Chef's Pro-Tips
- Don't Rush the Caramelization: Low and slow cooking allows the natural sugars in the onions to break down into rich, sweet complexity that defines authentic French onion flavor.
- Deglaze the Fond: The browned bits stuck to the bottom of your Dutch oven are pure concentrated flavor. Scraping them into the wine and broth builds an incredible umami sauce.
- Gruyère is Essential: While Swiss or provolone works in a pinch, authentic alpine Gruyère provides that earthy, nutty melt and irresistible cheese pulls.

Step-by-Step Instructions
Caramelize the Onions
Melt 2 tablespoons of butter with 1 tablespoon of olive oil in a large Dutch oven or deep heavy skillet over medium-low heat. Add the sliced onions and 1/2 teaspoon kosher salt. Cook slowly, stirring every 3 to 4 minutes, for 20 to 25 minutes until the onions turn rich, jammy, and deeply golden brown. (If they brown too quickly, turn heat down and add a splash of water).
Bloom Aromatics & Deglaze
Add minced garlic and fresh thyme to the caramelized onions, stirring for 1 minute until fragrant. Pour in dry white wine to deglaze the pot, scraping up all the savory browned bits (fond) stuck to the bottom. Simmer for 2 minutes until the wine reduces by half.
Simmer Pasta in Rich Broth
Stir in beef bone broth, Worcestershire sauce, and remaining 1/2 teaspoon salt. Bring to a rolling boil over medium-high heat. Add uncooked rigatoni, stirring well. Reduce heat to medium-low, cover with a lid slightly cracked, and simmer for 12 to 14 minutes, stirring every couple of minutes, until pasta is al dente and broth has reduced into a glossy sauce.
Melt Cheeses & Emulsify Cream
Turn heat to low. Stir in remaining 1 tablespoon butter, heavy cream, grated Parmigiano-Reggiano, and 1 cup of the shredded Gruyère cheese. Stir continuously for 2 minutes until cheese melts smoothly into the luxurious onion sauce.
Broil Top & Garnish
Scatter remaining 1/2 cup shredded Gruyère over the pasta. Place under the oven broiler (or cover with lid off-heat for 3 minutes) until the cheese bubbles into a golden, gooey crown. Garnish with fresh thyme leaves and cracked black pepper. Serve piping hot straight from the pot.

Yes! Simply replace the white wine with an equal amount of beef broth plus 1 teaspoon of apple cider vinegar or white wine vinegar for acidity.
Medium ridged shapes like rigatoni, cascatelli, penne rigate, or medium pasta shells trap the glossy caramelized onion sauce and melted Gruyère beautifully.
It is best enjoyed fresh off the stove. For leftovers, store in an airtight container for up to 3 days and reheat in a skillet with a splash of broth or cream to restore its velvety texture.
