Ingredients:
- 4 tbsp (56g) unsalted butter
- 1 lb (450g) cremini or button mushrooms, sliced
- 1 medium (110g) yellow onion, finely diced
- 3 cloves (9g) garlic, minced
- 1 tsp (2g) dried thyme
- 1/4 tsp (1.5g) ground nutmeg
- 3 tbsp (24g) all-purpose flour
- 3 cups (710ml) vegetable or chicken broth
- 1 cup (240ml) heavy cream
- 1 tsp (6g) salt
- 1/2 tsp (1g) black pepper
Instructions:
- Melt 2 tbsp (28g) of butter over medium-high heat. Add the sliced mushrooms in a single layer and let them sit undisturbed for 3–4 minutes until they develop a deep golden-brown color. Stir and cook for another 3 minutes until moisture has evaporated. Remove mushrooms from the pot and set aside.
- In the same pot, add the remaining 2 tbsp (28g) of butter. Sauté the diced onion until translucent (about 4 minutes). Stir in the minced garlic and thyme, cooking for 60 seconds until fragrant.
- Whisk in the flour and cook for 2 minutes to remove the raw flour taste until the mixture forms a bubbling golden paste.
- Slowly pour in the broth while whisking constantly to prevent lumps. Return the seared mushrooms to the pot and simmer on low heat for 10 minutes.
- Stir in the heavy cream, nutmeg, salt, and pepper. Use an immersion blender to pulse the soup until mostly smooth but still containing small, rustic chunks of mushroom.
