How to Make Vegan Caramelized Onion Pasta
Follow these simple steps to prepare this delicious Vegan Caramelized Onion Pasta:
Step 1: Cook the Pasta
Bring a large saucepan of water to a boil. Once boiling, salt it generously and add the pasta. Cook according to the package instructions for an al dente texture.
Step 2: Reserve Pasta Water
Before draining the cooked pasta, scoop out at least 1 cup (240 mL) of pasta water and set it aside. This starchy water will help bind the sauce later.
Step 3: Caramelize the Onions
In a 12-inch skillet or Dutch oven over medium-high heat, add the olive oil. Once it’s hot, toss in the sliced onions and season with salt and pepper. Stir frequently and cook until you see a light brown fond forming on the pan’s surface, about 5 minutes. Don’t forget to add some water to deglaze the pan.
Step 4: Develop the Flavor
Keep the onions cooking, adding a splash of water every few minutes and stirring to prevent burning. Continue until the onions are deeply golden brown, about 15 minutes.
Step 5: Add Garlic and Spices
Reduce the heat to medium and stir the garlic into the pan. Cook for another 5-10 minutes until the onions are fully caramelized and the garlic is soft and golden. Then mix in the red pepper flakes and oregano, stirring for about 30 seconds.
Step 6: Mix in the Sauce Ingredients
Add the tomato paste and stir constantly until it caramelizes further, darkening in color for about 2-3 minutes. Then incorporate the tamari, nutritional yeast, and chopped sundried tomatoes until well combined. Lower the heat to keep everything warm.
Step 7: Combine with Pasta
Ladle a few spoons from the reserved pasta water into the onion mixture. Transfer the hot cooked pasta to the skillet and use tongs to swirl the pasta into the sauce, adding more pasta water as necessary until every noodle is coated, which typically takes about 3-4 minutes.
Finish your meal with a sprinkle of pine nuts and freshly chopped parsley if desired. Enjoy a plate of this Vegan Caramelized Onion Pasta and feel the delightful warmth spread from your tummy to your fingertips! This dish doesn’t just fill the stomach; it also fills the soul with happiness.
