# How-To Steps:

01 - Preheat oven to 400°F and lightly grease a 9x13-inch baking dish.

09 - Bake 35 to 40 minutes until crust is golden and filling bubbles.
10 - Allow casserole to rest 10 minutes before slicing and serving.

# Expert Tips:

01 -
  • It comes together in under an hour and feels like comfort incarnate on a plate.
  • One dish means you're not standing at the stove juggling five pans, just pure, uncomplicated coziness.
  • Leftovers taste even better the next day, which is genuinely rare and wonderful.
02 -
  • Don't skip the resting time at the end; it lets everything set just enough so you get clean, gorgeous slices instead of a delicious mess.
  • The egg wash is what makes people think you're fancy; it's the difference between homemade and homemade-looking, and it takes literally 30 seconds.
03 -
  • Letting the finished casserole rest for 10 minutes before cutting into it is the one trick that separates a sliceable dinner from one that falls apart on the plate.
  • If your crust is browning too fast, loosely tent it with foil for the last 10 minutes of baking, and it'll emerge perfect every time.
