Prep Time 15 minutes
Cook Time 1 hour 15 minutes
Total Time 1 hour 30 minutes
Course Main Course
Cuisine Hungarian
Servings 10 servings


  • 100 oz lamb (leg of lamb, lamb shoulder, lamb loin, lamb neck)
  • 25 fl oz concentrated tomato broth (you can also use tomato paste and water instead to make sauce)
  • salt and ground black pepper to taste
  • 4-5 garlic cloves or to taste (I use a whole garlic head)
  • a handful of fresh tarragon leaves or 1 tsp of dried tarragon (you can use rosemary or sage leaves instead)
  • 3.5 fl oz vegetable oil


  • remove bone from the leg of lamb and lamb shoulder if necessary, then place the meat on a tray
  • place tomato broth into a bowl
  • season the broth with salt and ground black pepper to taste
  • peel garlic cloves off, crush or mince them, then add the garlic into the broth
  • chop tarragon leaves coarsely and add them to the broth
  • pour oil into tomato broth, then mix ingredients by hand to combine well (the oil will help the marinade stick to the meat)
  • pour tomato marinade over lamb to coat it evenly on both sides
  • seal the tray with food foil and place it in the fridge overnight or for a couple of hours at least
  • remove the tray from the fridge, then remove the food foil, add some water if the marinade is too thick, and cook slow the meat at 180 C/360 F until golden, flip the meat chunks several times to cook evenly (90-120 minutes)
  • turn the heat off in the oven when the roast is very tender and wait about 20-30 minutes before serving (recommended)


Cooking Tips:
  1. Season the lamb generously with salt and black pepper before cooking to ensure that it’s well seasoned and flavorful.
  2. Rub the marinade all over the meat to infuse it with flavor and aroma.
  3. Use a large baking dish that’s big enough to submerge enough the lamb in the tomato broth. This will ensure that the meat cooks evenly and absorbs all the delicious flavors of the broth.
  4. Cover the baking dish tightly with aluminum foil to trap in the heat and moisture. This will create a tender and juicy lamb that’s bursting with flavor.
  5. Experiment with different herbs and spices to customize the flavor of the dish to your liking. Try adding fresh rosemary, thyme, or oregano for a unique twist on this classic recipe.
