Flank steak, a staple in many cuisines, is notorious for its toughness and chewiness. However, with the right techniques and a bit of patience, this affordable and flavorful cut of beef can be transformed into a tender and mouth-watering dish. In this article, we will delve into the world of tenderizing tough flank steak, exploring the science behind its toughness, and providing you with a range of methods to soften it to perfection.
Understanding the Anatomy of Flank Steak
Before we dive into the tenderizing techniques, it’s essential to understand the anatomy of flank steak. Flank steak comes from the belly of the cow, specifically from the abdominal muscles. This area is comprised of strong, lean muscles that are designed for movement, which makes them naturally tough. The muscle fibers in flank steak are long and dense, making it challenging to break them down.
The Role of Connective Tissue
Connective tissue, particularly collagen, plays a significant role in the toughness of flank steak. Collagen is a type of protein that forms a network of fibers throughout the meat, providing structure and elasticity. However, when cooked, collagen can become rigid and tough, making the meat chewy. To tenderize flank steak, it’s crucial to break down this connective tissue.
Tenderizing Techniques: A Comprehensive Approach
Tenderizing flank steak requires a combination of techniques that target the muscle fibers and connective tissue. Here are some of the most effective methods to soften tough flank steak:
1. Mechanical Tenderization
Mechanical tenderization involves using tools or techniques to physically break down the muscle fibers and connective tissue. Some common methods include:
- Pounding: Using a meat mallet or rolling pin to pound the steak, breaking down the fibers and increasing the surface area.
- Slicing: Cutting the steak against the grain, using a sharp knife to slice through the fibers and reduce their length.
- Jaccarding: Using a jaccard meat tenderizer, a tool with small blades that pierce the meat, breaking down the fibers and connective tissue.
2. Enzymatic Tenderization
Enzymatic tenderization involves using enzymes to break down the proteins and connective tissue in the meat. Some common methods include:
- Marinating: Soaking the steak in a marinade containing enzymes such as papain (from papaya) or bromelain (from pineapple), which break down the proteins and connective tissue.
- Using tenderizing enzymes: Applying products containing enzymes such as ficin (from figs) or aspergillopepsin (from fungi) directly to the meat.
3. Thermal Tenderization
Thermal tenderization involves using heat to break down the connective tissue and muscle fibers. Some common methods include:
- Cooking low and slow: Cooking the steak at a low temperature (around 150°F – 200°F) for an extended period, allowing the connective tissue to break down and the meat to become tender.
- Braising: Cooking the steak in liquid (such as stock or wine) on low heat, allowing the connective tissue to break down and the meat to absorb flavors.
4. Chemical Tenderization
Chemical tenderization involves using acidic ingredients to break down the proteins and connective tissue in the meat. Some common methods include:
- Using acidic marinades: Soaking the steak in a marinade containing acidic ingredients such as vinegar, lemon juice, or wine, which help to break down the proteins and connective tissue.
- Adding acidic ingredients: Incorporating acidic ingredients such as tomatoes or citrus into the cooking liquid, which help to break down the connective tissue and tenderize the meat.
Additional Tips for Tenderizing Flank Steak
In addition to the techniques mentioned above, here are some additional tips to help you tenderize flank steak:
- Choose the right cut: Opt for a flank steak that is labeled as “tender” or “lean,” as these tend to be less tough than others.
- Aging the steak: Allowing the steak to age in the refrigerator for a few days can help to break down the connective tissue and tenderize the meat.
- Not overcooking: Cooking the steak to the recommended internal temperature (around 130°F – 135°F for medium-rare) can help to prevent it from becoming tough and chewy.
- Using a meat thermometer: Ensuring that the steak is cooked to a safe internal temperature can help to prevent foodborne illness.

What is flank steak, and why is it often tough?
Flank steak is a type of beef cut that comes from the abdominal muscles of the cow. It is a lean cut of meat, which means it has less marbling (fat) than other cuts. While this makes it a popular choice for those looking for a healthier option, it also means that it can be tougher and more prone to drying out if not cooked properly. The reason flank steak is often tough is that the muscles in this area are used for movement, making the meat more dense and chewy.
However, with the right techniques and cooking methods, flank steak can be tenderized and become a delicious and flavorful addition to any meal. This is why it’s essential to understand the different methods for tenderizing flank steak, which can range from simple techniques like marinating and pounding to more complex methods like braising and slow cooking.
What are the benefits of tenderizing flank steak?
Tenderizing flank steak can make a significant difference in its texture and overall flavor. When flank steak is tenderized, it becomes more palatable and easier to chew, making it a more enjoyable dining experience. Additionally, tenderizing flank steak can help to break down the connective tissues in the meat, which can make it more prone to absorbing flavors and seasonings.
By tenderizing flank steak, you can also reduce the risk of it becoming tough and dry when cooked. This is especially important when cooking methods like grilling or pan-frying are used, as these can quickly dry out the meat if it’s not properly tenderized. Overall, tenderizing flank steak is an essential step in preparing this cut of meat for cooking.
What are some common methods for tenderizing flank steak?
There are several common methods for tenderizing flank steak, including marinating, pounding, and braising.
