How Slow Cookers Work

Because the lid traps steam, moisture circulates inside the slow cooker, helping to tenderise meat while slowly softening vegetables.

Most slow cookers have three settings.

Setting	Typical Temperature	Best For
LOW	~175–200°F (79–93°C)	All-day cooking (8+ Hours)
HIGH	~250–300°F (121–149°C)	Faster cooking (4–6 Hours)
WARM	~165°F (74°C)	Holding cooked food

Both LOW and HIGH settings eventually reach similar temperatures, but the HIGH setting reaches that temperature more quickly.

Minimum Safe Internal Temperature

Cooking time is helpful, but the safest way to ensure food is fully cooked is by checking the internal temperature.

Food safety authorities recommend the following minimum temperatures:

Food	Safe Internal Temperature
Beef, pork or lamb	63°C (145°F)
Ground meat	71°C (160°F)
Poultry	74°C (165°F)
Soups and stews	74°C (165°F)

Using a kitchen thermometer helps ensure food is properly cooked and safe to eat. These temperatures align with USDA food safety recommendations, which are widely used as a global reference for safe cooking temperatures.

Helpful Slow Cooker Cooking Tips

Start on HIGH for the First Hour

If you are cooking a meal for a long time on LOW, it can help to start on HIGH for the first hour before switching to LOW. This helps food heat more quickly and move through the temperature range where bacteria grow most rapidly.

Keep the Lid Closed

Try to avoid lifting the lid too often during cooking. Each time the lid is removed, heat escapes and it can take around 20 minutes for the slow cooker to return to its cooking temperature.

Thaw Meat Before Cooking

For best results and food safety, thaw frozen meat before adding it to a slow cooker. Frozen meat can take too long to reach a safe cooking temperature.

How Full Should a Slow Cooker Be?

For best results, slow cookers should usually be filled between half and two-thirds full. This allows heat to circulate evenly around the ingredients while preventing food from overcooking or burning around the edges.

Should You Brown Meat Before Using a Slow Cooker?

Many slow cooker recipes begin by browning meat in a pan before adding it to the slow cooker. While this step is optional, it can improve flavour by creating a richer caramelised surface on the meat.

Browning meat also helps remove excess fat and can add depth to sauces and stews. However, if you prefer a quicker preparation, most recipes will still cook successfully without this step.

Can You Cook Frozen Meat in a Slow Cooker?

For food safety reasons, it is generally recommended to thaw meat before placing it in a slow cooker.

Frozen meat may take too long to reach a safe cooking temperature, which can allow bacteria to grow during the early stages of cooking.

For best results:

• thaw meat in the refrigerator first
• cut large pieces into smaller portions
• ensure the slow cooker is at least half full

Once thawed, meat can be safely cooked in the slow cooker using the timing guide above.

How Long Does a Slow Cooker Take to Heat Up?

Most slow cookers take around 30–60 minutes to reach their cooking temperature, depending on the model and how full the slow cooker is.

This is why many recipes suggest starting on HIGH for the first hour before switching to LOW. Heating the slow cooker quickly helps food move through the temperature range where bacteria grow most rapidly.

Common Slow Cooker Questions

Is It Better to Cook on LOW or HIGH?

Both settings will cook food safely. The difference is simply how long the cooking takes.

LOW is ideal for:

• cooking meals throughout the day
• tougher cuts of meat
• soups and stews

HIGH is helpful when you need a meal ready sooner or when cooking more delicate ingredients like chicken.

Can I Leave a Slow Cooker On All Day?

Yes. Slow cookers are designed for long cooking times and are safe to leave on for several hours while cooking meals such as stews, soups, and braised meats.

Can You Put Raw Meat in a Slow Cooker?

Yes, it is completely safe to cook raw meat in a slow cooker. Slow cookers are designed to heat food gradually while maintaining a temperature high enough to safely cook meat.

However, it is important to ensure the food reaches a safe internal temperature during cooking.

For best results:

• thaw frozen meat before adding it to the slow cooker
• cut large pieces into even sizes
• ensure the slow cooker is at least half full

Some cooks also like to brown meat before adding it to the slow cooker to develop additional flavour. This step is optional, so check the individual recipe for guidance on whether it is recommended.

Slow Cooker Conversion Chart (Oven to Slow Cooker)

One of the most common questions people ask is how to convert traditional oven recipes for the slow cooker. While every recipe is slightly different, this simple guide can help when adapting recipes.

Conventional Oven Time	Slow Cooker LOW	Slow Cooker HIGH
30 minutes	1–2 Hours	1 Hour
45 minutes	3-4 Hours	2 Hours
1–1½ hours	6-7 Hours	3-4 Hours
2–3 hours	8-10 Hours	4-6 Hours

These times are approximate but provide a helpful starting point when converting casseroles, braised meats, and stews for slow cooker cooking.
