This might be our new crowning achievement. Heaps of veggies (mushrooms, parsnips, squash), tons of aromatics, lentils, and MISO are topped with a whipped, creamy, all-vegan mashed potato and we're pretty confident that this dish is sure to knock your socks off.
In a large heavy bottomed pot over medium-high heat, heat 2 tablespoon oil. Add mushrooms and sear until deeply brown, remove from skillet. Lower heat to medium and add remaining oil. Add onion, celery, parsnips, and butternut squash, cook until starting to become well browned, about 12 minutes.
Preheat oven to 425°. In a large pot, cover potatoes with water and season with salt. Bring to a boil and cook until totally soft, 15 to 18 minutes. Drain and return to pot. Use a potato masher to mash potatoes until smooth.
