How to Make It
In a large cast-iron skillet, melt the butter over moderate heat. Add the minced garlic and cook, stirring, until fragrant, about 1 minute. Whisk in the herbs, then whisk in the lemon juice and season with salt and pepper. Remove from the heat.
Pat the bass fillets dry and season with salt and pepper. Working in 2 batches, add the fillets to the herb butter, skin side down; cover and cook over moderately low heat until they are just white throughout, 8 to 10 minutes. Transfer the fish fillets to plates, spoon some of the herb butter on top and serve hot.
