Brown pork steaks on both sides in hot shortening in a large skillet; drain steaks, reserving pan drippings in skillet. Sprinkle steaks on both sides with salt and pepper. Set aside.
Add rice to pan drippings; cook over medium heat 10 minutes or until lightly browned, stirring constantly. Add chicken broth, onion, and poultry seasoning to rice; stir well. Pour rice mixture into a well-greased 3-quart casserole; place pork steaks on top of rice mixture. Cover and bake at 350° for 1 hour and 20 minutes or until liquid is absorbed. Serve hot.
