How To Cook Flank Steak in the Crock Pot
Now, let’s dive into the step-by-step instructions for cooking flank steak in the slow cooker. This simple process will guide you through each step, ensuring your steak turns out perfectly tender.
Step 1: Season the steak
Start by seasoning your flank steak with salt, pepper, and any dried herbs you like.
Step 2: Sear the steak
Heat some olive oil in a large skillet over medium-high heat. Once hot, sear the steak for about 2-3 minutes on each side until it gets a nice brown crust. This adds tons of flavor and helps lock in moisture.
Step 3: Prepare the slow cooker
Grab your slow cooker and place the sliced onion and garlic at the bottom. These will cook down and create a tasty aromatic base for the steak.
Lay the seared flank steak in the crock pot right on top of the onion and garlic.
Step 4: Slow cook
Pour in the beef broth, soy sauce, and balsamic vinegar. These ingredients add a nice depth of flavor and keep the steak juicy while cooking.
Cover the slow cooker and let it cook on low for 6-8 hours, or until the steak is so tender it shreds easily.
Step 5: Shred and serve
Once the steak is ready, remove it from the slow cooker, shred it with a fork, and return it to the pot to soak up all those delicious flavors. Serve it with your favorite sides.
How To Serve Flank Steak
- In Tacos: Shred the flank steak and serve it in soft or hard taco shells with your favorite toppings like salsa, guacamole, and cilantro.
- Over Rice: Serve sliced or shredded flank steak over a bed of fluffy rice, paired with sautéed vegetables for a complete meal.

Flank Steak Slow Cooker Recipe Pro Tips
- Sear the Steak First: For the best beef flank slow cooker results, sear the steak first. This helps lock in flavor and gives it a nice crust.
- Use Enough Liquid: Make sure there’s enough broth or liquid to cover the steak halfway, so it stays moist and tender.
- Let it Rest Before Shredding: Let the meat rest for a few minutes after cooking to make it easier to shred. This also prevents the juices from leaking out.
- Add Veggies for Extra Flavor: Add vegetables like carrots, bell peppers, or potatoes to the crockpot for a complete meal.
- Adjust Seasonings: Taste the cooking liquid halfway through and adjust salt, pepper, or balsamic vinegar to match your taste.
- Use Leftovers for Other Meals: Shredded slow cooker flank steak is perfect for tacos, sandwiches, or salads!
Beef Flank Slow Cooker Recipe FAQs
For the best flank slow cooker results, cook on low for 6-8 hours. Searing the steak before slow cooking helps lock in moisture, and using enough liquid (like beef broth) keeps the meat tender.
Yes, you can substitute other cuts of beef, like skirt steak or chuck roast. Just keep in mind that cooking times and textures may vary. Chuck roast, for example, has more fat and will become even more tender but can become stringy if overshredded.
Yes, you can use frozen flank steak, but it’s best to thaw it in the fridge before cooking for even results. If you’re using it from frozen, be sure to add extra time to the cooking process (around 1-2 hours), as it will take longer to cook through.
Store leftover steak in an airtight container in the fridge for 3-4 days, adding cooking liquid to keep it moist. To freeze, shred the steak and store it with liquid in a freezer-safe bag or container for 2-3 months.
Reheat in a covered pan on low with broth or water, or microwave in short intervals, adding moisture as needed.
