Pistachio Crusted Salmon Recipe

A Naturally Gluten-Free Crusted Salmon Upgrade

A blend of chopped pistachios, lemon, Dijon mustard, garlic, cumin, and honey adds irresistible flavor to this salmon recipe, plus the satisfying gluten-free crunch and textural interest I’m looking for.

Pistachios and salmon may not seem like an intuitive pairing at first. But pistachios have a buttery, woody flavor that matches salmon’s richness.

Best of all, while it looks and tastes elegant, pistachio-crusted salmon is surprisingly quick and easy to prepare. Because it takes about 20 minutes, I make this pistachio-crusted salmon as often on a busy weeknight as I do for a no-stress, impressive dinner party course. I add a quick side like Italian green beans, and dinner is served!

Key Ingredients

• Salmon fillets: You can buy salmon fillets, or use a 1 1/4- to 1 1/2-pound center-cut fillet and slice it into 4 (5- to 6-ounce) portions. I prefer center-cut salmon fillets because they have a more even thickness throughout, which helps them cook evenly. Depending on your preference, you can leave the skin off or remove it. 
• Extra virgin olive oil adds rich flavor to the pistachio crust and helps it brown while baking.
• Lemon: Fragrant lemon zest and bright lemon juice balance the richness of the salmon and heighten the nutty pistachio flavor.
• Honey: A touch of honey balances the tartness of the lemon juice and helps the crust brown in the oven, resulting in a flavorful, toasted crust.
• Dijon mustard introduces a piquant flavor and emulsifies the olive oil and lemon juice for a stable, evenly seasoned topping.
• Garlic: One minced clove is enough to add savory garlic flavor to the pistachio topping without taking over.
• Pistachios: Chop the pistachios fine enough for the topping ingredients to hold together but coarse enough to maintain some texture.
• Ground cumin adds a warming, earthy note that highlights the nutty flavor of the pistachios.
• Fresh dill and salmon were made for each other. Garnishing the filets with fresh dill fronds before serving adds a vibrant, herbaceous flavor.

How to Make Pistachio Crusted Salmon

• Get ready. Preheat the oven to 400°F. Line a baking sheet with parchment paper or aluminum foil.
• Prepare the salmon fillets. Pat 4 (5-6 ounce) skin-on salmon fillets dry with paper towels. Place them on the lined baking sheet, spacing them about 1-inch apart. Season generously with salt and freshly ground pepper.
• Prepare the pistachio topping. In a small bowl, whisk together 1 tablespoon olive oil, lemon zest from 1 lemon, 1 tablespoon lemon juice, 2 teaspoons honey, 1 1/2 teaspoons Dijon mustard, 1 clove minced garlic, and 1/2 teaspoon ground cumin. Add 3/4 cup (3 ounces) chopped pistachios and stir to combine.
• Coat the salmon. Evenly divide the pistachio topping among the salmon fillets, pressing it into place so it sticks.
• Bake the salmon. Bake the salmon for 8 to 10 minutes, or until the fillets are firm and just cooked through and the pistachio crust looks toasted and lightly browned.
• Serve. Transfer the salmon to a serving platter or individual plates. Garnish with some fresh chopped dill and lemon wedges.

Salmon Tips 

If you’ve ever wondered why salmon turns white when cooked, it’s because of a protein called albumin (the same protein in egg white). Albumin is a liquid protein that solidifies and becomes opaque as it heats. The muscle fibers in the salmon contract in response to heat, pushing the solidified albumin to the surface of the salmon. The more the salmon cooks, the more albumin is pushed to the surface.

All salmon contains albumin; it’s not an indication of the quality of the salmon. It’s flavorless and completely safe to eat, but admittedly, it doesn’t make for the most appetizing appearance. You likely won’t completely prevent albumin from seeping out of your salmon, but you can reduce it by avoiding overcooking or cooking it too quickly. 

The USDA recommends cooking salmon to 145°F. I personally prefer 130°F for medium-rare to 135°F for medium. In this recipe, the pistachio crust also helps protect the salmon from the oven’s heat. Baking at 375°F toasts the pistachio crust without being so hot as to turn the salmon white.

Make it Your Own

You can adjust the pistachio topping to your preferences or the ingredients you have on hand. The topping also works well on other types of fish. Try these variations:

• Substitute the lemon: lime or orange pairs well with pistachios, allowing you to switch things up based on what you already have on hand.
• Swap out the fish: use this pistachio topping on other types of fish, such as trout, sea bass, halibut, or cod. Adjust the cooking time to suit the thickness of the fillets.
• Drizzle it with a sauce: make a batch of this creamy dill sauce.

Perfect Pairings

Pair salmon with a salad for a lighter lunch, or a starch and vegetable for a heartier dinner. Here are some of my favorites:
