Full Ingredients

For the Caramelized Cabbage

800 g (1 lb 12 oz) green cabbage, weighed after removing the core and damaged outer leaves
250 g (8.8 oz) yellow onions, peeled and finely diced
45 g (3 tablespoons) unsalted butter
15 ml (1 tablespoon) neutral oil, such as sunflower or canola oil
8 g (2 teaspoons) granulated sugar
6 g (1 teaspoon) fine sea salt, divided into two ½-teaspoon portions
2 g (1 teaspoon) freshly ground black pepper, divided into ¾ teaspoon and ¼ teaspoon
15 ml (1 tablespoon) apple cider vinegar

For the Pasta

300 g (10.6 oz) dried fleckerl, ideally squares approximately 2 cm (¾ inch) across
3 liters water
12 g (2 teaspoons) fine sea salt, for the cooking water
120 ml (½ cup) reserved pasta cooking water; use 60 ml (¼ cup) initially and the remainder only as needed

Pasta substitute: If you cannot find fleckerl, break wide, dried egg noodles into roughly 2 cm (¾-inch) pieces. Small, flat pieces are the goal: they should mingle with the cabbage rather than overwhelm it.

Step-by-Step Instructions

Step 1: Prepare the cabbage and onions

Remove the cabbage’s damaged outer leaves, quarter it, and cut out the tough core. Weigh out 800 g of trimmed cabbage, then cut it into approximately 1.5 cm (⅝-inch) squares. Separate any tightly packed pieces with your fingers. Peel and finely dice the onions.

Have a large, heavy, deep skillet or wide Dutch oven ready, ideally about 30 cm (12 inches) across. A broad cooking surface helps moisture evaporate so the cabbage can brown.

Step 2: Soften the onions

Add the butter and oil to the skillet and heat over medium heat for 1 minute, until the butter has melted and begins to foam. Add the onions and cook for 8 minutes, stirring frequently, until softened and pale golden. If they begin developing dark edges, lower the heat slightly.

Step 3: Add a little caramel sweetness

Sprinkle the sugar evenly over the onions. Cook over medium heat for 1 minute, stirring continuously, until the sugar dissolves and the onions look glossy. You are looking for a light caramel color, not dark or smoking sugar.

Step 4: Slowly brown the cabbage

Add the cabbage and ½ teaspoon of the salt. Toss thoroughly to coat it in the buttery onions; the pan will look full at first. Cover and cook over medium heat for 5 minutes, stirring once halfway through, until the cabbage begins to wilt.

Uncover, reduce the heat to medium-low, and cook for 30 minutes. Stir and scrape the bottom every 3 minutes, giving the cabbage time to make contact with the pan between stirs. It should become very tender, with golden-brown edges and darker caramelized patches.

Use the color as your guide: If the cabbage is still wet and pale near the end, raise the heat to medium for the final 5 minutes. If it starts scorching, lower the heat immediately. Depending on the cabbage’s moisture and your pan, reaching a deep golden color may take a few extra minutes.

Step 5: Cook the pasta while the cabbage browns

During the uncovered cabbage-cooking stage, bring 3 liters water to a rolling boil in a large pot. Add the 12 g salt. Time the pasta so it finishes close to the end of the cabbage’s cooking time.

Add the pasta and cook for 8 minutes, or follow the package’s stated al dente time if different. Stir occasionally to keep the squares from sticking together. Before draining, scoop out 120 ml (½ cup) cooking water. Drain the pasta without rinsing.

Step 6: Bring everything together

Once the cabbage is tender and browned, add the vinegar and stir over medium heat for 1 minute, scraping up the flavorful browned bits from the bottom of the pan.

Add the drained pasta, 60 ml (¼ cup) reserved cooking water, the remaining ½ teaspoon salt, and ¾ teaspoon black pepper. Toss gently over medium heat for 3 minutes, until the pasta and cabbage are evenly mixed and lightly glossy. There should be no pool of liquid in the pan.

Step 7: Finish and serve

Use the final 1 minute to check the texture and portion the dish. If it seems dry, add the remaining pasta water in 15 ml (1 tablespoon) additions, tossing after each addition; you may not need it all.

Divide among four warmed shallow bowls and sprinkle with the remaining ¼ teaspoon black pepper. Serve immediately. A crisp cucumber salad or lightly dressed green salad makes a refreshing accompaniment.

Pro Tips

Choose green cabbage: Ordinary white or green cabbage gives the familiar sweet flavor and sturdy texture. Red cabbage changes both the color and character of the dish.
Do not rush the browning: Tender cabbage is only halfway there. The golden patches are what give Krautfleckerl its rich, savory sweetness.
Keep the pieces small: Cabbage pieces slightly smaller than the pasta squares help every forkful contain both.
Grind the pepper fresh: Its warm, fragrant bite is a defining flavor, not just a final decoration.
Aim for a light coating: This is not a saucy pasta. The finished squares should glisten with butter and cooking juices without sitting in liquid.

Variations

Vegan Krautfleckerl: Use egg-free pasta and replace the 45 g butter with 45 ml (3 tablespoons) additional neutral oil. Keep the original tablespoon of oil, for 60 ml oil total.
With caraway: Add 1 g (½ teaspoon) lightly crushed caraway seeds during the final minute of cooking the onions for a warm, earthy accent.
Without added sugar: Omit the 2 teaspoons sugar and skip its 1-minute cooking stage. Let the cabbage brown for an additional 5 minutes if needed; the flavor will be a little less sweet.

Storage & Make-Ahead

Refrigerate: Cool leftovers promptly and refrigerate in an airtight container within 2 hours of cooking. Store for up to 4 days.

Reheat: For one serving, place the pasta in a skillet with 30 ml (2 tablespoons) water. Cover and heat over medium-low heat for 5 minutes, then uncover and toss for 2 minutes. Continue heating if necessary until the center reaches 74°C (165°F).

Make ahead: Cook the cabbage mixture through the vinegar addition up to 2 days ahead, then cool and refrigerate. Reheat it thoroughly in the skillet while you cook fresh pasta, then finish with the reserved pasta water, remaining salt, and pepper.

Freeze: Freeze cooled portions for up to 2 months. Thaw overnight in the refrigerator before reheating. The pasta will be softer after freezing, so freshly cooked pasta is best when making the cabbage ahead.
