Light Lemon Pesto Pasta Recipe
Spaghetti with Pecorino-Romano and Pesto Sauce
Ingredients
- 1 (16 ounce) package spaghetti
- 4 ounces Pecorino-Romano cheese, cut into cubes
- 6 cloves garlic
- 2 cups loosely packed baby spinach leaves
- 1 cup firmly packed basil leaves
- cup chopped walnuts
- cup lemon juice
- teaspoon lemon zest
- teaspoon salt
- 2 tablespoons olive oil
Directions
Step 1: Bring a large pot of lightly salted water to a boil. Cook the spaghetti in the boiling water until al dente, about 12 minutes. Drain the spaghetti and transfer it to a large bowl.
Step 2: Place the cubed Pecorino-Romano cheese into the bowl of a food processor. Process until the cheese is coarsely grated, which should take about 30 seconds.
Step 3: Add the garlic to the food processor and continue processing until the garlic is blended with the cheese.
Step 4: Add the spinach, basil, walnuts, lemon juice, lemon zest, and salt to the food processor. Process the ingredients together until the mixture forms a thick paste.
Step 5: Scrape down the sides of the food processor bowl with a spatula. With the food processor running, slowly drizzle the olive oil into the mixture. Continue processing until the olive oil is fully integrated and the sauce is smooth.
Step 6: Pour the pesto sauce over the cooked spaghetti and toss to coat evenly. Serve and enjoy!
Recipe Tip
If you have an abundance of basil, you can increase the amount of basil to 3 cups for a stronger flavor.

Thanks so much AR for correcting the amount of lemon juice! You guys rock! My submitted recipe called for 1/4 cup lemon juice- I let AR know about it an they corrected the recipe! I recommend tossing the pesto with hot pasta so the cheese sort of melts and coats each strand. You might want to reserve a ladle or two of hot pasta water so you can add a little while tossing if you want a saucier dish.

Soooo good. This makes a really fast, easy, and delicious dinner. I toasted the walnuts and garlic before adding them; used farfalle instead of spaghetti; and added some chopped grape tomatoes. Paired this with a pork loin for a wonderful dinner! Thank you for the recipe!

This was amazing! Still is, actually. I froze the left overs in an ice tray, popped them out once frozen, wrapped them individually in plastic wrap, and put them into a freezer bag and back into the freezer. It's just as delicious as the day I made it. They're the perfect single serving size and very convenient if you want a taste of summer all year round. I also reserved some pasta water to add to it to make it creamier.

6 cloves is WAY too much garlic. 1 small clove is fine. I followed other reviews and reserved some pasta water to add to the final product. It really helps melt and incorporate everything. I use the whole lemon, zested and juiced. Great summer recipe! 1 star as written, 5 starts with less garlic.

I used cashews (because of a walnut allergy) and cut back the garlic to 3 cloves and the end result was perfect! Thank you for sharing this recipe because I have never found one I like ready made from the store, and now I will be making this regularly for the family!

We LOVED this. Delicious, easy. enough for feed 4-5. Only suggestion is to add 1/4 cup of the pasta water to the pesto and noodles to make it a bit creamier.

My family thought this recipe was fantastic and my mother asked for the recipe. We did use only 4 cloves of garlic as we thought 6 would be excessive. I also added in some pine nuts, as I did not have quite enough walnuts. I blended it all in my Nutribullet , by adding ingredients a bit at a time. I also did add almost 8 ounces of chicken broth as this device will not blend without some liquid. I do not think the broth affected the over all flavor. I will definitely make this again and will probably add some shrimp or chicken and maybe roasted tomatoes. Yummy!

So good! I made zoodles and cooked them in pan for about 5 minutes, drained the juice from them and tossed with this pesto. Hubby loved it!

Possibly my new go to pesto recipe! Thank you! I was never a huge pesto fan, but figured I would try something I rarely make and stumbled upon this recipe. I will be making it again with out a doubt. Light, and full of flavor. I used some extra lemon, and pine nuts instead of walnuts because I had them on hand. I also marinated a couple chicken breasts in a chipotle pepper mix, baked and then cubed and tossed that over the pasta. Very tasty!!

Delicious! But I do have to agree, holy garlic! I’ve got a wife that’s not a huge fan of spice and a toddler and had to do a lot of doctoring to try and cut the garlic. I will definitely make again but might start with half the amount of garlic and see where it gets me.

I personally prefer to roast the garlic in my air fryer before using it in this recipe. It’s much more flavorful than raw garlic. I also like pignoli nuts better.

This was a delicious pesto. We followed the recipe to a t, and were very happy with the flavor of it. Since the garlic in it is raw, it does have a pretty strong garlic taste that does linger afterwards, so I agree with the others that if you don't love garlic, use less of it. I would definitely make this again!

Reviews mentioned that the amount of garlic was too much. My family loves garlic, so we thought it was the perfect amount.
