Tangy Mustard Cabbage Slaw with Caraway
A bright, assertive slaw with crisp green cabbage and thin-sliced onions bound in a punchy mustard-vinegar dressing spiked with caraway seeds. This is not a creamy slaw—the sharp vinegar and mustard cut through rich foods, making it ideal alongside fatty meats, sausages, or sandwiches. The slaw softens slightly as it sits, allowing the flavors to meld, and keeps for days in the fridge.

Steps
Before you start
- Read the recipe through—this is a raw slaw that gets better as it sits, so plan ahead if serving later.
- Have a sharp knife or mandoline ready for slicing cabbage and onions paper-thin.
- Chill a serving bowl in the fridge if you want the slaw to stay as crisp as possible.
Slice cabbage and onion
- Halve the green cabbage lengthwise and cut out the core.
- Slice the cabbage halves as thinly as possible—ideally about 1/8 inch (3 mm)—using a sharp knife or mandoline; you should have about 5 cups of shreds.
- Halve the yellow onion lengthwise and slice it similarly into thin half-moons.
- Place both in a large mixing bowl.

Ready when: Cabbage and onion are sliced uniformly thin
Tip: A mandoline speeds this up and ensures even slices, which helps the slaw absorb dressing uniformly. Be careful of your fingertips.
Salt the vegetables
- Sprinkle the cabbage and onion with 0.75 teaspoon (4.5 g) of kosher salt.
- Toss well to coat evenly.
- The salt will draw moisture from the vegetables, beginning to soften them slightly and making room for the dressing to cling.

Ready when: Salt is evenly distributed throughout
Tip: Salting ahead of the dressing helps the slaw soften slightly without becoming soggy, and it brings out the vegetables' natural flavors.
Toast caraway seeds
- In a small dry skillet over medium heat, toast 1.5 teaspoons (4 g) of caraway seeds, stirring occasionally, until they become fragrant and begin to brown slightly, about 2 minutes.
- Transfer to a small bowl and let cool for 1 minute.
- This step awakens their warm, slightly citrusy flavor.

Ready when: Seeds are fragrant and lightly golden-brown
Tip: Don't skip toasting—raw caraway tastes muted and dusty by comparison. If you prefer a gentler caraway flavor, use 1 teaspoon (2.5 g) instead.
Make the dressing
- In the small bowl with the toasted caraway seeds, add 3 tablespoons (45 ml) of yellow mustard, 3 tablespoons (45 ml) of red wine or apple cider vinegar, and 2 tablespoons (30 ml) of neutral oil.
- Whisk together until smooth and combined.
- The dressing should be thick yet pourable, with flecks of caraway throughout.

Ready when: Dressing is well mixed and uniform in color
Tip: If using whole-grain mustard, you'll see more texture; smooth mustard will be silkier. Both work well here.
Dress the slaw
- Pour the mustard-caraway dressing over the salted cabbage and onion.
- Using your hands or two spoons, toss thoroughly for about 1 minute, making sure every strand is coated in dressing.
- The slaw will look wet and slightly clumpy at first.

Ready when: Every piece of cabbage and onion is coated with dressing
Tip: Don't be afraid to toss aggressively—you want good contact between dressing and vegetables.
Season and rest
- Taste the slaw and season with freshly ground black pepper and additional salt if needed.
- Transfer to a chilled serving bowl (or leave in the mixing bowl) and let rest at room temperature for at least 15 minutes, or cover and refrigerate for up to 2 hours before serving.
- As it rests, the cabbage will soften slightly and the flavors will deepen and meld.

Ready when: Slaw is flavorful and cabbage has lost its raw crunch
Tip: If serving later, keep it chilled—the slaw stays crisp longer when cold and holds for 3–4 days in the fridge.
Good to know
Tips
- This slaw is assertively flavored and designed to cut through rich foods—serve it alongside bratwurst, pulled pork, smoked brisket, or fatty sausages. It also works well on sandwiches and burgers.
- For a creamier slaw, whisk 2–3 tablespoons (30–45 ml) of mayonnaise or sour cream into the dressing.
- If you want the slaw to stay crispier longer, drain off excess liquid before serving—the cabbage will have released moisture as it rests.
- Make a larger batch and store it in the fridge; it keeps for several days and is great to have on hand for weeknight meals.
Make ahead
This slaw actually improves with time. Make it up to 4 hours ahead and refrigerate it; the flavors deepen and the cabbage becomes more tender. It's best served cold or at cool room temperature.
Storage & reheating
Store in an airtight container in the refrigerator for up to 4 days. The slaw will soften and become more tender over time, and any excess liquid can be drained off before serving. It does not freeze well.
Substitutions
- yellow mustard, whole-grain or smooth → Dijon mustard or whole-grain mustard. Dijon will be sharper and more refined; whole-grain will add texture and a slightly nuttier flavor. Use the same amount.
- red wine vinegar or apple cider vinegar → White wine vinegar or distilled white vinegar. White wine vinegar is milder and slightly more delicate; distilled white is more aggressive. Apple cider vinegar adds a subtle sweetness. Adjust quantity to taste.
- caraway seeds → Fennel seeds or dill seeds. Fennel is slightly sweeter and more licorice-forward; dill adds an herbaceous note. Toast and use the same amount, or adjust to taste.
- green cabbage, cored → Napa cabbage or red cabbage. Napa is milder and more delicate; red cabbage is earthier and will stain the dressing. Both benefit from thin slicing.
