Understanding Flank Steak

Flank steak, cherished for its rich flavor and adaptability, is ideally suited for slow cooking. This lean cut comes from the cow’s abdominal muscles and is known for its grainy texture. Slow cooking breaks down the fibers, making the meat incredibly tender.

Selecting Your Ingredients

A successful dish starts with quality ingredients. Here’s what you’ll need:

  • 2 lbs of flank steak: The star of your dish. Look for a piece that’s uniformly thick to ensure even cooking.
  • Marinade components: Combine soy sauce (1/4 cup), minced garlic (2 cloves), and beef broth (1/2 cup) to create a flavorful bath that will infuse the steak with moisture and taste.
  • Vegetables: While optional, adding vegetables like sliced onion, carrots, bell peppers, and mushrooms can turn your flank steak dish into a complete meal.

For the best results, sourcing your flank steak from a reputable butcher is recommended. A high-quality cut not only enhances the flavor but also the overall tenderness of the dish. Find out more about selecting the best flank steak.

Preparing the Meat and Veggies

  1. Trim and Slice: Start by trimming any excess fat from the flank steak to avoid greasiness. Then, slice the steak against the grain into strips. This is crucial for ensuring the meat is tender and easy to eat.
  2. Marinate: In a bowl, whisk together the soy sauce, garlic, and beef broth. This marinade will tenderize the steak and infuse it with rich flavors. Place the steak strips and sliced onion into the crock pot, and pour the marinade over them, making sure the meat is well-coated.
  3. Vegetable Prep: If you’re adding vegetables, prepare them by washing and slicing them into bite-sized pieces. They can be added to the crock pot either at the beginning with the steak for softer veggies or partway through cooking for crisper ones.

Cooking Your Flank Steak to Perfection

After preparing your flank steak and assembling your ingredients, it’s time to slow cook your way to a delectable meal. This part of the guide will walk you through the crock pot cooking process, ensuring your flank steak achieves the perfect balance of tenderness and flavor.

The Slow Cook Process

The magic of the crock pot lies in its ability to tenderize meat over several hours, making it an ideal method for cooking flank steak. Here’s how to ensure your steak is cooked perfectly:

  1. Layering: Place the marinated flank steak and onions at the bottom of the crock pot. If you’ve decided to include vegetables, layer them on top of the meat. The direct heat from the bottom will cook the steak thoroughly, while the vegetables steam above.
  2. Cooking Time and Temperature: Set your crock pot to low heat. Cooking the flank steak on a low setting for 6-8 hours allows the connective tissues to break down without drying out the meat, ensuring it’s tender and juicy. If you’re short on time, a high setting for 3-4 hours can work, but the meat may not be as tender.
  3. Checking Doneness: The steak is ready when it’s extremely tender and easily shreds with a fork. Avoid lifting the lid frequently during the cooking process, as this can extend the cooking time.

Finishing Touches

Once your flank steak is tender and flavorful, a few final steps will complete your dish:

  • Thickening the Sauce: If you prefer a thicker sauce, mix 2 tablespoons of cornstarch with 2 tablespoons of water to create a slurry. Pour this into the crock pot, stirring gently to mix. Turn the heat to high and let it cook uncovered for an additional 15-20 minutes, or until the sauce thickens.
  • Serving: Carefully remove the flank steak and vegetables from the crock pot, placing them on a serving dish. Drizzle with the thickened sauce to enhance the flavor.
  • Sides: Complement your flank steak with sides that will soak up the delicious sauce. Mashed potatoes, rice, or crusty bread are excellent choices. Fresh, steamed vegetables or a crisp salad can add a refreshing contrast to the rich, savory flavors of the meat.

Cooking flank steak in a crock pot is a straightforward process that yields incredibly tender and flavorful results.

The Sauce Is Too Thin

  • For those preferring a thicker sauce, use a cornstarch slurry to achieve the desired consistency. Mix equal parts cornstarch and water, then stir into the crock pot. Increase the heat and allow the sauce to thicken.

The Flavor Is Too Mild

  • If the flavor of your flank steak isn’t as robust as you’d like, consider adding more seasonings towards the end of the cooking time. A splash of soy sauce, a pinch of salt, or a dash of Worcestershire sauce can enhance the dish’s overall flavor profile.
