Description

Creamy One Pot French Onion Pasta blends classic French comfort with quick weeknight convenience. Caramelized onions and rich broth create a silky sauce that will transport you to a charming Parisian bistro in minutes.


Ingredients

Scale

Main Ingredients:

  • 12 ounces (340 grams) pasta (spaghetti or fettuccine)
  • 3 large yellow onions, thinly sliced
  • 4 cups (960 milliliters) beef or vegetable broth
  • 1 cup (240 milliliters) shredded Gruyere cheese

Dairy and Seasoning Ingredients:

  • 3 tablespoons (45 grams) butter
  • 1/2 cup (120 milliliters) heavy cream
  • 3 garlic cloves, minced
  • Salt and pepper, to taste

Cooking Ingredients:

  • 1 tablespoon (15 milliliters) olive oil
  • 2 tablespoons (16 grams) all-purpose flour
  • Fresh thyme or parsley for garnish

Instructions

  1. Caramelize onions in a large pot with butter and olive oil over medium heat for approximately 20 minutes, developing rich golden-brown color and deep flavor.
  2. Introduce minced garlic and sauté briefly, then sprinkle flour to create a smooth roux, stirring continuously for one minute to eliminate raw flour taste.
  3. Gradually stream chicken broth into the pot, whisking consistently to prevent lumps and create a silky base for the pasta sauce.
  4. Add uncooked pasta directly into the liquid, allowing it to simmer and absorb the flavorful broth while cooking until perfectly tender, gently stirring to prevent sticking.
  5. Lower heat and incorporate heavy cream, creating a luxurious texture while stirring in shredded Gruyère cheese until completely melted and sauce becomes velvety smooth.
  6. Taste and adjust seasoning with salt and freshly ground black pepper, ensuring balanced flavors throughout the dish.
  7. Finish by garnishing with fresh thyme or chopped parsley, adding a bright, aromatic touch to the rich, creamy pasta.
  8. Serve immediately while hot, allowing the cheese to stretch and showcase the dish’s comforting, indulgent qualities.

Notes

  • Caramelize onions slowly over medium-low heat to develop rich, deep flavor without burning.
  • Stir flour thoroughly to prevent lumps and create a smooth, silky sauce base.
  • Use room temperature cream and cheese for smoother, more even melting and consistent texture.
  • Swap Gruyère with other melty cheeses like Emmental or white cheddar for different flavor profiles and dietary needs.
