Is a slightly brown bottom layer of rice normal or a sign of a problem?

A thin, pale golden crust on the very bottom of the pot (not dark brown or black) is normal and in many Asian cuisines is called nurungji (Korean) or socarrat (Spanish) and is considered desirable — it has a slightly toasted, nutty flavor. This light crust occurs when the bottom layer is heated slightly above the cooking temperature after the water absorbs — the rice toasts without burning. A dark brown or black scorched layer is not normal — it indicates too little water, too high heat, overloading, or a worn pot surface. The distinction: pale golden crust that releases easily from the pot is normal and good. Dark, stuck, acrid-smelling residue is a problem.

My rice cooker is new and already burning the bottom — is it defective?

Probably not defective — most new rice cooker scorching is a water ratio issue. New rice cooker models may require slightly more water than the previous model you used, or the rice brand you use absorbs water at a different rate than the calibration standard. Increase water by 2 tablespoons per cup of rice and test. Also check whether the rice was rinsed — unrinsed rice scorches more readily. If burning persists after increasing water by 3 to 4 tablespoons total: contact the manufacturer's customer service — an element that runs consistently too hot is a defect covered under warranty.

Can I use parchment paper in a rice cooker to prevent sticking?

This is not recommended. Parchment paper placed in the rice cooker pot creates an air barrier between the pot and the paper, which causes inconsistent heat distribution and unpredictable cooking. Additionally: parchment paper is not designed for immersion in boiling water during the cook cycle — the paper can absorb water, tear, and affect rice texture. The correct solutions for sticking are: correct water ratio, rinsed rice, and a pot with intact non-stick coating. Replacing a worn inner pot ($20 to $50) is the correct fix for a non-stick-depleted cooker.

Rice Cooker Burning the Bottom: 8 Causes and Fixes

A scorched bottom layer looks like a broken appliance, but it's rarely the cooker's fault.

Most of the time it's water, timing, or a worn pot doing exactly what you'd expect under the wrong conditions.

Not every dark layer is bad news, either. A thin golden crust, called nurungji in Korean cooking, is intentional and actually desirable.

This guide covers eight specific causes, from insufficient water to mineral buildup on the heating plate, with a direct fix for each one so you can isolate what's actually happening in your pot.

Quick Diagnosis

Symptom	Most Likely Cause	Fix
Thin golden crust, pale	Normal toasting	No action needed — this is correct
Dark brown/black scorch	Too little water	Increase water by 2 tbsp per cup
Sticking across entire bottom	Worn non-stick coating	Replace inner pot
Uneven burning (spots)	Scale on heating element	Clean heating plate with vinegar
Rice sticking, gummy	No rinsing; too much starch	Rinse rice before cooking
Overflow + burning	Overfilled	Stay below maximum capacity line
Burns only with new rice brand	Water absorption difference	Adjust water ratio by brand
