Ingredients

• 2 tablespoons unsalted butter
• 1 tablespoon olive oil
• 3 large yellow onions sliced thin
• 1 teaspoon kosher salt
• ½ teaspoon black pepper
• 1 tablespoon fresh thyme leaves or 1 teaspoon dried thyme
• 2 teaspoons balsamic vinegar
• 3 cloves garlic minced
• 4 cups low sodium beef broth or vegetable broth
• 8 ounces uncooked fettuccine or linguine
• ½ cup heavy cream
• 1 cup shredded Gruyère cheese
• ¼ cup grated Parmesan cheese
• Chopped parsley for garnish

Equipment

• Large heavy-bottomed pot or Dutch oven
• Wooden spoon or silicone spatula
• Chef’s knife
• Cutting board
• Measuring cups and spoons

Instructions

1. Step 1: Heat the butter and olive oil in a large heavy-bottomed pot over medium heat. Once the butter has melted and starts to foam slightly, add the thinly sliced onions along with salt and pepper.
2. Step 2: Stir the onions gently but often for 25 to 30 minutes. You want them slow-cooked and deeply golden — this step builds the foundation of flavor, so do not rush. If the onions start to brown too quickly, reduce the heat slightly.
3. Step 3: Stir in the thyme, balsamic vinegar, and minced garlic. Sauté for 1 to 2 minutes, just until fragrant. The vinegar adds depth and brings a subtle brightness that really balances the sweetness of the onions.
4. Step 4: Pour in the broth and increase the heat to bring it to a gentle boil. While it heats, use your spoon to stir up any of the flavorful bits stuck to the bottom of the pot.
5. Step 5: Add the fettuccine or linguine directly into the boiling broth. Stir often while the pasta simmers uncovered for 10 to 12 minutes, or until it’s al dente. Most of the liquid should be absorbed by the end, leaving behind a richly flavored base.
6. Step 6: Reduce the heat to low. Stir in the cream, Gruyère, and Parmesan until the cheeses melt and the sauce becomes velvety smooth. This is when the dish transforms into something indulgent and cozy — utterly irresistible.
7. Step 7: Taste and adjust with more salt or pepper if needed. Serve warm, topped with chopped parsley and a little extra Parmesan if you’d like. Each bowl is pure French-inspired bliss.

Serving and Storage Tips

Refrigerate any leftovers in an airtight container for up to 4 days. When reheating, add a splash of broth or cream to loosen the noodles and restore the creamy consistency. This dish reheats well on the stovetop over low heat or in the microwave.

While you can freeze it, the texture is best enjoyed fresh or within a few days of preparing. To freeze, cool the pasta completely and transfer to a freezer-safe container. Thaw overnight in the fridge before reheating. You can also prep the caramelized onions ahead of time and store them in the fridge for up to 3 days, cutting down your cooking time significantly.
