1-First Step: Prep the Mushrooms Clean mushrooms gently with a damp cloth or paper towel to remove any dirt. Slice the mushrooms in halves or thirds, depending on their size, to retain juiciness and ensure even cooking.

2-Second Step: Prepare the Garlic Butter In a bowl, gently melt butter over low heat. Add half of the minced garlic along with salt, black pepper, garlic salt, and chopped parsley. Whisk together to blend the flavors for a rich garlic butter sauce.

3-Third Step: Marinate the Mushrooms (Optional) If using, combine mushrooms in a large bowl with balsamic vinegar, soy sauce, and the remaining minced garlic. Let them marinate for about 30 minutes to infuse deeper flavors.

4-Fourth Step: Toss Mushrooms with Garlic Butter Drain mushrooms if marinated, then pour the garlic butter mixture over the mushrooms. Toss thoroughly to coat each piece evenly with the flavorful butter sauce.

5-Fifth Step: Prepare the Grill Preheat your grill to medium heat, approximately 350°F (175°C). Use a grill basket or heavy-duty foil to prevent mushrooms from falling through the grates.

6-Sixth Step: Grill the Mushrooms Spread the mushrooms evenly in the foil packet or basket. Grill for 15 minutes, then carefully flip and continue cooking for an additional 10 to 15 minutes until the mushrooms are tender and slightly caramelized.

7-Final Step: Serve and Garnish Remove the mushrooms from the grill and let sit for a few minutes. Sprinkle with extra garlic salt to taste if desired and garnish with fresh parsley. Serve warm as a delicious side dish or a satisfying snack.
