Fire up your pellet grill—today we’re making a flavorful Traeger Lion’s Mane mushroom recipe. Lion’s Mane is becoming easier to find in grocery stores during its season, but many cooks need inspiration for how to prepare it. This recipe highlights the mushroom’s natural sweetness and meaty texture by roasting it over a wood-fired pellet grill and finishing with a bright, slightly sweet balsamic glaze.

Traeger Grilled Lion’s Mane Mushroom Recipe
We love a standout side dish, and this grilled Lion’s Mane quickly became a favorite. The mushroom pairs beautifully with smoke and light char—simply coat with olive oil, season with a herby rub, roast on the Traeger until tender, and finish with a sweet-and-tangy balsamic reduction. The result is an elegant vegetarian side that can stand up to robust mains or serve as a centerpiece for a meatless meal.
Lion’s Mane is known for its unique appearance and pleasing texture. Its mild, slightly sweet flavor is sometimes likened to seafood, which makes it a popular choice for vegetarian dishes that want a rich, savory character. When cooked, the mushroom’s delicate spines crisp up on the outside while the interior stays tender and slightly chewy, giving a pleasing contrast in every bite.

How to Make This Recipe
The summary below gives an overview of the cooking process. Follow the full instructions in the recipe card for best results.
- Preheat – Preheat your pellet grill to 350°F (175°C).
- Prep – Clean the mushroom gently and cut into large chunks or tear into portions. Place on a lightly oiled baking sheet. Drizzle with olive oil and season with your herby rub and a pinch of salt.
- Roast – Roast on the grill for 20–25 minutes, flipping once about halfway through, until edges are golden and the interior is tender.
- Make the glaze – While the mushrooms roast, combine balsamic vinegar, brown sugar, minced garlic, and a touch of sriracha in a small saucepan. Simmer gently until the mixture reduces and thickens into a syrupy glaze, about 5–6 minutes. Stir frequently to prevent scorching.

- Serve – Serve hot as a side dish or use as a meaty component in sandwiches, salads, or plated mains.

Traeger Lion’s Mane Mushrooms
Fresh Lion’s Mane mushrooms are roasted on the grill and finished with a balsamic glaze, creating a savory, slightly sweet side dish that mushroom lovers will enjoy.
Ingredients
- 2 pounds Lion’s Mane mushrooms
- 2 tablespoons olive oil
- 1 tablespoon herby rub (such as a Sasquatch Moss-style blend)
- ½ teaspoon salt
Balsamic glaze
- ½ cup balsamic vinegar
- 3 tablespoons brown sugar
- 2 cloves garlic, minced
- ½ teaspoon sriracha (optional)
Instructions
- Preheat your pellet grill to 350°F (175°C).
- Clean the mushrooms gently with a brush or damp cloth to remove dirt. Cut into large chunks or tear into pieces and arrange on a lightly oiled baking sheet.
- Drizzle with olive oil and sprinkle with the herby rub and salt so each piece is lightly coated.
- Place the baking sheet on the grill and roast for about 20–25 minutes. Flip the pieces once about 10 minutes in so both sides get even color and a bit of char.
- While the mushrooms roast, make the balsamic glaze: combine balsamic vinegar, brown sugar, minced garlic, and sriracha (if using) in a small saucepan. Bring to a gentle simmer, stirring frequently, and reduce until slightly thickened—about 5–6 minutes. Remove from heat and let cool slightly; it will thicken as it cools.
- When the mushrooms are done, transfer them to a serving dish and drizzle with the balsamic reduction. Toss gently to coat or spoon the glaze over each piece.
- Serve immediately while warm. Leftovers keep well in an airtight container for a day or two and can be reheated gently.
