Step‑by‑Step Instructions for One Pot French Onion Pasta
Step 1: Sauté Onions
In a large pot, heat 2 tablespoons of olive oil over medium heat. Add 3 thinly sliced onions and sprinkle with a pinch of salt. Sauté for 15-20 minutes, stirring occasionally, until the onions are golden brown and caramelized, releasing their natural sweetness. This step is crucial for achieving the delightful base flavor of your One Pot French Onion Pasta.
Step 2: Add Garlic and Thyme
Once the onions are beautifully caramelized, add 2 minced garlic cloves and 1 teaspoon of fresh thyme. Cook for an additional 1-2 minutes, stirring frequently, until fragrant. The garlic should be lightly golden but not burnt, infusing the onions with a rich aroma that elevates the flavor profile of your One Pot French Onion Pasta.
Step 3: Cook Pasta
Pour in 4 cups of vegetable broth and bring the mixture to a rolling boil. Add 12 ounces of your favorite pasta, stirring to combine. Reduce the heat to a gentle simmer and cook uncovered for 8-10 minutes, or until the pasta is al dente. Stir occasionally to prevent sticking, ensuring that each bite of your One Pot French Onion Pasta is perfectly cooked.
Step 4: Stir in Cream
Once the pasta is cooked, gradually mix in 1 cup of heavy cream. Continue to simmer for 3-5 minutes, allowing the sauce to thicken and creaminess to envelop the pasta. Keep stirring gently to ensure an even, velvety consistency that marries perfectly with the flavors of the caramelized onions and garlic in your One Pot French Onion Pasta.
Step 5: Melt Cheese
Remove the pot from heat and fold in 1 1/2 cups of grated Gruyère cheese, stirring until fully melted and smooth. Season with salt and pepper to taste, adjusting as needed. The cheese will add a luscious richness, making your One Pot French Onion Pasta a truly comforting, indulgent dish.
