Masterbuilt 40-Inch Electric Smoker Review 2026

Our Verdict

After eight cook sessions spanning two overnight pork shoulder smokes, a four-rack capacity test, and a batch of smoked chicken thighs, the Masterbuilt 40-Inch Digital Electric Smoker earns a 4.3/5 — the most consistent, lowest-effort smoker we've tested, genuinely built for anyone who wants smoked food without managing fire, fuel, or flame of any kind.

This is the smoker we recommend for beginners, apartment or condo patio owners where open flame may be restricted, and anyone who prioritizes hands-off consistency above all else.

Bottom line: At $349–$399, the Masterbuilt 40-Inch trades smoke intensity for the tightest, most repeatable temperature control we've measured on any smoker — a fair trade for a lot of home cooks.

Who Tested This Smoker

This review was conducted by Marcus Reilly, SmokyHQ's Head Pitmaster and a KCBS Certified Judge with 15 years of competition BBQ experience. Testing ran over three weeks on a standard concrete patio installation, using a standard 120V outlet and wood chips. Eight cook sessions were logged:

• Two overnight pork shoulder smokes at 225°F, tracking temperature drift and power draw
• Four-rack capacity test with two pork shoulders and two racks of ribs simultaneously
• Batch of smoked chicken thighs at 250°F
• Built-in meat probe accuracy check against a separate calibrated thermometer
• Cold-morning start test at 36°F ambient temperature
• Windy-condition heat retention test (sustained 15 mph gusts)

What Is the Masterbuilt 40-Inch Digital Electric Smoker?

An Electric Alternative to Fire-Based Smoking

The Masterbuilt 40-Inch is a vertical cabinet smoker that uses an electric heating element instead of propane, charcoal, or wood pellets, with a side-loading wood chip tray for genuine smoke flavor. It's built around four chrome-coated cooking racks inside an insulated, double-wall steel cabinet, controlled entirely through a digital panel with a built-in meat probe.

The full spec sheet:

Why the Electric Design Matters

No Fire Management At All

Unlike gas, charcoal, or even pellet smokers, there's no ignition sequence, no fuel bed, and no flame to manage. You plug it in, set the digital dial, and insert the meat probe — the entire fire-management learning curve that trips up most beginners simply doesn't exist here.

Where It's Genuinely Useful

Electric smokers are also the only realistic option in some living situations. Many apartment and condo policies restrict or ban open-flame cooking on covered balconies, and an electric smoker is often the sole permitted way to smoke food in those settings — always confirm your specific lease and local fire code before assuming this applies to you.

How We Tested

Our three-week testing protocol for the Masterbuilt matched our standard dedicated-smoker review process:

Assembly and Burn-In

Full assembly timed from unboxing to first light took our tester 40 minutes solo with a screwdriver — among the fastest assemblies of any smoker we've reviewed — followed by a standard high-heat burn-in cycle to season the racks.

Performance Testing

Low-and-slow cooks were logged with the built-in meat probe cross-checked against a separate calibrated thermometer, alongside external probes at multiple rack heights to map consistency top to bottom.

Reliability Testing

An overnight pork shoulder smoke, a windy-condition heat retention check, and a cold-start test rounded out our testing, along with a dedicated check of the built-in probe's accuracy against our reference thermometer.

Key Features In-Depth

Temperature Consistency

The Tightest Control We've Measured

The digital controller with built-in meat probe held our target 225°F within 8-10°F across every test cook — tighter than any gas, charcoal, or pellet smoker we've reviewed. The insulated double-wall body clearly contributes here, resisting the temperature drift we've measured on thinner-walled gas and charcoal designs during our windy-condition test.

The Built-In Meat Probe

Having a meat probe integrated directly into the controller, rather than requiring a separate purchase, meant we could monitor internal food temperature without opening the door at all. Our accuracy check against a calibrated reference thermometer showed the built-in probe reading within 2-3°F, accurate enough to trust for doneness without a backup.

Four-Rack Cooking Capacity

The four chrome-coated racks comfortably held two full pork shoulders plus two racks of ribs during our capacity test, with even heat distribution across all four levels — a genuinely large capacity for a smoker in this price range.

Smoke Flavor Tradeoffs

Milder Than Fire-Based Smokers

The side-loading wood chip tray produced real, measurable smoke — our chicken thighs and pork shoulder both developed a visible smoke ring during testing — but flavor intensity was the mildest of any smoker we've reviewed, since there's no live combustion generating heat, only the chip tray smoldering from the electric element's residual heat.

Chip Loading Without Losing Heat

The side-loading door for the wood chip tray was a genuine convenience, letting us add chips mid-cook without opening the main door and losing the accumulated heat — a design advantage over smokers where the chip source shares the same access point as the food chamber.

Masterbuilt 40-Inch Electric Smoker vs. Competitors

vs. Weber Smokey Mountain 18-Inch: We've tested the Smokey Mountain in depth, and it delivers significantly stronger, more authentic smoke flavor from live charcoal combustion. The Masterbuilt counters with dramatically easier operation and the tightest temperature consistency we've measured — a real tradeoff between flavor intensity and hands-off convenience.

vs. Pit Boss 3-Series Vertical Gas Smoker: We've tested the Pit Boss 3-Series in depth as well, and it offers slightly more cooking area at a similar price with a faster warm-up time. The Masterbuilt's advantage is not needing a propane tank at all, plus a built-in meat probe the Pit Boss doesn't include standard.

Who Should Buy the Masterbuilt 40-Inch Digital Electric Smoker?

Buy it if you are:

• New to smoking and want the absolute lowest-effort startup — no fire, no fuel tank, just plug in and set a dial
• Living somewhere with open-flame restrictions, such as some apartment or condo balconies, where electric may be the only permitted option
• Prioritizing temperature consistency above maximum smoke intensity
• Wanting a built-in meat probe without buying one separately

Look elsewhere if you are:

• Prioritizing maximum smoke flavor — a charcoal or offset smoker delivers noticeably stronger, more authentic results
• Not near a reliable power outlet where you plan to smoke regularly
• Also wanting searing capability on the same unit — no electric smoker offers this, so pair with a separate grill
• Wanting the strongest possible flavor-to-price ratio — charcoal generally wins here despite the added fire management

Setup and Care

Assembly: The Masterbuilt ships nearly fully assembled. Attaching the racks and legs took our tester 40 minutes solo with a screwdriver, among the fastest of any smoker we've reviewed.

Power: Requires a standard 120V outlet; no propane tank or charcoal purchase needed. Confirm your outdoor outlet or extension cord setup can reach your intended smoking spot before buying.

Wood chips: Load the side-mounted chip tray with dry wood chips; expect to refill periodically during longer cooks, checking through the viewing window rather than opening the main door when possible.

Cleaning: Wipe down the interior and racks after cooling, and empty the drip pan regularly to prevent grease buildup. The insulated body cleans easily since there's no ash or charcoal residue to manage.

Cover: A fitted cover is strongly recommended, since the digital control panel is more weather-exposed than the mechanical dials on gas or charcoal smokers.

Frequently Asked Questions

Is the Masterbuilt 40-Inch Digital Electric Smoker worth it at $349–$399?

Yes, for beginners or anyone who wants the lowest-effort smoking experience possible. It delivered the tightest temperature consistency we've measured on any smoker — just know smoke flavor is milder than a charcoal or gas option.

How does an electric smoker compare to a charcoal smoker for flavor?

Our testing found the Masterbuilt produces real, measurable smoke via its wood chip tray, but the mildest flavor of any smoker we've reviewed, since there's no live combustion. If maximum smoke intensity matters most, a charcoal smoker delivers noticeably stronger results.

Does the Masterbuilt 40-Inch have a meat probe included?

Yes, a meat probe is built directly into the digital controller. Our accuracy check against a calibrated reference thermometer found it reading within 2-3°F, accurate enough to trust without a backup probe.

Can I use an electric smoker on an apartment balcony?

Often, yes — many apartment and condo policies that restrict open-flame charcoal or propane grilling still permit electric smokers, since there's no flame or combustion involved. Always confirm your specific lease terms and local fire code first.

How much cooking area does the Masterbuilt 40-Inch have?

975 sq in total across four chrome-coated racks, comfortably fitting two full pork shoulders plus two racks of ribs simultaneously in our testing — a genuinely large capacity for a smoker in this price range.
