Why You’ll Love This Recipe

These Slow Cooker Mashed Potatoes will quickly become your go-to side dish for countless reasons. First, the hands-off cooking method means you can focus on other dishes while your potatoes slowly transform to perfection. The gentle, even heat of the slow cooker prevents the scorching that sometimes occurs on stovetops, resulting in consistently smooth potatoes every time.

The texture contrast is what truly sets this recipe apart – a silky interior with just the right amount of substance to support pools of gravy or melted butter. Each bite delivers that perfect balance of creaminess and potato flavor that store-bought versions simply can’t match.

For busy hosts, these crockpot mashed potatoes offer game-changing convenience. You can prepare them hours ahead of mealtime and keep them warm without sacrificing quality. The slow cooker method also infuses the potatoes with richer flavor as they absorb the butter and seasonings gradually during the cooking process, resulting in depth of flavor that quick-cooking methods can’t achieve.

Ingredients

• 5 pounds (2.3 kg) Russet potatoes, peeled and cut into 1-inch chunks
• 1 cup (240 ml) chicken broth or vegetable broth
• 4 tablespoons (56g) unsalted butter, cubed
• 1 tablespoon (18g) salt, divided
• 1 cup (240 ml) whole milk, warmed
• 4 ounces (112g) cream cheese, softened
• ½ cup (120 ml) sour cream
• ¼ teaspoon (1g) white pepper
• 2 cloves garlic, minced (optional)

Russet potatoes create the fluffiest texture, but Yukon Golds offer a naturally buttery flavor and creamier consistency. The combination of cream cheese and sour cream provides the perfect tangy richness that elevates these Slow Cooker Mashed Potatoes beyond ordinary recipes. Warming the milk before adding prevents the potatoes from cooling down and helps maintain that silky-smooth consistency that makes this dish irresistible.

Pro Tips

Cut potatoes uniformly. For even cooking, ensure all potato chunks are approximately the same size (about 1-inch cubes). Inconsistent sizing leads to some pieces overcooking while others remain undercooked, resulting in lumpy potatoes.

Don’t overmix. The secret to fluffy Slow Cooker Mashed Potatoes is gentle handling. Overmixing activates the potatoes’ starch, creating a gluey, paste-like consistency. Use a potato masher first, then switch to a wooden spoon or rubber spatula for incorporating dairy ingredients. Save the hand mixer for a final quick blend at low speed if you prefer ultra-smooth potatoes.

Temperature matters with dairy. Always add room temperature or slightly warmed dairy products to your potatoes. Cold ingredients not only cool down your potatoes but can also cause them to seize up and become grainy. For the creamiest texture, allow butter, sour cream, and cream cheese to come to room temperature before adding, and warm the milk slightly on the stovetop or in the microwave.

Instructions

Step 1: Prepare the potatoes by peeling and cutting them into 1-inch cubes. Rinse them under cold water to remove excess starch, then drain thoroughly.

Step 2: Grease your slow cooker with butter or cooking spray. Add the potato chunks, chicken broth, half the salt, and minced garlic (if using). Dot the surface with half of the cubed butter.

Step 3: Cover and cook on HIGH for 3-4 hours or LOW for 6-7 hours. The potatoes are done when they easily break apart when pierced with a fork. Avoid lifting the lid during cooking as this releases essential heat and moisture.

Step 4: Once potatoes are fork-tender, drain any excess liquid, reserving about ¼ cup of the cooking liquid. Return the potatoes to the slow cooker and mash directly in the pot using a potato masher until most lumps are gone.

Step 5: Add the warmed milk, remaining butter, softened cream cheese, and sour cream. Gently fold these ingredients into the potatoes with a wooden spoon or rubber spatula. For completely smooth Slow Cooker Mashed Potatoes, you can use a hand mixer on low speed for just 30 seconds.

Step 6: Season with remaining salt and white pepper, tasting and adjusting as needed. If the potatoes seem too thick, incorporate small amounts of the reserved cooking liquid until you reach your desired consistency.

Step 7: Keep your Slow Cooker Mashed Potatoes on the WARM setting for up to 4 hours before serving. If they begin to dry out, stir in a splash of warm milk or butter to refresh the texture.

Variations

Loaded Slow Cooker Mashed Potatoes: Transform your basic Slow Cooker Mashed Potatoes into a crowd-pleasing favorite by stirring in 1 cup of shredded cheddar cheese, ½ cup of cooked, crumbled bacon, and ¼ cup of sliced green onions just before serving. Top with additional cheese, bacon bits, and a dollop of sour cream for a potato side dish that could easily be the star of your meal.

Roasted Garlic and Herb: For an elevated flavor profile, add a full head of roasted garlic (mashed into a paste) and 2 tablespoons of fresh herbs like chives, rosemary, and thyme to your finished Slow Cooker Mashed Potatoes. The roasted garlic adds a sweet, mellow depth that balances beautifully with the fresh herbs.

Dairy-Free Option: Create creamy Slow Cooker Mashed Potatoes without dairy by substituting the milk with unsweetened almond milk or chicken broth, and replacing butter with olive oil or vegan butter. Instead of sour cream and cream cheese, use dairy-free yogurt and a splash of lemon juice to achieve that tangy richness.

Storage and Serving

Store leftover Slow Cooker Mashed Potatoes in an airtight container in the refrigerator for up to 4 days. To reheat, place in a microwave-safe dish, add a splash of milk or butter, cover, and heat at 50% power, stirring occasionally until warmed through. Alternatively, reheat in a covered casserole dish in a 325°F oven for about 20 minutes.

These potatoes can also be frozen for up to 3 months in freezer-safe containers. Thaw overnight in the refrigerator before reheating using either method above.

For serving, try these perfect pairings:

• Create a mashed potato bar with various toppings like caramelized onions, cheese, herbs, and gravy for a fun, interactive dinner
• Serve alongside roasted chicken or turkey for a classic comfort meal
• Use as a base for shepherd’s pie or top with braised short ribs and their sauce for an impressive dinner

FAQs

Can I peel the potatoes ahead of time?
Yes, you can peel and cut potatoes up to 24 hours in advance. Store them completely submerged in cold water in the refrigerator to prevent browning. Drain and pat dry before adding to the slow cooker.

Why did my mashed potatoes turn out gummy?
Gummy texture usually results from overworking the potatoes, which activates excess starch. To avoid this, use a gentle touch when mashing and folding in ingredients, and avoid using a food processor, which can quickly overprocess potatoes.

Can I double this recipe?
Yes, this Slow Cooker Mashed Potatoes recipe can be doubled if your slow cooker is large enough (6 quarts or larger). Increase cooking time by approximately 1 hour and check for doneness before mashing.

What’s the best potato variety to use?
Russets create fluffy, light potatoes while Yukon Golds produce creamier, slightly denser results. For the best of both worlds, use a 50/50 combination of both varieties in your Slow Cooker Mashed Potatoes.

Can I make these potatoes a day ahead?
Absolutely! Make the potatoes completely, then refrigerate. Reheat in the slow cooker on LOW for 1-2 hours before serving, adding a little warm milk or butter if needed to refresh the texture.
