Rustic Mushroom Soup
Winters back home in Venlo were cold in a way that made you shiver through your socks and scarves. And in those long, gray months, soup was a ritual. Mostly broccoli soup for me and mostly, I did not want to eat mushrooms. Somehow I just didn’t like them.
That changed one evening in France, when I was 11 or 12. My father was sick (a silly story involving vanilla ice cream on the street) and my mother had a restaurant reservation that couldn’t be canceled.
I was meant to be left behind in the room with room service fries, perfectly happy. But the universe had other plans: I went to the restaurant and ended up eating an entire mushroom menu with my mother. I don’t remember the restaurant’s name, but I remember the moment clearly. Something clicked. Mushrooms suddenly weren’t scary. Mushrooms could be delicious. Mushrooms could be magical.
From that day on, I never shied away from them again. And it’s a lesson that has stayed with me through travels to Korea, China, and beyond, where mushrooms were everywhere on the menu.
This mushroom soup is a tribute to those memories. It’s rustic, cozy, and deeply flavorful, but it’s also simple, made from ingredients you probably already have in your pantry. Toasting the mushrooms in batches builds rich, deep umami and color. A Parmigiano Reggiano rind adds natural richness without cream. Soy sauce gives a subtle savory depth. Fresh herbs and a few reserved mushroom pieces remind everyone at the table that this is real mushroom soup, not just a creamy beige liquid.
Serve it with a swirl of crème fraîche if you like, or just enjoy it as it is, warm, earthy, and unapologetically mushroomy. This is soup that feeds both body and memory.
