- Boil the Zucchini – Start with salted water at a full boil. Drop in your zucchini and let it cook till fork-tender about 5 minutes. You’ll use this same water for your pasta!
- Blend the Sauce – In a high-speed blender (like Vitamix or Nutribullet), combine spinach, basil, Boursin, garlic powder, salt, pepper, and lemon juice (optional). Add the cooked zucchini and 2/3 cup of that hot pasta water. Blend until it’s ultra-smooth and bright green.
- Cook the Pasta – Boil until al dente, then drain and return it to the pot.
- Mix & Serve – Pour the sauce over the hot pasta and stir gently to coat. Top with extra basil and cracked pepper.
The sauce will be creamy, herbaceous, and rich without any heavy cream!

Avoid These Mistakes
Common Mistakes & Fixes
Even with a simple recipe like this one, a few hiccups can make the difference between “meh” and magic. Here’s how to avoid them:
- Using a weak blender
🛠 Fix: A high-speed blender like Vitamix or Nutribullet is key for a smooth, velvety sauce. An immersion blender often leaves the texture gritty. - Not seasoning the pasta water
🛠 Fix: Add a generous pinch of salt to the water before boiling it’s your only chance to season the pasta itself. - Draining all the zucchini water
🛠 Fix: Reserve at least 2/3 cup of the boiling water. It loosens the sauce and adds body thanks to the starchy liquid. - Overcooking the spinach
🛠 Fix: Don’t cook the spinach at all just blend it raw. That’s how you get that vibrant green color and fresh flavor.
Pro Tips to Get It Right
- Cook pasta and veggies in the same pot
Save time (and dishes!) by using the same pot to cook the zucchini and pasta. Just remove the zucchini with a slotted spoon and reuse the water. - Double the sauce, freeze for later
This spinach Boursin sauce freezes beautifully. Store in ice cube trays or small bags for a quick lunch later.

Is this creamy spinach pasta good for meal prep?
Yes — it stores beautifully for up to 4 days in the fridge. For best results, reheat it with a splash of cream or broth to keep the sauce smooth.
Can I make the sauce ahead of time?
Definitely. You can make and freeze the sauce for up to 3 months. Just thaw overnight and re-blend with a splash of hot water to refresh it.
