Ingredients

Directions

Prepare and start browning

  1. Peel and chop the boiled potatoes finely.

  2. In a frying pan, heat the butter or drippings over medium heat.

  3. Add the chopped potatoes and minced onion, cooking slowly without stirring.

  4. After a few minutes, check if the potatoes are browning by lifting the edge carefully.

Brown and serve

  1. Once browned, turn the potatoes in large sections, adding more butter if needed.

  2. Season with salt and pepper, turning to brown both sides.

  3. Once browned, move the potatoes to one side of the pan, melt more butter, and turn the potatoes over to coat.

  4. Cook for a few more minutes, then serve.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs

What each ingredient does

Boiled potatoes
Provide the bulk and starch that crisp and brown into a golden crust.
Onion
Adds sweetness and savory aroma as it cooks into the potatoes.
Butter or drippings
Conducts heat and fat for browning and adds rich flavor to the crust.

The step that matters

Leave the potatoes undisturbed until a crust forms. Browning needs direct contact with hot fat and a dry surface. Stirring or turning too early prevents a crust from forming and leaves the potatoes soft and pale.

Swap the onion

How well each one fits the dish's main ingredients (potato, butter, pepper):

  1. Capsicumfits about as well
  2. Chivefits about as well
  3. Onionthe original
  4. Carrotfits about as well

Fit is the average pairing score against potato, butter, pepper. Candidates are from the same food group and used in at least 100 recipes.
