Beef in onion sauce

Ingredients

• Beef — 1 kg
• Onion — 1.4 kg
• Lamb fat — 60 g
• Butter — 100 g
• Sugar — 1 tsp
• Soy sauce — 3 tbsp
• Garlic — 6 pcs
• Vinegar — 1 tbsp
• Fresh thyme — 4 pcs
• Bay leaf — 2 pcs
• Black pepper
• Salt

Steps

1. Slice all the onions thinly and set aside.
2. Melt the lamb fat in a large heavy pot over medium heat, add the butter and let it melt.
3. Put about half of the sliced onions into the pot with a pinch of sugar and cook over medium heat, stirring occasionally, until golden and caramelized; remove the caramelized onion and reserve.
4. Cut the beef into large chunks.
5. Arrange layers in the same pot: a layer of the remaining raw sliced onion, a layer of beef pieces, season with salt and black pepper, then spread some of the reserved caramelized onion and a little butter; repeat as needed to use the meat and onions.
6. Crush or finely chop the garlic, mix it with the soy sauce and the vinegar, then pour this mixture evenly over the layered meat and onions.
7. Tuck the thyme sprigs and bay leaves among the layers, cover the pot with a lid and cook gently over low heat until the beef is very tender and the onions have formed a saucy base.
8. Remove and discard thyme stems and bay leaves before serving; spoon the onion sauce over the meat and serve warm.
