These easy Slow Cooker Steak Tacos are a great dinner that you can set and forget using your crockpot. Simply combine sirloin steak, seasonings, peppers, and onions for a tender beef taco that’s tortilla-ready. Great for weeknight dinners and delicious leftovers!

Easy slow cooker street tacos
Whether it’s taco Tuesday or any day of the week, making tacos in your slow cooker is always a good idea! The ingredients are so easy to prep the night before and you can set it and forget it in your crockpot. After a few hours, you’ll be indulging in deliciously tender and seasoned beef loaded into tortillas with your favorite salsa.
Beef sirloin, peppers, onions, and taco seasonings are combined in a crockpot along with some broth and cornstarch. After letting the slow cooker work its magic, you’ll end up with taco-ready carne asada and a thick and flavorful sauce that goes so well over the beef.
When you’re ready to eat, simply serve the beef on tortillas with your favorite toppings like shredded lettuce, cheese, or Homemade Tomato Salsa. Pair them with a side of Cilantro Lime Rice or a Mexican Corn and Black Bean Salad. And if you like these pepper steak tacos, don’t forget to try my easy recipe for Crockpot Chicken Tacos and Slow Cooker Taco Soup!

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:
- Shredded lettuce
- Diced tomato
- Shredded cheese
- Pickled onions
- Sliced, pickled or candied jalapenos
- Tomatillo salsa
- Sliced radishes
- Guacamole
- Tomato salsa
- Black Bean corn salsa
- Sour cream
- Coleslaw
- Hot sauce
- Roasted corn
- Caramelized onions
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.

Slow Cooker Steak Tacos
PrintIngredients
- 2 pounds beef sirloin (or ribeye)
- 2 teaspoons garlic powder
- 3 tablespoons vegetable oil
- 1/2 cup beef broth heated up
- 1 tablespoon cornstarch
- 1 small onion chopped
- 14 oz can diced tomatoes
- 1 teaspoon cumin
- 2 teaspoons chili powder
- 1/2 teaspoon salt
- 2 green peppers sliced
Instructions
- Cut your beef sirloin into 2 inch strips. Sprinkle garlic powder on top of them, rubbing it in.
- In a skillet over medium high heat, add vegetable oil and beef strips. Brown sirloin strips (takes about 10 minutes), drain grease and set aside.
- Add beef broth and cornstarch to the bottom of the slow cooker and mix so cornstarch is dissolved. You want your beef broth to be hot so the cornstarch is dissolved, I throw mine in the microwave for 30 seconds.
- Add beef strips into the slow cooker on top of broth mixture.
- Add onion, diced tomatoes, cumin, chili powder and salt into the slow cooker mixing to combine all ingredients.
- Cover and cook on HIGH for 2 hours, 30 minutes. Add sliced green peppers and cook an additional 1 hour on HIGH. So the total time is 3 hours, 30 minutes.
- Serve on tortillas or hard shells, add cheese, salsa, lettuce, avocado or whatever else you'd like on top.

I love tacos and taking this very simple recipe one step further is making it in the crockpot. I bet the beef strips were very tender and delicious. A great alternative to the usual ground beef version.

Definitely, it makes the beef just fall apart.. taco perfection in my eyes! Thanks for stopping by!

jackie @ Marin mama cooks says
Hey Pamela! We love tacos as well and they are a weekly menu staple in our house. You know whats funny? I’m totally not a slow cooker gal. My friends are always sharing their favorite slow cooker recipes with me to use on the blog. I haven’t had the best experience with using the slow cooker. Either I overcook the meat or it turns off in the middle of it’s cycle for some reason. I think if I was working out of the house, I would use it more, but since I’m not, I tend to cook things the old fashioned way ๐
I love how you wrapped up your tacos like they’re in cute little blankets! So adorable! I also love how you always use everything from your garden. I can’t wait till you have your own gardening show! xoxo, Jackie
Pamela says
Thanks Jackie! I hope you are able to use your crockpot at least once this year! I always feel like it does wonders to meat to make it fall apart. I call it my magic box! You just throw a bunch of food in there and magic comes out!
Monica says
It has gotten so much cooler this week and I’m totally craving something like this to eat! I want meat! I need to pull out my crockpot/slow-cooker now…
Pamela says
Get it out Monica! The time has come!

We loveeee tacos in our house. My favorite night of the week is taco night : ) I like that this is done in the crockpot … I really need to use mine more often (I only seem to take it out once a month or so!)
Pamela says
