NutriChef PKWTR40 Warming Tray Review: A simple, good-looking warmer held back by its fixed heat

A slim stainless-steel and glass warming tray built to keep buffet dishes hot rather than cook them, with a long, narrow 22.4 x 6.7 inch surface. It runs on a single on/off switch instead of a temperature dial, which makes it foolproof but leaves no way to turn the heat up.

TL;DRThe Short Answer: Is the NutriChef PKWTR40 Warming Tray Worth It?

No dial means nothing to get wrong, and also nothing to turn up. NutriChef's PKWTR40 is a 150-watt warming tray with a long, narrow 22.4 x 6.7 inch tempered glass surface rated to 203°F, and a single on/off switch with an LED indicator. It holds pre-heated food warm through a buffet or holiday meal well, especially under lids, but it will not reheat a cold dish in any hurry, and the narrow top suits a row of smaller dishes better than one big roasting pan.

NoFussDeal rates the NutriChef PKWTR40 Warming Tray 4.5 out of 5 at $69.99, compared against 4 alternatives sold on Amazon. Last updated September 27, 2026.

What Stands Out

  1. 22.4in x 6.7in non-stick tempered glass warming surface, rated up to 203°F
  2. 150W heating element on 120V power, described as low power consumption
  3. Stainless steel housing with cool-touch carry handles, 5.8 lbs total weight
  4. Simple on/off switch with LED power indicator - no adjustable temperature dial
  5. 1-year manufacturer warranty

Strengths and Drawbacks

What works

  • Keeps buffet food hot without burning or drying it out
  • Long 22.4-inch surface takes a row of smaller dishes or foil trays
  • Sleek black glass and stainless steel look that is attractive on a table
  • Cool-touch handles and a low 5.8 lb weight make it easy to carry between kitchen and buffet table
  • Simple on/off operation with no settings to figure out

What does not

  • No adjustable temperature dial; the tray has only an on/off switch
  • Uncovered food can drift toward lukewarm rather than staying hot
  • The 6.7-inch-wide surface is narrow, so wide casserole dishes overhang the heated area
  • The 3.9 ft cord is short for a buffet table, which often means adding an extension cord or power strip

Features in Depth

01

Non-Stick Tempered Glass Warming Surface

Warming surface size 22.4in x 6.7in Maximum temperature 203°F Surface material Non-stick tempered glass

The 22.4in x 6.7in heating surface is black non-stick tempered glass rated to reach up to 203°F, the same look as a glass cooktop. The long, narrow shape suits a buffet line of smaller dishes, loaf pans or foil trays; wide casseroles will overhang the heated area. The glass wipes clean with a damp cloth once it has cooled.

02

150W Heating Element

Heating element power 150 Watt Voltage 120V Power supply type Corded electric

A 150-watt element on standard 120V household power spread across the whole glass surface is a gentle amount of heat. That is deliberate: it is enough to hold hot food near serving temperature without scorching the bottom or drying it out, but not enough to bring a cold casserole up to temperature quickly. Heat food in the oven first, then move it to the tray, and keep lids or foil on to hold the heat in.

03

Cool-Touch Handles & Portable Build

Total dimensions 27.1in x 8in x 1.6in Item weight 5.8 lbs Cool-touch handles Yes

The stainless steel housing measures 27.1in x 8in x 1.6in with handles and weighs 5.8 lbs, thin enough to slide into a cupboard between holidays, with cool-touch carry handles for moving it while hot. The power cord is 3.9 ft, which is short for a buffet table, so plan on an extension cord or power strip.

$69.99 4.5/5 Check price
04

On/Off Switch with LED Indicator

Temperature control type On/off switch only LED power indicator Yes Recommended preheat time 5 minutes

Operation is limited to a single on/off switch with an LED power indicator rather than a temperature dial; NutriChef recommends preheating for at least 5 minutes before placing pans on the tray. For hosts that is a feature, with no setting to guess at, and for anyone keeping food warm on the Sabbath a fixed heat is exactly what is wanted. The cost is that you cannot turn it up for a dish that is cooling too fast.

How We Scored It

Based on
The manufacturer's published specifications and the product's live Amazon listing.
Owner rating
4.5 out of 5 on Amazon, recorded September 27, 2026
Compared against
Chefman Electric Warming Tray, Magic Mill Premium-Grade Glass Food Warmer, Giantex Buffet Server Warmer, Electric Warming Tray, on what their Amazon listings state and, where owners compared them, what those owners say.
How we score
We score each thing that comes up most in owner feedback on the NutriChef Portable Electric Food Hot Plate-Stainless. Seven things come up most in owner feedback: six draw praise and one splits opinion. Its ratings average 4.5 stars (75% five stars, 14% four, 7% three and 4% one or two), so every score starts at 90, that average on a 100 point scale. Where opinion is split, we take off 6. Where it draws mostly complaints, we take off 12. Then we read eight owner reviews in full, including the critical ones, and move the score up to 5 points either way depending on how the owners who mention it rated the product. Our overall score starts from the same 4.5 star average and loses 0.1 for each thing that draws mostly complaints, with 0.1 more when at least a tenth of ratings are one star, never more than 0.3 in all. Nothing comes off here, so it stays at 4.5. Read our editorial standards

What Buyers Say

Food stays hot without burning, the black glass looks smart on a table, and cleanup is a wipe once it cools, so most people consider it money well spent. Temperature is the divisive point: for some the fixed heat is exactly right, others wish they could adjust it, and uncovered food can drift toward lukewarm. The on/off switch also draws comment, with some wishing it sat on the front.

Setting It Up

  1. Place on a flat surface

    Set the tray on a flat, stable tabletop or countertop within reach of an outlet.

  2. Plug in and preheat

    Connect to a 120V outlet and switch it on; the LED indicator lights to show it is warming. Preheat for at least 5 minutes before placing pans on the tray.

  3. Add pre-heated food

    Place heat-resistant cookware or foil trays of food that is already hot on the tray - it works best for holding food warm rather than heating cold food.

  4. Cover dishes when possible

    Keep lids or foil on food to retain heat; covered dishes stay noticeably hotter than uncovered ones over time.

Common Questions

Does the NutriChef warming tray have adjustable temperature settings?

No, it operates with a single on/off switch rather than a temperature dial.

How long does it take to heat up food on this tray?

It is meant to hold already-heated food warm, not to heat cold food. Preheat the tray for at least 5 minutes, add food that is already hot, and keep it covered; a cold, uncovered dish can take an hour or more to warm through on a tray like this.

Is the surface easy to clean?

Yes. Wait until the glass has cooled completely, then wipe it with a damp cloth.

The Verdict

4.5Out of 5

The NutriChef PKWTR40 does the core job well: it holds pre-heated buffet food at a steady warmth on an attractive stainless steel and glass tray, with nothing to set beyond an on/off switch. The fixed 150W heat is gentle by design, so it keeps food hot without scorching it, but it will not rescue a dish that went on cold, and uncovered food cools toward lukewarm. Its long, narrow surface suits a row of smaller dishes rather than one wide casserole, and the short cord usually means an extension. If you want to fine-tune the heat, look for a tray with a temperature dial; if you want something you switch on and forget, this fits.

Who should buy it

  • Hosts keeping pre-heated dishes warm through a meal
  • Buyers who prefer a simple on/off switch over dialing in a temperature setting
  • Anyone wanting a slim, good-looking stainless steel and glass tray for a buffet or bar setup
  • Households that need a fixed, set-and-forget warmer for the Sabbath

Who should skip it

  • Anyone expecting the tray to heat cold food quickly rather than just hold already-warm dishes
  • Users needing a longer built-in cord reach without buying an extension cord

A dependable, easy-to-clean warming tray for holding buffet food hot, best suited to buyers who do not need adjustable temperature control.
