Preheat oven to 375°F (190°C). Line a baking sheet with parchment paper.
Prepare salmon: Pat fillets dry and place them on the baking sheet. Season with salt, pepper, and paprika.
Make garlic butter sauce: In a small saucepan, melt butter over low heat. Add minced garlic, lemon juice, oregano, and thyme. Stir for 1 minute until fragrant.
Coat salmon: Brush the garlic butter mixture generously over each fillet.
Bake: Place in the oven for 12-15 minutes (or until salmon flakes easily with a fork).
Garnish: Top with fresh parsley and lemon slices before serving.
