Brandi’s Key Ingredients

What Type of Potatoes to Use

Yukon Gold or Russet potatoes are the best choices for mashed potatoes. Yukon Gold potatoes have a naturally buttery flavor and smooth texture, making them perfect for creamy mashed potatoes. Russet potatoes are starchy and yield fluffy mashed potatoes. You can also use a combination of both for the perfect blend of creaminess and fluffiness!

Red potatoes have a waxy texture, which results in a slightly denser and creamier mash compared to starchy varieties like Russets. They hold their shape well, so the mashed potatoes will be a bit chunkier, making them great if you prefer a more rustic texture.

How to Season the Potatoes

Potatoes are bland on their own. Spices and salt are a must. I love to use garlic powder, onion powder, salt, and pepper.

Other spices I love to add from time to time are smoked paprika, Cajun Seasoning, or Creole seasoning for extra flavor and a twist.

Do You Leave the Skin on the Potatoes

If you’re using red potatoes or Yukon Gold potatoes, their thin skins can be left on for added texture, color, and nutrients, giving the mashed potatoes a more rustic look and feel.

However, if you’re aiming for a smoother, creamier texture, or if you’re using Russet potatoes with thicker skins, it’s often better to peel them before cooking. Ultimately, it’s a personal choice based on the texture and appearance you prefer!

The skin has lots of nutrients, so it’s beneficial. 

How to Make No Boil Slow Cooker Crockpot Mashed Potatoes

Detailed measurements and full instructions can be found in the recipe card at the bottom of this post.

1. Add diced potatoes and broth to the slow cooker.
2. Slow cook until the potatoes are soft and tender.
3. Open the slow cooker. Do not drain the broth the potatoes were cooked in. Mash the potatoes with a potato masher.
4. Add buttermilk (or cream or milk), sour cream or Greek yogurt, and spices. Stir until combined.

Cook Time/How Long to Cook

Cook on High for 3-4 hours or Low for 6-7 hours. Cook until the potatoes are soft and tender. It takes 3 hours for me.

Do Not Overwork the Potatoes

Once the potatoes are cooked it’s time for mashing. Be careful not to over work the potatoes and mash them more than necessary. This will cause them to become gluey and gummy. Potatoes contain starch, and when they’re mashed or mixed too vigorously the starch granules break down too much, releasing excess starch.

This creates a sticky, undesirable texture instead of the light and fluffy mashed potatoes you’re aiming for. To avoid overworking them, use a gentle hand when mashing, and use a potato masher to achieve the perfect consistency.

How to Prevent Soupy Potatoes

After cooking the potatoes in the Crockpot, make sure to thoroughly drain any excess water or broth. Let the potatoes sit in the colander for a few minutes to ensure all liquid is removed. Cook the potatoes until just fork-tender. Overcooking them can cause them to absorb too much water, leading to a mushy or soupy texture. Mash the potatoes while they’re still hot. Cold or cooled potatoes can release more water when mashed, leading to a runnier consistency.

What Type of Milk or Cream to Use

My favorite ingredient is buttermilk. Buttermilk has lactic acid that will result in creamy and fluffy mashed potatoes. It’s a game-changing ingredient. My second favorite is heavy whipping cream. Either of these can be substituted with half and half or milk.

Half and half and milk aren’t as thick and rich as buttermilk or cream, so the use of it will alter the texture of the potatoes.

Ideas for Add-ins and Substitutions

• Grated Parmesan cheese
• Cream Cheese
• Cheddar or gouda cheese
• Green Onions
• Roasted Garlic
• Herbs (fresh parsley, thyme, chives, or rosemary)
• Caramelized onions
• Bacon
• Horseradish
• Dijon Mustard
• Truffle oil
• Mashed roasted vegetables (carrots, parsnips)
• Sautéed mushrooms
• Paprika
• Breadcrumbs
• Chili Flakes or Hot Sauce

How to Keep the Potatoes Warm in the Crockpot

If you plan to serve these immediately or the same day, leave them in the Crockpot on the Keep Warm Setting. If you are reheating them from cold, add them to the slow cooker on High until warm. Then switch it to the Keep Warm setting until you plan to serve.

Can You Make Them Ahead?

If you are preparing mashed potatoes for the holiday or any big event you may be overwhelmed. Determining what can be made in advance is a game changer. You can make this dish a couple of days in advance and it will also free up your oven and stove with the use of the slow cooker.

Once mashed, allow the potatoes to cool slightly and transfer them to an airtight container. Store the mashed potatoes in the refrigerator for up to 2-3 days before serving.

How to Store/How Long Will They Last in the Fridge

Store the potatoes in the fridge tightly covered and sealed. For best results, serve within 2 days, but they will last in the fridge for 3-4 days.

How to Reheat

On the day you plan to serve, return the mashed potatoes to the crockpot and set it on low for 2-3 hours, stirring occasionally until heated through. Add a bit of milk or butter to refresh the texture if needed.

Freezer Tips

You can freeze these tightly sealed and they are best when used within a month. After that, they will start to get freezer burned and form ice crystals. Defrost overnight in the fridge.
