Oven Baked 3-Ingredients Buttermilk Baked Potatoes

1 minute read

This simple side dish is one of those quiet family treasures passed down from my grandmother. Just potatoes, buttermilk, and butter—yet together they transform into something extraordinary: crisp golden skins with fluffy, creamy centers, nestled in a rich buttermilk sauce. It’s the kind of food that feels like a hug on a chilly March evening, perfect for those in‑between days when winter and spring trade places.

Serving Ideas

Pair with roast chicken, meatloaf, baked ham, or pan‑fried pork chops.
Add a bright green side like steamed beans, roasted broccoli, or a tangy salad.
For a cozy plate, spoon the buttermilk cream from the bottom of the dish over the potatoes and serve with crusty bread to soak up every drop.

Buttermilk Baked Potatoes (3 Ingredients)

Ingredients

Ingredient	Amount	Notes
Russet or Yukon Gold potatoes	2 lbs	Small to medium, scrubbed and dried
Buttermilk	2 cups	Full‑fat, well shaken
Unsalted butter	4 tbsp	Cut into small pieces
Kosher salt	1 tsp	Optional
Black pepper	½ tsp	Optional

Directions

Preheat Oven
Heat to 375°F (190°C). Butter or spray a 9×13‑inch glass casserole dish.
Prepare Potatoes
Scrub and dry. Leave skins on. Halve larger potatoes so they cook evenly. Arrange in a single layer, cut side down if halved.
Add Buttermilk & Butter
Pour buttermilk over potatoes until halfway to three‑quarters up their sides. Dot with butter pieces. Season with salt and pepper if desired.
Bake Covered
Cover tightly with foil. Bake 45–55 minutes, until potatoes are tender. The buttermilk will thicken and separate slightly—this is perfect.
Bake Uncovered
Remove foil. Spoon some thickened buttermilk over potatoes. Return to oven uncovered for 25–35 minutes, until skins are crisp and tops golden.
Rest & Serve
Let rest 5–10 minutes. Serve hot, spooning the creamy buttermilk sauce over each portion.
