Heat olive oil in a large pan over medium heat. Add the mushrooms and sauté 5-6 minutes, stirring occasionally. Add garlic, thyme, salt and black pepper and sauté for another 1-2 minutes.

To a baking dish, combine the sautéed mushrooms, softened cream cheese, half of the mozzarella cheese, parmesan cheese and Worcestershire sauce. Mix until the mushrooms and cheese are fully incorporated into the cream cheese.

Smooth the dip into an even layer in the baking dish. Top the dip with remaining mozzarella cheese and breadcrumbs.

Bake the dip in a 350°F oven for 25-30 minutes, or until golden brown and bubbly.
