The only way I ever knew how to cook cubed steak was to season/flour/fry. It's tasty but tough. I recently found a recipe to oven bake with gravy for about a half hour. Easy, tasty, but still not tender and it's missing that flavor you get from frying. This is perfect! You quickly brown them, then finish them off in the oven. Low and slow and VERY tender in the end. The one thing I would do differently next time is I would cover with aluminum foil in the oven. I didn't do that and the gravy reduced to a sauce.
