Tips
Pat mushrooms thoroughly dry to prevent excess moisture during cooking.
Watch closely during grilling as cooking time varies by grill intensity and mushroom thickness.
Brush garlic oil on the underside where it absorbs best and won't burn.
Good to Know
Assemble just before grilling; cooked pizzas store in airtight container up to 2 days, reheat gently.
Wash and stem mushrooms, mince garlic, and slice tomatoes up to 4 hours ahead. Refrigerate components separately.
Serve immediately while cheese is melted and mushroom is warm. Pair with fresh greens or crusty bread.
Common Mistakes
Don't skip patting mushrooms dry to avoid soggy, watery caps.
Don't overload toppings to prevent uneven cooking and excess moisture release.
Don't grill at low heat to avoid tough, shriveled mushrooms instead of tender and golden.
