Mashed potatoes are a classic side dish beloved by many for their creamy texture and comforting taste. However, preparing them can be time-consuming, especially when juggling other dishes for a large meal. Enter the make-ahead slow cooker mashed potatoes recipe—a game changer for anyone looking to save time and oven space. This method not only simplifies the cooking process but also keeps the potatoes warm and ready to serve whenever you are. Let’s dive into the recipe and some tips for perfect make-ahead slow cooker mashed potatoes.


5 lbs of potatoes (Russet or Yukon Gold), peeled and cut into chunks
1 cup chicken broth or vegetable broth (for a vegetarian option)
1 cup sour cream
1/2 cup milk (adjust based on desired consistency)
1/4 cup unsalted butter
Salt and pepper to taste
Optional: garlic, chives, cheese for added flavor


Prep the Potatoes: Start by peeling your potatoes and cutting them into even chunks. This ensures they cook evenly in the slow cooker.

Cooking: Place the potato chunks into the slow cooker. Add the chicken or vegetable broth and a generous pinch of salt. The broth not only adds flavor but also helps the potatoes cook perfectly. Cover and cook on high for 4-5 hours or on low for 7-8 hours, or until the potatoes are very tender.

Mashing Time: Once the potatoes are tender, add the butter, sour cream, and milk to the slow cooker. Use a potato masher to mash the potatoes to your desired consistency. If you like your mashed potatoes extra smooth, you can use an electric mixer, but do so with caution to avoid over-mixing.

Seasoning: Taste your mashed potatoes and season with salt and pepper as needed. This is also the time to add any optional ingredients like roasted garlic, chives, or grated cheese for extra flavor.

Keep Warm: The beauty of using a slow cooker is that you can keep your mashed potatoes warm until you’re ready to serve. Just switch the slow cooker to the ‘warm’ setting, and they’ll stay perfect for hours.

Serving: Serve the mashed potatoes in a large bowl. They’re perfect as a side for nearly any main course, from roasted meats to vegetarian dishes.

Tips for Success:

Choosing Potatoes: Russet and Yukon Gold potatoes are the best choices for mashed potatoes due to their texture and flavor.

Broth for Flavor: Using chicken or vegetable broth adds an extra layer of flavor to the potatoes, making them more savory.

Dairy Temperature: For the creamiest mashed potatoes, warm the milk and melt the butter before adding them to the potatoes. This helps them integrate more smoothly.

Make-Ahead Magic: You can peel and cut your potatoes the night before. Just keep them submerged in water in the refrigerator to prevent browning.

Flavor Variations: Feel free to get creative with your mashed potatoes. Roasted garlic, cooked bacon bits, different cheeses, and fresh herbs can all add unique flavors to your dish.

This make-ahead slow cooker mashed potatoes recipe is not only a time-saver but also a delicious addition to any meal. It frees up your stove and oven, keeps the kitchen cooler, and delivers creamy, flavorful mashed potatoes every time. Whether you’re preparing a feast for a holiday or just a regular family dinner, these mashed potatoes will surely be a hit.

Customizing Your Mashed Potatoes:

Mashed potatoes are like a blank canvas, offering endless possibilities for customization.

Depending on your taste preferences or the occasion, you can add various ingredients to transform the basic recipe into something special. Here are a few ideas:

For a Garlic Twist: Roast a head of garlic wrapped in foil in the oven at 400°F (200°C) for about 30-40 minutes, until soft. Squeeze the soft garlic cloves out of their skins and mash them into the potatoes for a subtle, sweet garlic flavor.

Cheesy Delight: Stir in a cup of shredded sharp cheddar, Gruyère, or your favorite melting cheese just after mashing. The heat from the potatoes will melt the cheese, creating a gooey, cheesy texture.

Loaded Mashed Potatoes: Fold in cooked, crumbled bacon, chopped green onions, and shredded cheese after mashing. Top with a dollop of sour cream for a play on loaded baked potatoes.

Herb-Infused: Fresh herbs can dramatically change the flavor profile of your mashed potatoes. Stir in finely chopped chives, parsley, or rosemary for a fresh, aromatic touch.

Lighter Version: For a lighter version of mashed potatoes, you can substitute Greek yogurt for the sour cream and use a low-fat milk. This will reduce the calorie count while still providing a creamy texture.

Storing and Reheating:

If you find yourself with leftovers or you intentionally made a large batch for future meals, storing and reheating your mashed potatoes properly is key to maintaining their texture and flavor.

Storing: Cool the mashed potatoes completely before transferring them to an airtight container. They can be stored in the refrigerator for up to 5 days.

Freezing: Mashed potatoes freeze surprisingly well. Spoon them into a freezer-safe bag or container, remove as much air as possible, and freeze for up to 2 months. Thaw overnight in the refrigerator before reheating.

Reheating: To reheat, you can use the microwave, oven, or stovetop. If using the microwave, stir occasionally to ensure even heating. For the oven, place the potatoes in an oven-safe dish, cover with foil, and heat at 350°F (175°C) until warm (about 20-30 minutes). On the stovetop, reheat over low heat, adding a bit of milk or butter to moisten the potatoes.

Make-ahead slow cooker mashed potatoes are a convenient, delicious, and versatile side dish that can ease kitchen stress during big meals and add comfort to any dinner. With the ability to customize the basic recipe to suit any taste and the option to keep them warm until serving, this method is a practical solution for both everyday meals and special occasions. Whether you stick to the classic recipe or experiment with various add-ins, these mashed potatoes are sure to be a crowd-pleaser.
