For the Pasta

• 200g (7 oz) whole wheat or gluten-free pasta (spaghetti, fettuccine, or penne)
• 1 tsp salt (for pasta water)
• 1 tsp olive oil (optional, to prevent sticking)

For the Creamy Spinach Sauce

• 1 cup (30g) fresh spinach leaves, packed
• ¼ cup (30g) raw cashews, soaked in hot water for 5 minutes
• ½ cup (120ml) unsweetened plant-based milk (cashew, almond, or oat)
• 2 tbsp nutritional yeast (for cheesy flavor and B vitamins)
• 1 tbsp lemon juice (brightens flavor and aids nutrient absorption)
• 1 small garlic clove, minced
• ½ tsp salt (or to taste)
• ¼ tsp black pepper
• ¼ tsp onion powder
• 1 tbsp olive oil (for sautéing garlic)

Step-by-Step Instructions for Perfect Creamy Vegan Spinach Sauce Pasta

Step 1: Cook the Pasta

1. Bring a large pot of water to a rolling boil. Add 1 tsp salt and the pasta of your choice.
2. Cook according to package instructions until al dente (usually 8–10 minutes).
3. Before draining, carefully reserve ½ cup of the pasta water. Drain the pasta and set aside.

Step 2: Prepare the Sauce Base

1. Drain and rinse the soaked cashews thoroughly to remove any bitter taste.
2. In a high-speed blender, combine the spinach, cashews, plant-based milk, nutritional yeast, lemon juice, minced garlic, salt, pepper, and onion powder.
3. Blend on high until completely smooth, scraping down the sides as needed. If the mixture is too thick, add 1–2 tbsp of the reserved pasta water to help it blend smoothly.

Step 3: Sauté the Aromatics (Optional but Recommended)

1. In a large skillet, heat the olive oil over medium-low heat.
2. Add the minced garlic and sauté for just 30 seconds, stirring constantly, until fragrant. Be careful not to let it brown.
3. Pour the blended spinach sauce into the pan and warm through for 1–2 minutes, stirring occasionally.

Step 4: Combine and Serve Your Creamy Vegan Spinach Sauce Pasta

1. Add the cooked pasta to the skillet with the sauce. Toss gently to coat every strand or piece evenly.
2. If needed, add reserved pasta water 1 tbsp at a time until you reach your desired level of creaminess.
3. Serve immediately, garnished with extra spinach leaves, a sprinkle of nutritional yeast, or a pinch of red pepper flakes for a little heat.

Tips & Tricks for the Creamiest Vegan Spinach Sauce Pasta

• Soak cashews properly: For the smoothest texture, soak cashews in hot water for at least 5 minutes. If you forget, soak them in cold water for 30 minutes instead.
• Adjust thickness easily: The sauce thickens as it cools. If it becomes too thick after refrigeration, simply stir in a splash of plant milk or water when reheating.
• Boost the flavor: Add a pinch of smoked paprika or turmeric for depth, or stir in a spoonful of miso paste for umami richness.
• Make it nut-free: Swap cashews for ¼ cup sunflower seeds or silken tofu for a nut-free version that’s just as creamy.

How to Store and Freeze Your Creamy Vegan Spinach Sauce Pasta

Refrigerator Storage

• Sauce only: Store the sauce in an airtight container in the fridge for up to 3 days. When ready to use, reheat gently in a saucepan with a splash of water or plant milk to restore creaminess.
• Pasta + sauce: While best eaten fresh, you can refrigerate the combined dish for up to 1 day. Note that the pasta may soften slightly upon reheating.

Freezer Instructions

• Freeze the sauce: Portion the sauce into freezer-safe containers or ice cube trays. Freeze for up to 3 months. Thaw overnight in the refrigerator before reheating.
• Reheat from frozen: Warm the thawed sauce in a saucepan over low heat, stirring occasionally. Add a little water or milk if needed to thin it out.

Variations: 3 Delicious Ways to Customize Your Vegan Spinach Sauce Pasta

• Protein-packed version: Stir in ½ cup of cooked lentils, chickpeas, or white beans for extra plant-based protein and fiber. This makes the dish more filling and balanced.
• Extra veggie boost: Sauté ½ cup of sliced mushrooms, cherry tomatoes, or bell peppers with the garlic for added texture and nutrients. This works especially well with penne or fusilli.
• Creamy avocado twist: Blend in ¼ of a ripe avocado for a richer, buttery texture and healthy fats. This variation is perfect for those who love extra creaminess.

Serving Suggestions: 3 Ways to Enjoy Your Creamy Vegan Spinach Sauce Pasta

• Classic bowl: Serve the pasta as is, topped with a sprinkle of nutritional yeast and fresh spinach leaves. This is the simplest and most satisfying way to enjoy it.
• Baked pasta bake: Transfer the sauce and pasta to a baking dish, top with breadcrumbs or vegan cheese, and bake at 375°F (190°C) for 10–15 minutes until golden and bubbly.
• Meal prep bowl: Pack the pasta and sauce separately in meal prep containers. Serve cold or at room temperature with a side of garlic bread or a simple salad for a complete lunch.

Frequently Asked Questions

Can I use frozen spinach instead of fresh?

Absolutely! Frozen spinach works just as well. Thaw it completely and squeeze out all excess water before blending to prevent a watery sauce.

Is this recipe nut-free?

This recipe contains cashews, but you can easily make it nut-free. Substitute the cashews with ¼ cup of sunflower seeds or silken tofu for a similarly creamy texture.

Can I make this recipe oil-free?

Yes! Skip the olive oil entirely. Sauté the garlic in a splash of water or vegetable broth instead to prevent sticking and add flavor.

Why do you soak the cashews?

Soaking cashews softens them, making them easier to blend into a smooth, creamy sauce. It also removes any bitterness and ensures a velvety texture without graininess.

How long does this pasta keep in the fridge?

The sauce alone keeps well for up to 3 days in the fridge. If combined with pasta, it’s best eaten within 1 day, as the pasta may become softer upon reheating.
