Ingredients

Roasted Garlic:

  • 1 head garlic
  • 1 teaspoon olive oil
  • sprinkle of salt & pepper

Caramelized Onion Garlic Sauce & Pasta:

  • 8 ounces dried spaghetti or linguine, cooked according to package instructions
  • 2 Tablespoons vegan butter
  • 1 Tablespoon olive oil
  • 1 large yellow onion, thinly sliced (or 2 small onions)
  • ½ teaspoon salt
  • 2-3 teaspoons water (add as needed to deglaze the pan while caramelizing onions)
  • 1½ Tablespoons vegan Worcestershire sauce
  • 1 Tablespoon roasted garlic paste (from roasted garlic above; adjust to preference)
  • 1 teaspoon dried parsley
  • ½ cup full-fat coconut milk
  • ¼ cup starchy pasta water (reserved from cooking pasta)
  • Salt & pepper to taste (recommend at least ½ teaspoon ground black pepper)


Instructions

  1. Roast the Garlic: Preheat the oven to 400°F (200°C). Peel away the loose papery outer layers of the garlic bulb but keep the bulb intact. Slice about ¼ inch from the top to expose the cloves. Place the garlic bulb on a piece of tin foil, drizzle with olive oil, sprinkle with salt and pepper, then wrap the bulb tightly in the foil. Roast in the oven for 30-40 minutes until soft and golden.
  2. Make Roasted Garlic Paste: Remove the roasted garlic from the oven and let cool until safe to handle. Squeeze out the softened garlic cloves from the bulb and mash into a thick paste. Set aside.
  3. Cook the Pasta: While garlic is roasting, cook the spaghetti or linguine according to the package instructions. Before draining, reserve ¼ cup of the starchy pasta water to use later in the sauce. Drain the pasta and set aside.
  4. Slice Onions: Thinly slice the yellow onion (or onions) while the pasta cooks.
  5. Caramelize Onions: In a saucepan over medium heat, melt vegan butter with olive oil. Once bubbling, add the sliced onions and ½ teaspoon salt. Cook slowly, stirring every few minutes, until the onions turn deep golden brown and caramelized, about 30-40 minutes. If the pan becomes too dry or onions brown too quickly, add 1 teaspoon of water to deglaze as needed.
  6. Add Flavorings: Once onions are caramelized, stir in vegan Worcestershire sauce, roasted garlic paste (start with 1 tablespoon, adjust to taste), and dried parsley. Sauté for about 30 seconds to combine the flavors.
  7. Create the Sauce: Pour in the full-fat coconut milk and reserved starchy pasta water. Stir continuously until the sauce is thick, rich, and glossy. Then turn off heat.
  8. Toss Pasta with Sauce: Add the cooked pasta noodles to the saucepan and mix thoroughly to coat evenly with the sauce. Taste and season with additional salt and at least ½ teaspoon ground black pepper as desired.
  9. Serve: Serve the pasta warm. Optional garnishes include fresh thyme or a sprinkle of vegan Parmesan cheese to enhance the dish’s flavor and presentation.

Notes

  • Be patient when caramelizing onions; low and slow heat yields the best sweetness and depth.
  • Adjust the amount of roasted garlic paste according to your taste preference for garlic intensity.
  • Reserve pasta water is important to help emulsify and thicken the sauce.
  • This dish is naturally vegan and vegetarian, and dairy-free.
  • For extra flavor, try adding fresh herbs like thyme or basil when serving.
  • Use full-fat coconut milk for a creamy texture; light coconut milk will produce a thinner sauce.
  • Pasta choice can be swapped but choose long noodles like spaghetti or linguine for best sauce coating.
