Smoky & Buttery: Japanese Foil-Wrapped Grilled Enoki Mushrooms

Introduction

There is a distinct, mouthwatering magic found in Japanese Izakaya cuisine, and few dishes capture it as perfectly as Enoki Batayaki. This Japanese foil-wrapped grilled enoki mushroom recipe is a masterclass in simplicity, transforming humble ingredients into a savory, umami-packed side dish that steals the show. The technique of steaming the mushrooms inside a foil packet allows them to absorb the rich combination of soy sauce, sake, and butter, while the high heat of the grill infuses a subtle warmth that oven-baking simply cannot replicate.

When cooking this on an Arteflame grill, you gain a distinct advantage. The solid steel cooktop provides the perfect consistent heat required to steam the packet gently without burning the delicate bottoms of the mushrooms. Whether you are looking for the perfect accompaniment to a Wagyu steak or a standalone vegetarian delight, this dish offers an explosion of earthy flavors and a satisfyingly crisp-tender texture. It is elegant, effortless, and undeniably delicious.

Ingredients

The Essentials

• 2 packs of fresh Enoki mushrooms (approx. 7 oz or 200g)
• 2 tablespoons Sake (Japanese rice wine)
• 2 tablespoons Soy sauce (premium quality preferred)
• 1 tablespoon Unsalted butter (cut into small cubes)
• Salt and freshly ground black pepper (to taste)

Garnish

• 1 Lemon (cut into wedges)
• 2 Green onions or scallions (finely chopped)

Instructions

Step 1: Preparing the Mushrooms

1. Begin by removing the Enoki mushrooms from their packaging. Locate the firm root base at the bottom of the cluster.
2. Using a sharp knife, trim off approximately one inch from the bottom to remove the earthy root section, ensuring the stems remain connected enough to handle but separate easily.
3. Gently tease the mushroom strands apart into smaller, bite-sized bundles. Do not wash them under running water, as they act like sponges; simply wipe them clean with a damp paper towel if necessary.

Step 2: Constructing the Foil Packet

1. Tear off a large sheet of heavy-duty aluminum foil (about 12 inches long). If you are using thin foil, use a double layer to prevent tearing on the grill.
2. Place the separated Enoki mushrooms in the center of the foil sheet, piling them slightly high as they will cook down significantly.
3. Fold up the edges of the foil slightly to create a "bowl" shape that will hold the liquids you are about to add.

Step 3: Seasoning the Dish

1. Drizzle the sake evenly over the mushrooms to help with the steaming process and add sweetness.
2. Pour the soy sauce over the top, ensuring it seeps down into the bundles.
3. Season lightly with a pinch of salt and fresh cracked black pepper.
4. Top the mound with the cubes of unsalted butter. As the packet heats up, the butter will melt and emulsify with the soy and sake to create a rich sauce.

Step 4: Sealing and Grilling

1. Bring the long edges of the foil together over the mushrooms and fold them tightly to create a sealed tent. Fold the side ends in securely to trap all the steam and juices inside.
2. Preheat your Arteflame grill. Place the foil packet directly onto the flat steel cooktop (plancha surface) where the heat is medium-high.
3. Grill for approximately 15 to 20 minutes. You should hear the liquids simmering inside the packet. The mushrooms are done when they are tender and the sauce is bubbling.

Step 5: Serving

1. Carefully remove the packet from the grill using tongs—it will be very hot.
2. Open the foil carefully to avoid the escaping steam. Garnish immediately with fresh chopped green onions and a squeeze of lemon juice to cut through the richness.
3. Serve directly in the foil for a rustic presentation or transfer to a small dish.

Tips

To ensure your grilled Enoki mushrooms turn out perfectly every time, handling the main ingredient correctly is crucial. The most important rule is to never soak Enoki mushrooms in water. Because they are incredibly porous, they will absorb the liquid and become soggy rather than crisp-tender. A quick brush or a wipe with a damp cloth is all they need. Additionally, when creating your foil packet, ensure you leave a little bit of air space above the mushrooms inside the tent. This allows the steam to circulate effectively, cooking the mushrooms evenly from top to bottom.

If you are cooking on the Arteflame, utilize the different heat zones. Start the packet closer to the center to get the liquids boiling, then move it to the outer ring of the cooktop to simmer gently. This prevents the bottom layer of mushrooms from scorching before the butter has fully melted and marinated the upper layers. Finally, use unsalted butter so you can control the sodium level, as soy sauce already contributes significant saltiness.

Variations

While the traditional butter and soy sauce combination is a classic for a reason, Enoki mushrooms act as a blank canvas for a variety of flavor profiles. You can easily adapt this recipe to suit your dietary preferences or to match the main course you are serving. For those who enjoy a bit of heat, adding spice can transform the dish, while citrus lovers might prefer a tangier approach. Experimenting with different fats and aromatics can lead to surprising and delightful results.

• Spicy Kick: Sprinkle Shichimi Togarashi (Japanese seven-spice blend) or add a teaspoon of chili garlic paste (Sambal) into the packet before sealing.
• Garlic Lover’s: Add one teaspoon of minced fresh garlic or roasted garlic paste to the butter mixture for a pungent, aromatic depth.
• Citrus Ponzu: Substitute half of the soy sauce with Ponzu sauce for a lighter, citrus-forward flavor profile that pairs well with seafood.
• Vegan Option: Replace the butter with sesame oil or a high-quality vegan butter substitute to keep the dish entirely plant-based without losing richness.
• Herbal Twist: Add a sprig of fresh thyme or shiso leaves inside the foil packet for an aromatic herbal infusion that complements the earthy mushrooms.

Best pairings

Japanese foil-wrapped grilled Enoki mushrooms are incredibly versatile, serving as a robust side dish that complements a wide array of proteins. Their savory, umami-rich flavor profile creates a perfect counterpoint to rich, fatty meats. The salty, buttery sauce that forms in the foil packet is liquid gold, ideal for drizzling over rice or dipping other grilled items into. When planning your menu, think about textures; the slightly chewy, stringy texture of Enoki works best when paired with foods that offer a different mouthfeel, such as a tender steak or fluffy grains.

• Grilled Steak: The earthy flavors of the mushrooms stand up beautifully against a ribeye or Wagyu beef cooked on the Arteflame center grill grate.
• Seafood: Pair with grilled salmon or scallops; the lemon and butter in the mushrooms echo the flavors often used with fish.
• Steamed Rice: Serve alongside a bowl of short-grain white rice to soak up the excess soy-butter sauce.
• Yakitori: Serve as part of a larger Japanese BBQ spread alongside grilled chicken skewers and blistered shishito peppers.
