Essential Equipment You’ll Need for This Recipe
- Large skillet
- Spatula
- Small saucepan
- Mixing spoon
Essential Ingredients to Bring This Dish to Life
- 4 halibut fillets (about 6 oz each)
- Salt and pepper, to taste
- 2 tbsp olive oil or avocado oil
- 4 tbsp unsalted butter, divided
- 3 garlic cloves, minced
- Juice and zest of 1 lemon
- 1/4 cup chicken or vegetable broth
- Fresh parsley, chopped, for garnish
- Lemon slices, for serving
Cooking Instructions: From Prep to Plate
- Prepare the Halibut
Pat the halibut fillets dry with a paper towel to remove any excess moisture. Season both sides with salt and pepper. - Sear the Halibut
Heat the olive oil in a large skillet over medium-high heat. Once the oil is hot, add 2 tbsp of butter, letting it melt and sizzle. Carefully place the halibut fillets in the skillet and cook for about 3-4 minutes per side, depending on thickness, until golden brown and cooked through. The fish should be opaque and flake easily with a fork. Transfer the cooked fillets to a plate and cover lightly with foil to keep warm. - Make the Lemon Butter Sauce
In the same skillet, add the remaining 2 tbsp of butter. Let it melt over medium heat, then add the minced garlic and cook for 1 minute, or until fragrant. Pour in the chicken or vegetable broth and stir, scraping any browned bits from the pan for extra flavor. Add the lemon juice and zest, stirring to combine. Let the sauce simmer for 2-3 minutes to slightly reduce and thicken. - Serve
Spoon the lemon butter sauce over the halibut fillets and garnish with fresh chopped parsley. Serve with lemon slices on the side for an extra citrusy burst.
Expert Tips for Making This Dish Even Better
- Use Fresh Halibut: Fresh halibut has a milder taste than frozen and works beautifully with this dish.
- Adjust Cooking Time for Thickness: Thicker fillets may need a minute or two longer per side. Just make sure not to overcook, as halibut can dry out.
- Add Extra Flavor: For an extra herby touch, add a few sprigs of fresh thyme or rosemary while the sauce simmers.
How to Store Your Dish for Maximum Freshness
- Refrigeration: Store leftover halibut in an airtight container in the fridge for up to 2 days.
- Reheating: Gently reheat in the oven at 300°F for 5-8 minutes or in a skillet on low heat to keep the fish tender.
