Step‑by‑Step Instructions for One Pot French Onion Pasta
Step 1: Caramelize Onions
Begin by heating 2 tablespoons of olive oil and 2 tablespoons of butter in a large Dutch oven over medium heat. Add the sliced yellow onions and cook, stirring occasionally, for about 30-35 minutes until they are caramelized and golden brown. Keep an eye on the heat, adjusting it as needed to prevent burning, allowing the natural sweetness to bloom.
Step 2: Add Flavor
Once your onions are beautifully caramelized, stir in 4 minced garlic cloves, 1 tablespoon of Worcestershire sauce, 1 tablespoon of soy sauce, and a pinch of red pepper flakes. Cook this mixture for an additional 30 seconds, stirring constantly until the garlic is fragrant and the flavors meld, creating a rich base for your One Pot French Onion Pasta.
Step 3: Combine Liquids
Pour in 4 cups of water and half a can of evaporated milk into the pot. In a small bowl, whisk 1 tablespoon of cornstarch with the remaining evaporated milk before adding it to the pot as well. Stir in 2 teaspoons of beef bouillon and your choice of herbs and spices, ensuring everything is well combined for a delicious broth base.
Step 4: Cook Pasta
Bring the mixture to a rolling boil, then add 8 ounces of your chosen pasta, stirring gently. Reduce the heat to a simmer and cook uncovered for 20-25 minutes, frequently stirring to avoid sticking. The pasta should be al dente, absorbing the flavors while leaving some delicious liquid in the pot for a creamy finish.
Step 5: Incorporate Cheese
Once the pasta reaches perfect doneness, remove the pot from heat. Gradually stir in 1 cup of shredded Gruyere cheese and ½ cup of freshly grated Parmesan until both cheeses melt into a luscious, creamy sauce. Taste, adjust seasoning if needed, and garnish with freshly chopped parsley for an inviting finish to your One Pot French Onion Pasta.

Expert Tips for One-Pot French Onion Pasta
-
Caramelization is Key: Slow-cook your onions over medium heat to develop their sweetness; rushing this step can lead to bitterness.
