Step‑by‑Step Instructions for creamy spinach pasta sauce
Step 1: Blanch the Spinach
Bring a large pot of water to a rolling boil over high heat. Carefully add the fresh spinach and blanch for just 30 seconds, ensuring it softens and brightens. Immediately transfer the spinach to an ice bath using a slotted spoon to halt the cooking process, preserving its vibrant green color. Once cooled, drain and gently squeeze out any excess water.
Step 2: Sauté the Aromatics
In a small pot, heat 1 tablespoon of extra virgin olive oil over medium heat. Add the diced yellow onion and sauté for 10-12 minutes, stirring frequently until the onion is soft and translucent. Add the roughly chopped garlic and sauté for another minute, just until fragrant. Remove from heat and set aside, allowing these sweet aromatics to cool slightly.
Step 3: Cook the Pasta
In the same pot used for blanching the spinach, bring water to a boil again and add a generous pinch of salt. Cook the tagliatelle according to package instructions until al dente, usually about 8-10 minutes. Reserve 1 cup of the pasta cooking water before draining the pasta to maintain the necessary liquid for the creamy spinach pasta sauce.
Step 4: Prepare the Sauce
Using a blender, combine the drained spinach with the fresh basil, parsley, shelled pistachios, lemon juice, and the remaining 2 tablespoons of olive oil. Blend until finely minced. Next, add the mascarpone, the sautéed onion and garlic mixture, and half of the finely grated Parmigiano-Reggiano cheese. Blend until the mixture is smooth, gradually adding reserved pasta water to achieve your desired creamy texture.
Step 5: Combine Pasta and Sauce
In a large serving bowl, toss the drained, cooked tagliatelle with the creamy spinach pasta sauce. Mix gently to coat the pasta evenly, using additional reserved pasta water as needed to help the sauce cling to the noodles while maintaining a luxurious consistency.
Step 6: Serve and Garnish
Divide the creamy spinach pasta into individual bowls, garnishing each with a sprinkle of the remaining Parmigiano-Reggiano cheese and a drizzle of extra virgin olive oil for added richness and flavor. Serve your delightful meal warm, inviting everyone to enjoy this comforting and vibrant dish!

Expert Tips for Creamy Spinach Pasta Sauce
• Blanch with Care: Ensure the spinach is blanched for just 30 seconds to retain its vibrant color and nutrients.
• Pasta Water Magic: Gradually add reserved pasta water while mixing the sauce for the perfect creamy consistency; too much at once can thin it out.
• Taste as You Go: Always taste and adjust seasoning of your creamy spinach pasta sauce according to your preferences. A pinch more salt or lemon juice can elevate flavors significantly.
• Nutty Alternatives: For a twist, feel free to swap pistachios for walnuts or pecans; each nut adds its own unique flavor and texture to the sauce.
• Make-Ahead Option: Consider preparing the creamy spinach pasta sauce a day in advance for enhanced flavors; simply reheat gently when ready to serve.
