Ready fast and delicious to boot! Our 20 Minute Pesto Pasta is a family favorite! We’ve been making pesto for a very very long time now, but have just recently gotten around to sharing this week. Trust me, if you haven’t made our Easy Classic Pesto yet, you’re going to want to get on that for this recipe. It really makes the world of difference for this easy but absolutely delicious vegetarian pasta!

Ingredients Needed

spaghetti pasta, salt, Parmesan cheese, and a bowl of pesto labeled.
  • Pasta – Spaghetti is a favorite, and homemade pasta, well that just takes it all to the next level, but you can also of course use any of your favorites.
  • Homemade Pesto Store bought is also fine, but once you realize how it’s almost as much time to open a jar as it is to make your own, trust me, the difference in the flavor is worth it!
  • Parmesan Cheese – Just enough to finish your plate with! Another hard cheese like Asiago or Romano will also work well.
  • Salt – This is to generously salt the pasta water, as you should always when cooking pasta!

Easy to Make

It doesn’t get much easier than this, really. Cook your pasta to either the package instructions, or just for a few minutes if you’re going the extra mile and using Fresh Homemade Pasta. Add some of that pasta water to your pesto to loosen it, and then it’s ready to be added to the pasta when it is cooked and drained.

Pasta Water

Don’t skip the pasta water! This is key for any pasta recipes where you want the ultimate cling of the sauce to your pasta. That’s thanks to the starchy goodness that’s in that salty pasta water. Be sure to grab it before you drain your pasta – I’ve made that mistake and it’s a heartbreaking one!

Instructions

Notes

Storage
Fridge: This pasta will last in the fridge for 3-5 days. 
Freezer: It will freeze up to 2 months, although it’s best to freeze homemade pesto and then just make the pasta fresh. 
Substitutions
Pasta: Spaghetti is one of our favorites, but you can use any of your favorites. Just be sure to check the cook times on whatever type of pasta you’re using. Go the extra mile and use Fresh Homemade Pasta! 
Pesto: Our homemade pesto is our favorite, but you can of course use store-bought. 
Pasta Water
Setting aside a bit of pasta water is key to ensuring that the pesto clings to the pasta. We only add 1/8 of a cup to the pesto, but you can add up to 1/4 for a looser pesto with the pasta. You can also add a little bit of added olive oil, too if desired.
