The Chicken Fat Bolete, a funky looking, relatively unloved mushroom. The best part about picking these is that every year I inevitably have to try and beat the Eastern European population of the Twin Cities to the spots where these grow in order to get them first. Essentially, these are a type of slippery jack mushroom, which means they’re a bolete (a mushroom that has pores instead of gills). They differ from other boletes in that their cap can be slimy, yep, slimy when it’s moist outside. The slimy-ness is less apparent when It’s dry, and they become a bit tacky to the touch.
What I find special about Slippery jacks is that they’re are beloved by people from Eastern Europe, contrastingly, most American hunters I know don’t care for slippery jacks at all and regard them as a garbage mushroom. Cultural preferences with food are interesting things, and believe me, it’s a thing.
Habitat
I see chicken fat boletes in Minnesota and the surrounding region almost exclusively with white pine. They hide in the long grass under the pines and it seems to me they like trees younger although I do see them occasionally with older pines too. They’ll start to fruit typically in August, at the end of the Bolete and Chanterelle season, but before the Honey Mushrooms. They grow in troops, sometimes I will randomly come across twenty or thirty mushrooms in a nice pocket while not even looking for them.
Cooking
I will be upfront and say I don’t cook these fresh, they are not that great. Fried up in garlic butter, cooked with wine and herbs, stewed in meat stock, whatever I do the result is the same, they’re just a bit bland compared to other mushrooms. Once dried though, they have a rich woodsy flavor that makes a great addition to mushroom mixes, and let be clear: I prefer these in mixes of dried mushrooms.
Their flavor is very rich, as in it’s an acquired taste. Do you like things like liver pate or organ meats? If so you may really like these. For the culinary faint of heart though, these have an aggressive, almost organy flavor, so I like to mix them with other boletes like leccinums, porcini, or other boletes to make a blend.
Preservation
If you have a dehydrator, slice the mushrooms thinly, discarding the stems, and then place them in the dehydrator. If your dehydrator has metal drying racks, you’ll want to spray them with some nonstick spray, since these guys have a tendency to stick (alternately place the thinly sliced mushrooms on parchment) then dry on the lowest setting of your dehydrator.
You’ll want to do this immediately the day you pick them, otherwise they will turn to a pile of slime in your fridge, bolete mushrooms have a horrible shelf life, although these are better than porcini. A word of advice too on de-hydrating, since mushrooms are very delicate things, make sure the de-hydrator isn’t too warm. If you can feel warmth coming off of the fan, open the door a little to let in some cooler air. Too much heat while dehydrating can spoil your whole batch.
If you do not have a dehydrator, lay the thinly sliced mushrooms out on a cookie sheet covered with wax paper and blow a fan over them, making sure that none of the mushrooms are touching, just a little bit of excess moisture can cause these guys to go bad. A couple days later when they’re cracker dry, store them in a sealed container like a glass mason jar, they will keep for a very long time.
When you want to re-hydrate chicken fat boletes to use, remember to pick out the little blades of grass that will stick to their cap, soaking in water will release these, and they will float to the surface of whatever liquid you are re-hydrating them in. Simply pick the grass out, then pick out the mushrooms, strain the liquid, and then combine the liquid and the reserved mushrooms to add to whatever dish you’re creating.

My Polish grandmother and mother always reminded me that with Suillus (maslaki) you must always remove the thin slimy membrane that covers the cap to avoid indigestion. Have you heard anything like that?
Hi Chris, yes I have definitely heard and felt the indigestion that is possible from slippery jacks. It is ONLY from ingesting them fresh from my experience, and was quite mild. This, and their very short shelf life is why I dry all slippery jacks immediately to preserve them. Slippery jacks are among the most under represented mushrooms in my opinion, but people like your grandmother know they are special. With the chicken fat bolete in particular, peeling the cap would not be possible, since they are so small. Other slippery jacks and similar mushrooms I like to peel though, such as leather veiled boletes.
A question about dehydrating these. I have a decidedly low tech cabin that has tons of these growing in the surrounding woods. I don’t generally bother with them because, until your article, I have not found the descriptions of them as an edible compelling. Anyway, I would like to dry them partially at the cabin and then bring them back to finish off in the dehydrator I have in my city home. Any thoughts or advice?
I would cut them into thin slices and and place them on screens or something that allows air to circulate around them. It will help a lot if you have a fan of some sort or a breeze. Stringing them up on a line after they’re sliced would be time consuming, but would also work.
White Pine Boletes are not Slippery Jacks IMO. I’ve dried a lot of mushrooms at my hunt camp with an old window screen suspended over the wood stove
They may not be exactly the same as other slippery jacks, but for culinary purposes(the subject of this website) their flavor is very similar, that’s why I refer to them as such.
My Father strung Suillus by string, with stems, hours of work, total failure…in the 60’s. Never forayed them again. Now, Imold.. stayed away because of always peeling cap skin from literature. Now, no stem.. slice …dehydrate..sounds easy. I will try. Thanks. Suggust any fantastico Bolete guide books with Amazing color pictures Bessette’s which I will order?

Bessette’s North American boletes is as good as you will get. Chicken fat boletes will dry like a dream in a dehydrator.
I just sauteed a batch in plain oil side by side with blueing bolete and honestly… the suillus americanus has a lot more kick to it than blueing. Yough specimen have a nice texture. They have a nice tang and a nice citrus flavor that lasts, I would definetly serve them fresh and cooked with fish, wild rice or mixted with lobster mushroom! But it’s true that their flavor might be a bit off to people who seeks a more general bolete flavor.
Their flavor is a bit stronger, but I don’t mind them especially if they’re prepared in a blend. They get a very rich after drying too. Good for you for doing some taste testing, there are so many differences between species that’s worth comparing and contrasting.
Hi Alan,
Just found your site…Great Post!!!
However…!!!…you are giving away some great secrets!!!…ha, ha.
Suillus are one of the unsung heros of the mushroom world, and this post reflects that. They are simply a delicious mushroom if one has been taught (or learned) how to prepare and use them. Of those of use raised Wild Harvesting this is one of the…go to…mushrooms as they are so plentiful in their season…and most do (or have) passed these over as…not good to eat. The enzymes in fresh specimens can cause severe indigestion in many folks, but I also find that the…modern stomach…a very weak and sensitive thing in most Westerners. The edible members of this Genus I find strengthens digestion if one has built up their pallet and system to Wild Foods and a much more robust Paleo Diet. I offer that as encouragement, yet also a warning that Wild Foods are something to move slow with in adding to a diet not use to them…
Regards,

Hi J, and you’re totally right. My friends from Russia and Eastern Europe especially love all species of Suillus. From my experience, most people in America have been conditioned to like other more well known mushrooms, which means more Suillus for you. How do you like to eat them?
Do you cut up all of the mushroom, stem included, or just the cap when drying out? I’ve got a ton of her growing in my yard under white pines through out the year excluding winter. I’d like to dry some right now so I can try your recipe in a few days. We always have an abundance of it and a new batch is up now that I don’t want to waste.
Cut it all up.
Time is of the essence!
I usually pick white pine boletes in the autumn here along the Ottawa River but not many. I just found enough to fill a 5l pail and will dry them. We have a GE convection oven which keeps quite warm with the door agar slightly and the light on. Of course the there will be no convection so I will substitute an old computer fan.
I am new to mushrooming I live in Michigan and found these growing in my back yard I have never picked any wild mushrooms nor do I have a dehydrator so how would you recommend me taking care of these babies I guess cut them all up in smaller pieces and lay them out in front of a fan ids my best bet please give me all the tips to make these mushrooms I am so excited to try this
Find a way to dehydrate them, set them in a low oven, etc.
Please give me tips as I am new to this hobby I found a ton of these growing in my yard I have no dehydrator
can you list the edible mushrooms that are found on ash trees should there be any if you knowledgeable of
Refer to Boletinellus merulioides.
