London Broil is a classic dish that is loved by many for its tender and flavorful meat. Traditionally, London Broil is prepared by marinating and grilling a beef flank steak. However, if you don’t have access to a grill or simply prefer a hassle-free cooking method, using a slow cooker is the perfect alternative. Slow cooking allows the meat to become tender and juicy, resulting in a delicious meal that will leave you wanting more.

One of the great things about cooking London Broil in a slow cooker is that it requires minimal effort. Simply season the meat, place it in the slow cooker, and let it cook for several hours.

To achieve maximum flavor, it’s important to season the London Broil before cooking. You can use a simple mixture of salt, pepper, garlic powder, and onion powder, or get creative with your seasonings. Once the meat is seasoned, place it in the slow cooker and add any additional ingredients you desire, such as onions, carrots, or potatoes. The slow cooker will work its magic, infusing the meat with all the flavors and creating a delicious broth.

Before serving, it’s important to let the London Broil rest for a few minutes. This allows the juices to redistribute throughout the meat, ensuring a moist and flavorful result. Once rested, slice the London Broil against the grain to ensure tenderness. Serve with your favorite side dishes, such as roasted vegetables or creamy mashed potatoes, and enjoy a restaurant-quality meal in the comfort of your own home.

Marinating the London Broil

Marinating the London Broil is an important step to ensure that the meat remains tender and flavorful. The marinade helps to break down the proteins in the meat, making it more tender, while also infusing the flavors into the beef.

To marinate the London Broil, you will need a marinade of your choice. Some popular options include a combination of soy sauce, garlic, Worcestershire sauce, olive oil, and various herbs and spices. You can also use pre-made marinades available at your local grocery store.

To marinate the London Broil, place the meat in a large zip-top bag and pour the marinade over it. Seal the bag tightly and massage the marinade into the meat, ensuring that it is evenly coated. Place the bag in the refrigerator and let the London Broil marinate for at least 4 hours, but preferably overnight for optimal flavor.

Setting up the Slow Cooker

Before starting to cook your London broil in a slow cooker, it is important to properly set up the appliance. Follow these steps to ensure a successful cooking process:

1. Clean the Slow Cooker

Before using the slow cooker, make sure it is clean and free from any residue or food particles. Wash the inner pot, lid, and other removable parts with warm soapy water. Rinse thoroughly and dry them completely before placing them back into the slow cooker.

2. Choose the Right Size

Ensure that the slow cooker you are using is large enough to accommodate the London broil cut of meat. It should allow for proper circulation of heat and fit comfortably without overcrowding. A 6-quart slow cooker is usually a good size for cooking a London broil.

3. Place the Slow Cooker

Find a suitable location for your slow cooker. It should be placed on a stable and heat-resistant surface, away from any flammable materials. The slow cooker should also be positioned in such a way that the lid can be easily opened without any obstructions.

4. Use the Slow Cooker Liner (Optional)

Consider using a slow cooker liner to simplify the cleaning process. The liner should be placed inside the inner pot, forming a barrier between the food and the pot. It helps to prevent sticking and makes cleanup a breeze. However, if you prefer not to use a liner, greasing the inner pot with cooking spray can also help prevent sticking.

5. Adjust the Temperature

Depending on the recipe you are following, adjust the temperature setting on your slow cooker. Most London broil recipes require low heat for a long duration, such as 8 hours on low or 4-6 hours on high. Make sure to read the recipe instructions carefully and set the slow cooker accordingly.

Following these steps will ensure that your slow cooker is properly set up and ready to cook a delicious London broil.
