Grilled Halibut Fillets

, , , ,

These Mediterranean-inspired grilled halibut fillets are amazingly delicious and easy to make. Halibut lends itself well to live-fire cooking, and all you’ll need is a good spatula and a 12-14 minute cook time.

Ingredients for Grill Halibut Fillets:

  • 4 halibut fillets, about 6 ounces each
  • Olive oil
  • Minced Garlic
  • Lemons
  • Fresh rosemary
  • Fresh thyme
  • Sea salt
  • Black pepper

Marinating Halibut:

These grilled halibut fillets only need about 30 minutes of marinating time. Lemon juice or other acids can break down fish and seafood relatively quickly. They begin to “cook” the surface of the halibut if left on too long. The fish can also become mushy and hard to grill.

Grilling Halibut Fillets: 

These halibut fillets are cooked hot and fast, which means a shorter cooking time at a higher temperature. If you are new to grilling fish, I recommend using a wood plank the first couple of times. You won’t need to flip the fish on the grill if using a plank.

  • Preheat grill for medium-high heat, or between 375 to 400 degrees F.
  • Oil your grill grates using an oil-soaked paper towel held by a pair of outdoor cooking tongs. Make 3-4 passes across the grates.
  • Remove halibut from the refrigerator and season each fillet with salt and black pepper. Let the fish stand at room temperature for 5-10 minutes.
  • Place fish onto the grill grate and grill one side for 5 to 7 minutes. Flip the fish and continue cooking for another 5 to 7 minutes. 
  • Halibut is considered cooked once it reaches an internal temperature of 135 degrees F. Take the halibut fillets off the grill at 130 degrees and place them onto a warm plate. It should reach 135 degrees in a few minutes.
  • Store leftover fish in an airtight container in the refrigerator for 2-3 days.

  • Remove fish from refrigerator and season each steak with salt and black pepper. Let sit at room temperature while the grill comes up to temperature.
  • Place fish onto the grill grate. Grill on one side for 5 to 7 minutes. Flip and continue another 5 to 7 minutes. Halibut is ideally cooked to an internal temperature of 130 to 135 degrees F.
