Step‑by‑Step Instructions for One-Pot French Onion Pasta
Step 1: Slice Onions
Begin by slicing the yellow onions into ⅛-inch rings, ensuring evenness for uniform cooking. This step is crucial as these sweet onions will caramelize beautifully, providing the rich flavor base for your One-Pot French Onion Pasta. Set them aside as you prepare to sauté.
Step 2: Caramelize Onions
In a large Dutch oven, heat a mixture of olive oil and butter over medium heat. Add the sliced onions and stir regularly for about 30-35 minutes, until they turn golden brown and deeply caramelized. This patience pays off as the sweetness intensifies, creating the heart of your dish’s flavor.
Step 3: Add Flavorings
Once the onions are beautifully caramelized, stir in the minced garlic, red pepper flakes, Worcestershire sauce, and soy sauce. Allow these ingredients to cook together for about 30 seconds, stirring frequently to release their aromas. This will deepen the flavor of your French Onion Pasta.
Step 4: Add Liquids
Next, pour in the water and half of the evaporated milk, stirring well to combine. In a small bowl, whisk together the cornstarch with the remaining milk, then add to the pot alongside the beef bouillon and fresh herbs. This mixture will create a wonderfully rich broth, essential for flavoring the pasta.
Step 5: Cook Pasta
Bring the mixture to a boil over high heat, then add your chosen pasta. Reduce heat to a gentle simmer, cooking uncovered for 20-25 minutes. Stir occasionally, ensuring even cooking and preventing sticking. The pasta should be al dente and surrounded by a luscious cream sauce.
Step 6: Finish with Cheese
Once the pasta is cooked to your liking, remove the pot from heat and stir in the freshly grated Gruyere and Parmesan cheese. Keep stirring until the cheeses melt into the sauce, creating a creamy, comforting texture for your One-Pot French Onion Pasta. Taste and adjust seasoning as needed before serving.
