How to Make Walnut Rosemary Crusted Salmon
1. Prep the oven
Preheat your oven to 425°F.
Line a baking sheet with parchment paper.
If your salmon is frozen, thaw it completely and pat it dry.
2. Make the lemon mustard glaze
In a small bowl combine:
• Lemon zest
• 1 teaspoon lemon juice
• Dijon mustard
• Garlic
• Rosemary
• Salt
• Honey
• Crushed red pepper
Mix until smooth.
This mixture adds brightness and helps the crust stick to the fish.
3. Make the walnut crust
In another small bowl combine:
• Panko breadcrumbs
• Finely chopped walnuts
• Olive oil
Mix until evenly coated.
The oil helps the crumbs toast beautifully in the oven.
4. Coat the salmon
Place salmon on the prepared baking sheet.
Spread the mustard mixture evenly over the top.
Sprinkle the walnut crumb mixture over the salmon and gently press so it sticks.
Lightly spray the top with olive oil cooking spray.
5. Bake
Bake salmon for 4–6 minutes per ½-inch thickness.
The salmon is done when:
• It flakes easily with a fork
• The center is opaque
• The crust is lightly golden
Tips for Perfect Salmon
Pat the fish dry
This helps the crust stick better.
Don’t overcook
Salmon continues cooking slightly after removing from the oven.
Use fresh rosemary if possible
It adds incredible aroma and flavor.
What to Serve With Walnut Crusted Salmon
This salmon pairs beautifully with simple Mediterranean sides like:
• Roasted asparagus
• Garlic green beans
• Lemon rice
• Herb roasted potatoes
• Simple arugula salad
It’s also fantastic served over quinoa or couscous.
Storage and Reheating
Store leftovers in an airtight container in the refrigerator for up to 3 days.
To reheat:
• Warm gently in a 350°F oven for 6–8 minutes
• Or reheat in a skillet over low heat
Avoid microwaving if possible to keep the crust crisp.
