Combine The Pasta And Sauce
- Add the cooked pasta into the skillet, tossing it in the sauce. If the sauce is too thick, add a splash of the reserved pasta water until you reach your desired consistency.
- Stir in the thyme, salt, and pepper to taste.
Finish With Cheese
- Once the pasta is coated in the delicious sauce, sprinkle a generous amount of grated Gruyère and Parmesan cheese over the top. Stir until the cheese is melted and gooey.
Serve
- Serve your French Onion Soup Pasta immediately while it’s still hot, and top with extra cheese if desired.

Ingredient Insights

Onions: The star of the show in French Onion Soup, onions bring a natural sweetness when caramelized. Yellow onions work best because they have a perfect balance of sweetness and depth.
Gruyère Cheese: This cheese is a must for French Onion Soup dishes. It has a firm texture and a slightly nutty, salty flavor that becomes wonderfully gooey when melted, making it ideal for this pasta.
Beef Broth: The richness of beef broth imparts that deep, savory base you expect from French Onion Soup, enhancing the overall taste of the dish. If you prefer a lighter version, you can substitute chicken broth, but beef gives it that authentic French flavor.
Wine: A dry white wine like Sauvignon Blanc or Chardonnay brightens the dish, cutting through the richness while adding a hint of fruitiness.

Expert Tips

Caramelizing the Onions: Don’t rush this step! Let the onions cook low and slow. This is where all the flavor comes from. Stir occasionally to avoid burning but give them enough time to release their natural sugars and turn golden brown.
Adding Pasta Water: Don’t forget to save some of the pasta cooking water! It helps to thicken the sauce and helps everything come together beautifully.
Cheese Meltdown: To make the cheese melt even more smoothly, you can toss the shredded Gruyère with a little bit of flour before adding it to the pasta. This helps it bind with the sauce and creates a more even, creamy texture.
Adjusting Consistency: If you prefer a more brothy, soup-like dish, don’t hesitate to add extra broth or wine. For a thicker pasta dish, you can cut back a bit on the liquid.

Recipe Variations

Vegetarian Version: Swap the beef broth for vegetable broth and skip the cheese for a dairy-free option. You can also add mushrooms for an earthy flavor that mimics the richness of the beef.
Add Protein: For a more filling meal, try adding cooked chicken, beef, or sausage. Saute the protein with the onions to infuse some additional flavor into the dish.
Gluten-Free: Use gluten-free pasta and ensure your broth and other ingredients are gluten-free to make this dish accessible to those with dietary restrictions.
Herb Variations: While thyme is traditional, you can experiment with rosemary or even a touch of sage for a different flavor profile. Fresh herbs are key to bringing out the flavors of the soup in the pasta version.

Final Words

French Onion Soup Pasta is an indulgent dish that takes all the best qualities of the beloved French classic and turns them into a pasta experience that’s equally comforting and impressive. From the deep, sweet caramelized onions to the melty, cheesy goodness, each bite feels like a warm hug in a bowl.

Whether you’re making it for a weeknight dinner or a special occasion, this dish is sure to impress. It’s rich, it’s flavorful, and it’s a fun twist on a classic. And the best part? It’s so easy to make, yet feels fancy enough to serve guests.
