In a small bowl, blend together butter, oil, garlic, salt and pepper.

Spread over all surfaces of steak.

In another bowl, combine croutons and cheese, stirring to blend.

Press cheese mixture onto surface of steak.

Place steak in a brown paper bag.

Fold up open end and secure tightly with staples or paper clips.

Place bag on a rimmed cookie sheet (to catch juice of steak which will run out during cooking).

Place cookie sheet in preheated 350° oven.

Bake until desired doneness. Approximately 45 minutes for medium rare for example.
