Flank steak is a popular cut of beef known for its rich flavor and tender texture when cooked correctly. One of the best ways to cook flank steak is in a slow cooker, as it allows for even cooking and infuses the meat with a depth of flavor that’s hard to achieve with other cooking methods. However, the key to cooking flank steak in a slow cooker is to cook it for the right amount of time. In this article, we’ll explore the ideal cooking time for flank steak in a slow cooker and provide some valuable tips for achieving perfect results.
Understanding Flank Steak and Its Cooking Requirements
Before we dive into the cooking time, it’s essential to understand the characteristics of flank steak and its cooking requirements. Flank steak is a lean cut of beef, which means it has less marbling (fat) than other cuts. This makes it more prone to drying out if overcooked. Flank steak is also a relatively thin cut, which means it cooks quickly.
To cook flank steak to perfection, it’s crucial to cook it to the right internal temperature. The recommended internal temperature for flank steak is at least 135°F (57°C) for medium-rare, 145°F (63°C) for medium, and 160°F (71°C) for medium-well or well-done. However, it’s essential to note that flank steak can become tough and chewy if overcooked, so it’s better to err on the side of undercooking than overcooking.
The Role of Slow Cooking in Cooking Flank Steak
Slow cooking is an ideal method for cooking flank steak, as it allows for even cooking and helps to break down the connective tissues in the meat. Slow cooking also helps to infuse the meat with a depth of flavor that’s hard to achieve with other cooking methods.
When cooking flank steak in a slow cooker, it’s essential to cook it on low heat for an extended period. This helps to break down the connective tissues in the meat and makes it tender and flavorful. Cooking flank steak on high heat can result in a tough and chewy texture, so it’s best to avoid high heat when slow cooking.
Cooking Time for Flank Steak in a Slow Cooker
The cooking time for flank steak in a slow cooker depends on several factors, including the size and thickness of the steak, the heat setting, and the level of doneness desired. Here are some general guidelines for cooking flank steak in a slow cooker:
- Low heat: 8-10 hours for a 1-2 pound flank steak, cooked to medium-rare or medium.
- Low heat: 10-12 hours for a 1-2 pound flank steak, cooked to medium-well or well-done.
- High heat: 4-6 hours for a 1-2 pound flank steak, cooked to medium-rare or medium. (Note: Cooking on high heat is not recommended, as it can result in a tough and chewy texture.)
It’s essential to note that these are general guidelines, and the cooking time may vary depending on the specific slow cooker and the size and thickness of the steak. The best way to ensure that the steak is cooked to the right temperature is to use a meat thermometer.

What is the ideal cut of flank steak for slow cooking?
The ideal cut of flank steak for slow cooking is a lean cut, typically around 1-1.5 pounds in weight. Look for a cut that is evenly trimmed of excess fat and has a uniform thickness. This will ensure that the steak cooks evenly and is tender when finished. You can usually find flank steak at your local butcher or grocery store, and it may be labeled as “flank steak” or “London broil.”
When selecting a cut of flank steak, it’s also important to consider the level of marbling, which refers to the amount of fat that is dispersed throughout the meat. A cut with a moderate level of marbling will be more tender and flavorful than a very lean cut. However, be careful not to choose a cut that is too fatty, as this can make the steak difficult to cook evenly.
How do I prepare the flank steak for slow cooking?
To prepare the flank steak for slow cooking, start by seasoning the steak with your desired spices and herbs. You can use a dry rub or a marinade, depending on your personal preference. If using a marinade, be sure to pat the steak dry with paper towels before placing it in the slow cooker to prevent excess moisture from affecting the cooking process.
Next, heat a skillet over high heat and sear the steak for 1-2 minutes on each side. This will create a flavorful crust on the steak and help to lock in the juices. After searing the steak, place it in the slow cooker and add your desired cooking liquid, such as beef broth or wine. Make sure that the steak is covered with the liquid and then cook on low for 8-10 hours or on high for 4-6 hours.
What is the best cooking liquid to use for slow-cooked flank steak?
The best cooking liquid to use for slow-cooked flank steak is a matter of personal preference, but some popular options include beef broth, red wine, and stock. You can also use a combination of liquids, such as beef broth and red wine, to create a rich and flavorful sauce. When choosing a cooking liquid, consider the flavor profile you want to achieve and the level of acidity you prefer.
In addition to the cooking liquid, you can also add aromatics such as onions, carrots, and celery to the slow cooker to add depth and complexity to the dish. These aromatics will cook down and create a rich, flavorful sauce that complements the steak perfectly. You can also add other ingredients, such as garlic and herbs, to the cooking liquid to further enhance the flavor.
How long does it take to cook flank steak in a slow cooker?
The cooking time for flank steak in a slow cooker will depend on the size and thickness of the steak, as well as the desired level of doneness. As a general rule, a 1-1.5 pound flank steak will take 8-10 hours to cook on low or 4-6 hours to cook on high. However, it’s always best to check the steak for tenderness and cook it to your desired level of doneness.
To check the steak for doneness, use a fork to pierce the meat. If it slides in easily, the steak is tender and cooked to perfection. If not, cover the slow cooker and cook for an additional 30 minutes to 1 hour, or until the steak reaches your desired level of tenderness. It’s also important to note that flank steak can become tough if overcooked, so be careful not to overcook it.
Can I cook flank steak from frozen in a slow cooker?
Yes, you can cook flank steak from frozen in a slow cooker, but it’s not the recommended method. Cooking frozen steak can lead to uneven cooking and a less tender final product. However, if you’re short on time and need to cook a frozen steak, it’s still possible to achieve good results.
To cook a frozen flank steak in a slow cooker, simply place the steak in the slow cooker and add your desired cooking liquid and aromatics. Cook on low for 10-12 hours or on high for 6-8 hours, or until the steak reaches your desired level of tenderness. Keep in mind that cooking a frozen steak will require a longer cooking time, and the results may vary depending on the size and thickness of the steak.
How do I slice and serve slow-cooked flank steak?
To slice and serve slow-cooked flank steak, start by removing the steak from the slow cooker and letting it rest for 10-15 minutes. This will allow the juices to redistribute and the steak to retain its tenderness. Next, slice the steak against the grain, using a sharp knife to create thin, even slices.
To serve, place the sliced steak on a platter or individual plates and spoon some of the cooking liquid over the top. You can also serve the steak with your choice of sides, such as mashed potatoes, roasted vegetables, or a salad. Additionally, you can use the cooking liquid as a sauce, serving it over the steak or using it as a dipping sauce.
Can I refrigerate or freeze leftover slow-cooked flank steak?
Yes, you can refrigerate or freeze leftover slow-cooked flank steak, but it’s best to consume it within a few days for optimal flavor and texture. To refrigerate leftover steak, place it in an airtight container and store it in the refrigerator for up to 3 days. To freeze leftover steak, place it in a freezer-safe bag or container and store it in the freezer for up to 3 months.
When reheating leftover steak, it’s best to use low heat to prevent drying out the meat. You can reheat the steak in the microwave, oven, or on the stovetop, or use a slow cooker to reheat it to your desired temperature. Additionally, you can use leftover steak in a variety of dishes, such as salads, sandwiches, and stir-fries.
