Directions
- Preheat your oven to 375°F (190°C). Lightly butter or spray a 9×13-inch glass casserole dish.
- Scrub and dry the potatoes completely. Leave skins on. For larger potatoes, cut in half lengthwise for even cooking.
- Arrange potatoes in a single layer in the casserole dish. Halved potatoes should be cut side down.
- Pour the buttermilk over the potatoes until it reaches halfway to three-quarters up the sides.
- Dot with butter pieces, sprinkle with salt and pepper if desired.
- Cover tightly with foil and bake 45–55 minutes until tender.
- Remove foil, spoon some thickened buttermilk over the potatoes, and bake uncovered 25–35 minutes until skins are golden and crisp.
- Let rest 5–10 minutes before serving. Spoon creamy buttermilk sauce over each serving.
Tips & Variations
- For extra crispy skins, prick potatoes with a fork and rub with butter before baking.
- Swap ½ cup buttermilk for heavy cream for richer, creamier potatoes.
- For picky eaters, peel potatoes for an all-soft texture.
- Make ahead: assemble dish up to the buttermilk step and refrigerate up to 8 hours. Add 5–10 minutes to bake time.
- Leftovers reheat beautifully or mash with thickened buttermilk for next-day mashed potatoes.
Pairing Ideas

- Add steamed green beans, roasted broccoli, or a fresh salad to balance richness.
