This simple baked potato recipe is one my grandfather brought with him from his childhood in rural Ireland, and it’s the kind of humble, hearty comfort food that never lets you down. It uses just three ingredients—potatoes, butter, and salt—but when you give them time in a hot oven, the skins turn deep, crispy brown and the insides get fluffy and steaming. It’s the kind of thing he remembered eating after long, cold days, and now I make it for my own family when we need something warm, filling, and familiar without a lot of fuss.
Serve these traditional jacket potatoes piled into a big bowl or on a warm platter so everyone can grab their own. They’re wonderful alongside a simple green salad, roasted carrots, or a pan of sautéed cabbage if you want to lean into the Irish roots. For a heartier meal, pair them with roasted chicken, grilled sausages, or a pot of beef stew so folks can spoon the juices over the fluffy potato centers. Put out extra butter and a little dish of salt on the table so everyone can finish their own potato just the way they like it.
Oven Baked 3-Ingredient Traditional Jacket PotatoesServings: 4
Ingredients
4 large floury potatoes (such as russet or Idaho), scrubbed and well dried
4 tablespoons unsalted butter, cut into small pieces, plus more to taste
1 teaspoon coarse or flaky salt, plus more for serving
Directions
Preheat your oven to 425°F (220°C). Place a heavy baking sheet or oven-safe rack in the oven while it heats so it gets good and hot. This helps the potato skins crisp up deeply, just like my grandfather remembered from home.
Scrub the potatoes well under cool water to remove any dirt, then dry them thoroughly with a clean towel. Dry skins are key to getting that dark, crispy finish instead of steaming the potatoes.
Using a fork, prick each potato 6–8 times all over. This lets steam escape as they bake and keeps them from bursting. Rub each potato with a tiny bit of water from your hands, then sprinkle them lightly with some of the salt so a bit sticks to the damp skins.
Carefully place the potatoes directly onto the hot baking sheet or rack in a single layer, leaving space between them so air can circulate. Bake for 50–65 minutes, depending on size, until the skins are deep brown and very crisp and a fork slides in easily. If you squeeze them gently with an oven mitt, they should feel soft inside but firm on the outside.
Once the potatoes are done, transfer them to a heatproof bowl or serving dish. Let them sit for 5 minutes so the steam settles a bit. This short rest helps keep the insides extra fluffy when you open them.
Using a sharp knife, carefully slice a deep cross into the top of each potato. Using clean kitchen towels or oven mitts to protect your hands, gently squeeze the ends of each potato toward the center so the fluffy white interior pops up through the cross, just like a little blossom.
While the potatoes are still very hot, tuck 1 tablespoon of butter into the opened center of each one. Let the butter melt down into all the cracks, then sprinkle the remaining salt over the tops. Toss very gently in the bowl if you like, or simply spoon the buttery, fluffy centers and crispy skins onto plates.
Serve immediately while the potatoes are piping hot, with extra butter and a pinch more salt on the table so everyone can adjust to their own taste. The contrast of the dark, crisp skins and the soft, steamy centers is what makes this old Irish-style jacket potato so comforting.
Variations & Tips
For kids or picky eaters, you can scoop some of the fluffy potato into a small bowl, mash it with extra butter and a pinch of salt, then spoon it back into the crisp shells so it feels more like mashed potatoes in a crispy cup. If you want a slightly richer version while still honoring the three main ingredients, you can use salted butter and skip extra salting at the end, or mix a tiny splash of warm milk into the centers along with the butter for a creamier texture (my grandfather sometimes did this on especially cold nights). To stretch the recipe for a crowd, bake smaller potatoes so everyone can have two; they crisp up even more and kids love the smaller size. If your oven runs hot or the skins are getting too dark before the centers are tender, lower the temperature to 400°F (200°C) and bake a little longer—slow and steady heat keeps the insides fluffy. Leftover potatoes reheat well: slice them in half the next day and warm cut-side down in a skillet until the edges are golden and crisp again, then top with a fresh pat of butter and a sprinkle of salt.
