A savory mushroom filling with creamy, buttery flavors, enhanced by Worcestershire sauce and thickened to perfection—ideal for making ahead and versatile for sandwiches or pastries.
Ingredients
Instructions
- Saute chopped mushrooms in butter or margarine.
- Add Worcestershire sauce while cooking.
- Add heavy cream and salt to taste.
- Thicken the mixture with flour, adding additional flour if needed.
- Refrigerate the filling. Best made the day before using.
Tips & Substitutions
For an even richer flavor, consider adding minced garlic or shallots while sautéing the mushrooms. If you want a lighter version, substitute half of the heavy cream with low-fat milk or a non-dairy alternative. Using shiitake or portobello mushrooms can enhance the umami flavor. Make sure to sauté the mushrooms until they are golden brown to deepen their flavor.
Serving Suggestions
This mushroom filling is perfect for layering in sandwiches or as a topping for toasted bread. Consider pairing it with a side of mixed greens or serving it alongside Potato Soup With Cucumber for a delightful meal. For a heartier option, use it in a wrap with grilled vegetables or serve it as a dip with crackers.
Storage & Reheating
Store any leftover filling in an airtight container in the refrigerator for up to 3 days. When ready to use, reheat gently on the stove over low heat, stirring frequently to avoid burning. If the filling thickens too much upon refrigeration, add a splash of cream or milk to restore the desired consistency.
