Introduction
Slow Cooker Unstuffed Cabbage Roll Casserole gives you all the comforting flavors of traditional stuffed cabbage rolls without the work of individually rolling cabbage leaves. Tender cabbage cooks slowly with seasoned ground beef, rice, onions, garlic, and tomatoes in a rich savory tomato sauce.
It is a hearty one-pot family dinner that uses simple ingredients and works especially well for busy weeknights.
Why This Recipe Is Popular
Traditional cabbage rolls are delicious, but preparing and rolling every cabbage leaf takes time. This slow cooker version keeps the familiar combination of cabbage, beef, rice, and tomatoes while making preparation much easier.
The cabbage becomes tender as it absorbs the tomato and beef flavors, while the rice helps turn everything into a thick, satisfying casserole.

Main Ingredients
Green cabbage: The main vegetable becomes tender and slightly sweet after slow cooking.
Ground beef: Provides the rich, savory base of the casserole.
Rice: Long-grain white rice works well and absorbs the seasoned tomato broth.

Tomato sauce: Creates a richer sauce that coats the beef, cabbage, and rice.
Onion and garlic: Essential aromatics that deepen the flavor.
Ingredients
1 1/2 pounds lean ground beef
1 medium yellow onion, diced
3 cloves garlic, minced
1 medium head green cabbage, roughly chopped
1 can (14.5 ounces) diced tomatoes
1 can (15 ounces) tomato sauce
1 1/2 cups beef broth
3/4 cup uncooked long-grain white rice, rinsed
1 tablespoon Worcestershire sauce
1 teaspoon paprika
1 teaspoon Italian seasoning
1/2 teaspoon dried thyme
1 teaspoon garlic powder
1/2 teaspoon onion powder
1 teaspoon salt, or to taste
1/2 teaspoon black pepper
1/4 teaspoon crushed red pepper flakes, optional
2 tablespoons chopped fresh parsley
How to Choose the Best Ingredients
Choose a fresh, firm green cabbage with tightly packed leaves. Remove any damaged outer leaves before cutting.
Lean ground beef works best because it provides plenty of flavor without making the casserole excessively greasy.
Use regular long-grain white rice rather than instant rice. Rinse it briefly under cold water before adding it.
For the tomatoes, regular diced tomatoes work perfectly, although fire-roasted tomatoes can add a deeper flavor.
Prepare the Ground Beef
Heat a skillet over medium-high heat.
Add the ground beef and diced onion.
Cook until the beef is browned and broken into small crumbles.
Add the minced garlic during the final minute.
Drain excess grease before transferring the mixture to the slow cooker.
Prepare the Cabbage
Remove the tough outer leaves.
Cut the cabbage into quarters and remove the hard center core.
Cut the leaves into fairly large pieces.
Do not shred them too finely because cabbage shrinks considerably as it cooks.
Prepare the Other Ingredients
Rinse the rice until the water runs mostly clear.
Combine the diced tomatoes, tomato sauce, beef broth, Worcestershire sauce, paprika, Italian seasoning, thyme, garlic powder, onion powder, salt, and pepper.
Having the tomato mixture ready helps distribute the seasonings throughout the casserole.
Step-by-Step Instructions
Place approximately half of the chopped cabbage in the bottom of the slow cooker.
Spread half of the browned beef and onion mixture over the cabbage.
Sprinkle approximately half of the rinsed rice over the beef.
Add some of the tomato mixture.
Repeat the layers with the remaining cabbage, ground beef, rice, and tomatoes.
Pour the remaining seasoned tomato sauce and beef broth evenly over everything.
Gently press the ingredients down so the rice has adequate contact with the liquid. Avoid aggressively stirring everything together.
Cover the slow cooker.
Cook on LOW for approximately 5–6 hours, checking toward the end for rice and cabbage tenderness.
Gently stir once the rice is completely cooked.
Taste and adjust the seasoning.
Finish with fresh parsley and serve hot.
Tips for Best Results
Brown the beef first. This improves its texture and prevents excessive grease from collecting in the slow cooker.
Keep the cabbage pieces fairly large because they shrink substantially.
Make sure the rice has enough liquid around it to cook properly.
Do not repeatedly remove the lid. Each time the slow cooker is opened, heat escapes and cooking takes longer.
Different slow cookers heat differently, so check the rice before serving. It should be completely tender.
If the casserole looks too thick near the end, add a small splash of hot beef broth.
Flavor Variations
For a slightly sweeter traditional cabbage-roll flavor, add one tablespoon of brown sugar to the tomato sauce.
For extra heat, add red pepper flakes or cayenne.
Ground turkey can replace the ground beef.
You can also use a mixture of ground beef and ground pork for a richer traditional flavor.
For additional vegetables, add diced carrots, bell peppers, or celery.
A little shredded cheddar or mozzarella can also be melted over individual servings for a cheesy variation.
How to Serve
Serve the casserole hot in deep bowls with plenty of cabbage, beef, rice, and tomato sauce in every portion.
It pairs beautifully with crusty bread, garlic bread, dinner rolls, or cornbread.
A spoonful of sour cream on top is also delicious and adds a cool, creamy contrast to the tomato sauce.
Meal Prep and Storage
Allow leftovers to cool before transferring them to airtight containers.
Refrigerate for up to 3–4 days.
The casserole often becomes thicker overnight because the rice continues absorbing some of the sauce.
When reheating, add a splash of beef broth or tomato sauce if necessary.
Individual servings can be reheated in the microwave, while larger quantities can be gently reheated on the stovetop.
Common Mistakes to Avoid
Do not finely shred the cabbage or it may become too soft.
Avoid adding uncooked ground beef as one large mass. Browning and crumbling it beforehand gives the casserole a much better texture.
Do not reduce the cooking liquid too aggressively because uncooked rice needs enough moisture.
Avoid using instant rice with the same cooking time because it can become mushy.
Most importantly, check that the rice is completely tender before serving.
Frequently Asked Questions
Can I make this without rice?
Yes. Leave out the rice and reduce the amount of broth since there will be nothing to absorb the extra liquid.
Can I use ground turkey?
Yes. Ground turkey is an easy substitute for ground beef.
Can I use brown rice?
Brown rice requires considerably longer cooking and more liquid, so white long-grain rice is easier and more predictable for this recipe.
Can I add cheese?
Yes. Sprinkle cheddar or mozzarella over the finished casserole and cover briefly until melted.
Can I make it spicy?
Absolutely. Add crushed red pepper flakes, cayenne, or your favorite hot sauce.
How do I know when it is ready?
The cabbage should be tender, the rice fully cooked, and the ground beef mixture hot throughout.
