Cook rice per package instructions and keep warm.
Pat salmon dry and season both sides with salt, pepper, and paprika. Heat 1 tablespoon olive oil in a skillet over medium heat. Sear skin-side down for 3–4 minutes without moving. Flip and cook for a further 3–4 minutes until cooked through. Remove and set aside.
In the same skillet, melt butter over medium heat. Add garlic and sauté for 30–60 seconds until fragrant.
Add shrimp and season with salt, pepper, paprika, and parsley. Cook 2–3 minutes per side until pink and just golden. Do not overcook.
Pour in the heavy cream, add onion powder and cayenne, and simmer for 3–4 minutes until slightly thickened. Stir in lemon juice and adjust seasoning. Return the salmon to the pan and spoon the sauce over it.
Plate rice, top with salmon, and ladle shrimp and sauce over everything. Garnish with parsley and a lemon wedge.
