Method
Preparation
- Begin by slicing the mushrooms, dicing the onion, and mincing the garlic to ensure even cooking and flavor blending.
- In a large skillet, heat the butter and olive oil over medium-high heat until bubbling and aromatic.
Cooking
- Add the sliced mushrooms, cooking until golden brown and their moisture evaporates.
- Reduce the heat to medium, mix in the diced onion, and sauté until translucent.
- Stir in the minced garlic and cook for about 1 minute.
- Evenly sprinkle the flour over the mixture, stirring to coat.
- Gradually pour in the vegetable broth while stirring continuously to avoid lumps.
- Stir in the Dijon mustard and soy sauce, then let the sauce simmer for 5–7 minutes as it thickens.
- Lower the heat and gently stir in the sour cream.
- Season with salt and black pepper to taste, then garnish with chopped parsley before serving.
Notes
For a lighter version, substitute sour cream with Greek yogurt. For variations, try using different mushrooms and consider gluten-free options by replacing flour with cornstarch.
