01 - Preheat your oven to 400°F (200°C). Line a baking tray with parchment paper for effortless cleanup.
02 - Gently pat the salmon fillets dry with paper towels to ensure a crispy exterior. Arrange them neatly on the prepared baking tray.
03 - Drizzle olive oil evenly over each fillet. Season generously with sea salt and freshly ground black pepper. Top each salmon portion with a thin lemon slice.
04 - Bake the salmon in the preheated oven for 15 to 18 minutes, or until the fish flakes easily with a fork and is cooked through to your desired doneness.
05 - While the salmon bakes, prepare the dill sauce. In a medium bowl, whisk together the sour cream, mayonnaise, fresh lemon juice, finely chopped fresh dill, Dijon mustard, and garlic powder until thoroughly combined and smooth. Season the sauce with salt and freshly ground black pepper to taste.
06 - Remove the perfectly baked salmon from the oven. Serve each fillet immediately, accompanied by a generous dollop of the creamy dill sauce, either directly on top or alongside.
