These creamy, buttery slow cooker potatoes are the ultimate no-fuss holiday side. With just three ingredients and minimal prep, you can have a rich, comforting dish that everyone will love.
Ingredients
-
3 pounds russet potatoes, well-scrubbed and unpeeled, thinly sliced (about ⅛ to ¼ inch thick)
-
1 cup heavy cream
-
6 tablespoons salted butter, cut into small pieces, plus more to grease the slow cooker
Instructions
Step 1: Prepare the Slow Cooker
Lightly grease the bottom and sides of a 5- to 6-quart slow cooker with a bit of the salted butter to prevent sticking and help the edges brown.
Step 2: Slice the Potatoes
Scrub the russet potatoes thoroughly under cool running water, removing any dirt or eyes. Do not peel. Pat dry, then slice the potatoes into thin rounds, about ⅛ to ¼ inch thick, aiming for even thickness so they cook at the same rate.
Step 3: Layer the Potatoes
Arrange the unpeeled sliced potatoes in the bottom of the slow cooker in an even layer, then continue layering the remaining slices on top, loosely shingling them so there are minimal gaps. This helps them cook evenly and soak up the cream and butter.
Step 4: Add the Cream and Butter
Drizzle the heavy cream evenly over the layered potatoes, trying to cover as much surface area as possible so the cream can seep between the slices. Dot the top of the potatoes with the remaining pieces of salted butter, spacing them out so the butter melts and runs down through the layers as the potatoes cook.
Step 5: Cook
Cover the slow cooker with the lid and cook on HIGH for 3 to 4 hours, or on LOW for 6 to 7 hours, until the potatoes are very tender when pierced with a fork and the cream and butter have thickened into a rich, glossy sauce.
Step 6: Finish and Serve
Once cooked, gently stir just the top layer to coat everything in the creamy butter sauce, being careful not to mash the potatoes. Taste and, if desired, adjust seasoning at the table with a light sprinkle of salt and freshly ground black pepper. Turn the slow cooker to WARM and let the potatoes sit, covered, for 10 to 15 minutes before serving to allow the sauce to thicken slightly and cling to the potatoes. Serve straight from the slow cooker for an easy, family-style presentation.
Tips for Perfect Slow Cooker Potatoes
-
Use Russet Potatoes: Russets are ideal for this dish because they become tender and creamy as they cook. Their thin skins add texture and rustic charm.
-
Slice Evenly: Uniform slices ensure the potatoes cook at the same rate. A mandoline slicer is highly recommended for consistent thickness.
-
Do Not Peel: Leaving the skins on adds flavor, texture, and nutrients. Just be sure to scrub the potatoes well.
-
Layer Loosely: Shingle the slices with minimal gaps to allow the cream to seep through and cook the potatoes evenly.
-
Do Not Overcook: Check for doneness at the lower end of the time range. Overcooked potatoes can become mushy.
-
Let It Rest: Allowing the potatoes to rest on WARM for 10 to 15 minutes after cooking helps the sauce thicken and the flavors meld.
Variations and Additions
-
Garlic Potatoes: Add 3 to 4 cloves of minced garlic between the layers.
-
Herbed Potatoes: Add 1 teaspoon of dried thyme, rosemary, or parsley to the cream.
-
Cheesy Potatoes: Sprinkle ½ cup of shredded Parmesan or Gruyère cheese over the top during the last 30 minutes of cooking.
-
Onion Potatoes: Add thinly sliced onions between the potato layers.
-
Bacon Potatoes: Sprinkle cooked, crumbled bacon over the top before serving.
-
Spicy Version: Add a pinch of red pepper flakes or cayenne pepper.
What to Serve with Holiday Potatoes
These creamy, buttery potatoes pair beautifully with:
-
Roasted Turkey or Chicken: A classic holiday pairing.

-
Prime Rib or Roast Beef: Rich potatoes balance hearty beef.

Crusty Bread: Ideal for soaking up any extra sauce.
Storage and Reheating
-
Refrigerator: Store leftovers in an airtight container for up to 4 days.
-
Reheating: Reheat gently in the microwave or in a 350°F oven covered with foil. Add a splash of cream if needed to restore creaminess.
-
Freezer: This dish can be frozen for up to 2 months. Thaw overnight in the refrigerator before reheating.
Why This Recipe Works
This recipe succeeds because of its simplicity and the slow cooking method. The thin potato slices cook gently in the cream and butter, absorbing the rich flavors as they become tender. The natural starches from the potatoes help thicken the cream into a glossy sauce, eliminating the need for flour or other thickeners.
Leaving the skins on adds a rustic touch and prevents the potatoes from becoming too soft. Cooking low and slow ensures even cooking and allows the flavors to meld beautifully.
