Additional Ingredients

  • Fresh Thyme - 1 tsp
  • Rapeseed oil - 1 tbsp
  • Sea salt & pepper - To taste
  • Plain flour (seasoned with salt & black pepper) - 2 tbsp
  • Worcestershire sauce - 1 tsp
  • Fresh parsley - chopped (to finish)

Method

Step 1 - Prepare the liver

Pat the liver dry with kitchen paper. Trim away any visible membranes and cut into even slices if needed. Lightly coat in the seasoned flour, shaking off the excess. That light dusting gives you flavour and helps thicken the gravy.

Step 2 - Soften the onions

Heat the butter and oil in a large frying pan over medium heat. Add the sliced onions with a pinch of salt and cook gently for 10–12 minutes until soft, golden and slightly caramelised. Remove from the pan and set aside.

Step 3 - Cook the liver

Turn the heat up slightly. Add the floured liver to the same pan. Cook for 2–3 minutes on each side. No more. Overcook it and it’ll turn tough — we want it tender, blushing in the centre.

Step 4 - Build the gravy

Return the onions to the pan. Add thyme and Worcestershire sauce. Pour in the beef stock and gently simmer for 5–7 minutes until the gravy thickens and coats everything beautifully.

Taste. Adjust seasoning. Be bold with it.

Step 5 - Finish strong

Scatter over fresh parsley and serve immediately.

Frequently Asked Questions

  • Cook liver quickly over a high heat and avoid overcooking it. It should be seared on the outside but still tender inside. Cooking it for too long makes it firm and dry.

  • Some people soak liver briefly in milk before cooking to mellow the flavour. It’s optional, but it can help if you prefer a milder taste.

  • Use the pan juices from cooking the liver and onions. Build the gravy in the same pan so it captures all the flavour, stirring until thick and glossy.

  • Liver cooks quickly — usually just a few minutes per side depending on thickness. It should be browned outside and tender when sliced.

  • Creamy mashed potatoes, seasonal greens and crusty bread are traditional sides. They help soak up the rich gravy and balance the flavour of the liver.
