Ingredients

  • Salmon fillets: provide healthy fats and protein always choose fillets with firm flesh and a fresh sea smell
  • Salt and black pepper: for basic seasoning opt for sea salt if possible
  • Garlic powder: brings a gentle savory aroma choose pure garlic powder without additives
  • Paprika: delivers warmth and a subtle sweetness look for vibrant red paprika for best flavor
  • Cayenne pepper: adds gentle heat use sparingly and taste as you go
  • Extra virgin olive oil: coats and protects the salmon always select cold-pressed for flavor
  • Avocados: give the topping its creamy richness select ripe but not mushy avocados that yield to gentle pressure
  • Lime zest and juice: provide brightness and balance in the mash use fresh lime for the best zing
  • Chopped dill: lends an herby note to the mash look for soft feathery fronds
  • Chopped red onion: adds crunch and bite make sure it is crisp and brightly colored

Step by Step Instructions

Prepare the Oven:
Preheat your oven to three hundred seventy five degrees Fahrenheit Set up your oven rack in the middle slot for even heat This step ensures the salmon bakes evenly every time
Season the Salmon:
Lay your salmon fillets gently in a baking dish Sprinkle each fillet with a pinch of salt black pepper garlic powder paprika and cayenne Drizzle with olive oil and use your hands or a pastry brush to coat every surface thoroughly The seasonings will create a flavorful crust and the oil keeps the salmon moist
Bake the Salmon:
Slide the baking dish into the preheated oven Roast for twelve to fifteen minutes until the fillets are opaque and flake easily with a fork If the fillets are thick you may need an extra minute or two The high heat gently cooks and caramelizes the surface
Make the Avocado Mash:
While the salmon is baking pit and scoop your avocados into a bowl Use a fork to mash them until almost smooth Grate in the zest of one lime and squeeze in its juice Sprinkle with salt and add plenty of chopped dill Fold the ingredients together so you get creamy green mash with herby flecks and bits of zest
Finish and Serve:
Once the salmon is out of the oven spoon a thick layer of avocado mash on top of each fillet Scatter chopped red onion over everything for crunch and color Serve immediately while the fish is still warm and the avocado creamy

Avocado is the superstar here for me Nothing beats its vibrant creamy texture and lime zing I love watching my kids’ faces light up when they get a heaping spoonful of avocado on their salmon It reminds me of summer picnics where this combo was always the first to disappear

Storage Tips

Store leftover salmon and avocado mash separately to keep flavors fresh Salmon will keep in an airtight container in the fridge for up to two days For the avocado mash press a piece of plastic wrap directly onto its surface to reduce browning and use within twenty four hours Reheat the salmon gently in the oven to avoid drying it out

Ingredient Substitutions

If you are out of dill try fresh cilantro or parsley for a different herby twist Lemon can swap in for lime and if you want less heat replace cayenne with a pinch of smoked paprika Instead of red onion try thinly sliced green onion for a milder bite
