Why Use a Cast Iron Skillet for Halibut?
The cast iron skillet is a versatile and terrific tool that offers even heat distribution and retention, making it perfect for cooking delicate proteins like halibut. It guarantees a crispy, golden crust while keeping the interior moist and tender. Additionally, it allows flavor to develop fully, enhancing the natural taste of the fish.
Ingredients to Have Ready
Before diving into the cooking process, youll need the following ingredients:
- Fresh halibut fillets (~6 oz per person)
- 1-2 tablespoons olive oil or avocado oil
- 1 tablespoon unsalted butter
- Sea salt and freshly cracked black pepper (to taste)
- 1 lemon (sliced or juiced for garnish)
- Optional: minced garlic, chopped dill, or parsley for added flavor
Preparing the Halibut Before Cooking
1. Selecting Fresh Halibut
Always choose halibut fillets with a fresh, ocean-like aroma. Avoid fillets that have any strong fishy smell, discoloration, or are too dry. Sushi lovers know, quality is key!
2. Pat Dry the Fillets
Use a paper towel to pat the fillets dry. This step ensures the external moisture doesnt interfere with building a beautiful, crispy crust.
3. Proper Seasoning
Generously season each side with sea salt and black pepper. To elevate the taste, you can lightly rub the fillets with olive oil before seasoning.
Step-By-Step Guide: How to Cook Halibut in a Cast Iron Skillet
1. Heat the Skillet Properly
A cast iron skillet requires preheating to ensure the fish doesnt stick. Place your skillet on medium-high heat and let it warm up for 3-5 minutes. Add your chosen cooking oil, ensuring it has a higher smoke point, such as avocado or grapeseed oil.
2. Start with Skin-Side Down
Place the halibut fillet skin-side down in the skillet. This helps the skin become crispy and prevents overcooking.
3. Avoid Overcrowding
If youre cooking multiple fillets, ensure theres enough space between them. Overcrowding can cause the temperature to drop, resulting in steaming rather than searing.
4. Cooking Time
Cook for about 4 minutes on the first side without moving or flipping. Flip the fillet carefully using a fish spatula and cook for another 3-4 minutes. Halibut is done when its internal temperature reaches 130F, and it flakes easily.
