Recipe Directions for Slow Roasted Salmon

Cooking Slow Roasted Salmon is a straightforward process that delivers incredible results. Follow these steps, and you’ll have a dish that impresses everyone around the table!
- Preheat your oven to 275ºF. This low temperature is key for ensuring that the salmon cooks perfectly.
- Line a rimmed baking sheet with parchment paper. This will make cleanup a breeze!
- Remove the salmon from the refrigerator to take some of the chill off. This helps with even cooking.
- In a small bowl, combine the sour cream, 2 tablespoons of Dijon mustard, chopped dill, capers, the caper brine, salt, and black pepper. Stir until smooth.
- Zest half of the lemon into the bowl, then cut it in half and squeeze the juice from half into the mixture. This adds freshness and acidity!
- Mix everything together until well combined. The sauce should be thick but drizzle-able. If it’s too thick, add a small splash of water or a bit more lemon juice to thin it out.
- Place the salmon, skin side down, onto the lined baking sheet. Pat the top dry with a paper towel. This ensures the skin gets crispy.
- Spread a heaping spoonful (about 3 tablespoons) of the mustard sauce in a thin layer all over the salmon. Don’t be shy—this sauce is where a lot of flavor comes from!
- Roast the salmon in the oven until it is just barely cooked through, which should take about 35 to 50 minutes. You’ll know it’s ready when it flakes easily with a fork and has an internal temperature of 135ºF. Check consistently to avoid overcooking.
- Let the salmon rest for 5 minutes after removing it from the oven. This allows it to finish cooking and stay moist.
- Drizzle the remaining sauce over the salmon or serve it on the side. Garnish with extra sprigs of fresh dill before serving for that beautiful touch!
Things Worth Knowing
- Check for Doneness: Use an instant-read thermometer to check for an internal temperature of 135ºF. This ensures the salmon is perfectly cooked without being dry.
- Room Temperature: Allowing the salmon to come to room temperature before cooking helps it cook evenly. Avoid the fridge chill!
