01 - Season scallops generously with kosher salt and freshly ground black pepper on both sides, ensuring even coverage for optimal flavor penetration.
02 - Heat olive oil and 1 tablespoon butter in a large skillet over medium-high heat until shimmering. Arrange scallops in a single layer without crowding. Sear for 2–3 minutes per side until golden-brown crust forms and centers turn opaque. Transfer to plate and tent with foil.
03 - Reduce heat to medium. Add remaining 1 tablespoon butter to skillet. Sauté minced garlic and diced shallot for 1–2 minutes until fragrant and translucent, being careful not to brown the garlic.
04 - Stir in Cajun seasoning, smoked paprika, and cayenne pepper. Cook for 30 seconds to release essential oils and intensify flavors, stirring constantly to prevent burning.
05 - Pour in heavy cream and stock while scraping up browned fond from pan bottom with a wooden spoon. Simmer for 2–3 minutes until sauce coats back of spoon and reduces slightly.
06 - Add grated Parmesan and lemon juice, stirring until cheese completely melts and sauce becomes velvety smooth. Adjust seasoning with salt and pepper as needed.
07 - Return seared scallops to pan, turning to coat in sauce. Warm through for 1 minute. Remove from heat, garnish with fresh parsley, and serve immediately with sauce spooned over scallops.
