Truffle oil in Stardew Valley comes from putting one Truffle into an Oil Maker, which turns it into Truffle Oil in 6 in-game hours. It sells for 1,065g, or 1,491g with the Artisan profession. Truffles come from adult pigs, and the Oil Maker is a crafting recipe you learn at Farming level 8.
The facts here are from the Stardew Valley Wiki for version 1.6. The real decision most players face isn’t how to make it, it’s whether turning truffles into oil is worth it, and that depends on two professions.
How to make truffle oil in Stardew
- Reach Farming level 8 to get the Oil Maker recipe, per the Oil Maker page.
- Craft an Oil Maker from 50 Slime, 20 Hardwood and 1 Gold Bar.
- Get truffles. Buy pigs from Marnie (16,000g each, and they need a Deluxe Barn) and let them outside once grown.
- Put one truffle into the Oil Maker. Any quality works and the result is the same.
- Collect the Truffle Oil 360 minutes later.
Slime is usually the slowest ingredient to collect. The Oil Maker also turns corn, sunflowers and sunflower seeds into ordinary Oil, though that only sells for 100g.
Getting truffles from pigs
Pigs are where truffles come from. According to the wiki’s Pig page, a fed pig becomes an adult after 10 nights and then digs up truffles outside every day, as long as it isn’t winter, it isn’t raining and there’s open ground for the truffle to appear on. A happy pig at max friendship averages about 3 truffles a day.
Two Foraging professions matter here even though truffles come from animals:
- Gatherer (Foraging level 5) gives a 20% chance of a double truffle.
- Botanist (Foraging level 10) makes every truffle iridium quality.
Rancher doesn’t boost truffles, because the game doesn’t count them as animal products. Collect them daily, too: the Truffle page notes ungathered truffles vanish the morning after day 28 of a season.
Truffle oil or raw truffles: which sells for more?
Make oil unless you have Botanist without Artisan. Truffle oil has no quality, so an iridium truffle and a normal truffle both make the same 1,065g oil. Here’s the comparison from the Truffle and Truffle Oil wiki pages:
| Your professions | Sell the truffle | Sell the oil | Better choice |
|---|---|---|---|
| Neither Botanist nor Artisan | 625g (base) up to 937g (gold) | 1,065g | Oil |
| Botanist only | 1,250g (iridium) | 1,065g | Sell truffles |
| Artisan only | 625g to 937g | 1,491g | Oil, by a lot |
| Botanist and Artisan | 1,250g | 1,491g | Oil, if you have the machines |
Artisan sits on the Tiller branch of Farming at level 10, and boosts artisan goods by 40%, per the wiki’s Skills page. Its description says plain Oil doesn’t benefit, but Truffle Oil does. If you picked Rancher instead, you can swap at the Statue of Uncertainty in the Sewers for 10,000g.
What Stardew players argue about with truffle oil
“Does truffle quality change the oil?”
No, and a Steam Community thread from 2022 worked through why that matters. The first reply put it simply: “Oil has no quality variation.” Several players pointed out the knock-on effect: with iridium truffles from Botanist, raw truffles beat oil unless you also have Artisan. One reply called the Artisan advantage real but small enough that it “might not be worth the trouble.” The wiki confirms the same price gap shown in the table above.
“Botanist or Artisan for a truffle farm?”
A 2024 Steam discussion asked this directly. The answer: both are good, and the gap (1,250g iridium truffle against 1,491g Artisan oil) only becomes meaningful at scale. Someone running a couple of pigs could just sell truffles straight from the shipping bin, while a barn full of pigs makes Oil Makers worth building. The same thread pointed out that most players take Artisan anyway for wine from kegs, so truffle oil comes along for free. One more tip from that reply: build at least one Oil Maker even if you never use it, because crafting one counts toward the crafting achievement for perfection.
Other ways to get truffle oil
Pigs aren’t the only source. The Truffle Oil page lists:
- The Traveling Cart, which sometimes has it in its rotating stock.
- Marnie’s shop at the Desert Festival, for 50 Calico Eggs (added in 1.6).
- Truffle Crabs, which can drop it. Pigs rarely dig one up instead of a truffle, a 0.2% chance per the Pig page.
That’s handy when you need one for a bundle or quest before you own pigs.
What truffle oil is used for
Besides selling it, truffle oil has a handful of uses:
- Community Center: one option for the Artisan Bundle in the Pantry.
- Rain Totem: crafted from 1 Hardwood, 1 Truffle Oil and 5 Pine Tar, learned at Foraging level 9. It raises the chance of rain the next day.
- Mayor Lewis’s quest: on Summer 21 of Year 2 he mails a request for truffle oil. Filling it pays 750g and a friendship heart, and he sends the letter whether or not you own pigs.
- Gifts: Harvey loves it, and most of the town likes it. Skip Jas, Sebastian and Vincent, who hate it.
- Tailoring: spin it in the Sewing Machine for the Dark Bandana Shirt, or use it as a yellow dye at the dye pots in Emily and Haley’s house.
Eaten, it restores 38 Energy and 17 Health, but at 1,000g-plus it’s an expensive snack.
