The deep, satisfying flavor of classic French onion soup is translated into this weeknight-friendly, comforting pasta. The sauce and pasta cook together in one pot, achieving complex, savory depth with rich caramelized onions, beef broth, and creamy Gruyère cheese.
3 large yellow onions, thinly sliced (about 570 grams)
4 tablespoons unsalted butter
1 tablespoon olive oil
1 teaspoon dried thyme
1 quarter teaspoon freshly ground black pepper
1 teaspoon kosher salt, plus more for seasoning
4 cups beef broth, low-sodium
1 cup dry white wine, like Sauvignon Blanc
8 ounces small pasta shape (campanelle, penne, or farfalle)
1 half cup heavy cream
1 cup shredded Gruyère cheese
1 quarter cup shredded Parmesan cheese
1. Melt the butter and oil, then cook sliced onions, salt, and pepper over medium-low heat until deep golden brown and reduced in volume (30 to 40 minutes).
2. Increase heat. Pour in white wine and scrape up any browned bits (fond). Let wine reduce until almost evaporated. Stir in thyme.
3. Pour in beef broth and bring to a gentle boil. Add the uncooked pasta and stir well.
4. Reduce heat to medium-low. Simmer, uncovered, stirring, until the pasta is al dente and the liquid has reduced to a thick, creamy sauce (15 to 20 minutes).
5. Remove the pot from the heat. Stir in the heavy cream, Gruyère, and Parmesan cheeses until the sauce is smooth and glossy.
6. Serve hot, adjusting seasoning as needed.
The key is slow caramelization; rushing this step makes the flavor flat. Use high-quality, low-sodium beef broth for the best depth. Avoid pre-shredded cheese for a smoother sauce. If you prefer a slightly sweeter note, stir in one teaspoon of balsamic vinegar during deglazing.
