To Make Sage and Onion Sauce
Ingredients
Directions
Prepare
Chop the sage leaves finely until you have ½ tablespoon.
Chop the onion very finely until you have 1 tablespoon.
Make the sauce
In a saucepan, simmer the sage and onion in 4 tablespoons of water for 10 minutes.
Add the black pepper, coarse sea salt, and grated bread crumbs, mixing well.
Pour in ¼ pint of thin melted butter or gravy and let the sauce simmer for a few minutes, stirring constantly.
Serve hot in a sauce tureen.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Fresh sage leaves
- Provides the main herbal aroma that defines the sauce.
- Onion
- Adds savoury sweetness and aromatic depth as it softens in the water.
- Grated bread crumbs
- Thicken the sauce and give it body as they absorb the liquid.
- Thin melted butter or gravy
- Supplies fat or savoury liquid, giving the sauce richness and moisture.
The step that matters
Stirring while the sauce simmers. Bread crumbs can settle and scorch on the bottom of the pan or clump when they hit hot liquid. Constant stirring keeps them dispersed, so the sauce thickens smoothly and does not burn.
Swap the onion
