Method 1
Method 1 of 3:

Grilling Whole Trout

  1. 1
    Remove the trout’s gills and guts. Using a filet knife, make a straight cut on the bottom of the fish from the anal fin to the pectoral fins, stopping right before the gills. On the underside of the mouth, cut down on each side of the chin to create a V shape. Using scissors, cut from each of the pectoral fins to the trout’s adjacent gills. Grab the mouth cuts and pull back to remove the guts and gills.[3]
    • Though not required, you can remove the trout’s head and skin if desired. To do so, use your scissors to cut off each of the fins. After, pull the head back slowly to remove the skin. Clip the tail, then quickly rinse the fish to wash off any blood.
  2. 2
    Let your trout thaw until it is at room temperature. To make sure your fish grills evenly and thoroughly, make sure it is at room temperature before cooking. Do not grill cold or frozen trout, doing so will leave parts of your fish undercooked.

  3. 3
    Heat your grill to a medium temperature and oil the grates. If you’re using an electric or gas grill, set it to about 350 °F (177 °C). If you’re using a charcoal grill, set your embers to one side so you can place the trout on the other. When the grill is heated, run a cloth dipped in vegetable oil over the grates to keep the fish from sticking.
  4. 4
    Coat the trout with vegetable oil. Use a small brush to coat your fish with a layer of vegetable oil. This will keep in moisture while cooking and keep your fish from sticking to the grates.
  5. 5
    Sprinkle your fish with salt and pepper. Sprinkle salt and pepper over your trout to taste. Make sure to cover both sides. Be aware that, because the trout is being cooked whole, you may need to use more spice than normal.
  6. 6
    Stuff your trout with fresh herbs and citrus slices to help it absorb flavor. For extra taste characteristics, insert fresh dill, oregano, thyme, and parsley strands inside the main cavity. To add zest, insert slices of lemon or lime. Make sure these ingredients are spread out evenly within the fish.
  7. 7
    Place your trout on the grill and cook until it is well-browned. For most trout, each side should take between five and ten minutes to cook, depending on how thick it is. To see if it is done, look for skin that is browned and, if you like your fish well-done, very slightly blackened.[4]
  8. 8
    Use a spatula or tongs to flip the trout and cook the other side. Use a wide, flat spatula to flip the fish over. Cook until the other side is well-browned. The trout should pull off the grill easily, so if it doesn’t, let it cook a bit longer.

Method 2 of 3:

Grilling Foil Trout

  1. 1
    Gut and gill your trout. If you’re cooking fresh-caught trout, use a filet knife to slice the bottom of the fish from the anal fin to the pectoral fins, making an incision that ends immediately before the gills. Underneath the mouth, create a V shape by making small slices along the chin. With scissors, make cuts between the fish’s gills and nearby pectoral fins. To remove the guts and gills, grab the mouth and pull back.[5]
    • Trout can be cooked with the head and skin on, but you can remove them if desired by cutting off each of the fins and pulling the head back slowly. Make sure to clean the skinned fish before cooking.
  2. 2
    Place your trout in a sheet of aluminum foil, skin-side down. Lay out a large sheet of heavy-duty aluminum foil. Place your fish filet in the center of the foil, leaving enough room on the sides to wrap it up later.
  3. 3
    Heat your grill to a high temperature. Electric and gas grills should be set to around 400 °F (204 °C). If you’re using a charcoal grill, build the flame on one side so you can place your fish on the opposite end.
  4. 4
    Lightly sprinkle your fish with salt, pepper, and olive oil. Sprinkle pinches of salt and pepper over your fish to taste. After, drizzle olive oil over your fish to keep in moisture and flavor while on the grill.
  5. 5
    Cover your fish with fresh herbs and citrus slices. Lay fresh dill, oregano, thyme, and parsley evenly over the trout. For added tang and taste, spread out thin slices of lemon, lime, or other citrus fruits on the filet.
  6. 6
    Wrap the foil over your fish to make a small, sealed tent. When you’re ready to grill, wrap the aluminum foil around your filet. Make sure it is completely sealed to pack in steam. To give the package room to breathe, pull up on the foil to create a small pocket of air above the fish, making a small tent.
  7. 7
    Put your foil package on the grill and close the lid. Place your fish away from the direct flames. To help steam your fish, close the grill’s lid while cooking. Make sure the package is skin-side down with the tent pointed up.
  8. 8
    Cook your fish for about five minutes per .5 inches (1.3 cm) of thickness. In general, average-size trout filets take about ten minutes to cook. To see if your fish is done, use heat-resistant gloves to open the foil slightly. If the fish flakes easily when scraped with a fork and is opaque, it is ready to be served.

Method 3 of 3:

Grilling Cedar Trout

  1. 1
    Take out your trout’s gills and guts. To prepare fresh trout for grilling, take a filet knife and make an incision on the fish’s undercarriage between the pectoral fins and anal fin, stopping before the gills. Flip the fish on its back and make two cuts on the bottom of the mouth, creating a V shape. Using a pair of scissors, cut from each of the fish’s pectoral fins to the closest set of gills. Pull back on the trout’s mouth to remove the guts and gills.[6]
    • Though it is optional, you may want to remove the head and skin before cooking. To do so, chop off the trout’s fins and peel the head back slowly. Rinse the fish to wash off any blood.
  2. 2
    Soak your cedar plank in water for 2 hours. This will help your fish steam while grilling, letting it gain a naturally woody flavor from the plank. For extra taste dimensions, soak your wood in a cooking alcohol like wine or cider instead.[7]
  3. 3
    Set your grill to a high heat. For electric and gas grills, set the temperature to about 400 °F (204 °C). For charcoal grills, set your embers near the center so you can place the trout next to them.
  4. 4
    Oil your fish to keep in moisture. Spread a small amount of oil over your filet to pack in moisture while cooking. Combined with the cedar plank, this should keep your trout tender and juicy.
  5. 5
    Season your trout with salt, pepper, herbs, and citrus. Sprinkle a light amount of salt, pepper, dill, oregano, thyme, and parsley over the top of your trout. Depending on preference, either squeeze out a lemon or lime over your fish or place fresh citrus slices on top.
  6. 6
    Put your cedar plank on the grill and top it with the trout, skin-side down. Place your cedar plank to one side of the grill, off the direct flames. Place your trout on top to cook, making sure the skin-side is facing down and touching the plank.
  7. 7
    Grill until the fish is opaque and flakes easily. Cook your trout until it is opaque and flakes easily with a fork. For average-sized trout, this should take about 10 minutes. You do not need to flip this fish when cooking with a cedar plank.

    Yes. Each of the methods listed here uses oil, and the trout can be served with vinegar (and even extra oil, if you want).
  • Question
    How do I make it healthy with reduced sodium?

    If it is a pre-processed filet, put it in water and lightly rub the fillet while under water for about 10 - 15 seconds. Cook however you like from that point on, just make sure it isn't a curing process. If it is a fresh filet, cook how desired (I prefer to bake, pour a little unsalted butter on it, then add some spices if you like). Just don't 'cure', as that adds sodium.

After you've gutted your trout and removed the gills, set your grill to 350 °F. Then, coat the trout with vegetable oil, and sprinkle it with salt and pepper to taste. To help the fish absorb flavor, put a slice of lemon, or some fresh oregano and dill, inside the cavity. To cook, grill the trout for 5-10 minutes on each side, or until the skin is brown. If you'd rather grill a trout filet, place it on a sheet of foil, season it with oil and herbs, and wrap it up tightly. Put the package on the grill and cook at 400 °F for 5-10 minutes.
