@spumoni99 Cook the chicken fried steak (but do not tenderize it) on top of the stove. After it is cooked, let it rest on a plate or platter to allow it to settle and some of the grease drain away from it. Then place the cooked steak into a casserole or Pyrex dish that is oven safe.
Mix the buillion in the water. Drain almost all of the grease from the skillet. Leave the crumbles from the steak. Add flour to the grease using a whisk or dinner fork to keep it from getting lumpy. The ratio is the grease will disappear into the flour. Do not leave any exposed grease. Add flour slowly until this happens. Stir in the buillion mixture and more water to get the consistency of gravy that is a bit more runny than how you would serve it alone. Don't get it too thick. Cover the steak with the gravy. I use a Corningware casserole that has a fitted lid and put the lid on the casserole. Foil would work on Pyrex.
In my family a slow oven is about 275-300 depending on the quirks of the oven. Cook for 3 hours. The meat will tenderize itself during the slow cooking. The flour from the gravy will thicken it more.
If you have Kitchen Bouquet add it into the buillion water. I usually stir it into that to be sure it is dispersed evenly. This is an easy meal that affords an opportunity to clean up the chicken fried steak mess and relax before dinner. We like to have mashed potatoes with it.
Enjoy! I hope you like it with or without Kitchen Bouquet.
By the way, I have the butcher tenderize my round steak that I eat as chicken fried steak. Tenderized steak in this casserole doesn't work as well as the undisturbed beef. Finding round steak is sometimes a challenge. Finding a whole one with the bone verges into unicorn territory.
