Hashed Potatoes, Browned

Ingredients

Directions

The book gives no oven temperature. The 350°F (175°C) in the steps was added when the recipe was transcribed, as a starting point.

Cook the potatoes

  1. Combine the potatoes, minced celery, grated onion, and salt in a pot.

  2. Cook until the potatoes are tender but not broken.

  3. Drain the water.

Assemble

  1. Transfer the potatoes to a buttered baking dish.

  2. Mix the hot milk with the softened butter and flour in a bowl until combined. Stir in the minced parsley.

  3. Pour the mixture over the potatoes.

  4. Cover the dish.

Bake and brown

  1. Bake at 350°F (175°C) for 15 minutes.

  2. Remove the cover.

  3. Brown the potatoes under the broiler until golden.

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

What each ingredient does

Potatoes
Form the bulk of the dish and, once cooked, soften into a tender, starchy base.
Butter
Adds richness and fat, helping the potatoes brown and carrying flavor.
All-purpose flour
Thickens the hot milk into a light sauce that coats the potatoes.
Milk
Forms the moist, creamy sauce that surrounds the potatoes during baking.

The step that matters

Drain the potatoes well before assembling. Leftover cooking water dilutes the milk and flour sauce, leaving it thin, and surface moisture slows the browning under the broiler.

Swap the onion

How well each one fits the dish's main ingredients (potato, celery, milk, butter, flour, parsley):

  1. Carrotfits better
  2. Chivefits better
  3. Leekfits better
  4. Onionthe original

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