Recipe Overview

• Prep Time: 15 minutes
• Cook Time: 10-20 minutes (plus potentially up to 20 additional minutes, depending on your oven)
• Total Time: 25-35 minutes
• Servings: 4
• Dietary Type: Gluten-Free (when using tamari)

Ingredients

• 4 salmon fillets (skin on or off, your preference)
• 2 green onions, thinly sliced at an angle (feel free to double this, if you enjoy the flavor)
• 8 shiitake mushrooms, stems removed and tops cut in half
• Red pepper flakes, to garnish (optional)

For the Marinade:

• 3 tablespoons miso (preferably white or awase miso)
• 2 tablespoons mirin
• 2 tablespoons sake
• 2 teaspoons soy sauce (or reduced-sodium tamari for a gluten-free option)
• 1 tablespoon sugar

Equipment Needed

• Mixing bowl
• Shallow pan
• Aluminum foil

Instructions

1. Prepare the Marinade: In a mixing bowl, whisk together the miso, mirin, sake, soy sauce (or tamari), and sugar until well combined and smooth. Ensure the sugar is completely dissolved. This marinade is the key to infusing the salmon with its umami-rich flavor.
2. Prepare the Salmon: Cut the salmon fillets into bite-sized pieces. This helps the marinade penetrate more evenly and ensures quicker cooking.
3. Marinate the Salmon: Place the cut salmon in a shallow pan, then pour the miso marinade over the fish. Gently toss to coat the salmon pieces evenly. Let the salmon marinate for 10 minutes. This allows the flavors to meld and the salmon to absorb the delicious marinade.
4. Prepare the Vegetables: While the salmon is marinating, thinly slice the green onions at an angle. Remove the stems from the shiitake mushrooms and cut the tops in half.
5. Assemble the Foil Packets: Preheat your oven to 400 degrees F (200 degrees C). Cut four large sheets of aluminum foil, each large enough to create a sealed pouch around one portion of salmon and vegetables.
6. Layer the Ingredients: Place the ingredients on each sheet of aluminum foil in the following order: First, a layer of sliced green onions on the bottom. Next, arrange the marinated salmon pieces on top of the green onions. Finally, scatter the halved shiitake mushroom caps over the salmon.
7. Seal the Foil Packets: Carefully fold the sides and ends of the aluminum foil to create a sealed pouch. Ensure the seal is tight to prevent any juices from leaking out during cooking. This steams the salmon in its own flavorful broth, resulting in incredibly moist and tender fish.
8. Bake the Salmon: Place the foil packets in a baking pan and bake in the preheated oven for 10-20 minutes, or until the salmon is cooked through. Cooking times can vary depending on the thickness of the salmon fillets and your oven. Start checking for doneness at the 10-minute mark. The salmon is done when it flakes easily with a fork. (Note: Some ovens may require up to 20 additional minutes of cooking time. Use a fork to gently open a packet, check for doneness, and reseal if necessary.)
9. Garnish and Serve: Once the salmon is cooked through, carefully open the foil packets (be cautious of the steam!). Sprinkle with red pepper flakes (if desired) for a touch of heat and serve immediately.

Expert Tips & Tricks

• Miso Variety: Experiment with different types of miso. White miso (shiro miso) is the mildest and sweetest, while red miso (aka miso) has a bolder, more robust flavor. Awase miso is a blend of white and red miso, offering a balance of flavors.
• Marinating Time: While 10 minutes is sufficient, marinating the salmon for up to 30 minutes will intensify the flavor. Don’t marinate for much longer than that, though, as the acids in the marinade can start to break down the texture of the fish.
• Foil Quality: Use heavy-duty aluminum foil to prevent tearing during cooking.
• Doneness Check: Gently open one of the foil packets to check for doneness. The salmon should be opaque and flake easily with a fork. If it’s still translucent, reseal the packet and continue cooking for a few more minutes.
• Extra Flavor Boost: Add a thin slice of fresh ginger or a small knob of butter to each foil packet for an extra layer of flavor.
• Broiling Finish: For a slightly caramelized top, carefully open the foil packets during the last few minutes of cooking and broil for 1-2 minutes, watching closely to prevent burning.

Serving & Storage Suggestions

Serving: Serve the Foiled Miso Salmon immediately after cooking. The salmon is delicious served over a bed of steamed rice or alongside a simple salad. Garnish with extra sliced green onions or a sprinkle of sesame seeds for added visual appeal.

Storage: Leftover cooked salmon can be stored in an airtight container in the refrigerator for up to 2 days.

Reheating: Gently reheat the salmon in the microwave or in a covered skillet over low heat. Be careful not to overcook it, as this can dry it out. You can also enjoy it cold in salads or sandwiches.

FAQs (Frequently Asked Questions)

Q: Can I use frozen salmon for this recipe?
A: Yes, you can use frozen salmon. Thaw it completely before marinating. Pat it dry with paper towels to remove excess moisture before adding it to the marinade.

Q: Can I prepare the foil packets ahead of time?
A: You can assemble the foil packets up to a few hours in advance and store them in the refrigerator until ready to bake. Add some ice packs to the container in order to keep everything cold.

Q: What if I don’t have mirin or sake?
A: If you don’t have mirin, you can substitute it with a mixture of rice vinegar and a pinch of sugar. If you don’t have sake, you can use dry sherry or even a little bit of water.

Q: How do I know when the salmon is done?
A: The salmon is done when it flakes easily with a fork and is opaque throughout. The internal temperature should reach 145 degrees F (63 degrees C).

Q: Can I grill these foil packets instead of baking them?
A: Yes, you can grill the foil packets over medium heat for approximately the same amount of time as baking (10-20 minutes). Make sure the grill is covered.
