Tips and Tricks
Choose the Right Mushrooms - Use similarly sized white or cremini mushrooms so they cook evenly and look uniform on the tray.Keep The Filling Thick - Let the garlic-stem mixture cool before mixing so the cream cheese stays thick and easy to spoon.Prevent Soggy Caps - Cook the chopped stems until dry; this removes moisture that can collect under the caps.Neat Filling - Use a small spoon or piping bag for tidy, level tops that won’t spill as they bake.Finish With Texture - For a light crunch, sprinkle a little extra grated Parmesan on top before baking.
