Ingredients + Notes/Substitutions

This recipe centers on four skin-on salmon fillets and a creamy avocado mash brightened with lime and dill. The mash is designed to be scoopable and lightly tangy, balancing the richness of the fish.

Salmon Fillets: Four, skin-on.
Seasonings: Salt, black pepper, garlic powder, paprika, cayenne pepper.
Olive Oil: Extra virgin.
Avocados: Two, ripe, for mashing.
Lime: Zest and juice.
Fresh Dill: Chopped.
Red Onion: Half, chopped.

Notes & Substitutions

Salmon: Fresh vs frozen works; if using frozen, thaw fully and pat dry. Wild-caught salmon offers a leaner profile, while farmed can be more forgiving if you’re budget-conscious.
Spices: Smoked paprika adds a subtly smoky note; swap or mix in chili powder for more heat.
Herbs: Cilantro or parsley can replace dill for a different aroma. Chives provide a mild onion bite.
Onion: Green onions or shallots are great stand-ins for a lighter bite.
Avocado: Ripe, creamy fruit yields the best mash; underripe avocados will be grainy.

Equipment

Baking Dish: Oven-safe.
Small Bowl: For avocado mash.
Fork or Masher: For avocados.
Grater or Zester: For lime zest.
Cutting Board & Knife: For prep.

Instructions

Preheat Oven: Set to 375°F (190°C).
Prepare Salmon: Place salmon fillets in a baking dish, skin side down.
Season Salmon: Rub with olive oil, then season with salt, pepper, garlic powder, paprika, and cayenne.
Bake Salmon: Slide into the oven and bake 12–15 minutes, until flaky.
Mash Avocados: While salmon cooks, scoop the flesh into a bowl and mash to your preferred texture.
Flavor Mash: Add lime zest, lime juice, and a pinch of salt; fold in chopped dill.
Combine Mash: Mix until evenly seasoned.
Chill Mash: Cover and refrigerate briefly to allow flavors to mingle.
Check Doneness: Salmon should flake easily with a fork and show no translucent center.
Serve: Top each fillet with a generous scoop of avocado mash.
Garnish: Scatter chopped red onion and extra dill for color and brightness.
Enjoy: Serve immediately while warm and creamy.

Pro Tips & Troubleshooting

Choosing Salmon: Look for thick, evenly cut fillets for uniform cooking.
Doneness: An internal thermometer nudges you to the 125–130°F (52–54°C) range for moist, just-flaky salmon.
To ensure food safety, the USDA recommends cooking salmon to an internal temperature of 145°F, at which point it will be fully cooked, creamy in color, and flaky. Learn more about safe cooking temperatures for salmon.
Prevent Dryness: Bake uncovered to help the surface stay crisp while the center remains juicy.
Flavor Boost: If time allows, marinate briefly in a light oil and spice rub for extra depth.
Avocado Ripeness: Ripeness is key for a smooth, lush mash; if you must, add a splash of water or lime juice to adjust texture.
Keep Mash Green: A squeeze of lime juice right before serving slows browning.
Adjust Spices: Tweak heat with more cayenne or a splash of hot sauce to taste.
Fresh Herbs: Dill’s brightness really shines; substitute with cilantro for a different note.

Serving Suggestions, Storage & Variations

Serving Suggestions: Pair with roasted vegetables, quinoa, or a crisp salad to complete a balanced plate.
Storage: Keep leftover salmon and mash separate in airtight containers in the fridge.
Reheating: Reheat salmon gently to avoid drying; mash can be served at room temperature or warmed lightly.
Meal Prep: Bake the salmon and prepare the mash ahead; combine when ready to eat for a quick finish.

Variations:

Spicy Kick: Add jalapeño to the mash for a lively heat.
Herby Twist: Try cilantro or parsley instead of dill.
Garlic Lover: Fold in minced garlic to the mash.
Mediterranean Style: Top with cherry tomatoes and a sprinkle of feta.
Asian Inspired: Drizzle with a touch of soy glaze and sesame seeds.
Citrus Burst: Fold in orange zest for a bright, sunny finish.

Frequently Asked Questions (FAQ)

Can I prepare the avocado mash ahead of time?

Yes, mash it a few hours ahead and store with a thin layer of lime juice to minimize browning. Re-whisk gently before serving.

What kind of salmon works best?

Fresh, high-quality fillets, preferably with skin on, deliver the best texture and flavor. If using frozen, thaw fully and pat dry before cooking.

It should flake easily with a fork and look opaque through the center. If using a thermometer, aim for 125–130°F (52–54°C).

Can I cook salmon in an air fryer?

Yes, you can. Lightly oil and season the fillets, then air fry at 400°F (204°C) for about 8–10 minutes, depending on thickness.
