How To Clean a Casserole Dish with Burnt-On Foods

How To Clean a Casserole Dish

What You’ll Need

  • Spatula (ideally, a plastic one)
  • Baking soda
  • Dish soap
  • Hot water
  • Scrubby sponge


  1. Get to work with a spatula: Scrape off as much food as you can with the spatula. Then, rinse the dish. (Note: We carefully used a metal spatula here, but a plastic one really is best so you don’t scratch the dish.)
  2. Add baking soda: Sprinkle a liberal amount of baking soda along the bottom of the casserole dish.
  3. Add dish soap: Add a couple squirts of dish soap, then fill the casserole dish with piping-hot water. Let it sit on a flat surface for at least 15 minutes, but as long as overnight.
  4. Bring back that spatula: With the baking soda mixture still in there, use your spatula again to scrape off any bits that have started to come loose. Dump out the dirty water.
  5. Add more baking soda: Sprinkle more baking soda onto the surface of the dish, focusing on any particularly bad spots.
  6. And more dish soap: Add a dot of dish soap to your scrubby sponge, turn on the hot water, and get scrubbing!
  7. Repeat as needed: Rinse out your scrub brush periodically as it fills with muck and reapply soap and baking soda as necessary.
  8. Let dry: Let your casserole dish dry fully before you put it away.
