How to Make Caramelized French Onion Pasta
Let’s dive into the deliciousness of making Caramelized French Onion Pasta!
Caramelize Those Onions: Begin by slicing three medium yellow onions thinly. Heat two tablespoons of olive oil in a large skillet over medium-low heat. Add the onions and a pinch of salt, stirring occasionally until they turn golden brown and fragrant—about 20 to 25 minutes.
Add Garlic: Once your onions are perfectly caramelized, toss in four minced garlic cloves. Sauté them together until aromatic—just about one minute will do—ensuring not to burn the garlic.
Pasta Time: While your onions are working their magic, cook 12 ounces of spaghetti or fettuccine according to package instructions until al dente. Remember to reserve about one cup of pasta water before draining!
Create the Sauce: Pour in one cup of vegetable broth and bring everything to a gentle simmer. Add half a cup of heavy cream and stir until combined beautifully. The mixture should look creamy and inviting!
Toss It All Together: Add your drained pasta directly into the skillet with the caramelized onion sauce mixture. Toss gently and add reserved pasta water as needed until you achieve that dreamy consistency—everything should meld together nicely.
Add Finishing Touches: Finally, remove from heat and stir in freshly grated Parmesan cheese and chopped fresh thyme leaves. Season generously with salt and pepper before serving hot!
