Method
- Melt butter in a large pot over medium heat. Add onions and cook until soft, 4–5 minutes.
- Add mushrooms and cook until they release liquid and brown, about 6–8 minutes.
- Stir in garlic and flour; cook 1 minute to remove raw taste.
- Pour in broth slowly, stirring to avoid lumps. Add thyme.
- Simmer 10 minutes, then blend half the soup for creaminess or use an immersion blender.
- Stir in milk, heat gently, and season to taste.
