Cream-baked Onions

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.

Prepare the onions

  1. Peel the onions and cover them with boiling water.

  2. Boil for 10 minutes, then drain.

  3. Cover again with boiling water, add ½ teaspoon of coarse sea salt, and cook until tender.

  4. Drain carefully and place the onions in a baking dish.

Bake and serve

  1. Top each onion with 1 teaspoon of butter, and add pepper and salt to taste.

  2. Fill the dish half full with milk and cover with a layer of fine bread crumbs.

  3. Bake at 350°F (175°C) until golden brown.

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

What each ingredient does

Onions
Become tender and sweet as they cook, forming the body of the dish.
Milk
Forms a moist, creamy liquid that surrounds the onions as they bake.
Butter
Adds richness and helps the crumbs and onions brown in the oven.
Fine bread crumbs
Form a crust on top that browns and adds a crisp contrast to the soft onions.

The step that matters

Drain carefully after cooking. Onions cooked until tender are soft and fragile, so tearing them while draining or moving them can break their layers. Handling them gently keeps each onion whole in the dish.

Swap the onion

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

  1. Capsicumfits better
  2. Potatofits better
  3. Tomatofits better
  4. Onionthe original

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