Why This Recipe Works for Overlanders

Foil packet teriyaki salmon turns a fragile fillet into a foolproof camp dinner. First, the sealed foil steams the salmon gently so it stays moist while the teriyaki reduces into a glossy glaze. Then you serve it straight over rice with no pan to scrub. Because the packet protects the fish from direct flame, you avoid the dry, stuck mess of grilling salmon on a grate.

The method keeps delicate fish whole. Specifically, salmon falls apart when you flip it on a grill, but inside a flat-pack packet it cooks without handling. Since you never turn the fillet, it holds its shape from coal to plate. Also, the recipe scales from 2 to 6 people on the same medium coal bed.

A parchment liner solves the teriyaki acid problem. Because teriyaki sauce is acidic and salty, it pits bare aluminum foil over an 18-minute cook and leaves a metallic taste. When you line the foil with parchment first, the sauce never touches the metal. This recipe is part of the full foil packet camping recipes collection. While a cedar plank gives salmon a smoky edge, the dutch oven camping recipes collection covers heartier meals, and both roll up to our camp cooking for overlanders guide.

Ingredients

Step-by-Step Instructions

Prep at home (the night before, 10 minutes):

1. Pat the salmon dry: Blot each fillet with a paper towel, since dry salmon takes the glaze better and avoids a watery packet.
2. Mix the sauce: In a small jar, combine the teriyaki sauce, sesame oil, minced garlic, and half the sliced ginger. Then bottle it for the trip.
3. Pack cold: Bag the salmon, the sauce, and the green onion and sesame separately. Chill the salmon below 40F. Because the fish is raw, store it on the lowest cooler shelf away from ready-to-eat food.

At camp (dinner time):

4. Light the coals: Fill a chimney with 20 to 25 briquettes. Wait 15 to 20 minutes until they glow orange under a coat of gray ash. Medium coals run 350F to 400F, which cook salmon gently without drying it.
5. Line the foil: Center a 12-inch parchment square on each 14-inch foil square. Because teriyaki acid pits bare foil, the parchment keeps the sauce off the metal and out of your dinner.
6. Build each packet: Place a salmon fillet skin-side down on the parchment. Then spoon a quarter of the teriyaki sauce over each fillet and scatter the remaining ginger on top.
7. Flat-pack fold and double-wrap: Fold the parchment and foil edges up together and crease the seam down twice, leaving a little headroom. Next, fold the short ends up twice each. Wrap a second foil square around each packet for puncture protection.
8. Cook on the coals: Rake the coals into a flat single layer. Place the packets on the bed with long-handled tongs. Cook 8 minutes on the first side.
9. Rotate, do not flip: After 8 minutes, rotate each packet 90 degrees rather than flipping, since salmon breaks apart when turned. Then cook another 7 to 10 minutes. Total cook time runs 15 to 18 minutes on medium coals.
10. Check for flake: Open one packet and tilt the steam away from your face. The salmon should flake with a fork and reach 145F at the thickest point, the safe temperature for fish per USDA guidance.
11. Garnish and serve: Scatter the green onion and sesame seeds over each fillet. Then serve over rice with steamed vegetables, and pack out the cooled foil and parchment.

Coal Bed Math for Foil Packets

This packet cooks by direct coal contact, so judge heat by the coal surface rather than a briquette count around a Dutch oven. Match the look of the coals to the job below.

Foil packet teriyaki salmon runs best on medium coals at 350F to 400F, which cook the fish to a moist 145F without drying the edges. Three field adjustments shift the timing. First, when wind tops 10 mph, add 5 to 8 minutes. Second, when ambient temperature drops below 40F, add 3 to 5 minutes. Third, hot coals above 500F overcook salmon fast, so hold the bed at medium and pull the packet as soon as the fish flakes.

Field Tips for Cooking at Camp

The parchment liner is the key step for foil packet teriyaki salmon. Because the sauce is both acidic and salty, it eats into bare foil and leaves a metallic taste over a long cook. Instead, line every packet with parchment so the teriyaki only touches paper and fish. Also, the parchment lifts the cooked fillet out clean without sticking to the foil.

Even fillet thickness controls the cook. When fillets vary from 1 inch to 2 inches, the thin ends dry out before the thick centers reach 145F. Instead, buy center-cut fillets of similar thickness, or fold the thin tail under to even them out. A 145F check at the thickest point keeps every fillet safe and moist.

Rotation beats flipping for delicate fish. Therefore, turn each packet 90 degrees at the halfway mark instead of flipping it, which breaks the fillet apart. On a windy night, build a windbreak with a Fireside Outdoor pit or a row of rocks to hold the coals steady. Then the salmon cooks evenly and stays in one glossy piece.

Variations and Substitutions

• Honey garlic glaze: Swap teriyaki for a mix of honey, soy sauce, and extra garlic. The honey caramelizes into a sticky glaze on the coals.
• Spicy miso: Whisk 1 tablespoon white miso and 1 teaspoon sriracha into the sauce. Finish with extra scallion and a squeeze of lime.
• Maple soy: Replace teriyaki with maple syrup and soy sauce for a sweeter, Pacific Northwest glaze. Add a pinch of black pepper.
• Trout swap: Use trout fillets in place of salmon. Reduce the cook to 12 to 14 minutes, since trout is thinner.
• Add vegetables: Tuck snap peas, sliced bell pepper, or bok choy around the fillet. Keep them thin so they cook in the same time.
• Sesame crust: Press extra sesame seeds onto the fillet before sealing for a nutty, crunchy top after cooking.
• Scaled for 2 people: Halve every ingredient. Build 2 packets with 2 fillets.
• Scaled for 6 people: Increase all amounts by 50%. Build 6 packets and light 30 briquettes for a longer coal bed.

Storage and Leftovers

Raw salmon holds below 40F for 1 to 2 days before cooking. Specifically, the fillets keep in a sealed bag on ice, while the teriyaki sauce keeps a week in the cooler. Because raw fish spoils fast, never let the salmon bag sit above 40F for more than 2 hours, or 1 hour above 90F. Also, keep the salmon sealed and below the ready-to-eat food in the cooler.

Cooked foil packet teriyaki salmon holds below 40F for 2 days after cooking. Then reheat a sealed leftover packet on medium-low coals for 5 minutes, taking care not to dry out the fish. Otherwise, flake the cold salmon over rice or a salad for a no-reheat lunch. Discard any cooked packet left above 40F for more than 2 hours, per USDA safe handling rules.

Frequently Asked Questions

Why line foil packet teriyaki salmon with parchment?

Teriyaki sauce is acidic and salty, and it pits bare aluminum foil over a long cook. Specifically, the reaction leaves a metallic taste and small holes in the foil. Therefore, line each packet with parchment so the sauce touches only paper and fish. The parchment also lifts the cooked fillet out clean without sticking.

What internal temperature is safe for salmon?

Cook salmon to 145F at the thickest point. The USDA recommends 145F for fish, where the flesh turns opaque and flakes with a fork. Slide an instant-read thermometer into the center of the fillet to confirm. Because salmon dries out past 150F, pull the packet as soon as it reaches temperature.

What coal temperature works best for salmon?

Medium coals at 350F to 400F cook salmon gently. Specifically, this lower heat brings the fish to 145F without drying the edges or scorching the glaze. However, hot coals above 500F overcook salmon in minutes. Look for gray ash over orange embers, not bright glowing coals, before placing the packets.

Should I flip the salmon packet?

No, rotate the packet instead of flipping it. Because salmon breaks apart when turned, a flip leaves you with a shredded fillet. Instead, rotate each packet 90 degrees at the halfway mark to even out hot spots. The sealed packet cooks the top with trapped steam, so the fish finishes without a flip.

Is frozen salmon okay for foil packet teriyaki salmon?

Thaw frozen salmon fully before cooking. Since a frozen fillet cooks unevenly and weeps water into the glaze, thaw it in the cooler overnight or under cold water. Then pat it dry before saucing. Cook the thawed salmon within a day for the best texture and safety.

Is it smart to prep foil packet teriyaki salmon ahead of time?

Yes, prep the fillets and sauce up to a day ahead and store both below 40F. However, do not assemble the foil packets until dinner time at camp. Since a long soak in acidic teriyaki turns the salmon mushy, sauce it right before cooking. Build the packets fresh right before they go on the coals.

How many packets fit on one coal bed?

A 12-inch by 12-inch bed from 25 briquettes holds 4 packets. Meanwhile, 6 packets need 30 briquettes raked into a longer 18-inch by 12-inch bed. Also, leave an inch between packets so heat circulates around each one. Crowding the bed creates cold spots and uneven cooking.

How do I pack out the foil and parchment?

Let each packet cool, then fold the foil and parchment into a tight ball. Specifically, the bundle compacts small and fits inside a sealed zip bag or dry box. Because Leave No Trace requires packing out all foil and paper, never bury or burn the scraps. Also, sealing the seafood foil keeps odor and wildlife away from camp.
