Crock Pot Beef Fajitas

Crock Pot Beef Fajitas are easy to make and filled with rich flavor, and delicious juices. Using your favorite beef, cut it into strips and brown for a delicious crust. Place it in your crock pot for a few hours allowing that meat to tenderize and infuse with the seasonings.

We make these easy crock pot beef fajitas with the classic ingredients including onion and pepper strips which are added to the crock pot in the final stages of cooking for the absolute best fajitas. Serve with hot, homemade flour and butter tortillas, and you have steak fajitas that will outshine any restaurant.

How do you cook fajita meat so it is tender?

To make tender fajitas you need to cook the meat low and slow, allowing it to soften and infuse with the spices; this is why we love crock pot beef fajitas. The crockpot cooks the meat gently while marinating it in the natural juices and seasonings which always yields tender strips of beef and deep flavor.

Browning the strips of steak is a great way to not only add that extra layer of flavor, but also to help lock in the juices of the meat, helping to prevent drying out. Fajitas are all about the natural flavors of the steak and the simple spices coming together with peppers and onions for an authentic Mexican dish.

How do you brown the beef strips?

  • Cut your steak into thin slices roughly 3 inches long and 1/4 inch thick
  • Heat a heavy bottomed stainless steel or cast iron skillet with avocado oil
  • Lightly season the beef strips with salt and pepper
  • Carefully place the strips of meat in the skillet and cover to contain any splattering
  • Allow the strips to brown on each side so that a slight crust forms
  • Remove the meat from the skillet and transfer to your heated crock pot

Which steak cut is best for fajitas?

Skirt steak is the traditional choice for fajitas because it is located near the belly of the cow making it tender and buttery. However, if cost is a concern you can choose flank steak which is less expensive, but very similar.

Why is my fajita meat chewy?

In order to yield tender, juicy fajita strips you need to cook the meat properly. There are a variety of details to keep in mind when preparing delicate cuts of meat that need to be tender and juicy.

Be careful not to cook it too hot. High heat will evaporate the natural juices and dry out the meat. This is especially important when dealing with thin cuts. Cook the meat low and slow to preserve the juices, and make sure there is enough liquid for the meat to cook and marinade in.

Introduce an acid to tenderize the meat. Your crock pot beef fajitas will benefit from a marinade that contains some sort of acidic ingredient; either citrus juice or vinegars. This will help to break down the connective tissues resulting in softer strips of meat.

How you cut the meat matters. Slice your steak against the grain rather than along with the grain. This matters because the muscle fibers run in one direction, and if you cut the meat improperly these fibers will be more noticeable when you chew.

Is it worth making your own tortillas?

We sure think so! Crock Pot Beef Fajitas are absolutely delicious and even more so when you serve them with hot, fresh tortillas. The flavor and texture of homemade tortillas simply cannot be beat, and they aren’t that hard to make. We use our homemade flour tortillas any chance we get.

Making your own tortillas can also be much less expensive than buying tortillas because there are very few ingredients and none of which cost very much.

Is it better to roll or press flour tortillas?

You want to use a rolling pin when making your own flour tortillas. A tortilla press will apply too much pressure to the tender texture of the flour tortillas, causing them to lose moisture and most likely resulting in flat, dense tortillas.

Corn tortillas have a dense texture that can withstand the pressure of a press. A tortilla warmer though? Now that we do recommend. You want your tortillas to stay warm and soft, so be sure to cover and insulate them right when you take them off the skillet.
