1 tbsp olive oil
-
3 large yellow onions, thinly sliced
-
1 tsp sugar
-
1 tsp fresh thyme (or ½ tsp dried)
-
½ cup dry white wine (or extra broth)
-
1½ cups beef broth (or vegetable broth for vegetarian)
-
1 cup heavy cream
-
1 tsp Worcestershire sauce
-
2 cups shredded Gruyère cheese, plus more for topping
-
Salt & pepper, to taste
Optional Toppings:
-
Fresh parsley, chopped
-
Parmesan cheese, for extra flavor
Instructions
-
Caramelize the Onions
In a large skillet or Dutch oven, melt butter and olive oil over medium-low heat. Add sliced onions, sugar, thyme, and a good pinch of salt and pepper.
Cook slowly for 30–40 minutes, stirring every few minutes, until the onions are deeply golden and jammy. Don’t rush this step! -
Deglaze the Pan
Pour in white wine (or broth), scraping up all the browned bits from the bottom. Simmer 2–3 minutes until mostly reduced. -
Cook the Pasta
Boil rigatoni in salted water until 1 minute shy of al dente. Drain, but don’t rinse. -
Make the Sauce
Add broth, cream, and Worcestershire sauce to the onions. Simmer 5 minutes, then reduce heat and slowly stir in 2 cups Gruyère until smooth and melted. Taste and season as needed. -
Combine
Preheat oven to 375°F (190°C). Toss cooked pasta into the onion-cheese sauce until evenly coated.
Transfer to a greased 9×13-inch baking dish (or bake right in the skillet if it’s oven-safe). -
Bake to Golden Perfection
Sprinkle generously with extra Gruyère (and Parmesan, if using).
Bake for 20–25 minutes, until bubbly and beautifully browned on top. -
Serve & Savor
Rest 5–10 minutes before serving. Garnish with chopped parsley and cracked pepper.
Serve with a crisp salad and a slice of crusty baguette — because that sauce deserves to be mopped up.
