Creamy Avocado Spinach Pasta

There's something about green sauce that stops me mid-conversation. I was standing in my kitchen on an ordinary Tuesday, staring at two perfectly ripe avocados and a handful of spinach, when it hit me: what if I stopped fighting the urge to blend them together and just leaned in? Twenty minutes later, I had a bowl of silky pasta that tasted like I'd been cooking it for hours, even though I hadn't. My roommate came home to the smell of garlic and lemon and immediately asked when dinner would be ready, not realizing it already was.

I made this for my sister who'd been talking about eating healthier, and I watched her twirl her fork through that vivid green pasta with an expression that said she couldn't believe something this indulgent was actually good for her. She asked for the recipe before she'd even finished, which tells you everything about how this dish lands.

Ingredients

• Spaghetti, 400g: Use whatever shape you love, but spaghetti's long strands are perfect for catching every drop of that creamy sauce.
• Ripe avocados, 2: They should yield slightly to pressure but not feel mushy; this is where the sauce gets its silky texture and rich flavor.
• Fresh baby spinach, 100g: The mild, delicate kind blends seamlessly and adds brightness without any bitter aftertaste.
• Garlic, 2 cloves: Fresh and peeled, these two cloves add a whisper of pungency that ties everything together.
• Extra-virgin olive oil, 60ml: This is your emulsifier in disguise; it makes the sauce come together as one gorgeous thing.
• Fresh lemon juice, 30ml: Prevents the avocado from browning and adds a vital spark of acidity that makes you want another bite.
• Parmesan cheese, 30g: Grated fresh, it adds umami depth and a subtle salt that seasons the whole dish.
• Fresh basil leaves, 2 tbsp: Optional, but if you have it, it adds an herbal note that feels like the dish is a complete thought.
• Sea salt and black pepper: Season generously; this sauce needs enough salt to wake up all the quiet flavors.
• Pasta cooking water, 2-4 tbsp: This starchy liquid is the secret to making everything creamy and luxurious without cream.

Instructions

Get your water boiling:

Fill a large pot with water, add a generous handful of salt (it should taste like the sea), and let it come to a rolling boil while you prep everything else. This takes about 10 minutes, and the salt is non-negotiable; it's your only chance to season the pasta itself.

Cook the pasta:

Add your spaghetti and stir it once or twice so nothing sticks. Cook until al dente, which means it still has a tiny bit of resistance when you bite it, then reserve about 1/2 cup of that starchy cooking water before draining. This water is liquid gold for the sauce.

Build your sauce while pasta cooks:

Put your avocados, spinach, garlic, olive oil, lemon juice, Parmesan, basil if you're using it, salt, and pepper into a food processor or blender. Pulse it a few times, then blend until absolutely smooth, scraping down the sides as needed so nothing hides in the corners.

Make it pourable:

Add 2 to 4 tablespoons of your reserved pasta water and blend again until the sauce looks creamy and pourable, like it's ready to coat every strand. This step changes everything; without this water, the sauce sits thick and heavy.

Bring it together:

Return your warm, drained spaghetti to the pot and pour the avocado sauce over it, then toss everything with real intention so every strand gets coated. Add a splash more pasta water if it looks too thick; you want it to flow like it's alive.

Plate and finish:

Divide the pasta among bowls, then finish each one with a sprinkle of lemon zest, a shower of extra Parmesan, and a generous crack of black pepper. Serve right away while the pasta is still warm and the sauce is at its best.

The first time someone told me pasta could be this virtuous, I didn't believe them. But standing there with a warm bowl in my hands, tasting something that felt indulgent and nourishing at the same time, something shifted. This dish stopped being just dinner and became proof that good food doesn't require apology or lengthy ingredient lists.

Why Avocado Is Your Secret Weapon

Avocado gets talked about too much and understood too little. Yes, it's creamy, but what people miss is that it's a blank canvas that takes on the personality of everything you blend it with. Here, the lemon makes it bright, the garlic makes it savory, and the spinach makes it feel less decadent than it actually is. It's a vegetable masquerading as cream, and that's where the magic lives.

Variations That Keep Things Interesting

This sauce is forgiving enough to adapt to whatever you've got in your kitchen. I've stirred in roasted cherry tomatoes for sweetness, added sautéed mushrooms for earthiness, and tossed in toasted walnuts for crunch when I wanted texture. For vegan nights, nutritional yeast steps in beautifully for the Parmesan, giving you that savory depth without the dairy. The sauce doesn't care about your dietary choices; it's flexible enough to work with all of them.

The Quick Kitchen Wisdom

This recipe lives in that sweet spot where speed doesn't mean sacrifice. The most important lesson I've learned is that the best meals aren't always the ones that take the longest; they're the ones where every ingredient is there for a reason.

• Have your avocados ready to go; unripe ones will ruin your entire plan, so choose with care.
• Taste the sauce before you toss it with pasta; you might want more lemon or salt than you think.
• If you're feeding a crowd, this doubles easily without losing any of its elegance.
