Ingredients
- 1 head large green cabbage, about 3 pounds
- 1 tbsp olive oil
- 1 medium yellow onion, finely diced
- 8 oz cremini or white mushrooms, finely chopped
- 3 clove garlic, minced
- 2 cup cooked brown or green lentils, well drained
- 1½ cup cooked white or brown rice
- ⅓ cup plain vegan breadcrumbs
- 2 tbsp chopped fresh parsley, divided
- 1 tbsp soy sauce
- 1 tsp smoked paprika
- 1 tsp fine salt, divided
- ½ tsp ground black pepper, divided
- 28 oz canned crushed tomatoes
- 15 oz canned plain tomato sauce
- ½ cup water
- 2 tbsp apple cider vinegar
- 1 tbsp packed light brown sugar, organic or labeled vegan
- 1 tsp dried oregano
Method
- 1
Bring an 8-quart pot half-filled with water to a boil, leaving enough room for the cabbage without overflowing.
- 2
Remove any damaged outer cabbage leaves and carefully cut a deep cone around the core with a small knife to remove it.
- 3
Lower the cabbage into the boiling water, core-side down. Turn it occasionally with tongs and gently loosen the outer leaves as they soften, transferring each flexible leaf to a rimmed baking sheet. Collect 12 large leaves, allowing about 12–18 minutes total; lift out the remaining cabbage.
- 4
Heat the olive oil in a 12-inch skillet over medium-high heat. Add the onion and mushrooms and cook for 8–10 minutes, stirring occasionally, until the onion is soft, the mushrooms have browned in spots, and no liquid pools in the pan.
- 5
Stir the garlic into the skillet and cook for 30 seconds, then remove the skillet from the heat.
- 6
Mash about 1/2 cup of the lentils in a large bowl with a fork. Fold in the remaining lentils, rice, mushroom mixture, breadcrumbs, 1 tablespoon parsley, soy sauce, smoked paprika, 1/2 teaspoon salt, and 1/4 teaspoon pepper. Let cool for 5 minutes.
- 7
Whisk the crushed tomatoes, tomato sauce, water, vinegar, brown sugar, oregano, remaining 1/2 teaspoon salt, and remaining 1/4 teaspoon pepper together in a separate bowl.
- 8
Shave the thick raised rib on the underside of each cooled cabbage leaf with a small knife, keeping the leaf intact so it bends easily.
- 9
Divide the filling evenly among the 12 leaves, using about 1/3–1/2 cup per leaf. Place the filling near the stem end, fold the bottom over it, fold in both sides, and roll into a snug parcel.
- 10
Spread 1 cup of the tomato sauce across the bottom of a 6-quart slow cooker.
- 11
Arrange 6 rolls seam-side down over the sauce, spoon half the remaining sauce over them, then add the remaining rolls and cover with the rest of the sauce.
- 12
Cover and cook on LOW for 6–7 hours or HIGH for 3–4 hours, until a fork slides easily through the thickest part of a cabbage leaf and the centers are steaming hot. Keep the lid closed until the earliest checking time.
- 13
Let the rolls rest with the heat off for 10 minutes before lifting them out with a wide spoon. Serve 2 rolls per person with sauce and the remaining 1 tablespoon parsley.
The story behind it
These cabbage rolls tuck lentils, rice, and browned mushrooms inside tender cabbage leaves, then simmer slowly in a tangy tomato sauce. The filling uses familiar grocery-store ingredients and holds together without eggs. Serve them with mashed potatoes or crusty bread to catch the extra sauce.
Comfort Food That Works in the Slow Cooker
Cabbage leaves need time and moisture to become tender without falling apart. A covered slow cooker provides both, while the tomato sauce keeps the rolls moist around the edges. Cooked lentils and rice make the filling predictable: there is no guessing whether dry grains will absorb enough liquid inside a tightly wrapped leaf.
Mushrooms add texture, but they need to lose their excess moisture before joining the filling. Cook them until the skillet looks mostly dry and some pieces have browned. Letting the filling cool briefly also makes the rolls easier to handle.
Helpful Tips and Substitutions
- Choose a large cabbage: A head weighing about 3 pounds usually provides enough broad leaves for 12 rolls. If a leaf tears, overlap the torn edges or patch it with a piece of another softened leaf.
- Use firm lentils: Brown or green lentils hold their shape. Red lentils break down too much for this filling. Drain canned lentils thoroughly before measuring.
- Start with cooked rice: White or brown rice works. If cooking from scratch, about 1/2 cup dry rice makes the amount needed here. Cook it separately according to the package directions.
- Keep the filling flexible: Plain breadcrumbs help bind the mixture. Choose breadcrumbs without dairy or eggs, or use certified gluten-free breadcrumbs and tamari for a gluten-free version.
- Save the remaining cabbage: Shred unused leaves for soup, stir-fries, or a skillet side dish. Refrigerate them in a covered container.
Make-Ahead and Storage
You can prepare the filling and soften the cabbage leaves a day ahead. Refrigerate them separately in covered containers, then assemble before cooking. Do not refrigerate the filled slow cooker insert unless the manufacturer specifically allows moving a cold insert directly into the heating base.
Refrigerate cooked rolls with their sauce in shallow, covered containers within 2 hours. Keep for up to 4 days, or freeze for up to 3 months. Thaw frozen rolls overnight in the refrigerator. Reheat covered in a 350°F oven with a splash of water until the centers reach 165°F, usually 25–35 minutes for refrigerated rolls. Individual portions can also be microwaved, covered, until hot throughout.
Frequently Asked Questions
Can I put raw rice in the filling?
Not in this version. Raw rice changes the liquid requirements and expands inside the rolls. Use cooked rice for a filling that stays moist and cooks evenly.
Can I use savoy cabbage?
Yes. Its flexible, crinkled leaves are good for rolling and often soften faster than green cabbage. Remove each leaf from the boiling water as soon as it bends easily.
Why are my cabbage rolls still firm?
The leaves may have been thick or insufficiently softened before rolling. Keep the lid closed and continue cooking in 30-minute increments until a fork passes easily through the cabbage.
Can I leave out the mushrooms?
Replace them with 1 additional cup of cooked, well-drained lentils. Mash about half of those extra lentils so the filling stays cohesive rather than loose.
Spoon plenty of tomato sauce over each serving. The rolls also reheat well, so tuck away a few for tomorrow’s lunch.
