Steaming vegetables, dumplings, fish, and more in a Zojirushi rice cooker is one of the easiest ways to get perfectly cooked side dishes without using another pot. The machine’s sealed, steam-filled environment cooks food gently and evenly, and the included steaming basket fits right over the rice as it cooks or on its own. This guide walks you through the exact settings, water amounts, and times so you can use your Zojirushi as a reliable steamer every time.
Ingredients
- 1 cup (185 g) sushi or short-grain rice, rinsed (optional, for cooking rice underneath)
- 1 1/4 cups (300 ml) water for rice (if cooking rice)
- 2 cups (300 g) broccoli florets, carrots sliced 1/4-inch thick, or green beans trimmed
- 1/2 lb (225 g) fish fillets (like salmon or cod), patted dry
- 1 tbsp (15 ml) soy sauce or tamari
- 1 tsp (5 ml) sesame oil
- 1/4 tsp salt
- 1/4 tsp black pepper
- 1/2 cup (120 ml) water for steaming (plus more if steaming without rice)
Instructions
- If cooking rice and steaming at the same time, rinse the rice under cold water until the water runs clear, then add it to the inner cooking pan with 1 1/4 cups (300 ml) water. If steaming only, add 1/2 cup (120 ml) water to the empty inner pan.
- Place the steaming basket inside the inner pan, making sure it sits flat and does not touch the water below (the water should be below the basket’s holes).
- Arrange the vegetables or fish in a single layer in the steaming basket. For fish, season with salt, pepper, soy sauce, and sesame oil. For vegetables, toss with a pinch of salt.
- Close the lid securely. Press the Steam cycle if your model has it (like the Neuro Fuzzy or Induction Heating models). If your model does not have a Steam cycle, press the White Rice or Quick Cooking cycle instead.
- Set the timer for 10–15 minutes for vegetables (broccoli, green beans, carrots) or 12–15 minutes for fish fillets. The timer starts once the cooker reaches steaming temperature, which takes about 5 minutes.
- When the timer beeps, carefully open the lid away from your face to avoid steam burns. Check that vegetables are fork-tender and fish flakes easily with a fork. Fish should reach a safe minimum internal temperature of 145°F (63°C) per USDA FSIS guidelines, checked with a food thermometer.
- Remove the steaming basket using tongs or oven mitts. If you cooked rice underneath, fluff it with the rice paddle and serve immediately.
Tips
- Don’t overcrowd the basket: Leave space between pieces so steam circulates. Overlapping food steams unevenly and takes longer.
- Cut vegetables uniformly: Slice carrots, potatoes, or squash into similar-sized pieces (about 1/4-inch thick) so they finish at the same time.
- Use the right water level: For steaming only, 1/2 cup (120 ml) water is usually enough for 15 minutes. For longer steaming, add 1 cup (240 ml) water. Never fill above the inner pan’s marked water line for rice.
- Season after steaming: For vegetables, a light drizzle of olive oil and a squeeze of lemon after steaming brightens flavor without making them soggy.
Serving Suggestions
Serve steamed vegetables alongside grilled chicken or teriyaki salmon with a bowl of steamed rice. Steamed fish goes well with a side of soy-ginger dipping sauce and a simple cucumber salad. For a light meal, pile steamed broccoli and carrots over rice and drizzle with sesame dressing. Steamed dumplings or bao buns can be served with black vinegar and chili oil for a dim sum-style spread.
Variations
- Steamed dumplings: Place frozen or fresh dumplings in the basket, leaving space between them. Steam for 12–15 minutes until the wrappers are translucent and the filling is hot (165°F / 74°C for poultry or pork dumplings).
- Steamed eggs (chawanmushi): Pour a mixture of beaten eggs, dashi, and soy sauce into small ramekins, place them in the basket, and steam on a low setting for 15–20 minutes until just set.
- Steamed sweet potatoes: Cut into 1-inch cubes and steam for 20–25 minutes until easily pierced with a fork.
- Steamed chicken breast: Season thin chicken cutlets and steam for 15–18 minutes until the internal temperature reaches 165°F (74°C) per USDA FSIS guidelines.
Storage and Reheating
Refrigerate leftover steamed vegetables and fish within 2 hours of cooking in airtight containers. Steamed vegetables keep for 3–4 days; steamed fish keeps for 2–3 days. To reheat, place leftovers in the steaming basket with 1/4 cup (60 ml) water in the pan and steam for 3–5 minutes, or microwave in 30-second bursts until hot. Do not reheat fish more than once. Steamed rice can be refrigerated for up to 4 days and reheated in the microwave with a damp paper towel over it for 1–2 minutes.
Frequently Asked Questions
Can I steam without the steaming basket? No, the basket keeps food above the water. Without it, food will boil in the water instead of steaming. If you lost the basket, use a heatproof silicone steamer insert that fits your model, or place a small heatproof colander inside the pan.
Why is my food still raw after the timer goes off? The timer on some Zojirushi models starts counting after the water reaches boiling, but on others it starts immediately. If your food is undercooked, add 5 more minutes and check again. Also make sure the lid is fully closed and the vent is not blocked.
Can I steam rice and vegetables at the same time? Yes, this is a popular feature. Add rice and water to the pan, place the basket with vegetables on top, and start the Steam cycle. The vegetables will cook in the steam rising from the rice water. Check them after 10 minutes so they don’t overcook.
How much water should I put in for steaming only? Use 1/2 cup (120 ml) for up to 15 minutes of steaming, and 1 cup (240 ml) for up to 25 minutes. If the pan runs dry, the cooker will switch to keep-warm mode automatically on most models, but check water levels before starting.
Is it safe to steam frozen vegetables? Yes, frozen vegetables steam well. Add 3–5 minutes to the cooking time and spread them out so they thaw evenly. No need to defrost first.
Why does my fish stick to the basket? Lightly oil the basket or line it with a piece of parchment paper with holes punched in it. This prevents sticking and makes cleanup easier. Do not use foil, as it blocks steam circulation.
