Sweet and Sour Beef Cubes

Ingredients

• 1/2 cup all-purpose flour, or as needed
• 1 (3 pound) beef chuck steak, cut into 1 1/2-inch cubes
• 3 onions, thinly sliced
• 3/4 cup water
• 3/4 cup ketchup
• 1/4 cup soy sauce
• 2 tablespoons vinegar
• 1 1/2 tablespoons Worcestershire sauce
• 1/2 pinch white sugar

Directions

Preheat oven to 250 degrees F (120 degrees C).

Put flour into a large, sealable plastic bag; add beef cubes and seal bag. Shake bag to coat beef in flour; transfer beef to a large casserole dish.

Top beef with sliced onions.

Whisk water, ketchup, soy sauce, vinegar, Worcestershire sauce, and sugar together in a bowl; pour over the onion slices. Cover the dish with aluminum foil.

Bake in preheated oven until the beef is tender enough to pull apart with a fork, about 3 hours.
