# How-To Steps:

01 - Preheat oven to 375°F. Line a baking sheet with parchment paper.

03 - In a medium bowl, whisk together eggs, milk, salt, and pepper until well combined.

# Expert Advice:

01 -
  • Everything glorious about a breakfast diner sandwich, but somehow better because you made it yourself
  • The way warm melty cheese oozes into flaky croissant layers is the kind of comfort food memory you want to repeat
02 -
  • Overcooked eggs ruin everything—pull them when they still look slightly underdone, because carryover heat finishes the job
  • Letting the assembled sandwiches rest for 60 seconds after baking gives the cheese time to set so it doesnt all slide out when you take that first bite
03 -
  • If your croissants are slightly stale, brush them with a little melted butter and warm them in the oven for 3 minutes before assembling
  • Dijon mustard or herbed cream cheese spread on the inside adds this incredible depth of flavor most people cant quite identify but absolutely love
