How to Fillet a Trout the Right Way

Trout are an exciting species of fish to catch. You can traverse some of the most breathtaking scenery, just getting to them.

Trout can be challenging to catch and put up a good fight when hooked. Even the small one can give you a good thrill.

Trout is an absolutely delicious fish to eat.

Be sure to check out our full guide on Trout Fishing Tips.

In this article, I am going to cover how to properly fillet a trout. I am also going to cover one of the best trout recipes, that are completely irresistible.

Catching Trout

As with any fish, the sooner you can get the intestines out and the trout on ice the better. This can mean the difference between a fresh-tasting fish and one that has a strong “fishy” taste.

Fly fishermen carry a basket or storage container for caught fish. This works well to hold the trout until you are ready to call it a day.

Catching a trout to fillet
The best trout to eat are wild and without disease.

However, it doesn’t do much to keep the trout fresh. It is a good idea to keep a good cooler full of ice, near where you are fishing.

If you are in a boat, a cooler full of ice is definitely a better idea than a live well if you plan to take them home. It’s always a good idea to keep the meat cold to prevent spoilage.

Tools You Will Need to Clean and Fillet a Trout

A tool that you should pick up right away is a skinning board. This is a board with a clip on one end, designed to hold a fish while it is descaled and skinned.

Gutting trout
Do your best to keep the fish alive until you’re ready to gut it and put it on ice or cook.

A good, sharp fillet knife is a must. A good fillet knife will be razor sharp and hold its edge very well. More people are injured using a dull knife than a sharp one.

This happens when a large amount of force is applied to the fish using a dull knife.

Accidents happen. Protect yourself with a sharp knife.

A higher-quality fillet knife will fillet any fish effortlessly.

A pan of very cold water or ice water for putting your fillets in maintains the freshness of the fish. If fish is allowed to warm, it can actually change the texture of the meat and seriously affect the taste.

If you are going to store your fillets to prepare later, a freezer bag is a way to go. Put your fillets in the freezer bag and fill it with water.

The water should completely cover the fish. This helps prevent freezer burn and again, helps keep the fish tasting fresher.

When you are ready to cook your fillets, put the entire bag into a container of cool water. This will defrost the fillets slower preserving freshness.

Method for Filleting a Trout

trout fillet
Depending on the size of the trout, you can either fillet it or throw them directly on the grill whole.
  1. Remove the head of the trout. Filleting should be done when you wish to serve only the best quality of the fish, rather than cooking it whole.
  2. Start by cutting through the neck of the trout at the groove of the gills. Angle the blade of your knife so that you are cutting toward the head rather than the body to preserve the meat.
  3. Cut the first fillet along the top of the backbone. Place the trout on its side with the belly facing away from you. Start a small cut on the top side of the backbone at the opening where you removed the head.
  4. Insert your filleting knife into this groove and run the knife down the length of the fish, staying just above the backbone. Finish by slicing through the section at the base of the tail. You now have a clean, meaty fillet. (If you’re staying close enough to the backbone, you should be able to hear an audible clicking as you slice through the rib bones.)
  5. Flip the trout over and cut the second fillet. Turn the trout over on its opposite side and repeat the filleting process. Start the cut at the head and slice smoothly along the upper edge of the backbone until the entire fillet has been cut away.
  6. Remove the pin bones. Place each fillet skin side down and pick out each and every pin bone you find. Scrape along the flesh with your knife or pick up each fillet and flex it to expose bones that are lodged deep.
  7. Get rid of the skin. Now that the trout have been filleted and deboned, you only need to make one more cut to remove the skin. Take hold of the fillet on the tail end and use your filleting knife to cut into the flesh at an angle until you reach the outer layer of skin. Run the knife edge along the bottom of the fillet while tugging the skin lightly in the opposite direction. The skin should come away clean.

Again, while it is not necessary to remove the skin prior to cooking, it is commonly done when filleting fish and makes it easier to eat.

Grilling Trout

If you find yourself with a trout that is too small to fillet, then it’s recommended that you throw it on an open fire with a little oil on the outside. You can also throw some seasonings on the inside and outside for taste.

I like to use a little garlic salt and pepper and once cooked spritz some lemon over the top.

The trout meat should fall right off the skin and pairs well with rice or noodles.

Frequently Asked Questions

Q: How to gut a trout?

A: Step 1. Hold the fish firmly in your non-dominant hand, belly up. With the blade of the knife facing away from you, insert the tip into the vent and run the knife up the abdomen until it reaches a point between the pectoral fins.

Step 2. Make two incisions behind and underneath the gill plates.

Step 3. Push your index finger and thumb deep into the incisions, firmly pinch together and snap the flesh connecting to the jaw.

Step 4. Hold the gills tightly and pull hard to remove the gills, pectoral fins and entrails.

Step 5. Slice along the membrane covering the kidneys, and scoop out the kidneys using your thumb or blade of the knife.
