These Garlic Butter Grilled Mushrooms are a savory and aromatic side dish perfect for any barbecue or meal. Fresh mushrooms are coated with a flavorful garlic butter mixture, sealed in parchment to lock in juices, and grilled to tender perfection, resulting in a rich, buttery bite with just the right amount of garlic and herb freshness.

  • Total Time: 35 minutes
  • Yield: 3 servings

Ingredients

Mushrooms

  • 1 lb mushrooms (white button, bellas, or similar varieties)

Garlic Butter Sauce

  • 1/4 cup butter (melted)
  • 4 cloves garlic (minced)
  • 1/2 tsp salt
  • 1/2 tsp pepper
  • 1 tsp garlic salt (plus more for sprinkling)
  • 1-2 tbsp chopped fresh parsley

Instructions

  1. Preheat Grill: Preheat your grill to 350°F to ensure it reaches the ideal temperature for even cooking of the mushrooms.
  2. Prepare Mushrooms: Slice the mushrooms into halves or thirds depending on their size, then transfer them into a large mixing bowl to prepare for coating.
  3. Make Garlic Butter Sauce: In a separate bowl, whisk together the melted butter, minced garlic, salt, pepper, garlic salt, and chopped parsley until fully combined and fragrant.
  4. Coat Mushrooms: Pour the garlic butter mixture over the sliced mushrooms and toss thoroughly to ensure each piece is evenly coated with the flavorful sauce.
  5. Wrap Mushrooms: Lay a large sheet of heavy-duty parchment paper on a flat surface and pour the coated mushrooms into the center. Bring the two long sides of the parchment together and fold down a few times to create a seal.
  6. Seal Edges: Roll up the edges of the parchment tightly to form a sealed packet that will trap the mushroom juices while grilling and prevent any leakage.
  7. Grill Mushrooms: Place the sealed parchment packet on the preheated grill. Cook for 15 minutes, then carefully turn the packet and grill for an additional 10-15 minutes, allowing the mushrooms to steam in their own juices.
  8. Serve: Remove the packet from the grill and let it sit for a few minutes. Serve the mushrooms directly in the parchment or transfer to a bowl. Sprinkle additional garlic salt to taste if desired.

Notes

  • You can use any variety of mushrooms such as cremini or portobello for slightly different textures and flavors.
  • Ensure the parchment paper is tightly sealed to keep moisture from escaping and to steam the mushrooms effectively on the grill.
  • If you don’t have fresh parsley, dried parsley can be substituted but use less as dried herbs are more concentrated.
  • This recipe can be easily doubled or tripled depending on the number of servings needed.
  • For a vegan version, substitute butter with a plant-based butter alternative.
  • Keep an eye on the grill temperature to avoid burning the parchment; 350°F is ideal to gently cook the mushrooms without charring.
