Crock Pot Cabbage Roll Casserole is a filling and hearty casserole full of ground beef, rice, and tomato sauce with melted mozzarella cheese on top. It has all the flavor of stuffed cabbage but is much easier to make.
Place a large nonstick pan over medium-high heat. Add ground beef, onion, and bell pepper. Crumble the beef. When there is almost no pink left, add garlic and cook for 1 minute.
Add diced tomatoes, half the tomato sauce, half the tomato soup, and all of the Worcestershire sauce, salt, pepper, thyme, and bouillon cube. Stir to mix.
Mix in the rice and remove from heat.
Transfer half of the meat mixture to a 6-quart slow cooker. Layer half the cabbage on top. Repeat layers.
Mix the remaining tomato sauce and tomato soup together with the water. Pour over cabbage.
Place lid on crock pot and set to cook on LOW for 5 hours.
Remove lid and sprinkle cheese on top. Place lid back on for 10 minutes to melt the cheese.
