A brief history of slow cookers

Before we jump into slow cooker advantages and disadvantages, let’s a take a look at how these appliances came to be in our kitchens. Slow cookers became popular around the 1970s, when women were working more outside the home (because, well, inside the home we’ve always worked!).

They simply switched on these convenient appliances before going to work, and when they got home, the food would be ready. Just like magic!

But around the 1980s, the use of slow cookers began to decrease dramatically. It’s speculated that it may be related to the introduction of microwave ovens into the market.

Today, slow cookers are back and better than ever. I bought this slow cooker when my daughter was a couple of months old, in order to lighten the load of household chores a bit so I could spend more time with her. Working parents: I see you: I am you!

Anyways, my slow cooker has ended up being such a time saver! I’ve been able to make everything from lasagna to pizza, soups and casseroles, overnight breakfasts, baked potatoes … I’ve really put it to work! So let’s dive right in and see just how a slow cooker works, and how to cook with one of these babies.

What is the benefits of using a slow cooker?

A slow cooker can be a great addition to any kitchen, especially for busy families or those who enjoy coming home to a hot meal. While there are some slow cooker advantages and disadvantages, the benefits generally outweigh the drawbacks.

One of the main advantages of using a slow cooker is that it is very energy efficient. Slow cookers use less electricity than an oven, and they can even be used on a lower setting when cooking for longer periods of time. Additionally, slow cookers can help to tenderize tougher cuts of meat and make them more flavorful.

Another benefit of slow cookers is that they are very convenient. They can be used to cook food ahead of time, and then kept on warm until ready to serve. This is especially helpful for busy families who may not have time to cook during the week.

Finally, slow cookers are relatively inexpensive and easy to find in stores or online. While there are some disadvantages to using a slow cooker, such as the risk of overcooking food or forgetting to turn it off, these generally pale in comparison to the benefits.

For busy families or those who enjoy coming home to a hot meal, a slow cooker can be a great addition to any kitchen.

Slow cooker advantages and disadvantages

7 Main Slow Cooker Advantages

As a Registered Dietitian, many of my clients have asked me: is a slow cooker good for health? And the answer is: yes! Using a slow cooker has many advantages. Not only does it save us time spent cooking, but it also lends itself well for preparing healthy and balanced meals. Let’s check out the benefits of using a slow cooker:

1. Save time spent in the kitchen: They require just a little of your time in terms of food preparation and cooking. Yes, you have to do a little prep work, but after that, all you have to do is press a button and that’s it. The slow cooker will do the cooking for you and you no longer have to worry about “what am I going to cook when I get home from work and can barely stand up?”

2. Provide consistent cooking results: Since food cooks slowly and at a stable temperature, it’s less likely to burn in a slow cooker. The cooking results with these appliances are pretty consistent.

3. Save food dollars: They’re a great option for cooking less expensive cuts of meat. These cuts tend to have a lot of connective tissue and collagen; thus, they’re usually tough. When cooked slowly, at a low temperature and with enough liquid, the meat is so tender that it falls off the fork.

4. Save time: They save time in terms of dishwashing, since everything is cooked in one container. This advantage also helps to save on electricity, since there aren’t multiple appliances on at the same time. Plus, slow cookers use less electricity than ovens.

5. Reduce heat: They generate almost no external heat; it stays concentrated inside the pot. And I don’t know about you, but with the heat lately where I live, cooking in front of a hot stove doesn’t appeal to me much!

6. Convenient: They come in different sizes to better match your personal needs. They’re also available at different price points, depending on your budget.

7. Portable: A slow cooker also travels well. Take it from your kitchen to a family gathering or a party. Just plug it in and serve.

4 Main Slow Cooker Disadvantages

There are a few factors to consider when using or investing in a slow cooker. It’s important to be aware of them for better planning when it comes to cooking.

1. Power supply considerations: If there are frequent fluctuations in the electrical power system, the cooking process may be affected. Depending on the slow cooker you have, it may not automatically turn back on when the service is restored, or it may stay in “Warming” mode.

2. Meal planning beforehand: Planning is required before cooking. For example, you have to know what exact ingredients are going to be used and pre-prepare them properly. You also have to defrost meats well so that they cook completely. Finally, you may have to stick to specific recipes and cooking times (there aren’t many chances for improv when it comes to slow cooking). Not all dishes are suitable for this cooking method.

3. Nutrient retention: One common question I get asked is: Do slow cookers destroy nutrients? Well, there are foods like vegetables that can lose nutrients when subjected to prolonged heat. However, most of those nutrients remain in the sauce or liquid in which the food was cooked. You can also add them at the end of the cooking time, which also helps retain their texture and additional nutrients.

4. Food texture changes: Canned foods, such as vegetables, can become too mushy in a slow cooker. It’s better to use them fresh or frozen. But, frozen veggies tend to make the texture of the dish more “watery”. Defrosting and draining the extra liquid before cooking can help minimize this.


How does a slow cooker work?

How does a slow cooker work
One of the best slow cooker benefits is that everything is cooked in the same place, which means: less dishes to wash!

Slow cookers are as easy to use as just pressing a button. Literally! These appliances cook similarly to how we cook on a conventional stove: the heat begins to rise from the base of the container to the sides, heating up the food inside.

The difference is that with a slow cooker, the food is cooked in a removable ceramic or stoneware container. This container is inside a metal base which creates heat and controls the cooking temperature. The steam that is generated inside the pot helps keep the food juicy. That’s why slow cookers are excellent for stewed and braised dishes. And slow cookers can also be used for baking as well.

Additional slow cooker functions

In addition to being able to cook a full meal at the touch of a button, many slow cookers also have a Warming mode. This option allows you to keep your food at an optimal serving temperature once it’s cooked. However, it should be mentioned that if you leave it on Warming for too long, the food will continue cooking and may become overcooked.

There are models that also have an AUTO mode, which is useful to cook foods that are very cold, or even frozen (however, it’s NOT recommended to cook frozen meat in the slow cooker since it won’t cook properly). During its first hour of operation, the slow cooker will cook at a high temperature, then go to a lower setting, until cooking is complete. Cool, right?

An additional function, but available only on certain models, is the programmer. This operation varies depending on the brand, but its use is the same: to program the cooking time and shutdown once it’s done. This is super convenient for people who are away from home for long periods of time and can’t manually turn off the slow cooker.

Are slow cookers safe?

In short, yes – with certain precautions. Many people may ask: Can slow cookers catch fire? Slow cookers are designed to run all day unattended without posing a fire hazard. However, there are some measures you can take to improve the safety of doing so:

  • Always place your slow cookers on top of a flat surface where there’s no danger of it tipping over.
  • Make sure flammable objects are not left touching or too near the slow cooker.
  • Move the slow cooker away from the wall and any curtains.
  • Always have a working smoke alarm and electrical safety switch in your home so that if you are home, you and your family can be alerted in case something happens.

Does slow cooker use much electricity?

One question people frequently have about slow cookers is whether they use a lot of electricity, especially since they’re operating for long periods of time. However, this appliance requires only a small amount of electricity only to do its work . Compared with a standard oven, a slow cooker uses a lot less energy, and it won’t heat up an entire kitchen the way an oven does.

According to this article, “Modern slow cookers consume as little as 150 Watts per hour at Low setting. So in 6 hours on a low setting, the total use is 900 -watt-hours. This is a much lower consumption than an electric stovetop or an oven needs to get a meal cooked. Even a pressure cooker will consume much more electricity”.

It also mentions that “The average electricity rate in the US is 13.19 cents per kilowatt-hour (kWh). So the electricity cost of cooking a meal in an average-sized slow cooker is just around 20 cents”. So there you have it: another one of the best slow cooker benefits is that they’re not just healthy, they’re energy efficient as well!

How to use a slow cooker in 3 easy steps

How to use a slow cooker
Slow cookers may come with manual control dials or a digital programmer

The use of these appliances varies a little depending on the food we are preparing, and the particular model, but in general terms, the steps to cooking with a slow cooker are pretty basic:

  1. Do all your ingredient prep: This may include chopping, slicing, mixing, pre-cooking certain meats, seasoning, or marinating.
  2. Place the ingredients inside the cooking insert: Depending on the recipe, there may be some ingredients that need to be added at the end of the cooking process to avoid overcooking them. For example: vegetables, cheeses, pasta and fresh herbs.
  3. Program the cooking time: This will vary according to the recipe. I recommend (in capital letters) using a slow cooker that is programmable. Those that have manual controls don’t offer as much freedom. The programmable cookers automatically turn off when the cooking time ends and/ or keep cooked food at a safe temperature. So, all you have to do is enter the cooking time and temperature, turn it on and go! Continue about your day, and once you’re home, your food is ready!
