Rice Cooker Meal Prep: How Much Rice to Cook for the Week
Quick answer: For a week of lunches, cook 4 to 5 cups of dry rice (about 12 to 15 cups cooked) in a large rice cooker, cool it quickly in shallow containers, and refrigerate it within an hour or two. Eat refrigerated portions within 3 to 4 days, and freeze the rest for later.

Meal prep steps
- Cook the rice and let it rest 10 minutes.
- Fluff and spread it into shallow containers so it cools quickly. Do not leave it in the pot on the counter.
- Refrigerate within about an hour or two of cooking.
- Portion into single-serve containers or freezer bags and label with the date.
- Eat refrigerated rice within 3 to 4 days. Freeze anything you will not eat in that time.
- Reheat until steaming hot, adding a splash of water. Reheat only once.
Rice types that meal prep well
- Brown rice: holds its texture well when reheated. See brown rice in a rice cooker.
- Basmati and long-grain: stays separate and reheats nicely.
- Jasmine: works, but is softer.
- Sushi rice: hardens in the fridge and is best fresh.
Make it a full meal
Pair rice with a protein and vegetables you can steam in the same cooker. See how to steam vegetables in a rice cooker and what else you can cook in a rice cooker.
Gear that helps
Look for stackable, microwave-safe containers such as glass meal prep containers, and a quart freezer bag set for flat freezing. If you cook large batches often, a bigger cooker helps: see our best rice cookers.
Frequently asked questions
How long does meal prep rice last?
Up to 3 to 4 days in the fridge by USDA guidance, though some agencies advise 1 day. Freeze portions for longer storage.

Why is my meal prep rice hard?
Chilled starch firms up. Add a splash of water and cover while reheating.
