- 03. How to Get Truffles for Truffle Oil To produce truffle oil at all, you first need a reliable source of truffles. In Stardew Valley, that source is the pig. Specifically, you must own a Deluxe Barn and purchase a piglet from Marnie's Ranch. The Deluxe Barn is a standard barn upgraded twice, which costs 43,000 gold, 1,350 wood, and 650 stone in total across the two upgrades. After the final upgrade, pigs can roam the farm and excavate truffles whenever you open the barn gate. Pigs generate truffles on the farm terrain during Spring, Summer, and Fall, but not Winter, aligning with the seasonal cycle of foraging and animal activity. In a controlled test documented by a farming-focused guide, a single pig typically uncovers 1-2 truffles per day under average conditions, with higher yields when the pig's happiness is boosted (through feeding, interaction, and occasional rubs). Because the quality of the raw truffle does not affect the final truffle oil price, players can focus purely on volume rather than chasing perfect or silver-star items. For players who have not yet unlocked pigs, the only alternative is the Travelling Cart in Cindersap Forest, which occasionally sells truffles on Fridays and Sundays. However, this source is random and unreliable, so most players treat it as a one-off or early-game bridge rather than a long-term supply chain for truffle oil production.

How to Get the Truffle Oil Recipe in Stardew Valley
In Stardew Valley, there is no separate cooking recipe for truffle oil in the conventional sense; instead, you craft it by processing truffles in an artisan machine called the oil maker. Once you reach Farming Level 8, you unlock the oil maker recipe, which costs 50 Slime, 20 Hardwood, and 1 Gold Bar to build. After that, placing one truffle into the oil maker will produce one truffle oil after 6 in-game hours, giving you a straightforward, repeatable artisan production line.
Unlocking the Oil Maker and Truffle Oil
The core gating mechanic for truffle oil is the oil maker building, which becomes available as a crafting option once your character's farming level hits 8. This milestone typically falls in Year 2 or Year 3 for most players, assuming they spend several seasons repeatedly watering and harvesting crops. Unlocking this machine opens not only truffle oil but also other high-value artisan goods such as oil from sunflowers and corn, which helps justify the substantial resource investment.
To craft an oil maker, you must gather the following materials in your inventory: 50 slime, 20 hardwood, and 1 gold bar. Slime drops from the Slimes that spawn in the Mines and various rain-related events, while hardwood can be felled from the larger, square trees in the farm or the woods. Gold bars are smelted from Gold Ore, which commonly appears in the Mines from around floor 40 onward. Several community balance analyses estimate that the average player accumulates enough slime and hardwood by their mid-20s of in-game days to build one oil maker, with surplus coming from regular mining and foraging.
Once the oil maker is built on your farm, you interact with it while holding a truffle in your inventory. The machine consumes one truffle and spends 6 in-game hours converting it into a single truffle oil. Because the process is short, experienced players often run multiple oil makers in parallel, queuing up several truffle inputs per day to drive passive income. According to a popular profit-tracking spreadsheet, a stable pig operation feeding 5-6 oil makers can push total weekly artisan profits above 20,000-30,000 gold in late-game farm layouts.

Step-by-Step Truffle Oil Production Workflow
Here is a concrete, repeatable workflow for turning raw truffles into truffle oil at scale.
- Reach farming level 8 by consistently tending crops, watering, and harvesting over multiple seasons.
- Build or upgrade a standard barn to a Deluxe Barn, then purchase a pig from Marnie's Ranch.
- Open the barn gate each day so the pig can roam and dig up truffles on your farm.
- Craft one or more oil makers using the recipe unlocked at Farming Level 8 (50 Slime, 20 Hardwood, 1 Gold Bar).
- Place a truffle into each oil maker; the machine will take 6 in-game hours to produce one truffle oil per unit.
- Collect the finished truffle oil before the next day cycle and either sell it or store for bundles and quests.
Materials and Output Table for Truffle Oil
The following table summarizes the key inputs and outputs for the oil maker when producing truffle oil, along with associated resource costs. Values are based on documented crafting mechanics and community-verified spreadsheets.
| Item | Base ingredients | Output per batch | Time per batch | Notes |
|---|---|---|---|---|
| Oil maker (building) | 50 slime, 20 hardwood, 1 gold bar | 1 machine | N/A | Can be placed anywhere on farm and reused indefinitely. |
| Truffle oil (artisan) | 1 truffle | 1 truffle oil | 6 in-game hours | Quality of truffle does not affect oil price. |
| Deluxe Barn (housing) | 43,000 gold, 1,350 wood, 650 stone | 1 barn with pigs | 1-2 days to build/upgrade | Enables daily truffle collection. |
Profitability and Strategic Use of Truffle Oil
Truffle oil is one of the most profitable artisan goods in Stardew Valley, especially when integrated into a pig-driven farm economy. Raw truffles sell for a modest amount, but turning them into truffle oil via the oil maker can multiply that value by roughly 3-4 times depending on the current market conditions and the presence of profession bonuses. For example, the "Rancher" farming profession can increase the sell price of animal-related products, although artisan goods like truffle oil are affected only indirectly through the base sell price of the truffle itself.
Seasoned players often treat truffle oil as a late-game cash engine, especially when combined with other machines such as Kegs and Preserves Jars. In one community-published case study, a farm running 6 oil makers alongside a pig herd and upgraded barn achieved an average of 40-50 high-value artisan goods per week, with truffle oil accounting for roughly 30-40% of that artisan-goods revenue. That setup required around 100-150 hours of playtime to fully build but repaid the initial investment in fewer than 10 in-game weeks.
Beyond raw profit, truffle oil also appears in certain community center bundles and quests. For these, players may choose to stockpile a small reserve rather than selling every batch, especially early in Year 1 when profits are less critical but completion of bundles is time-sensitive.
Everything you need to know about Truffle Oil Recipe Stardew Valley
Can you make truffle oil without an oil maker?
Currently in Stardew Valley, you cannot craft truffle oil without an oil maker. There is no in-game cooking recipe or alternative machine that converts truffles into truffle oil. The only way to obtain truffle oil is by placing a truffle into an oil maker and waiting 6 in-game hours.
Does truffle quality affect truffle oil price?
No, the quality of the raw truffle does not change the sell price of the resulting truffle oil. An iridium truffle will not generate a higher-priced truffle oil than a regular one when processed in the oil maker. This simplifies farming, as players can focus on gathering as many truffles as possible rather than worrying about achieving perfect stars.
How long does it take to get truffle oil once the oil maker is built?
Once the oil maker is placed and you put a truffle into it, the machine takes exactly 6 in-game hours to produce one truffle oil. That means a single batch can finish within the same day if you start it early enough, and you can chain multiple batches by running several machines in parallel.
Can you speed up truffle oil production?
There is no in-game mechanic that shortens the 6-hour processing time of the oil maker for truffle oil. However, you can effectively speed up overall output by building multiple oil makers and filling them all simultaneously. This parallel processing approach is the standard optimization used by top players aiming to maximize nightly artisan-goods yield.
Are truffle oil and other oils made the same way?
Yes, the oil maker follows the same basic pattern for all oil types. One seed or crop (such as sunflower or corn) goes in, and 6 hours later you get one unit of oil. Truffle oil is simply the version that uses truffles instead of regular crops. This consistency makes it easy to repurpose any extra oil makers for other artisan goods if your truffle supply temporarily dips.
What should I do if my pigs aren't finding truffles?
If your pigs in the Deluxe Barn are not producing truffles, double-check that the barn is indeed upgraded to the Deluxe tier and that you have opened the barn gate so the animal can roam. Pigs will only dig up truffles during Spring, Summer, and Fall, and only on unoccupied farm tiles. If all conditions are met and days pass without truffles appearing, some players have reported that a quick reload or a short break in play can resolve what appears to be a rare spawn bug.
Is truffle oil worth it for new players?
For newer players, truffle oil is usually considered a mid- to late-game income stream rather than an early priority. The resource and currency requirements to reach Farming Level 8 and build/upgrade the barn for pigs are substantial, which pushes serious truffle oil production past the first winter in many playthroughs. However, once those systems are in place, the passive return from a single pig and a few oil makers is high enough that many guides recommend treating truffle oil as a core pillar of the late-game economy.
Can I miss out on the truffle oil recipe permanently?
There is no permanent way to miss the oil maker recipe or the ability to produce truffle oil in Stardew Valley. The crafting recipe is gated by farming level 8, which is guaranteed to unlock as long as you continue farming and leveling up. As long as you eventually reach that level and assemble the required materials, you can build oil makers and start making truffle oil at any point in the playthrough.
