Tips for This Recipe

Use Your Favorite Noodles

We've used spaghetti noodles for this recipe, but you can swap them out for 12 - 15 ounces of your favorite noodles. Popular alternatives include: penne, bowtie, or Rotini.

Cook Your Noodles Al Dente

For this recipe you'll cook your pasta noodles according to the instructions on their package. Finish cooking the pasta 1 - 2 minutes earlier (sometimes more) when it's just barely cooked so that it's al dente: still firm in the middle. This will allow the pasta to better hold shape when mixed with the other ingredients.

Mix Everything in a Bowl

After you drain your pasta noodles, you'll mix them in a bowl with the remaining ingredients. You don't want to mix everything in the pot that the noodles were cooked in because it will be hot, which can cause your pesto to wilt & brown.

Is Pesto Pasta Vegan?

Most pesto is not vegan and contains eggs. If you want to make this recipe vegan, use a vegan pesto sauce (like this one) or make your own (like this recipe).
