Tips
Use medium or large shrimp for the best texture - they hold up better during baking and provide satisfying bites.
Don't skip the flour cooking step as it prevents the sauce from separating and ensures a smooth, thickened base.
Serve immediately while hot and bubbly for the best creamy texture and optimal cheese pull.
