Understanding the Carbohydrate Challenge of Traditional Al Pastor
Traditional al pastor is a flavorful dish featuring pork marinated in a mixture of chiles, spices, and pineapple, then cooked on a vertical rotisserie known as a trompo. The primary sources of carbohydrates that make traditional al pastor problematic for a keto diet are:
- Pineapple: The pineapple, which is traditionally cooked with the pork and often served as a topping, is high in sugar and thus high in carbs. Just one cup of chopped pineapple contains over 20 grams of carbs.
- Tortillas: Tacos al pastor are almost always served on corn tortillas, which, while smaller than flour tortillas, still contribute significantly to the total carb count and should be avoided on a strict keto diet.
Making Al Pastor Keto-Friendly: The Key Modifications
The secret to enjoying al pastor on keto lies in removing the high-carb components and finding suitable, flavorful replacements. This allows you to savor the rich, spiced pork while keeping your net carb count low.
Marinade and Cooking Adjustments
To create a keto-friendly al pastor, you must alter the marinade. The flavor profile is driven by a blend of dried chiles (like guajillo and ancho), achiote paste, cumin, and Mexican oregano. While pineapple juice is a traditional tenderizer and adds sweetness, it can be replaced easily.
- Replace Pineapple Juice: Instead of pineapple juice, use a combination of cider vinegar and fresh orange or lime juice. Use the juice sparingly to add acidity without loading up on sugar. A tiny amount of a keto-friendly sweetener like erythritol can also mimic the sweetness of pineapple.
- Spice-Forward Marinade: Focus on a robust blend of spices and chiles. Don't be afraid to add more chipotle powder for a smoky kick. A high-quality achiote paste is a must-have for authentic flavor and color.
- Cook for Flavor: If you don't have a vertical spit, a slow cooker or instant pot can yield tender, flavorful pork. For that signature caramelized char, shred the cooked pork and crisp it up in a hot skillet with some of the rendered fat.
Serving Options for a Keto Al Pastor Meal
Instead of serving the al pastor meat in high-carb tortillas, you have several delicious low-carb options:
- Lettuce Wraps: Large, sturdy lettuce leaves, such as romaine or butter lettuce, make excellent, crunchy vessels for the meat.
- Over a Salad: Serve the al pastor over a bed of mixed greens with other keto-friendly toppings like avocado, pico de gallo, and sour cream.
- In a Bowl: Create a keto al pastor bowl with cauliflower rice as the base. Top with the pork, fresh cilantro, onions, and cheese.
- Low-Carb Tortillas: Many grocery stores now carry low-carb or almond flour tortillas that can work for a more traditional taco experience while managing your carb intake.

A Sample Keto Al Pastor Recipe
Here is a simple, high-impact recipe to make keto al pastor at home.
Ingredients:
- 2 lbs boneless pork shoulder, cut into 1/4-inch slices
- 3 dried guajillo chiles, stemmed and seeded
- 1/4 bar achiote paste (about 1.5 oz)
- 1/4 cup apple cider vinegar
- 1/2 tsp Mexican oregano
- 1 tsp cumin
- 1/2 tsp chipotle powder
- 3 cloves garlic
- 1/2 small white onion, roughly chopped
- Salt to taste
- Olive oil or avocado oil
Instructions:
- Prepare the Marinade: Soak the dried chiles in hot water for 15 minutes to soften. Drain and blend them with the achiote paste, apple cider vinegar, oregano, cumin, chipotle powder, garlic, and chopped onion until you have a smooth paste. Add a little water if needed to help it blend.
- Marinate the Pork: Place the sliced pork in a resealable bag and pour the marinade over it. Massage to coat evenly. Refrigerate for at least 3 hours, or overnight for best results.
- Cook the Pork: Heat a tablespoon of oil in a large skillet or Dutch oven over medium-high heat. Sear the marinated pork slices in batches until browned, then reduce heat and cook until tender. For a crispier finish, shred the pork and then briefly fry it again in the hot pan with a bit of fat.
- Serve: Serve in lettuce cups or low-carb tortillas with your favorite keto-friendly toppings like chopped onions, cilantro, and a squeeze of lime juice.
