Easy Cajun Shrimp With Tomato Alfredo Pasta Recipe

This easy Cajun shrimp pasta is one of those recipes that I threw together one night with what I had on hand. You know you’re running around the house doing stuff and suddenly realize it’s almost dinner time. You look in the pantry and fridge, throw some stuff together in a pot, and think okay let’s see how this goes!

But I thought to myself how could this dish not be super tasty!?! I love anything with Cajun shrimp and anything coated in Alfredo! If you haven’t noticed I’ve got other Cajun shrimp dishes on my blog like my Cajun Shrimp Tacos and Cajun Shrimp Foil Packs as well as a bunch of Alfredo pasta recipes too like my Chicken Fettuccine Alfredo, Salmon Alfredo, and Pasta Shells with Cauliflower Alfredo Sauce.

So let’s face it, Cajun shrimp tossed together with pasta and Alfredo sauce with tomato was not a stretch! I always say that some of the best recipes are the ones that we create in a pinch. And this Cajun Shrimp with Tomato Alfredo Pasta was no exception to the rule. It’s absolutely delicious with each creamy bite and the Cajun seasoned shrimp blend perfectly together with the tomato infused cheesy white sauce. It’s so darn tasty! 

• Pasta – Any dry pasta you’d like! Like fettuccine, linguine, mafalda, bow ties, whatever!
• Shrimp – Large shrimp, deveined with the shells removed.
• Cajun – I’m using my homemade Cajun seasoning today, I consider this spice blend a staple in my pantry!
• Olive oil and butter – Combining these two to brown our ingredients gives us all that brown butter deliciousness with none of that burnt butter bitterness.
• Onion – One small onion chopped up to be sautéed.
• Garlic – Use as much or little as you like.
• Tomatoes – You’ll need one can of crushed tomatoes, or if using diced, you can blend them up a bit in a blender.
• Cheese – Fresh Parmesan cheese grated up and sprinkled liberally!
• Cream – I used heavy cream today but feel free to use a different fat percentage if you’d like to make this dish lighter.
• Seasoning – Salt and pepper to taste.
• Basil – Fresh basil leaves chopped up.

This recipe for creamy Cajun shrimp pasta may sound a tad complex, but it’s actually really simple! Like most pasta dishes, you just boil some pasta and toss it with sauce. In this case, the sauce just happens to be an easy 15-minute tomato Alfredo that will blow your mind! 

Cook The Pasta

To start, you’ll need to bring a big large pot of salted water to a boil and cook the pasta according to the package directions. The most important thing when cooking pasta is to salt the water really well and to cook it to al dente. Then once it’s done, drain the pasta and set it aside for a later step.

Cook The Shrimp

While the pasta is cooking, it’s time to sauté some Cajun seasoned shrimp! First, generously sprinkle the shrimp with Cajun seasoning. You can even use your own Cajun Seasoning. Then heat 1 tablespoon of the olive oil over medium high in a large skillet.

Now, add the shrimp to the pan and cook them on both sides until they are pink in color. This should only take a few minutes time. Fully cooked shrimp are firm in texture and no longer translucent. Then when the shrimp are done remove them from the skillet and set them aside for now. 

Sauté The Onion And Garlic

Next, add the remaining 1 tablespoon of olive oil and butter to the same skillet once again and heat over medium high just until the butter melts. Then toss the chopped onion and garlic into the skillet and cook for about 3 minutes or until the onion is soft and translucent. 

Start The Sauce

Add the crushed tomatoes to the skillet with the onions and garlic and season with salt and pepper. Now, bring the mixture to a simmer. Then turn down the heat, and let it simmer for about 5 minutes while stirring from time to time. The mixture will thicken up as it simmers.

Finish The Sauce

Once the tomato mixture has reduced, stir in the heavy cream and parmesan cheese. Now allow the sauce to simmer for another 5 minutes. Then taste and season with salt and pepper as needed. You want the Alfredo sauce to be seasoned well to coat the pasta but not overly salty. So it’s best to just add a little salt at a time and taste with each addition.

Add The Pasta And Shrimp

Now that your sauce is perfect, add the cooked pasta and seared shrimp to the skillet. Then toss everything together to fully coat the noodles in the tomato Alfredo. You want each and every bite to be covered in the yummy sauce. Finally, garnish with some fresh basil and additional Parmesan cheese.

What Is Cajun?

When we’re talking about food, Cajun is usually referring to a spice blend which originated from Acadians living in Louisiana. Dry Cajun spice blend is made of paprika, cayenne pepper, herbs, garlic powder, onion powder, salt, and pepper.

How To Make Your Own Cajun Seasoning

Want to make your own jar of Cajun seasoning? Use my recipe here, it’s really easy, all you need are a few ingredients which you likely already have in your pantry.

How To Prep Your Shrimp

You’ll want to start at the small legs on the shrimp. Simply pull those off and the rest of the shell should start to release. Pull off the rest of the shell – but keep the tails on. To remove the vein along the top simply cut a slit with a small knife down the middle of the shrimp’s back before removing the black vein with the tip of your knife.

Alternatives

• Instead of shrimp you can use sausage, chicken or ground beef.
• Rather than diced tomatoes, crushed tomatoes will work beautifully
• To cut down on calories you can use half and half or a light cream.
• I used a type of pasta that’s shaped like calamari. Since that’s not super easy to find, you can use any type of pasta that you like.

Leftovers

This recipe will last well in an airtight container in the fridge for up to 3 – 4 days. If you’d like to freeze this recipe you may want to only make the tomato Alfredo sauce and store for up to 3 months, thaw in the fridge over night and make the pasta fresh as needed.

Notes

1. To cut down on calories you can use half and half or a light cream.
2. You can use sausage or ground beef if you don’t like shrimp.
3. Salt your pasta water. When cooking any noodles, you want to salt your cooking water really well to season the pasta. So use about one tablespoon of salt.
4. Use both the butter and olive oil. Make sure to use the olive oil with the butter. Doing so prevents the milk solids in butter from burning and becoming bitter.
5. Don’t cook the garlic on high. Never cook onions and garlic on high heat. It will cause them to brown and burn. They need time to soften and develop in flavor.
