Equipment
-
Large pot
-
cast iron skillet
-
Colander
-
Measuring spoons
-
Zester or microplane
-
small bowl
-
Grater
Ingredients
- ½ pound penne pasta
- 1 pound large shrimp (peeled and deveined)
- 8 ounces andouille sausage (sliced)
- 1 tablespoon cajun seasoning
- 2 tablespoons butter
- ¾ cup heavy cream
- ½ teaspoon lemon zest
- ¼ cup grated parmesan cheese
- salt and pepper to taste
Instructions
-
Cook the pasta. Bring a large pot of salted water to a boil. Add the penne and cook until al dente according to package directions, usually 9–11 minutes. Drain, reserving about ¼ cup of the pasta water, and set aside.
-
Season the shrimp. Toss the shrimp with the Cajun seasoning in a small bowl so they’re evenly coated. Let them rest briefly while you prepare the sausage and heat the skillet.
-
Cook the sausage and shrimp. Heat a large cast iron skillet over medium. Add the sliced andouille and brown for 3–5 minutes, letting it develop color without constant stirring. Add the seasoned shrimp and cook about 1–2 minutes per side until pink and opaque. Remove sausage and shrimp to a plate and set aside.
-
Make the cream sauce. Reduce heat to low and add the butter to the skillet. Once melted, pour in the heavy cream and stir, scraping up any browned bits. Add lemon zest and Parmesan, and let the sauce simmer gently 1–2 minutes until it thickens enough to coat the back of a spoon.
-
Combine everything. Return the sausage and shrimp to the skillet and taste, adjusting salt and pepper. Add the cooked pasta and toss so the sauce coats evenly. If the sauce seems too thick, loosen with a splash of reserved pasta water.
-
Serve. Plate immediately and garnish with chopped parsley and extra Parmesan if desired.
Notes
To make the sauce creamier, add a touch more heavy cream or a splash of pasta water. The starch in the pasta water helps the sauce cling to the pasta.
Taste the sauce before combining and adjust seasoning with salt, pepper, or a squeeze of lemon for brightness.
Feel free to add vegetables—sautéed bell pepper, red onion, or spinach work well and add color and nutrition.
Because Cajun seasoning varies in heat, start with less and add more to suit your spice preference.
Reduce heat before adding cream; high heat can cause the dairy to separate. A gentle simmer keeps the sauce smooth and rich.
Freshly grated Parmesan melts more smoothly than pre-grated and gives a better flavor and texture to the sauce.
Garnish with fresh parsley or basil for a bright finish.
Nutrition
This pasta has become my go-to for busy nights—smoky sausage, tender shrimp, and a creamy, slightly spicy sauce that’s ready quickly and uses just one pan. Because everything cooks in the skillet, cleanup is quick, leaving more time to enjoy the meal. It’s a dependable, flavorful option when you want comfort food without a lot of fuss.
I’m confident you’ll enjoy it as much as I do.
Tips for the Best Cast Iron Skillet Cajun Pasta
- Have ingredients prepped before you start—peel shrimp, slice sausage, and measure spices to keep the cooking smooth and fast.
- Let shrimp, sausage, and cream sit at room temperature for 10–15 minutes for more even cooking and to help the cream integrate without splitting.
- Pat shrimp dry before cooking for better browning and texture.
- Use a cast iron or heavy skillet for consistent heat and better browning; avoid nonstick if you want a deeper sear.
- Cook in batches if needed—crowding the pan causes steaming instead of browning.
- If the sauce is too thick, thin it with reserved pasta water; the starch helps the sauce cling to the pasta.
Key Ingredients and Tools
Below are the main items that shape the dish’s flavor. Most are easy to find and each contributes to the final result.
- Shrimp: Choose large shrimp, fresh or thawed if frozen. Peel and devein before cooking for the best texture.
- Andouille sausage: This smoked, spicy sausage gives the dish its characteristic Cajun flavor. Smoked sausage or kielbasa can be used as substitutes.
- Cajun seasoning: A mix of paprika, garlic powder, and cayenne. Adjust to taste or use a milder custom blend if preferred.
- Heavy cream: Creates the rich, silky sauce. Half-and-half can work in a pinch but will yield a lighter sauce.
- Cast iron skillet: Ideal for even heat and browning. If unavailable, use a heavy-bottomed skillet for best results.
- Lemon zest: Adds brightness that balances the richness of the sauce—use fresh zest for the best flavor.
Serving Suggestions
Serve with garlic bread, a simple green salad, roasted vegetables (broccoli or asparagus), cornbread, or grilled zucchini for a complete meal.
Troubleshooting and Help
You can, but add pre-cooked shrimp at the end to warm them gently; they can become rubbery if reheated too long.
Yes. Penne holds the sauce well, but fusilli, rigatoni, or fettuccine all work—cook to al dente so the pasta keeps its texture when mixed with the sauce.
Absolutely. Bell peppers, spinach, or cherry tomatoes are great additions; sauté them with the sausage so everything finishes together.
It has a pleasant kick but isn’t overpowering. Reduce Cajun seasoning if you prefer less heat, or add extra cayenne for more spice.
Swap heavy cream for half-and-half or a dairy-free alternative like coconut milk; the sauce will be lighter but still tasty.
Yes—use your favorite gluten-free pasta and follow the recipe as written.
It’s best fresh, but you can store the pasta and sauce separately and reheat gently, adding a splash of cream to revive the sauce.
Storage Instructions
Store leftovers in an airtight container in the refrigerator for up to 3 days. Reheat gently on the stovetop or in the microwave with a splash of cream or milk to restore creaminess. This dish doesn’t freeze well—cream-based sauces can separate when frozen and reheated.
This recipe brings bold flavors and simple preparation together: smoky sausage, tender shrimp, and a rich, spicy sauce ready in about 30 minutes. It’s a satisfying one-pan meal that’s perfect for busy evenings.
