- 1 small yellow onion, finely diced
- 2 garlic cloves, finely grated into a smooth paste
- 1 teaspoon Italian seasoning
- ¼ teaspoon freshly ground black pepper

Instructions
1. Prepare and Soften the Cabbage Leaves
Start by preparing the cabbage. Remove any damaged, loose, or discolored outer leaves and rinse the cabbage thoroughly under cold running water.
Place the cabbage on a cutting board with the stem facing upward.
Using a sharp knife, carefully cut around the core and remove as much of the hard central core as possible without cutting through the surrounding leaves.
Fill a large pot with water and bring it to a gentle boil over medium-high heat.
Carefully lower the whole cabbage head into the boiling water, with the core opening facing downward.
Allow it to cook for approximately 2–3 minutes. As the outer leaves soften, use kitchen tongs to gently peel them away from the cabbage.
Transfer each softened leaf to a large plate or tray.
Continue this process until you have eight large cabbage leaves suitable for rolling.
If the inner leaves remain too firm, return the cabbage to the boiling water for another 1–2 minutes before removing additional leaves.
Once all eight leaves are ready, allow them to cool enough to handle safely.
Place each leaf flat on a cutting board. Using a small sharp knife, carefully shave down the thick central rib, making it thinner and more flexible.
Be careful not to cut completely through the leaf.
This step is important because the thick rib can make folding difficult and may cause the cabbage to tear during rolling.
Pat the leaves dry with paper towels and set aside.
2. Prepare the Italian Sausage and Rice Filling
In a large mixing bowl, add the raw Italian pork sausage with the casings removed.
Break the sausage into smaller pieces using a fork or clean hands.
Add the completely cooled cooked white rice.
Next, add the finely diced onion and freshly grated garlic paste.
Sprinkle in the Italian seasoning and black pepper.
Using clean hands or a sturdy spoon, gently combine all the ingredients until evenly distributed.
Avoid overmixing or compressing the filling too tightly. You want the mixture to remain tender rather than becoming dense.
Taste only the seasoning separately if needed; do not taste the raw sausage mixture.
Because Italian sausage is already seasoned and may contain a significant amount of salt, additional salt should be used sparingly or omitted entirely.
The finished filling should hold together when gently pressed but should not feel overly compact.
3. Prepare the Mozzarella Centers
Place the shredded low-moisture mozzarella in a small bowl.
Divide the sausage and rice mixture into eight approximately equal portions.
Each portion will become the filling for one cabbage roll.
Keep the mozzarella separate until you begin assembling the rolls.
For each portion, gently flatten the sausage mixture into an oval shape.
Create a small indentation in the center and place approximately 1 tablespoon of shredded mozzarella inside.
Carefully cover the mozzarella with a little more sausage mixture, making sure the cheese is completely surrounded.
Gently shape the filling into a compact oval.
This technique helps keep the mozzarella in the center while the sausage cooks and the cheese melts.
Avoid leaving exposed cheese on the outside of the filling, as it may escape into the marinara sauce during cooking.
Repeat until you have eight evenly filled portions.
4. Assemble the Cabbage Rolls
Place one softened cabbage leaf on a clean cutting board with the stem end facing toward you.
Position one portion of the sausage and rice filling near the lower center of the leaf.
Make sure the filling is positioned far enough from the edges to allow the cabbage to fold around it completely.
Lift the bottom edge of the cabbage leaf and fold it over the filling.
Fold the left and right sides inward to enclose the filling.
Continue rolling the cabbage forward, keeping the filling snugly enclosed.
The finished cabbage roll should be firm enough to hold its shape but not rolled so tightly that the cabbage splits.
Check both ends to make sure the filling and mozzarella center are completely covered.
If a leaf has a small tear, you can use a smaller piece of softened cabbage leaf to reinforce the area.
Repeat the process with the remaining seven cabbage leaves and filling portions.
You should now have eight large, evenly shaped cabbage rolls.
5. Prepare the Slow Cooker
Lightly grease the inside of a 6-quart slow cooker with cooking spray or a thin coating of olive oil.
Spread a small amount of marinara sauce across the bottom of the slow cooker.
This creates a flavorful base and helps prevent the cabbage rolls from sticking.
Carefully arrange the eight cabbage rolls inside the slow cooker.
Place them seam-side down so they remain closed during cooking.
Arrange them snugly in a single layer whenever possible.
If necessary, position the rolls close together without crushing them.
Pour the remaining marinara sauce evenly over the cabbage rolls.
Use a spoon to distribute some of the sauce into the spaces between the rolls.
Make sure the tops and sides are generously coated.
Do not add loose raw sausage, extra rice, or additional mozzarella directly into the sauce. Keep the prepared filling enclosed inside the cabbage leaves.
6. Slow Cook the Cabbage Rolls
Place the lid securely on the slow cooker.
Set the temperature to LOW and cook for approximately 6–8 hours.
During this time, the cabbage will gradually become tender while the sausage filling cooks thoroughly.
The marinara sauce will develop a deeper savory flavor as it combines with the natural juices released by the sausage and cabbage.
Avoid removing the lid during the cooking process because the slow cooker needs to maintain a consistent temperature.
Cooking time will vary depending on the size and thickness of the cabbage rolls, the temperature of the ingredients, and the performance of your slow cooker.
Begin checking for doneness toward the lower end of the cooking window.
The cabbage should be soft and easily pierced with a fork, while the sausage filling should be completely cooked.
Using an instant-read food thermometer, check the center of the largest cabbage roll. The sausage filling must reach an internal temperature of 165°F (74°C).
If the center has not reached the required temperature, continue cooking and check again.
Do not rely on the cooking time alone to determine whether ground pork sausage is fully cooked.
7. Rest the Cabbage Rolls
Once the cabbage rolls are fully cooked, turn off the slow cooker.
Carefully remove the lid, allowing the steam to escape away from your face.
The cabbage rolls will be very tender, so avoid lifting them with ordinary kitchen tongs.
Use a wide serving spoon or spatula to gently lift each roll from underneath.
Transfer them to a warm serving platter.
Allow the rolls to rest for approximately 5–10 minutes before cutting.
Resting helps the filling settle and makes the rolls easier to serve without falling apart.
Meanwhile, inspect the marinara sauce remaining in the slow cooker.
If the sauce is already thick and smooth, it can be served immediately.
If it looks too thin, carefully transfer it to a small saucepan and simmer over medium-low heat, stirring occasionally, until it reaches your preferred consistency.
8. Plate and Serve
For an attractive restaurant-style presentation, serve two cabbage rolls per plate.
Spoon a generous layer of warm marinara sauce onto the bottom of each serving plate.
Place one whole cabbage roll on one side of the plate.
Position the second roll beside it and carefully cut it crosswise into two equal halves using a sharp knife.
Arrange the cut halves so the exposed filling faces forward.
The cross-section should reveal the layers of tender cabbage, seasoned Italian sausage, cooked rice, and melted mozzarella in the center.
Spoon additional marinara sauce over the whole cabbage roll and around the base of the cut portions.
Leave the front cut surfaces visible so the melted mozzarella and sausage filling can be seen.
Serve immediately while the cabbage rolls are warm and the mozzarella center is soft and melted.
Tips for Perfect Italian Sausage Cabbage Rolls
Choose large cabbage leaves. Large outer leaves are easier to fill and fold. Smaller leaves may not completely cover the filling.
Soften the cabbage properly. The leaves should be flexible enough to roll without cracking. If they remain too firm, return them to the boiling water briefly.
Remove the thick cabbage ribs. Shaving down the central ribs makes rolling easier and helps the cabbage cook more evenly.
Use cooled rice. Completely cooled cooked rice is easier to incorporate into the sausage mixture and helps prevent the filling from becoming overly soft.
Keep the mozzarella enclosed. Always surround the cheese completely with the sausage mixture before wrapping it in cabbage. This helps prevent the cheese from escaping during cooking.
Avoid overfilling. Divide the mixture evenly between the eight leaves. Too much filling makes the rolls difficult to close and increases the risk of tearing.
Place the rolls seam-side down. This helps keep the cabbage leaves securely wrapped while they cook.
Arrange them snugly. Keeping the rolls close together helps them maintain their shape.
Do not add unnecessary liquid. The marinara sauce and moisture released during cooking provide sufficient liquid for this recipe.
Check the internal temperature. The center of the sausage filling must reach 165°F (74°C) before serving.

Storage and Reheating
Refrigerator: Allow leftover cabbage rolls to cool slightly, then transfer them into an airtight container with some of the marinara sauce. Refrigerate within two hours of cooking and consume within 3–4 days.
Freezer: Place completely cooled cabbage rolls in a freezer-safe container. Cover with marinara sauce to help protect them from drying out. Freeze for up to 2–3 months for best quality.
Reheating in the Microwave: Place one or two cabbage rolls in a microwave-safe dish. Add a spoonful of marinara sauce, cover loosely, and heat until steaming hot throughout, checking the center.
Reheating in the Oven: Arrange the rolls in an oven-safe baking dish and spoon additional marinara sauce over them. Cover with foil and heat at 325°F (163°C) until thoroughly heated.
Reheating in the Slow Cooker: Place the refrigerated rolls in the slow cooker with some marinara sauce. Cover and heat until they reach 165°F (74°C). Avoid using the WARM setting to reheat cold leftovers.
Frequently Asked Questions
Can I prepare these cabbage rolls ahead of time?
Yes. You can soften the cabbage leaves, prepare the sausage and rice filling, assemble all eight rolls, and refrigerate them in a covered container. For food safety, refrigerate promptly and use within 1–2 days. Add the marinara sauce when ready to cook. Because the rolls will start cold, cooking time may need to be adjusted.
Can I use ground pork instead of Italian sausage?
Yes. Ground pork can be used, but it will need additional seasoning. Consider adding garlic powder, onion powder, Italian seasoning, black pepper, and salt to recreate the flavor of Italian sausage.
Can I use fresh mozzarella?
Low-moisture mozzarella is recommended because it releases less moisture during cooking and provides a more controlled melted center. Fresh mozzarella contains more water and may produce a wetter filling.
Can I use brown rice?
Yes. Fully cooked and cooled brown rice can replace the white rice. The texture will be slightly firmer and the flavor a little nuttier.
Can I cook these cabbage rolls on HIGH?
LOW is recommended for the best texture and gradual cooking. If you need a shorter cooking time, HIGH may be possible, but the timing depends on your slow cooker and roll size. Always verify that the sausage filling reaches 165°F (74°C).
Why is my cabbage still firm?
The cabbage leaves may not have been softened sufficiently before assembly, or the rolls may need additional cooking time. Continue cooking until the leaves are fork-tender and the sausage filling is fully cooked.
Why did the mozzarella disappear?
The cheese may have escaped through an opening in the filling or cabbage leaf. Make sure the mozzarella is completely surrounded by sausage mixture and that every roll is securely wrapped.
Final Serving Suggestion
For the best presentation, serve two large rolls per plate with rich marinara sauce underneath, one whole roll, and one cut in half to reveal the melted mozzarella center.
Finish with a little freshly grated Parmesan and chopped fresh parsley if desired.
This Slow Cooker Italian Sausage & Mozzarella Cabbage Rolls recipe brings together tender cabbage, savory Italian sausage, fluffy rice, melted cheese, and rich tomato sauce in one comforting meal. It’s a delicious homemade dinner that makes simple ingredients feel special.
