The question of whether you can pressure cook frozen London broil is a common one, and the answer is a resounding yes! The beauty of pressure cooking lies in its ability to transform even the most stubbornly frozen cuts of meat into tender, flavorful meals in a fraction of the time it would take using traditional methods. However, there are some important considerations to keep in mind to ensure a safe and delicious outcome. This comprehensive guide will walk you through everything you need to know about pressure cooking frozen London broil, from preparation to cooking times to achieving that perfect level of tenderness.
Understanding London Broil and Pressure Cooking
Before we dive into the specifics, let’s establish a clear understanding of London broil and the principles of pressure cooking. London broil isn’t actually a specific cut of meat, but rather a method of preparing and cooking a relatively tough cut, typically flank steak or top round steak. The name likely originated in North America and implies a style of cooking involving marinating, broiling, and then slicing thinly against the grain.
Pressure cooking, on the other hand, uses a sealed pot to trap steam, which significantly raises the internal temperature and pressure. This accelerated cooking process is ideal for tough cuts of meat because it breaks down connective tissues, resulting in a more tender product.
The Advantages of Pressure Cooking Frozen London Broil
Pressure cooking frozen London broil offers several advantages compared to other cooking methods:
Speed: This is the most obvious benefit. A frozen London broil can take hours to thaw and cook using traditional methods. Pressure cooking slashes that time dramatically.
Tenderization: The high pressure and steam work wonders on tougher cuts like flank steak and top round, resulting in a noticeably more tender final product.
Flavor Infusion: The sealed environment of a pressure cooker allows flavors from marinades and seasonings to penetrate the meat more deeply.
Convenience: You can skip the thawing process altogether, making it a perfect option for busy weeknights when you’ve forgotten to take meat out of the freezer.
Safe Handling and Preparation
While pressure cooking frozen London broil is convenient, food safety remains paramount. Here’s how to handle and prepare your meat safely:
Choosing the Right London Broil
Select a London broil that is properly packaged and shows no signs of freezer burn. Freezer burn can affect the texture and flavor of the meat. Look for a package that is tightly sealed and has minimal ice crystals.
Is It Safe to Pressure Cook Frozen Meat?
According to food safety experts, it is generally safe to pressure cook frozen meat. The key is to ensure that the meat reaches a safe internal temperature to kill any harmful bacteria. Pressure cookers reach temperatures high enough to do this effectively, even when starting with frozen meat. However, it’s crucial to increase the cooking time to compensate for the frozen state.
Pre-Cooking Preparations
Although you’re skipping the thawing process, there are still a few things you can do to prepare your frozen London broil:
- Rinse: Briefly rinse the frozen London broil under cold water to remove any ice crystals or loose debris.
- Trim Excess Fat: If there is a significant amount of fat, you can trim some of it off while the meat is still frozen. It’s easier to trim frozen fat than thawed fat.
- Consider a Marinade: While you can add a marinade directly to the pressure cooker, it’s more effective to marinate the London broil before freezing if you plan on pressure cooking it from frozen regularly. The flavors will penetrate the meat more deeply during the freezing process. If you didn’t marinate beforehand, you can still add a flavorful liquid to the pressure cooker.
Cooking Time and Temperature Guidelines
Determining the correct cooking time is crucial for achieving a perfectly cooked London broil. Overcooking will result in dry, tough meat, while undercooking poses a food safety risk.
Adjusting for Frozen State
The general rule of thumb is to increase the cooking time by approximately 50% when cooking frozen meat in a pressure cooker compared to fresh or thawed meat. For London broil, this typically means adding 10-15 minutes to the recommended cooking time.
Suggested Cooking Times
Keep in mind that these are general guidelines, and cooking times may vary depending on the thickness of your London broil and the specific model of your pressure cooker. It’s always best to err on the side of caution and use a meat thermometer to ensure the meat reaches a safe internal temperature.
- For a 1-inch thick frozen London broil: 25-30 minutes at high pressure, followed by a natural pressure release of 10 minutes.
- For a 1.5-inch thick frozen London broil: 30-35 minutes at high pressure, followed by a natural pressure release of 10 minutes.
- For a 2-inch thick frozen London broil: 35-40 minutes at high pressure, followed by a natural pressure release of 10 minutes.
Internal Temperature
The USDA recommends a minimum internal temperature of 145°F (63°C) for beef, followed by a 3-minute rest time. Use a meat thermometer to check the internal temperature at the thickest part of the London broil after pressure cooking.
Step-by-Step Pressure Cooking Instructions
Follow these steps for perfectly pressure-cooked frozen London broil:
- Prepare the London Broil: Rinse the frozen London broil under cold water and trim any excess fat.
- Add Liquid to the Pressure Cooker: Pour about 1 cup of beef broth, water, or a flavorful marinade into the pressure cooker. This liquid is necessary to create steam.

Roasting a frozen London broil can take hours, while pressure cooking can achieve similar results in a fraction of the time. This is especially beneficial for busy weeknights when time is limited.
Secondly, pressure cooking helps retain moisture. The sealed environment traps the meat’s natural juices, preventing it from drying out during cooking. This results in a more tender and flavorful London broil, even when starting from a frozen state. It’s a convenient and effective way to prepare this cut of meat quickly and easily.
How do I adjust the pressure cooking time for a frozen London broil?
When pressure cooking a frozen London broil, you’ll need to increase the cooking time by approximately 50% compared to cooking a thawed London broil. As a general guideline, a thawed London broil might take 5-7 minutes per pound at high pressure. Therefore, a frozen London broil would require approximately 7.5-10.5 minutes per pound at high pressure.
This is just an estimate, and the exact time will depend on the thickness of the cut and the power of your pressure cooker. Always use a meat thermometer to ensure the internal temperature reaches 130-135°F for medium-rare or 140-145°F for medium. Remember that carryover cooking will also increase the temperature slightly after the pressure is released.
What liquids should I use when pressure cooking frozen London broil?
The best liquids to use when pressure cooking a frozen London broil are those that will add flavor and moisture to the meat. Beef broth is a great choice as it complements the beef flavor. You can also use water, but adding beef bouillon or Worcestershire sauce can enhance the taste. Red wine can also be used in combination with broth for a richer flavor profile.
Ensure you have enough liquid in the pressure cooker to meet the manufacturer’s minimum requirement, usually about 1 cup. The liquid is essential for creating the steam that builds pressure and cooks the meat. Experiment with different combinations to find your favorite flavor profile but always ensure safety guidelines are followed.
Can I add vegetables to the pressure cooker when cooking frozen London broil?
Yes, you can absolutely add vegetables to the pressure cooker when cooking frozen London broil. However, keep in mind that vegetables cook much faster than the meat, so you’ll need to add them strategically to avoid overcooking. Hearty vegetables like potatoes, carrots, and onions can be added closer to the beginning of the cooking process.
More delicate vegetables like broccoli or green beans should be added during a quick pressure release, or after the meat is cooked, and allowed to steam in the residual heat. This will ensure they are cooked through but not mushy. It’s all about timing and understanding how quickly different vegetables cook under pressure.
What’s the best way to release the pressure after cooking a frozen London broil?
There are two main methods for releasing pressure: natural pressure release (NPR) and quick pressure release (QPR). For a frozen London broil, NPR is generally recommended. This allows the meat to rest and continue cooking gently in the residual heat, resulting in a more tender final product. It also helps prevent the meat from seizing up due to a sudden change in pressure.
However, if you’re in a hurry, you can use QPR. Be extremely cautious as hot steam will be released rapidly. If you used NPR and the meat isn’t quite done, you can reseal the cooker and pressure cook for a few more minutes. Ultimately, the best method depends on your time constraints and desired level of tenderness.
How do I ensure my frozen London broil doesn’t come out tough when pressure cooked?
To prevent your frozen London broil from becoming tough when pressure cooked, ensure you don’t overcook it. Using a meat thermometer is crucial to achieving the desired level of doneness. Aim for an internal temperature of 130-135°F for medium-rare, as the meat will continue to cook slightly after the pressure is released.
Also, consider marinating the London broil before freezing. A marinade with acidic ingredients like vinegar or lemon juice can help tenderize the meat and add flavor. After cooking, always let the meat rest for at least 10 minutes before slicing against the grain to further improve tenderness. These steps will significantly improve the texture and flavor of your pressure-cooked frozen London broil.
