- 2 tablespoons butter, melted
Optional (not included in the 3 ingredients):
- Pinch of salt
- Pinch of black pepper
Instructions
1. Preheat the Oven
Set your oven to 200ยฐC (400ยฐF). Lightly grease a baking dish or line it with parchment paper.
2. Prepare the Potatoes
Wash the potatoes thoroughly and dry them well. Use a fork to pierce each potato several timesโthis helps release steam while baking.
3. First Bake
Place the potatoes in the baking dish and bake for 35โ40 minutes, until they start to soften but are not fully cooked.
4. Add the Buttermilk Mixture
Remove the potatoes from the oven carefully. Cut a slit across the top of each one and gently press the sides to open them slightly.
Pour the buttermilk evenly over the potatoes, letting it soak inside. Drizzle the melted butter over the top.
5. Finish Baking
Return the potatoes to the oven and bake for an additional 10โ15 minutes, until fully tender and lightly golden on top.
6. Serve
Allow the potatoes to cool slightly before serving. Add salt and pepper if desired.
