This is the kind of slow cooker recipe you set before the morning service and return to in the late afternoon to find potatoes so buttery and tender you’ll honestly be a little emotional about it. Thick-sliced Yukon Golds melt into layered rounds, basting in butter and just enough salt to taste like the best part of a Sunday roast, even if there is no roast. While there’s no grand origin story here, the method leans on classic Midwestern church-basement practicality: minimal ingredients, hands-off cooking, and a payoff that tastes like it took all day at the stove.
Serve these butter-drenched potato rounds straight from the slow cooker or transferred to a warm platter, spooning the pooled butter over the top. They’re wonderful alongside roasted or grilled chicken, pork chops, or a simple seared steak. For a lighter plate, pair them with a crisp green salad dressed with a sharp vinaigrette to balance the richness. They also play nicely with steamed green beans, sautéed spinach, or roasted carrots. If you have leftovers, re-crisp them in a hot skillet the next morning and top with a fried egg for an easy brunch.
Slow Cooker Sunday Butter Potato Rounds
Servings: 4

Ingredients
3 pounds Yukon Gold potatoes, scrubbed and cut into 1/2-inch-thick rounds
8 tablespoons (1 stick) unsalted butter, melted, plus more for greasing the slow cooker
1 1/2 teaspoons kosher salt, plus more to taste
Directions
Lightly grease the inside of a 4- to 6-quart slow cooker with a little softened or melted butter to prevent sticking and encourage those buttery edges.
Scrub the Yukon Gold potatoes well and pat them dry. Leave the skins on for texture and flavor. Slice into even 1/2-inch-thick rounds so they cook at the same rate and hold their shape.
In a large bowl, gently toss the potato rounds with the melted butter and kosher salt, making sure every slice is lightly coated. This step helps season the potatoes all the way through as they cook.
Layer the potato rounds in the slow cooker, overlapping them slightly in concentric circles or rows, like a rustic potato gratin. Pour any remaining butter from the bowl over the top so it can seep down between the layers.
Cover the slow cooker with the lid and cook on LOW for 6 to 7 hours, or until the potatoes are very tender when pierced with a knife and the butter is bubbling gently around the edges. Avoid lifting the lid in the first few hours to maintain steady heat.
Once the potatoes are tender and glossy with butter, taste one slice and adjust the seasoning with a pinch more salt if needed. For serving, carefully lift the potato rounds out in wide spatula-fulls and arrange on a warm, rustic platter, keeping the overlapping layers intact as much as possible.
Spoon the buttery juices that have pooled at the bottom of the slow cooker over the arranged potato rounds. Serve immediately while hot and tender, letting the butter collect beneath the potatoes on the platter for that spoonable, almost-sauce effect.
Variations & Tips
To keep the recipe firmly in its 3-ingredient lane, think of add-ons as optional flourishes rather than requirements. If you want a little color and aroma without complicating the method, sprinkle the finished potatoes with a small handful of chopped fresh herbs such as parsley, chives, or thyme before serving—this will give you that herb-flecked look you see in styled photos. For a slightly deeper flavor, you can brown the butter first: melt it in a small saucepan over medium heat until it turns golden and nutty, then toss with the potatoes as directed. If you prefer a crisper edge, transfer the cooked potato rounds to a buttered baking sheet and slide under a hot broiler for 3 to 5 minutes, just until the tops take on some golden spots, then return them to a platter and spoon the slow cooker butter over. To scale up for a larger gathering, use a larger slow cooker and increase all ingredients proportionally, keeping the same thickness of slices and allowing an extra 30 to 60 minutes on LOW if your layers are very deep. Leftovers store well in the refrigerator for up to 3 days; reheat in a covered skillet over low heat with a small spoonful of butter to revive that just-cooked tenderness.
