Roasted Salmon with Vegetable Lentil Ragout and Mustard Horseradish Sauce is a fancy schmancy dish that makes your family feel like your most important guests! This is one of the best combinations you can even imagine and uses simple, easy to find ingredients.
Although it seems like there are a lot of steps and ingredients to make my Roasted Salmon with Vegetable Lentil Ragout and Mustard Horseradish Sauce. I’ll explain the steps in order so all you have to do is follow the directions. At the end, you will have a dish with so many delicious flavors no one will believe that you didn’t do a take out from the fanciest restaurant in town!
Make the lentil ragout by sauteeing onions, carrots, celery, and garlic with fresh thyme and rosemary. This brings out the flavor of the vegetables before combining them with the lentils. The lentils cook in wine and chicken stock or water (if you want to keep this vegetarian) for only 15 minutes.
While the lentils are cooking, make the sauce and saute and then roast the salmon. When the salmon is in the oven, toss the arugula garnish together with the lemony dressing. I soaked the thinly sliced red onion for the garnish in ice water for 10 minutes to eliminate some of the intensity. You can skip this step if you like raw onions.
The final Oven Roasted Salmon dish, when plated, is a work of art. It is as delicious as it is beautiful. Don’t these photos make you want to run out and buy a fresh piece of salmon for a weeknight dinner?

- 1/3 cup fresh thyme leaves chopped
- 1 tablespoon fresh rosemary finely chopped
- 2 bay leaves snapped in half
- 1 ½ cups red wine
- 2 ½ cups chicken stock or water
For the Salmon:
- 1 tablespoon olive oil
- 1 ½ pounds salmon cut into 4 pieces
- ¾ teaspoon fine sea salt
- freshly ground pepper
For the Sauce:
- 2 cups white wine
- 2 shallots finely chopped
- 5 sprigs thyme
- 2 bay leaves
- 1 ½ tablespoons cornstarch
- 1 ½ cups fat free half and half
- 3 tablespoons coarse Dijon mustard
- 1 ½ tablespoons horseradish
For the garnish:
- 2 cups baby arugula
- ½ small red onion very thinly sliced and soaked in ice water for 10 minutes
- 3 tablespoons olive oil
- 1 tablespoon lemon juice
- 1 tablespoon maple syrup
- 1 tablespoon whole grain Dijon mustard
Instructions
For the Lentil Ragout:
-
In a large, heavy saucepan, heat the olive oil over medium high heat. Saute the onions, carrots and celery for 2-3 minutes until they are starting to sizzle. Stir in the garlic and let cook for another two minutes, stirring constantly. Add all of the herbs and stir them around until they are fragrant, about another minute.
-
Add the wine and water and bring the lentils to a boil. Lower the heat to medium low and cook the lentils, covered, for 15 minutes. Do not overcook them.
-
While the lentils are cooking, make the sauce and oven roast the salmon.
-
Preheat the oven to 350 degrees.
For the sauce:
-
In a medium saucepan, bring the wine, shallots, thyme and bay leaves to a boil. Reduce the liquid by one-half. Strain the liquid into a one cup measuring cup and put the liquid back in the saucepan.
-
When the oven roasted salmon is done cooking, in a small bowl whisk the cornstarch and cold fat free half and half. Make sure to get all of the lumps out.
-
Heat the reduced wine mixture over medium heat until it simmers. Pour in the cornstarch mixture and whisk well until the sauce just starts to thicken. Remove from heat and whisk in the mustard and horseradish.
-
Keep the sauce warm over low heat.
For the salmon:
-
Dry the salmon filets well with paper towels. Sprinkle with salt and pepper.
-
In a medium ovenproof skillet, heat the olive oil over medium high heat. Add the salmon to the hot skillet and cook for 3-4 minutes until the filets are brown on the bottom.
-
Remove the pan from the heat and turn the salmon filets over. Place in the preheated oven and cook them for about 7 minutes until they are cooked through.
-
While the salmon is roasting, make the garnish.
For the garnish:
-
In a medium sized bowl, whisk the oil, lemon juice, maple syrup and mustard.
-
Dry the onions well on paper towels. Toss the arugula and onions into the bowl and toss the greens with the dressing.
-
To plate the dish:
-
In an individual serving bowl or on a dinner plate, spoon about 1 ½ cups of lentil ragout. Top with a piece of the oven roasted salmon, removing the skin if desired. (I do!)
-
Spoon about 1/3 cup of sauce over each oven roasted salmon filet and place the greens in the center of the salmon on top of the sauce.
-
Serve with any remaining sauce on the side.
