Ingredients
Preparation
Step 1
If possible, choose a leg of young lamb. You can omit the mustard, but in that case, double the amount of vegetable oil. Use fresh or dried thyme and rosemary as you prefer.
Step 2
Peel the garlic, rinse it, and pat dry with paper towels. Slice several cloves into thin slices.
Step 3
Remove any membranes from the surface of the meat. Rinse the leg, then pat dry with a kitchen towel to remove excess moisture. Make deep cuts over the surface with a sharp thin knife and insert garlic slices into them.
Step 4
Prepare the marinade. In a deep bowl, mix mild mustard, the remaining pressed garlic, black pepper, rosemary, thyme, vegetable oil, and sugar. Squeeze in lemon juice. At this stage, add other dried seasonings if you like - nutmeg, ground paprika, dried basil, or coriander all work great.
Step 5
Mix thoroughly until the salt and sugar are fully dissolved.
Step 6
Generously coat the lamb leg with the marinade on all sides.
Step 7
Wrap the meat in plastic wrap and refrigerate for at least 1 hour (overnight is best). The longer it marinates, the richer the flavor. Before baking, remove from the fridge and let it come to room temperature.
Step 8
Wrap the meat in 2–3 layers of foil. This keeps it moist and juicy. Bake in the oven at 180-220°C (355-430°F) for 1-2 hours, depending on your oven. At the end, carefully open the foil and bake uncovered for another 10-15 minutes until golden brown. Use convection mode if available.
Step 9
Serve hot, garnished with a sprig of thyme or rosemary.
