Ingredients

• 2 tablespoons unsalted butter
• 2 tablespoons olive oil
• 3 large yellow onions, thinly sliced
• 4 cloves garlic, minced
• 1 tablespoon fresh thyme leaves
• 1/4 cup dry white wine (optional)
• 5 cups low-sodium beef broth
• 1 tablespoon Worcestershire sauce
• 12 ounces uncooked rigatoni or other short pasta
• 1 cup shredded Gruyère cheese
• 1/4 cup heavy cream
• Salt and freshly ground black pepper, to taste
• Fresh parsley, chopped, for garnish

Directions

1. Caramelize the Onions
In a large pot, melt the butter over medium heat and add the olive oil. Toss in the sliced onions and cook them slowly, stirring frequently, until they become golden brown and deeply caramelized. This process takes about 20–25 minutes but is key to achieving the signature flavor.

2. Deglaze the Pot
Once the onions are caramelized, pour a splash of beef broth or white wine into the pot to deglaze it. Scrape up any flavorful browned bits from the bottom of the pot to enhance the dish.

3. Add the Broth and Pasta
Stir in the remaining beef broth and Worcestershire sauce. Bring the mixture to a boil, add the uncooked pasta, then reduce the heat to a simmer. Cook for 10–12 minutes, stirring occasionally, until the pasta is tender and most of the liquid has been absorbed.

4. Incorporate the Cheese
Turn off the heat and stir in the shredded Gruyère cheese until it melts into the sauce, creating a creamy, savory coating for the pasta. Mix in the heavy cream for added richness. Adjust the seasoning with salt and freshly ground black pepper to taste.

5. Garnish and Serve
Dish up the pasta hot, garnished with fresh parsley or thyme. Serve it immediately for a comforting, flavorful meal that’s sure to impress.

FAQs

Yes, substitute the beef broth with vegetable broth and ensure the Worcestershire sauce is vegetarian-friendly, as some contain anchovies.

Short pasta like rigatoni, penne, or fusilli works best as it absorbs the sauce and blends well with the onions.

Absolutely! Replace it with an equal amount of beef broth or a splash of apple cider vinegar for a similar tangy effect.

4. Can I make this recipe ahead of time?

Keep an eye on the pasta while simmering. Stir occasionally and remove it from heat as soon as it’s tender but firm to the bite (al dente).
