Mexican Pesto Pasta with Shrimp


I love a good pesto.  They are packed with bold flavor, easy to pull together and completely customizable to any recipe theme.

A basic pesto is basil, pine nuts, garlic, parmesan and olive oil.  You can’t go wrong with the classic, but why stay there? You could swap the basil for parsley, kale, spinach, collard greens or cilantro as we have here. Pine nuts can be pricey and a little more difficult to locate than their more common counterpart – walnuts, always a good substitute in a pesto. I’ve played around with a few different versions, I’m sure  you’ll see more recipes sneak in on this blog, but this one has quickly held it’s place at the top of my list.  The pepitas and cilantro play together nicely for a light summer dinner when paired with the angel hair pasta and shrimp tossed in cumin and lime.

Have you ever played with pesto? What’s your go-to combination or favorite flavor find?

Mexican Pesto Pasta with Shrimp

  • 1 cup raw pepitas
  • ½ cup raw pecans
  • 2 bunches cilantro
  • 2-3 cloves garlic
  • ½ cup grated parmesan
  • EVOO
  • ¼ – ½ cup half and half
  • 1 pound shrimp, peeled and deveined
  • 1-2 tsp cumin
  • 1 lime, zest reserved
  • Angel hair pasta
  • 1-2 tablespoons unsalted butter
  • ½ cup white wine

Start by making the pesto.

*First a note about the nuts used in this pesto: Pepitas are just pumpkin seeds. I was able to locate them, both raw and roasted & salted, in the bulk section of my local grocery store.  If you can’t locate pepitas, this pesto is just as tasty with all pecans or a mix of pecans and walnuts.

You want to toast the pepitas and pecans to develop their nuttiness a little and make for a more flavorful pesto.  Starting with raw nuts that haven’t been toasted or salted yet helps you to control those elements as you cook. To toast the nuts, simply place them in a dry skillet over medium heat.  Stir the nuts every few minutes, keeping close by – you’ll know the nuts are ready to pull when you can smell them!  Don’t leave them too long after you catch their aroma, they can quickly go too far and taste burnt.


Place the toasted nuts in a food processor and add the cilantro, garlic and parmesan.


Stream in the olive oil (EVOO) with the food processor on low until the pesto is a paste to the consistency of your liking.  I prefer the pesto to be well-chopped and more on the thick side than a normal thinner pesto before adding the half-and-half.  Taste the pesto and add salt, freshly ground pepper and parmesan, as needed.  If you want to kick it up a bit, this would be a good time to add in red pepper flakes.  With or without the red pepper flakes, a touch of granulated sugar, up to about a teaspoon,  will help balance flavors and bring your pesto together.  Play with the flavors a bit until you get what you are looking for!


Place the pesto in a bowl.  Stir in the half-and-half and check the seasoning again,  adjusting if necessary.  Set the pesto aside as you prep the shrimp and cook the pasta.


Bring a large pot of water to a boil.  Add a healthy amount of salt to the water – this is your chance to flavor the pasta itself.  Cook the angel hair pasta to al dente.

Season the prepared shrimp with the cumin, salt, pepper and lime zest.  If you are not quite ready to cook the shrimp, hold off on adding the lime juice until right before they are ready to hit the pan.  Citrus juice will ‘cook’ seafood as it sits together (think: ceviche) and this is not quite what we are going for here.  We want the lime juice to flavor the shrimp as it sears instead.

Saute the shrimp in the butter, a couple minutes per side. When cooked, remove the shrimp to plate and set aside.


Deglaze your pan with the white wine.  You can use any white wine here… just remember this one rule:  cook with wine you would drink.  Reducing the wine intensifies the flavor, so if you wouldn’t drink it, you shouldn’t eat it 😉  Tonight, I’m drinking/eating Joel Gott Sauvignon Blanc – I tend to enjoy any varietal from the Joel Gott family and they are reasonably priced and easy to find in my grocery store.


Once the wine has reduced a bit and you have stirred up all those tasty brown bits from the bottom of the pan, add the cooked and drained pasta to the skillet.  Toss it around to coat the pasta with the pan sauce.


Turn off the heat source and stir in the creamy pesto, a little at a time, until the pasta is coated and to your desired consistency.  I typically work in 1 1/2 – 2 cups of the pesto.

*Storage tip for leftover pesto: To store any remaining pesto in the fridge, place the pesto in a sealable container and smooth over the top.  Cover the entire top of the pesto with EVOO, place the lid on the container and store in the fridge for 3-4 days.  You can also freeze the pesto at this point.  The EVOO protects the pesto from browning, leaving it that vibrant green for your next cooking adventure.


Top the pesto pasta with the cooked shrimp.  Sprinkle on extra parmesan and chopped cilantro, if desired, and enjoy!

*To change it up and enjoy your grill in the summer:  a nice update to this recipe would be to grill the shrimp for an added char to the shrimp.  Cut back a little on the garlic in making the pesto and then saute some fresh, chopped garlic in the 1-2 tablespoons of  butter in a skillet.  When toasted, add the wine to deglaze and follow the original recipe from there!
