Most families underestimate how fast salmon cooks. A 200g fillet at 200°C is done in 12-15 minutes. That's faster than pasta water comes to a boil, which means salmon is genuinely one of the quickest proteins you can put on the table - it just doesn't feel that way until you've done it a few times.
Add roughly 200 kcal and 40g carbs per serving if you include a portion of rice or potatoes.
Farmed Atlantic salmon is the most widely available and consistently the most affordable - typically $12-18 per kg depending on location. It's fattier than wild-caught, which means it's more forgiving in the oven and harder to overcook. If wild salmon is on special, the flavour is more pronounced but the margin for overcooking is smaller - pull it at 12 minutes and check.
Frozen fillets work well in this recipe. Thaw overnight in the fridge or under cold running water for 20 minutes. Pat very dry before adding the butter mixture - moisture is the enemy of any kind of surface browning.
Salmon is one of the few proteins that doesn't reheat well - the texture changes noticeably after a day in the fridge. Make exactly what you'll eat tonight. The butter mixture, however, can be made 3 days ahead and stored in the fridge.
