Preheat the oven to 400°F (200°C).
In a small bowl, mix the softened butter, minced garlic, chopped parsley, thyme leaves, salt, and pepper.
Drain the canned snails and rinse well.
Place a snail in each shell and fill the shell with the garlic butter mixture.
Place the filled shells on a baking sheet and bake for 10-15 minutes, until the butter is melted and bubbly.
Serve hot with crusty bread.
