Description
A simple pasta dish featuring sweet caramelized onions and melted Gruyere cheese, inspired by classic French Onion Soup.
Ingredients
Scale
- 1 pound pasta (such as penne or rigatoni)
- 3 large yellow onions, thinly sliced
- 4 tablespoons unsalted butter
- 1 tablespoon olive oil
- 1 teaspoon salt
- 1/2 teaspoon black pepper
- 2 cloves garlic, minced
- 1/2 cup dry white wine (optional)
- 4 cups beef broth
- 1/4 cup all-purpose flour
- 1 cup heavy cream
- 8 ounces Gruyere cheese, shredded
- 1/4 cup grated Parmesan cheese
- 2 tablespoons fresh parsley, chopped (for garnish)
Instructions
- Cook pasta according to package directions until al dente. Reserve 1 cup of pasta water before draining.
- In a large skillet or Dutch oven, melt butter with olive oil over medium-low heat. Add the sliced onions, salt, and pepper.
- Cook the onions slowly, stirring occasionally, for 30 to 40 minutes until deeply browned and sweet. This slow cooking creates the caramelization.
- Add the minced garlic to the onions and cook for 1 minute until fragrant.
- If using wine, pour it in and scrape up any browned bits from the bottom of the pan. Let it reduce by half.
- Sprinkle the flour over the onions and stir well for 1 minute.
- Gradually whisk in the beef broth until smooth. Bring the mixture to a simmer and cook until the sauce thickens slightly, about 5 minutes.
- Reduce heat to low. Stir in the heavy cream.
- Add the drained pasta to the sauce. Toss to coat. If the sauce is too thick, add reserved pasta water, a little at a time, until you reach your desired consistency.
- Stir in most of the Gruyere and Parmesan cheese until melted and creamy.
- Serve immediately, topped with the remaining Gruyere and fresh parsley.
Notes
- For deeper flavor, use low-sodium beef broth.
- If you do not have Gruyere, Swiss cheese is a suitable substitute.
- You can skip the wine and use an extra 1/2 cup of beef broth.
