Best 4 Slow Cooker Potatoes Au Gratin Recipes

CROCK-POT AU GRATIN

Steps:

• In a medium sauce pan over medium heat, melt butter. Add flour and cook 1-2 minutes until no longer raw, whisking frequently. Add whole milk and whisk again. Bring to a simmer and let bubble until thickened slightly, 3-4 minutes. Season with garlic powder, salt, and pepper and remove from heat. Whisk in cheddar and 1/4 c parmesan and whisk until smooth.
• Spray the bowl of your Crock-Pot with nonstick cooking spray. Add a small spoonful of cheese sauce on the bottom of Crock-Pot bowl. Create your first layer of sliced potatoes, overlapping them slightly, until a completer layer is formed. Spoon over more cheese sauce (about a 1/4 c) and sprinkle with about 2 tablespoons of the remaining parmesan. Continue layering until all potatoes, cheese sauce, and parmesan are used, ending on parmesan.
• Place slow cooker on high and cook until potatoes are tender, 2 1/2 to 3 hours, checking halfway to make sure the potatoes aren't burning. When finished, remove Crock-Pot insert if oven friendly and broil if desired. Garnish with parsley and serve.

CROCK POT POTATO AU GRATIN

Steps:

• Wash OR peel your potatoes. Slice to 1/8" thick, set aside. (I like to leave the peel on my potatoes)
• Generously coat slow cooker with non-stick spray.
• In a medium saucepan melt the butter over medium-low heat. Add flour and whisk to combine. Whisk in the milk, garlic powder, pepper, and a generous amount of salt. (I use at least a teaspoon.) Cook stirring frequently just until it starts to thicken. Remove from heat and stir in cheeses.
• Place 1/3 of the sliced potatoes in the bottom of the slow cooker. Sprinkle with 1/3 of the chopped onion. Pour 1/3 of the cheese sauce over the potatoes and onions. Repeat this 2 more times. Cover and cook on high for 3-4 hours or low for 4-6 hours or until potatoes are tender. Let sit 20 minutes before serving.

CROCKPOT AU GRATIN POTATOES

Steps:

• VERY generously spray your slow cooker with nonstick spray. I used a 6-quart slow cooker for the recipe. Note that smaller crockpots may not be able to cook through all the potatoes evenly so you will have to halve (or cut in thirds) this recipe.
• Wash and peel the potatoes. Cut into medium thick slices (see picture for general width). Measure the potatoes -- you should have about 5 cups total.
• Place a layer of potatoes at the bottom of the crockpot. Generously (or to your preference, but don't skimp on the salt or it will be more bland) sprinkle on seasoned salt and pepper. Layer another layer of potatoes and sprinkle on salt and pepper. Repeat this process until all the potatoes are layered in the crockpot.
• In a medium-sized pot over medium heat, add in the butter. Melt completely and then vigorously whisk in the flour until a thick dough forms. Whisk constantly for 1 minute. Add in the garlic and onion powder and continue to whisk.
• Very slowly add in the milk whisking as you add it. In between milk additions whisk the mixture and allow it to thicken.
• Once all the milk is added in and the mixture is completely smooth and thick, add in the sour cream. Whisk to add. Add in the freshly grated cheddar cheese and whisk until completely melted and the mixture is smooth.
• Add some more salt and pepper here if desired.
• Pour this cheese sauce evenly over the potatoes. Shake the slow cooker to get the creamy cheese sauce evenly throughout the crockpot. Do not stir it in.
• Place 3 paper towels on top of the crockpot (this will absorb lots of moisture and keep the potatoes crispier) and then place on the lid.
• Place on high (my experimentation with low heats were unsuccessful.) for 3-5 hours depending on the heat of your slow cooker. Slow cookers cook at different temperatures and speeds! Mine took just under 3 hours -- check frequently to avoid burning the edges or over cooking the potatoes so they are mushy.
• Halfway through the cooking time, change out the paper towels for fresh ones.
• Once the potatoes are tender and cooked through, remove the lid and garnish with fresh parsley or chives and additional seasoned salt and pepper. Allow to cook without the lid for 15-20 minutes to get a bit crisper on top if desired.
• This recipe is for classic au gratin potatoes -- feel free to add more toppings or seasonings as you enjoy your au gratin potatoes. Some ideas are to chop up an onion and add that in (I would sauté it in olive oil first), add some red pepper flakes for heat, some cooked and chopped bacon, paprika, more or different flavors of cheeses...

SLOW COOKER POTATO, LEEK, AND KALE GRATIN WITH TOO MUCH CHEESE

Steps:

• Set the slow cooker to the sauté function. Add the oil and, once hot, add the leek and cook for 1-2 minutes, then add the kale and continue cooking for another 2-3 minutes, or until the leek is soft. Gently scoop into a bowl. Line the slow cooker with a sheet of baking paper, working carefully as it will be hot.
• Add the cream, stock and cheeses to a bowl and use a fork to combine.
• Arrange one-third of the potato slices over the bottom of the lined bowl, overlapping them slightly. Pour in one-third of the cream mixture and sprinkle with one-third of the leek mixture. Season and repeat the process until all the ingredients have been used.
• You should get three decent layers of cheesy potato goodness. Close the lid and cook on high for 4 hours.
• Check the liquid at the 3-hour mark. If there is a lot of liquid remaining, leave the lid off for the last hour of cooking. If, at 4 hours, there is still too much liquid, remove the lid and, if your cooker has it, hit the reduce function, or simply the sauté function, and cook for 2-5 minutes. This will quickly get rid of any excess moisture.
• Allow to cool for at least 15 minutes in the slow cooker before gently removing. If you try to cut it when still hot, it tends to go everywhere. Alternatively, scoop the gratin straight from the bowl onto the plate. It might not look amazing, but it's the kind of dish that is here for a good time, not a long time.
• Season generously with salt and pepper and serve. Eat wearing stretchy pants; you are going to need them.
