Ingredients
Scale
French Onion Base
- 2 large white onions, sliced thin
- 5 tbsp butter, divided
- 1 tbsp fresh thyme leaves
- 1/2 tbsp garlic, minced
- 1/4 tsp cayenne pepper
- 1/2 tsp salt (plus more to taste)
- 1/2 tsp pepper (adjust to taste)
- 3/4 cup dry red wine (Cabernet Sauvignon recommended, divided)
- 3.5 cups beef broth
- 1 tbsp Worcestershire sauce
- 1/4 cup heavy cream or half & half
Pasta and Cheese
- 1 lb short pasta (rigatoni preferred)
- 1 cup shredded Gruyere cheese (freshly shredded from block, divided)
Instructions
- Caramelize the Onions: Thinly slice the onions and heat 3 tablespoons of butter in a large soup pot over low-medium heat. Sauté the onions for 8-10 minutes until softened. Add 1/4 cup of red wine, stirring frequently until fully absorbed. Repeat with another 1/4 cup of red wine. Continue slow cooking and stirring for about 30 minutes total, adding the remaining 2 tablespoons of butter as needed to keep the onions from drying out. The goal is deeply caramelized onions without burning.
- Add Herbs and Spices: Stir in fresh thyme leaves, minced garlic, and cayenne pepper. Continue cooking over low heat for another 5-7 minutes to develop rich flavors while avoiding any charring.
- Combine Pasta and Liquids: Pour in the last 1/4 cup of red wine, heavy cream, beef broth, and Worcestershire sauce directly into the pot. Add the rigatoni pasta and stir well to combine. Keep the pot uncovered and cook, stirring frequently, until the liquid is mostly absorbed and the pasta reaches al dente texture, about 10-11 minutes.
- Add Cheese and Adjust Seasoning: Mix in 3/4 cup of the shredded Gruyere cheese thoroughly into the pasta mixture. Taste and adjust salt or cheese amount as preferred. Check the doneness of the pasta to determine the next step.
- Bake with Cheese Topping: Transfer the pasta mixture into an oven-safe baking dish. Sprinkle the remaining Gruyere cheese evenly on top. If the pasta is fully cooked and tender, broil for 3 minutes until the cheese melts and develops a golden brown crust. If the pasta is slightly undercooked (al dente), bake for 8-10 minutes first, then broil for 2 minutes to finish.
- Serve: Remove from oven and optionally top with extra cheese and fresh thyme leaves for garnish. Serve hot and enjoy the creamy, savory flavors of this French onion pasta dish.
Notes
- Use freshly shredded Gruyere cheese for the best melting and flavor results.
- Adjust cayenne pepper to taste if you prefer less heat.
- Red wine adds depth; Cabernet Sauvignon is recommended but any dry red wine works.
- Keep the heat low while caramelizing onions to avoid burning and ensure rich flavor development.
- The pasta absorbs flavor from the braising liquid, so stirring frequently is essential to prevent sticking and promote even cooking.
- This recipe uses beef broth for a classic French onion flavor; for vegetarian, substitute with vegetable broth (though this alters the traditional taste).
