Tips & Variations

• For extra flavor, add chopped fresh herbs like thyme or parsley to the cheese mixture.
• Use a mix of mushrooms for a richer taste, such as shiitake or portobello along with crimini.
• To add a crunchy topping, sprinkle additional panko breadcrumbs or chopped nuts before baking.
• For a lighter version, substitute sour cream with Greek yogurt.

Store leftovers in an airtight container in the refrigerator for up to 3 days. Reheat in the oven at 350 degrees Fahrenheit until warmed through to maintain the crispy topping. Avoid microwaving for best texture.
