“A perfect summer grilling recipe, easy for entertaining. Fantastic as a prep ahead entrée. The squeeze of fresh lemon at the end adds an additional sparkle. In a pinch, when I need an extra-large dish for serving, I use half sheet pans lined with parchment paper.” — Mary Jo Romano

  5. Prepare a medium (350°F to 375°F) gas or charcoal grill fire. Clean and oil the grill grates. Make about 3 passes across the grill to create a nonstick surface.

Tips for Selecting and Cooking Trout

  • Make sure the trout is big enough to cut and stuff. Since trout is a delicate fish, it tends to fall apart easily, so a larger one will hold together better, also. Try to find some that are around 8 inches long. 
  • Your fish should be fresh and clean. Shiny scales, firm white flesh, with clear eyes, not cloudy. There should be no fishy smell, dried edges, or flesh discoloration. 
  • Your grill grate should be clean. A clean grate, cooking the filet hot and fast, and using a large heat-resistant spatula will help you cook your trout dinner quickly and easily. You can also grab a fish basket to use to make it even easier.
