A slow cooker is the pinnacle of low-maintenance cooking. Place the ingredients inside, turn it on, and let it cook. No stovetop required. Your only thought is how delicious that meal is going to taste. But some slow cookers have features that make them better suited to your specific needs than other models. To be happy with your purchase, you’ll want those needs met.

The best slow cookers offer a consistent temperature through many hours of cooking. The warm setting must keep your food warm without letting it continue to cook. You’ll want a capacity that can accommodate your family’s needs, a removable inner pot that’s easy to clean, and durable construction that will allow many long years of use.

Some slow cookers have programmable features that might be of interest, as well. Before buying a slow cooker, it helps to take an in-depth look at your choices so you’re sure to get the right one.

Slow cookers were originally invented to cook dried beans. In fact, the first slow cooker was known as the Electric Bean Pot.

How we tested slow cookers

In the FranksWaffle test kitchen, we put our slow cookers through a 12-hour test regimen.

Each model was loaded with the ingredients for a savory pot roast with orange.

As the meat cooked, we assessed four performance categories: temperature, finished dish, “keep warm” function, and mobility. We then chose the top five cookers.

“Keep Warm” function

A slow cooker must be able to keep finished food warm without overcooking it.

The ideal temperature range for keeping foods warm is between 135°F and 155°F.

We tested each unit’s temperature at the one- and two-hour mark after the machine switched (automatically or manually) to “Keep Warm” to see if it adhered to our ideal.

Temperature: accuracy and constancy

Slow cookers prepare foods by braising them. Braising is the slow, low-temp method of applying heat to break down tough meat fibers and weaken vegetable cell structures.

The ideal result: moist meat and soft vegetables.

A slow cooker’s temperature shouldn’t rise above approximately 180°F. Otherwise, the outside layer of meat will overcook to the point of stringy, tasteless dryness, and the inner portion will not have cooked long enough to attain its ideal creamy softness.

Slow cooker wattage

In the FranksWaffle lab, we obtained temperature readings at the following intervals: one hour, two hours, four hours, six hours, and nine hours from the start.

We noted the pace at which each product heated up and what temperature it stayed at during the cooking portion of the test.

Testing slow cookers
We spent 184 hours researching 41 different slow cookers before choosing the best. We then hands-on tested our top model in the FranksWaffle lab.

Finished dish: taste and appearance

After the test period, we checked the meat and other ingredients for the desired fork tenderness.

Each cut of beef was considered done at an internal temperature between 155°F and 170°F.

Where different parts of the cut registered at different temps, we tested for doneness by pulling apart meat fibers with a fork.

Slow cooker weights: unfilled

We assessed the appearance of each pot roast by looking at the color of the beef, outside and in, and the condition of the accompanying ingredients.

Perfectly braised beef is dark on the outside and pink on the inside.

The taste of each finished dish was rated based on mouthfeel, texture, and whether the dish presented a pleasing combination of flavors.

Mobility

Once a dish is prepared in a slow cooker, the unit is often moved to another location for serving, such as a table or buffet.

We tested each unit for handle sturdiness, housing temperature, lid integrity, and whether liquids were prone to leak from the insert when moved.

Other features

We also considered other features and functions.

For example, some models include the ability to brown, sear, or sauté food before slow cooking.

Our researchers look for slow cookers with the versatility to make meal preparation as easy as possible.

We tested slow cookers to make sure meat was properly cooked to temperature (between 155°F and 170°F) within a 12-hour period.

Slow cookers range in capacity from 1 1/2 to 8 1/2 quarts. We tested models of varying sizes to compare their capabilities.

We look at slow cookers that can provide extra functions, like baking, to compare their versatility.

Our testers checked temperature readings at various intervals to determine the heating pace during each phase of evaluation.

Clear glass lids are great for visually checking your dish during cooking. In our testing process, we closely examined lid durability.

We evaluate slow cookers for handle sturdiness, housing temperature, and lid integrity to determine which models offer the best mobility.

Some slow cookers have the ability to brown meat or sauté food before cooking. We scrutinize this capability in the appliances that offer it.

Slow cookers are usually round or oval in shape. We look at models of both shapes to find the best in class.

We evaluate slow cookers of various capacities to find the models that are best for both small and large groups. We also determine how much space they take up in a cabinet or countertop.

What to look for when buying a slow cooker

Capacity

Slow cookers range in size from 1 1/2 to 8 1/2 quarts. Choose the right size to fit your household.

  • In general, if you’re cooking for one to three people, a 4-quart model works well.
  • For a household of four, opt for a 4- or 5-quart slow cooker.
  • If you routinely cook for larger groups, look for a slow cooker with at least a 6-quart capacity.

Shape

Most slow cookers are round or oval in shape. Both shapes work well, but the best option for your kitchen depends on what meals you like to prepare most often.

If you usually cook stews, soups, or beans, both round and oval slow cookers would suit your recipes. However, if you mainly use your slow cooker to prepare whole chickens, ribs, brisket, or other large cuts of meat, an oval shape would likely be the better option.

Lid

It’s important to keep the lid on a slow cooker when you’re preparing a meal. A clear glass lid is best because it allows you to check the progress of your food without actually removing it.

Insert material

A slow cooker’s insert is the removable pot that you mix your ingredients in.

Most inserts are made of ceramic or porcelain, but some slow cookers have a metal cooking pot.

These materials all conduct heat well, though ceramic and porcelain are usually easier to clean.

Handles

The exterior of a slow cooker often gets hot while in use, but you want to make sure that the handles never do.

Look for a model with large handles that stay cool and are sturdy so you can easily move the slow cooker to serve dinner.

Controls

Some slow cookers feature only a manual dial or knob control that allows you to set the appliance to low, medium, or high. Manual slow cookers aren’t equipped with timers, so you must keep an eye on your meal and turn the cooker off when necessary.

Other slow cookers are equipped with programmable controls. Not only can you set a digital slow cooker to low, medium, or high heat settings, you can also set a digital timer so the slow cooker turns off at a specific time. These slow cookers usually have a keep warm setting as well, so your food won’t be cold if you get home after it has stopped cooking.

Extra settings

Depending on how you plan to use your slow cooker, you may want to choose a model equipped with other cooking settings, such as those for browning, sautéing, roasting, or steaming.

Slow cookers with these extra settings are usually more costly, but if you’re making a more involved dish, they can save you from having to clean multiple pots and pans at the end of the night.

Expert tip: Look for an insert with a nonstick coating for the easiest cleaning.

How much should you spend on a slow cooker?

Slow cookers are available at a variety of price points.

In general, you can expect to pay anywhere between $15 and $150, depending on the size of the cooker and its features.

  • For a basic, mechanical slow cooker, expect to pay $15 to $40.
  • For a higher-end, programmable slow cooker, you’ll likely pay between $50 and $150.
Did you know?
You shouldn’t use frozen ingredients in your slow cooker. They can bring the cooking temperature down low enough for bacteria to grow.

Tips and tricks for using your slow cooker

  • Preheat your slow cooker before adding ingredients. Giving it 20 minutes or so to warm up before you toss in your ingredients can make a big difference in the finished product.
  • Don’t overcrowd the pot. Fill it half or two-thirds full.
  • Don’t lift the lid off your slow cooker to check on your meal. The heat will escape and slow down the cooking time. Only check on your meal in the last half-hour or so of cooking.
Browning meat and sautéing vegetables prior to slow cooking helps bring out deeper flavor and color in the finished results. For even richer flavor, consider deglazing the pan you use to brown your meat with a little stock, water, or wine.

FAQ
