Calf's Liver
Ingredients
Directions
Prepare
Bring salted water to a boil, add the liver for 5 minutes, then drain.
In a bowl, combine sweet oil, bay leaf, thyme, parsley, green onion, salt, and pepper.
Add the liver to the mixture, cover, and marinate for 4 to 6 hours, turning occasionally.
Roast over a fire
Wrap the liver in buttered paper and roast over a fire, basting with oil from the marinate.
Remove the paper a few minutes before done, baste with drippings, and serve with gravy.
Sauté and serve
For sautéing, melt butter in a pan, add parsley and green onions, then the liver slices.
Sprinkle with flour, add warm broth, claret wine, salt, pepper, and allspice, and cook for 10 to 12 minutes.
For oven cooking, fry liver in butter for 5 minutes, season, and serve warm.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Calf's liver
- Provides the main protein and tender texture that the dish is built around.
- Sweet oil
- Carries the herbs and seasonings into the liver and keeps its surface moist while roasting.
- Butter
- Adds richness and helps the liver brown and taste savoury when fried.
- Flour (in the method)
- Thickens the pan juices into a light sauce that coats the liver.
- Claret wine
- Adds acidity and depth to the pan sauce, balancing the richness of the liver.
The step that matters
Boil the liver for only 5 minutes before marinating. Liver turns grainy and tough when overcooked, because its proteins tighten with prolonged heat. A short blanch firms the surface so it can be handled, while leaving the inside tender for the later cooking.
Swap the onion
How well each one fits the dish's main ingredients (liver, thyme, parsley, pepper, butter, wine, allspice):
- Shallotfits better
- Carrotfits better
- Parsnipfits better
- Onionthe original
Fit is the average pairing score against liver, thyme, parsley, pepper, butter, wine, allspice. Candidates are from the same food group and used in at least 100 recipes.
