Mashed potatoes with truffle oil and porcini mushrooms

This is important, this means something

Roasted garlic and silky truffle oil take mashed potatoes to a whole new level. You may need a bit more cream depending on how you like your potatoes. This serves a large party, but can easily be scaled down. Although who does not like leftover mashed potatoes?

Mashed potatoes

  • 5 pounds russet potatoes, peeled and boiled
  • 5-6 cloves roasted garlic
  • 1/2 cup heavy cream
  • 1 tbsp truffle oil
  • 1 tsp ground porcini powder (about one dried mushroom ground)
  • 1/4 cup butter
  • salt and pepper to taste

To roast garlic, wrap peeled cloves in foil with a bit of olive oil and place in oven at 350 for about 15-20 minutes. Remove from oven and mash with fork. Boil potatoes until tender. Scoop into a large bowl. (A little potato water won’t hurt anyone.) Mash with butter while still hot. Add garlic, oil, porcini powder and cream and mash until incorporated and no longer lumpy. Season with salt and pepper to taste. Serve hot.

    This sounds exquisite! What a wonderful combination of flavors!

  4. nrhatch says:

    Mashed potatoes are one of my favorite comfort foods ~ tonight we had roasted Yukon Gold new potatoes. Also YUM!

  5. BrainRants says:

    Oh my god. I had an embarrassing moment just reading this. … and this after a full schnitzel and red cabbage dinner.

  6. oh wow. this sounds incredible. you had me at the silky truffle oil!

  7. eva626 says:

    i actually never really had a good batch of mashed potatoes! i wonder what it tastes like (the good kinds). ill make my mom use your recipe!

  8. Joanne says:

    Porcini powder? I’ve never seen or heard of such a thing. I’m intrigued! For some reason the smell of truffle oil or salt makes me nauseous. I’ve heard that it’s fairly different from actual truffle though. I wouldn’t know…I’ve never had the opportunity to buy fresh truffle. I want to try it so badly though!

  9. ChgoJohn says:

    This dish looks incredible and sounds delicious, just like we’ve come to expect from you both. And before I forget: Laissez les bon temps roulette!!!

  10. I’ve heard and read nothing but amazing things about using truffle oil. That’s it. I’m splurging and getting a bottle!

  11. MarkG says:

    Like Joanne above I have not come across porcini powder. I do however have a bag of dried porcini that I rehydrate and add to risottos – could these be utilised? Maybe rehydrated, then blended and added to the mashed potatoes?

    You do not specify black or white truffle oil. I tend to find the white oil more pleasant. It is also used more widely in the restaurants I frequent. It is also more expensive!

    It goes very well in roasted butternut squash soup.

  12. This is so mouth watering, I feel like eating some mashed potato now… Mmmm!

  13. Delicious autumnal dish – could be the idea for today’s lunch.

  14. This is the most decadent mashed potato recipe ever!
    🙂 Mandy

  15. Would it be rude for me to not pass the bowl round the table? Yes? Ok, you´ll just have to make extra then 🙂

  16. Oh my….porcini powder and “silky” truffle oil…never heard of either. My pantry is getting full reading your blog.

  17. Natalie says:

    This is one gourmet mash! I could definitely eat the whole bowl with a spoon, don’t think I could share it though!! I made the calzones and they were lovely will be posting the recipe in a few days (when I’ve caught up with myself) and will link back to you, thanks for the inspiration!!

  18. Looks great!
    Happy Birthday Weekend, Katherine!

  19. I’ve never had truffles or truffle oil…I think I need to try them as soon as possible!

  20. Now those are great looking mashed potatoes – and I’m sure they taste amazing!

  21. Judy says:

    I fell in love with porcini mushrooms a few years ago, it was one of the items I was sure to bring back with me when we visited Italy. Just bought some truffle oil last week, haven’t used it before, so I look forward to the adventure. Porcini and truffle oil? Mashed potatoes? What’s not to like?!

  22. nancyc says:

    I love mashed potatoes–this sounds like an awesome recipe!

  23. Chef Scar says:

    Yum! Porcini mushrooms are the best, and truffle oil…the best thing next to real truffles! Putting these together with mashed potatoes sounds like a winner!

  24. TasteFood says:

    This is one dressy potato recipe and I love it.

  25. Lea Ann says:

    Well I love french fries in truffle oil…why not mashed potatoes? Sounds great Greg.

  26. Sissi says:

    You prove that even the most humble, everyday dish can become a luxurious, sophisticated meal. An excellent and creative cook is the only necessary condition.

  27. ceciliag says:

    What an awesome take on mashed potatoes, you are right they will reach a new level! c

  28. Wow! I love regular mashed potatoes and this just takes it to a new level. I’ve been looking at truffle oil every time I walk by it in the store but haven’t taken the plunge yet…

  29. spicegirlfla says:

    It’s not Thanksgiving unless you have the mashed potatoes!! I like the roasted garlic in the mash and truffle oil…oh my, very gourmet!

  30. Kristy says:

    This takes mashed potatoes to a whole new level! I love the addition of ground porcini in the potatoes (of course the garlic too!) and a bit of truffle oil. I’m not usually one to heap the mashed potatoes on my plate at Thanksgiving, but if they were made like this, I sure would!

  31. Hotly Spiced says:

    Mash with truffles! Delicious. That’s an incredible side-dish.

  32. Charles says:

    Mmm, delicious Greg – the complete opposite of some mashed potato I made recently (believe me, I normally make damn fine mash!). I have no idea what the hell was wrong with the potatoes but when mashed they had some sort of weird, porridge, glue like consistency. Totally horrible 😦

  33. I just knew I shouldn’t have dropped in this close to dinner! I’m now famished and craving just a taste… Delicious combination of flavors!

  34. Susan says:

    This is some seriously decadent cooking! Where does one find porcini powder? Or do you just grind dried porcinis?

  35. I love truffle oil! So flavorful. Your mash looks great.

  36. rsmacaalay says:

    This must be the best mashed potatoes I had ever seen, just look at those ingredients porcini and truffle oil, mmmmmmmmmmmmmmm

  37. Eva Taylor says:

    I ran out of Porcini powder about 4 months ago; I’m still on the lookout! I love the flavour combos Greg, must have been INCREDIBLE with the turkey gravy!

  38. I am such a huge fan of Mashed potatoes but I never would’ve come up with the idea of adding truffle oil to them. Delicious

  39. Greg, these potatoes sound luxurious. We would have to arrange for valet parking as well for our dinner guests. Have a great holiday.

  40. I love the idea of the powdered mushrooms!

  41. egg me on says:

    These potatoes are extremely important — and totally mean something! Cream, butter, truffle oil. Yowza. Well done.

  42. You’ve taken mashed potatoes to the next level my friend.

  43. I can’t keep up with you two cooking whirling dervishes! I am so impressed and so jealous since my kitchen is basically a chalk outline right now with plastic and duct tape keeping me out. I guess that was the only way to keep my hands off it at this moment. Your mashed potatoes sound dreamy! I really wish I could be at your house on Thanksgiving and at my family Thanksgiving all at the same time. I think would have died and gone to heaven. 🙂

  44. These look good. It doesn’t make any difference how many potatoes I put into the dish during the holidays, it is never enough. My family members would go into some kind of fit if they were not on the table and they are all afraid I am not going to make enough.

  45. JamieAnne says:

    This sounds very tasty!

  46. Mel says:

    yum! I am going to try to get a bottle of truffle oil soon.

    Am holding my first Thanksgiving dinner ever this year (being un-American…. but I’m learning!) and will be sure to find some ideas on your site 🙂

    Sweet! I just bought a bottle of Truffle Oil, and will probably debut it in this manner–thanks!

  49. that is what I call posh mashed potatoes, delicious.

  50. Ed would hate this! He has a mistrust of all things funghi as he thinks they are ‘shifty’. As a result we never have anything at all mushroomy in the house. Ah how I miss them.
