What is cajun seasoning made of?
Cajun seasoning is a spice mixture containing spices such as garlic powder, paprika, salt, onion powder, cayenne, oregano, thyme, red pepper flakes, and pepper!
It’s slightly sweet, it’s perfectly spicy, it’s ridiculously flavorful, and it makes this Cajun shrimp pasta SO GOOD!
This recipe is packed with veggies, pasta, cheese, shrimp…it’s got everything!
- Unsalted Butter – melted and used to cook the veggies.
- Yellow Onion, Green Bell Pepper, Red Bell Pepper, Orange Bell Pepper, and Baby Bella Mushrooms – a delicious, colorful veggie blend that adds texture, flavor, and gives this pasta dish an extra boost of nutrition.
- Garlic – adds a subtle nutty flavor to round out the sweeter flavors from the veggies.
- Half-and-Half – the base of our sauce. Half-and-half creates a rich, cream sauce without being overly heavy. Want it even creamier? Use heavy cream!
- Parmesan Cheese – thickens our cream sauce while also providing a sharp, salty flavor. Use finely grated parmesan for the smoothest texture.
- Shrimp – use raw, peeled and deveined with tails taken off. If using frozen shrimp, be sure they’re completely thawed before proceeding with the recipe.
- Penne Pasta – cooked al denté according to package directions.
- Homemade Cajun Seasoning – Garlic Powder, Paprika, Salt, Onion Powder, Cayenne Pepper, Oregano, Thyme, Red Pepper Flakes, and Black Pepper. This blend of spices make up a sweet, spicy, super flavorful seasoning mix!

What pasta to use
Any pasta would be great in this cajun shrimp pasta recipe. I use penne pasta, because I love how the sauce gets into the middle of the tubes and also coats the outside of the pasta.
However, I think any pasta you have on hand will work. Try, rotini, rigatoni, linguine, etc. Whatever pasta you use, be sure it’s cooked al denté.
Do you use fresh or frozen shrimp?
Fresh or frozen shrimp can be used in this recipe. Whatever you use, use large shrimp that’s been peeled, deveined, with the tails removed. I find that smaller shrimp become easily overcooked while the sauce thickens.
If using frozen shrimp, be sure to thaw it completely before proceeding with the recipe.
How to thaw frozen shrimp
I always recommend following the directions on whatever package of shrimp you have, but the general rule of thumb is to submerge the shrimp in cool water for 10-30 minutes or in the fridge overnight.
