Why Choose a Slow Cooker for a Flank Steak?

With its leanness comes the difficulty of preparing it improperly or overcooking it, making it tough. It’s, however, very tender when cooked in a slow cooker.

The slow time also permits the fajita seasoning to soak all the way down involving the steak, peppers, and onions, guaranteeing that each nibble is showered with flavor. And the best part? Once you prep the slow cooker, you can let all the hard work be done for you.

How to Prepare Soft Slow Cooker Flank Steak Fajitas

After that long and detailed preparation of the ingredients, let’s cook the meal itself! Here step by step instructions for preparing delicious, soft, and tender flank steak fajitas in the slow cooker.

Step 1: Prepare the Steak

Begin improving your flank steak Within this case, you need to do the following. You should then remove any excess fat off the body of the meat while retaining the lean meat. Sometimes you want to retain a small layer of fat for flavor but that too much fat will make the food greasy. Having trimmed the steak, it is then cut into large chunks (3-4 pieces) in order to fit into the pot and in order that the seasoning would get through the meat.

Step 2: Sear the Steak

For effectiveness, this is sharply brought by the slow cooker; however for more enhanced taste, the steak should first be browned. For the next layer, heat 2 tablespoons of olive oil in a large skillet over medium-high heat. When the oil is hot, you should place the flank steak pieces, and fry them until both surfaces turn to gold brown colour.

Heat searing aids in retention of the juices within the steak to make it tender together with rich in flavor. When cutting the steak, and after searing, place the steak on your slow cooker.

Step 3: Prepare the Vegetables

When the steak is getting ready for flipping, wash the vegetables and slice your bell peppers and onion. The peppers and onions will add a lot of flavors to the steak and with the help of slow cooking the peppers and onions will become tender. Place sliced peppers and onions on the steaks that are in the slow cooker.

Step 4: Add the Fajita Seasoning

In a small bowl, combine all the fajita seasoning ingredients: chili powder, cumin, paprika, garlic powder, onion powder, oregano, salt, black pepper and chili flakes (in case they are used). Combine them to form a standard seasoning mix.

Just as a dish of fajitas would ideally come with cheese and other fixings, fajita seasoning should be evenly poured over the steak and vegetables in a slow cooker. Pour beef broth and also half cup of this broth at this stage to help in maintaining a moist environment when precooking. The broth will also react with the seasonings to help dissolve or marinate the steak and the vegetables.

Step 5: Slow Cook the Flank Steak

Put lid on slow cooker, set to low heat and slow cook it for the next 6 hours. When you cook it with low heat, the flank steak takes a long time to cook without getting tough, and the veggies cook through just as they should. The seasoning used on the fajita will marinade the steak and veggies, making them taste fantastic when filled in the tortilla.

Step 6: Shred the Steak

After you have reached 6 hours on slow cooking, ensure you are careful when taking out your flank steak from the slow cooking pot. It has to be very soft such that it can be easily crushed with a fork. split the steak with two forks into small pieces, and to make sure, mix it with the cooked peppers and onions.

Step 7: Assemble the Fajitas

The tortillas should be warmed up in a skillet, without oil, or in the microwave. Then, put several spoonfuls each of the shredded up steak and vegetables in the center of each tortilla. The toppings for the chili should be sour cream, cheese, guacamole, salsa, sprigs of cilantro and a little lime juice should do.
