Grilled Trout With Dill and Lemon

Recipe Image 12

This is the kind of recipe that makes you look like a grill master without needing a culinary degree or even knowing what “medium-rare” means for fish.

Fresh trout stuffed with bright lemon slices and aromatic dill creates this perfect balance of delicate, flaky fish with zesty, herbaceous flavors that’ll have your neighbors wondering what smells so incredible.

The aluminum foil boat technique is basically a foolproof cheat code – no fancy grill baskets required, no fish falling through the grates, just perfectly cooked trout every single time.

What makes this recipe absolutely brilliant is how the butter melts into the fish while the lemon slices steam from the inside, creating this amazing self-basting situation that keeps everything incredibly moist.

You’ll get restaurant-quality results with ingredients you probably already have, and the whole thing takes less than 35 minutes from start to finish.

Prepare yourself for that ultimate compliment: “Wait, you actually grilled this yourself?” Yes, Karen, some of us can handle fire and fish without calling the fire department.

Ingredients

For the Trout

2 whole trout, boned and cleaned (butterflied), head and tail on or headless
Extra virgin olive oil for coating and brushing
Kosher salt to taste
Freshly ground black pepper to taste

For the Stuffing

6 paper-thin slices fresh lemon, seeded
Several sprigs fresh dill (or basil, tarragon, parsley, or other tender herbs)
1 teaspoon butter, cut into small cubes

For the Foil Boat

Heavy-duty aluminum foil, doubled or tripled
Additional extra virgin olive oil for coating the foil

Instructions

Prepare the Grill

1 Fire up your grill for direct high heat, ensuring you have one section that stays cool for indirect cooking. This two-zone setup is crucial for preventing the delicate trout from overcooking while ensuring it gets properly heated through.

Create the Aluminum Boat

2 While your grill heats up, construct a “boat” using heavy-duty aluminum foil. Double or triple layer the foil for extra durability – you don’t want any tears that could cause your fish to stick or fall apart.
3 Form a 1-inch rim around all edges of the foil, creating walls that will contain the cooking juices and prevent any olive oil from dripping onto the grill grates.
4 Coat the bottom of your foil boat generously with extra virgin olive oil. This creates a non-stick surface and adds flavor while preventing the delicate trout skin from tearing when you remove it later.

Prepare the Trout

5 Rinse the trout under cold running water and pat completely dry with paper towels. Any excess moisture will create steam and prevent proper seasoning adhesion.
6 Open each fish like a book and season the inside cavity generously with kosher salt and freshly ground pepper. The seasoning should be visible but not overwhelming.
7 Arrange the 6 lemon slices in a single layer inside each fish cavity, ensuring even distribution. The lemon will steam from the inside, infusing the fish with bright citrus flavor.
8 Top the lemon slices with fresh dill sprigs, then dot with the small butter cubes. The butter will melt and baste the fish from within while the herbs add aromatic complexity.
9 Close the fish over the stuffing, then brush both sides thoroughly with extra virgin olive oil. This exterior coating helps with browning and prevents sticking.
10 Carefully place the prepared trout in your aluminum foil boats, ensuring they sit flat and stable.

Grill the Trout

11 Position the foil boats on the hot side of the grill and cover immediately. Cook for exactly 3 minutes – you’ll notice the oil and fish juices starting to bubble, which indicates proper heat transfer.
12 Move the boats to the cool side of the grill for indirect cooking. Cover and continue cooking for 3-5 more minutes until the fish is just cooked through. The flesh should be opaque and flake easily when tested with a fork, with an internal temperature of 145°F (63°C).

Recommended Equipment and Kitchen Tools

Recommended Tools (for best results)

Heavy-duty aluminum foil – Essential for creating leak-proof boats that won’t tear during cooking

Silicone basting brush – Perfect for evenly coating the fish with olive oil without tearing delicate skin

Helpful Upgrades

Digital probe thermometer – Allows continuous monitoring without opening the grill lid
Fish spatula – Wide, thin blade makes transferring cooked trout from foil to plate much easier
Microplane grater – If you want to add fresh lemon zest for extra citrus punch

Pro Tips and Troubleshooting

Professional Techniques

Score the skin lightly in a crosshatch pattern before seasoning to prevent curling and ensure even cooking. Always oil the foil generously – this isn’t the place to skimp, as it prevents sticking and adds flavor. Check doneness by gently lifting the flesh with a fork; it should flake easily and be opaque throughout.

Common Mistake Prevention

Never skip the two-zone grill setup – direct high heat the entire time will char the outside while leaving the inside raw. Don’t overcrowd the foil boats; each fish needs space for proper heat circulation. Resist the urge to flip the fish; the foil boat method cooks evenly from all sides.

Storage and Reheating

Leftover trout keeps refrigerated for 2-3 days and reheats beautifully in a 300°F (150°C) oven for 5-7 minutes. For meal prep, prepare the foil boats ahead and refrigerate up to 4 hours before grilling. The fish can also be served cold in salads or flaked into pasta dishes.

Scaling the Recipe

This recipe doubles or triples easily – just prepare additional foil boats and stagger cooking times if your grill space is limited. For larger crowds, consider using sheet pans in the oven at 350°F (175°C) for 12-15 minutes.
