Tips
Add gochujang gradually and taste to adjust heat level before assembling sandwiches.
Butter the pan-facing sides of bread for even toasting and prevent sticking.
Good to Know
Mac and cheese filling refrigerates up to 2 days; reheat gently before assembling sandwiches.
Prepare mac and cheese filling up to 2 hours ahead and store warm or reheat before assembly.
Serve immediately while bread is warm and cheese is melted.
Common Mistakes
Do not skip whisking milk slowly into the roux to avoid lumps in the sauce.
Do not let the pasta cook beyond al dente to avoid mushy texture in the finished sandwich.
Do not flip the sandwich too early to avoid cheese escaping before the bread crisps.
