What is carne asada?

Mexican-inspired carne asada is grilled beef that has been marinated in dry spices and lime juice. Cooking it on the grill gives it a char on the outside and helps it taste smoky and tender on the inside. Once it’s cooked, the meat is cut into thin strips so it’s easy to add to a tortilla. This recipe is similar to traditional carne asada but made easier in the crockpot. It’s best served with a side of rice, beans, or green salad or can be put into tacos, enchiladas, burritos, or even used to top a plate of nachos.

The best meat for steak tacos

When choosing meat for steak tacos, you want to make sure your choice has a good amount of fat and marbling for plenty of flavor. I like using beef sirloin but you can also use flank steak, strip steak, skirt steak, or even beef tenderloin. When it comes to tougher cuts of beef such as skirt and flank steak, make sure you slice it thin to keep it as tender as possible when cooking.

How to make carne asada in a slow cooker

Cut the beef into strips and season it with garlic powder. Rub it thoroughly into the meat and add it to a skillet over medium heat until the strips have browned. Stir the beef broth and cornstarch together in the bottom of the slow cooker. Next, add in the beef strips, onion, diced tomatoes, cumin, chili powder, and salt. Stir it all together. Slowly cook the carne asada on high for 2 and a half hours. Afterward, throw in the sliced green peppers and cook for an additional 1 hour on high. After 3 hours, 30 minutes total, the carne asada beef will be done. Remove the beef from the crockpot and serve on tortillas or hard shells with cheese, salsa, lettuce, avocado, or whatever else you like on your tacos.

Steak taco toppings

Customize these carne asada tacos by adding all of the toppings you love! Here’s what I suggest using for a loaded and flavorful steak taco:

Storing and reheating leftovers

To store: Any leftover pepper steak taco mix can be stored in an airtight container in the fridge for 3 to 4 days. To freeze: Store the cooked and cooled carne asada in an airtight container or freezer-safe bag with the air removed for up to 3 months. Thaw in the fridge before reheating and serving. To reheat: To reheat the beef taco mix, add it to a skillet over medium heat until warmed through for the best results. You can also reheat it in the microwave.
