- 12 oz pasta (rigatoni, penne, or short pasta)
- 3 tbsp unsalted butter
- 2 tbsp olive oil
- 3 large yellow onions, thinly sliced
- 3 garlic cloves, minced
- 1 tsp sugar (to help caramelize)

- 2 cups beef or vegetable broth
- 1 cup heavy cream
- 1 ½ cups shredded Gruyère cheese (or Swiss/Mozzarella blend)
- ½ cup Parmesan cheese, grated
- Fresh parsley, chopped (for garnish)
🧑🍳 Instructions
- Caramelize the Onions – In a large skillet, heat butter and olive oil over medium-low. Add onions, sugar, salt, and pepper. Cook low and slow, stirring often, for 25–30 minutes until golden brown and deeply caramelized.
- Deglaze the Pan – Stir in garlic and thyme. Add white wine (if using) and scrape up brown bits. Let it simmer until the liquid mostly reduces.
- Make the Sauce – Pour in broth and cream, stir well, and bring to a gentle simmer. Cook 5–7 minutes until slightly thickened.
- Cook the Pasta – While sauce simmers, cook pasta in salted boiling water until al dente. Reserve ½ cup pasta water.
- Combine – Add drained pasta into the onion cream sauce. Stir in Gruyère and Parmesan until melted and creamy. If needed, add reserved pasta water for a silkier sauce.
- Serve – Garnish with parsley and extra Parmesan. Serve hot, preferably with crusty bread.
💡 Tips for the Best French Onion Pasta

- Gruyère gives that authentic French onion flavor, but mozzarella or Swiss also work.
- Add a splash of balsamic vinegar with the wine for extra depth.
- For a baked version, transfer to a baking dish, sprinkle with more cheese, and broil until bubbly.
