If you’ve been looking for a pasta recipe that checks every box quick, filling, genuinely delicious, and high in protein this cheesy green sauce pasta is going to become a regular in your kitchen.
It’s plant based, comes together in under 30 minutes, and the sauce is so creamy and flavorful that people who aren’t even trying to eat more plants will ask for the recipe.
The green color might make you hesitate for a second. Don’t let it. This sauce tastes rich, cheesy, and satisfying in a way that doesn’t feel like a compromise at all.
Why This Pasta Actually Delivers on Protein
Most pasta dishes are carb heavy and light on protein unless you add meat or eggs. This recipe takes a smarter approach.
The sauce itself contains cashews, nutritional yeast, tahini, and frozen peas all meaningful sources of plant based protein. Then when you cook the pasta, choosing a bean-based pasta instead of regular wheat pasta adds another significant protein boost.
Bean pasta made from chickpeas, black beans, lentils, or edamame is widely available at grocery stores like Whole Foods, Trader Joe’s, Target, and most mainstream supermarkets.
Brands like Banza (chickpea pasta) are popular and easy to find. Compared to regular pasta, bean pasta typically contains two to three times the protein per serving and more fiber. It cooks similarly to regular pasta and takes on sauces just as well.
On top of all that, the dish gets finished with hemp seeds. Hemp seeds are one of the most protein dense toppings you can add to any meal about 10 grams of protein per three tablespoons and they add a subtle nutty flavor without being overpowering. You’ll find them at Whole Foods, Sprouts, Costco, and most health food sections.
Breaking Down the Cheesy Green Sauce
This sauce is built on a few ingredients that each pull real weight:
Spinach and frozen peas form the green base. They get cooked briefly in a pan first just enough to wilt the spinach and defrost the peas before going into the blender. This step keeps the color bright and the flavor fresh rather than muddy.
Cashews, soaked in hot water for 10 minutes and drained, are what make the sauce genuinely creamy When blended, soaked cashews become incredibly smooth and add a buttery body that mimics a dairy based cream sauce. This is a technique worth knowing for many plant-based recipes.
Nutritional yeast is the ingredient that gives the sauce its cheesy flavor. It’s a deactivated yeast sold as yellow flakes or powder, and it has a naturally savory, slightly nutty, cheese like taste.
If you haven’t cooked with it before, you’ll find it at Whole Foods, Sprouts, Amazon, and many mainstream grocery stores near the health food or bulk sections. It’s not the same as active dry yeast used in baking make sure you pick up nutritional yeast specifically.
Oat milk keeps the sauce pourable and blendable. Any unsweetened plain oat milk works here. You can also substitute unsweetened almond milk or soy milk if that’s what you have on hand.
Tahini adds depth and nuttiness. Lemon juice adds brightness. A clove of garlic and a pinch of smoked paprika add savory warmth. Together these ingredients build a sauce that tastes far more complex than the ingredient list suggests.
How to Make It
Start by heating a skillet over medium heat. Add the frozen peas and cook for a few minutes until they’re fully defrosted. Add the two large handfuls of spinach and stir until wilted. Remove from heat.
Transfer the cooked peas and spinach into a blender. Add the soaked and drained cashews, oat milk, nutritional yeast, tahini, lemon juice, garlic clove, smoked paprika, and a pinch of salt and pepper.
Blend everything until completely smooth. The sauce should be thick but still pourable. If it’s too thick, add a little more oat milk and blend again until you reach the right consistency.
Cook your pasta of choice according to the package instructions. Bean pasta is the go to recommendation here for the protein boost, but any pasta shape works. Drain the cooked pasta and immediately stir in the green sauce while the pasta is still hot. The heat helps the sauce coat every piece of pasta evenly.
Serve in bowls and top with red chili flakes, hemp seeds, and fresh chopped parsley. That’s it.
The whole recipe serves four to five people and stores well in the fridge for four to five days, making it a solid meal prep option for the week.
Serving Ideas
This pasta works equally well as a weeknight dinner and as a meal prep staple. Pack it into containers for lunch throughout the week it reheats well with a splash of water or oat milk stirred in to loosen the sauce.
For a more filling dinner, serve it alongside a simple green salad or roasted vegetables. Roasted cherry tomatoes on top add a nice burst of acidity that pairs well with the richness of the green sauce.
No. Any pasta works in this recipe. Regular spaghetti, penne, rotini whatever you have. Bean pasta is the recommendation specifically if you want to increase the protein content of the dish significantly. Chickpea pasta from brands like Banza is the most widely available option in the US.
Nutritional yeast is the key to the cheesy flavor in this sauce. It’s worth sourcing Whole Foods, Sprouts, Amazon, and many Target locations carry it. There isn’t a direct substitute that replicates the same flavor, but a small amount of white miso paste adds a similar savory depth if you’re in a pinch.
Yes. Unsweetened almond milk or unsweetened soy milk both work. Make sure whichever milk you use is plain and unsweetened flavored or sweetened varieties will throw off the flavor of the sauce.
Soaking for 10 minutes in hot water is important if you want a truly smooth sauce. Unsoaked cashews can leave the sauce slightly grainy depending on your blender. If you have a high-powered blender like a Vitamix, you can get away with skipping the soak, but the 10-minute soak is quick and worth doing.
Hemp seeds are the shelled seeds of the hemp plant. They have a mild, slightly nutty flavor and are exceptionally high in protein and healthy fats. Find them at Whole Foods, Sprouts, Costco, Trader Joe’s, and most health food sections of major supermarkets. They’re often labeled as “hemp hearts.”
It can be. The sauce itself is naturally gluten free. To keep the full dish gluten-free, use a certified gluten-free pasta many bean pastas are already gluten-free, but always check the label.
The finished pasta stores in the fridge for four to five days in an airtight container. When reheating, add a small splash of water or oat milk and stir well to bring the sauce back to its original creamy consistency.
