Step‑by‑Step Instructions for Vegan Caramelized Onion Pasta
Step 1: Cook Pasta
Bring a large pot of water to a rolling boil over high heat. Once boiling, salt the water generously and add your pasta of choice. Cook according to the package instructions until al dente, typically about 8-10 minutes. Reserve 1 cup of the pasta water before draining, then set the drained pasta aside while you prepare the sauce.
Step 2: Caramelize Onions
In a large skillet, heat 2 tablespoons of olive oil over medium heat. Add the sliced onions along with a pinch of salt to help them soften. Sauté for about 5 minutes, stirring occasionally, until they start to brown. Add a splash of water to deglaze the pan, scraping up any browned bits, and reduce the heat slightly. Continue to cook for another 15 minutes until the onions are deeply caramelized and jammy.
Step 3: Add Aromatics
With the onions caramelized, stir in 3 minced garlic cloves, 1 teaspoon of Italian seasoning, and a pinch of red pepper flakes if desired. Sauté everything together for 3 to 4 minutes until the garlic turns fragrant and golden. This step enhances the flavor profile of your Vegan Caramelized Onion Pasta, creating a savory base for your sauce.
Step 4: Combine Ingredients
To the skillet with the aromatics, add ½ cup of chopped sun-dried tomatoes, 3 tablespoons of balsamic glaze, and 2 tablespoons of tamari. Pour in the reserved pasta water, starting with ½ cup, and stir everything together. Allow it to simmer for a few minutes so the flavors meld beautifully, resulting in a rich and savory sauce.
Step 5: Toss Pasta
Carefully add the cooked pasta into the skillet, tossing it gently to coat in the luscious sauce. Be sure to adjust the consistency with additional reserved pasta water if necessary. Cook together for another minute over low heat, ensuring the pasta is heated through and well combined with the sauce.
Step 6: Serve
Once well mixed, remove the skillet from heat. Serve your Vegan Caramelized Onion Pasta immediately, or place it in a serving dish. This dish is fantastic on its own, but feel free to pair it with roasted chickpeas or sautéed tofu for added protein. For any leftovers, store them in an airtight container in the fridge for up to 4 days.

Make Ahead Options
These Vegan Caramelized Onion Pasta preparations are perfect for busy cooks looking to save time during the week! You can caramelize the onions and store them in an airtight container in the refrigerator for up to 3 days. Additionally, cook the pasta al dente and toss it with a little olive oil to prevent sticking before storing it in the fridge, where it can also last up to 3 days. When it’s time to serve, simply reheat the onions in a skillet, add the pasta, and adjust with reserved pasta water or a splash of vegan cream if needed. This way, you’ll enjoy a quick, comforting meal that’s just as delicious as freshly made!
