For cooking oatmeals, you can use rice cookers, slow cookers, or pressure cookers. Other than cooking raw oats or steel-cut oats with these appliances, you have the freedom to cook rice, quinoa, and wheat porridge. After extensively researching and thoroughly reviewing over 30 popular brands, we’ve come with the 9 best oatmeal cookers. The list is based on features, performance price, and the recipes you can make using these cookers.

Best Oatmeal Cooking Method

No matter if you want to cook raw oats, rolled oats, or steel-cut oats, their method of cooking is the same. First of all, measure the oats and ingredients with the ratio of 1:2. Note: If you like savory, use vegetable or chicken stock. If you want to make it sweet, use milk or a mixture of water and milk. Boil water/milk (whatever the ingredient you use), then add oats and reduce the heat to a low flame. Cover and cook until the oats soak up all the liquid. Season it at per taste and preference.

What We Don’t Like

  • Less capacity
  • Voltage issues

The Aroma ARC-994SB is the best rice and oatmeal cooker featuring 7 preset settings and digital controls to cook not just oats but also rice, quinoa, porridge, and any other cereal of your choice. If you are creative in trying different recipes, this model is a complete meal cooker for your needs.

I was impressed with its one-touch digital controls. The Keep Warm feature automatically turns off the appliance when the cereal is cooked which prevents food burning and keeps the cooked meal warm for serving. The two other features I like are Delay Timer to cook food according to a scheduled time and the Slow-Cook to prepare soups, stews, and slow-cooker beef recipe.

The ARC-994SB comes with extra accessories including a steam tray, and a spatula to conveiently cook cereals and grains. Apart from all of its positives, I was disappointed with its 4 quarts capacity of uncooked rice capacity making it a wrong option for making potluck dinners, or potluck side dishes.

Overall, the Aroma ARC-994SB is an ideal cereal cooker for small families. From cooking rice, and oats, to vegetables, and meat this model delivers complete meal options.

  • Easy-to-read digital display
  • Timer settings to schedule cooking

What We Like

  • 3D heat system to cook cereal evenly

What We Don’t Like

  • Porridge cooks to a watery consistency
  • The cord is not retractable

Featuring Japanese 3D steam technology the Toshiba TRCS01 keeps the steam to make the perfect fluffy oats. Besides, you can also prepare cereals like oat porridge, wheat porridge, quinoa and rice.

Thanks to its Preset cooking settings, especially the Quick cook mode the TRCS01 reduces the cooking time to a mere 30-minute window. When the cereal is ready, the Keep Warm feature shuts off the cooker yet keeps food warm for the next 24 hours. The best thing is its lightweight design which lets you carry this cooker for picnics or camping tours.

While testing, I observed that sometime the oat porridge gets watery due to improper settings. So it is recommended to carefully select the settings and take care of the cereal-to-water ratio. Another issue is its not-retractable short cord which becomes an issue for people with small kitchens and compact counter spaces. Overall, I recommend Toshiba TRCS01 cooker due to its endless meal options, combined with time-saving and convenient cooking.

The Hamilton Beach 37571 is the best oatmeal cooker and food steamer you can use to cook oats while you are away. Built for smart cooking purpose, it comes with a capacity of 4.5 quarts or 10 cups of cooked oats. It is best for making small potluck meals for family festivities like Easter potluck.

With 14 preset settings, you can not just prepare simple oatmeal porridge or white rice, but also go for steamed vegetables, steamed chicken, crockpot beef stew, and broth. And it is not just for steel-cut oats or instant oats. With the setting of white rice, you can also cook rolled oats and achieve a morning breakfast cereal.

Besides, Hamilton Beach 37571 also comes with a steam basket you can use for rinsing rice, cooking one-pot pasta, quinoa, or sautee meat. However, what I disliked was that its saute mode overheats the unit and any negligence may even burn the cooker. Second, the stay warm feature is comparatively less efficient than the Toshiba TRCS01. In my case, the rice were burnt when I left this cooker to stay warm mode.

Another thing that came up while testing Hamilton Beach 37571 was that it takes almost one hour to cook oats. However, if you soak your oats in warm water for an hour before cooking, the cooking time reduces considerably.

It is more than a rice cooker that you can use to cook pasta, soup, stew, oatmeal, and quinoa.

As for design, it is available in different colors, but I have white to match its with my kitchen decor. Its compact size also takes up a little space on my kitchen counter.

As the name suggests the DASH Mini rice cooker is ideal for couples. The downside is that the pan produces a terrible smell while cooking which can be resolved by buttering the pan before cooking.

Best Instant Pot: Instant Pot Pro

Instant Pot Pro - 6 quarts
Instant Pot Pro – 6 quarts

Features & Specs:

  • Capacity: 6 Quarts
  • Power: 1200W
  • Material: Stainless Steel
  • Nonstick coating
  • Dimensions: 13″ x 12.7″ x 12.8″

What We Like

  • Multi-purpose cooker
  • Ceramic non-stick coating
  • Best Compact design for travel
  • Quickly heats up for quick food preparation

What We Don’t Like

  • Small capacity
  • Not a durable build

With Instant Pot Pro, you can make healthy and delicious oatmeal recipes in no time. Thanks to its nonstick cooking pot and dual power setting options, you can cook oats, rice, vegetables, pasta, steamed chicken, etc.

What I like about this cooker is its timer settings and the nonstick coating to prepare healthy, low-fat foods. With the nonstick coating it becomes easier to clean the pot as no food gets stuck to the base.

Its convenient size fits in small spaces. So, if you feel that the COSORI 5-quart Rice Cooker is too big for the countertop, you can replace it with a Instant Pot Pro.

As for the downsides, I noticed that the Instapot Pro’s silicone gasket can sometimes fail to seat properly, causing pressure issues and delays in cooking. Secondly, its stainless steel pot builds up starch while cooking rice, requiring extra cleaning effort.

Takeaway: While the Instapot Pro is an effecient cooker for overnight oats, it requires careful maintenance and cleaning for optimal performance.

Things to Consider While Buying An Oatmeal Cooker

Before you go out and buy a cereal or rice cooker, consider the following points and keep in mind your individual preferences and your budget.


The first thing to look for in any cereal cooker is its capacity. Most of the models range from 2-8 quarts capacity. A 2-quart appliance will suffice a small family, a camper, a student, or an RV owner. However, with more members and a busy schedule, you’ll require a cookpot over 6-quart capacity.

Considering the features, I recommend going for the Crockpot Portable 7-Quart Slow Cooker, which can hold up to 20 cups of uncooked rice. With its big cooking pot, you can make a large batch of soups and stews for a family dinner.


An oatmeal cooker should be equipped with different preset time and temperature settings to cook more than one cereal like white and brown rice, quinoa, steel-cut oats, rolled oats, soups, etc. Remember that the Steel-cut oats take longer to cook than rolled ones. I would recommend Hamilton Beach 37571 in terms of multipurpose cooker with 14 preset settings.

Ease of Cleaning

Homemakers do not spend as much time cooking as they do cleaning the mess which is why an oatmeal cooker should come with a nonstick cooking pot for easy cleaning. Even, the components should be dishwasher-friendly. For this purpose I recommend buying Aroma Housewares ARC-994SB thanks to its stainless steel exterior that can be wiped with a damp cloth.


If you are low on budget, you can choose a cooker with a smaller capacity. On our list of oatmeal cooker, the best budget options are COMFEE’ 6-in-1 Stainless Steel Multi-Cooker and Hamilton Beach 37571.
