💭What are company potatoes?

Company potatoes are a fancy term given to a mashed potato casserole that can be made ahead of the time you're planning on serving them. Usually a day or two in advance.

They're not to be confused with "funeral potatoes" that are made with frozen hash browns. These are real potatoes and a few extra added ingredients to make them a little more special than regular Sunday dinner mashed potatoes.

Start by boiling the potatoes until they're soft, then mash them with some butter, half and half, cream cheese and salt to taste. Once they're mashed to your liking, transfer the potatoes to a baking dish and cover with foil.

When you're ready to eat, simply reheat the potatoes in the oven or microwave until they're warm throughout. This easy hack will save you precious time on Thanksgiving so that you can enjoy spending time with your loved ones.

💭What's a potato ricer?

A potato ricer is a kitchen gadget that is used to create light and fluffy mashed potatoes. It consists of a handheld device with a series of small holes that can be squeezed together.

To use a potato ricer, the cook simply boils potatoes until they are soft, then puts them through the ricer one at a time. The cooked potatoes will come out in long, thin strands that can be easily mixed with other ingredients.

Potato ricers can also be used to make other dishes, such as cauliflower mash or pumpkin puree. They are often used by professional chefs to create smooth, consistent results. For home cooks who want to make perfect mashed potatoes, a potato ricer is an essential tool.

💭How to make mashed potatoes ahead of time?

You can definitely make mashed potatoes ahead of time! If you don't want to follow this creamy recipe below, simply make the mashed potatoes ahead of time and reheat them when you're ready to serve. You can reheat the potatoes in the microwave until they're warm throughout.

Main Ingredients Needed

Be sure to see the recipe card for exact quantities, detailed instructions and special notes.

• Russet or Yukon gold potatoes
• Butter
• Cream cheese softened
• Half-and-half
• Salt and pepper

Step-by-Step Directions

Step 1 | Prepare the Potatoes

• Peel and cut the potatoes and add them to a large pot of water.  Bring to a boil and cook until the potatoes are fork tender. Drain the potatoes thoroughly in a large colander. Place them back into the dry pot and mash the potatoes using an electric mixer.  A potato ricer works well too.
• Using your hand held electric mixer, add the butter, cream cheese and about ½ cup of half-and-half and mash. Adding more of the half-and-half as needed.  (I usually use the whole amount). Season with salt and pepper.

Step 2 | Add Potatoes to Casserole Dish

• Transfer the potatoes to a 9X13 size casserole dish that has been sprayed with non-stick cooking spray.
• Add a few tablespoons of butter over the top of the potatoes.
• Cover them with plastic wrap and/or aluminum foil and place in the refrigerator. 

Step 3 | Baking Instructions

• Remove the casserole dish from the refrigerator about an hour before you need to serve them. Allow them to come to room temperature, about 30 minutes or so.
• Bake in a preheated 350 degree oven for about 30 to 40 minutes, or until heated through. 

They look great on the buffet table.  And you don't have to peel potatoes Thanksgiving morning.  There are so many other things you need to be doing instead of peeling potatoes!

💭Preparing mashed potatoes ahead of time

• Always make sure you fill the pot with cold water. Make sure the potatoes are completely covered as well. 
• If you are preparing the potatoes ahead of time, allow them to sit out on the counter for at least 30 minutes to come to room temperature the next day before baking in the oven. This is especially important if you're using a glass baking dish. You should never put a glass baking dish directly from the refrigerator into the oven. You need to allow the contents of the casserole dish to come to room temperature so there's no chance of the glass casserole dish shattering when it's suddenly exposed to high heat from an oven. 
• Mix up the seasonings by adding garlic, bacon and cheddar cheese. 
• You can even try flavored cream cheese instead of the traditional cream cheese used in this recipe. I think cream cheese with chives would be delicious!
