We gave ourselves a simple goal for this year, get good at cooking fish. In the past we shied away from even ordering it at restaurants because it was always second fiddle to one of the many shellfish specials at places like Red Lobster. Have you ever heard of their Endless Troutfest promotion?
Didn’t think so. It’s just not as exciting. But fish done right can taste amazing! It’s lean and full of protein, as well as being a good break from the usual terrestrial meats.
At first glance, cooking fish can be intimidating. You do need to keep an eye on it because it’s a protein that can easily go from underdone to overcooked. Preparing it on the stove puts the control back in your hands. Using a cast iron pan gives you a fantastic sear that will liven up any seasoning you throw on it.
We decided to test the waters and practice with Cast Iron Seared Rainbow Trout and Pan Roasted Brussels Sprouts with Bacon from America’s Test Kitchen’s Paleo Perfected.

What we’ve learned with this recipe about cooking fish:
- Thaw in the fridge overnight if not using fresh fish. This is the safe way to do it. We’ve run into problems where it’s not thawed by the time we want to cook. Make sure to put it in the front of your fridge to avoid this. You don’t want to try and cook the fish when it still has ice crystals. Be sure to plan ahead so your fish is thawed in time.
- Use a fish spatula. This makes getting under the fish and flipping it much easier. Regular spatulas have longer handles which means less control. You want to handle your fish carefully when flipping or it will turn into a flaky mess in the pan.
- Dry your fish completely. This can be a fish out of water story that ends well if you dry it with paper towels. You can’t get a good sear for a crispy skin; it will simply steam if it’s not completely dry first. Not only does this maillard reaction give the fish more flavor, it also helps with the aforementioned problem of flaking apart in the pan. Speaking of which, use ghee for your cooking oil.
- Ghee works better than butter. Clarified butter already has the water removed.
- Don’t remove the skin prior to cooking. The skin will hold the fish together making it easier to flip and is easier to remove afterwards.
