Happy Wednesday! I have a new recipe today, and then I’m taking a break from cooking until this weekend.

This creamy spinach sauce is extra lush and creamy thanks to the combination of mascarpone and finely grated Parmigiano-Reggiano. With the help of a food processor or blender, it comes together quickly and tastes fantastic with broad pasta, like tagliatelle, pappardelle, or fettuccine.

Creamy Spinach Pasta Sauce

• 5 ounces spinach, rinsed thoroughly

• 3 tablespoons extra virgin olive oil, divided

• 1 yellow onion, peeled and diced

• 4 cloves garlic, peeled and roughly chopped

• ½ cup loosely packed fresh basil, plus a few leaves for garnish

• ½ cup loosely packed fresh parsley

• ¼ cup shelled pistachios, unsalted

• 1 lemon, juiced

• ½ cup marscarpone or ricotta cheese

• ¾ cup finely grated Parmigiano-Reggiano, divided

• 12 ounces tagliatelle

• 1 cup pasta cooking water

• Salt and pepper to taste

Instructions

Blanch the spinach:

• Bring a large pot of water to a boil. Once boiling, add the spinach and boil it for 30 seconds. Transfer to an ice bath and set aside.

Sauté the onions and garlic:

• Heat 1 tablespoon olive oil in a small pot over medium-low heat. Add the onion and cook, stirring occasionally, for 10–12 minutes until very soft.

• Add the roughly chopped garlic and cook for 1 minute. Season with a pinch of salt and turn off the heat. Set aside.

Cook the pasta:

• To the pot of boiling, salted water, add the pasta and cook until al dente. Scoop out 1 cup of the pasta cooking water and set aside.

Prepare the sauce:

• Drain the spinach and squeeze out as much of the excess water as possible.

• Place the basil, parsley, pistachios, spinach, and lemon juice in a food processor or blender. Pulse until finely minced. Add 2 tablespoons extra virgin olive oil and pulse again until incorporated.

• Add the mascarpone, cooked onions and garlic, and ½ cup of Parmigiano-Reggiano to the food processor along with a big pinch of salt. Pulse until smooth. Add half of the pasta water and continue blending until smooth. Transfer the sauce to a bowl.

Sauce the pasta:

• Add the cooked pasta to the bowl of sauce. Toss to coat, adding more pasta cooking water as needed until the pasta is completely coated.

To serve:

• Divide the pasta between shallow bowls. Garnish with the remaining grated parm and a few basil leaves. Finish each bowl with a drizzle of extra virgin olive oil if you like. Enjoy!

Notes:

You can leave the water boiling, add salt, and reuse it for the pasta. However, if you notice any grit in the water, I recommend dumping it, filling the pot back up with fresh water, and bringing it to a boil for the pasta.
