How to Use a Meat Thermometer Accurately

How to Use a Meat Thermometer Accurately

Working out how to use a meat thermometer accurately might sound simple, but it can be surprisingly easy to do incorrectly. Ensuring that readings are taken properly is essential for making sure that your food is perfectly cooked, safe and delicious, every time.

How you use your food thermometer to take a temperature will depend on the type of food you are measuring, and how accurate you need it to be. For example, it’s really important to take an accurate reading when cooking a medium rare steak to ensure it’s spot on, whereas soups and reheated foods require less accuracy because they only need to reach 74°C or higher.

Read on to learn how to use a meat thermometer to take the temperatures of different types of food.

Key Temperatures for using a meat thermometer

How to use a meat thermometer to measure the temperature of a piece of meat.
1. How to use a meat thermometer for solid foods

Whether heating or cooling solid food, the centre of the thickest portion will be the slowest to change in temperature. Therefore, this is the area you will need to measure to ensure it has fully cooked or cooled. To locate the centre of a food such as a piece of meat, use your thermometer to slowly insert the probe into the meat and watch how the temperature drops as you approach the centre, before rising again as you move past it. This will help you to locate the lowest temperature of the meat, ensuring that this reaches your safe or desired temperature.

Spot check large pieces of meat

When measuring the temperature of whole birds, like chicken, you want to put the thermometer probe in the thickest part, where the breast meets the thigh. Meat like this will usually vary in temperature considerably throughout, providing very different readings in the legs to the breast. It’s a good idea to spot check large pieces of meat to ensure they have come to temperature all over, while also trying to avoid bones or gristle as this can provide an inaccurate reading.

For smaller, thinner pieces of meat

Such as burgers, steaks and chicken breasts or wings, it’s important to make sure that the probe does not go all the way through the meat and onto the surface beneath. Holding the meat between a pair of tongs while using your meat thermometer to take the temperature from the side instead of above can help to prevent this. Our Thermapen thermometers feature a type K thermocouple probe that only needs to be inserted 3 mm into foods to get an accurate reading, making them ideal for smaller cuts of meat.

2. How to use a food thermometer for liquid foods

Taking an accurate temperature reading of liquid foods is slightly different to solids because they heat and cool by convection rather than conduction. Therefore, it’s not simply a matter of taking a reading from the centre, but by checking the liquid as a whole. The best way to do this is by stirring the liquid first, and then stirring the thermometer probe through the liquid, watching the temperature change as it moves through the food.

If you’re using a leave-in meat thermometer for oven roasting your Sunday lunch or smoking meat on the BBQ, you’ll need to insert your thermometer probe in exactly the same way, aiming for the thickest part and avoiding bones or gristle. Once you receive an alert to confirm that your meat is cooked, we recommend also using an instant-read thermometer to spot check the meat all over.

Why response time affects how to use a food thermometer

Different thermometers take varying lengths of time to settle on a reading. When using a meat thermometer with a slower response time, remember to give it time to provide an accurate reading. For thermometers with fast response times, such as our Thermapen One which reads the temperature in one second, it’s good to remember that often the food itself is changing in temperature as the thermometer is reading it. Therefore, a change in readings is simply a reflection of the food continuing to cook, even if it’s off the heat.

Top 3 thermometers for USING TO COOK meat
Thermapen ONE

The Thermapen One is the ultimate kitchen thermometer for the cook who knows that temperature, not time, is key to creating perfectly cooked food. With one second readings, it’s perfect for cooking steaks and other meats where they can become overdone in an instant, as well as spot checking larger joints to ensure they’ve come to temperature throughout. Not only is the Thermapen One ideal for meat, it can also be used for baking, confectionery and even reheating your leftovers and daily meals. It’s an essential tool in any kitchen.

DOT Digital Oven Thermometer

The DOT is perfect for cooking large joints of meat over long periods of time, without having to keep going back to your oven or BBQ to check the internal temperature. Simply set your desired temperature and wait for the alarm to sound. Voila, your Sunday roast will be perfectly done!

Smoke Wireless Barbecue Thermometer

The Smoke is for BBQ enthusiasts who like their meat cooked low and slow. With a probe for your meat and a probe for your pit, you have ultimate control over keeping your cook on track.
