Step-by-Step Guide To Make Hairy Bikers’ Slow Cooker Liver And Onions
- Prepare the Ingredients: Begin by slicing the onions thinly and chopping the liver into slices or chunks. Mince the garlic cloves and set everything aside.
- Brown the Liver: Heat a tablespoon of butter or oil in a frying pan over medium-high heat. Once hot, add the liver slices and quickly brown them on all sides. This step helps seal in the flavor and gives the liver a nice caramelization.
- Caramelize the Onions: In the same pan, add a little more butter if needed and sauté the sliced onions over medium heat until they soften and turn golden brown. Stir frequently to prevent burning.
- Add Garlic and Flour: Once the onions are caramelized, add the minced garlic and cook for about 1 minute. Sprinkle in the flour and stir to coat the onions and garlic. This will help thicken the sauce as the dish cooks.
- Transfer to Slow Cooker: Transfer the browned liver and caramelized onion mixture to the slow cooker.
- Add the Stock and Seasonings: Pour in the beef stock, Worcestershire sauce, and thyme. Season with salt and pepper to taste. Stir to combine everything.
- Slow Cook: Cover the slow cooker and cook the liver on low for about 4-6 hours. The long, slow cooking time ensures the liver becomes tender and absorbs the flavors of the onions and stock.
- Final Adjustments: Once the liver is cooked, check the seasoning and adjust salt and pepper if needed. If the sauce is too thin, you can turn the slow cooker to high for the last 30 minutes to reduce and thicken the sauce.
- Serve: Serve the liver and onions with mashed potatoes, rice, or your favorite side dish. Enjoy the rich and tender flavors!
Mastering The Recipe: Tips And Tricks
- Choose the Right Liver: Lamb’s liver tends to be milder in flavor compared to beef liver, making it a great choice if you want a more subtle taste. Beef liver is more robust and works well if you prefer a stronger flavor.
- Do Not Overcook: Liver can become tough and dry if overcooked. The slow cooker will do the work for you, but it’s important to avoid cooking for too long. Keep an eye on the texture of the liver towards the end of cooking.
- Add a Touch of Wine: For a deeper flavor, consider adding a splash of red wine or balsamic vinegar to the sauce while it’s cooking. This adds a richness to the dish.
- Use Fresh Herbs: Fresh thyme can make a big difference in flavor, but if you only have dried, that works too. Just remember to use less, as dried herbs are more potent.
- Brown the Liver and Onions First: Browning the liver and onions before slow cooking enhances the flavor and texture of the dish. Don’t skip this step!
- Serving Suggestions: Pair the liver and onions with mashed potatoes, creamy polenta, or buttered vegetables for a well-rounded, comforting meal.

Simple Twists On Hairy Bikers’ Slow Cooker Liver And Onions Recipe

The Hairy Bikers’ Slow Cooker Liver and Onions recipe is a comforting and hearty dish, perfect for those chilly days when you crave a rich, flavorful meal. But if you’re looking to give it a fresh spin or experiment with new flavors, there are a variety of simple twists you can add to the original recipe. Whether you’re after something more decadent or you want to make the dish a bit healthier, here are a few ideas:
- Add a splash of balsamic vinegar: The sweetness of balsamic vinegar can add a delightful tangy note to the dish. Pour a little into the slow cooker just before serving, and let it meld with the onions and liver juices. This acidity can balance out the richness of the liver and elevate the overall flavor profile.
- Incorporate different herbs and spices: While the traditional recipe calls for thyme, why not experiment with other herbs? Sage, rosemary, or bay leaves can bring a unique depth of flavor to the dish. If you want a little heat, a sprinkle of chili flakes or paprika could give it an exciting twist.
- Use chicken or pork liver instead of beef: If you’re not a fan of beef liver, you can swap it out for chicken or pork liver. Chicken liver is milder and more delicate, while pork liver has a slightly sweeter flavor, making either a great alternative.
- Serve with a creamy sauce: Instead of just the onions, you can add a rich, creamy sauce to the liver. Heavy cream, crème fraîche, or even a dollop of sour cream can create a luxurious finish. Simply stir it in once the liver and onions are cooked through, allowing the sauce to thicken slightly.
- Add a few vegetables: For extra nutrition and flavor, consider adding vegetables such as carrots, celery, or bell peppers. These can cook alongside the liver and onions, absorbing all the lovely juices, making the dish even more hearty and satisfying.
- Experiment with alcohol: You could add a splash of red wine, sherry, or brandy to the slow cooker to create an aromatic depth. The alcohol will cook off, leaving behind a rich, savory essence that complements the dish perfectly.
How To Properly Store Leftovers
Liver and onions, especially when slow-cooked, tend to retain a lot of moisture, making it perfect for storing as leftovers. Proper storage is essential to maintain both the flavor and safety of the dish. Here’s how to store it correctly:
- Cool the leftovers quickly: After finishing your meal, allow the liver and onions to cool at room temperature for no more than two hours. If you’re not planning to eat them right away, it’s important to move them into the fridge quickly to prevent bacteria growth.
- Store in an airtight container: Once the dish has cooled, transfer it into an airtight container. This helps preserve the freshness of the liver and onions and prevents the absorption of any unpleasant odors from the fridge. It’s best to keep the liver and onions in the same container to retain the flavor.
- Refrigerate for up to 3 days: Liver and onions should be eaten within 2 to 3 days of cooking if stored in the refrigerator. Keep the fridge temperature at 40°F (4°C) or below to maintain the safety and quality of the food.
- Freezing for longer storage: If you want to keep the leftovers for a longer period, freezing is an option. Just ensure that you allow the dish to cool completely before freezing. Store the liver and onions in freezer-safe containers or ziplock bags, removing as much air as possible to prevent freezer burn. You can store the dish in the freezer for up to 3 months.
- Reheat carefully: When reheating, ensure that the liver and onions are heated through to 165°F (74°C) to kill any harmful bacteria. You can reheat in the microwave or on the stovetop, but be careful not to overcook the liver, as it can become tough.
What To Eat With Hairy Bikers’ Slow Cooker Liver And Onions?
The rich and savory flavors of the liver and onions call for side dishes that can either complement or balance out the richness. Here are a few ideas on what to serve with this dish:

- Buttered Greens: Steamed greens like spinach, kale, or broccoli provide a refreshing contrast to the rich liver. A little butter or olive oil with a squeeze of lemon adds flavor and brightness to the dish.
- Crusty Bread: A slice of crusty bread, toasted with a little butter or olive oil, is ideal for mopping up the gravy. You could also try a warm dinner roll for a softer, fluffier option.
- Rice or Couscous: A side of rice or couscous can be an excellent option for something lighter yet still hearty. The grains will absorb the flavorful juices from the liver and onions, making each bite delicious.
- Roast Vegetables: Roasted root vegetables, such as carrots, parsnips, or sweet potatoes, are an ideal side dish. The slight caramelization from roasting adds a natural sweetness that balances the rich, savory liver.
- Apple Sauce or Pickles: The acidity of apple sauce or pickles can cut through the richness of the liver and add a refreshing contrast. The sweetness of apples and the tang of pickles offer a perfect counterpoint to the deep flavors of the dish.
