You can double this recipe but don’t mix the pasta in the skillet; it won’t fit!
Cream sauces do not reheat particularly well, but the best way to do it is to reheat in a pot on the stove and add a little more cream.
Feel free to add red onion, bell pepper, or cooked chicken to the dish.

Step One: Cook the Pasta and the Meats

Start first by getting the pasta water boiling. Everything comes together quickly, so you’ll want that going right away. I prefer penne pasta but it’s totally up to you.

Start heating up the cast-iron skillet over medium heat. You’ll want it nice and hot before you start cooking the sausage so that it will brown. Place the sliced andouille sausage into the hot skillet and let it brown on both sides. While it’s cooking, toss the shrimp and cajun seasoning together in a small bowl. (Love your cast iron skillet? You’ll love smoky skillet pasta too!)

Once the sausage has browned, add the seasoned shrimp to the skillet. They will cook quickly, in just a couple of minutes. You don’t want to overcook them. Once they are cooked through, remove the sausage and shrimp to a clean plate.

Step Two: Make the sauce

There may be some cajun seasoning stuck to the pan. No worries. It will all be captured by the cream sauce in just a minute. Reduce the heat to low and pour the cream in. It will bubble a little, that’s okay. Scrape the bottom of the pan to make sure you get all the flavor into the sauce. Stir in the parmesan and the lemon zest. Let the sauce simmer for just a minute, until the parmesan is melted.

Step three: Assemble

Take the cooked sausage and shrimp and pour them right into the skillet. When the pasta is done, drain it and put it into the skillet as well. Serve it right away, with parsley and additional parmesan cheese if you’d like.

🔍 FAQs

What’s the best cajun seasoning for this?

If you make your own, great! If not, I like Louisiana brand.

Do I need to use heavy cream?

Yes! Milk or half and half will curdle when you make the sauce.

Can I use turkey sausage instead?


👩🏻‍🍳 Expert tips

  • Frozen shrimp is just fine for this recipe. Most grocery store “fresh” shrimp is just the thawed frozen stuff anyway.
  • Make sure you are taking care of your cast iron by seasoning it well!
  • Feel free to add red onion or bell pepper to this. Sautee them when you cook the meats, then add them back in at the end.
