Pat the shrimp dry with paper towels, then season generously with Cajun seasoning, salt, and pepper to enhance flavor and ensure a good sear.

Heat butter and olive oil in a wide skillet over medium-high heat. Arrange shrimp in a single layer, cooking undisturbed for 1-2 minutes per side until golden crust forms and centers are opaque. Remove shrimp and set aside on a plate.

If skillet is dry, add a small amount of butter. Add minced garlic and sauté gently for about 30 seconds until fragrant, avoiding browning to prevent bitterness.

Reduce heat to medium-low and slowly pour in heavy cream, scraping up browned bits from the pan for depth of flavor. Simmer gently for 3-4 minutes until sauce thickens slightly.

Add grated Parmesan cheese gradually, stirring continuously until fully melted and the sauce is smooth and creamy, coating the back of a spoon.

Bring salted water to a boil in a separate pot. Cook rotini until just al dente, then drain, reserving a splash of pasta water to adjust sauce consistency if necessary.

Add cooked pasta to the sauce, stirring to coat evenly. Gently fold in the seared shrimp, taking care not to break their texture. Serve immediately with extra Parmesan and optional fresh parsley garnish.
