In a bowl, mix the softened butter, minced garlic, chopped parsley, minced shallots, lemon juice, salt, and pepper until well combined.
If using fresh escargots, clean them thoroughly.
If using canned escargots, drain and rinse them under cold water.
Place a small amount of garlic butter into each snail shell or each compartment of the snail baking dish.
Insert one escargot into each shell or compartment, then top with more garlic butter to fill the shell or compartment completely.
Preheat the oven to 375°F (190°C).
Place the prepared escargots on a baking sheet if using snail shells.
Bake for about 10-12 minutes, or until the garlic butter is bubbling and the escargots are heated through.
Enjoy your meal!
