Today, I’m sharing one of my favorite comfort foods liver and onions with mashed potatoes. I learned this recipe while cooking with my lovely mum, Emine. It’s full of flavor, super simple, and totally satisfying. The liver is soft and rich, the onions are sweet, and the mashed potatoes? Creamy and warm just the way they should be! Add some lemon and parsley on top, and you’ve got a cozy meal that feels like home.
Method
Cook the Liver and Onions
To start, place a large shallow frying pan on medium-high heat and pour in the sunflower oil (or whichever oil you’re using). Let the oil heat up until it’s hot but not smoking. Once it’s ready, carefully add the liver pieces. You should hear a gentle sizzle that’s how you know it’s cooking properly. Stir the liver often, making sure all sides get browned evenly. This step usually takes around 5 to 6 minutes.
Next, add the thinly sliced onions right into the pan with the liver. Sprinkle the sea salt over the top and give everything a good mix. The salt helps draw out the moisture from the onions so they soften quicker. Keep cooking everything together for another 5 minutes or so. During this time, the onions will soften completely and any liquid in the pan should mostly evaporate. Once it looks nicely cooked and not watery, add the black pepper and give it one final stir. Now it’s ready to serve while still hot and juicy.
Make the Mashed Potatoes
While the liver is cooking, you can work on the mashed potatoes. Start by peeling your potatoes and cutting them into even-sized cubes (this helps them cook faster and more evenly). Place the cubes into a large saucepan, cover them with water, and add a pinch of salt. Bring the pot to a boil, then lower the heat and let the potatoes simmer for about 20 minutes or until they are soft all the way through. You can check this by poking one with a fork it should slide in easily.
Once the potatoes are soft, drain out all the water and return them to the pot. Use a masher or a fork to mash them until they’re smooth. Add olive oil or butter (depending on your taste) to give the mash a creamy texture and rich flavor. If you want it even creamier, you can stir in a small splash of warm milk.
Put it All Together
Now it’s time to plate up your meal. Spoon a generous helping of the hot liver and onions onto your plate. Next to it, add a big scoop of creamy mashed potatoes. Sprinkle fresh flat-leaf parsley over the top for color and a burst of freshness. If you like a bit of crunch and sharpness, add some thinly sliced raw onion on top. Finally, squeeze over some fresh lemon juice to brighten up the whole dish. Serve immediately and enjoy every bite!
