I remember the first time I made this for a potluck. I was nervous, honestly, because my grandma's recipe was legendary in our family. The smell alone — that bubbling cheese, the buttery breadcrumbs — had people drifting into the kitchen like they were hypnotized. This isn't the boxed stuff; this is the real deal, the kind that sticks to your ribs and makes you feel like everything's going to be okay. It's rich, it's comforting, and yes, it takes a little effort, but trust me, it's worth every minute. You'll want to eat it straight from the dish while it's still bubbling hot.
Okay, real talk — don't skimp on the cheese. I tried using pre-shredded once because I was in a rush, and it was a sad, grainy mess. Use blocks and grate it yourself, hon. Also, if you burn the roux even a tiny bit, start over. I learned that the hard way and cried a little. And please, for the love of all things good, let it rest for at least 10 minutes after baking. I know it's torture, but cutting into it too soon means cheesy lava everywhere. Totally worth the wait.
