This hearty and flavorful Russian Mushroom and Potato Soup is a comforting classic. Packed with vegetables and creamy broth, it’s perfect comfort food for chilly evenings.
Melt 3 tablespoons butter in a large saucepan over medium heat. Add leeks and carrots, cooking for 5 minutes until they start to soften and become fragrant.
Pour in chicken broth and season with dried dill, salt, pepper, and bay leaf. Bring to a gentle boil.
Add diced potatoes, cover, and cook for 20 minutes or until potatoes are tender but firm when pierced with a fork. Remove and discard bay leaf.
While potatoes cook, melt remaining 2 tablespoons butter in a skillet over medium heat. Sauté mushrooms for 5 minutes until golden brown and moisture has evaporated.
Stir the sautéed mushrooms into the soup pot, combining all flavors.
In a small bowl, whisk half-and-half and flour until completely smooth with no lumps visible.
Slowly stir cream mixture into soup to thicken until it coats the back of a spoon. Taste and adjust seasoning. Garnish with fresh dill and serve.
Notes
Cut potatoes into similar-sized pieces for even cooking. Don’t overcook – they should be tender but firm.
Don’t overcrowd skillet when sautéing mushrooms for better browning and texture.
Whisk flour and half-and-half mixture completely smooth to prevent lumps in the finished soup.
