07 - Transfer the mixture into a greased 9x13-inch baking dish, spreading it out evenly.
08 - Sprinkle remaining cheddar and mozzarella cheese over the casserole. Mix breadcrumbs with melted butter, if using, then sprinkle over the top.

# Expert Tips:

01 -
  • Underneath that golden, crispy top is a gooey, savory center—like a secret comfort hiding in plain sight.
  • The whole meal comes together in one dish, with simple steps and nearly endless ways to make it your own.
02 -
  • If you skip draining the tomatoes, the casserole can turn out watery—learned that one the messy way.
  • Letting it rest before serving really does help the flavors settle and prevents burned tongues in the rush to taste.
03 -
  • Browning the meat deeply adds way more flavor than just cooking it until gray.
  • Don’t skimp on the resting time after baking; the casserole slices hold together so much better.
