Heat oil in a large nonstick skillet over medium-high. Add chopped mushroom stems, garlic, salt and pepper; cook, stirring often, until mushrooms soften and turn golden brown and moisture has evaporated, about 6 minutes. Add 1/4 cup of the panko; cook, stirring often, until panko is light golden, about 1 minute. Add cream cheese, parsley, thyme and 2 tablespoons of the Parmesan; remove from heat, and stir until combined.
