How To Make Cheesy Au Gratin Potatoes

Slice the potatoes and layer them in the slow cooker. Sprinkle with some salt and pepper between the layers.

Grab a medium to large saucepan and add some butter and melt on medium heat. Once the butter melts, add the flour and mix it in with a whisk.

Pour the milk into the pan while whisking. Try to keep whisking until all of the lumps are gone.

Next, add the garlic salt and minced onion to the bowl and mix well. Cook until the sauce is thick.

The sauce will thicken fast–it doesn’t take long, so don’t go fold any laundry (like I always try to do) or anything like that.

Once the sauce thickens add the sour cream and shredded cheddar cheese to the bowl and combine.

Pour the sauce over the potatoes.

I take a spoon and move the potatoes around a little to get the sauce down between layers.

Replace the lid and cook the potatoes for three to four hours on high.

Once you start to see the edges brown and the potatoes are soft, the side dish is done.
