Description

This French Onion Tortellini recipe combines the rich, caramelized flavors of classic French onion soup with tender cheese tortellini. The dish features slowly caramelized onions and a savory broth sauce, topped with melted Gruyère and Parmesan cheeses, making it a comforting and elegant meal perfect for any occasion.


Ingredients

Scale

Onion Sauce

  • 3 large yellow onions (thinly sliced)
  • 3 tablespoons butter
  • 2 tablespoons olive oil
  • 2 cloves garlic (minced)
  • 1 teaspoon fresh thyme leaves
  • 1 tablespoon all-purpose flour
  • 1 cup beef broth (or vegetable broth for a vegetarian version)
  • 1/2 cup dry white wine
  • Salt and freshly ground black pepper to taste

Tortellini and Topping

  • 1 package (20 oz) cheese tortellini
  • 1 cup grated Gruyère cheese
  • 1/2 cup grated Parmesan cheese
  • Chopped fresh parsley for garnish


Instructions

  1. Prepare the base: In a large, heavy-bottomed pot or Dutch oven, melt the butter with olive oil over medium heat.
  2. Caramelize the onions: Add the sliced onions and cook, stirring occasionally, for about 30-40 minutes until they become deeply caramelized and golden brown, which is key to developing that rich French onion flavor.
  3. Add aromatics: Stir in the minced garlic and fresh thyme leaves, cooking for another minute until fragrant.
  4. Make a roux: Sprinkle the flour over the onions and cook for 1-2 minutes, stirring constantly to avoid lumps and to toast the flour slightly.
  5. Add liquids: Slowly pour in the beef broth and white wine, stirring continuously to combine, and let the mixture simmer for 5 minutes until the sauce thickens slightly.
  6. Cook tortellini: While the onion mixture simmers, cook the tortellini in a separate pot of salted boiling water following the package instructions until al dente, then drain and set aside.
  7. Combine tortellini and onion sauce: Add the cooked tortellini to the onion mixture, gently tossing to coat the pasta evenly with the rich sauce.
  8. Prepare for broiling: Transfer the combined tortellini and onion mixture to a large oven-safe skillet or baking dish.
  9. Add cheese topping: Evenly sprinkle the grated Gruyère and Parmesan cheeses over the top.
  10. Broil: Place under the oven broiler for 2-3 minutes, watching carefully, until the cheese melts, bubbles, and develops a light golden crust.
  11. Garnish and serve: Remove from the oven, allow to cool slightly, then garnish with chopped fresh parsley before serving.

Notes

  • For a vegetarian version, substitute beef broth with vegetable broth.
  • Be patient when caramelizing onions; this step is essential for flavor depth.
  • Use a sharp Gruyère cheese for best melting and flavor.
  • Watch the broiler carefully to avoid burning the cheese topping.
  • This dish pairs beautifully with a crisp green salad or steamed vegetables.
