How to Make Perfect Congee (Rice Porridge) in a Rice Cooker
Congee is the ultimate comfort food across Asia. Your rice cooker's porridge setting was literally designed for this dish.
What Is Congee?
Congee is rice cooked in a large volume of water or broth until the individual grains break down completely into a thick, creamy porridge. It goes by different names across Asia — jook in Cantonese, okayu in Japanese, cháo in Vietnamese, juk in Korean — and each culture has its own preferred consistency, toppings, and accompanying dishes.
What unites every version is the technique: a small amount of rice simmered slowly in a lot of liquid for a long time. The result is deeply comforting, easy to digest, and endlessly customizable. It’s the chicken soup of Asian cuisine — the food you eat when you’re sick, tired, celebrating, or just craving something warm and simple.
Your rice cooker’s porridge setting was engineered specifically for this dish. It uses a lower, gentler heat and a longer cook time than the standard rice mode, which allows the grains to gradually disintegrate without scorching on the bottom.
Choosing Your Rice
The type of rice you use matters significantly for congee. Short-grain and medium-grain white rice varieties produce the creamiest results because their high amylopectin starch content breaks down into a smooth, velvety texture.
Jasmine rice is another excellent choice and the traditional pick for many Southeast Asian congee recipes. It breaks down nicely and adds a subtle floral aroma.
Avoid long-grain varieties like basmati for congee. Their high amylose content keeps the grains too intact — you’ll end up with soupy rice rather than true porridge.
Some cooks use a mix: 80% short-grain white rice for creaminess and 20% glutinous (sweet) rice for extra body and silkiness. This blend produces exceptional congee if you can find both varieties.
The Golden Ratio
The ratio of rice to liquid is the single most important variable, and it determines whether your congee is a thick, spoonable porridge or a light, drinkable soup.
- Thick congee (Cantonese-style): 1 cup rice to 7 cups liquid
- Medium congee (all-purpose): 1 cup rice to 9 cups liquid
- Thin congee (soup-like, Vietnamese-style): 1 cup rice to 12 cups liquid
For a rice cooker, the 1:8 ratio is the ideal starting point. It produces a medium-bodied congee that’s thick enough to hold toppings but fluid enough to eat with a spoon. You can always thin it with hot water after cooking, but you can’t easily thicken it beyond simmering it down.
Basic Rice Cooker Congee Instructions
-
Rinse 1 cup of rice under cold water until the water runs mostly clear. This removes excess surface starch that can make the congee gluey rather than creamy. There’s a difference — check the rinsing and starch science guide if you’re curious about why.
-
Add the rice and 8 cups of water or chicken broth to the inner pot. Broth produces more flavorful congee, but water works perfectly well if you’re adding savory toppings and seasonings later.
-
Add aromatics. A 1-inch piece of fresh ginger (sliced into coins), a pinch of salt, and optionally a few dried scallops or a small handful of dried shrimp for umami depth. These aromatics infuse the congee as it cooks.
-
Select the Porridge setting. If your cooker has one, this is the button to use. It’s programmed for the longer, gentler cook that congee requires. If your cooker lacks a porridge setting, use the standard Cook function, but be prepared to restart the cycle — the cooker will switch to Keep Warm before the congee is fully broken down.
-
Cook for 1 to 1.5 hours. Stir once or twice during cooking if you can, which helps the grains break down evenly and prevents the bottom from sticking.
-
Check the consistency. The congee is done when the individual grains have completely dissolved into a smooth, creamy porridge with no visible intact grains. If it’s too thick, stir in hot water a quarter cup at a time. If it’s too thin, leave the lid off on Keep Warm for 15-20 minutes to let excess moisture evaporate.
Regional Variations
Cantonese-Style (Jook)
The Cantonese version is the most widely known outside Asia. It uses a thick consistency (1:7 ratio) and is typically made with chicken broth. Classic preparations include:
- Pork and century egg congee — the most iconic version. Marinated lean pork strips and sliced century egg are stirred in during the last 10 minutes of cooking.
- Fish congee — thin slices of fresh white fish are placed on top of the hot congee just before serving. The residual heat gently poaches the fish.
- Sampan congee — a everything-in-the-pot version with peanuts, dried squid, fish cakes, and lettuce.
Japanese-Style (Okayu)
Japanese okayu is much thinner and simpler than Cantonese congee. It uses a 1:10 or 1:12 ratio and is typically seasoned with just salt and served with pickled plum (umeboshi), a sprinkle of furikake, or a raw egg stirred into the hot porridge. It’s considered healing food in Japan, served to people who are sick or recovering.
Korean-Style (Juk)
Korean juk is medium-bodied and often enriched with ingredients like pumpkin, pine nuts, black sesame, red bean, or abalone. The rice is sometimes ground or partially blended before cooking to create an extra-smooth texture.
Classic Toppings
Half the joy of congee is customizing your bowl. Here are the most popular toppings across different traditions:
- Sliced scallions and a drizzle of toasted sesame oil
- A soft-boiled egg, halved, or a century egg, quartered
- Shredded poached chicken or ground pork
- Crispy fried shallots or garlic chips
- Soy sauce and white pepper (the classic Cantonese table condiments)
- Pickled vegetables, kimchi, or pickled mustard greens
- Crispy wonton strips or Chinese fried dough (youtiao)
Pro Tips for Better Congee
Freeze rice for faster breakdown. Freeze raw rice overnight before cooking congee. Freezing causes ice crystals to form inside the grains, which rupture the cell walls. The damaged grains break down much faster during cooking, cutting your congee time by 20-30 minutes.
Use a mix of broth and water. Full broth can be overpoweringly savory. A 50/50 split of broth and water gives flavor without heaviness.
For extra creaminess, soak the raw rice in water for 30 minutes to an hour before cooking. The pre-hydrated grains break down faster and more completely, producing a silkier result.
Congee thickens dramatically as it cools. This catches many first-timers off guard. What looked like a perfect consistency in the pot becomes thick paste once it cools in the bowl. Make your congee slightly thinner than your target consistency to account for this. Add hot water or broth when reheating — it’ll thin right back out.
Leftover congee stores well. Refrigerate in an airtight container for up to 3 days. It will solidify in the fridge, which is normal. Reheat with a splash of water on the stove or microwave, stirring frequently, until it returns to porridge consistency.

Frequently Asked Questions
What type of rice is best for congee?
Short-grain or medium-grain white rice produces the creamiest congee because of its high amylopectin starch content. Jasmine rice works well too and adds a subtle floral fragrance. Avoid long-grain varieties like basmati — they stay too intact and don't break down into the smooth, porridge-like consistency that defines good congee.
Can I make congee with leftover cooked rice?
Yes. Using leftover cooked rice cuts the cooking time roughly in half (30-45 minutes instead of 60-90). The tradeoff is a slightly less creamy, less smooth texture because the grains have already set and don't break down as completely as raw rice does during a long cook.
How do I make congee thicker or thinner?
The ratio of rice to liquid controls thickness. Use 1:7 for thick congee, 1:9 for medium, and 1:12 for thin, soup-like congee. You can also adjust after cooking — add hot water or broth to thin it out, or simmer uncovered on Keep Warm to thicken it through evaporation.
Why does my congee get so thick when it cools?
As congee cools, the starch molecules reform bonds (a process called retrogradation), which thickens the porridge dramatically. This is completely normal. Add hot water or broth when reheating and stir until you reach your desired consistency.
Can I cook congee overnight in a rice cooker?
Some rice cookers with a dedicated porridge timer allow overnight cooking. Without a timer, it is not recommended to leave the cooker unattended for that long. If your cooker has a delay-start timer, set it so the congee finishes when you wake up, but only use water and rice — no perishable ingredients for overnight delays.
