The cajun shrimp and sausage pasta you’ll find here is a one-skillet dinner built for busy weeknights without sacrificing depth of flavor. It pairs sweet shrimp with smoky andouille, a creamy tomato-spiced sauce, and penne that soaks up every drop. You get a balanced plate of protein, starch, and vegetables in about half an hour.
This version keeps the seasoning honest: paprika, cayenne, garlic, and thyme do the work instead of a bottled mix with fillers. The shrimp stay tender because they cook last and only until opaque. The sausage renders its fat into the pan, which becomes the base for the sauce. Making this cajun shrimp and sausage pasta at home is surprisingly straightforward once you know the key steps.
If you like a garlic shrimp pasta but want more smoke and heat, this is the logical next step. It scales easily and reheats without turning gummy if you follow the storage steps below. The cajun shrimp and sausage pasta works well for weeknight cooking when time is limited.
Why You’ll Love These Cajun Shrimp And Sausage Pasta
- One pan means fewer dishes and a sauce that builds from the sausage drippings.
- Shrimp cook in under 4 minutes, so the protein never goes rubbery from overcooking.
- The cream-tomato base cools the cayenne just enough for people who fear heat.
- Penne holds the sauce better than long noodles, so each bite stays coated.
- Leftovers keep their texture better than most cream pastas when reheated gently.
Ingredients You’ll Need
- 12 oz penne pasta – use bronze-cut if you can; the rough surface grabs sauce.
- 1 lb large shrimp, peeled and deveined – 21/25 count gives a meaty bite.
- 12 oz andouille sausage, sliced into 1/4-inch rounds – smoky, not sweet.
- 2 tbsp olive oil – splits the difference with sausage fat for even browning.
- 1 medium yellow onion, diced – about 1 cup, for sweetness under the spice.
- 1 red bell pepper, diced – adds color and a mild counter to cayenne.
- 4 cloves garlic, minced – fresh only; powder turns the sauce flat.
- 2 tbsp cajun seasoning – low-sodium so you control the salt.
- 1 tsp smoked paprika – reinforces the sausage’s wood-smoke note.
- 1/2 tsp cayenne – adjust down to 1/4 if your seasoning is already hot.
- 1 cup crushed tomatoes – thick, not watery, to keep the sauce from breaking.
- 1 cup heavy cream – the fat keeps the tomato acid from curdling.
- 1/2 cup chicken broth – loosens the sauce for tossing the pasta.
- 1/2 cup grated parmesan – fine grate melts faster than a wedge.
- 2 tbsp parsley, chopped – finishes with a clean, herbal note.
Ingredient Substitutions
Andouille sausage: Replace with an equal weight of smoked kielbasa if andouille is unavailable. Kielbasa is milder and slightly sweeter, so add 1/2 tsp extra smoked paprika to recover the smoke. Expect less spicy bite and a softer crust on the slices since kielbasa has lower fat content.
Heavy cream: Use 1 cup of half-and-half for a lighter sauce, but keep the heat at medium-low when adding it. Half-and-half curdles faster than cream because of lower fat, so whisk constantly and don’t let it boil. The result is thinner and a touch less rich but still coats the pasta.
Crushed tomatoes: Swap for 1 cup of tomato passata if you want a smoother sauce with no pulp. Passata reduces faster, so cut the broth to 1/4 cup or the dish turns soupy. The color stays brighter and the texture reads more like a velouté than a rustic sauce.
Penne pasta: Use 12 oz of rotini if penne is gone; the spirals trap more sauce per bite. Rotini cooks 1 minute faster than penne at the same boil, so start checking at 8 minutes. The swap changes nothing in flavor but improves sauce adherence for kids who swipe the bowl.
Red bell pepper: Replace with 1 diced zucchini for a lower-carb version that still adds moisture. Zucchini releases water, so sauté it 2 minutes longer to drive off liquid before adding tomatoes. The pepper’s sweetness disappears, leaving a more savory, green edge to the dish. If you enjoyed this, our lemon garlic shrimp is worth trying next.
Step-by-Step Instructions
- Bring 4 quarts of salted water to a boil and cook 12 oz penne until al dente, about 10 minutes. Drain, reserving 1/2 cup of the starchy water, and set the pasta aside.
- Set a 12-inch skillet on medium heat and add 2 tbsp olive oil. Lay in the sliced andouille in a single layer and brown both sides until golden and crispy, about 4 minutes per side, then remove to a plate.
- Lower the skillet to medium-low heat and add the diced onion and red bell pepper. Cook, stirring, until the onion turns translucent and the pepper softens, about 5 minutes.
- Stir in 4 cloves minced garlic, 2 tbsp cajun seasoning, 1 tsp smoked paprika, and 1/2 tsp cayenne. Toast the spices for 30 seconds until fragrant but not browned.
- Pour in 1 cup crushed tomatoes, 1 cup heavy cream, and 1/2 cup chicken broth. Raise to medium heat and simmer until the sauce thickens enough to coat a spoon, about 6 minutes.
- Add 1 lb shrimp to the sauce in a single layer and cook 2 minutes per side until pink and opaque. Overcooking past this point tightens the flesh, so pull them at the first sign of firmness.
- Return the sausage and add the drained penne, tossing to coat. Splash in reserved pasta water a tablespoon at a time if the sauce is tight.
- Off the heat, stir in 1/2 cup parmesan and 2 tbsp parsley. Serve immediately while the sauce is loose and glossy.
Pro Tips
Pat the shrimp dry before they hit the sauce so they sear instead of steaming, which keeps the pan sauce technique clean. Moisture on the surface lowers the pan temperature and leaches a gray film into the cream.
Slice the andouille uniformly so every round renders at the same rate; ragged pieces leave some chewy and some burnt. A 1/4-inch thickness is the sweet spot for browning without drying the center.
Reserve pasta water even if you think the sauce is loose; the starch rebinds a broken cream sauce in seconds. Add it off heat while tossing to avoid thinning the tomato base too early.
Buy shrimp already peeled if your evening is tight, but check for the vein; missed veins taste of grit against the smooth sauce. Frozen works if thawed in cold water for 10 minutes and dried well.
Taste the sauce before the shrimp go in and adjust cayenne there, not after, since seafood absorbs heat fast. A pinch of sugar cuts the tomato acid if your brand runs sharp.
Common Mistakes to Avoid
Crowding the skillet with sausage traps steam and prevents browning, leaving pale, rubbery rounds. Cook in two batches if your pan is under 12 inches or the slices overlap.
Adding cream to a hard boil makes it split into greasy flecks that no stirring fixes. Keep the simmer gentle after the dairy enters, and lower the heat the moment you see a bubble ring at the edge.
Overcooking the penne to soft before the sauce is ready means it turns to mush when tossed, since it keeps absorbing liquid. Pull it at al dente and let the sauce finish the softening.
Skipping the parsley reads as a small omission but the herb’s brightness is what keeps the rich dish from feeling heavy. Even a tablespoon changes the finish on the tongue. For another easy option, check out our pasta alla vodka.
Serving Suggestions
Plate the pasta in shallow bowls so the sauce pools rather than sliding off, and add a lemon wedge for those who want a sharp squeeze. A side of sausage and peppers stretches the meal if you’re feeding more than four.
A crisp green salad with oil and vinegar cuts the cream, and warm French bread mops the bowl. For wine, a cold pilsner or unoaked white handles the cayenne better than a heavy red.
If you want a seafood-forward starter, shrimp tapas share the lemon-and-pork theme without repeating the pasta.
Storage and Reheating
Cool the pasta to room temperature within 2 hours, then refrigerate in an airtight container for up to 3 days. Shrimp and cream both degrade past that window, so don’t push it to a fifth day.
Reheat in a skillet on medium-low heat with a splash of broth, stirring until the shrimp reach 145°F internally. The microwave works but heats unevenly and toughens the seafood, so cover and use 50% power in 30-second bursts.
The dish freezes poorly because the cream separates on thaw, leaving a grainy coat on the penne. If you must freeze, do it before adding cream and shrimp, then finish those fresh. You might also like our pasta celery.
Recipe Variations
Low-Carb Option
Replace the 12 oz penne with 14 oz of zucchini noodles and skip the pasta water step. Add the zoodles at the very end, tossing just 1 minute so they stay crisp, and expect a lighter sauce that clings less but keeps the cajun shrimp and sausage pasta flavor profile intact.
Extra Smoky Version
Swap the olive oil for 1 tbsp bacon fat and use a double-smoked andouille if you can find it. The smoke carries through the cream and pairs with the paprika for a backyard-grill note, though the salt rises so cut the seasoning’s added salt by half.
Cheesy Bake
After step 7, transfer to a 9×13 dish, top with 1 cup shredded cheddar, and broil 3 minutes until bubbly. The crust adds texture but the shrimp finish cooking in the oven, so pull them at the opaque stage before baking to avoid toughness.
Tomato-Free Version
Drop the crushed tomatoes and raise the cream to 1 1/2 cups with an extra 1/4 cup broth for body. You lose the red color and tang but gain a pale, peppery sauce that reads closer to a cajun shrimp and sausage pasta alfredo, best with a pinch more cayenne.
Cajun Shrimp And Sausage Pasta
Description
A smoky andouille sausage and tender shrimp tossed with penne in a creamy tomato-spiced sauce, all made in one skillet for easy cleanup. This balanced, flavor-forward dinner comes together in about half an hour with honest Cajun seasoning rather than bottled mixes.
Ingredients
Instructions
-
Boil the penne
Bring 4 quarts of salted water to a rolling boil in a large pot over high heat and cook 12 oz penne until al dente, about 10 minutes. Drain the pasta, reserving 1/2 cup of the starchy water, and set the pasta aside off the heat until the sauce is ready.
-
Brown the andouille
Set a 12-inch skillet on medium heat and add 2 tbsp olive oil to coat the surface. Lay in the sliced andouille in a single layer and brown both sides until golden and crispy, about 4 minutes per side, then remove the sausage to a plate and leave the rendered fat in the pan.
-
Soften vegetables
Lower the skillet to medium-low heat and add the diced onion and red bell pepper. Cook, stirring often, until the onion turns translucent and the pepper softens, about 5 minutes, building the sweet base under the spice.
-
Toast the spices
Stir in 4 cloves minced garlic, 2 tbsp cajun seasoning, 1 tsp smoked paprika, and 1/2 tsp cayenne with the softened vegetables. Toast the spices for 30 seconds until fragrant but not browned, stirring constantly so the garlic does not scorch.
-
Simmer the sauce
Pour in 1 cup crushed tomatoes, 1 cup heavy cream, and 1/2 cup chicken broth and raise the heat to medium. Simmer until the sauce thickens enough to coat a spoon, about 6 minutes, keeping the bubble gentle so the cream does not split.
-
Cook the shrimp
Add 1 lb shrimp to the sauce in a single layer and cook 2 minutes per side until pink and opaque and the internal temperature reaches 63°C (145°F). Overcooking past this point tightens the flesh, so pull them at the first sign of firmness for tender seafood.
-
Toss pasta and sausage
Return the browned sausage to the skillet and add the drained penne, tossing to coat every piece in the sauce. Splash in reserved pasta water a tablespoon at a time if the sauce is tight and needs loosening for even coverage.
-
Finish and serve
Off the heat, stir in 1/2 cup parmesan and 2 tbsp parsley until melted and distributed. Serve immediately while the sauce is loose and glossy for the best texture and flavor.
