Note on fish to use: I like to use sea bass in this dish, preferably striped or Barramundi variety. Chilean sea bass, while popular, is actually not a sea bass; it’s a clever rebranding of Patagonian Toothfish. It’s also tasty, but keep in mind it’s higher in mercury. You can also use other, mild white fish including grouper, cod, haddock or even halibut. This pistachio crust is also delicious on salmon, too!

Note on fish cook time: While the general rule of thumb for cooking fish is 10 minutes per inch of thickness, I’ve included the option to cook these fillets for 12 minutes per inch. I find that with the crust on top, it can take a bit longer. It’s really to your taste — just remember, it will continue cooking after you take it out of the oven and let it rest.

Make ahead: Fish with topping can be prepared but not baked up to 4 hours in advance, covered and refrigerated.
