My friend Heather sent me this recipe. She and all her friends were swooning over how delicious this soup is.

I must admit when I was assembling it, I had my doubts.  Mushrooms and leeks simmering in a stock base looks pretty much like I was brewing a witches brew brought in from the garden. WARNING: This soup does not look visually appealing while being assembled on the stove.

But what this soup lacks in color makes up for in the deepest and richest of flavors.

This Creamy Thyme Mushroom Soup has cast a spell on me — it’s now my all time favorite soup.

Creamy Thyme Mushroom Soup

4 tablespoons unsalted butter
2 Leeks, white and light green parts only, halved lengthwise and thinly sliced
1 large yellow onion
(I added 2 garlic cloves)
3-4 large Portobello mushrooms or 1 lb , brushed clean and chopped
3 tablespoons all-purpose flour
6 cups chicken or veggie stock (I used Better than Bouillon Organic Mushroom Base)
1.5 tablespoons fresh thyme leaves
1 bay leave
1 teaspoon kosher or sea salt
1 teaspoon sugar
1/2 teaspoon freshly group pepper
1 cup heavy whipping cream

In stockpot, melt butter over medium heat. Swirl to coat bottom of pot and add leaks and onions. Cook, stirring constantly, for 2 mins until slightly softened and well coated with butter. Reduce heat to very low, cover and cook, stirring occasionally for about 30 mins. until leaks and onions are melting soft but not browned. Add the mushrooms and stir to combine. Cover and cook x 10 mins. Raise the heat to medium, stir in the flour, and cook 3 mins. Add the stock, thyme, bay leave, salt, sugar, and pepper. Bring to a simmer, cover partially, and cook for 10 mins longer.

Let soup cool x 10 mins. Discard bay leave. Working in batches, put in food process until a smooth puree. Return puree to pot and add cream. Cook over low heat until heated through, but don’t let boil. Taste and adjust the seasoning. Serves 8
