Ingredients
Scale
For the Caramelized Onion Sauce
- 2 tbsp unsalted butter
- 2 tbsp olive oil
- 2 large yellow onions, thinly sliced
- 1 tsp salt
- ½ tsp black pepper
- 1 tsp sugar
- ½ tsp dried thyme
- ¼ cup dry white wine (optional)
- 2 cloves garlic, minced
- 1 tbsp all-purpose flour
- 2 cups beef or vegetable broth
- ½ cup heavy cream
For the Pasta and Cheese
- 8 oz pasta (penne, rigatoni, or your choice)
- 1 cup shredded Gruyère cheese
- ¼ cup grated Parmesan cheese
For Garnish
- Fresh thyme or parsley, for garnish (optional)
Instructions
- Caramelize the Onions: Heat butter and olive oil in a large skillet over medium heat. Add the thinly sliced onions along with salt, black pepper, sugar, and dried thyme. Cook the onions, stirring occasionally, for 25-30 minutes until they become deeply golden brown and caramelized, developing rich sweetness and flavor.
- Deglaze & Build the Sauce: Pour in the dry white wine, if using, and cook for about 2 minutes until the wine has mostly evaporated and the pan is deglazed. Stir in the minced garlic and sauté for 1 minute until fragrant.
- Add the Flour: Sprinkle the all-purpose flour over the onion mixture and stir well to coat the onions. This will help thicken the sauce.
- Add Broth and Cream: Gradually pour in the beef or vegetable broth while stirring constantly to avoid lumps. Let the sauce cook and thicken for a few minutes. Then, add the heavy cream and reduce the heat to low, allowing the sauce to gently simmer and blend together.
- Cook the Pasta: While the sauce simmers, cook the pasta according to package directions until al dente. Drain the pasta thoroughly once cooked.
- Combine Pasta and Sauce: Add the drained pasta directly into the skillet with the onion sauce. Stir well to coat the pasta evenly with the rich sauce.
- Add the Cheese: Stir in the shredded Gruyère and grated Parmesan cheese until they melt completely and the sauce becomes creamy and cohesive.
- Serve & Garnish: Serve the French Onion Pasta hot, garnished with fresh thyme or parsley if desired for an added herbal freshness and visual appeal.
Notes
- Using a combination of beef or vegetable broth adds depth to the sauce; choose according to preference or dietary needs.
- The white wine is optional but adds a nice acidity and complexity; substitute with broth if preferred.
- Be careful to cook the onions slowly to ensure proper caramelization without burning.
- Gruyère cheese gives a wonderful melt and flavor typical of French onion soup, but you can substitute with Swiss cheese if needed.
- This dish pairs well with a simple green salad or crusty bread.
