Why This Recipe Works
I have tested dozens of creamy pasta recipes, and this blackened shrimp cavatappi stands out because it balances heat, richness, and texture perfectly. The blackened seasoning creates a crisp crust on the shrimp that stays juicy inside. The sauce comes together in the same pan, picking up the browned bits for deep flavor.
Using cavatappi noodles means every spiral captures the creamy sauce. Sweet corn adds bursts of sweetness that cool the spice. This method requires only one skillet and a pot for pasta, so cleanup is quick. You get a restaurant-quality meal without spending hours in the kitchen.
Another reason I love this recipe is its reliability. The shrimp cook in under six minutes, and the sauce thickens without curdling. By adding the corn and parmesan off heat, the sauce stays silky. This dish has become my go-to for busy weeknights when I crave something indulgent yet simple.

Ingredients
Ingredients
| Ingredient | Quantity | Notes |
|---|---|---|
| Cavatappi noodles | 8 ounces | Cook al dente; substitute with penne or fusilli |

| Blackened seasoning | 2 tablespoons | Store-bought or homemade (see our Cajun seasoning blend) |
| Unsalted butter | 1 tablespoon | Salted can be used; reduce added salt |
| Heavy cream | 1 cup (238 g) | For richness; half-and-half yields thinner sauce |
| Tomato paste | 2 tablespoons | Concentrates the tomato flavor |
| Sour cream | 1/4 cup (57.5 g) | Adds tang and prevents curdling |
| Parmesan cheese, grated | 1/2 cup (50 g) | Use freshly grated for best melt |

Step-by-Step Instructions
Cook the Pasta
- Bring a large pot of salted water to a rolling boil.
- Add 8 ounces cavatappi noodles and cook al dente according to package directions (8–9 minutes).
- Reserve 1 cup of pasta water before draining.
- Drain the pasta and set aside.
Season and Sear the Shrimp
- Pat the shrimp dry with paper towels.
- Toss the shrimp with 2 tablespoons blackened seasoning until evenly coated.
- Melt 1 tablespoon butter in a large skillet over medium-high heat.
- Add the shrimp in a single layer and cook 4–6 minutes, flipping halfway through.
- Transfer cooked shrimp to a plate and set aside.
Build the Cream Sauce
- Reduce heat to medium and pour 1 cup heavy cream into the same skillet.
- Bring to a low simmer while scraping up the browned bits from the bottom.
- Reduce heat to low and stir in 2 tablespoons tomato paste, 1/4 cup sour cream, and 1/2 cup grated parmesan.
- Whisk continuously until the parmesan is fully melted and the sauce is smooth (about 2 minutes).
- Add the drained cavatappi, cooked shrimp, and 1 can drained corn to the skillet.
- Toss everything together until well coated. If too thick, add a splash of reserved pasta water.
- Garnish with chopped green onion and serve immediately.

Chef Tips for Perfect Results
- Use raw, tail-off shrimp for easier eating. If using tail-on, remove after cooking.
- Do not overcrowd the pan when searing shrimp; cook in batches if necessary. Overcrowding causes steaming instead of blackening.
- Scrape up the browned bits (fond) thoroughly when adding cream—they hold intense flavor from the seasoning and butter.
- Serve the pasta immediately after tossing, as the sauce thickens as it cools. If reheating leftovers, add a splash of cream or milk to loosen.
- For extra heat, add a pinch of cayenne to the blackened seasoning or a drizzle of hot sauce before serving.
id=”common-mistakes-to-avoid”
Common Mistakes to Avoid
- Overcooking the shrimp. Shrimp turn rubbery when cooked too long. Why? They continue to cook in the residual heat. Fix: sear for only 2–3 minutes per side and remove immediately.
- Using pre-grated parmesan. It contains anti-caking agents that prevent smooth melting. Fix: grate fresh parmesan from a block.
- Adding cold sour cream directly. It can curdle when hitting hot cream. Fix: bring sour cream to room temperature or temper it by stirring in a few tablespoons of the hot sauce first.
- Not reserving pasta water. The starchy water helps thin the sauce without breaking it. Fix: always reserve 1 cup before draining.
- Skipping the fond deglazing. Those browned bits are concentrated flavor. Fix: always scrape the pan while adding cream.

Variations and Substitutions
| Ingredient | Substitution | Impact on Flavor |
|---|---|---|
| Heavy cream | Full-fat coconut milk | Adds slight coconut sweetness; dairy-free |
| Parmesan | Pecorino Romano | Saltier, sharper flavor |
| Sour cream | Greek yogurt (full-fat) | Tangier; may separate slightly if overheated |
| Blackened seasoning | Cajun seasoning + extra paprika | Less heat; still smoky |
| Corn | Chopped bell peppers (red/yellow) | Adds crunch and sweetness |
| Cavatappi | Penne, fusilli, or ziti | Similar hold for sauce; cook time varies |

Serving Suggestions and Pairings
Serve blackened shrimp cavatappi with a crisp green salad dressed in lemon vinaigrette to balance the creamy sauce. Garlic bread or crusty baguette slices are perfect for soaking up every last drop. For a non-alcoholic beverage, iced tea with mint or a sparkling lemonade complements the spice without overpowering it.
This dish shines at casual dinner parties or Sunday suppers. Pair it with roasted asparagus or steamed broccoli for added vegetables. For a lighter lunch, reduce the portion size and serve with a side of coleslaw.

id=”frequently-asked-questions”
Frequently Asked Questions
Can I use frozen shrimp?
Yes, thaw completely under cold running water and pat dry before seasoning. Excess moisture prevents proper blackening.
What if I don’t have blackened seasoning?
Combine 1 tablespoon paprika, 1 teaspoon each garlic powder, onion powder, dried thyme, and oregano, plus 1/2 teaspoon cayenne and salt. That substitutes the 2 tablespoons.
How can I tell when the shrimp are done?
The shrimp turn pink and form a light crust; the thickest part registers 120°F. They curl into a loose C shape—tight O means overcooked.
Can I make this dish ahead?
Cook the pasta and shrimp separately, then combine with the sauce just before serving. The sauce can be made 1 day ahead and refrigerated.
What can I serve with this pasta for a crowd?
Double the recipe and serve with a Caesar salad and cheesy garlic bread. Cornbread also pairs well with the Cajun flavors.
