Step‑by‑Step Instructions for French Onion Pasta
Step 1: Prep Onions
Begin by peeling and thinly slicing the large white onion. Aim for uniform, thin slices to ensure even cooking and caramelization. As you work, prepare a large sauté pan over low to medium heat, ready to transform these simple onions into a sweet base for your French onion pasta.
Step 2: Caramelize Onions
In the heated pan, pour in 6 tablespoons of olive oil, then add the sliced onions. Sauté over low heat for about 15-20 minutes, stirring occasionally, until the onions soften and turn a light golden hue. This slow process is key to achieving the rich flavors that will define your creamy French onion pasta.
Step 3: Add Ingredients
Once the onions have softened, incorporate 3 tablespoons of butter, along with 1 teaspoon of salt and 1 teaspoon of black pepper. Continue to cook for another 20 minutes, stirring often to ensure they caramelize evenly and deepen in color to a rich, golden brown. This step is crucial for a delicious flavor foundation.
Step 4: Incorporate Flavorings
Stir in 3 minced garlic cloves, 1 tablespoon of balsamic vinegar, and 1 teaspoon of tamari. Sauté everything together for about 2 minutes until the garlic is fragrant and the mixture glistens. This addition will bring a lovely depth of flavor that enhances the overall taste of your French onion pasta.
Step 5: Make Sauce
Sprinkle 3 tablespoons of plain flour over the caramelized onions, stirring quickly to coat. Then, pour in 1 cup of dry white wine, scraping the bottom of the pan to deglaze any tasty bits. Allow the mixture to cook for 5-8 minutes, reducing the wine until it thickens and the alcohol evaporates, creating a rich sauce.
Step 6: Cook Pasta
Add 1 liter of vegetable stock and 225g of uncooked farfalle pasta to the sauce. Stir well, cover the pan, and let it simmer gently for about 10 minutes. Stir occasionally to prevent sticking, allowing the pasta to absorb the flavorful sauce while reaching the perfect al dente texture.
Step 7: Final Touches
Once the pasta is cooked, stir in 60ml of double cream and 60g of grated mature cheddar cheese. Mix until the cheese melts and creates a creamy, luscious coating over the pasta. Serve your flavorful French onion pasta hot, garnished with additional cheese and freshly cracked black pepper for an indulgent finish.

Make Ahead Options
These Creamy French Onion Pasta bowls are perfect for busy weeknights when meal prep is essential! You can caramelize the onions and prepare the sauce up to 3 days in advance. Simply sauté the onions and all flavorings up through Step 5, then let it cool and store it in an airtight container in the fridge to maintain freshness. When you’re ready to enjoy, cook your pasta and combine it with the prepped sauce, adding the cream and cheese just before serving to ensure it’s as delicious as freshly made. With this make-ahead strategy, you’ll have a comforting meal ready to savor in no time!
