This velvety smooth and flavorful green pasta sauce packs in fresh baby spinach for an easy and delicious way to get your greens. The creaminess comes from blending cashews, resulting in a nutritious dairy-free pasta dish in under 30 minutes!

Weeknight pasta dishes are popular for good reason. They're quick, simple and comforting, you can easily adjust the recipe to make as much or as little as you need, and one pot can satisfy everyone in the family, including the kids.

I love varying up the sauces on pasta night so it never gets boring, whether it's a savory and sweet roasted veggie tomato sauce, a rich cashew-based cream sauce, a fresh and herby pesto sauce, or even a nutty tahini sauce. All have different flavors and textures that drastically change the flavor profile of a dish even if all other ingredients remain constant.

A new dish I am adding to my list of healthy vegan pasta recipes is this easy green sauce pasta! The combination of the creamy pasta sauce with the aromatics of sautéed shallots and garlic creates a savory yet light springtime recipe that works with any type of pasta.

It took me a few attempts to perfect this recipe. At first I tried puréeing the sautéed shallots and garlic directly into the sauce and serving it over the pasta. While it tasted good, I knew it could be so much better.

I then tested keeping the sautéed shallots and garlic separate from the sauce and it made a huge difference! Shallots get sweet when sautéed, which got a little lost when I puréed it into the sauce. Adding them to the pasta and then mixing with the creamy green sauce poured overtop created so much more flavor!

The entire recipe uses just a handful of ingredients. See the recipe card at the end of the post for exact quantities.

How to Make this Green Sauce Pasta

1. Prepare the green pasta sauce. Blend all sauce ingredients in a high-speed blender until it transforms into a creamy sauce. Set aside.

2. Begin cooking the pasta according to package instructions in a large pot of water.

3. Sauté the shallots. While the pasta cooks, heat a 12-inch skillet (or large pan) over medium heat. Add the olive oil, diced shallot, salt and red pepper flakes and sauté for about 5 minutes until the shallots are soft, fragrant and translucent.

4. Sauté the garlic. Turn the burner to low and add the minced garlic to the skillet. If using maple syrup, add at this time as well. Sauté for 1-2 minutes.

Recipe Tips

Save a cup of pasta water. Use the reserved pasta water to thin out the sauce if too thick. You can also use a little water to rehydrate the dish if reheating leftovers on the stovetop. Store in an airtight container in the refrigerator for 3-4 days.
Feel free to customize! For both the sauce and the pasta, using more or less of any particular ingredient is perfectly fine. Add more red pepper flakes for additional heat or remove it altogether to make it more kid-friendly... this recipe is flexible!
Boost the protein content. Use quinoa or chickpea pasta or sprinkle additional hemp seeds on top to add some extra protein.

Nutritional Benefits of the Green Pasta Sauce

The two primary ingredients in this healthy pasta sauce are cashews and fresh spinach, both of which offer many benefits as part of a balanced diet.

Cashews

As a staple for creamy plant-based dishes, cashews are loaded with nutrients. They are a good source of plant-based protein (5g protein per ounce) as well as copper, magnesium, manganese, zinc, phosphorus and vitamins B1 and K.

According to the National Library of Medicine, nut consumption has been found to decrease total and LDL-cholesterol in addition to contribute to a reduced risk of coronary heart disease (source).

Spinach

Spinach is a vitamin K powerhouse, which helps with blood clotting and bone health. It is also rich in vitamins A and C as well as iron (source). Getting enough iron is especially difficult for vegans and spinach is one of the best plant-based sources!

Spinach also has various antioxidants, helping to protect against diseases, as well as potassium which helps to lower blood pressure (source).

Kid-Friendly, Dye-Free Green Pasta

This beautiful green pasta is actually perfect for St. Patrick's Day while also sneaking leafy greens into your kids' diets. While I believe it is important to introduce kids to whole vegetables, this dish is super convenient if they are hesitant to eat spinach on their own.

Serve this entrée after sharing a St. Patrick's Day snack board to really get in the spirit of the holiday!
