Slow cooker creamy potato casserole. Creamy potato casserole is a creamy casserole with potatoes, ham, garlic, and cheese. This dish is perfect for holidays or weeknight dinners.

I used homemade Alfredo sauce to make this recipe.

Why Cook Potatoes in the Slow Cooker?

A slow cooker is a perfect tool for cooking potatoes because it can cook them evenly and slowly.

The reason why slow cookers are perfect for cooking potatoes is that they can cook them evenly and slowly, which means they will be cooked through without being overcooked. Slow cookers also keep the heat from escaping, which makes them a great choice for cooking potatoes.

The Importance of Cooking Potatoes on Low Heat for Long Periods

Potatoes are a staple in many households and are usually cooked in one of two ways: boiling or microwaving. Boiling potatoes is a fast process but it can leave the potatoes with a soggy texture and overcooked insides. Microwaving them is much quicker than boiling them, but the texture can be uneven and the insides can still be undercooked.

Cooking potatoes on low heat for long periods is an excellent way to cook them without any of these problems. This method will also produce more flavors from the potatoes as they simmer for hours with onions and other spices.

How to Cook Potato Casserole in a Slow Cooker

Cut your Yukon gold potatoes in half lengthwise. Then, cut each half into thick slices. In a slow cooker, put potatoes, ham, Gruyère cheese, onion, and cream cheese. Mix everything until it’s all blended.

In a bowl, mix pasta sauce, mustard, dried thyme and garlic. Stir until everything is blended. Then, pour the sauce over the potatoes in the slow cooker. Put the lid on your slow cooker and turn it to the low-heat setting. Let it cook for 6 to 8 hours.

Turn off the slow cooker. Stir the contents in the cooker until everything is mixed. Put the contents into bowls. If you want, you can add a small thyme branch to make the bowls look pretty.
