Slow Cooker Smashed Potato Bake is the ultimate comfort food side dish, combining fluffy baby potatoes, rich butter, melted cheese, garlic, and herbs into a hearty casserole that’s perfect for family dinners, holidays, potlucks, and weekend gatherings. This recipe takes the popular smashed potato technique and adapts it for the slow cooker, creating potatoes that are tender and flavorful before being finished with a delicious cheesy topping.
Unlike traditional roasted smashed potatoes, the slow cooker gently cooks the potatoes until they’re perfectly soft, allowing them to absorb butter and seasonings throughout the cooking process. A final bake or broil transforms the cheesy topping into a beautifully golden crust, giving you the perfect balance of creamy potatoes and crispy cheese.
Whether you’re serving roast chicken, grilled steak, pork chops, burgers, or holiday ham, Slow Cooker Smashed Potato Bake is a crowd-pleasing side dish that’s easy to prepare and guaranteed to disappear quickly.

Butter Every Layer
This keeps the potatoes moist throughout cooking.
Toast Extra Cheese
Reserve a handful of cheese for the final broil.
Add Bacon at the End
This keeps it crispy.
Double the Garlic
