We've turned this extravagant entr̩ee into a bite-sized appetizer. Mushroom duxelle, made with heavy cream, shallots, and sherry, join tender bites of filet mignon that finish off medium rare after baking. This sumptuous creation is housed in buttery, flaky puff pastry, for the perfect dinner party finger food.
Do not defrost. Preheat oven to 425° F. Place wellingtons on a lightly sprayed baking sheet. Bake for 12-18 minutes. Oven temperatures vary; adjust accordingly.
