Step 1 · Roast the Tomatoes
Heat the oven to 450°F. Place the tomatoes on a rimmed baking sheet, sprinkle lightly with salt and roast for 10 minutes while you prepare the fish.
Step 2 · Prepare the Spice Butter
In a small bowl, stir together the butter, garlic, zest, spice blend and a pinch of salt.
Step 3 · Nestle the Fish
Season the fish lightly with salt. Remove the pan from the oven and nestle the fillets among the tomatoes. Pour the spice butter over the fish and tomatoes, tossing the tomatoes to coat them. Sprinkle the scallions over everything.
Step 4 · Finish Roasting
Roast until the fish is flaky and cooked through, about 5–10 minutes depending on the thickness of the fillets. Finish with a squeeze of citrus juice and fresh herbs, then serve.
