Why This Works for Intermittent Fasting

Beef liver is one of the most nutrient-dense foods you can eat — loaded with zinc, iron, vitamin B12, selenium, copper, and folate in forms the body absorbs easily.

Why This Works for Intermittent Fasting

Beef liver is one of the most nutrient-dense foods you can eat — loaded with zinc, iron, vitamin B12, selenium, copper, and folate in forms the body absorbs easily. Paired with crispy bacon for fat and flavour, and sweet caramelised onions for depth, this dish delivers a high-protein, high-fat meal that sustains satiety for hours without a blood sugar spike. It works perfectly as an OMAD plate or as the main meal within a short 4–6 hour eating window.

Ingredients

  • 400g beef liver, sliced about 1 cm thick
  • 4 rashers of bacon, cut into pieces
  • 1 medium onion, halved and thinly sliced
  • 2 tbsp butter or ghee
  • 1 tsp sea salt
  • ½ tsp black pepper
  • ½ tsp smoked paprika
  • Fresh parsley, chopped (optional, to serve)

Instructions

  1. Pat the liver slices dry with paper towel. Season both sides with sea salt, black pepper, and smoked paprika.
  2. Heat a large cast iron or heavy-bottomed skillet over medium heat. Add the bacon pieces and cook until crispy, about 5–6 minutes. Remove with a slotted spoon and set aside. Leave the bacon fat in the pan.
  3. Reduce the heat to medium-low. Add the sliced onion to the bacon fat. Cook, stirring occasionally, for 10–12 minutes until completely softened and caramelised — they should be golden and sweet. Remove and set aside with the bacon.
  4. Raise the heat to high. Add the butter to the pan. When it foams and the foam begins to subside, add the liver slices in a single layer without overlapping.
  5. Sear for 2–3 minutes on the first side without moving them. Flip and cook for another 2 minutes. The liver should be deep brown on the outside and just barely pink in the centre — not raw, but not grey all the way through. Overcooking is the most common mistake; it makes liver tough and bitter.
  6. Plate the liver immediately and top with the caramelised onions and crispy bacon. Scatter parsley over the top if using. Serve at once.

Fasting Compatibility

This meal is ideal for 16:8, 18:6, OMAD, and any protocol where the eating window opens at lunch or dinner. The high protein and fat content make it an excellent first meal after a long fast — it satisfies completely without triggering the insulin spike and subsequent hunger crash that come from carbohydrate-heavy meals. The zinc and B vitamins in liver also support energy and cognitive function, which can dip after extended fasting.
