Notes
Ingredients for Creamy Cajun Shrimp Penne
Here’s everything you’ll need to make this flavor-packed dish, I promise it’s all simple stuff you might already have! (Pro tip: prep everything before you start cooking, this moves fast once you begin.)
For the Pasta:
- 12 oz penne pasta (or whatever short pasta you’ve got, I’ve used rigatoni in a pinch!)
For the Shrimp and Sauce:
- 1 lb shrimp, peeled and deveined (size 31/40 works perfectly, not too big, not too small)
- 2 tbsp olive oil (the good stuff, it makes a difference!)
- 2 tbsp Cajun seasoning (my secret is Tony Chachere’s, but use your favorite brand)
- 3 cloves garlic, minced (fresh is best, none of that jarred stuff here)
- 1 cup heavy cream (yes, really, this is where the magic happens)
- 1/2 cup chicken broth (low sodium if you can)
- 1/2 cup grated parmesan (please, please get the real stuff, not the green can)
- 1 tbsp cornstarch + 1 tbsp water (our sneaky thickening trick)
- Salt and pepper to taste (you won’t need much salt with that Cajun seasoning doing its thing)
Equipment Needed
- Large pot (for boiling that pasta)
- Skillet (big enough to hold everything, I use my 12-inch)
- Whisk (for that silky smooth sauce)
How to Make Creamy Cajun Shrimp Penne
Okay, let’s get cooking! I promise this comes together faster than you’d think, just follow my lead and you’ll be twirling that perfect bite of pasta in no time.
Cooking the Pasta
First things first, get that water boiling! I always salt it like the sea (Grandma’s rule) and cook the penne for 1 minute less than the package says. Why? Because it’ll finish cooking in that glorious sauce later. Drain it but don’t rinse, we want all that starch to help the sauce cling.
Preparing the Shrimp
Heat your oil in that big skillet over medium-high, you’ll know it’s ready when a drop of water sizzles. Toss the shrimp with Cajun seasoning (get them all coated evenly!) and cook just until they turn pink, about 2 minutes per side. Here’s the key, pull them out when they’re almost done since they’ll keep cooking in the sauce. Nobody wants rubbery shrimp!
Making the Sauce
Same skillet (don’t wash it, all those browned bits equal flavor!), add the garlic and let it get fragrant for about 30 seconds. Then pour in the cream and broth, it’ll bubble up beautifully. Now the magic: whisk that cornstarch slurry in to thicken things up, then stir in the parmesan until it’s all melty and dreamy.
Bringing It All Together
Return the shrimp to the skillet, add the pasta, and toss everything like you mean it! I use tongs to really coat each piece. Taste and adjust with salt and pepper if needed (though that Cajun seasoning usually does the job). The sauce should be clinging to every noodle, not too thick, not too thin. Perfection!
Tips for Perfect Creamy Cajun Shrimp Penne
- Spice control: Start with 1 tbsp Cajun seasoning if you’re sensitive, you can always add more!
- Shrimp watch: They cook fast! Take them off heat when they curl into a “C” shape.
- Sauce rescue: If it gets too thick, splash in some pasta water to loosen it up.
- Toss, don’t stir: Folding gently keeps the shrimp from breaking apart.
Serving Suggestions for Creamy Cajun Shrimp Penne
This dish shines all on its own, but I love pairing it with garlic bread to soak up every last drop of sauce! A simple green salad cuts through the richness perfectly. For special occasions, I’ll add roasted asparagus, the flavors just sing together.
Storage and Reheating
Here’s the good news, leftovers taste even better the next day! Store any extra in an airtight container in the fridge for up to 3 days. When reheating, splash in a little milk or cream and warm gently over low heat, this keeps that sauce luscious instead of drying out. (Pro tip: the microwave works too, just stir every 30 seconds to distribute heat evenly!)
Nutritional Information
Just a heads up, these numbers are estimates (my shrimp might be bigger than yours!). One serving packs about 580 calories with 32g protein and 28g fat. That creamy sauce gives you 14g saturated fat, but hey, life’s too short to skip the good stuff! For more recipe ideas, check out recipesloop.com.
Frequently Asked Questions
You’ve got questions, I’ve got answers! Here are the things people ask me most about this Creamy Cajun Shrimp Penne:
Can I use frozen shrimp?
Absolutely! Just thaw them overnight in the fridge or under cold running water first. Pat them super dry before seasoning, wet shrimp won’t get that nice sear. I always keep a bag in my freezer for last-minute pasta nights! If you are looking for other shrimp recipes, check out my creamy garlic shrimp pasta recipe.
How can I make it spicier?
Oh, you like it hot? Add a pinch of cayenne with the Cajun seasoning, or toss in some diced jalapeños with the garlic. My friend Mike swears by adding a dash of hot sauce at the end, just taste as you go!
What other pastas work besides penne?
Any short pasta with nooks for sauce is perfect! Rigatoni and fusilli are my top picks, but I’ve even used farfalle (bowties) when that’s all I had. Long noodles like fettuccine work too, just twirl away!
