Kohlrabi
6.7best for rawMild root, good raw or cooked
Raw turnip slices carry a sharp horseradish-adjacent bite from intact sinigrin, which only releases when myrosinase contacts cut surfaces — so pre-slicing 30 minutes ahead intensifies the heat. Mandoline to 1.5mm for slaws or julienne for crudite trays. Food-safety-wise, scrub well and refrigerate below 40°F since soil-borne organisms cling to the skin. This page judges substitutes by raw-bite intensity, room-temperature texture stability, and whether they brown when cut.
Mild root, good raw or cooked
Swap 1:1 by cup. Raw kohlrabi tastes like a cleaner, crunchier turnip with no bitter outer note once peeled past the fibrous 2mm skin. Julienne for slaws or shave on a mandoline at 1mm. Holds crunch in vinaigrette for 6 hours versus turnip's 3 because of denser cell walls and lower 88% water.
Neutral starch, works in any dish
Swap 1:1 by cup only with caution — raw potato contains solanine that's mildly toxic above 200mg per kg, plus raw starch is indigestible. Never serve raw potato in slaws. If absolutely needed for a starch-water-extraction recipe, use russet, grate, and rinse twice. Refrigerate below 40°F throughout to inhibit any sprouting compounds.
Sweeter, good mashed or roasted
Swap 1:1 by cup. Raw parsnip grated fine reads sweet and herbal, with none of turnip's mustard heat. Cut at 1mm on a mandoline for slaw — thicker slices read woody since parsnip fibers are more pronounced. Refrigerate cut surfaces under acidulated water (1 tablespoon lemon per quart) to prevent surface oxidation browning.
Sweeter and softer, adjust cook time down
Swap 1:1 by cup. Raw sweet potato shreds eat sweet and grassy, with a starch-chalky finish — soak shreds 15 minutes in ice water then drain to crisp. Salt 10 minutes before serving to draw water and concentrate flavor. Refrigerate at or below 40°F since cut surfaces oxidize within 30 minutes at room temperature.
Peppery, great roasted as turnip sub
Swap 1:1 by cup. Raw radish keeps a sharper bite than turnip from intact sinigrin — pleasing in a slaw with creamy dressing that softens the heat. Slice 1.5mm thick; thinner discs go limp in 20 minutes. Hold in ice water for crispness up to 2 hours before draining and tossing with vinaigrette.
Sweeter, similar dice size for stews
Swap 1:1 by cup. Raw carrot grates are familiar and sweet — 6% sugars, no mustard heat. Use the large holes of a box grater for slaw, fine for finishing salads. Refrigerate below 40°F; cut carrot dries out fast and curls within 90 minutes at room temperature, losing its snap on the plate.
Mild flavor, mash as turnip substitute
Swap 1:1 by cup. Raw cauliflower riced or finely shaved eats neutral and slightly grassy, with no bitter edge. Wash thoroughly — its tight floret structure traps soil and field bacteria. Refrigerate below 40°F and consume within 2 days of cutting, since cut surfaces brown and develop sulfur notes by day 3.
Cube and roast, mild and slightly sweet
Mild root, mash with butter for similar body
Similar density, less sweet
Mild when cooked, slice thin for raw salads
