½ pound (225 g) smoked sausage, sliced – Adds smoky, savory flavor and crispy edges.

For the Vegetables

1 large shallot, finely diced – Provides a mild, sweet onion flavor.
1 medium red bell pepper, sliced – Adds sweetness, color, and texture.
2 large garlic cloves, finely chopped – Brings aromatic depth to the sauce.

For the Cajun Cream Sauce

2 tablespoons Cajun seasoning – Delivers bold, smoky spice.
2 tablespoons tomato paste – Adds richness and depth.
1½ cups low-sodium chicken stock – Forms the flavorful base of the sauce.
1 cup half-and-half – Creates a creamy, silky texture.
¼ cup grated Parmesan cheese – Adds salty, nutty richness.

For Finishing

Fresh parsley, roughly chopped – Adds freshness and color.
Salt and freshly ground black pepper, to taste – Adjust seasoning before serving.

Step-by-Step Instructions

Step 1: Cook the Pasta

Bring a large pot of generously salted water to a boil.

Cook the pasta according to the package directions until al dente.

Before draining, reserve 1–2 cups of the pasta water.

Drain the pasta and set it aside.

Step 2: Cook the Shrimp

Heat the olive oil in a large deep skillet over medium heat.

Add the shrimp in a single layer.

Cook for 3–4 minutes, turning halfway through, until they are pink and opaque.

Transfer the shrimp to a plate.

Step 3: Brown the Sausage

Using the same skillet, add the sliced smoked sausage.

Cook for 2–3 minutes, allowing the edges to become lightly browned and crispy.

Remove the sausage and set aside with the shrimp.

Step 4: Sauté the Vegetables

Add the diced shallot and sliced red bell pepper to the same pan.

Cook for 1–2 minutes, stirring occasionally.

Add the garlic and cook for another minute until fragrant.

Step 5: Build the Sauce

Sprinkle the Cajun seasoning over the vegetables.

Stir in the tomato paste and cook for about 1 minute.

Pour in the chicken stock while scraping the bottom of the pan to release all the flavorful browned bits.

Step 6: Make It Creamy

Reduce the heat to low.

Stir in the half-and-half.

Allow the sauce to simmer gently for 2–3 minutes, stirring occasionally until slightly thickened.

Step 7: Return the Protein

Add the cooked shrimp and smoked sausage back into the skillet.

Stir gently until everything is coated in the creamy Cajun sauce.

Step 8: Add the Pasta

Transfer the cooked pasta to the skillet.

Toss everything together until the pasta is fully coated.

If the sauce seems too thick, stir in a splash of the reserved pasta water until it reaches your desired consistency.

Step 9: Finish and Serve

Stir in the grated Parmesan cheese until melted.

Add the chopped parsley.

Taste and adjust with salt and freshly ground black pepper if needed.

Serve immediately while hot.

Recipe Notes & Tips

Don’t Overcook the Shrimp – Remove them as soon as they turn pink to keep them tender.

Freshly Grated Parmesan Melts Better – Avoid pre-shredded cheese for the smoothest texture.
Control the Spice – Use less Cajun seasoning for a milder dish or add extra for more heat.
Brown the Sausage Well – Crispy edges add incredible flavor to the sauce.
Serve Immediately – The creamy sauce is at its best while freshly made.
