It’s March which means it’s almost St. Patrick’s Day! Sure, the Americanized version of the holiday is nothing even close to the actual Irish celebration, but it is a good excuse for some amazing potato food! With that being said, along came the Irish Potato Casserole. When it’s not close to St. Patrick’s Day, I just call this my mashed potato casserole, since that’s basically what this is.

Justin’s family is of Irish descent. We decided one year we needed to make something to celebrate besides having Guinness and Baileys! I really don’t know just how Irish this potato casserole really is, but we enjoy it. Potatoes are one of my favorite foods. In high school, I would come home and my snack-of-choice was usually a bag of instant mashed potatoes!

I started searching for some Irish recipes and came across a few that I combined into this delicious dish. It can serve as a main course or a side dish. We often make it as a main dish when it is just us. But I have made it as a side when we have other people over. This makes an entire 9×13 casserole dish full of potatoes, so it’s a lot to eat.

Luckily, it does reheat pretty well so we will eat the leftovers the next day. I just like to add a bit more butter when I reheat to help bring the creaminess back into the potatoes.

Irish Potato Casserole Step by Step

Ingredients

  • 8-10 red potatoes
  • 8 oz cream cheese
  • 8 oz sour cream
  • 1/2 cup butter
  • 1/2 tsp salt
  • 1/4 cup fresh chives (chopped)
  • 1 pinch Paprika
  • 1 tsp onion powder
  • 1 tsp garlic powder
  • 1 cup cheddar cheese (shredded)

Instructions

Cut the potatoes into cubes and place in a large stockpot. Fill with enough water to cover the potatoes and bring to a boil. Reduce the heat to medium-low, cover, and simmer for 20 minutes or until the potatoes are fork-tender.

Preheat the oven to 350F when the potatoes are almost done cooking.

Meanwhile, in a large mixing bowl, add all of the other ingredients. You can start to mix them now, but if you wait until the potatoes are in there it softens everything and makes it easier to mix.

When the potatoes are done, drain the pot then add the potatoes to the large mixing bowl. Use a potato masher to thoroughly combine everything.

Spoon the potato mixture into a 9×13 glass baking dish and smooth with a rubber spatula.

Bake for about 30 minutes, until the edges are bubbling. Serve warm.

Irish Potato Casserole Leftovers

Storage: You can keep extra Irish Potato Casserole in covered containers in the refrigerator for up to 5 days.

Reheating: The best way to reheat the casserole is in a saucepan over medium-low heat, stirring frequently, until it’s warmed through. If it starts to dry out you can add a bit of butter.

Freezing: This casserole does not freeze well because of the starchy potatoes.

  1. 5 minutes prep time to peel and shred 2 cups of potatoes, beat some cream, mince onion, shred 1/2 cup cheese? Let’s get real. Like the recipe.

    1. Excellent! I’ve made this and variations thereof for years. I sometimes add dill and or garlic – some green onions makes it rather like a champ casserole its a great side for holidays – For my own taste though, I do use double the potatoes – this is an excellent recipe. thanks!

      1. I’ve never heard of champ casserole before, but when I just looked it up, the two do seem very similar. I’ll have to try the dill, garlic, and green onions next time, those do sound like a great addition!

  2. 5 stars
    This is delicious! I made it today for lunch and my family loved it. Thanks for sharing, didn’t take much time to prep which I loved.

    1. I’m so glad your family enjoyed this! It’s so hard to gauge the prep time since it depends on how fast the potatoes cook. I prefer to overestimate so it doesn’t take anyone by surprise.

  3. Seriously, it’s like you looked deep into my soul and published this just for me. My love for potatoes is infinite but my method of preparing them isn’t. I’ve never made anything like this and can’t wait to try this!

  4. Potatoes are a staple in this house, but I have never made this before. I make a lot of potato salad honestly. This casserole looks like it would be incredible!
