Melt the butter in a skillet.
Sauté the spinach for a few minutes.
Soak the bread in ½ cup of milk.
Add the soaked bread to the spinach.
Make the custard
Beat the eggs in a bowl.
Add 2 cups of milk to the eggs.
Beat the egg whites separately.
Fold the beaten egg whites into the mixture.
Add salt to taste.
Pour the mixture into a baking dish.
Bake
Bake at 350°F (175°C) for 30 minutes.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Eggs
- Set the mixture into a structure and add richness when baked.
- Bread
- Soaks up milk and gives the dish body and a soft, custardy crumb.
- Milk
- Adds moisture and softens the mixture as it bakes.
- Spinach
- Provides the main filling, adding flavour, moisture and a green colour.
- Butter
- Adds fat and flavour to the spinach as it cooks in the skillet.
The step that matters
Folding in the beaten egg whites. Egg whites hold air when beaten, and folding gently keeps that air in the mixture so the dish rises and stays light; stirring hard would deflate it.
Swap the spinach
How well each one fits the dish's main ingredients (butter, bread, milk, egg):
- Potatofits better
- Asparagusfits better
- Leekfits better
- Spinachthe original
Fit is the average pairing score against butter, bread, milk, egg. Candidates are from the same food group and used in at least 100 recipes.
