Ingredients
Scale
Potatoes
- 2 ½ pounds yellow potatoes (skin on, rinsed and cut into quarters)
Dairy & Seasonings
- 3–4 tablespoons unsalted butter (plus more if needed)
- ¼–½ cup buttermilk
- 1 teaspoon kosher salt (plus more if needed)
- ½ teaspoon black pepper (plus more if needed)
- 1 tablespoon fresh rosemary, chopped
Instructions
- Prepare Potatoes: Cut the yellow potatoes into quarters with the skin on and rinse them thoroughly to remove any dirt.
- Boil Potatoes: Place the potato quarters into a large pot and add cold water, enough to completely cover them. Bring the water to a boil over high heat and cook the potatoes for about 15 minutes, or until they are fork tender.
- Drain Potatoes: Once cooked, drain the potatoes in a colander and then return them to the warm pot to remove excess moisture and prepare for mashing.
- Mash with Butter and Seasoning: Add half of the butter, along with a pinch of kosher salt and black pepper, to the potatoes. Use a potato masher or a large wooden spoon to mash the potatoes until mostly smooth.
- Add Buttermilk and Butter: Pour in ¼ cup of buttermilk and the remaining butter. Continue mashing and mixing until the potatoes reach a creamy consistency. Taste and adjust seasoning with additional buttermilk, salt, and pepper as desired.
- Finish with Rosemary: Stir in the fresh chopped rosemary for a fragrant herbaceous finish. Transfer the mashed potatoes to a serving dish and serve warm.
Notes
- Leaving the skins on adds texture and nutrients but you can peel if preferred.
- For creamier mashed potatoes, gradually add buttermilk until desired consistency is achieved.
- Fresh rosemary provides the best flavor; dried rosemary can be used but add less as it is more potent.
- This dish pairs beautifully with roasted meats, grilled vegetables, or as a hearty vegetarian main.
