This bowl of Cajun Garlic Butter Shrimp with Creamy Pesto Pasta is THE best any night of the week winter pasta. Taking a classic pesto pasta recipe and updating it with a no-cream, creamy pesto sauce, spicy garlic shrimp, and fresh greens. Every twirl of pasta has delicious and comforting fresh flavors that melt in your mouth. This is such a cozy, creamy bowl of shrimp and pasta.
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.

I made this tonight and it was another WINNER! Tieghan, thank you so much we love your recipes
Hi Stefanie,
Happy Friday!! Love hearing that this recipe was enjoyed, thanks a bunch for giving it a try! xxT
Yummy. I added some fresh tomatoes for a little added color, but the pesto and shrimp were spot on. Made 1.25# fresh pasta and maybe used 3/4 pound with the sauce. Definitely recommend the jalapeño! Thanks, Tieghan!
Hey Liz,
Happy Friday!! Love hearing that this recipe was enjoyed, thanks a bunch for giving it a try! xxT
Delicious! I made this last night and made the exact recipe. The pesto was different enough from my traditional basil/walnut version and was perfect with shrimp. I agree with you and also make my own Cajun spice mix.
I used angel hair pasta and I forgot how much pasta that makes so if you use that, I would only make a 1/2 pound.
Very delicious and enough kick to keep it interesting.

It doesn’t say in your recipe but can you put the cajun seasoning on the shrimp prior to cooking it in the cast iron skillet? It seems like this would coat it more evenly than just putting the seasoning in the pan.
Hey Sandra,
Totally, that will work well for you! Please let me know if you give this recipe a try. I hope you love it! xTieghan
Is it ok to use a store bought pesto and add the arugula?
Hey Kimberly,
Totally, that will work well for you! Please let me know if you give the recipe a try, I hope you love it! xTieghan
Made this tonight, with the store bought pesto, I added fresh spinach instead of arugula into the pesto. Amazing!!! Boyfriend and I both loved it. A definite in the menu rotation.
PS:. This is the fourth or fifth recipe I’ve used of yours. Thank you so much.
Hey Kimberley,
Awesome!! Love to hear this recipe was a winner, thanks for making it. Have the best week:) xT
This was so easy to make – inspirational to add arugula to pesto. I omitted jalapeno…perhaps next time!
Mixing together with shrimp & pasta…not a bite left on the plate. Had some pesto left, so shall use tonight with the marinara mix!
DELICIOUS
This was an awesome recipe for diabetics when we used De Cecco thin spaghetti. We were staying in Key West and used fresh pink shrimp…soooo delicious. We used 2 lbs of shrimp per 1 lb of spaghetti. Also added 1 tbsp chili lime seasoning.

Hey Gretchen,
Thanks so much for making this recipe, I am thrilled to hear it was enjoyed. Thanks for sharing your comment! xTieghan
This was so delicious and pretty easy for a weeknight meal! First time making homemade pesto sauce and I especially loved the kick from the jalapeño. I used homemade Cajun seasoning and accidentally used the entire can of coconut milk before seeing it’s only 1/4 cup. It was so creamy and tasty! My two year old ate some of the pasta without shrimp and my husband had seconds!
