This recipe is one of my family’s favorite comfort food casseroles. The zesty taste of peppers onions, cheese blend with a so well we just can’t get enough of it. In our house there usually aren’t any leftovers to spare.

Why is this dish called Funeral Potatoes?

This casserole is also known as funeral potatoes because it is a popular comforting dish to bring to the home of someone who has lost a family member.

This potato au gratin potatoes side dish is also great for brunch as a hash brown casserole as well as a dinner potato side staple.

There are a ton of versions of these cheesy potatoes out there, some made with traditional hash browns or fresh shredded potatoes. Others with cream of mushroom instead of cream of celery.

I hope you will love it as much as we do! Here’s our version of the popular dish.

    1. Candice Sampson says:

      How long and what temp in the crock pot?

      1. Candice, I have not made this in a crockpot, this recipe is for baking in an oven. I do not know how long or what temp it would do well in a crockpot.

  6. I love how comforting these are! Cheesy potatoes are my total weakness, so I don’t think a pan would be safe near me – YUM! :)
