When you need a weeknight dinner that feels like a massive treat, this rich, deeply flavorful pasta is the absolute perfect choice. It brings all the bold, smoky, and spicy flavors of a New Orleans kitchen right to your dining room table in under 30 minutes.
The culinary secret to this dish is building layers of flavor in a single skillet. By searing the spiced shrimp and caramelizing the smoked sausage first, you leave behind incredible browned bits in the pan (what chefs call the fond). When you add the heavy cream and chicken broth, those savory drippings melt right into the sauce, creating a restaurant-quality dish that is impossible to resist.
Because we are using a high-quality smoked beef or turkey sausage, you get all of that incredible, savory smokiness that pairs flawlessly with the plump, tender shrimp!

What You’ll Need
To get the most out of this recipe, make sure you have all your ingredients chopped, measured, and ready to go before you turn on the stove!
The Proteins
- 1 lb Large shrimp: Peeled and deveined. (If using frozen, thaw them completely and pat them very dry!).
- 6 oz Smoked beef sausage or smoked turkey sausage: Thinly sliced into rounds.
The Pasta & Veggies
- 10 oz Fettuccine pasta: Penne or linguine also work beautifully.
- ½ Yellow onion: Thinly sliced.
- 1 Red bell pepper: Thinly sliced.
- 2–3 cloves Garlic: Freshly chopped or minced.
The Creamy Cajun Sauce
- 2 tbsp Olive oil: Divided, for searing.
- 1 cup Chicken broth: Sodium-free is best so you can control the saltiness of the final dish.
- 1 cup Heavy cream: Essential for a thick, luxurious sauce. (Milk will be too thin!).
- ½ cup Crushed tomatoes: Adds a slight acidity to cut through the heavy cream.
- ⅔ cup Grated Parmesan cheese: Freshly grated from a block melts best.
The Spice Blend
- 5 tsp Cajun or Creole seasoning: Divided (1 tsp for the shrimp, 4 tsp for the sauce).
- 1 tsp Brown sugar: To balance the heat.
- ½ tsp Dried oregano: For an earthy depth.
- 1 tbsp Fresh parsley: Chopped, for garnish.
- Salt and Black pepper: To taste.
How to Make It (Step-by-Step)
Prep time: 15 minutes | Cook time: 15 minutes | Total time: 30 minutes | Yield: 4 Servings
Step 1: Boil the Pasta Bring a large pot of heavily salted water to a boil. Add your fettuccine and cook according to the package directions until al dente (firm to the bite). Drain the pasta and set it aside.
Step 2: Sear the Shrimp In a medium bowl, toss the shrimp with 1 teaspoon of the Cajun seasoning, the dried oregano, and a pinch of salt and black pepper until well coated. Heat 1 tablespoon of olive oil in a large skillet over medium-high heat. Add the shrimp in a single layer and cook for 2 minutes per side just until pink and opaque. Remove the shrimp to a plate and set aside. (Do not overcook them!)
Step 3: Caramelize the Sausage Drizzle a tiny bit more olive oil into the same skillet. Add your sliced beef or turkey sausage and cook for 4–5 minutes, stirring occasionally, until the edges are beautifully browned and caramelized. Remove the sausage to the plate with the shrimp.
Step 4: Sauté the Veggies Lower the heat to medium. Add the remaining olive oil to the skillet, followed by the sliced onion, red bell pepper, the remaining 4 teaspoons of Cajun seasoning, the brown sugar, and a generous pinch of salt. Sauté for about 5 minutes until the vegetables soften, using your wooden spoon to scrape up all those delicious browned bits from the bottom of the pan. Toss in the chopped garlic and cook for 30 seconds until fragrant.
Step 5: Simmer the Sauce Pour in the crushed tomatoes, chicken broth, and heavy cream. Bring the mixture to a gentle simmer, stirring constantly. Let it bubble and reduce slightly for 2–3 minutes so the flavors can marry.
Step 6: The Cheesy Finish Stir the grated Parmesan cheese into the bubbling sauce until it is completely melted and smooth.
Step 7: Toss and Serve Add your cooked fettuccine and the caramelized sausage directly into the skillet. Toss everything together for 2–3 minutes until the pasta is hot and evenly coated in the thick cream sauce. Taste the sauce and adjust the salt and pepper if needed. Finally, gently fold in the cooked shrimp. Serve immediately, garnished with fresh chopped parsley!
Expert Tips for Success
- Do Not Wash the Skillet: The brown residue left behind after searing the shrimp and sausage is pure, concentrated flavor. Let the broth and tomatoes lift that right off the bottom of the pan to flavor your sauce!
- Dry Your Shrimp: Before seasoning your shrimp, pat them completely dry with a paper towel. Wet shrimp will steam in the pan instead of getting that beautiful, flavorful sear on the outside.
- Control the Heat: Cajun seasoning blends vary wildly in their spice levels. If you are sensitive to heat, start with half the recommended amount in the sauce, taste it, and add more at the end if desired.
Variations and Substitutions
Want to customize your pasta night?
- The Low-Carb Swap: Skip the fettuccine and serve this rich, creamy meat and seafood mixture over a bed of roasted zucchini noodles or spaghetti squash.
- Extra Veggies: Toss in a handful of fresh baby spinach or some halved cherry tomatoes during the last two minutes of cooking to sneak some extra greens into your meal.
- Lighter Sauce: If you want to skip the heavy cream, use half-and-half instead. Just note that the sauce will be slightly thinner and you may need to let it simmer for an extra few minutes to reduce!
Serving Suggestions
Because this pasta is so rich and heavy, it needs simple, contrasting sides:
- The Sauce Soaker: You absolutely must serve this with warm, crusty French bread or garlic toast to mop up every last drop of the spicy cream sauce left on the plate.
- Keep it Fresh: Pair it with a simple, acidic side salad dressed with a sharp lemon vinaigrette to cut through the heavy cream and cheese.
Frequently Asked Questions (FAQs)
Can I make this dairy-free? It is tricky, but possible! You can swap the heavy cream for full-fat canned coconut milk (it will alter the flavor slightly, but pairs well with the Cajun spices) and use a dairy-free Parmesan alternative.
How do I store and reheat leftovers? Store any leftover pasta in an airtight container in the refrigerator for up to 3 days. Cream sauces tend to separate and become oily when microwaved on high heat. To reheat it perfectly, place it in a skillet over medium-low heat with a splash of chicken broth or milk, and toss gently until warmed through.
Can I freeze this pasta? I highly advise against freezing this dish. Heavy cream and Parmesan cheese will separate, curdle, and become incredibly grainy when frozen and thawed, completely ruining the luxurious texture of your sauce.
