First Step: Preheat your oven to 275°F (135°C) and line a baking sheet with parchment paper or foil for easy cleanup.

Second Step: Pat the salmon fillets dry using paper towels to ensure proper browning and brush both sides lightly with olive oil.

Third Step: Season the salmon evenly with sea salt, black pepper, and minced garlic, then place lemon slices on top.

Fourth Step: Arrange the fillets on the prepared baking sheet with some space between each, alongside the roasted potatoes.

Fifth Step: Return the pan to the oven and slow roast for 15 to 18 minutes for medium rare or up to 25 minutes for medium, based on thickness.

Sixth Step: Check doneness by seeing if the salmon flakes easily with a fork or reaches an internal temperature of 125°F (52°C), then finish by squeezing fresh lemon juice from one lemon over the salmon.

Final Step: Remove from oven and let rest for 5 minutes before serving. This approach keeps everything juicy and flavorful, perfect for pairing with roasted veggies. For more fish recipes, try our favorite on air fryer salmon bites, which offers another easy way to cook fish quickly.
