Key Ingredients Guide
- Leg of lamb: Select meat with light marbling for the best flavor
- Pistachios: Use unsalted, bright green nuts for authentic taste

Step-by-Step Instructions
- Oven and Setup:
- Heat oven to 200°C conventional heat. Let meat reach room temperature. Gather equipment and an oven-safe roasting pan.
- Vegetable Preparation:

The pistachios are essential to this recipe, creating a rich and creamy pesto. Our family discovered it pairs wonderfully with pasta and fish dishes as well.

Perfecting Your Technique
- Meat Temperature:
- Cold meat cooks unevenly. Rest lamb portions at room temperature for 30 minutes before cooking.
- Resting Period:
- Allow 5-10 minutes rest under foil after cooking for juices to redistribute.
- Proper Slicing:
- Cut perpendicular to meat grain for maximum tenderness.
