Preheat the oven to 375°F (190°C).
Clean the mushrooms and remove the stems.
Finely chop the mushroom stems and sauté with garlic in olive oil for 3-4 minutes.
In a bowl, mix the sautéed stems, crab meat, cream cheese, Parmesan, breadcrumbs, parsley, lemon juice, salt, and pepper.
Spoon the crab mixture into each mushroom cap, filling generously.
Place the stuffed mushrooms on a baking sheet lined with parchment paper.
Drizzle lightly with olive oil and season with salt and pepper.
Bake for 20-25 minutes until golden brown and heated through.
Garnish with extra parsley before serving.
