Frequently Asked Questions

→ Can I make the pistachio pesto ahead of time?
Definitely! Prepare the pesto up to two days before and store it in the fridge in a sealed container.
→ How can I make sure the lamb is cooked the way I like?
For medium-rare lamb, cook it for about 10 minutes. If you prefer it more cooked, leave it in for 15 minutes at 240°C.
→ Can I swap out some of the vegetables?
Absolutely! Switch them up based on what’s in season—like butternut squash instead of regular squash or spinach for kale.
→ Is this meal okay to reheat later?
Yes, but keep in mind the lamb might be a little more overdone. Reheat it slowly in the oven at 160°C for 10 minutes.
→ Can the leftovers be frozen?
You can freeze the lamb and vegetables separately, but it’s better to store the pesto in the refrigerator instead.

Instructions

Step 01

Start by warming up your oven to 200°C with conventional heat to make sure everything cooks just right.

When the veggies are ready, turn the oven up to 240°C. Gently lay the lamb slices over the roasted vegetables and cook for another 10 to 15 minutes, depending on how you like your meat done.
