I had Walnut Sauce for the first time last month in Italy when my husband and I were vacationing in Cinque Terre.  It was served with Pansotti, which is a stuffed pasta similar to ravioli, filled with ricotta and spinach.

My recipe deconstructs the dish a bit and simplifies the recipe putting those wonderful ricotta and spinach ingredients directly into the sauce and mixing it with a simple Fettuccine.

Walnuts are not just for sweet desserts!  When you blend nuts, it releases the oils and in combination with a little milk and other savory ingredients, they blend together to form a deliciously creamy texture and taste.  While cashew cream sauces have been a trend lately, I was so pleasantly surprised to find this Walnut version in Italy and to try out something different.

The traditional recipe uses bread to thicken the sauce, so I tried Gluten Free white bread from Trader Joe’s and it worked beautifully!  Of course, you can use regular white bread instead.  Cut off the crust of one slice and simply soak the bread in the milk for a few minutes.

Once the bread is soaked, add it and the remaining milk to the blender.  Also add to the blender the walnuts, parmesan cheese, ricotta, oregano, salt, garlic, and olive oil.  Then Blend it up!  It will be extremely thick, so you may need to scrape down the sides and loosen the mixture up at the bottom of the blender a couple times.  If it is still too thick to blend, add a tablespoon at a time of lukewarm water until it starts to blend smooth.  You can store the sauce in the fridge for up to a week.

COOK THE WALNUT SAUCE WITH PASTA AND SPINACH:

When you are ready to eat this amazing Walnut Sauce, pick your pasta and cook it according to pack instructions.  I used a Gluten Free Fettuccine that I love that’s made with brown rice flour, but you can use any pasta that you love in this recipe!  I have also used Wide Rice Noodles as fettuccine replacements before (see my Chicken, Tomato, Pepper, Pasta) and they work great!

Warm your sauce through in a skillet and then add the baby spinach.  Mix it so that the spinach begins to wilt, just a couple minutes.  Then add the drained pasta, but MAKE SURE TO SAVE SOME OF THE PASTA WATER.  As you mix the pasta into the walnut sauce you will find it extremely thick, which is how it should be.  However, you will probably want to thin it out a bit by adding a tablespoon of pasta water at a time until it reaches the consistency you want.

Finally season with salt and pepper to taste, plate and garnish with fresh grated parmesan.

ENJOY!  😍 Carrie
