Easy Cabbage Roll Casserole (Slow Cooker)

Cabbage rolls are a classic comfort food, but rolling each leaf by hand takes time and patience. This slow cooker cabbage roll casserole keeps all the savory flavor of the traditional dish and skips the rolling entirely. Seasoned ground beef, chopped cabbage, rice, and tomato sauce cook together until everything is tender, making it an easy dinner for busy weeknights.

Why You’ll Love This Recipe

• No rolling required: Everything is layered in one pot, so there are no leaves to fill and wrap.
• Hands-off cooking: The slow cooker does the work while you handle the rest of your day.
• Simple ingredients: Most of the items are pantry staples plus a head of cabbage and an onion.
• Easy cleanup: You only need a skillet, a cutting board, and the slow cooker.
• Good for leftovers: It reheats well for lunches the next day.

Ingredients

• 1 lb (450 g) lean ground beef
• 1 small yellow onion, diced
• 3 cloves garlic, minced
• 1 small head green cabbage (about 2 lb / 900 g), cored and chopped into bite-size pieces
• 3/4 cup (140 g) uncooked long-grain white rice
• 1 can (15 oz / 425 g) tomato sauce
• 1 can (14.5 oz / 411 g) diced tomatoes, undrained
• 1 1/2 cups (360 ml) low-sodium beef broth
• 1 tsp (6 g) salt
• 1/2 tsp (1 g) black pepper
• 1 tsp (2 g) paprika
• 1 tsp (5 ml) Worcestershire sauce (optional)

Ingredient Notes

Lean ground beef gives the filling rich flavor without leaving too much grease in the slow cooker. Long-grain white rice holds its shape well and absorbs the tomato liquid. Green cabbage is sturdy enough to stay tender without falling apart, so it is the best choice here. You can swap ground turkey for beef, but choose a fattier blend or add a little extra seasoning, since turkey tends to be milder.

Equipment You’ll Need

• A 6-quart slow cooker
• A large skillet
• A cutting board and sharp knife
• A wooden spoon or spatula

How to Make Slow Cooker Cabbage Roll Casserole

1. Brown the beef. Heat a large skillet over medium-high heat. Add the ground beef and break it up with a spoon. Cook for 6 to 8 minutes, until no pink remains and the internal temperature reaches 160°F (71°C). Drain any excess fat.
2. Cook the aromatics. Add the diced onion to the same skillet and cook for 3 to 4 minutes, until softened and translucent. Stir in the garlic for 30 seconds, until fragrant.
3. Prepare the cabbage. Cut the cabbage into bite-size pieces, about 1 inch (2.5 cm) wide. The pieces should look like rough squares, not thin shreds.
4. Layer the slow cooker. Spread half the cabbage across the bottom of the slow cooker. Spoon half the beef mixture over the cabbage, then sprinkle with half the uncooked rice. Repeat with the remaining cabbage, beef, and rice.
5. Add the sauce. In a bowl, stir together the tomato sauce, diced tomatoes, beef broth, salt, pepper, paprika, and Worcestershire sauce. Pour the mixture evenly over the layers. The cabbage should be mostly covered by liquid, but it will shrink as it cooks.
6. Cook low and slow. Cover and cook on LOW for 6 to 7 hours, or on HIGH for 3 to 4 hours. The casserole is done when the cabbage is very soft, the rice is tender and no longer crunchy, and the sauce is bubbling around the edges.
7. Stir and serve. Gently stir the layers together so the rice, cabbage, and beef are evenly mixed. If the mixture looks too thick, add a splash of broth. Taste and adjust the salt before serving.

Pro Tips for the Best Results

• Cut the cabbage into even pieces so they cook at the same rate.
• Drain the beef well to keep the casserole from tasting greasy.
• Check the rice near the end of cooking. If it is still firm, cover and cook for another 30 minutes on LOW.
• Use low-sodium broth, since canned tomato products already add salt.
• Taste before serving and adjust the seasoning, because slow cooker flavors can mellow over long cooking.

Common Mistakes to Avoid

• Skipping the browning step: Cooking raw ground beef in the slow cooker can leave it gray and greasy. Browning first adds flavor and helps drain the fat.
• Too little liquid: Uncooked rice needs enough liquid to become tender. Make sure the sauce covers the layers before you put the lid on.
• Lifting the lid too often: Each time you open the slow cooker, heat escapes and the cooking time increases.

Variations and Substitutions

• Ground turkey: Use ground turkey in place of beef and add a little extra garlic or paprika.
• Cauliflower rice: For a lower-carb option, replace the white rice with cauliflower rice added during the last 30 minutes of cooking.
• Smoky flavor: Add 1/2 tsp smoked paprika for a deeper, smoky taste.
• Spicy version: Stir in a pinch of red pepper flakes or use a can of diced tomatoes with green chiles.

Serving Suggestions

Serve the casserole in deep bowls with a spoonful of sour cream and a sprinkle of fresh chopped parsley. A slice of crusty bread or a simple green salad makes a satisfying side. Warm dinner rolls are also a good match for the tomato sauce.

Storage and Reheating

Let the casserole cool for no more than 2 hours, then transfer it to airtight containers. Refrigerate for up to 3 to 4 days. To freeze, portion the casserole into freezer-safe containers and keep it frozen for up to 3 months. Reheat leftovers in the microwave or on the stovetop over medium heat, stirring occasionally, until steaming hot throughout. Add a splash of broth if the rice has absorbed too much liquid.

Frequently Asked Questions

Can I make this casserole ahead of time?

Yes. You can brown the beef and chop the cabbage up to one day ahead and store them separately in the refrigerator. Assemble and cook the casserole on the day you plan to eat it.

Can I freeze cabbage roll casserole?

Yes. Cool the casserole completely, then freeze it in portions for up to 3 months. Thaw in the refrigerator overnight before reheating.

Why is my casserole watery?

Cabbage releases water as it cooks. If the sauce seems thin, cook uncovered on HIGH for 20 to 30 minutes at the end, or use a little less broth next time.

Can I use white rice instead of long-grain rice?

Yes, long-grain white rice is the best choice. Short-grain rice can become sticky, and brown rice needs more liquid and a longer cooking time.

Can I make this recipe without a slow cooker?

You can bake it in a covered Dutch oven at 350°F (175°C) for about 1 hour to 1 hour 15 minutes, until the rice and cabbage are tender. Check the rice for doneness before serving.

Do I need to pre-cook the rice?

No. The uncooked rice cooks directly in the sauce, so the dish only needs to be layered and set to cook.
