Ingredients You’ll Need
This recipe shines because it uses straightforward, kitchen-staple ingredients that come together to create complex flavors and luscious textures. Each component has an essential role, whether it’s building the sauce’s creaminess, infusing sweetness, or adding that perfect touch of seasoning.
- 1 head garlic: Roasting garlic softens its sharpness and brings out a sweet, mellow taste, forming the base of the sauce’s rich flavor.
- 1 teaspoon olive oil: Used to roast the garlic, adding a gentle fruity note and helping it caramelize beautifully.
- Sprinkle of salt & pepper: Balances and enhances the flavors from the outset.
- 8 ounces dried spaghetti or linguine: The classic canvas for this sauce, offering that satisfying al dente bite.
- 2 tablespoons vegan butter: Adds creamy richness and helps caramelize the onions to perfection.
- 1 tablespoon olive oil: Keeps the sauce smooth and silky while cooking the onions gently.
- 1 large yellow onion, thinly sliced: When slowly cooked, these onions transform into sweet, golden ribbons essential to the sauce’s depth.
- ½ teaspoon salt: Draws out moisture from the onions to speed up caramelization and intensify flavor.
- 2-3 teaspoons water: Helps deglaze the pan, preventing onions from burning and building layers of flavor.
- 1 ½ tablespoons vegan Worcestershire sauce: Adds a subtle umami punch that enriches the sauce’s savory character.
- 1 tablespoon roasted garlic paste: Made from the roasted garlic—you can adjust this amount to match your garlic love level.
- 1 teaspoon dried parsley: Brings a hint of herbaceous brightness to balance the richness.
- ½ cup full-fat coconut milk: Creates the luxuriously creamy texture without dairy, carrying all flavors perfectly.
- ¼ cup starchy pasta water: Reserved from cooking the pasta, it’s the secret to binding the sauce to the noodles flawlessly.
- Salt & pepper to taste: Essential final adjustments to make every bite sing, especially with at least ½ teaspoon freshly ground black pepper.
How to Make Vegan Caramelized Onion & Roasted Garlic Pasta Recipe
Step 1: Roast the Garlic
Start by heating your oven to 400°F. Prep the garlic bulb by peeling away the loose outer layers but keeping the bulb intact so the cloves roast evenly. Slice about a quarter inch from the top to expose the cloves inside, then place it on foil, drizzle with olive oil, and sprinkle with salt and pepper. Wrap it tightly in the foil, then roast for 30 to 40 minutes until the cloves are golden, soft, and fragrant. Once it’s cool enough to handle, squeeze out the cloves and mash them into a thick paste. This roasted garlic paste brings mellow sweetness and richness that becomes the sauce’s heart.
Step 2: Cook the Pasta & Caramelize the Onions
While your garlic roasts, cook the pasta according to package directions. Remember to reserve a quarter cup of the starchy pasta water before draining—that water is pure gold for your sauce! Meanwhile, thinly slice your onions. In a saucepan, melt vegan butter with olive oil over medium heat. Toss in the sliced onions and half a teaspoon of salt to coax out sweetness. Cook slowly, stirring every few minutes to avoid burning. This process takes about 30 to 40 minutes, but it’s worth the wait as your onions transform into sweet, soft, golden perfection. If the pan gets too dry or the onions start to brown too quickly, splash in a teaspoon or two of water to keep everything luscious and caramelizing smoothly.
Step 3: Combine and Finish the Sauce
Once your onions have caramelized, stir in the vegan Worcestershire sauce, the roasted garlic paste, and dried parsley. Saute this fragrant mixture for another 30 seconds to marry the flavors. Then pour in the coconut milk and reserved pasta water, stirring to create a thick, creamy sauce that clings to every strand of pasta. Turn off the heat, add the drained pasta, and toss until everything is coated in a glossy, indulgent sauce. Don’t forget to taste and season with salt and plenty of freshly cracked black pepper to bring out all the layers of flavor.
How to Serve Vegan Caramelized Onion & Roasted Garlic Pasta Recipe
Garnishes
A sprinkle of fresh thyme or some grated vegan Parmesan cheese on top lifts this dish to an even more elegant level. These simple touches add freshness and a bit of herbaceous or cheesy note that complements the rich sauce beautifully.
Side Dishes
Pair this pasta with a crisp green salad or garlic-roasted vegetables for a balanced meal. Something bright and fresh cuts through the creamy sauce perfectly, making every mouthful satisfying without feeling too heavy.
Creative Ways to Present
For a dinner party, serve this pasta in shallow bowls and drizzle a little extra virgin olive oil or sprinkle toasted pine nuts on top to add texture. A side of crusty bread also makes for an irresistible pairing, perfect for sopping up every last bit of that luscious sauce.
Make Ahead and Storage
Storing Leftovers
This Vegan Caramelized Onion & Roasted Garlic Pasta Recipe keeps beautifully in the refrigerator for up to 3 days. Store in an airtight container to preserve freshness and flavor. Before eating, give it a quick stir to redistribute the sauce.
Freezing
You can freeze leftovers, but for best texture, it’s preferable to store the caramelized onion sauce separately. Freeze it in portioned containers and thaw in the fridge overnight when ready to enjoy. The pasta itself is better fresh or refrigerated.
Reheating
Reheat gently on the stovetop over low heat, adding a splash of water or coconut milk if the sauce has thickened too much. This helps restore the creamy texture without drying out the pasta. Microwave reheating works too but be sure to stir halfway through for even warmth.
FAQs
Can I use a different type of pasta?
Absolutely! While spaghetti or linguine are ideal for this sauce, you can swap in penne, fusilli, or even gluten-free pasta to suit your preference or dietary needs. Just adjust cooking times accordingly.
Is this recipe nut-free?
Yes, this Vegan Caramelized Onion & Roasted Garlic Pasta Recipe contains no nuts, making it a great option for those with nut allergies.
Can I make the sauce without coconut milk?
You can substitute coconut milk with other plant-based milks like cashew or oat milk for creaminess, though coconut milk gives the richest texture and slightly sweet undertone.
How do I know when the onions are properly caramelized?
They should be deep golden brown, very soft, and smell sweet with no burnt bits. Slow cooking over medium to low heat is key to achieve this perfect texture and flavor.
Can I adjust the garlic intensity?
Yes! The roasted garlic paste amount is flexible. Add more for a stronger garlic punch or less if you prefer a subtler flavor. Roasting mellows raw garlic’s sharpness, so it’s hard to overdo it in this recipe.

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
- 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.
- 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.
- 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.
- Slice Onions: Thinly slice the yellow onion (or onions) while the pasta cooks.
- 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.
- 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.
- 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.
- 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.
- 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.
