Slow Roasted Halibut Recipe with Herb Salsa

This recipe is the best way to cook halibut: slow roasted and served with an herb salsa. Every bite is rich and buttery and melts in your mouth. Topped with a vibrant herb salsa, this recipe will become your go-to for all types of fish.

When is Halibut Season?

Halibut season runs March-November on the Pacific coast, and it’s during this time that terrific halibut can be readily found in stores. If I’m unable to make it to my local fishmonger, I find that my local Costco often has a good selection of fresh wild-caught fish. I prefer to cook fillets, but a steak (cut the opposite way of a fillet), works in this recipe too. When choosing fish fillets, I look for ones that are an even thickness all the way through, so that they cook evenly.

The Best Way to Cook Halibut: Slow Roasting

Slow roasting is a wonderful method for cooking fish, because it is very forgiving. The temperature is so low, that even if the fish is cooked too long, it won’t dry out. The result is a very soft and buttery fish. It can also be applied to other fish varieties with high fat content, such as wild salmon or steelhead trout.

Herb Salsa

Herb salsa, or salsa verde, refers to a mixture of fresh herbs with vinegar, olive oil, and salt. The method in the recipe below can be applied to almost any herb combination. The recipe as written below calls for Italian parsley, but feel free to mix it up however you like. If you’re unfamiliar with cooking with herbs, an herb salsa is a great place to start–just pick up a bunch of parsley or cilantro the next time you go shopping. Herb salsa is great over cooked meats, eggs, and veggies. It’s fresh and vibrant in flavor, and lasts up to 3 days in the fridge.

Easy Healthy Dinners

Recipes to try serving with this dish are lemon arugula pasta, or sweet potato wedges or chili and cinnamon.

    I made this – added chives and chervil to the salsa and it worked out well! So delicious – and for a dinner party, so easy just to have it slow roasting in the oven!
