Ingredients
For the Caramelized Onions
- 2 large onions, thinly sliced
- 3 tablespoons olive oil
- 1 tablespoon butter
- 1 teaspoon sugar
- 1/2 teaspoon salt
For the Sauce
- 3 cloves garlic, minced
- 1/2 cup white wine (optional)
- 1/2 cup vegetable or chicken broth
- 1/2 cup heavy cream
- 1/2 cup grated Parmesan cheese
For the Pasta
- 12 ounces pasta (such as fettuccine or spaghetti)
- Salt and pepper, to taste
For Serving
- Fresh parsley, chopped (for garnish)
- Additional grated Parmesan cheese (optional)
Instructions
- Cook the Pasta: Bring a large pot of salted water to a boil. Add the pasta and cook according to the package instructions until al dente. Drain and set aside.
- Caramelize the Onions: In a large skillet, heat the olive oil and butter over medium heat. Add the sliced onions, sugar, and 1/2 teaspoon salt. Cook slowly, stirring occasionally, for 25-30 minutes until the onions are golden brown and caramelized. Lower the heat if necessary and be patient to prevent burning.
- Add Garlic: Stir in the minced garlic and cook for 1-2 minutes until fragrant, letting it blend with the sweet onions.
- Deglaze the Pan: (Optional) Pour in the white wine, scraping up any browned bits from the bottom of the pan. Simmer for 2-3 minutes until most of the wine has evaporated, concentrating the flavors.
- Add Broth and Cream: Pour in the vegetable or chicken broth and heavy cream. Stir well, and simmer for about 5 minutes until the sauce thickens slightly and is creamy.
- Add Cheese: Mix in the grated Parmesan cheese until it melts and is fully incorporated into the sauce. Taste and season with additional salt and pepper if needed.
- Combine Pasta and Sauce: Add the cooked pasta to the skillet. Toss well to coat every strand in the caramelized onion sauce, ensuring even distribution.
- Serve: Divide the pasta onto serving plates. Garnish with chopped fresh parsley and extra Parmesan cheese if you like. Enjoy immediately!
