I was going to share another recipe today, but I’m so excited about this pasta that I just had to share it. Sometimes recipes take a long time to think up. Sometimes they take a long time to fully develop, but this was quick and easy. I got the idea to make a spicy, cajun-style shrimp pasta. But instead of making it super creamy and heavy, I wanted to make it with some more wholesome ingredients.

I made a few simple and easy swaps. The I added in so much color, plus some crispy, spicy shrimp, and my favorite homemade pesto pasta.

This dish comes together in minutes and it really is so delicious.

The details on the pasta

I like to start with the pasta since the shrimp cooks up so quickly. I made my favorite basil pesto. The secret is to use a little jalapeño for an unexpected but delicious spicy kick. I know it sounds odd with all these Italian flavors, but if you love a Greek goddess style dressing, you’ll love this pesto. It’s very similar.

I like to toss in some arugula in addition to the basil. This adds vibrant color, flavor, and some much needed healthy greens!

When the pesto is made, boil up your favorite cut of pasta. I really like using a longer cut…fettuccini or bucatini are my usual go-to’s. But something short-cut, like bow ties, is great with the shrimp too. You really can’t go wrong.

Add the hot pasta right back to that pot you boiled it in, then add all the pesto, and a splash of creamy coconut milk. The coconut milk helps to create a luscious sauce without adding in any cream. You don’t taste even the slightest hint of coconut!

That spicy shrimp

I usually cook the shrimp while the pasta is boiling. It takes just a few minutes, so the timing is perfect.

The shrimp is pan seared in olive oil with cajun seasonings until both sides are browned. I love to make my own homemade cajun spice mix, but if you’re in a pinch, store-bought works too. Add a small pat of butter and a squeeze of lemon. They go a long way flavor-wise, especially with all the spices and garlic. Everything pairs so well together.

To serve, I usually plate the pasta, then spoon the shrimp and any sauce left in the skillet over the noodles. This gives a nice, pretty presentation! Or, you can do it like my dad and simply toss everything together. Keep it simple.

Either way, is so good. Both the shrimp and pasta have so much flavor on their own. But put them together and you create a wonderfully delicious pasta plate.

  • 1. To make the pesto. In a food processor, combine the basil, arugula, jalapeño, 1 clove of garlic, the nuts, parmesan, and 1/4 cup olive oil. Season with salt. Pulse until a sauce forms, adding 1-2 tablespoons water if needed to thin.
    2. Bring a large pot of salted water to a boil. Add the pasta and cook according to package directions until al dente. Just before draining, remove 1/2 cup of the pasta cooking water. Drain and add the pasta right back into the hot pot.
    3. Add the pesto and coconut milk, tossing to combine. Thin the pasta as desired with the reserved pasta cooking water. 
    4. Meanwhile, make the shrimp. Heat the olive oil in a large skillet over medium heat. Add the butter, shrimp, cajun seasonings, and a big pinch of pepper. Cook on both sides until seared, about 2-3 minutes per side. Stir in the garlic, cook until fragrant. Remove from the heat, stir in the lemon juice.
    5. Toss the shrimp with the pasta. Grab a fork and enjoy!

    So easy and delicious! We used store-bought pesto but will definitely make the homemade version next time. Literally the easiest meal to throw together and barely any clean up which we love. Used whole milk + a tiny bit of butter in place of coconut milk and it made the pasta creamy and delicious.

    1. Hi Ally,
      Happy Sunday!! Love to hear that you have enjoyed this recipe, thanks so much for making it!! xx

  2. Tieghan, a famous chef Massimo Bottura, when he makes his pesto uses water too, he suggests ICE water as it cools down the herbs and keeps them vibrant green. He puts a dash of mint and thyme in his and he also suggests to put the herbs in the water when you are cooking your pasta.
    I love you use water in your pesto
