Step 1

Place the Creamy Sauce ingredients in a blender and puree until smooth. Adjust salt to your taste.

Step 2

Heat oil in a large skillet over medium high heat. Add garlic and cook for 20 seconds, then add onion and cook for 3 to 5 minutes until translucent and cooked through.

Step 3

Meanwhile, cook your pasta of choice in a large pot of salted boiling water until al dente (just cooked through but still firm). SCOOP out 1 mug of the pasta cooking water, then drain the pasta.

Step 4

Add the pasta into the skillet, then pour the Creamy Sauce in, all the spinach and about 1/2 cup of the pasta water (Note 5). Stir to coat the pasta in the sauce and to wilt the spinach. Cook, stirring gently, for about 2 minutes until the sauce is warmed through. Adjust salt to taste.

Step 5

Use the remaining pasta water to get the sauce to the consistency you want.

Step 6

Remove from the stove and serve immediately, with more parmesan cheese and basil if desired.
