- Choose large button or baby bella mushrooms with deep caps for holding more filling. Clean thoroughly.
- Pack cheese mixture tightly into mushroom caps so it holds together when baked.
- Use high-quality, flavorful cheeses like aged white cheddar and provolone. Shred or dice into small pieces for easy melting.
