This dish combines tender shrimp with colorful bell peppers and silky pasta all enveloped in a rich, spiced Cajun cream sauce. The sauce melts Parmesan cheese and simmered cream with fragrant spices, providing a luscious coating to the linguine or fettuccine. Quick sautéing of shrimp and vegetables delivers texture and bright flavors. Garnish with fresh parsley and lemon wedges for a fresh finish. Perfect for a satisfying and flavorful dinner that comes together effortlessly in under 40 minutes.

The moment I sprinkled that first batch of Cajun seasoning over raw shrimp, the kitchen filled with this incredible smoky aroma that made me realize this was going to be something special. I'd been craving something with a little kick after a long gray week of comfort food, and the vibrant red peppers against that creamy sauce looked like pure happiness on a plate.

My sister was over that night, skeptical about the spice level, but ended up going back for seconds and literally scraping the sauce from the pan with her fork. Now she requests it every time she visits, and I've learned to always keep an extra lemon on hand because she loves that bright hit of acidity at the end.

Ingredients

  • Large shrimp: I've learned to pat them completely dry before seasoning, which helps them develop a gorgeous sear instead of steaming in the pan
  • Fettuccine or linguine: These flat noodles catch the sauce beautifully, though I've used penne in a pinch and it still works wonderfully
  • Red and yellow bell peppers: The sweetness they add when sautéed balances all that spice, so don't skip this step or substitute with something milder
  • Red onion: Thinly sliced so it softens into sweet strands throughout the dish
  • Heavy cream: Creates that velvety restaurant-style coating that clings to every strand of pasta
  • freshly grated Parmesan: Pre-grated just doesn't melt the same way, and you can really taste the difference
  • Cajun seasoning: I keep a small jar of my homemade blend, but Tony Chachere's works perfectly if you're buying it
  • Smoked paprika: Totally optional, but it adds this incredible depth that makes people ask what your secret ingredient is
  • Olive oil and butter: Using both gives you flavor from the butter while the oil prevents it from burning at higher heat

Instructions

Cook the pasta:
Get your salted water boiling and cook the noodles until they're just shy of done, since they'll finish in the sauce later
Season the shrimp:
Pat those shrimp completely dry with paper towels, then toss them with a tablespoon of the Cajun seasoning, salt, and pepper until they're evenly coated
Sear the shrimp:
Heat half your oil and butter in a large skillet over medium-high heat, then cook the shrimp for about 2-3 minutes per side until they turn pink and opaque
Sauté the vegetables:
In the same pan (don't wash it, that flavor is gold), cook your onion and peppers for 4-5 minutes until they start to soften, then add the garlic for just one minute so it doesn't burn
Build the sauce:
Lower the heat and stir in your remaining spices, then pour in the cream and let everything come to a gentle bubble
Finish it:
Melt in the Parmesan until the sauce is silky smooth, then toss in your pasta and shrimp and let it all get friendly together for a couple minutes

This recipe became my go-to for celebrating small victories, like finishing a big project or just surviving a particularly chaotic Monday. There's something about the combination of slurping pasta and savoring those perfectly spiced shrimp that makes any dinner feel like a proper occasion.

Making It Your Own

I've discovered that half-and-half works if you're watching your intake, though the sauce won't be quite as luxurious. Sometimes I throw in a handful of spinach at the very end because it wilts beautifully into all that creamy goodness and makes me feel slightly virtuous.

Perfect Pairings

A crisp white wine cuts through the richness perfectly, though an ice-cold beer works just as well on hot summer nights. I love serving this with a simple green salad dressed with nothing but lemon juice and olive oil to let the pasta shine.

Getting Ahead

You can slice all your vegetables and mix your spice blend up to a day ahead, which makes weeknight cooking feel almost effortless. The shrimp are best cooked fresh, but you can clean and season them in the morning so they're ready to hit the hot pan.

  • Everything moves fast once you start cooking, so have your ingredients prepped and within reach
  • Warm plates make a surprising difference in keeping the sauce at the perfect consistency
  • That squeeze of fresh lemon right before serving is the bright note that pulls everything together

This is the kind of recipe that makes people pause between bites and ask for the recipe, and I love that moment every single time.

Recipe Questions

Use large, peeled, and deveined shrimp to ensure quick cooking and tender bites in the creamy sauce.

Yes, fettuccine or linguine work well, but other long pastas like spaghetti or bucatini can be used depending on preference.

The Cajun seasoning offers moderate heat, which can be adjusted by adding more red pepper flakes or omitting them for milder flavor.

Substitute half-and-half for heavy cream to reduce the richness while maintaining creaminess.

Fresh chopped parsley and lemon wedges add brightness and a fresh contrast to the creamy, spicy sauce.

It's best enjoyed freshly cooked, as the creamy sauce thickens upon reheating, but leftover pasta can be gently warmed with a splash of cream or water.
