I wanted something with real flavor on a random Thursday, and this is what I landed on.
Blackened shrimp, a creamy Cajun-spiced sauce, and pasta that soaks up every bit of it. It comes together in about 25 minutes, but it tastes like it took a lot more planning than that.
Why This Recipe Works
Coating the shrimp in Cajun seasoning before searing gives them a deeply flavorful crust that carries through the entire dish, not just the surface.
Building the sauce right in the same skillet used for the shrimp means you’re capturing all that leftover flavor instead of leaving it behind in the pan. 🌶️
A splash of cream mellows out the heat just enough, so the dish feels bold and spicy without overwhelming everything else on the plate.
What You’ll Need
| Ingredient | Amount |
|---|---|
| Large shrimp, peeled and deveined | 1 lb |
| Cajun seasoning | 2 tbsp, divided |
| Olive oil | 2 tbsp |
| Unsalted butter | 2 tbsp |
| Garlic, minced | 4 cloves |
| Bell pepper, sliced | 1 |
| Chicken broth | 1/2 cup |
| Heavy cream | 1 cup |
| Grated parmesan cheese | 1/2 cup |
| Penne or fettuccine pasta | 12 oz |
| Green onions, sliced | for topping |
Adjust the amount of Cajun seasoning to your own heat tolerance, some blends run spicier than others.
Tools You’ll Need
- Large deep skillet
- Pot, for cooking the pasta
- Tongs
- Wooden spoon
- Measuring cups and spoons
Pro Tips
1. Pat the shrimp dry before seasoning. Excess moisture prevents a good sear, and a good sear is where a lot of this dish’s flavor comes from.
2. Don’t overcook the shrimp. They only need 2 to 3 minutes per side. Overcooked shrimp turn rubbery fast, so pull them as soon as they turn pink and opaque.
3. Use the same skillet for the sauce. All those browned bits left behind from searing the shrimp add real depth once you start building the sauce.
4. Save some pasta water before draining. A splash helps loosen the sauce and helps it cling to the noodles if it thickens up too much.
5. Add the cheese gradually while stirring. This helps it melt smoothly into the sauce instead of clumping.
Substitutions and Variations
- Different protein: Chicken breast strips or andouille sausage both work well in place of shrimp.
- Spicier version: Add a pinch of cayenne on top of the Cajun seasoning, or a few dashes of hot sauce to the finished sauce.
- Milder version: Use a mild Cajun blend and reduce the amount slightly.
- Lower fat: Swap the heavy cream for half and half, though the sauce will be thinner.
- Extra vegetables: Add sliced mushrooms or a handful of spinach along with the bell pepper.
- Gluten-free: Use a gluten-free pasta, everything else in the dish is naturally gluten-free.
Make Ahead Tips
You can season the shrimp and slice the bell pepper up to a day ahead, storing both separately in the fridge.
I’d recommend cooking this dish fresh when you’re ready to eat, since shrimp and cream sauces are both best enjoyed shortly after cooking.
How to Make It
- Toss the shrimp with 1 tablespoon of Cajun seasoning until evenly coated.
- Heat the olive oil in a large skillet over medium-high heat. Sear the shrimp for 2 to 3 minutes per side, until pink and opaque. Remove and set aside.
- In the same skillet, melt the butter. Add the garlic and bell pepper, cooking for 3 to 4 minutes, until the pepper softens slightly.
- Sprinkle in the remaining Cajun seasoning and stir to coat the vegetables.
- Pour in the chicken broth, scraping up any browned bits from the bottom of the pan.
- Add the heavy cream and simmer for 3 to 4 minutes, until slightly thickened.
- Stir in the parmesan cheese until melted and smooth.
- Meanwhile, cook the pasta according to package instructions. Reserve 1 cup of pasta water, then drain.
- Add the drained pasta and cooked shrimp to the skillet, tossing to coat, adding reserved pasta water as needed to loosen the sauce.
- Top with green onions before serving.

For a lighter version, use half and half instead of heavy cream and reduce the parmesan slightly.
What to Serve It With
- A simple green salad with a light vinaigrette
- Garlic bread for soaking up extra sauce
- A cold glass of iced tea to balance the heat
Leftovers and Storage
Store leftovers in an airtight container in the fridge for up to 2 days.
Reheat gently on the stovetop over low heat with a splash of cream or broth, since the sauce thickens considerably once chilled. Shrimp can turn rubbery if overheated, so warm it gently rather than on high heat.
This dish doesn’t freeze particularly well since both the cream sauce and shrimp change texture significantly once thawed.
FAQ
Is this dish very spicy?
It depends on the Cajun seasoning blend you use, some run hotter than others. Start with less and add more to taste if you’re unsure.
Can I use frozen shrimp?
Yes, just thaw them completely and pat them very dry before seasoning for the best sear.
Can I make this without cream?
The cream is what gives the sauce its signature richness, but you can substitute a lighter option like half and half if you prefer.
Why did my shrimp turn out rubbery?
This usually means they were overcooked. Shrimp only need a couple of minutes per side, and they continue cooking slightly even after being removed from heat.
Can I double this recipe?
Yes, just sear the shrimp in batches to avoid overcrowding the pan, which can cause them to steam instead of sear properly.
Wrapping Up
This dish has become my answer for when I want something with real flavor and a little heat, without spending my whole evening in the kitchen.
It’s bold, satisfying, and fast enough to make on a weeknight when you still want dinner to feel like an event.
If you make this, come back and tell me how spicy you went, or if you tried it with chicken instead. 🍤
I’d love to hear how yours turned out.
