Follow these straightforward steps to create Blackened Salmon Stuffed with Spinach & Parmesan effortlessly:

1. Preheat the Oven: Preheat your oven to 375°F (190°C) to prepare for baking the salmon.
2. Prepare the Filling: In a large mixing bowl, combine chopped spinach, Parmesan cheese, cream cheese, minced garlic, onion powder, and black pepper. Mix well until combined.
3. Prepare the Salmon: Place the salmon fillets skin-side down on a cutting board. Using a sharp knife, carefully cut a pocket into each fillet, making sure not to cut through.
4. Stuff the Salmon: Generously fill each salmon pocket with the spinach and cheese mixture. Secure the openings with toothpicks if needed.
5. Season the Salmon: In a small bowl, mix paprika, cayenne pepper, thyme, salt, and black pepper. Rub this seasoning blend all over the top and sides of each salmon fillet.
6. Sear the Salmon: Heat the olive oil in an oven-safe skillet over medium-high heat. Add the stuffed salmon fillets to the skillet, cooking for 3-4 minutes until a crust forms on the bottom.
7. Bake the Salmon: Gently flip the salmon fillets, then transfer the skillet to the preheated oven. Bake for an additional 12-15 minutes, or until the salmon flakes easily with a fork.
8. Remove and Rest: Once cooked, remove the skillet from the oven and let the salmon rest for a few minutes before serving.
9. Plate the Dish: Carefully transfer the salmon to a serving platter, and garnish with lemon wedges for added brightness.
