What Is Pesto Crusted Salmon and How Does It Taste?

Pesto crusted salmon is a beautifully simple dish where fresh salmon fillets are topped with a layer of basil pesto mixed with breadcrumbs and Parmesan cheese, then baked until the crust turns crisp and golden while the fish stays moist and flaky inside. The flavor is a gorgeous combination of nutty, garlicky pesto with the rich, buttery taste of salmon.

How to Make Delia Smith Pesto Crusted Salmon

• Prepare the oven: Preheat the oven to 200°C or 180°C fan. Position a shelf in the upper third of the oven so the pesto crust gets beautifully golden and crisp during baking.
• Prepare the baking tray: Line a baking tray with baking parchment and brush it lightly with a little olive oil. This prevents the salmon skin from sticking and makes cleanup much easier.
• Pat the salmon dry: Remove the salmon fillets from the fridge about 10 minutes before cooking so they come closer to room temperature. Pat each fillet thoroughly dry with kitchen paper. Season both sides with salt and freshly ground black pepper. Place the fillets skin-side down on the prepared baking tray, leaving a little space between each one.
• Make the pesto crust mixture: In a mixing bowl, combine the basil pesto, fresh white breadcrumbs, finely grated Parmesan cheese, chopped pine nuts, olive oil, and lemon zest. Stir everything together until the mixture is evenly combined. It should be slightly moist and clump together when pressed, which helps it stick to the salmon during baking.
• Top the salmon: Spread a thin layer of pesto directly onto the top of each salmon fillet first. This acts as a glue for the crust. Then divide the breadcrumb mixture evenly among the four fillets, pressing it gently but firmly onto the surface of each piece so it adheres well and forms a compact layer.
• Bake the salmon: Place the baking tray in the preheated oven and bake for 18 to 20 minutes. The crust should be golden brown and crisp, and the salmon should be just cooked through. The flesh should flake easily when tested with a fork but still look slightly translucent in the very centre, as it will continue cooking from residual heat once removed from the oven.
• Rest and serve: Remove the tray from the oven and let the salmon rest for 2 to 3 minutes. This allows the juices to settle and the crust to firm up slightly. Transfer to serving plates, garnish with fresh basil leaves, and serve with lemon wedges on the side for squeezing over.

Tips for Perfect Pesto Crusted Salmon

How do I stop the pesto crust from falling off?

The key is to pat the salmon completely dry before adding the topping. Moisture on the surface of the fish prevents the crust from sticking properly. Spreading a thin layer of pesto directly onto the salmon first creates a tacky base that acts like glue. Then press the breadcrumb mixture firmly onto that pesto layer. Avoid moving or flipping the fillets once they are topped, and let the oven heat do all the work from above to set and crisp the crust.

Can I use shop-bought pesto for this recipe?

Absolutely. A good quality shop-bought basil pesto works brilliantly here and saves you time. Look for one made with real basil, olive oil, Parmesan, and pine nuts for the best flavor. If you prefer to make your own, simply blend fresh basil leaves, garlic, pine nuts, Parmesan, and olive oil in a food processor until smooth. Homemade pesto tends to have a brighter, more vibrant flavor, but either option produces excellent results.

What type of breadcrumbs work best?

Fresh white breadcrumbs give the best texture for this recipe. They crisp up beautifully in the oven and create a light, golden crust. You can make them easily by blitzing day-old white bread in a food processor. Panko breadcrumbs also work well if you want an extra crunchy finish. Avoid very fine dried breadcrumbs, as they can form a dense, hard layer rather than a pleasantly crisp topping.

How do I know when the salmon is cooked through?

The salmon is ready when the crust is golden brown and the flesh flakes easily with a fork. If you press the thickest part of the fillet gently, it should feel firm but still have a slight give. For those who prefer to use a thermometer, the internal temperature should reach 62°C to 63°C for perfectly cooked salmon that is moist and flaky. Remember that the fish continues to cook for a couple of minutes after you take it out of the oven, so pulling it out when it is just barely done ensures it stays tender.

Can I prepare the pesto crust mixture ahead of time?

Yes, you can mix the breadcrumb and pesto topping up to a day in advance. Store it in an airtight container in the fridge and bring it to room temperature for about 10 minutes before using. You can also top the salmon fillets and keep them covered in the fridge for up to 4 hours before baking. This makes it a fantastic option for dinner parties where you want to do most of the work ahead of time.

Storage

Room Temperature

Cooked pesto crusted salmon should not be left at room temperature for more than 2 hours. If you are serving it as part of a buffet, keep it covered and try to serve within 1 hour for the best quality and food safety.

Refrigerator

Store leftover pesto crusted salmon in an airtight container in the refrigerator for up to 2 days. To reheat, place it on a baking tray and warm in a preheated oven at 160°C for 8 to 10 minutes. This helps the crust stay crisp rather than going soft. You can also enjoy it cold, flaked over a salad, which is a lovely way to use up leftovers.

Freezing

You can freeze uncooked, topped salmon fillets for up to 1 month. Place the prepared fillets on a baking tray lined with parchment, freeze until solid, then wrap individually in cling film and store in a freezer bag. Cook from frozen by adding an extra 5 to 8 minutes to the baking time. Already cooked salmon can also be frozen for up to 1 month, though the crust may soften slightly upon reheating. Thaw overnight in the fridge before warming through in the oven.
