Step‑by‑Step Instructions for One Pot French Onion Pasta
Step 1: Prepare Onions
Begin by slicing three large yellow onions into ⅛-inch rings using a sharp knife or mandoline for even thickness. This crucial step ensures that your onions caramelize nicely, enhancing the sweet flavor that will define your One Pot French Onion Pasta. Set aside the sliced onions; you’ll be using them shortly.
Step 2: Caramelize Onions
In a large 6-8 quart pot, heat a mix of 2 tablespoons of olive oil and 2 tablespoons of butter over medium heat. Add the sliced onions to the pot and cook for 30-35 minutes, stirring occasionally. The onions should turn a beautiful golden brown, releasing their natural sweetness and creating that rich flavor base for your pasta dish.
Step 3: Add Garlic and Spices
Once the onions are caramelized, add 4 cloves of minced garlic along with a pinch of red pepper flakes, 1 tablespoon of Worcestershire sauce, and 1 tablespoon of soy sauce to the pot. Stir everything together for about 30 seconds, allowing the flavors to meld and the garlic to become fragrant, enhancing the overall taste of your One Pot French Onion Pasta.
Step 4: Combine Liquids
Next, pour in 4 cups of water and add 1-2 beef bouillon cubes to the mixture. Then, take half a cup of evaporated milk and whisk it together with 2 tablespoons of cornstarch in a separate bowl until smooth, before adding it to the pot. This combination creates a base that pairs with the caramelized onions for a rich sauce.
Step 5: Cook Pasta
Bring the mixture to a rolling boil; once boiling, stir in 12 ounces of orecchiette pasta. Reduce the heat to a simmer and let it cook uncovered for 11-14 minutes. The pasta should reach al dente consistency while soaking up the wonderful flavors, forming the heart of your scrumptious One Pot French Onion Pasta.
Step 6: Incorporate Cheese
After the pasta is cooked, remove the pot from heat and stir in 1 cup of shredded Gruyere cheese and ½ cup of freshly grated Parmesan cheese. Mix well until the cheeses melt and create a creamy coating over the pasta. Taste and adjust seasoning as needed, perhaps adding more herbs or a splash of evaporated milk for consistency.
