There’s something magical about mashed potatoes that practically melt on your tongue—smooth, buttery, and infused with just the right amount of rich creaminess. But let’s be honest: standing over a stove, boiling, draining, and mashing can be a hassle, especially when you’re juggling a holiday meal or a busy weeknight dinner.
That’s where this Crockpot Mashed Potatoes Recipe comes in—zero babysitting, maximum flavor. Slow-cooked to perfection, these mashed potatoes require no boiling and no fuss.
Just toss everything into your slow cooker, let the heat work its magic, and return to a pot of velvety, restaurant-quality mashed potatoes that taste like they’ve been whipped by a pro.
These are not your average mashed potatoes—the russet potatoes cook low and slow, soaking up the buttery richness and creamy goodness of whole milk, heavy cream, and a generous knob of butter. And if you love an extra depth of flavor, adding roasted garlic takes them to the next level.
Serve them up with Crockpot Chicken Thighs for a hearty weeknight dinner or spoon them under a pile of Crockpot Steak Bites for the ultimate comfort meal. Seriously, you’ll never go back to stovetop mashed potatoes again.

Variations That Will Help You Customize!
- Brown Butter & Herb Mashed Potatoes – Instead of regular butter, melt it in a pan until golden and nutty, then stir it in with fresh sage, rosemary, or thyme for a deep, toasty flavor.
- Caramelized Onion Mashed Potatoes – Slow-cook thinly sliced onions in butter until golden brown, then fold them into the mashed potatoes for a sweet-savory depth that pairs beautifully with steak or roast chicken.
- Truffle Butter Mashed Potatoes – A drizzle of truffle oil or a small pat of truffle butter transforms this into a luxurious, restaurant-worthy side dish. Perfect for special occasions!
- Horseradish & Dijon Mashed Potatoes – If you love a little kick, add a spoonful of creamy horseradish and a dash of Dijon mustard for a tangy, slightly spicy contrast that’s incredible with beef dishes.
