Slow Cooker Mushroom and Wild Rice Soup

Making creamy soups in the slow cooker can be tricky because it’s not possible to simmer them with the top off and reduce the liquid. One easy way to thicken without reducing is to use a roux, a mix of flour and butter. Heat the roux in the microwave, then whisk it into the stock in the slow cooker before adding the other ingredients. (If you don’t have a microwave, simply melt the butter in a small saucepan, stir in the flour, let it bubble, then proceed.) This soup is best prepared on the high setting for two reasons: First, when cooked on low, the wild rice becomes too soft before the mushrooms are tender. Second, the roux doesn’t thicken as effectively on low. If you need a longer cook time, omit the rice, put the soup on low for 8 hours, and turn the heat up to high before serving. Cook the rice separately according to package directions, then stir it in before serving. Find a pressure cooker version of this recipe here.
