This flavorful spinach and basil pasta is tossed with lemon juice, zest, parmesan, pistachio, creamy burrata cheese, and chili flakes.
Add the spinach, basil, parmesan, garlic, lemon juice, lemon zest, salt, and ¼ cup of the olive oil to a blender or food processor. Blend at low speed until chopped, then increase speed to medium low and add the remaining 1/4 cup olive oil in a thin stream through the small hole in the top of the blender or food processor. Blend until relatively smooth with finely chopped bits of greens, stopping the blending to scrape down the inside with a rubber spatula, if needed. Makes about 1 cup of sauce.
Add the spinach + basil sauce to the small saucepan with the pasta water and whisk to combine. Over medium-low heat, heat it up until hot but not boiling, whisking every couple minutes. Remove from heat and set aside.
Drain the cooked bucatini and place back in the big pot. Pour the spinach + basil sauce over it, add the chopped burrata (will be wonderfully goopy so scrape all the creamy goo off the cutting board and into the pot), pistachio, and red pepper flakes and toss with two wooden spoons to coat the noodles in the sauce. Enjoy immediately!
