# Expert Tips:

01 -
  • It's done in under 30 minutes, so weeknight cooking doesn't feel like a chore.
  • The fish stays impossibly tender while the garlic and lemon create a sauce that begs for crusty bread.
  • One pan means one thing to wash, which somehow makes the whole meal feel less exhausting.
  • It's naturally gluten-free and so elegant that you can serve it to anyone without feeling like you cut corners.
02 -
  • Don't skip patting the fish dry—moisture is the enemy of tender, delicate texture in baking.
  • Start checking for doneness at 15 minutes because halibut can go from perfect to dry in seconds, and all fish varies depending on thickness.
03 -
  • Use a meat thermometer if you're nervous—halibut is done at 145°F internally, which removes the guesswork entirely.
  • If your fillets are thinner than an inch, reduce the cooking time to 12 to 14 minutes so you don't dry them out.
