Best Deep Fry Thermometers for Oil, Fryers and Turkey Frying

The best deep fry thermometer for most home fryers is a clip-on model with a stem long enough to reach deep oil. For tall turkey pots, the Bayou Classic 12 in. is our top pick. However, the right choice depends on your pot depth, your top temperature and whether you want a dial or a digital display.

In short: pick the Bayou Classic 12 in. for turkey pots, the King Kooker SI5 for smaller pots, and the TempPro TP511 for a digital alert.

The 7 Best Deep Fry Thermometer Picks, Reviewed

Above all, each pick below can sit in hot oil or beside it. First, we cover long-stem dials for tall pots. Next come shorter dials, then digital models.

Best for Turkey Fryers

1. Bayou Classic 12-Inch Stainless Steel Fry Thermometer

Bayou Classic Cooking Thermometer 12"

Check Price on Amazon

Best for: Deep turkey fryer pots where a short stem would sit too high.

Above all, the Bayou Classic 12 in. fry thermometer is our best deep fry thermometer for tall turkey pots. First, the long stem lets the tip sit well down in the oil while the dial stays above the rim and away from the heat. In addition, the face is covered by tempered glass, which keeps oil spatter off the dial.

A retailer description lists a 50 to 400 F range and a red zone from 360 F. In fact, that range covers normal frying and the usual turkey target. However, the listing does not mention a clip, so plan on a pot hook or a steady hand. Also, check the scale before you rely on the red zone, because turkey guidance and fryer manuals differ on the target. For the safe oil temperature itself, see the USDA notes below.

• Stem: 12 in., stainless steel
• Range: 50 to 400 F, per a retailer listing
• Face: tempered glass over an analog dial
• Scale marks a red zone starting at 360 F, per the listing
• Fahrenheit scale

Skip it if: you fry in a shallow pan, where a 12 in. stem is too long.

Best Short-Stem Clasp

2. King Kooker SI5 5-Inch Deep Fry Thermometer

King Kooker SI5 5-Inch Deep Fry Thermometer

Check Price on Amazon

Best for: Home fryers and stockpots that are not very deep.

Overall, the King Kooker SI5 is a compact dial thermometer for everyday frying. Because the probe is only 5 in. long, it suits Dutch ovens, countertop pots and mid-size fryers. Meanwhile, the clasp hooks onto the pot wall, so the thermometer stays put while you handle food.

Specifically, retail pages for this model list the 5 in. probe and the clasp, but they do not state the temperature range. Therefore, check the dial face when it arrives and confirm it covers your recipe. Also, a short probe can sit close to the pot wall, so keep the tip in the oil and away from the metal.

• Probe: 5 in., per Tractor Supply and Home Depot listings
• Clasp that attaches to the pot side
• Analog dial
• Temperature range is not stated on the retail pages we checked

Skip it if: you fry a whole turkey, since a 12 in. stem reaches deeper.

Best Paddle Style

3. Taylor 5983N Candy, Jelly and Deep Fry Paddle Thermometer, 12 in.

TAYLOR Candy/Jelly Deep Fry Thermometer 5983N 5983N 77784059838

$14.26

Check Price on Amazon

Best for: Cooks who want a long, flat stainless paddle with a sliding clip.

Next, the Taylor 5983N is a 12 in. stainless paddle thermometer. Unlike a round dial, the paddle keeps the scale in line with the stem, so it is easy to read from a standing position. In addition, the insulated handle keeps your hand away from hot metal, and the sliding clip sets the depth.

A retailer listing gives a 100 to 400 F range with accuracy within 2 F. As a result, it covers most pan and pot frying. However, it stops at 400 F, so confirm that your fryer manual stays below that. Also, the listing says not to immerse it or use a dishwasher. We cover its candy use in our best candy thermometer guide.

• Range: 100 to 400 F, per a retailer listing
• Accuracy: within 2 F, per the listing
• Length: 12 in., stainless frame with an insulated handle
• Sliding pan clip and hanging loop
• Do not immerse it or use a dishwasher

Skip it if: you need to read temperatures above 400 F.

Best Wide-Range Dial

4. Taylor Professional 6084J8 Candy and Deep Fry Dial Thermometer

Taylor Professional Candy/Deep Fry Thermometer 6084J8

$23.60

Check Price on Amazon

Best for: Cooks who want a rugged dial with a higher top temperature.

Overall, the Taylor 6084J8 has a round 2 in. dial and an 8 in. stainless stem. For deep frying, the main draw is its wider range. A retailer listing gives 50 to 550 F, so it has headroom above typical frying temperatures. Also, it has a pan clip for hands-free use.

The same listing states accuracy within 5 F, which is looser than some picks here. However, the FAQ says you can recalibrate it in boiling water, and that is a handy fix. The listing also says to keep the head out of the liquid and out of the dishwasher. Therefore, mind the depth in a pot that is nearly full.

• Range: 50 to 550 F, per a retailer listing
• Accuracy: within +/-5 F, per the listing
• Stem: 8 in., stainless steel, with a pan clip
• 2-in. analog dial; recalibratable
• Keep the head out of the oil

Skip it if: you fry in a tall pot, where an 8 in. stem may be too short.

Best Digital with Alert

5. TempPro TempDip Elite TP511 Programmable Digital Candy and Deep Fry Thermometer

TempPro TempDip Programmable Candy Thermometer with Pot Clip

$29.99

Check Price on Amazon

Best for: Cooks who want a digital reading and a flashing alert at the target.

The TempPro TP511 is the digital pick for cooks who want a clear number. For example, you can set a target temperature, and the backlight flashes when the oil reaches it. As a result, that helps when you are lowering batches in and out and cannot stare at the display.

Specifically, TempPro’s page lists a -58 to 572 F range, an adjustable pot clip and an IPX5 splash rating. Also, the 8 in. stainless probe is long enough for most home pots. However, the manufacturer page gives two accuracy figures, so run a boiling water check before you trust it. For more on this model, see our best candy thermometer guide.

• Range: -58 to 572 F (-50 to 300 C), per TempPro
• Accuracy: up to +/-1.8 F (+/-1 C) in the specifications section
• Probe: 304 stainless steel, about 8 in. (205 mm), with an adjustable pot clip
• Programmable target with a flashing backlight alert
• IPX5 splash rating; 1 AAA battery included

Skip it if: you need a 12 in. stem for a deep turkey pot.

Best Simple Digital

6. TempPro TempDip TP510 Digital Candy and Deep Fry Thermometer with Pot Clip

TempPro TempDip 1 Sec Digital Candy Thermometer with Pot Clip & 1…

$21.99

Check Price on Amazon

Best for: Frying in pans and Dutch ovens with a plain digital readout.

In short, the TempPro TP510 is the simpler digital option. It has the same wide range and pot clip as the TP511, but it has no alert. Therefore, it fits cooks who just want a quick, readable number during pan frying.

TempPro’s page says the head rotates 90 degrees, and the LCD is backlit. In addition, the page lists IPX5 splash resistance. However, the page and the Amazon title describe the probe length differently, so check the listing if depth matters to you.

• Range: -58 to 572 F (-50 to 300 C), per TempPro
• Accuracy: up to +/-1.8 F (+/-1 C) in the specifications section
• Backlit LCD; the head rotates 90 degrees
• Pot clip; no alarm
• IPX5 splash rating; 1 AAA battery included

Skip it if: you want a target alert or a long turkey-pot stem.

Best Instant-Read Check

7. Cuisinart LCD Digital Instant-Read Thermometer

Cuisinart LCD Digital Instant Read Thermometer, Water Resistant M…

$19.77

Check Price on Amazon

Best for: Spot-checking oil, then food, with one fast digital probe.

Finally, the Cuisinart LCD is an instant-read thermometer rather than a clip-on fry gauge. Its listing names oil frying among its uses. For instance, it works well for a quick check of oil in a pan, or for taking the temperature of fried food once it is out of the oil.

Specifically, the listing gives a -58 to 572 F range, a 2 to 3 second response and an IP66 rating. It also mentions a calibration setting. However, the probe has no clip, so you must hold it near hot oil. Therefore, use long tongs or a clip-on gauge for the main reading, and treat this as a second check.

• Range: -58 to 572 F (-50 to 300 C), per a retail listing
• Response: about 2 to 3 seconds, per the listing
• Water resistance: IP66, per the listing
• Calibration setting and MAX/MIN function
• No pot clip is described

Skip it if: you want a hands-free gauge on the pot, since this one is handheld.

How We Chose the Best Deep Fry Thermometer

First, these picks are research-based. We did not run hands-on tests. Instead, we compared manufacturer pages, retailer spec listings and USDA frying guidance. Specifically, we looked at five things.

• Stem length: 5 in. for shallow pots and 12 in. for tall fryers.
• Range: it should reach at least 400 F (204 C) for normal frying.
• Mounting: a clip or clasp, so the gauge stays put.
• Readability: a clear dial or backlit display.
• Brand and fit: established makers, with no more than two picks from one brand.

Also, we only state specs that we found on a manufacturer page or a retail listing. However, where a page left a spec out, we say so. Meanwhile, our best food thermometer guide covers meat and general cooking.

Stem Length: Match the Gauge to Your Pot

To begin, stem length is the first choice to make. A short stem in a deep pot leaves the tip near the surface, and surface oil can run cooler than the middle. By contrast, a very long stem in a shallow pan can tip the pot.

In every case, aim for the middle of the oil. In fact, the pot bottom and walls run hotter than the oil itself. Therefore, a tip that touches metal reads too high.

Deep Fry Oil Temperatures by Food

USDA’s deep fat frying page lists these oil temperatures and times. We also added the Celsius values.

However, treat these as starting points. In any case, your fryer manual and recipe come first. Older USDA material used 350 F for turkey, so check which figure your fryer maker prefers.

Turkey Fryer Safety Rules

A thermometer helps you stay in control, but it does not make frying risk-free. USDA’s archived deep fat frying fact sheet gives several rules.

• Fry outdoors: choose a safe, open location.
• Never leave hot oil unattended: USDA says this on its current page too.
• Thaw fully: use a completely thawed turkey that is not stuffed.
• Do a water test: measure how much oil the pot needs before you heat it.
• Keep water away: water and hot oil do not mix, so keep a fire extinguisher nearby.

Finally, check the bird with a food thermometer. USDA says the thickest breast, innermost thigh and wing should reach 165 F (74 C). Also, do not test while the food is submerged in hot oil.

Frying Temperature Converter

Also, use this converter to switch between Fahrenheit, Celsius and Kelvin.

How to Use the Best Deep Fry Thermometer Step by Step

Indeed, good technique matters as much as the tool. Follow these steps for any model in this guide.

1. Test it first: Hold the tip in boiling water for a minute or two. At sea level, it should read about 212 F (100 C). Then note any difference.
2. Pick the pot and the spot: Use a pot deep enough that the oil stays well below the rim. Next, choose a clip spot away from the burner flame.
3. Clip it on cold: First, attach the thermometer before you heat the oil. Also, keep the tip in the middle of the oil, off the bottom and the walls.
4. Heat slowly: Next, raise the heat gradually and watch the reading. Oil can overshoot quickly, so ease off before the target.
5. Hold the target: Then adjust the burner in small steps. Also, expect the oil to drop when you add food, so give it time to recover between batches.
6. Lower food gently: Then lower food slowly to limit splashing. For a turkey, turn the burner off first if your fryer manual says to.
7. Cool and store: Afterward, let the oil cool fully before you move it. Finally, wipe the stem and store the thermometer dry.

Calibrate Your Best Deep Fry Thermometer

Indeed, gauges drift over time, and some start out a few degrees off. For example, the Taylor 6084J8 lists accuracy within 5 F, while the Taylor 5983N lists within 2 F. A quick boiling water test shows where yours stands. Because the boiling point drops with altitude, expect a lower reading in the mountains.

Next, if your gauge reads off, you can often adjust it. Otherwise, add or subtract the difference when you set your target. Our best candy thermometer guide explains the boiling water test and altitude correction in more detail.

Best Deep Fry Thermometer FAQ

What is the best deep fry thermometer for a turkey fryer?

For tall turkey pots, a 12 in. stem is the best deep fry thermometer style, because the tip reaches deep oil while the dial stays above the rim. The Bayou Classic 12 in. and the Taylor 5983N both fit this need. Also, confirm the range covers your fryer manual.

What temperature should deep frying oil be?

In general, it depends on the food. USDA lists 375 F for turkey and chicken pieces, 350 F for chicken fingers, and 320 F for fish fillets and shrimp. Therefore, always check your recipe and fryer manual for the exact target.

How deep should the thermometer probe go into the oil?

First, place the tip in the middle of the oil, away from the pot bottom and walls. The bottom and sides run hotter than the oil. As a result, a tip that touches them reads too high.

Can I use a candy thermometer for deep frying?

Often yes, since many candy models also read frying oil. However, check that the range reaches your target and that the stem is long enough for your pot. For example, the TempPro models here read up to 572 F. Our best candy thermometer guide covers the sugar side.

Why is my thermometer reading different from the fryer dial?

Because dials and probes read at different spots, either can drift. In short, test both in boiling water, which reads about 212 F (100 C) at sea level. Then trust the one that matches.

How do I check my gauge for accuracy?

First, hold the tip in boiling water for a minute or two without touching the pot. At sea level, it should read about 212 F (100 C). If your model can be recalibrated, then adjust it by the difference.

Is a digital or analog gauge better?

First, analog dials need no battery and handle heat well. Meanwhile, digital models give a clear number and often an alert. In short, choose analog for simple pots and digital for alerts. Our best analog thermometer guide explains dials.

How long should the stem be?

A 5 in. stem suits shallow pots and Dutch ovens, while a 12 in. stem suits tall fryers. In general, the tip should sit in the oil while the head stays above the rim.

Can I leave the thermometer in the oil all the time?

In fact, many are designed to clip on and stay in the oil while you fry. However, instant-read probes are not meant to stay in, so hold them only briefly. Also, never leave hot oil unattended, as USDA advises.

How do I clean it after use?

First, let the oil cool. Then wipe the stem with warm soapy water and a cloth, and keep the head dry. Do not put it in the dishwasher unless the maker says it is safe.

Bottom Line: Our Best Deep Fry Thermometer Pick

For tall pots, the Bayou Classic 12 in. is the best deep fry thermometer to start with. It has a long stem and a glass-covered dial. If you fry in smaller pots, choose the King Kooker SI5. If you want a digital alert, choose the TempPro TP511. Whichever you buy, test it in boiling water first.
