Easy Flank Steak in the Crockpot

Flank steak is a flavorful cut of beef that is very lean. Because of this, it’s pretty tough, but slow cooking it in the crockpot breaks down all of the tough fibers, so it’s tender. 

For this recipe, it’s seasoned in some pantry seasonings and then simmered in beer and beef stock. The meat takes on all of those flavors, so it’s really delicious when it’s done. The flavors also pair with lots of other ingredients, so there are countless ways you can serve the flank steak.

This is an easy slow cooker recipe that you can prep early in the day and then leave until it’s ready. Plus, the leftovers keep well for three to four days in the refrigerator, so it’s great for meal prep, too.

  • Dried rosemary

How to Cook Flank Steak in a Crock Pot

Combine the seasonings in a small bowl, and then rub the mixture all over the flank steak.

Heat the olive oil in a large skillet over medium-high heat. Sear the steak for two minutes and then flip it over and sear it on the other side for two minutes.

Place the steak in the crockpot and add the beef stock and beer. Secure the lid and cook the flank steak on low for five to six hours or until the beef is tender and shreds easily.

Shred the beef before serving.

How to Serve Shredded Flank Steak

  • Cook some peppers and onions in a skillet and serve them with the steak and tortillas for easy beef fajitas.
  • Pile the meat in sliced rolls and top with cheese for delicious steak sandwiches.
  • Top cooked rice with the steak and add some vegetables like zucchini, mushrooms, and peppers.
  • Use it to make a delicious steak salad with lettuce, tomatoes, onions, cheese, and your favorite dressing.

I love this recipe because you can experiment with different seasonings to create different flavors – try other dried herbs, spices, or even adding some soy sauce, teriyaki sauce, or BBQ sauce to switch things up.

    We do this all the time but with meat that is already seasoned. But I will try this one also.
