This creamy, yet dairy-free and vegan roasted mushroom and cauliflower soup is warm, comforting and full of rich, earthy flavor.
If I had to come up with one of my favorite things to eat in winter and all year-round, it would be soup. Creamy and comforting, soups are an especially easy way to get in all those healthy and nourishing vegetables we could all use more of in our diets. Not to mention that they are deliciously warm and soothing any time of year but particularly so in the winter.
This cozy roasted mushroom cauliflower soup is hearty and satisfying while offering lots of rich flavor. Its savory, earthy flavor is warm and inviting on a cold winter day.
Now this isn’t the kind of bland and overly thick mushroom soup you’d find in a can, it’s a cream-less mushroom soup with lots of deep umami flavor thanks to both dried and fresh mushrooms and a velvety texture thanks to cauliflower and cashews.
How to Make Roasted Mushroom Cauliflower Soup:
The secret is a quick roast in a hot oven. Both cauliflower and mushrooms have a high water content. Roasting them first in a hot oven concentrates their flavor and gives them a rich savory note that other cooking methods would not. Both are tossed with some fresh thyme and ground coriander then drizzled with olive oil and popped in the oven to roast for about 20 minutes or until golden and tender.
In the meantime a simple mushroom broth is made by soaking dried mushrooms in water and letting them sit. Dried mushrooms have a wonderfully strong and concentrated flavor that infuses the water creating a full-bodied and earthy broth in about the same amount of time it takes the vegetables to roast.
Next fragrant garlic and chopped leeks are quickly sautéed in a bit of oil until softened to which the roasted vegetables and mushroom broth are added and then simmered together to marry all the flavors. Half the soup is pureed in the blender with a handful of cashews until creamy and smooth then pulsed with the remaining soup for a silky base punctuated throughout with bits of roasted mushrooms and cauliflower.
So creamy without a hint of cream, this roasted mushroom cauliflower soup is a deliciously comforting companion on a cold winter’s day.
