Creamy Mushroom Soup with Black Rice

For our first entry into the year’s culinary adventures, we’re showcasing mushroom soup. The cold months can prove a challenge to someone looking for fresh, local, and healthy produce, and most varieties of mushroom are available all year round. They’re gorgeous, they’re really good for you, and we’d like to show you how we make them into a warm, creamy, incredibly silky soup that is as tasty as it is beautiful. For a soup this rich, there’s remarkably little dairy involved (and even that much is optional). And the only gluten is in the breadcrumb topping, so that’s easily avoidable as well, making this an easy vegan and gluten free meal.

Mushrooms, done right

Emily was kind of a late bloomer when it comes to mushrooms. It was only a few years ago that she realized that she does, in fact, enjoy them, but only if they’re cooked, and prepared in certain ways. A raw white button mushroom, of the kind you might encounter in a deli salad, has the appearance and flavor of earthy, moldy, damp styrofoam. No bueno. Also mushrooms that have been cooked at a low temperature until they get soggy and slimy aren’t doing themselves any favors, either. But, once you cook a mushroom properly, over high heat, not moving it around too much, magic happens. It becomes beautifully brown, caramelized and develops complexity of flavor and texture. Toss in some fresh herbs, a little wine or sherry and a pat of butter … sheer heaven piled on a slice of toast or tucked inside an omelette.

Now that we have pierced the secret veil of mushroom cooking, we’ve become much more open to trying different varieties, cooked different ways. Here, we use a combination of crimini (sometimes called baby Bellas, or chestnut), and shiitake. If either of those aren’t available or too expensive, you can use whatever variety looks good — even white button mushrooms would be delicious here. For an extra punch of mushroomy richness, we also use dried porcini, which have a deep woodsy flavor. And don’t waste the liquid they reconstitute in, it’s packed with flavor too (though you will want to filter out the sandy silt that collects at the bottom).

The Mushroom Soup Recipe

This recipe is an updated version of a mushroom soup from The Balthazar Cookbook – the best thing about it is that it’s truly packed with mushrooms and ends up thick and creamy once blended. In fact, it’s so luxurious on its own that it doesn’t really need a creamy component added to it, though it does make the soup incredibly silky. Feel free to leave the mascarpone out if you want a vegan soup, or add just a splash of coconut or cashew cream.

We reduced much of the fat from the original recipe and added a plug of sherry (because a bit of booze makes everything yummier). We also partnered it with black rice, a wild variety with a nutty flavor that you should be able to find in your grocery. (Like the mushrooms, it’s super nutritional: unprocessed rice retains a lot of the fiber and nutrition that white rice loses when processed.) You can also use wild rice (which is actually a type of grass), or red rice, which is a little shorter than black rice and has a Rooibos-like scent. Just be aware that different wild rices have very different cooking times, so make sure to follow the instructions on the bag.

Toppings for the Soup

Even a delicious soup needs to be prettied up some, so we topped it with caramelized enoki mushrooms and garlic-butter breadcrumbs. Enokis are a delicate variety of mushroom with tiny heads and long stems joined at the base in clumps. They’re popular in broth bowls, and once sautéed, add that characteristic mushroom shape to the top of the pureed soup. The enokis, combined with the buttery crispy breadcrumbs, add a lovely contrasting crunch to the smooth soup, along with a pretty swirl of mascarpone. Obviously the topping is completely optional (and leaving out the breadcrumbs leaves the soup Gluten Free). We had the leftovers plain, with just some crusty bread on the side and it was still fantastic.

Blending

A quick note on blending this soup: When we started writing Nerds with Knives, we placed much more of an emphasis on the tools and gadgets that we used in the kitchen. (We’re nerds, we love our gadgets.) Over time, we’ve focused more on the food and somewhat less on the tools. That being said, we recently splurged on a Vitamix blender (thank you, Cyber Monday), and absolutely love it. It turns the soup ultra-smooth, with that silky texture that only seems possible in fancy fine-dining restaurants.

But you don’t need an expensive professional blender to make this. We’ve made it plenty of times using our crappy old blender, and several times with a stick blender. It won’t be quite as ridiculously smooth but it will be close, and the flavor will be identical.

Ingredients

• 3/4 cup black rice or any kind of wild rice
• 1 ounce dried mushrooms porcini, morels, or shiitakes
• 1 tablespoon olive oil
• 2 tablespoons unsalted butter or use more olive oil
• 1 pound cremini mushrooms or white button, thinly sliced
• 1 pound shiitake mushrooms stemmed, thinly sliced
• 1 Spanish onion peeled and chopped (about 2 cups)
• Kosher salt and freshly ground black pepper to taste
• 4 garlic cloves peeled and minced
• 2 teaspoons fresh thyme leaves minced
• 4 sage leaves minced
• 1/2 cup dry sherry divided
• 6 cups chicken stock (low sodium), or vegetable stock
• 4 ounces mascarpone (or cream cheese or vegan cream)

For the Enoki Mushroom and Breadcrumb topping:

• 2 tablespoons unsalted butter or extra virgin olive oil, divided
• 2 ounces enoki mushrooms separated into 1-inch pieces
• Kosher salt and ground pepper to taste
• 1 garlic clove grated
• 1/2 loaf 12-inch crusty baguette torn into rough 1/2-inch pieces

Instructions

• Cook the rice according to the package directions. Remove from the heat and set it aside to cool.
• Soak the dried mushrooms in 1 cup of hot water for 20 to 30 minutes, until soft. Strain the soaking liquid through a coffee filter to remove any grit and reserve the liquid, along with the reconstituted mushrooms, until needed.
• Heat the olive oil and butter in a large (5 quart) Dutch oven or heavy soup pot set over a medium-high heat. Add the crimini and shiitake mushrooms. Toss them in the oil and then cover the pot until the mushroom release their liquid, about 5 minutes. Then remove the cover and cook them, uncovered, stirring occasionally, until they turn golden brown and caramelized, about 10 minutes. Add the onion, and season with some salt and pepper. Cook until the onions are soft and translucent, about 7 minutes. Then add the garlic, thyme and sage and cook until the garlic is fragrant, about 1 minute.
• Stir in a 1/4 cup of sherry, all the stock, the dried mushrooms and the filtered soaking water. Bring the liquid to a boil, then turn the heat down to low and simmer for 30 minutes. Add the other 1/4 cup sherry and simmer for 5 minutes longer. Using an immersion blender, puree the soup until completely smooth (or use a standing blender, working in batches and return the pureed soup to the pot). Stir in the mascarpone and the cooked rice.

To make the Enoki Mushroom and Breadcrumb topping:

• Set an 8-inch skillet over medium-high heat and add one tablespoon of butter or oil. When hot, add the mushrooms and let them brown on one side, about 3 minutes. Turn and crisp the other side. Season to taste with salt and pepper and remove to plate. Add the other tablespoon butter and the grated garlic. Stir until the garlic is fragrant, about 30 seconds, and add the breadcrumbs. Toss the bread in the garlic butter and cook, stirring them often, until the bread browns and crisps. Season with a little more salt and pepper.
• Divide the soup into bowls, and top each with some mushrooms and breadcrumbs.
