Fancy up regular mashed potatoes with a layer of mushroom duxelle—a sauté of finely chopped mushrooms and shallots. We omitted the traditional butter in the duxelle and added chard for a nutritional boost. Serve this hearty side in place of mashed potatoes at any holiday feast or enjoy it as a vegetarian main dish.

"Made this last year for Thanksgiving and it's been requested for THIS year's holiday table. I'm going to add Swiss Chard to the spinach and a wider variety of mushrooms this year. With 2 vegetarians at the table, this will be a hit again...

Having my son's vegetarian girlfriend for Thanksgiving made me try a bit harder on side dishes and this one was truly a find! I expect I will always have it for holidays! The duxelle was fancy and so delicious. My son loves mushrooms and chard, and we all love good food so it was a hit with everyone. I made a portobello gravy from another garlic mashed potatoes recipe.and it was spectacular with it. Good with tofurkey and/or turkey!


this was delish the first nite and not so good every nite after - DRY! the mashed potatoes were like eating a baked potato not fully cooked! other than that, it was good and will probably make again (although a bit time consuming) - i'll just add milk or chicken broth to it so the leftovers aren't so dry!

I will like to ask a question, Could you make the topping with mashed cauliflower instead of potatoes?


I, too, made this for Thanksgiving dinner and will make it again at Easter. It was absolutely delicious. I used spinach, too, but will try blanched kale next time for a nutritional boost. If you love mashed potatoes, Gruyere cheese and mushrooms (and even if you HATE mushrooms, apparently, as one of our Thanksgiving diners told us---but he had 2nds and 3rds!), you cannot go wrong with this recipe.


This was a hit at Thanksgiving for my family! I used spinach because I had it on hand! I also must say it was fantastic as leftovers as well! Great recipe and pretty easy too!


Excellent. I made this for my family and liked it so much made it again the next week.
