# Expert Tips:

01 -
  • The fish stays impossibly moist because you're not overthinking it—just oil, salt, and the oven doing the real work.
  • That lemon butter sauce tastes restaurant-quality but takes fewer minutes than most side dishes.
  • It reads fancy but honestly easier than pasta, and naturally gluten-free without any substitutions or fuss.
02 -
  • Don't wash the fish under running water after defrosting—it washes away flavor and moisture that you need for tenderness, just pat it dry instead.
  • Overcooked halibut becomes rubbery and you can't fix it, so pull it out the moment it turns opaque, not after.
  • Making the sauce while the fish bakes means everything comes together hot at the same moment, which is when this dish reaches its full potential.
03 -
  • If your fillets are thicker than an inch, they might need an extra few minutes, so invest in an instant-read thermometer and aim for 145°F in the thickest part.
  • Make the sauce up to an hour ahead and gently reheat it just before serving—it saves stress and lets you focus on getting the fish perfectly timed.
