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!

Clove Kitchen's tips

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.

This was amazing and perfect for date night! I used a rolled boneless shoulder and cooked it for longer. Really delicious and easy to throw it in.

Haven’t used lentils much but they were stunning in this delicious meal!!! Lentils were full of flavour thanks to the stock and the lamb was so tender. Followed the recipe to the tee and wouldn’t change anything about it!

I needed to use up some lamb rump and stumbled across this recipe. I adapted it quite a bit because I didn’t have all the ingredients in the house, but can report that it works really well with lamb rump, as well as dried shiitake (soaked beforehand) in place of the button mushrooms, chickpeas in place of lentils and kale instead of spinach. I scored and rendered the fat cap of the lamb rump for 10 mins on medium heat (start from a cold pan) and cooked it for 5 mins per 100g meat with the veg in the oven. I reduced the olive oil amount to a drizzle as the lamb rump is quite a fatty cut. I served the lamb with some crusty bread and garnished with toasted pine nuts and fresh parsley. Really nice recipe that was a hit even after changing the ingredients quite a bit 😅

A total crowd pleaser; I wanted to feed a large group without killing myself in a hot kitchen and this was simple, tasty and the textures were incredible. The lamb was SO soft. I served it with a crusty loaf but in the cooler months I think buttery potato mash will be my pick!
