Clean the mushrooms by briefly rinsing and gently wiping them with paper towels.
Combine the butter, olive oil, and garlic in a small saucepan; whisk in the balsamic vinegar and thyme and cook over medium-low heat for 2 to 3 minutes, until aromatic. Taste and add salt and pepper as desired.
Prepare the grill for medium-high heat.
Brush the mushrooms all over with some of the sauce mixture.
Grill the mushrooms, gill-sides down, for 4 minutes, basting again about halfway through. Flip, baste again with the sauce mixture, and grill for another 5 to 6 minutes or until tender.
