This Cajun shrimp and sausage pasta earns its spot in the weekly rotation because it tastes like a restaurant splurge but comes together in one skillet with pantry spices you probably already own.
The trick is building layers: seared sausage for depth, shrimp kissed by high heat for sweetness, and a lightened-up cream sauce that clings to every noodle without weighing you down. I keep the spice blend mild enough for the whole table and let everyone add hot sauce at the end.
If you've never cooked shrimp before, this is the recipe to start with. It's forgiving, fast, and the whole pan smells like a Louisiana kitchen on a Sunday.
Why You'll Love This Recipe
About the Ingredients
12 oz (340 g) penne or rigatoni pasta
Short tubes hold the sauce best. No penne? Use fusilli or farfalle; they cup the sauce just as well.
1 lb (450 g) raw large shrimp, peeled and deveined, tails off
Frozen shrimp work great, just thaw overnight in the fridge and pat very dry. Look for 21-25 count per pound for even cooking.
12 oz (340 g) smoked turkey sausage or andouille, sliced into 1/4-inch rounds
Turkey sausage keeps it skinny; andouille gives a deeper Cajun punch. Either way, slice on the bias so the rounds brown nicely.
1 tbsp olive oil
Any neutral oil works. If using a nonstick skillet, you can cut this to 2 teaspoons.
1 medium yellow onion, diced (about 1 cup)
Red onion is a fine swap for a sharper bite. Frozen diced onion saves 5 minutes on busy nights.
1 medium red bell pepper, diced (about 1 cup)
Green bell pepper is the classic Cajun choice; use it if you want a more traditional flavor.
3 cloves garlic, minced
Jarred minced garlic works in a pinch, use 1 tablespoon. Add it last so it doesn't burn.
1 tbsp Cajun seasoning, plus more to taste
Check the label, many blends are salty. If yours is, skip the added salt until the end.
1 cup (240 ml) low-sodium chicken broth
Vegetable broth is a fine substitute. Swirl a splash of the pasta water in the empty carton to get every drop.
1 cup (240 ml) half-and-half
Whole milk plus 1 tablespoon cornstarch is a good lighter swap. For dairy-free, use canned coconut milk.
1/2 cup (50 g) grated Parmesan
Freshly grated melts smoothly; pre-shredded can turn grainy. Pecorino is a sharper, saltier stand-in.
2 scallions, sliced, plus hot sauce for serving
Fresh parsley or chives work too. Serve hot sauce on the side so everyone controls their own heat.
Tips & Tricks
Don't crowd the shrimp
Cook them in a single layer in a hot pan so they sear instead of steam. Overcrowding is the number one reason shrimp turn rubbery.
Watch the garlic
Add it after the peppers have softened and stir constantly for 30 seconds. Burnt garlic turns the whole sauce bitter.
Save your pasta water
A splash of starchy water loosens a tight sauce and helps it cling. Scoop a cup out before you drain.
Season in stages
Taste after the broth goes in, then again at the end. Cajun blends vary wildly in salt, so adjust at the finish.
Pro Tips
Step-by-Step Instructions
1. Boil the pasta
Bring a large pot of salted water to a rolling boil and cook the pasta 1 minute shy of the package directions. Scoop out 1 cup of pasta water, then drain. The pasta should still have a firm bite in the center.
2. Sear the sausage
Heat the olive oil in a large deep skillet over medium-high heat (375°F / 190°C) for 2 minutes. Add the sausage rounds and cook 5 to 6 minutes, stirring occasionally, until deeply golden brown on the edges and lightly crisp.
3. Soften the vegetables
Lower the heat to medium (350°F / 175°C) and add the onion and bell pepper to the sausage drippings. Cook 5 minutes, stirring, until the onion is translucent and the peppers are tender but still hold their shape.
4. Bloom the spices
Stir in the garlic and Cajun seasoning and cook 30 seconds, until the garlic smells nutty and the spices coat the vegetables. Pour in the chicken broth and scrape up any browned bits from the bottom of the pan.
5. Cook the shrimp
Nestle the shrimp into the pan in a single layer and cook 3 to 4 minutes per side at a gentle simmer (about 200°F / 93°C in the liquid) until they curl into a loose C shape and turn opaque pink. A C shape means tender; a tight O means overcooked.
6. Build the sauce
Reduce the heat to low (300°F / 150°C), pour in the half-and-half, and stir gently for 3 to 4 minutes until the sauce thickens enough to coat the back of a spoon. Do not let it boil or it may separate.
7. Toss and finish
Add the drained pasta and Parmesan and toss for 1 to 2 minutes until every noodle is glossy and coated, loosening with splashes of pasta water as needed. Taste and adjust the Cajun seasoning and salt.
8. Serve hot
Scatter the scallions over the top and serve right away with hot sauce on the side. The pasta is best the moment the sauce is silky and the shrimp are still plump.
Delicious Variations
Creamy Cajun Chicken Pasta
Swap the shrimp for 1 pound of sliced chicken breast, searing it 6 minutes before adding the vegetables.
Spicy Andouille Version
Use full-fat andouille sausage and add 1/2 teaspoon cayenne with the Cajun seasoning for a bolder kick.
Dairy-Free Coconut Cajun Pasta
Replace the half-and-half with full-fat coconut milk and skip the Parmesan; add 1 teaspoon lemon juice to brighten it.
How to Store Cajun Shrimp and Sausage Pasta – Skinny Spatula
Refrigerator
Store leftovers in an airtight container in the fridge for up to 3 days. Keep the sauce and pasta together; it thickens as it chills.
Freezer
Freezing is not ideal because the shrimp turn rubbery and the cream sauce can separate, but you can freeze it up to 1 month if needed. Thaw overnight in the fridge.
Reheating
Reheat gently in a covered skillet over low heat with a splash of broth or water, stirring until loosened, about 5 minutes. Avoid the microwave on high, which toughens shrimp.
Frequently Asked Questions
Q: Can I use frozen shrimp for Cajun shrimp and sausage pasta?
Yes, frozen shrimp work perfectly as long as you thaw them fully and pat them dry first. Thaw overnight in the fridge or under cold running water for 10 minutes, then blot with paper towels so they sear instead of steam.
Q: How do I keep the cream sauce from curdling?
Keep the heat low after the half-and-half goes in and never let the sauce come to a full boil. Stir gently and add the dairy at the end, off a hard boil, so the proteins stay smooth.
Q: Is this Cajun shrimp and sausage pasta spicy?
It has a warm, smoky kick rather than a burning heat, depending on your Cajun blend. Use a mild blend and pass hot sauce at the table so everyone can dial in their own spice level.
Q: What pasta shape is best for this recipe?
Penne and rigatoni are the best choices because their ridges and hollow centers trap the creamy sauce. Fusilli and farfalle are good backups if your pantry is running low.
Q: Can I make this recipe dairy-free?
Yes, swap the half-and-half for full-fat canned coconut milk and leave out the Parmesan. Add a squeeze of lemon juice at the end to replace the salty tang the cheese provides.
