Vegan Creamy Avocado Lime Pasta

There's something almost magical about the moment when bright green avocado cream coats warm pasta—it happened to me on a Tuesday evening when I was determined to prove that vegan cooking could be just as indulgent as anything else. The kitchen filled with the scent of lime and basil before I'd even finished blending, and my skeptical roommate wandered in asking what smelled so good. Twenty minutes later, we were both twirling forks through silky sauce studded with sweet tomatoes, and I realized this wasn't just a quick weeknight dinner—it was the kind of dish that makes you feel like you're eating something special without any fuss.

I made this for a friend who'd recently gone vegan and kept apologizing about being difficult at dinner parties, like she'd become a burden somehow. Watching her face light up when she took that first bite—when she realized she could have something this creamy and satisfying—that was worth every bit of the effort, even though there barely was any.

Ingredients

• 350 g dried spaghetti or linguine: The thinner the pasta, the better it clings to that silky sauce; I've found linguine catches the avocado cream more elegantly than thicker shapes.
• 2 ripe avocados, peeled and pitted: This is everything—underripe and your sauce tastes thin, overripe and it browns before you finish blending, so aim for that perfect moment when they yield to gentle pressure.
• 1 large lime, juiced: Fresh lime is non-negotiable here; bottled juice tastes tinny and flat in comparison, and you need that brightness to balance the richness.
• 2 cloves garlic, peeled: Just two, because you want the garlic as a whisper, not a shout that overwhelms the delicate avocado.
• 3 tbsp extra virgin olive oil: Good quality matters because this sauce is mostly fat and aromatics; cheap oil makes it taste cheap.
• 1/3 cup fresh basil leaves: Tear them in by hand rather than cutting, which bruises them and turns the leaves dark and bitter.
• 1/4 cup unsweetened plant-based milk: Oat milk makes the creamiest sauce, though almond works too—soy can sometimes add a weird aftertaste I'm not fond of.
• 1/2 tsp sea salt and 1/4 tsp freshly ground black pepper: Season in layers as you taste, because the pasta water you add at the end can dilute things.
• Pinch of chili flakes: Optional, but they add a subtle warmth that makes people wonder what the secret ingredient is.
• 250 g cherry tomatoes, halved: The sweetness of good tomatoes is what makes this dish feel complete; mealy ones will disappoint.
• 2 tbsp toasted pine nuts: Worth the extra expense for their buttery crunch, though sunflower seeds work in a pinch.
• Fresh basil for garnish: A handful more than you think you need, scattered over the top just before eating.

Instructions

Get your water boiling and pasta cooking:

Salt your water until it tastes like the sea—this is your only chance to season the pasta itself. Drop in your spaghetti and stir immediately so nothing sticks together, then set a timer and actually pay attention to when it's done.

Make the sauce while pasta finishes:

Throw avocados, lime juice, garlic, olive oil, basil, milk, salt, pepper, and chili flakes into your blender or food processor. Blend until it's completely smooth and looks almost impossibly green and creamy, then taste it and adjust—more salt, more lime, whatever it needs.

Combine pasta and sauce:

Drain your pasta but save that water like it's liquid gold. Toss the hot pasta with the avocado sauce right away, when the pasta is still warm enough to help the sauce coat every strand.

Loosen if needed:

If your sauce feels too thick or clingy, splash in a bit of that reserved pasta water and toss again until it flows like silk. The pasta will continue absorbing liquid as it sits, so err on the side of saucier.

Fold in the tomatoes:

Gently toss in your halved cherry tomatoes so they stay intact rather than getting mangled. You want them to pop sweetly between your teeth, not dissolve into mush.

Serve with all the garnishes:

Divide into bowls while everything is still warm, scatter pine nuts and fresh basil over the top, and serve immediately because this dish waits for no one.

Pin It

There was a moment last summer when I brought this to a picnic potluck, and I watched people who eat meat most nights come back for seconds. No one asked if it was vegan until they'd already finished, and that's when I knew I'd made something that transcends dietary categories—it's just delicious, full stop.

The Secret to Avocado Sauce

I used to think avocado-based sauces were fragile things that turned brown and separated if you looked at them wrong, but I've learned they're actually quite forgiving if you understand what's happening. The acid from the lime juice prevents oxidation, so as long as you're generous with citrus, your sauce stays bright green and silky. The key is balance—enough fat to feel luxurious, enough acid to taste fresh, enough liquid to coat the pasta without turning into soup.

Making It Your Own

This recipe is a wonderful base, but it invites playing around. I've added white beans for protein when I'm cooking for myself, swapped the basil for cilantro when I'm feeling adventurous, and once tossed in some roasted red peppers because I had them hanging around. The structure stays solid no matter what you add, which is the mark of a truly good recipe.

Timing and Planning

The beauty of this dish is that it genuinely takes twenty minutes from cold kitchen to hot bowl—no advance prep, no complicated mise en place. I often make it on nights when I'm tired because it feels fancy enough to be satisfying but simple enough that I'm not standing at the stove for long. The main thing is making sure your avocados are ripe and your lime is fresh before you start.

• Buy avocados a day or two before you plan to make this so they're perfectly ripe when you need them.
• If you're making this for guests, have the sauce blended and ready to toss right when the pasta drains—timing is everything for keeping the pasta warm and the sauce silky.
• Don't skip the pine nuts if you can help it, because their buttery crunch is what takes this from good to memorable.

This pasta has become my go-to answer when someone asks what to cook on nights when you want something that feels indulgent but doesn't tie you to the kitchen. It's proof that simple ingredients, treated with care, are all you need.
