Step 1

Preheat the oven to 450 degrees Fahrenheit. Line a rimmed baking sheet with aluminum foil or parchment paper.

Step 2

In a skillet or small saucepan, melt the butter. Add the shallot and cook on medium heat for about 3 minutes, until the shallot softens.

Step 3

Add the garlic and the lemon zest, cook for another minute. Cool slightly. Squeeze in half of the lemon juice.

Step 4

Place the fish on the prepared baking sheet. If it’s really big, lay it diagonally across the baking sheet. Season with salt and pepper.

Step 5

Spoon the butter over the fish.

Step 6

Sprinkle with half of the minced dill.

Step 7

Roast in the oven for 12-17 minutes, depending on how thick the fish is. The best way to check for doneness is to use a fork to gently prick the fish, and if it flakes easily, it’s ready.

Step 8

Use several spatulas to take the fish off the baking sheet in one piece. (Or cut it into sections, if it’s easier.)

Step 9

Squeeze the other half of the lemon over the fish and sprinkle with more fresh dill.
