Roasted Butternut Squash and Leek Soup with Sauteed Portobellos

My mom made a really great potato and leek soup the other week while I was home for the holidays. I decided to make my own version, replacing the summer garden’s potatoes with the fall garden’s butternut squash. The results surpassed my expectations, creating a nutty, slightly sweet and velvety soup, perfect for the cold days that are progressively creeping in. The thing I love about pureed veggie soups is that they yield an extra creamy texture without one drop of heavy cream needed. All that cream will only weigh you down, so don’t bother adding it in. The rich flavors of the roasted veggies alone are more than enough to bolster this soup into a hearty dinnertime meal. Top it off with some sauteed portobellos to add a touch of texture and an extra veggie-derived heartiness. The soup is full of vegetables, but also incredibly full of flavor. No meat, no dairy, and no room to miss either. A perfect vegan-friendly fall/winter meal for any styled diet. Try using any leftovers as great dip for cooked broccoli.

Roasted Butternut Squash and Leek Soup with Sauteed Portobellos

(Serves 5)

-1 head garlic, unpeeled
-1 medium-large butternut squash, peeled and sliced into 1/2-inch semi-circles (about 4 cups)
-4 leeks
-2 cups vegetable broth
-2 cups water
-3 Tbsp. olive oil
-Parsley, chopped
-One batch of sauteed mushrooms (see recipe below)

Preheat oven 400F. Lightly grease a large baking sheet lined with aluminum foil. Coat squash with 1 Tbsp. olive oil. Spread out on baking sheet, and sprinkle with salt and pepper. Wrap entire head of garlic in aluminum foil and place next to squash. Slice leeks into 1/3 inch circles and place in strainer. Run through water to clean them, and then pat dry. Line a large rectangular cake pan with aluminum foil and lightly grease. Toss leeks with remaining 2 Tbsp. oil. Place in baking pan and sprinkle with salt and pepper.

Place squash, garlic, and leeks in oven, and bake 45 minutes, or until squash are fork tender, flipping squash and stirring leeks halfway through. Remove from oven.

Place leeks and squash in a large saucepan over medium heat. Cut end of garlic head, and squeeze out roasted cloves into pan with squash. Add water and vegetable broth and bring to a simmer. Cook for 5 minutes. Remove from heat. In batches, place squash mixture into a blender or food processor, pureeing until smooth, and then returning contents to pan. Serve, topping each bowl with mushrooms and chopped parsley.

    Sounds amazing.
    I did a demo yesterday with our in-house vegan chef. We made butternut squash risotto and sauteed kale with fried portobella cutlets. Many of the same ingredients!! It was delicious.

      Yes, I saw that, but what exactly is neuropathy and flushing of the skin? Sorry, should’ve been more specific in asking you my question, but does flushing of the skin just mean redness?

    The soup looks and sounds amazing! Haven’t made portobellos in a while; have to pick some up soon… Thyme sounds great with mushrooms!

    Re: comment
    Neuropathy is any damage to a nerve in the body, which ends up causing a chronic life-threatening condition. Many times people with diabetes get this, and it’s called peripheral neuropathy. This is when they can’t feel their limbs and extremeties. No fun.

    The flushing caused by niacin is caused by the effect of niacin in opening up the blood vessels. It’s not life-threatening, necessarily, but it’s embarrassing and I think it probably itches a lot.
