1. Prep the Potatoes
Wash the potatoes thoroughly, then slice them evenly (about 1/8 to 1/4 inch thick). Uniform slices ensure all pieces cook at the same rate.
2. Layer for Even Cooking
Lightly butter the slow cooker, then layer the potato slices evenly. Slightly overlapping them helps the cream and butter coat every layer.
3. Add Cream and Butter
Pour the heavy cream over the potatoes and scatter the butter pieces across the top. As the dish cooks, these ingredients combine into a rich, glossy sauce.
4. Slow Cook to Perfection
Cover and cook:
- High: 3–4 hours
- Low: 6–7 hours
Potatoes are done when they’re fork-tender and the sauce has thickened.

5. Rest and Serve
Let the potatoes sit on the warm setting for 10–15 minutes before serving. This helps the sauce thicken and cling to the layers. Avoid overmixing to maintain their texture.

Optional Enhancements
- Fresh herbs like parsley, thyme, or chives
- A sprinkle of cheese near the end of cooking
- Thin onion slices for subtle sweetness
- A squeeze of lemon at the table for brightness
Pro Tips for Best Results
- Check for doneness about 30 minutes before the end time to prevent overcooking.
- Leaving the lid slightly open in the final stage can allow the edges to brown lightly for a bit of extra flavor.
