The secret to this dish lies in the patience required to properly caramelize the onions. Taking the time to slowly cook them until they're deeply golden and sweet is what transforms this from a simple pasta dish into something truly special. The thyme adds an aromatic, earthy note that complements the richness of the cheese and the savory depth of the broth. Whether you choose beef or chicken broth, the pasta absorbs all those wonderful flavors as it cooks, creating a dish that's both rustic and refined.

Ingredients

• 2 large boneless, skinless chicken breasts (about 500 g), cut into bite-sized pieces
• 3 large yellow onions, thinly sliced
• 3 cloves garlic, minced
• 2 tablespoons fresh thyme leaves (or 1 teaspoon dried thyme)
• 340 g (12 oz) short pasta (penne, fusilli, or rigatoni)
• 3 tablespoons unsalted butter
• 2 tablespoons olive oil
• 1 liter (4 cups) low-sodium beef or chicken broth
• 120 ml (1/2 cup) dry white wine (optional, substitute with more broth)
• Salt and freshly ground black pepper, to taste
• 100 g (1 cup) Gruyère cheese, shredded
• 50 g (1/2 cup) mozzarella cheese, shredded
• 2 tablespoons grated Parmesan cheese

Instructions

Step 1: Cook the Chicken

Heat olive oil and 1 tablespoon butter in a large Dutch oven or deep skillet over medium heat. Add the chicken pieces, season with salt and pepper, and cook until golden and cooked through, about 6–8 minutes. Remove chicken and set aside.

Step 2: Caramelize the Onions

In the same pot, add the remaining butter. Add the sliced onions and a generous pinch of salt. Cook slowly over medium-low heat, stirring often, until onions are deeply caramelized and golden brown, about 20–25 minutes.

Step 3: Add Aromatics

Add garlic and thyme, and sauté for 1 minute until fragrant.

Step 4: Deglaze with Wine

Pour in the wine (if using) and scrape up any browned bits. Let it reduce by half, about 2–3 minutes.

Step 5: Combine and Cook Pasta

Return the chicken to the pot. Add the uncooked pasta and broth. Bring to a boil, then reduce heat to a simmer.

Step 6: Simmer Until Tender

Cover and cook, stirring occasionally, until the pasta is al dente and most of the liquid has been absorbed (about 10–12 minutes).

Step 7: Add the Cheese

Stir in Gruyère and mozzarella cheese until melted and creamy. Season with extra salt and pepper if needed.

Step 8: Optional Broil

Sprinkle with Parmesan cheese and, if desired, broil under the oven for 2–3 minutes until golden and bubbly.

Step 9: Serve

Serve hot, garnished with extra thyme.

Zusatztipps für die Zubereitung

The key to deeply caramelized onions is patience and consistent stirring. Don't rush this step by turning up the heat, as the onions can burn rather than caramelize. Use a wooden spoon to scrape up any browned bits from the bottom of the pot when deglazing with wine, as these fond pieces add incredible flavor to the sauce. If the pasta absorbs liquid too quickly during cooking, add a splash more broth to prevent sticking. For the richest flavor, use beef broth, but chicken broth works beautifully for a lighter version. Freshly grated cheese melts more smoothly than pre-shredded varieties, which often contain anti-caking agents.

Varianten und Anpassungen

For a vegetarian version, omit the chicken and use vegetable broth instead of beef or chicken broth. You can add mushrooms for extra umami depth and a meaty texture. If you can't find Gruyère, Swiss or Emmental cheese make excellent substitutes with similar nutty, melty qualities. For a lighter dish, reduce the amount of cheese or use part-skim mozzarella. You can also experiment with different pasta shapes, though short, sturdy varieties like penne, rigatoni, or fusilli work best for absorbing the sauce. Add a handful of fresh spinach or kale in the final minutes of cooking for extra nutrition and color.

Serviervorschläge

This rich, savory pasta pairs beautifully with a crisp green salad dressed with a light vinaigrette to cut through the richness. A glass of Chardonnay or a light-bodied Pinot Noir complements the cheese and caramelized onions perfectly. For a complete French-inspired meal, serve with crusty baguette slices for soaking up any extra sauce. Garnish with additional fresh thyme leaves and a crack of black pepper just before serving. Leftovers reheat wonderfully, though you may need to add a splash of broth to loosen the sauce.
