Slow roasting salmon is one of my favorite simple cooking methods that keeps the salmon juicy and full of flavor. You bake the salmon low and slow, leaving you with a flakey fish with delicious citrus dill flavor.

This dish is easy enough to make for a family weeknight dinner, and pretty enough to serve at your next dinner party. It’s made with the simplest ingredients and packs in so much flavor.

This recipe takes 10 minutes of prep time and comes together in one dish. The seasoned salmon is baked over a bed of thinly sliced red onion, green olives and lemon slices and topped with a few simple spices and fresh herbs.

I love serving this during the week with my harissa roasted potatoes or Halloumi Kale Salad with Harissa Dressing.
