By the time April rolls around, it will be absolutely steaming hot in Hong Kong. I wanted to take advantage of some of this cooler weather to enjoy a lovely slow roasted rosemary lamb for a family Sunday dinner.

Slow roasted rosemary lamb is the kind of dish that makes everyone ask, about every 5 minutes if you're a hungry teenager," is it done yet"? " Is it done yet"? The beautiful aromatic rosemary, garlic, caramelized onions and the lamb smell so good it is hard to wait and resist.

The lamb is so tender you can cut it with your fork. The pan juices mingle with the herbs to create a delightful broth that is perfect for a glamorous gravy.

If you prefer a simple mint sauce with your lamb, then I have just the recipe for you. Throw in a few vegetables for roasting and whip up a garden delight salad and you are in for one delightfully simple but classy meal.

Sundays are also known as "Homework Hell" days. If you are a parent, you know exactly what I am talking about. For those innocent people, that have not had the joys of having your entire Sunday turned into a homework marathon, let me take a moment to explain.

Teenagers, especially boys, love to procrastinate. They also love to work independently for about 4 weeks on a project and then come for help on the last and final hour for advisement. It is on Sundays, when they feel compelled to finally practice that speech, need math or physics help and finally get around to revising for that business exam.

It is like clock work. You want a family day or day together of family fun, well you have it all right. One full solid day of togetherness double checking assignments and watching them review their presentations and the list goes on and on...but I would not have it any other way. I love my boys!

Sundays are a great day to have minimal fuss in the kitchen with lots of glamour. This dish is so easy as the prep is less than 15 minutes and then you pop it in the oven while you have time to deal with the other things at hand, like homework hell. Let your family and friends think you slaved in the kitchen, throw a little flour on your face and pretend to look distraught.  I promise I won't tell a soul.

Rosemary Lamb with Caramelized Onion Gravy

Simple savory slow roasted aromatic rosemary lamb with glamorous gravy and a side of special mint sauce.

  • Cook: 2 hrs
  • Yields: 6 Adults or 1 Hungry Teenager


lamb - 4 pounds (I used a lamb shoulder)

olive oil - 2-3 tablespoons

steak seasoning - to taste

onions - 2 small onions (1 chopped and 1 sliced)

rosemary - several springs about 8-10 (few sprigs chopped and the rest whole)

garlic - 5-8 cloves chopped

beer - 1 can (if gluten intolerant can either skip or use about 1 cup of chicken broth or white wine if prefer)

cornstarch - 1-2 teaspoons (mixed in a little water) as needed to thicken for gravy

butter - 2 knobs

mint leaves - 1 large handful fresh

water - 2 tablespoons

apple vinegar - 2 tablespoons

sugar or sugar alternative - 1 tablespoon

salt - to taste


1Preheat oven to 220°C (430°F)

2In a greased baking pan or in your dutch oven, lay your " fresh sliced" onion on the bottom of the pan. Lay a few fresh sprigs of rosemary on top (you can substitute with dried rosemary but it is just not as good). Set aside.

3Cut thin horizontal and vertical slices into the fat covering the lamb shoulder. Coat the lamb with olive oil and sprinkle with steak seasoning, minced garlic and half of the chopped rosemary and rub into the lamb with your hands. Sear lamb quickly on all sides until a nice golden brown in a large frying pan. Remove lamb and place in a you baking pan with your bed of onions and rosemary.

5Step 4: Add onions and beer to deglaze the pan the lamb was seared in.  (Can substitute beer with a glass of white wine or gluten free lamb or chicken broth if going gluten free or diabetic friendly) Gently simmer a couple of minutes until onions are slightly softened and the beer deglazes the pan.

6Gently place your seared lamb and all the lovely onions and beer on top of the layer of fresh sliced onions and rosemary in your roasting pan or dutch oven. Place a few remaining sprigs of fresh rosemary on top. (If you want, you can add some baby potatoes and root vegetables around the lamb for a compete meal)

7 Cover your roast with aluminum foil and place in the oven to cook. Set timer for 1/2 hour.

8 A the half hour mark, remove the aluminum foil cover and reduce the oven temperature to 130°C (270°F). Baste your lamb about every 20 minutes or as needed to look like you are slaving away  in the kitchen and pour yourself a glass of wine.

9Depending on the size of your lamb, it will take between 2 to 2.5 hours or until the internal temperature is about 165 F or about 30 minutes per pound. My lamb was so tender I could cut it with a spoon.

10Take your lamb out of the oven, keep it tented to keep warm while you make your gravy and/or mint sauce. Save all that glorious pan juices to make a fantastic gravy.

12Make the caramelized onion gravy: Place your pan juices through a strainer. In a pan, add back the strained juices from the roasted lamb and add enough of a cornstarch/water mixture to slightly thicken this beautiful gravy. Add a couple of knobs of butter and season to taste. Place in a gravy container to serve with the slow roasted lamb.

13Make the mint sauce: This is not required but some like gravy and some prefer mint sauce, so this is another option. In a food processor, blend your fresh mint leaves with just a little water to get it moving. In a little sauce pan add water, sugar, salt and vinegar and cook gently just until the sugar dissolves. Turn off the burner. Let mixture completely cool and then mix in your freshly chopped mint in the sugar vinegar mixture. Serve this fresh mint sauce along with your slow roasted rosemary lamb.
