Step‑by‑Step Instructions for creamy spinach pasta sauce
Step 1: Blanch Spinach
Bring a large pot of water to a rolling boil over high heat. Add fresh spinach and blanch for 30 seconds until vibrant green; immediately transfer to an ice bath to halt cooking and preserve nutrients. Drain well, squeezing out excess water to ensure your creamy spinach pasta sauce won’t be watery.
Step 2: Sauté Onions and Garlic
In a medium skillet, heat 2 tablespoons of extra virgin olive oil over medium heat. Add diced yellow onion and sauté for 10 to 12 minutes until soft and translucent. Stir in minced garlic and cook for an additional 1 minute until fragrant, then remove from heat and let it cool slightly while preparing the sauce.
Step 3: Cook Pasta
In a large pot, bring salted water to a boil and add tagliatelle. Cook until al dente, typically around 8 to 10 minutes, then reserve 1 cup of pasta cooking water before draining the pasta. The perfect texture will ensure the creamy spinach pasta sauce clings beautifully to each fettuccine strand.
Step 4: Prepare Sauce
In a blender, combine the blanched spinach, fresh basil, parsley, pistachios, and lemon juice with 2 tablespoons of olive oil. Blend until finely minced, then add the sautéed onions, garlic, and mascarpone cheese. Blend again until smooth, incorporating half the grated Parmigiano-Reggiano for depth of flavor.
Step 5: Sauce Pasta
In the large pot used for pasta, return cooked tagliatelle to the pan and pour in the creamy spinach pasta sauce. Toss gently, adding sufficient reserved pasta water to achieve your desired sauce consistency. The sauce should effortlessly coat the pasta, creating a luscious, flavorful dish.
Step 6: Serve
Divide your creamy spinach pasta into serving bowls, garnishing with remaining grated Parmigiano-Reggiano and fresh basil leaves. For an extra touch, drizzle a bit of olive oil on top. Your beautiful pasta dish is ready to be enjoyed, promising comforting warmth and exquisite flavors!
