This comforting French Onion Pasta combines the rich, caramelized flavors of classic French onion soup with tender orecchiette pasta, crispy bacon, and a creamy cheese sauce. Simmered in beef stock and finished with a bubbly Gruyère and Parmesan topping, this one-pot dish is perfect for a cozy dinner.


Ingredients

Scale

Pasta and Broth

  • 1 lb orecchiette pasta
  • 4 cups beef stock
  • ½ cup dry white wine
  • 1 tsp fresh thyme
  • 1 tsp fresh rosemary
  • salt and pepper to taste

Vegetables and Aromatics

  • 3 large yellow onions, thinly sliced
  • 4 cloves garlic, minced

Meat and Dairy

  • 6–8 slices bacon, chopped
  • ½ cup heavy cream
  • 2 cups shredded Gruyère or Swiss cheese, divided
  • ½ cup grated Parmesan

Oils and Fats

  • 1 tbsp olive oil

Instructions

  1. Caramelize Onions: Heat olive oil in a large Dutch oven over medium-low heat. Add sliced onions and a pinch of salt. Cook slowly, stirring occasionally, and add small splashes of water as needed to prevent burning, until the onions are deeply caramelized, about 20-25 minutes.
  2. Cook Bacon: Remove the caramelized onions and set aside. In the same pot, cook chopped bacon over medium heat until crispy. Drain excess grease leaving about 1 tablespoon in the pot.
  3. Sauté Garlic and Combine: Add the caramelized onions back to the pot along with minced garlic. Cook until the garlic is fragrant, about 1-2 minutes.
  4. Deglaze Pot: Pour in dry white wine and scrape the bottom of the pot to loosen any browned bits for added flavor.
  5. Add Pasta and Liquids: Add orecchiette pasta, beef stock, fresh thyme, rosemary, and black pepper to the pot. Stir to combine, making sure the pasta is evenly submerged in the broth.
  6. Simmer Pasta: Bring the liquid to a low simmering boil, then cover with a lid, reduce heat to low, and cook until the pasta is tender and most of the liquid is absorbed, about 10 minutes.
  7. Add Cream and Cheese: Stir in heavy cream and 1 cup of shredded Gruyère cheese until melted and incorporated into a creamy sauce.
  8. Bake Cheese Topping: Top the pasta with the remaining Gruyère and grated Parmesan. Cover with the lid to melt the cheese or place the pan under a broiler for a few minutes until the cheese layer is bubbly and golden brown.

Notes

  • Adding small splashes of water during onion caramelization helps soften onions and prevents burning while building flavor.
  • Use low heat when caramelizing onions to avoid bitterness and develop deeper flavor.
  • Gruyère cheese provides the most authentic French onion taste, but Swiss cheese is a good substitute.
  • If broiling cheese, watch closely to prevent burning.
  • Reserve some bacon grease for extra flavor but discard excess to prevent greasiness.
