A True Omega-3 Powerhouse

This Flaxseed-Crusted Salmon recipe is a fantastic way to incorporate healthy Omega-3 fatty acids into your diet, which are essential for brain health and reducing inflammation. This dish cleverly delivers a triple dose of these incredible nutrients:

  1. Salmon: One of the best natural sources of the Omega-3s EPA and DHA.
  2. Flaxseed: The ground flaxseed crust is packed with the plant-based Omega-3, ALA.
  3. Walnuts: The toasted walnuts in the salsa are another excellent source of ALA.

It’s a truly nourishing meal that makes healthy eating feel incredibly indulgent.

The Secret to a Healthy, Crunchy Crust

The magic of this Flaxseed-Crusted Salmon lies in its unique and incredibly healthy crust. Instead of a traditional breadcrumb coating, we use two key ingredients:

  • Dijon Mustard: A thin layer of tangy Dijon mustard is brushed over the salmon first. This not only adds a wonderful, sharp flavor that cuts through the richness of the fish, but it also acts as the perfect “glue” for our crust to adhere to.
  • Ground Flaxseed: We then sprinkle ground flaxseed over the mustard. When baked, the flaxseed toasts and creates a wonderfully nutty, slightly crispy, and textured crust. It’s a brilliant, gluten-free way to add texture, fiber, and a huge nutritional boost to the dish.

The Key Ingredients for Your Flaxseed-Crusted Salmon

This recipe uses a handful of fresh, vibrant ingredients to create a sophisticated and balanced meal.

  • Skin-On Salmon Fillets: The star of the show. Cooking the salmon with the skin on helps to protect the delicate flesh from drying out in the oven. Look for high-quality, wild-caught salmon for the best flavor.
  • Ground Flaxseed: Also known as flax meal, this can be found in the baking or health food aisle of your grocery store.
  • For the Grape and Walnut Salsa:
    • Red Grapes: Sweet, juicy, seedless red grapes, halved, provide a wonderful burst of sweetness.
    • Toasted Walnuts: Toasting the walnuts is a crucial step that deepens their flavor and makes them extra crunchy.
    • The Vinaigrette: A simple, perfectly balanced dressing of red wine vinegar, raw honey, and good-quality extra-virgin olive oil.
    • Fresh Herbs & Aromatics: Fresh parsley and thinly sliced scallions provide a final, fresh, and savory bite.

Step-by-Step Guide to Your Flaxseed-Crusted Salmon

This elegant meal comes together with just a few minutes of prep and a quick bake in the oven.

Part 1: Preparation

  1. Toast the Walnuts: Preheat your oven to 350°F. Spread the walnut halves on a sheet pan and bake for about 8 minutes, until they are lightly toasted and fragrant. Transfer them to a cutting board to cool, then give them a rough chop.
  2. Increase Oven Temperature: Increase the oven temperature to 400°F. Line a sheet pan with foil for easy cleanup.
  3. Prepare the Salmon: Using paper towels, pat the salmon fillets completely dry on all sides. A dry surface is key to a good crust.
  4. Create the Crust: Evenly coat the top (flesh side) of each salmon fillet with 1/2 tablespoon of the Dijon mustard. Season the fillets on all sides with salt and pepper. Sprinkle 1/2 tablespoon of the ground flaxseed on top of each piece of fish, gently pressing it into the mustard to help it adhere.
  5. Ready for the Oven: Place the prepared fish on the lined sheet pan. Drizzle each fillet with 1 tablespoon of olive oil.

Part 2: Bake the Salmon and Assemble the Salsa

  1. Bake the Salmon: Transfer the sheet pan to the hot oven and bake for about 10 minutes. For a perfect, moist, and tender result, use an instant-read thermometer. The Flaxseed-Crusted Salmon is done when the internal temperature reaches 125°F for medium-rare.
  2. Make the Salsa: While the salmon is baking, prepare your salsa. In a medium bowl, whisk together the remaining 4 tablespoons of olive oil, the red wine vinegar, and the raw honey. Season the vinaigrette with a pinch of salt and a twist of black pepper.
  3. Combine the Salsa: Add the chopped toasted walnuts, the halved red grapes, the chopped fresh parsley, and the thinly sliced scallions to the bowl with the vinaigrette. Toss everything together.
  4. Serve: When the fish is done, remove it from the oven. Top each piece of hot Flaxseed-Crusted Salmon with a generous amount of the fresh grape and walnut salsa and serve immediately.

Ingredients

Scale
  • 1 cup walnut halves
  • 4 skin-on salmon fillets (6 ounces each), pin bones removed
  • 2 tablespoons Dijon mustard
  • Kosher salt and freshly ground black pepper
  • 2 tablespoons ground flaxseed
  • 8 tablespoons (1/2 cup) extra-virgin olive oil

  2. Increase the oven temperature to 400°F. Line a sheet pan with foil.
  3. Using paper towels, pat the salmon fillets dry. Evenly coat the top of each fillet with 1/2 tablespoon of Dijon mustard.
  4. Season the fillets on all sides with salt and pepper. Sprinkle 1/2 tablespoon of ground flaxseed on top of each piece of fish, gently pressing it into the flesh.
  5. Place the prepared fish on the lined sheet pan and drizzle each fillet with 1 tablespoon of olive oil.
  6. Bake for about 10 minutes, or until an internal thermometer reads 125°F.
  7. Make the Salsa: While the fish bakes, whisk together the remaining 4 tablespoons of olive oil, the red wine vinegar, and the honey in a medium bowl. Season with a pinch of salt and a twist of black pepper.

Notes

  • This recipe uses a two-temperature oven process: a lower temperature for toasting the walnuts and a higher temperature for baking the salmon.
  • Patting the salmon fillets dry is an important step to help the crust adhere and the skin to cook properly.
  • Using an instant-read thermometer to check for a temperature of 125°F is the best way to ensure the salmon is perfectly cooked and not dry.

Frequently Asked Questions (FAQs)

My salmon was dry. What did I do wrong?

You overcooked it. Salmon is a delicate fish that is best when cooked to medium-rare. The 125°F internal temperature recommended in the recipe is perfect for a moist, flaky result, as the fish will continue to cook slightly from residual heat after you remove it from the oven. An instant-read thermometer is the best tool to prevent dry salmon.

Can I use a different kind of nut in the salsa?

Yes! While walnuts are fantastic, this salsa would also be delicious with toasted, chopped pecans or pistachios.

What should I serve with this Flaxseed-Crusted Salmon?

This is a wonderful, balanced meal on its own. However, if you’d like to make it heartier, it is fantastic served over a bed of fluffy quinoa, wild rice, or with a side of roasted asparagus or steamed green beans.
