One tray dinners are what we all wish for. This hearty lamb roast is cooked on a bed of lentils, mushrooms, and spinach and makes you feel like you know how to nourish yourself. It's a well-rounded mix of protein, fibre, vitamins, and antioxidants, plus it's really delicious and surprisingly simple to pull together.
The base goes into the oven, you sear the lamb, then nestle it on top of the lentils and cook to pink perfection!
This is a one tray roast for 2 people, using a small marinated lamb shoulder around 400-500g, available at supermarkets and butchers. Double the recipe if you're feeding four. Just keep in mind when you're scaling up this recipe, you won't need to scale up the beef stock quite as much. Start with 1.5 cups of liquid.
The big handfuls of spinach mean you don't need to make salad tonight.
Enjoy!

For marinated butterflied lamb shoulder, cooking times vary by desired doneness. For rare (internal temperature 50–55°C / 120–130°F), roast 500g portions for 20–25 minutes, then rest for 7-10 minutes. For medium (internal temperature 60–65°C / 140–150°F), roast for 30–35 minutes, then rest. For well-done (internal temperature 70°C / 160°F and above), roast for 40–45 minutes, then rest. You can use a meat thermometer to check internal temperature, and remember the lamb will continue cooking slightly during resting. These times apply to butterflied lamb, which cooks faster due to being boneless and thinner.
