Indian Potatoes with Kohlrabi and Spices Recipe
A dry North Indian-style sabzi in which soft potatoes and faintly crisp kohlrabi are coated with cumin, mustard, turmeric, coriander and chili. Lemon juice lifts the earthy vegetables at the end, while fresh coriander adds a cool, herbal finish. The listed two kohlrabi are intended to be medium bulbs, about 7–9 cm across; peel away any tough, fibrous layer before cubing.
Kohlrabi is especially familiar in Kashmiri food, while dry potato-and-vegetable sabzis flavored with whole seeds and ground spices are found throughout northern Indian home cooking. This preparation follows that everyday sabzi method without claiming to reproduce one specific regional classic.
Kohlrabi does more than bulk out the potatoes: its mild cabbage-like sweetness and firmer texture keep the sabzi from feeling uniformly soft. Toasted whole seeds provide small bursts of nuttiness, and the final uncovered frying concentrates the onion and spices into a savory coating rather than a sauce.
Why this version works
- Cutting both vegetables into 1.5 cm cubes helps the potato soften before the kohlrabi loses all of its bite.
- Blooming the whole seeds first and adding the ground spices only after the onion and ginger protects the finer spices from burning.
- A small amount of water creates enough steam to cook the centers without turning the dish into a curry.
- Testing the potatoes with a knife is more reliable than relying on a single cooking time, since waxy and floury varieties soften at different rates.
- The uncovered finish evaporates residual moisture and restores the concentrated, dry texture expected of a sabzi.
Chef's tips
Use a wide pan rather than a small saucepan so the vegetables sit in a relatively shallow layer. This encourages light browning before the braise and lets the 50 ml water evaporate quickly at the end. Keep the lid closed between stirs; escaping steam can leave the potatoes undercooked before the pan dries out.
How to serve
Serve the sabzi hot with roti, chapati or plain rice, either as a vegetable side or as part of a larger meal. It also works at room temperature, when the lemon and toasted seed flavors become more pronounced.
Watch out for
- Kohlrabi bulbs vary considerably. This recipe assumes two medium bulbs about 7–9 cm across; very large bulbs may have a woody base that needs deeper peeling.
- Do not wait for every mustard seed to pop. By then, the cumin may be burnt and bitter.
- If the ground spices catch on the pan or smell acrid, add the vegetables immediately and stir; they will cool the surface.
- Avoid judging doneness by the kohlrabi alone. The potato should have no chalky center, even if that means extending the covered cooking time by several minutes.
- Stir with a folding motion during the final reduction so the softened potato cubes do not break apart.
Substitutions
- Rutabaga can replace the kohlrabi, but it is denser and generally takes longer, not less time, to soften. Cut it into the same 1.5 cm cubes and fry it for about 5 minutes before adding the potatoes, then continue with the covered braise.
- Either waxy or floury potatoes can be used in the stated quantity. Waxy potatoes hold their shape particularly well but may need an additional 3–6 minutes of covered cooking.
Ingredients
- potatoes - 500 g
- kohlrabi - 2 pieces
- onion - 1 piece
- oil - 3 tablespoons
- cumin seeds - 0.5 teaspoons
- mustard seeds - 0.5 teaspoons
- turmeric - 0.5 teaspoons
- ground coriander - 1 teaspoon
- chili powder - 0.25 teaspoons
- ginger fresh - 10 g
- water - 50 ml
- lemon juice - 1 tablespoon
- fresh coriander leaves - 2 tablespoons
- salt
Preparation
- Peel the 500 g potatoes. Trim and peel both kohlrabi, cutting deeply enough to remove the fibrous layer beneath the skin, especially near the base. Cut both vegetables into even 1.5 cm cubes.
- Slice the peeled onion into thin half-moons and finely grate or chop the 10 g ginger. Have the ground spices measured before heating the oil, as they cook quickly.
- Heat the 3 tablespoons oil in a wide frying pan with a lid over medium heat. Add the cumin and mustard seeds. Cook for 30–40 seconds, until the mustard seeds begin popping and the cumin smells toasted; lower the heat immediately if the seeds blacken.
- Add the onion and cook for 5–7 minutes, stirring regularly. It should become soft and translucent with pale golden edges rather than deeply browned.
- Stir in the ginger and cook for 1 minute. Add the turmeric, ground coriander and chili powder, then stir for 20–30 seconds. The spices should become fragrant and slightly darker but must not scorch.
- Add the potatoes and kohlrabi with 1/2 teaspoon salt. Turn the pieces repeatedly until evenly stained yellow and coated with the onion-spice mixture. Fry for 3–4 minutes, allowing a few edges to take on light color.
- Pour in the 50 ml water, scrape any spices from the bottom and cover the pan. Reduce the heat to low and cook for 12 minutes, stirring about every 4 minutes. Test a potato cube with the tip of a knife: it should slide in without a hard center, while the kohlrabi should be tender with a slight bite. Floury potatoes may be ready at this point; waxy varieties can require another 3–6 minutes covered.
- Remove the lid once the potatoes are cooked. Raise the heat to medium and cook for 2–3 minutes, folding gently so the cubes stay intact, until no water pools in the pan and the spices cling to the vegetables. Taste for salt, turn off the heat, add the lemon juice and fresh coriander, and toss once more.
Storage
Store the dish in an airtight container in the fridge and reheat in a frying pan with 1–2 tablespoons of water until the vegetables are hot again., You can freeze it for up to 2 months, but the kohlrabi will be a bit softer after defrosting.
The appealing part of this dish is the contrast at the fork: the potato yields completely, while the kohlrabi retains just enough resistance to remain distinct. I would not cook the kohlrabi until it becomes as soft as the potato, because that small textural difference gives this simple sabzi much of its character.
