Halibut is a dense but flaky fish that is delicious when cooked on the grill. It’s firm and has a meaty texture, almost like a steak.
It’s quick to grill, making it great for weeknight dinners. Because it has a mild taste and firm texture, it pairs with a wide range of seasonings and flavors, and this lemon butter garlic sauce hits the spot every time.
Next time you’re in the mood for fish, fire up the grill and give this grilled halibut a go!
Grilled Halibut with Easy Lemon Garlic Butter Sauce
Halibuts’ firm texture holds up well to grilling, roasting, or searing. It also pairs well with bolder sauces and seasonings.
If you don’t like overly “fishy” tasting fish, Halibut is a good choice with a really clean and slightly sweet taste to it. There is no real aftertaste or lingering fishy flavor like you get with other species.
Ingredients you’ll need
- Halibut – The Halibut I used is from Snake River Farms. It comes flash-frozen to preserve the freshness in packs of 2 x 5 oz filets.
- Kosher salt
- Black pepper
- Olive Oil
- Unsalted butter
- Herbs – thyme and dill. Fresh is best but dried will do if that’s all you have.
- Lemon – juice only.
Equipment you’ll need
- Microwave – the butter needs to be melted; this could be done on the stovetop as well.
- Basting brush
How to make Grilled Halibut with Lemon Garlic Butter Sauce
1. Make the sauce
Melt a stick of butter in the microwave. Then add the minced garlic, lemon juice, and herbs, and combine well.
This butter sauce also goes great on grilled veggies like asparagus or peppers.
2. Prep the fish
Pat the filets dry with a paper towel and coat them with olive oil.
Season both sides with Kosher salt and freshly cracked black pepper.
3. Fire up the grill
Fire up the grill to medium/high, around 400°F.
Place the fillets directly on the grill.
Brush the fish with the lemon butter sauce several times as it cooks.
Make sure you only flip the fish once. It’s important when grilling fish not to handle it too much as you don’t want the fish to fall apart and slip through the grill grates.
Be careful to watch the internal temperature of the fish when grilling, as it cooks pretty fast. You only need 5-7 minutes per side, depending on the actual temperature of the grill and the thickness of the filet.
Once the internal temperature of the halibut reaches 140°F, brush on some more of the sauce and remove it from the grill.
A good instant read thermometer will ensure you pull the fish off at the right temp and don’t dry it out.
Once removed, add a touch more of the sauce and serve right away!
