A perfect weeknight meal, 7 simple ingredients become an irresistibly creamy lemon pasta dish in minutes. With garlic and fresh lemon, pair it with your favorite steamed veggie for healthy vegan comfort food everyone will love! Vegan and gluten-free with an oil-free option.
If you enjoy the creaminess of mac and cheese and the fresh zing of lemon, you're going to LOVE this pasta! It's simple enough to throw together on a weeknight yet special enough for a dinner party.
Dress it up with fresh herbs and a sprinkle of Vegan Parm (OR see the grated cashew trick below). And for additional fiber and protein, cannelini or garbanzo beans would be perfectly at home stirred into this velvety sauce.
Round out the meal with a side salad or some lightly steamed broccoli or asparagus, and you're all set!
How to Make Creamy Vegan Lemon Pasta
Here's a quick run down of the process:
- Cook your pasta of choice. I used Trader Joe's gluten-free fusilli, but any pasta you like will work just fine. And as far as shapes go, try spaghetti, penne, bowtie, angel hair, fettuccini, or shells. Drain in a colander and set aside.
- Sauté 6 to 8 cloves of minced garlic for 1 to 2 minutes, just enough to deepen and soften the flavor. You can do this in a tablespoon of olive oil or vegan butter, or if you follow an oil-free diet use a splash of water or vegetable broth.
- Blend the sauce. Combine the garlic, zest of one lemon, water, raw cashews, arrowroot starch, and salt in a high speed blender.
*If you don't have a high speed blender, you can sub ½ cup raw cashew butter for the whole nuts. Or you can soak the raw cashews in hot water for about 30 minutes first, and use a regular blender.
- Pour the sauce into the pasta pot. Whisking constantly, cook over medium heat until thickened, just a few minutes. Whisk in ¼ cup fresh lemon juice.
- Add the cooked and drained pasta to the pot, stir to combine, and serve! Garnish with vegan parmesan cheese and fresh herbs, if desired.
About Arrowroot Starch
In the photo above you can see how deliciously creamy the sauce gets as you heat it. It looks almost like a country-style white gravy! But you won't find any butter or all-purpose flour here.
I really love arrowroot starch for creamy sauces like this. It takes on such a silky texture, making it ideal for this type of vegan sauce.
You can find arrowroot in most well-stocked grocery stores these days or online from sites like Amazon. It's great for thickening soups (vegan cream of mushroom, anyone?) and gravies.
According to Bob's Red Mill, you can also use arrowroot in homemade ice cream to help prevent the formation of ice crystals. I haven't tried this trick yet but am certainly intrigued!
See how the creamy lemon sauce clings to the corkscrew edges of fusilli? Just scrumptious.
Similar to what I love about my Best Vegan Stovetop Mac and Cheese, this sauce stays very creamy even as it cools. Some vegan cream sauces get dry, even sort of pasty- and clumpy-looking, as they cool. But arrowroot works wonders in this one.
Just make sure not to overcook the sauce. If heated for prolonged periods, arrowroot can lose its thickening abilities. Other than that, it's very easy to work with. Another perk is that it can withstand acidic ingredients like lemon juice, whereas corn starch doesn't always thicken well in the presence of acids.
Grated Cashews as a Sub for Parmesan
One last fun little tidbit!
While you have your microplane zester out for zesting the lemon, go ahead and grate a few cashews. Can you believe how much that looks like grated cheese? Since the nuts are small, just be careful not to zest your fingers!
You'll be amazed how much you get from just 2 or 3 nuts. After you grate the cashews, mix in a pinch of sea salt, maybe even a pinch of nutritional yeast, and then sprinkle this on the plates before serving.
