Slow Cooker Beef Tacos Al Pastor
These Slow Cooker Beef Tacos Al Pastor are smoky, sweet, spicy, and incredibly easy to make. Instead of the traditional pork cooked on a vertical spit, this shortcut version uses beef chuck roast in the slow cooker for tender, shredded taco meat.
The result? Juicy beef with pineapple, chipotle, lime, cotija cheese, and avocado. Basically, taco night just got a very delicious upgrade.
What Are Tacos Al Pastor?
Traditional tacos al pastor are usually made with marinated pork cooked on a vertical spit, similar to shawarma. The meat is sliced thinly and served in corn tortillas with pineapple, onion, cilantro, and lime.
This version is inspired by those classic flavors but uses beef and a slow cooker to make the process simple for busy weeknights or casual entertaining.
Why You’ll Love These Beef Tacos
- Made in the slow cooker
- Tender shredded beef
- Sweet and spicy pineapple-chipotle sauce
- Perfect for taco bars and parties
- Easy to customize with toppings
Sweet, Smoky, and Spicy Flavor
The flavor comes from crushed pineapple, chipotle peppers in adobo, apple cider vinegar, and onion. Together, they create a sauce that is sweet, smoky, tangy, and spicy.
If you prefer a milder taco, simply use fewer chipotle peppers and add more pineapple on top when serving.
Perfect for a Taco Bar
The next time you host a casual dinner or game night, make a taco bar. Keep the beef warm in the slow cooker, then set out tortillas, pineapple, avocado, cotija cheese, lime wedges, and cilantro.
As a result, everyone can build their own tacos exactly how they like them.

Hi, this recipe looks fantastic, Very unique flavors – would you clarify these items though…
2-3 in Chipotles Adobo Sauce <– does this mean 2-3 inches of chiles WITH some of the sauce? How much sauce?
1 Tablespoon of Chili Sauce = chili sauce is kind of a general term, what brand did you use so I can look it up to see what it is exactly
thanks
Hi Jo, let me clarify for you:
When you open the can or chipotles, you actually get pieces of chipotle. So just grab 2-3 pieces that come attached with sauce. you may add more if you like the heat.
For the Chili sauce, you can use sriracha, Heinz Chili sauce or even Tabasco.
