Japanese Mashed Potatoes with Mushroom Gravy

There’s no cream, oil or butter in these easy mashed potatoes. There, I said it!

“There’s no way these easy mashed potatoes can be good without any fat or cream in there. Aren’t they going to be dry?” is what my husband was thinking when I told him I had made healthy easy mashed potatoes.

I can see his point and I have to admit that these easy mashed potatoes are definitely more fluffy than creamy, but once you pour the shiitake mushroom gravy on top, you won’t miss any of the buttery goodness you’re used to having. Is this the best mushroom gravy ever?

My hubby thinks so and I’m not too far behind him on that statement. Yes, this shiitake mushroom gravy is crazy good!


The consistency of the gravy is just like that of good old Chinese food – thick, gooey and sticky (like in mapo tofu).

The mix of button mushrooms and shiitake mushrooms bumps up the umami factor by ten folds and gives the gravy plenty of earthiness and depth of flavor. I’m sure it’s good with a steamy bowl of rice but I’m crazy for easy mashed potatoes and gravy, and these two together make such a comforting winter side dish, don’t you think?

Beside, a recent research done at Mc Gill University shows that potatoes are actually good for us and can help prevent weight gain. To this I say “bring on the potatoes”, that’s wonderful news!


I always get excited when I am faced with the challenge of making something healthy and tasty using a dish that traditionally isn’t. I’ll flip through cookbooks to get the wheels turning and pick a few options I think would be fun to mess with.

I put on my favorite Netflix tv show or iTunes radio channel and get lost in my pots and pans.

It’s heaven for a home cook like me, a fun Saturday afternoon while my cat is asleep on the window ledge and my husband busy killing zombies on the PS3 – It’s the simple, happy life.

easy mashed potatoes

I usually serve mashed potatoes on special occasions like Christmas and Thanksgiving because I use lots of butter and other ‘thigh thickening’ ingredients. Anything with lots of fat and calories I save for holidays and birthdays! But now that I know how good low fat (I’m using 2% milk) mashed potatoes can be, easy mashed potatoes will definitely be appearing more often on my menu.

The day I shot this dish I served these easy mashed potatoes with lean beef burgers (topped with plenty of veggies) and a green salad. Nom nom nom…
