Al pastor is the iconic Mexico City taco, showcasing a stack of pork that has been marinated for days, cooked on a rotating spit and then sliced and crisped to order. If you want that same robust flavor but are lacking in specialized equipment and time, try this version which uses the instapot! Flavored with fresh Mexican spices, it can certainly be a credible stand-in for the authentic Mexican al pastor.Jump to Recipe
What makes Instapot Tacos al Pastor Low Carb?
The pork shoulder is the star of any al pastor recipe and it needs to be cooked to the tender stage, regardless of the cooking method. The instapot can be an effective method for getting the tenderness, and then it is a matter of whether you want to crisp it to finish or just stir into the sauce.
Because I am striving to make everything as easy as possible these days, I simply added it to the Mexican-spiced sauce to finish. For a great carnitas recipe where you do crisp the pork, see this post.
The pineapple is a problem for low carb or keto people. There is just no getting around how much sugar is in pineapple. In one cup of pineapple there are 22 grams of carbs and 16 grams of sugar. I tried to come up with a low carb alternative to the pineapple but really it is such a classic addition to al pastor that it’s probably better to go ahead and use pineapple, but just use it more sparingly.
Because I was making this for family and I had no pineapple available, I used a bit of quince paste to give it a touch of fruity sweetness. I needed to figure out how to use that quince paste that was sitting in my pantry for so long, and I think using it instead of the pineapple really elevated this dish and made it unique. Quince is not low carb either however, so use your preferred fruit.
The other carby ingredient of course is the tortillas. I have a couple of recipes and suggestions for low carb tortillas here. The following recipe used store-bought low carb tortillas.
So, to keep the integrity of al pastor but still get the delicious taste, focus on using really fresh spices, and great pork and then just go easy on the pineapple. We used pickled red onions to up the flavor even more. Click here for an easy, quick pickled onion recipe.
