Cajun Fettuccine Shrimp Pasta

I'm so excited to share this Cajun shrimp pasta with you! A few weeks ago, I was staring at my kitchen thinking about what to make for dinner when Donald mentioned how much he'd been missing shrimp. Honestly, I get it. Shrimp is one of those proteins that feels a little fancy but comes together faster than most weeknight dinners. Plus, it tastes like you spent way more time on it than you actually did.

Cajun Shrimp Pasta Ingredients

• 8 ounces penne pasta
• 3 tablespoons butter
• 1 clove garlic, minced
• 1 pint heavy cream
• 1 cup grated parmesan cheese

• Salt and pepper, to taste

• 1 pound large shrimp, peeled and deveined

About The Cajun Seasoning

I always use my own Cajun seasoning blend at home instead of relying on store-bought packets. Here's the thing about premade mixes, they can sometimes have more salt than you'd expect. Look for a good quality brand, or feel free to make your own by combining paprika, garlic powder, onion powder, cayenne pepper, and a pinch of black pepper. You can totally control the heat level this way.

How To Make Cajun Shrimp Pasta

Getting Everything Ready

Start by bringing a large pot of water to a boil. Once it's boiling, add your penne pasta and cook for about 8 to 10 minutes until it's al dente. Al dente means the pasta has a little bite to it, not mushy at all. Drain it and set it aside in a colander.

While the pasta is cooking, this is the perfect time to prep your shrimp. Make sure your shrimp is already peeled and deveined. Pat them dry with paper towels. This is actually really important because dry shrimp will brown nicely in the pan instead of steaming. I learned this tip the hard way after making shrimp that was pale and kind of sad looking.

Cooking The Shrimp

Heat 1 tablespoon of olive oil in a large skillet over medium heat. Once the oil is hot, season your shrimp with salt, pepper, and 1 teaspoon of Cajun seasoning.

Add the shrimp to the pan and let them cook without moving them around for about 2 minutes. This gives them a nice golden color on one side. Then flip them and cook for another 2 to 3 minutes until they're cooked through. You'll know they're done when they're pink and opaque all the way through.

Transfer the cooked shrimp to a clean plate and set it aside. Don't worry if they look a little undercooked. They'll finish cooking when we combine everything together at the end.

Making The Cajun Cream Sauce

Wipe out your skillet with a paper towel. You want it mostly clean so the sauce comes together perfectly. Add 3 tablespoons of butter to the pan over medium heat and let it melt completely.

Once the butter is melted, add your minced garlic and cook for about 30 to 45 seconds until it becomes fragrant. This is when your whole kitchen smells amazing, and honestly, that's half the reason I make this dish.

Pour in your heavy cream and add 1 tablespoon of Cajun seasoning. Stir everything together until the seasoning is mixed throughout. Bring the sauce to a low simmer. Don't let it boil hard or it might break, and we want that creamy, smooth texture.

Adding The Cheese

Now comes my favorite part. Working in batches, add your parmesan cheese to the simmering cream. Add a handful at a time, stirring frequently after each addition until that batch is completely melted. This takes a little patience, but it's so worth it.

Keep stirring and adding cheese until you've used about 1 cup total. The sauce should be getting thicker and creamier as you go. Continue cooking for another 1 to 2 minutes until the sauce coats the back of a spoon. When you run your finger across the spoon, it should leave a clear trail.

Putting It All Together

Add your cooked penne pasta to the cream sauce and toss or stir until every piece is coated. The pasta should be swimming in that creamy, golden sauce.

Taste a bite and add salt and pepper to your preference. Remember that the parmesan and Cajun seasoning are already pretty flavorful, so you might not need much more.

Add your cooked shrimp back into the pan and gently stir everything one more time. Serve the pasta in bowls and top each serving with extra parmesan cheese.

Storage And Reheating Tips

Store any leftovers in an airtight container in the refrigerator for up to 3 days. Honestly, this pasta tastes even better the next day because all the flavors have time to get to know each other.

To reheat, warm it gently in a skillet over medium heat, stirring occasionally. You might need to add a splash of cream or milk if the sauce seems too thick. Add it a little at a time until you get the consistency you want.

I don't recommend freezing this pasta because the cream sauce can get a little separated when thawed. It's still perfectly fine to eat, but the texture won't be quite the same as when it's fresh.

Tips And Variations For Your Cajun Shrimp Pasta

• If you prefer less spice, use only half the Cajun seasoning and taste as you go before adding more
• For more heat, add a pinch of cayenne pepper or a few red pepper flakes to kick things up
• Try using linguine or fettuccine instead of penne if you prefer a different pasta shape
• Add fresh spinach or sun-dried tomatoes to the sauce for extra flavor and color
• Use half and half instead of heavy cream for a lighter version, though the sauce won't be quite as thick
• Top with fresh parsley or chives for a pop of color and freshness
• Include sliced bell peppers or onions sautéed with the shrimp if you like more vegetables

Frequently Asked Questions

What Type Of Shrimp Works Best For Cajun Shrimp Pasta?

I always use large shrimp that are already peeled and deveined for this recipe. They cook quickly and stay tender when cooked properly. You can find them in the frozen section at most grocery stores, and they thaw in just a few minutes under cold running water. If you're buying fresh shrimp at the seafood counter, look for ones that smell like the ocean, not fishy. Sarah used to be really picky about shrimp, but once we started using good quality frozen shrimp from our local market, she completely came around.

How Can I Adjust The Spice Level In Cajun Shrimp Pasta?

For less spicy, start with just 1 teaspoon of Cajun seasoning total instead of the full 1 tablespoon and 1 teaspoon called for. You can always add more, but you can't take it out. If you want it spicier, add a pinch of cayenne pepper or red pepper flakes to the cream sauce. You could also use a spicier brand of Cajun seasoning if you like more heat. Donald likes his version with extra cayenne, so I always make his bowl a little spicier than the rest of ours.

Can I Use A Substitute For Heavy Cream?

You can use half and half, but the sauce won't be quite as thick or creamy. The pasta will still taste delicious, just a little lighter. Honestly, if you're making this pasta, the heavy cream is really what makes it special, so I'd stick with that if you can. I wouldn't recommend using milk or cream cheese because they just don't give you that same silky, luxurious texture.

How Do I Keep The Shrimp Tender And Not Overcooked?

The key is not moving them around too much in the pan. Cook them for about 2 minutes on the first side without touching them. Flip and cook for 2 to 3 minutes more. Shrimp cooks so fast, and overcooked shrimp gets rubbery and tough. Once they turn from gray to pink and opaque, they're done. I learned this when I first started making shrimp, and Alex had some that was chewy. Now I set a mental timer and stay focused while they're cooking.
