Ingredients

Volumes are approximate. For baking, use a scale; Metric keeps the specified gram weights.

Instructions

  1. Heat oven to 400 F / 200 C. Prick each potato several times with a fork, rub with all oil and 1 g salt, and set on a rimmed tray without wrapping in foil. Bake 60-70 minutes until tender through the center.
  2. Let potatoes cool 10-15 minutes until safe to handle. Halve lengthwise and scoop the flesh into a bowl, leaving a roughly 5-mm wall inside every skin. Keep all eight skins; retain all removed flesh.
  3. Mash the warm flesh by hand with butter, warm milk and 2 g salt. Fold in all scallions and 40 g cheddar. Do not use a food processor.
  4. Divide the entire filling among the eight shells, mounding it gently. Top evenly with the remaining 40 g cheddar. Return to the tray and bake 20-25 minutes until hot throughout, centers reach 165 F / 74 C and the cheese is melted with lightly browned spots.
  5. Stand 5 minutes before serving one half per portion. Refrigerate leftovers within 2 hours, use within 3-4 days and reheat to 165 F / 74 C. Larger potatoes may extend the first bake beyond the 150-minute schedule.

Calculation notes & sources

ESTIMATED per serving. Brand, crop, preparation, draining, pan residue and substitutions change actual nutrition. Not laboratory analysis. Each ingredient retains its primary food description and state. All listed ingredient masses are counted; cooking moisture changes do not change the stated portion count. No generic nutrient-retention factor is invented. Calories are kcal; protein, total carbohydrate, fat and total sugar are grams. Total carbohydrate includes fiber and is not net carbohydrate. Fiber and sodium are not displayed. Equal portions or explicitly counted items define the stated recipe yield. US/Metric display changes do not change these canonical inputs. Primary-source supplements are retained per ingredient where USDA lacks a field; missing values are never silently changed to zero. All filling and skins divided into eight portions; each portion one stuffed half, not a whole potato. Contains milk. Vegetarian requires suitable cheese enzymes; Gluten-Free requires ingredient labels/cross-contact checks. All measured skin oil counted.

The first bake softens the potato flesh; the second heats the refilled shells and melts the cheddar topping. Between them, the potato is cooled enough to handle, hollowed carefully and mashed by hand. Every skin and all the flesh stay in this recipe. Four similarly sized russets become eight substantial appetizer portions, each with a soft center and a skin shell that is sturdy enough to lift from the tray.

The recipe at a glance

Twice-baked cheddar potato boats makes 8 servings, with 2 hr 30 min estimated total time. View the standalone recipe page.

Start with potatoes of similar size

A one-kilogram total does not guarantee even baking if one potato is much larger than the others. Choose four reasonably similar russets, scrub them well and dry the skins before applying the oil. The skin is part of the food and the nutrient calculation, so preparation matters. Prick the potatoes and bake them unwrapped on a tray. Foil wrapping would trap moisture against the surface and produce a different shell texture from the one intended for these boats.

Let tenderness decide when to scoop

Check the center of the largest potato before ending the first bake. It should be tender throughout, not just soft near the skin. A hard central section is difficult to mash and cannot be repaired simply by mixing in more milk. Let the potatoes cool until they can be handled safely, then halve lengthwise. Use a spoon to remove the flesh gradually, keeping a small supporting wall inside each shell. Working too quickly can tear a hot, fragile skin.

Mash while the flesh is still warm

The butter melts into warm potato, and the warmed milk helps loosen it without immediately chilling the mixture. Mash by hand just until the larger lumps break down, then fold in the scallions and the first cheese allocation. A food processor can turn potato into a sticky paste, so smoothness is not a reason to use one here. Keep the filling slightly rustic. Scrape the bowl thoroughly when stuffing so none of the measured potato or dairy is deliberately discarded.

Fill all eight shells evenly

Arrange the empty halves on the tray before dividing the filling. Spoon a little into each first, then distribute the remainder to form gentle mounds. This gives a more even serving size than completely filling one shell at a time. Split the topping cheese across all eight boats. The scallions are already mixed into the filling; there is no additional garnish allocation. The second bake should heat the centers thoroughly as well as melt the cheese visible on top.

Plan for both bakes and the cooling pause

The 150-minute schedule includes preparation, the long first bake, safe handling time, filling and the second bake. Larger or unusually dense potatoes may need longer. Give the finished boats their short stand before serving so the filling is easier to manage. One portion is one stuffed half, not a whole potato. Refrigerate leftovers promptly and reheat the centers thoroughly. Do not leave the tray at room temperature for a long interval between bakes as an informal make-ahead method.

Common questions

What if a skin tears while I scoop it?

Set the damaged half snugly against the tray or support it in a small oven-safe dish, then refill gently. Keep the torn skin with its filling rather than discarding it. Leaving the specified wall of flesh and allowing safe handling time helps prevent the problem.

Can I substitute a different potato variety?

Waxy potatoes have a different texture when mashed and may not give the same fluffy filling. This formulation and its nutrition record use raw russet flesh and skin. Another variety can require different liquid and handling, so it is not treated as an exact substitute here.
