Ingredients
Scale
Onion and Butter Base
- 2 large white onions, sliced thin
- 5 tbsp butter, divided
Herbs and Spices
- 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)
Liquids and Pasta
- 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
- 1 lb short pasta (rigatoni preferred)
Cheese
- 1 cup shredded Gruyere cheese (use freshly shredded from block)
Instructions
- Caramelize the Onions: Thinly slice the onions. In a large soup pot, melt 3 tablespoons of butter over low to medium heat. Sauté the onions for 8-10 minutes until softened. Add 1/4 cup red wine and stir frequently until the liquid is absorbed. Repeat with another 1/4 cup red wine and continue to sauté and stir. Continue slow cooking for about 30 minutes total, adding the remaining 2 tablespoons of butter if needed to prevent dryness. Aim for richly caramelized onions without burning.
- Add Herbs and Spices: Stir in fresh thyme leaves, minced garlic, and cayenne pepper. Keep the heat low and cook an additional 5-7 minutes to deepen the flavors without charring the ingredients.
- Combine Pasta and Liquids: Pour in the last 1/4 cup of red wine, heavy cream, beef broth, and Worcestershire sauce. Add the rigatoni pasta and stir well. Leave the pot uncovered and cook, stirring frequently, until most of the liquid is absorbed and the pasta is al dente, about 10-11 minutes.
- Add Cheese and Adjust Seasoning: Mix in 3/4 cup of shredded Gruyere cheese thoroughly into the pasta mixture. Taste and add more salt or cheese as preferred. Check pasta doneness 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 browns. If the pasta is slightly undercooked (al dente), bake for 8-10 minutes first, then broil for 2 minutes to finish.
- Serve: Remove from the oven and optionally top with extra cheese and fresh thyme leaves. Serve hot and enjoy your creamy, flavorful French onion pasta!
Notes
- Use freshly shredded Gruyere for best melting and flavor.
- Adjust cayenne pepper to your preferred spice level or omit for milder taste.
- Keep stirring the onions frequently during caramelizing to avoid burning.
- If you prefer a vegetarian version, substitute beef broth with vegetable broth and omit Worcestershire sauce or use a vegetarian alternative.
- Check pasta’s doneness carefully before baking to ensure proper texture.
- Broiling times may vary depending on your oven; watch closely to avoid burning the cheese topping.
