Notes & Tips

Roasting Trick: For extra crispiness, broil for the last 3-5 minutes.

Make It Extra Cheesy: Add Parmesan or Swiss cheese to the sauce for more depth.

Dairy-Free Alternative: Use coconut cream instead of heavy cream and nutritional yeast instead of Gruyere.

Mushroom Choices: Shiitake and portobello add more umami, while white button mushrooms are milder.

Storage & Reheating: Store leftovers in an airtight container for up to 3 days. Reheat in the oven at 350°F (175°C) for 10 minutes.
