Herb-Crusted Roast Lamb with Garlic Jus Recipe FAQs
How do I know if my lamb leg is fresh and suitable for this recipe?

Can I store the leftover roast lamb and garlic jus together?
It’s best to store the lamb and garlic jus separately. Keep the lamb in an airtight container in the fridge for up to 3 days. Store the garlic jus in a sealed jar or container for up to 1 week in the fridge to maintain its fresh, vibrant flavor.
What is the best way to freeze this herb-crusted roast lamb?

Why did my crust not crisp properly during roasting?
This can happen if the herb mixture is too wet or the oven temperature was too low. Ensure you press the herb crust firmly onto the lamb and start roasting at a higher temperature (400°F) to set the crust before lowering the heat to cook through. Also, lightly pat the lamb dry before applying the crust to avoid sogginess.
Is this recipe safe for pets to eat?
While lamb meat itself can be pet-friendly, the herb crust contains garlic, which is toxic to dogs and cats. Always avoid sharing any herb-crusted pieces or garlic jus with your pets. Cook plain lamb separately if you want to treat your furry friends safely.
