If steak is not in individual pieces - cut the steak
*optional, but a good idea - Use a mallet to pound both sides of the steak - just enough to break up the muscle
pour a scant amount of flour on a plate
sprinkle about half of your salt and pepper on the flour and mix in with a fork
use tongs to coat the steak on both sides with flour
melt butter in a large skillet over medium-high heat
brown steak on both sides
place steak in a 9x13 inch pan
add the mushrooms to the skillet and cook them until tender - about one 1-minute longer
place mushrooms, scrapings, and any juice from the pan over the steaks
Add water until it is about 1/4 inch deep in the pan
place bay leaves in the water
shake onion soup mix, plus the rest of your salt, and pepper over the steaks and into the water
cover with foil
bake at 325 degrees for 1&1/2 hours or until tender
