Parsley Pesto Pasta with Peas

SPRING IS HEEERRRRREE! (Read that in Oprah’s excited yelling voice). As soon as that sun starts to shine and the days get a little longer I feel every cell in my body wake up and I instantly start craving super fresh flavors. This Parsley Pesto Pasta with Peas is a great “transitional” recipe to take you from cold grey winter days into the sunny days of spring. It tastes super bright and fresh, but doesn’t require a lot of really seasonal ingredients, which is nice because sometimes my brain is already screaming spring before the fresh produce hits the markets. :P

Parsley Pesto, a Budget-Friendly Alternative

I looooove making pesto with parsley because it’s a fraction of the cost of fresh basil. It has a super fresh, almost grassy flavor that I love. But if you’re not into parsley as much as I am (I admit, I LOVE parsley), you can use it in combination with other herbs to bulk up the pesto and bring the overall cost down. I also made my parsley pesto nut-free to reduce the cost even further, but you can add some walnuts, pine nuts, or sunflower seeds if you prefer a nutty pesto.

Other Pasta Add-Ins

In true Budget Bytes form, I kept this pasta dish super simple, but I have plenty of ideas for other add-ins if you want to take this up a notch. Asparagus and artichokes are also in season in the spring and would make a great addition, as would sun dried tomatoes, or even fresh grape tomatoes. You could even chop up some spinach and stir that right in, or purée it in with your pesto for even more bulk.

What Type of Parmesan is Best for Pesto

There is absolutely no question that Parmesan grated from a block is 100% better than the kind that comes grated in a bottle, but hey, that’s just not within everyone’s budget. I made my parsley pesto with the grated kind because I wanted to know that this dish was good even with the most widely available form of Parmesan. And yes, yes it is still very good!

Is Your Olive Oil Fresh?

Olive oil can go bad and bad olive oil will absolutely ruin a dish like this. Olive oil should never taste or smell sharp or bitter. So give your olive oil a little taste before you begin, just to make sure. If the oil does not taste smooth, it has probably gone rancid (the fat molecules have oxidized). Here’s a great little article about How to Tell if Your Food Is Rancid from Epicurious, if you want to read more.

How to Serve Parsley Pesto Pasta with Peas

Peas have a surprising amount of protein, so this dish makes a really great main dish on its own, especially if you add any of the add-ins suggested above. But I also think this pasta is the perfect side for burgers or any other grilled meat if you’re having a cook-out and enjoying the spring or summer weather. Super fresh!

Prep Time: 15 mins
Cook Time: 10 mins
Total Time: 25 mins
Servings: 4 to 6 servings


  • 1 bunch flat leaf Italian Parsley (about 2-3 cups, loosely packed) ($0.89)
  • 1 fresh lemon ($0.43)
  • 1/2 cup grated or shredded Parmesan ($0.88)
  • 2 cloves garlic ($0.16)
  • salt and pepper ($0.05)
  • 1/4 cup olive oil ($0.52)
  • 1 lb. pasta* ($1.99)
  • 1 cup frozen peas ($0.38)


  • Rinse the parsley well to remove any dirt or debris, then pat it dry with a clean, lint-free towel. Cut off the ends of the parsley stems and place the rest, leaves and stems, in the bowl of a food processor.
  • Zest and juice the lemon. Add half of the zest and about 2 Tbsp of the juice to the food processor, along with the Parmesan, garlic cloves (peeled), and some freshly cracked pepper (about 15 cranks of a pepper mill). 
  • Pulse the mixture until everything is finely minced and combined. Begin to add the olive oil in a thin stream through the chute of the processor as it blend the mixture together. Once the oil has been incorporated, add salt to taste. I added about 1/4 tsp salt.
  • Bring a pot of water to a boil for the pasta. Once boiling, add the pasta and continue to boil until the pasta is al dente. At the very end of the cook time, add the frozen peas and stir to combine. Let the peas sit in the hot water with the pasta for about a minute, then drain the pasta and peas in a colander.
  • Allow the pasta to cool just to the point where it is no longer steaming heavily. Transfer the drained pasta to a bowl and add the parsley pesto. Stir to combine, then serve warm. Add a pinch of the remaining lemon zest over top of each serving.


*I used casarecce pasta, but any short shaped pasta with texture would work great. You want to make sure to use something with texture so there is something to grab all the parsley pesto.

How to Make Parsley Pesto Pasta – Step by Step Photos

Washed and dried Parsley on a white towel

Begin by rinsing the parsley well to remove any dirt or debris. Sandy pesto is NOT fun (or good). Pat the parsley dry with a lint-free towel because watery pesto is also not good. Parsley stems are totally fine to eat and include in the pesto, so just cut off the ends and put everything else into a food processor.

Juiced and Zested lemon on a cutting board

Zest and juice one fresh lemon. This is the perfect use for any frozen whole lemons, if you have them stashed in your freezer! 

Pesto Ingredients in Food Processor

Add about half of the lemon zest, 2 Tbsp of the lemon juice, 1/2 cup grated Parmesan, 2 cloves of garlic (peeeled), and some freshly cracked pepper (about 15 cranks of a pepper mill).

Processed Parsley Pesto with no oil in the food processor

Pulse these ingredients together until they are minced and well combined.

Then slowly start to add 1/4 cup olive oil through the chute in the food processor as the ingredients are processing. Once done it should be a bright green saucy consistency.

Check out that color!! This stuff is seriously amazing. Now it’s time to add the salt and really make the flavors pop. Add salt to taste. I added 1/4 tsp.

Boiled Pasta and Peas draining in a metal colander

Bring a pot of water to a boil for the pasta. Once boiling, add 1 lb. pasta (I used casarecce, but any short textured pasta will do), and boil until the pasta is al dente. Once it’s tender, add 1 cup frozen peas and stir to combine. Let the peas sit in the hot water with the pasta for one minute, then drain in a colander. Let the pasta cool for a few minutes, or just until it’s no longer steaming heavily (you don’t want it to actually melt the Parmesan in the pesto).

Add Parsley Pesto to Pasta in a bowl

Once the pasta is slightly cool and well drained, transfer it to a large bow. Add the parsley pesto and stir to combine.
