I haven’t cooked creamy mushroom soup often over the years and on the occasions that I did, I found that they never quite measured up to my childhood memory. Until now!
For this recipe I combined three types of fresh mushrooms (portobellini, white button, and oyster) with a handful of dried porcini mushrooms. If you do not have dried mushrooms, don’t fret. You may not have the same depth of flavor but the soup will still taste great using chicken stock.
I did not want a typical cream of mushroom soup but did want to add a hint of decadent luxury. To achieve this I made a brown butter roux and added the mushroom broth and lastly the cream, to prevent the cream splitting.
The soup has just enough texture and flavor contrasts to hit the spot. Leftovers, if any, can be frozen and reheated later (after defrosting in the refrigerator), without any change in the flavor. Don’t forget to add the lemon juice and chopped parsley before serving for an extra punch of flavor.
While writing this post I remembered my very first taste of cream of mushroom soup…
Our neighbors had invited us to a holiday resort near Hermanus in South Africa, for Christmas lunch. I was not feeling very well after a spending much of the day in the swimming pool under the hot summer sun, but my parents couldn’t leave me behind, alone in the rondavel. Christmas dinner was being served in the ballroom (the sports hall all dollied up for the occasion), but they were overbooked and set up a few tables in the main dining room and reception area of the resort.
The first course was the most delicious thing I had ever tasted: Cream of mushroom soup. I don’t remember anything else on the menu :). As a five year old who had never tasted mushroom soup before, it was the most exotic thing I could imagine.
In our family home, vegetable and split pea soup with lamb or beef were usually the order of the day, and preferred by everyone else in the household. I was the only one who was not really a fan, until the first time I ate soup in Istanbul on my first visit in March 2000. It was practically obligatory to add a squeeze of lemon to any type of soup served as a first course with lunch or dinner. The acidity of the lemon appeared to enhance the flavors of the slowly cooked vegetables and made it dance on the tongue. I have loved soup ever since.
This mushroom soup recipe combines dried and fresh mushrooms with vegetable stock and cream for an indulgent and warming dish that is hard to beat.
Creamy Mushroom soup
Earthy and rich mushroom soup generously seasoned and topped with a tangy mix of lemon zest, fried mushrooms and parsley
- 4 dried porcini or shitake mushrooms
- 250 ml boiled water approximately 1 cup
- 45 ml vegetable oil approximately 3 tablespoons
- 45 ml butter approximately 3 tablespoons
- 250 grams portobellini mushrooms reserve 3 for garnish
- 250 grams white button mushrooms reserve 3 for garnish
- 100 grams oyster mushrooms reserve 2 for garnish
- 1 onion finely chopped
- 2 stalks celery finely chopped
- 3 cloves garlic finely sliced
- 1000 ml chicken or vegetable stock
- 5ml salt approximately 1 teaspoon
- freshly ground black pepper to taste
- 5 ml fresh thyme OR parsley finely chopped; approximately 1 teaspoon
- 30 ml butter approximately 2 tablespoons, divided
- 15 ml cake flour approximately 1 tablespoon
- 100 ml cream
- 1/2 lemon zest and juice
- 5 ml chopped parsley for garnish approximately 1 teaspoon
In a small bowl, cover the dried mushrooms with a cup of boiling water to completely submerge them and let soak for at least 20 minutes until ready to be added to the soup.
Remove the fresh mushroom stems and chop the caps into a small dice.
The stems can be frozen and used later in another dish.
In a pot, melt the butter in the oil and add the onion and celery and sweat for 10 minutes on medium heat.
Next, add the chopped mushrooms and sauté for 10 minutes before adding the sliced garlic.
When the mushrooms start to release their liquid, add the soaked dried mushrooms that have been chopped up and continue cooking until all the liquid has disappeared.
Add the strained soaking liquid to the mushrooms in the pot with a teaspoon of salt and pepper to taste.
Add the stock and parsley and then bring to the boil and reduce the heat to a simmer for 20 minutes, then remove from the heat.
Set aside a cup of the broth without any mushroom pieces for the roux.
Finely slice the reserved mushrooms and sauté in a hot pan with 1 tablespoon of butter until browned at the edges.
Remove the mushrooms from the pan and add the other tablespoon of butter.
To the melted butter add a tablespoon of flour and stir quickly to cook the roux.
Add the reserved broth a little at a time and whisk continuously until the sauce is thick and smooth.
Add the cream and simmer for another minute.
Blend the soup with an immersion blender or in a stand blender until smooth, adjusting the seasoning if required.
Add the creamy roux to the soup and blend again.
Return the soup back to the heat until it comes to a bubble, before serving.
To serve, garnish with a few sliced mushrooms, a sprinkling of parsley, a pinch of lemon zest and a squeeze of lemon juice in the centre of each bowl. A few slices of crusty bread on the side will be good too.
Choose either thyme or parsley for flavoring as they taste different and may clash when used together.
To make this gluten free use half or third the amount of corn or rice flour for the roux.
