How to Cook Frozen Lamb Shanks: A Comprehensive Guide

Lamb shanks are an excellent choice for a special dinner or get-together with friends and family. When properly cooked, lamb shanks can be tender, flavorful, and an impressive entrée for any meal. Many people opt for frozen lamb shanks because of their convenience and ease of preparation. Though cooking frozen meat has often been thought of as a risky option, it can actually be an effective method of cooking if done correctly.

In this comprehensive guide, we will take you through every step necessary to cook delicious and succulent lamb shanks from frozen. We’ll cover preparation, cooking methods, tips and tricks for achieving that perfect tenderness, and even some recommended side dishes.

Preparing Frozen Lamb Shanks Before Cooking

The first step in successfully preparing any frozen food is properly thawing it. This rule applies to frozen lamb shanks too; you must thaw them thoroughly before cooking to ensure even cooking throughout the meat. You have three options when it comes to thawing your frozen lamb shanks:

  1. Refrigerator thawing
  2. Cold water submersion
  3. Microwave thawing

The best recommended method is refrigerator thawing. Refrigerator thawing allows for safe and gradual thawing without running the risk of bacteria growth or spoiling the meat during the process. To do this, simply place the frozen lamb shanks on a dish or tray in the refrigerator for at least 24 hours before cooking. Ensure the meat is completely wrapped or covered to avoid any contamination from other foods in your fridge.

For the cold water submersion method, fill a large bowl with cold water and immerse the frozen lamb shanks in it until they are completely submerged. Change the water every 30 minutes to maintain a consistently safe and cold temperature. This process can take around two to three hours, depending on how thick your lamb shank is.

If time is a concern and you need to thaw in a hurry, use the microwave thawing method. To do this, place the frozen lamb shanks on a microwave-safe plate and defrost at 70% power for five minutes, flipping the meat halfway through. Repeat the process until they are fully defrosted, but be careful not to overcook them.

Once you have thawed your frozen lamb shanks, prepare them by seasoning with salt, pepper, and any other spices you like. You can also marinate your lamb shanks for added flavor and tenderness before cooking.

Methods for Cooking Frozen Lamb Shanks

Now that you’ve thawed your lamb shanks and seasoned them to taste let’s explore some of the best cooking methods for achieving a succulent dish that will impress your family or guests.

Oven Roasting

Oven roasting is one of the easiest ways to cook lamb shanks from frozen. This method produces a beautifully browned crust on the outside while maintaining tender meat on the inside. Here are some steps on how to roast lamb shanks in an oven:

  1. Preheat your oven to 375°F (190°C).
  2. Place seasoned lamb shanks in a baking pan or casserole dish large enough for all pieces.
  3. Add vegetables such as onions, carrots, and celery for added flavor.
  4. Cover the dish with foil or a lid and bake for two hours or until internal temperatures reach between 145°F-160°F (63°C-71°C).
  5. After two hours remove the cover or foil and leave in the oven for another 30 minutes to allow the lamb shanks to brown.

Pressure Cooking

Pressure cooking is a truly excellent way to cook frozen lamb shanks. This method requires less time than oven roasting but still produces flavorful and tender results. To prepare your lamb shanks with a pressure cooker, follow these steps:

  2. Add the seasoned lamb shanks and sear them on each side until brown on both sides.
  3. Add vegetables or other liquids to the pot.
  4. Bring the pressure cooker up to full pressure (15 PSI), reduce heat, and cook for 35-40 minutes.
  5. Release pressure, remove lid carefully, and ensure temperature reads between 145°F-160°F (63°C-71°C).

  3. Cover and smoke for around three – four hours.
  4. Check the internal temperature of the lamb shanks and ensure they read between145°F-160°F (63°C-71°C), then remove them carefully from the smoker.
