Slow-Roasted Salmon With Mushroom Leek Broth Recipe

Slow-Roasted Salmon With Mushroom


For the Salmon:

  • 4 salmon fillets
  • Salt and pepper, to taste
  • Olive oil

For the Mushroom-Leek Broth:

  • 1 cup sliced mushrooms (such as cremini or shiitake)
  • 1 leek, cleaned and thinly sliced
  • 2 tablespoons butter or olive oil
  • 2 cloves garlic, minced
  • 4 cups chicken or vegetable broth
  • 1 teaspoon fresh thyme leaves
  • Salt and pepper, to taste


  1. Preheat the Oven: Preheat your oven to 275°F (135°C).
  2. Prepare the Salmon: Pat the salmon [1] fillets dry with paper towels—season both sides with salt and pepper. Drizzle a bit of olive oil over the fillets.
  3. Sear the Salmon: Heat a skillet over medium-high heat. Once hot, add a drizzle of olive oil. Sear the salmon fillets for about 2 minutes on each side until they get a golden crust. Remove from the skillet and set aside.
  4. Prepare the Broth: In the same skillet, melt butter (or heat olive oil) over medium heat. Add the sliced leeks and sauté for about 2 minutes until they soften. Add the sliced mushrooms and minced garlic, and cook for another 3-4 minutes until the mushrooms are tender.
  5. Create the Broth Base: Pour the chicken or vegetable broth and add fresh thyme leaves. Let the broth simmer for 15-20 minutes, melding the flavors together—season with salt and pepper to taste.
  6. Slow-Roast the Salmon: Place the seared salmon fillets in an oven-safe dish. Gently pour the prepared mushroom-leek broth over the salmon. Cover the dish with aluminum foil.
  7. Roast in the Oven: Place the covered dish in the oven and slow-roast the salmon for about 20-25 minutes, or until the salmon is cooked to your preferred level of doneness and flakes quickly with a fork.
  8. Serve and Enjoy: Carefully remove the dish from the oven. Serve the slow-roasted salmon fillets in bowls, spooning the flavorful mushroom-leek broth. Garnish with additional fresh thyme leaves if desired.

What’s The Essence Of Slow-Roasted Salmon?

The essence of slow-roasted salmon lies in its systematic cooking approach that results in a delicate and tender texture. 

Unlike traditional high-heat methods, slow-roasting involves gently cooking the salmon at a lower temperature over a more extended period. 

“I work on most weekends, so my husband is the executive chef. He is an amazing cook. I love the way he does salmon, and his apple pie for dessert is delicious.”

– Erica Durance, Canadian Actress

This gradual cooking process preserves the natural moisture within the fish, ensuring it remains succulent and almost melts in your mouth. 

As the salmon slowly cooks, it absorbs the flavors of any accompanying elements, like a mushroom-leek broth, resulting in a harmonious fusion of taste and tenderness that’s genuinely indulgent.x
