Buying Guide
Temperature Control for Fish
Fish requires precise temperature management. Cold smoking (below 90°F) imparts a silky texture, while hot smoking (above 180°F) cooks the fish through. The Masterbuilt Slow and Cold Smoker Accessory excels at maintaining low temperatures for cold smoking, making it ideal for salmon and trout. The Masterbuilt 40-inch Digital Electric Smoker offers digital controls up to 275°F, giving you flexibility for both hot and cold smoking methods.
If you prioritize cold smoking, the accessory is a dedicated solution. For versatility, the full electric smoker handles both styles with ease. Consider your typical fish recipes before deciding.
Smoke Generation and Consistency
Continuous smoke is critical for fish. The Slow and Cold Smoker Accessory features a continuous wood feed system that provides up to six hours of smoke without reloading, ensuring a steady flavor. The 40-inch model uses a patented side wood chip loader that lets you add chips without opening the door, preserving smoke inside the chamber.
Both products deliver reliable smoke, but the accessory is specifically engineered for cold smoking where consistent low smoke is paramount. For those who want a complete setup, the electric smoker offers convenience with digital timing. Learn more about affordable options in our best budget smokers for 2026.
Capacity and Space
Consider how much fish you plan to smoke at once. The Slow and Cold Smoker Accessory fits inside an existing Masterbuilt vertical smoker, adding a dedicated cold smoking chamber. The 40-inch Digital Electric Smoker offers 970 square inches of cooking space across four chrome-coated racks, enough for multiple fish fillets or whole fish.
If you frequently smoke large batches, the electric smoker’s spacious vertical design is a clear advantage. For occasional cold smoking, the accessory is a compact addition. Check out the best smoker on amazon for alternatives.
Ease of Use and Cleanup
Both Masterbuilt products prioritize convenience. The Slow and Cold Smoker Accessory heats wood chips automatically with a push of a button and includes a removable ash tray for easy cleanup. The 40-inch model features a removable water bowl and rear grease tray, plus an adjustable air damper for smoke control.
These thoughtful designs reduce the hassle of smoking fish. The accessory is simpler for cold smoking, while the electric smoker’s digital controls make temperature management effortless. For a deeper dive into electric smokers, read our masterbuilt 30-inch digital electric smoker review.

Both products represent excellent choices depending on your setup and needs.
Frequently Asked Questions
Can you cold smoke fish with an electric smoker?
Yes, many electric smokers can cold smoke fish if they have a separate cold smoke attachment or a temperature control that goes low enough. The Masterbuilt Slow and Cold Smoker Accessory is specifically designed for this purpose, while the 40-inch Digital Electric Smoker can also be used for cold smoking with careful temperature management.
What is the best wood for smoking fish?
Mild woods like alder, apple, or cherry are excellent for fish because they complement rather than overpower the delicate flavor. Alder is a classic choice for salmon. Experiment with different chips to find your preferred profile.
How long does it take to smoke fish in a Masterbuilt smoker?
Smoking times vary by method. Cold smoking fish can take 6 to 12 hours depending on thickness and desired texture. Hot smoking typically takes 1 to 3 hours at 225°F to 250°F. Always use a food thermometer to ensure the fish reaches a safe internal temperature.
Do I need a separate cold smoker accessory for fish?
Not necessarily. Some electric smokers can achieve low temperatures without an accessory, but a dedicated cold smoker attachment like the Masterbuilt Slow and Cold Smoker Accessory provides better temperature control and continuous smoke for superior results. If you plan to cold smoke frequently, it is a worthwhile investment. For budget-conscious shoppers, see our best smoker for the money.
