It's actually a recipe I found online and though I don't get a chance to fix it very often, it is a nice change from the same ol' same ol'. I usually buy round steak when its part of a special meat sale at our grocery.
Round Steak Supreme
1 1/2 or 2 lbs round steak (top or bottom round- recipe calls of thicker, but I use the thin)
Large jar sliced mushrooms
1 envelope dry onion soup
1 envelope or beef bouillon
(You can also add fresh onion and green pepper, if desired)
Place Round Steak in a foil lined 13 X 9 casserole dish. Drain mushrooms and spread across the top of meat. (add onion and green pepper here if desired). Sprinkle with dry onion soup mix and beef bouillon. Save back packet from onion soup mix and add 2 packs of water. Wrap tightly with foil.
Bake at 350º for 2 hours. (says to serve with white or beef flavored rice. Purely optional. I fixed it with mashed potatoes and corn this time around)
