Instant Pot or Slow Cooker Low-Carb Flank Steak Tacos!
If you’re an Instant Pot fan, you probably noticed that I have a growing collection of pressure cooker/Instant Pot recipes on this site. But while I’ve been featuring recipes made in the pressure cooker or the Instant Pot I’ve also been hearing from people who still love their slow cookers, and want to make sure I don’t forget about the slow cooker! And what I’ve realized over and over is that so many of the recipes I loved in the slow cooker can also be adapted to the Instant Pot, and vice versa. So I’ve been updating the recipes where I feel there are two options for the cooking method, and one that I think you should definitely try in the Instant Pot or the Slow Cooker is these Low-Carb Flank Steak Tacos. This recipe is such a keeper with the Spicy Mexican Slaw!
I adapted the beef part of the recipe from one in The Easy Pressure Cooker Cookbook that used flank steak. I haven’t cooked flank steak too much, and it’s not the cheapest cut of beef you could use for tacos, but I loved these flank steak tacos because the meat shredded apart just the right amount, and the flavor was great too. I made the recipe low-carb by using my favorite Mission Carb Balance Tortillas and making sure to choose a salsa without added sugar, but if you don’t care about low-carb just use any tortillas you prefer. And I was surprised at how the carbs added up when I calculated them for this recipe, but some of the higher-carb sauce will be left in the pressure cooker. For a version that’s lower in carbs, go easy on the slaw and use lettuce wraps for serving.
But please, please, please do try making Low-Carb Flank Steak Tacos if you have an Instant Pot (affiliate link) or a Cuisinart Electric Pressure Cooker (affiliate link) (or even a stovetop model.) You will love these tacos, I promise. And if you’re not a pressure cooker fan, see the recipe below for slow cooker instructions, or you can use my recipe for Slow Cooker Green Chile Shredded Beef Cabbage Bowl to make the beef if you prefer!
How to Make Pressure Cooker (or Slow Cooker) Low-Carb Flank Steak Tacos:
(Scroll down for complete recipe, including slow cooker instructions and nutritional information.)
- Cut up onion and measure the spices.
- Turn the pressure cooker to saute (or medium-high heat on the stove), add the olive oil, and cook the onions for a few minutes, then add the spices and cook about a minute more.
- While onions cook trim the flank steaks and cut in half both lengthwise and crosswise.
- Add the flank steak, tomato salsa, and salsa verde to the pressure cooker.
- Set to MANUAL, HIGH PRESSURE, 45 minutes. Use natural release for 15 minutes, then quick-release to release the remaining pressure.
- Use a slotted spoon (affiliate link) to fish out the pieces of meat, leaving the sauce in the pressure cooker. (You can cook off some of the water if you think the sauce looks too thin.)
- Let meat cool for a few minutes on a cutting board, then shred it apart with two forks. Put meat back into the pressure cooker and stir to combine with the sauce.
- Make half the recipe of Spicy Mexican Slaw (or other slaw of your choice that would be good with spicy taco meat.)
- Heat a cast-iron frying pan and use it to warm one tortilla at a time; then fill the tortillas with some meat and slaw. (I like Mission Carb Balance Tortillas for this recipe.)
- Serve the tacos with extra lime and Green Tabasco Sauce (affiliate link) to add at the table if desired. I like them with a lot of lime!

Low-Carb Diet / Low-Glycemic Diet / South Beach Diet Suggestions:
Obviously you need to use low-carb tortillas like the ones I used if you’re making these tacos for any type of low-carb diet or the South Beach Diet Also check the tomato salsa and salsa verde and buy the brand with the least amount of sugar if you’re wanting this to be a carb-conscious meal. (Some salsa has a lot of added sugar.) These tacos are phase two or three for South Beach if made with tortillas, but for a Phase One, gluten-free, or Paleo option, this beef would be delicious inside lettuce wraps.
