2 lb beef round steak about 3/4-inch thick
1/4 cup flour
1/2 tsp salt
couple dashes black pepper
2 tbsp canola oil
1 medium to large yellow onion, sliced
1 can (10 3/4-oz) condensed cream of celery soup, undiluted
1/2 tsp dried oregano
1/4 tsp dried thyme
1/3 cup cold water
3 tbsp flour
Trim any excess fat from the round steak and cut steak into 6 equal portions. Coat meat in the 1/4 cup of flour; pound gently with a meat mallet. Sprinkle the meat with the salt and pepper.
Heat canola oil in a large skillet over medium-high heat. Brown the meat, on both sides, in the skillet. Remove meat from the skillet and place in slow cooker or crockpot. Discard the drippings from skillet, reserving about a tablespoonful.
Cook the onion in the reserved drippings in the skillet; stir in the celery soup, oregano, and thyme to blend well. Pour the soup mixture over the meat in the cooker. Place the cover on the cooker and cook on low setting for 8 to 10 hours.
Measure out 1 1/2 cups of the cooking liquid and place into a saucepan. Blend the cold water slowly into the 3 tablespoons of flour; stir into liquid. Cook, stirring, until thickened and bubbly. Season, if needed. Serve over the steak pieces.
