Ingredients List

  • 8 oz (≈225 g) pasta of your choice (fettuccine or penne work well)
  • 2 medium yellow onions, thinly sliced
  • 2 Tbsp unsalted butter
  • 1 Tbsp olive oil
  • 3 cups low-sodium beef or vegetable broth
  • 1 tsp fresh thyme leaves (or ½ tsp dried thyme)
  • Salt & pepper, to taste
  • 1 cup grated Gruyère cheese (or Swiss cheese)
  • Optional: fresh parsley, chopped, for garnish

Kitchen Tools

This recipe focuses on simplicity, utilizing everyday tools that keep preparation straightforward. There’s no need for complicated gadgets—just the essentials will do.

  • Large pot for boiling pasta
  • Skillet for caramelizing onions
  • Wooden spatula or spoon
  • Measuring cups and spoons
  • Cutting board and knife

Step-by-Step Instructions


  1. Begin by bringing a large pot of salted water to a boil. Once boiling, add the pasta and cook according to package instructions until al dente. Drain and set aside, reserving about a cup of pasta water for later use.



  2. In a large skillet, heat the butter and olive oil over medium heat. Once the butter is melted, add the sliced onions. Stir occasionally and let them cook for about 15 minutes, or until they are golden brown and fragrant. The aroma will fill your kitchen, evoking the warmth of a cozy café.



  3. When the onions are nicely caramelized, pour in the broth and add the thyme. Bring the mixture to a gentle simmer and let it cook for about 5 minutes, allowing the flavors to meld. Season with salt and pepper to taste.



  4. Stir in the cooked pasta, mixing well to coat the noodles in the broth and onions. If the mixture seems dry, add a small amount of the reserved pasta water until the desired consistency is reached.



  5. Remove the skillet from heat and sprinkle the grated Gruyère cheese evenly over the pasta. Cover the skillet for a few minutes, allowing the cheese to melt and become gooey.



  6. Once the cheese has melted, give everything a gentle stir and serve warm. Garnish with freshly chopped parsley, if desired, for a pop of color.


Pro Tips

  • For a deeper flavor, consider adding a splash of white wine to the onions while they caramelize.
  • If you prefer a vegetarian option, simply substitute vegetable broth for beef broth.
  • This dish can accommodate various toppings, like crispy fried shallots or extra herbs, for added texture and flavor.

What to Serve With Easy French Onion Pasta

Pairing this Easy French Onion Pasta with complementary sides can enhance the overall dining experience. A simple arugula salad, lightly dressed with olive oil and balsamic vinegar, offers a refreshing contrast to the richness of the pasta. The peppery greens balance the sweetness of the caramelized onions, making each bite truly delightful.

A slice of crusty French bread is another excellent companion. Its rustic texture is perfect for sopping up the creamy sauce, ensuring that no flavor goes to waste. For an added touch, toast the bread and top it with a light sprinkle of cheese before serving.

Finally, consider a glass of Sauvignon Blanc. Its crisp acidity helps to cut through the richness of the cheese and broth, making it a refreshing choice to accompany your meal.
