This is the salmon recipe I make when I want something that feels intentional without requiring much attention from me at all. Low oven, simple topping, set a timer — that’s basically the whole deal.
Slow-roasting is the secret here. Cooking the salmon gently keeps it incredibly tender and forgiving, especially if you’re serving a crowd or cooking while doing ten other things. The Dijon, garlic, parsley, and olive oil form a loose paste that perfumes the fish as it cooks, but doesn’t overwhelm it. You end up with salmon that’s moist all the way through, flakes easily, and looks great straight out of the oven.
It works just as well for a dinner party centerpiece as it does for a weeknight meal, which is why I come back to it so often. The hardest part is chopping parsley — and even that doesn’t need to be perfect. If it’s a little rustic, no one’s mad about it.
Slow-Roasted Dijon Salmon
Ingredients
- 1 3-pound salmon fillet, skin on
- 4 garlic cloves grated
- ¼ cup fresh parsley minced
- 1 tablespoon Dijon mustard
- ½ teaspoon kosher salt
- 2 tablespoons olive oil
Instructions
- Preheat the oven to 325°F. Line a baking sheet with parchment paper.
- Place the salmon on the prepared baking sheet, skin side down.
- In a small bowl, stir together the garlic, parsley, Dijon mustard, salt, and olive oil until you have a thick, spreadable paste.
- Spread the mixture evenly over the surface of the salmon.
- Roast for about 20 minutes, until the salmon flakes easily with a fork but is still tender and moist in the center.
- Serve warm, finishing with extra parsley if you like.
Notes
Notes
- This method is very forgiving. If the salmon stays in the oven an extra few minutes, it will still be tender.
- For smaller households, the recipe scales down easily — just keep the oven temperature the same.
- Leftovers are excellent flaked into salads or grain bowls.
