Introduction
This Vegan Caramelized Onion Pasta is a rich and flavorful dish perfect for a cozy weeknight dinner. Sweet caramelized onions combined with sun-dried tomatoes and creamy vegan sauce create a comforting meal that’s both satisfying and easy to prepare.

Ingredients
- 1 tbsp olive oil
- 2 yellow onions, thinly sliced
- Water, for deglazing the pan
- 5 cloves garlic, sliced
- 2 tsp Italian seasoning
- 1/2 tsp red pepper flakes, optional
- 1/4 cup julienned sun-dried tomatoes, jarred packed in oil
- 2 tbsp balsamic glaze
- 1 tbsp soy sauce
- 1/2 cup store bought or homemade vegan cream
- 2 cups dry Orecchiette pasta or 4 servings of favorite pasta (plus 1 cup reserved pasta water)
- 1/4 cup freshly minced parsley
- Salt and pepper to taste
Instructions
- Step 1: Fill one large pot with water for the pasta and set aside. Heat a large skillet over medium heat, then add the olive oil to warm. Once warm, add the sliced onions with a pinch of salt. Sauté, stirring frequently, for about 5 minutes until brown streaks appear on the pan surface. Add 1-2 tablespoons of water to deglaze the pan, stirring into the onions. Continue cooking, adding water as needed to prevent sticking or burning, until onions are deep golden brown, about 15 minutes.
- Step 2: Add the sliced garlic, Italian seasoning, and optional red pepper flakes to the pan. Sauté with the onions until the garlic is cooked and the onions turn jammy, about 3-4 minutes. Deglaze the pan with splashes of water as needed.
- Step 3: While onions cook, bring the prepared pot of water to a boil. Salt generously and cook the pasta according to package instructions. Reserve 1 cup of pasta water before draining.
- Step 4: Stir the sun-dried tomatoes, balsamic glaze, soy sauce, vegan cream, and 1/2 cup of reserved pasta water into the onions. Mix well, then fold in the drained pasta and minced parsley. Add more pasta water to reach your desired creaminess.
- Step 5: Serve the pasta warm on its own or paired with your favorite protein, such as roasted chickpeas or tofu.
Tips & Variations
- For deeper flavor, cook the onions low and slow to ensure they caramelize without burning.
- Use gluten-free pasta if preferred to accommodate dietary needs.
- Add a squeeze of fresh lemon juice before serving to brighten the flavors.
- Roasted nuts like pine nuts or walnuts make a nice crunchy topping.
Storage
Store leftover pasta in an airtight container in the refrigerator for up to 3 days. Reheat gently on the stove with a splash of water or vegan cream to restore creaminess. Avoid microwaving without adding moisture, as the pasta may dry out.
