Tender slow cooker shredded beef simmered with cumin, garlic and green enchilada sauce, just like Cafe Rio. Pile it into warm tortillas with creamy tomatillo dressing and your favorite toppings.
Cut the onion into thick, chunky slices and spread them over the bottom of the slow cooker.
Place the chuck roast on top of the onions.
In a bowl, stir together the beef broth, 1 tablespoon cumin, garlic and tomato sauce. Pour it over the roast.
Cover and cook on LOW for 6 to 8 hours, until the beef pulls apart easily with a fork.
Transfer the beef to a cutting board and shred it with two forks, discarding any large pieces of fat.
Strain the juices from the slow cooker into a bowl and save them. Return the shredded beef to the slow cooker.
Pour some of the strained juices over the beef, a little at a time, until it is moist but not soupy.
Stir in the green enchilada sauce and tomato paste. Season with salt and extra cumin to taste, then cover and let it heat through on LOW for about 15 minutes.
Serve in warm soft tortillas with your favorite toppings and a drizzle of the tomatillo dressing.
For the creamy tomatillo dressing
Add all the dressing ingredients to a blender or food processor and blend until smooth and creamy. Taste and adjust the lime, salt or jalapeno as needed. Refrigerate until ready to use.
Notes
Adapted from: Eat Cake for DinnerCooking time: LOW for 6 to 8 hours gives the most tender beef. HIGH for 4 to 5 hours works in a pinch.Juices: add the strained cooking liquid back a little at a time so the beef is moist but not soupy, especially for burritos.Storage: refrigerate the beef with some of its juices for up to 4 days, or freeze for up to 3 months. The dressing keeps about 5 days in the fridge and doesn't freeze well.
