Preheat and Prep
Preheat your oven to 400°F (200°C). Line a baking sheet with parchment paper or foil for easy cleanup.
Season the Salmon
Place the salmon fillets on the prepared baking sheet. Drizzle with olive oil and season with salt, pepper, and any optional spices. Lay lemon slices over each fillet.
Bake the Salmon
Bake for 12–15 minutes, depending on thickness, or until the salmon flakes easily with a fork and reaches an internal temp of 145°F.
Make the Dill Sauce
While the salmon bakes, whisk together sour cream, mayonnaise, lemon juice, dill, garlic, salt, and pepper in a small bowl. Adjust seasoning to taste.
Serve
Plate the salmon and spoon dill sauce over each fillet. Garnish with extra dill or lemon wedges, if desired.
