Is the ThermoWorks Thermapen ONE worth it?

Yes, for the right buyer. The ThermoWorks Thermapen ONE ranks #1 in our Best Meat Thermometers for Deep-Frying a Turkey list (top pick). Its biggest strength: the fastest read available means less time with a probe near hot oil. The main caveat: premium price for what's used a handful of times a year around the holidays.

Overview

What the ThermoWorks Thermapen ONE does well

Best overall. 5°F accuracy across the full range. Keep in mind that premium price for what's used a handful of times a year around the holidays.

Best for spot checks. Its case rests on a 1-second check means minimal heat loss when opening the oven door and accuracy is valuable for hitting an exact doneness target on an expensive roast. The tradeoff: still requires opening the oven for every check, unlike a leave-in probe.

Thermapen ONE for grillers who want the fastest, most trusted read and don't mind paying for it. 5°F accuracy with NIST-traceable calibration.

The ThermoWorks Thermapen ONE is a solid option in its class with clear strengths and a few honest tradeoffs. It suits buyers whose priorities match its strengths above; if your needs differ, the alternatives below are worth a look.From our full ThermoWorks Thermapen ONE review

Buying advice: meat thermometers

  1. Instant-read suits steaks, chicken and spot checks. Leave-in probes suit roasts and smoking. Wireless probes suit grilling while you're away from the cooker.
  2. Good instant-read thermometers settle in about 1 to 3 seconds. Slower models need longer in the meat.
  3. Look for accuracy within about ±1°F. Test in ice water (32°F) and recalibrate if your model allows.
  4. A thin probe tip leaves smaller holes. A backlit, auto-rotating display helps at night and for left-handed cooks.
  5. Bluetooth range drops through walls and grill lids. Wi-Fi models avoid range limits but need setup.

Where can I buy the ThermoWorks Thermapen ONE?

It's sold on Amazon. Prices and stock change often, so check the current listing before you buy, our link takes you straight to it.

Should I use a leave-in probe or an instant-read for a roast in the oven?

A leave-in wireless probe like the MEATER Plus is better for roasts and whole poultry, since it tracks internal temperature continuously without opening the oven door, which drops oven temperature every time it's opened. An instant-read like the ThermoPro TP19 works too, but requires opening the oven and losing heat each time you check.

Is the MEATER Plus safe to leave in the oven the whole time?

Yes, its ambient sensor is rated to 527°F, well above any home oven's typical range, and the probe itself is designed to sit inside the meat while the ambient sensor reads the surrounding oven air. It communicates wirelessly, so there's no cable running out of the oven door that could get pinched or melt against the door seal.
