Lamb gravy – the perfect finish to your roast

Don’t throw away those precious lamb roasting juices! They’re the secret to a rich and silky lamb gravy that’s surprisingly easy to make. This fail-proof recipe will complete your roast lamb dinner and leave your guests thoroughly impressed.

My favorite blush pink leg of lamb roast isn’t complete without this rich gravy. If you have more juices, double and triple this recipe and freeze some gravy for other lamb dishes. That way you can take my pan-fried lamb shoulder chops and lamb steaks to another level as well.

Ingredients
 
 

  • 1/2 cup lamb roast pan juices + 4 tablespoons for the slurry
  • 1 tbsp lamb roast fat
  • 2 tbsp flour
  • 3/4 cup stock lamb, beef, or vegetable stock
  • 1/4 tsp salt to taste
  • 1/8 tsp ground black pepper to taste

Instructions
 

  • Strain the roast pan juices through a sieve into a measuring cup. Let it sit for 2-3 minutes or until the fat on top separates from the juices below. Skim off the fat with a large spoon, reserving 1 tablespoon for the gravy (Note 1).
    1/2 cup lamb roast pan juices, 1 tbsp lamb roast fat
  • In a small saucepan, add 1 tbsp of the roast fat, 1/2 cup of the roast pan juices, and the stock. Bring it to a simmer on medium heat.
    3/4 cup stock
  • Meanwhile, combine 4 tbsp of pan juices and the flour in a small bowl to make a slurry.
    2 tbsp flour
  • Once the juices are simmering, stir in the slurry. Keep stirring until the sauce thickens and reduce the heat to low. This will take 2-3 minutes (Note 2).
  • Remove the saucepan from the heat and season the lamb gravy with salt and pepper to taste (Note 3).
    1/4 tsp salt, 1/8 tsp ground black pepper

Notes

Note 1: Don’t discard the lamb fat, aka drippings. It’s great for frying or roasting root vegetables or to get other lamb dishes under way.
Note 2: If you have lumps in the sauce, simply strain the lamb gravy with a sieve before serving.
Note 3: For a darker-colored gravy, add 1 tsp of dark soy or Worcestershire sauce before seasoning the sauce.
Storage: You can store leftover gravy in an airtight container in the fridge for up to 4 days. Alternatively, you can freeze it in one lot or smaller convenient portions for up to 3 months.

Ingredients laid out to make lamb gravy.
  • Lamb roast pan juices and fat – Scrape all bits of the bottom of the roasting pan (that’s where all the flavor is hiding) and strain the juices and fat through a sieve. Let them sit for a bit to separate.
  • StockHomemade lamb stock is best but beef or vegetable stock work well too. Keep an eye on the salt levels as some brands are very salty and you might not need to season the gravy later on.
  • Flour – I use all-purpose flour for convenience but you can also use cornstarch as a gluten-free alternative.
  • Seasoning – Keep it simple and season the gravy with salt and pepper. All the other flavors are locked in the juices.
