Open-faced Sandwich With Potato
About this recipe
This recipe comes from a regional cooking tradition that draws on its own pantry, technique, and culinary history. The full editorial context for this cuisine is something we're still developing; the scaling and conversion tools above work the same regardless of origin.
As a pork dish, Open-faced Sandwich With Potato works through the same fast-and-slow divide as other red meats — quick-seared chops vs slow-cooked shoulder — with the cut dictating the right cooking time and temperature.
Set your servings in the scaler above and every line of the recipe rewrites itself with smart fractions and unit promotion. Open Cook Mode to step through it hands-free with timers running.

Method
- Scrub the potatoes clean and place in a small saucepan with water and 1 tablespoon of salt. Bring to a boil and simmer the potatoes for about 10 minutes. Turn off the heat and let the potatoes stand in the water for 5 minutes. Drain the potatoes and allow to cool slightly. Remember that potatoes come in various sizes, so the cooking time may vary – if they do not easily glide off of a fork when speared and lifted out of the water, they are not done yet.
- Fry bacon slices and transfer to a dish lined with paper towels.
- Peel the red onion and slice in thin rings.
- Transfer the flour to a bowl and toss the onions in the flour. Remove onions and shake off excess flour.
- Heat the oil in a saucepan over medium heat. You can test whether the oil is hot enough by adding a small piece of onion to the saucepan. If the oil bubbles around the onion, the oil is ready.
- Transfer as many onion rings to the saucepan as can fit in one layer. Do not add too many onion rings at once.
- Fry the onions for a couple of minutes until they are golden brown. Transfer onions to a dish lined with paper towels and sprinkle with salt. Repeat the process until all onions are fried.
- Butter a slice of dark rye bread and arrange round potato slices (or, if the potatoes are very small, halved potatoes) on top. Top your open potato sandwich with a good mayonnaise, crispy fried onions, fried bacon and sliced chives.
Cooking notes
When scaling protein-led dishes, weigh the meat rather than counting pieces, and remember that the pan size limits how much you can sear at once.
For volume-to-weight conversions of any ingredient — flour, sugar, butter, salts — use the ingredient converter. To translate the recipe's oven temperature between °C, °F and gas mark, see the temperature converter.
When you scale this recipe up or down, remember that cooking time does not scale linearly. A doubled cake takes longer, but not twice as long; a doubled soup takes roughly twice as long. The cooking-time guide gives sensible starting estimates by dish geometry.
Scaling notes
Scaling Open-faced Sandwich With Potato
Open-faced Sandwich With Potato is written for around four servings as it stands on this page — scaling it up for a party or down for a meal-for-one is the small math problem most home cooks face every week. Here's how this particular dish responds to scaling, what changes linearly, and what doesn't.
Pork shares scaling rules with beef — braising time is collagen-driven and mass-independent, while quick-cook methods like searing scale by the piece. Open-faced Sandwich With Potato benefits from weight-based ingredient measurement when scaled up: pork roasts in particular vary significantly in actual yield, and a recipe written for "2 lb shoulder" can mean anything from 800 g to 1.1 kg of cooked meat.
When you scale the flour in this recipe, weigh it in grams if you can — a cup of flour can weigh anywhere from 113 g to 150 g depending on how you measure. The ScaleRecipe ingredient converter uses the King Arthur Baking reference of 120 g/cup for all-purpose flour, which is the same standard most modern baking books assume.

Beyond the recipe
Substitutions & make-ahead — Open-faced Sandwich With Potato
Two things home cooks ask about most when they're outside the recipe's exact assumptions: what swaps work for which ingredients, and how the dish behaves when you make it ahead. Both depend on what Open-faced Sandwich With Potato is doing structurally — here's the practical version.
Substitution ideas
All-purpose flour
For gluten-free, a 1-to-1 gluten-free baking blend (one that contains xanthan gum) is the most reliable swap. For texture variations: bread flour gives chewier results; cake flour gives more tender. Avoid almond or oat flour as a 1:1 swap — they don't form gluten and most recipes structurally depend on it.
Bacon
For the smoky-savoury layer: ½ tsp smoked paprika + 1 tbsp olive oil approximates the bacon backbone in soups and stews. For texture, pancetta, smoked turkey, or a quality vegan bacon brand. Maillard browning is the hardest to fake — no fat-free option matches the crisp.
For weight-based swaps and arbitrary quantities, the ingredient density converter and the cup-to-grams chart cover most pantry staples.
Make-ahead and storage
Pork shoulder and slow-cooked pork dishes (Open-faced Sandwich With Potato included if it falls in that family) improve overnight as the fat redistributes and flavours integrate. Cured pork — bacon, ham, sausage — keeps well refrigerated but loses its crisp edges in storage; re-crisp in a hot skillet or under the broiler. Quick-cooked pork chops are best served the day they're cooked; the meat tightens and dries through the refrigerate-and-reheat cycle.

OpenCooking time
The cube-root rule for scaling up, the differences between meat / cake / soup geometry, and sensible starting estimates.
OpenPan size
9-inch round vs 8-inch square vs 13×9. The math is surface area, not diameter — and the converter shows you both.
