Slow Cooker Sizes Guide:

The size of a slow cooker can range from 2 Quarts to 8 Quarts and come in round and oval shapes.

  • Note: 1 Quart=4 Cups

The most troublesome problem for many people when buying a slow cooker is not knowing what shape and size to choose.

The size is really important because if you want to get the best cooking results, the ingredients you put in and how you fill the slow cooker with food, matter.

When preparing a meal, a slow cooker should be filled from two-thirds to three-quarters full.

Here are two questions to consider before buying: How many people are in your household? What do you want to cook in a slow cooker?

If the budget will allow, having two sizes of slow cookers (one small and one large) is a good idea. You can make many different types of recipes at the same time. 

The size of slow cookers: 

  • 1-3 Quart: Suitable for single people or couples. It’s good for things like stewed beef (cubed), meatballs, soup, or dip. However, you cannot use it to stew a whole chicken or larger pieces of meat.
  • 4-5 Quart: Suitable for small families (couples plus a young child). You can use it to cook soup, small meat or casserole, or make desserts.
  • 6 Quart: This size is the most popular and is considered the standard size. Suitable for many dishes, including soups, stews, desserts, and casseroles. 
  • Above 8 Quart: This is most suitable for large families or for parties. Using it to stew a lot of ingredients, a whole chicken, ham, or other large pieces of meat.

Small slow cookers are generally round, while large-size slow cookers are generally oval, so you can stew the whole chicken within them.

How To Use The Slow Cooker Properly?

When you find the best slow cooker, you also need to know how to use it properly for the best result.

Here are some basic tips and precautions that should be followed when using a slow cooker: 

  • Before cooking, thaw the frozen meat in the temperature-safe zone of your refrigerator. Don’t cook frozen meat directly. Since slow cookers do not consistently get frozen meat to a safe temperature (above 140°F) evenly or quickly enough, which opens the door for bacteria to thrive.
  • Don’t overfill the pot, just fill it two-thirds full. Putting too little or too much food in the slow cooker can affect the cooking time, quality, and safety.
  • Do not open the lid during cooking, otherwise, it will lose heat and extend the cooking time. It is only advised to open the lid to add food later.
  • Don’t add too much wine or liquor. Unlike cooking with stoves and ovens, alcohol in a slow cooker is difficult to evaporate. Most of it will be absorbed by the food. The food will end up having a strong smell of alcohol, which may cover up the food’s proper aroma.
  • If there are dairy products such as milk, cheese, or sour cream in your ingredients, wait until the cooking is over before adding them to the pot. Adding them too early may cause lumps.
  • When meat and harder vegetables (such as potatoes, carrots, onions, etc.) are cooked at the same time, the vegetables should be placed under the meat, because vegetables are cooked slower than meat.
  • Tomatoes, mushrooms, zucchini, and other soft and well-ripe vegetables should be added 45 minutes before the end of cooking.
  • The best cooking time for beef is at a low temperature for 8-10 hours. The best cooking time for chicken is at a high temperature for 4 hours.
