Building a DIY Smokehouse Shed: From Fresh Timber to Wild Alaskan Salmon Jerky

Today we are looking at an incredibly tasty and highly practical project from the brilliant YouTube channel North To Alaska. If you have ever wanted to combine your passion for custom garden builds with artisan food preparation, this is the perfect source of inspiration for you. In their most recent video, they turned a freshly milled stack of local timber into a fully functional cold smoker shed, and they immediately put it to work making some mouth-watering wild Alaskan salmon jerky.

Building a dedicated outbuilding for smoking meats and cheeses is a dream for many outdoor enthusiasts. It elevates your garden from a simple storage space into a true hub of culinary creation.

Here is a detailed, step-by-step breakdown of how they brought this brilliant little smokehouse to life, along with their fantastic recipe for salmon jerky.

Laying the Foundation and Milling the Timber

Every great outbuilding project begins with a solid foundation. The creators got started by framing out a compact bottom platform measuring approximately 3ft by 4ft. This relatively small footprint is absolutely ideal for a dedicated cold smoker. It keeps the structure manageable for a small corner of the garden while ensuring the smoke remains densely concentrated around the food. At the same time, it provides more than enough internal volume for large batches of food.

To enclose the structure, they utilised their own sawmill to cut fresh 1×10 timber boards. Finding timber wide enough to create this beautiful board and batten siding was a genuine challenge in their local Alaskan area. As they noted, the trees in their region tend to taper quite sharply, making even 8-inch wide boards a bit of a rarity. However, the effort of milling those 10-inch boards paid off immensely. The resulting board and batten siding gives the shed a fantastic, authentic rustic charm.

Interior Design and Adjustable Hanging Racks

Moving to the inside of the smokehouse, the layout was carefully considered to maximise utility. They installed four tiered rows of wooden dowel rods. While these sturdy rods are primarily designed for hanging large, whole salmon fillets directly in the smoke, the spacing was calculated perfectly so that standard flat dehydrator trays could be rested securely on top of them.

Because the wooden racks are screwed into the frame, the internal system is completely modular. They can adjust the heights to accommodate larger cuts of meat, or slide the dowels out entirely. This removability is a massive bonus for hygiene, allowing them to easily power wash the components.

Fire Safety and Protective Flooring Solutions

Cold smoking relies on the slow smouldering of wood pellets or chips rather than an active fire. This means the internal temperature of the smokehouse rarely exceeds 70 to 80 degrees Fahrenheit. Even with these significantly lower temperatures, fire safety is paramount in any enclosed wooden shed.

To prevent the metal pellet smoker tubes from directly transferring heat and burning the wooden floor, they implemented a simple temporary solution by elevating the tubes on small concrete blocks. This creates a safe air gap between the heat source and the timber base. Their long-term plan is to line the bottom of the shed with double-thick concrete boards. This permanent upgrade will create a highly durable, fireproof base where drip trays and smouldering smoker tubes can sit safely without any risk of combustion. Managing the inevitable drips from the smoking meat is also vital for sanitation, so having a heat-resistant floor where removable catch trays can rest is an excellent design choice.

Clever Roofing Details and Natural Ventilation

The roof construction featured a very clever detail that is absolutely essential for anyone planning to build a food-preparation shed. They opted to attach their metal roofing sheets directly to the timber rafters without using any standard roofing underlayment.

While traditional garden sheds always utilise a felt or plastic underlayment to prevent leaks and condensation, introducing thick smoke to modern roofing plastics could cause them to off-gas. This would risk contaminating the carefully prepared meat with a nasty chemical flavour. By keeping the roof construction entirely natural, they ensured their food remained completely pure.

To manage the smoke density and oxygen levels, they installed vented grill louvers on the main front door. This addition allows them to manually adjust the airflow from the outside, ensuring the pellet tubes get just enough oxygen to stay lit and smoulder properly, without letting all that precious flavourful smoke escape too quickly.

The Art of Salmon Jerky: Preparation and Brining

The process began with a few leftover salmon fillets from their previous fishing season. They started by running the fish through a slicer to create perfectly uniform strips. Consistency in slicing is crucial to ensure every piece dries and smokes at the exact same rate.

Next, the salmon was thoroughly coated in a dry brine using a 4:1 ratio of dark brown sugar to canning salt (specifically, 400 grams of sugar and 100 grams of salt). They carefully layered the salmon and the brine in a large container, ensuring every strip was completely submerged. This brining step is essential, as the salt and sugar draw out excess moisture while infusing deep flavour. The fish was then left to cure in the fridge for six hours.

Forming the Pellicle and Cold Smoking

After the six-hour cure, they removed the fish from the brine and thoroughly rinsed off all the surface salt and sugar. After a good rinse, the strips were patted completely dry with towels to remove any lingering surface water.

Before the fish could go into the smokehouse, it needed to develop a pellicle. Smoke simply will not adhere to a wet, glossy surface. To create a tacky, sticky exterior, they laid the salmon strips on their dehydrator trays and ran a fan over them for a couple of hours. This crucial drying phase forms the pellicle, ensuring the wood smoke has something to properly stick to.

Once the salmon felt sticky to the touch, they loaded the trays directly into their brand new shed and fired up the pellet tubes. The salmon bathed in the rich, cold smoke for approximately eight hours. During this time, they checked the pellet tubes, noting that they needed to be refilled after a couple of hours to keep the smoke production going.

Final Dehydration and Tasting the Results

Because cold smoking primarily adds flavour and does not actually cook the meat, the smoked fish was still technically raw and needed a final preservation step. They moved the trays back inside the house and placed them into their kitchen dehydrator. After about five and a half hours of dehydration, the final jerky was perfectly cured and ready to eat.

The final product looked absolutely incredible. After peeling off the skin, which can taste a bit too intensely fishy when concentrated by the dehydration process, they were left with flawless pieces of salmon jerky. In their taste test, they noted that the jerky had a very sweet, subtly smoky, and mildly salty profile. Unlike tough beef jerky that you have to aggressively gnaw on, the flaky nature of the salmon created beautifully tender, bite-sized pieces.

To ensure nothing went to waste, they portioned the jerky out and vacuum-sealed it into small snack packs, perfect for taking on future road trips or fishing adventures. This cleared out their freezer, making plenty of room for this year’s fresh catch of whole fillets, which they are excited to hang from the dowels in their brilliant new smokehouse.

Building a dedicated smoker shed is an exceptional way to elevate your DIY skills, enhance your garden space, and seriously upgrade your outdoor cooking repertoire. If you are a Sheddie who loves preserving food and tackling unique timber projects, a custom smokehouse is an absolute must-try build! It proves that with a little ingenuity and some basic materials, you can create something highly functional and deeply rewarding right in your own back garden. Expanding your horizons beyond standard storage options truly unlocks the full potential of outdoor outbuildings. The possibilities for culinary creativity are endless once you have a dedicated smoking space at your disposal.
