Ingredients

Scale

Main Ingredients:

  • 8 ounces (226 grams) fettuccine pasta
  • 2 large onions, thinly sliced
  • 1 cup beef broth (or vegetable broth for vegetarian version)
  • 1 cup heavy cream
  • 1/2 cup grated Gruyere cheese
  • 1/4 cup grated Parmesan cheese

Seasoning and Aromatics:

  • 2 tablespoons butter
  • 2 cloves garlic, minced
  • 1 teaspoon thyme (fresh or dried)

Finishing Ingredients:

  • Salt to taste
  • Pepper to taste

Instructions

  1. Boil fettuccine in generously salted water for 8-10 minutes until perfectly al dente. Drain and reserve pasta, keeping it warm.
  2. Transform onions into a rich, golden masterpiece by slowly caramelizing them in butter over medium-low heat. Stir periodically to prevent burning, allowing 20-25 minutes for deep amber coloration.
  3. Introduce minced garlic and fragrant thyme to the caramelized onions, sautéing for 60 seconds to release their aromatic essence.
  4. Deglaze the skillet with robust beef broth, allowing liquid to reduce and concentrate flavors for 2-3 minutes. Incorporate heavy cream, creating a velvety base by simmering an additional 3-4 minutes.
  5. Melt Gruyere and Parmesan cheeses into the sauce, stirring until smooth and fully integrated. Season with salt and freshly cracked black pepper to enhance the depth of flavor.
  6. Gently fold cooked fettuccine into the creamy onion sauce, ensuring each strand is luxuriously coated. Allow pasta to simmer for 2-3 minutes, enabling flavors to harmonize.
  7. Present the dish immediately, optionally garnishing with additional grated cheese or delicate thyme sprigs for an elegant finishing touch.

Notes

  • Use sweet or yellow onions for the best caramelization, ensuring a deep, rich flavor profile that creates a mellow, almost nutty taste.
  • Slice onions uniformly to guarantee even cooking and prevent burning during the caramelization process.
  • Low and slow is the key when browning onions; patience helps develop complex, sweet undertones without scorching.
  • For a lighter version, substitute half-and-half instead of heavy cream and use reduced-fat cheeses to decrease overall calorie content.
