My Cajun shrimp spaghetti is saucy slow-cooked scrumptiousness, y'all. Browned Cajun trinity veggies and LOTS of garlic are simmered with tomato sauce and a dried bay leaf until a deep crimson-red gravy is achieved. Then, the seasoned shrimp gets added to the pot, and it all cooks down together until each piece is plump and melt-in-your-mouth tender. Yep and yay...

It's an Unforgettable Fusion of Fabulous Flavors...

Cajun shrimp spaghetti is a fusion dish that celebrates the locally caught seafood of our region. The classic Italian garlic-infused tomato sauce served over piping hot spaghetti element is there, y'all.

However, the rest of the flavors, including the Cajun trinity and south Louisiana-seasoned shrimp, are unique aspects that I use in my original version of this dish. The browned veggies deepen the base, while the shrimp set aside covered in seasonings injects each bite with a restaurant-quality taste and texture. 

This Cajun spaghetti with shrimp could not be easier, too, y'all! Once you cut the vegetables and season the shrimp the dish practically cooks itself. So, it's the perfect dinner to impress your people while remaining cool and collected before everyone sits down at the table. For sure!

Ingredient Essentials & Substitutions

  • I'm in the habit of buying peeled, deveined frozen shrimp. This simplifies my cooking life a whole, whole lot. All I do is defrost the shrimp in the fridge overnight to have it ready for recipe-making the next day. I also thaw it in cold water for a bit right before I use it. You can also run cold water over the frozen shrimp in a colander. That works, too.
  • There is a whopping ยผ cup of minced garlic in this Cajun shrimp spaghetti recipe. And, if I were you, I wouldn't change a thing. Nope. It's really the perfect amount, and if you use the jarred minced garlic like I usually do, then it's also incredibly easy. 
  • I hand-chop my Cajun trinity veggies. But, you can also pulse big chunks of each one of them in your blender or food processer, too. Just don't overdo it or the chopped onions, bell peppers, and celery will liquefy and become unusable. 
  • The spices and the bay leaf work in harmony to create the perfect flavor balance in each bite of this Cajun shrimp spaghetti. I recommend using all of them. But, if you can't find one then don't let it stop you from making the dish. Just make a point to buy all of the necessary spices to have on hand for the next time that you make it. 
  • I love and use Hunt's tomato sauce for everything, y'all. So, I'm never without it. You can use whatever tomato sauce you have on hand, though. As long as you already like the sauce then you will love this Cajun spaghetti with shrimp, too.
  • You can use any pasta shape that you like in this recipe. However, I've been eating this dish ALL of my life and I can tell you that long spaghetti is the best accompaniment for this dish.

Notes

Store the leftovers covered in the refrigerator for up to three days.
This dish freezes well if you use a vacuum-sealed bag. I only freeze the sauce for the Cajun shrimp spaghetti, not the pasta as it sometimes hardens and does not re-tenderize after thawing and heating. 
Use a digital meat thermometer to ensure that the shrimp temp up to at least 145 degrees Fahrenheit before consuming.
