Before you start
Before beginning, ensure your beef chuck roast is removed from the refrigerator about 20 minutes prior to cooking to take the chill off. Dice the Roma tomatoes, white onion, and roasted Anaheim peppers into uniform pieces so they cook down evenly.
Mince the garlic cloves finely to ensure the flavor distributes throughout the beef as it cooks. If you are using pre-roasted peppers, ensure they are cooled enough to handle before dicing. Have your slow cooker clean and ready on a heat-safe surface, and ensure you have enough space to accommodate the beef and vegetables comfortably.
Ingredients at a glance (10)
- 3 lb beef chuck roast
- 3 anaheim peppers, roasted and diced
- 3 roma tomatoes, diced
- 1 white onion, diced
- 6 garlic cloves
- black pepper, to taste
- 200 ml beef broth
- 16 large eggs, for scrambling
- 2 cups shredded cheddar cheese
- 8 large flour tortillas
Instructions
Initial Assembly
- Assemble the slow cookerPlace the beef chuck roast into the bottom of the slow cooker. Add the roasted Anaheim peppers, diced Roma tomatoes, diced white onion, and minced garlic cloves. Season generously with black pepper. Pour the beef broth over the ingredients to provide moisture for the long cooking process.Look for Ensure the beef is mostly submerged or surrounded by the vegetables and broth.Tip Roasting the peppers beforehand adds a deeper, smoky dimension to the final shredded beef.
The slow cooker should be neatly layered with the beef, vegetables, and aromatics. The broth should be poured evenly over the top, just enough to moisten the ingredients without drowning them. Everything should be arranged to ensure even heat distribution during the long, slow-cooking phase that follows.
Slow Cook and Shred
- Slow cook and shredCover the slow cooker and set it to cook on low for 8.5 hours. Once the time is up, the beef should be fork-tender. Use two forks to shred the beef directly in the pot, allowing the meat to absorb all the accumulated juices and vegetable flavors until it reaches a fine, consistent texture. Ensure the beef reaches at least 145°F (63°C) and let it rest for at least 3 minutes before serving.Look for The beef should pull apart with almost no resistance when tested with a fork.Safe temperature 145°F (63°C) internal temperature (steaks, chops and roasts)Tip If the mixture seems too dry, add a splash more beef broth before shredding.
After 8.5 hours, the kitchen should smell deeply aromatic, with the scent of roasted peppers and savory beef. When you lift the lid, the beef should look darkened and soft. It should shred with minimal effort, and the surrounding liquid should have thickened slightly, creating a rich, flavorful sauce that coats the meat.
Final Assembly
- Prepare the breakfast burritosScramble the eggs in a hot skillet until fully set. Lay out the flour tortillas and warm them slightly. Fill each tortilla with a generous portion of the Machaca beef, fluffy scrambled eggs, and shredded cheddar cheese. Roll the tortillas tightly into burritos and toast them briefly in a dry pan until the outside is golden and the cheese is melted.Look for The eggs should be firm and cooked through to 160°F (71°C) to ensure food safety.Safe temperature 160°F (71°C) internal temperature (egg dishes)Tip For crispier burritos, toast the seam side down first to seal them securely.
The eggs should be light, fluffy, and completely cooked through. When the burritos are rolled and toasted, the exterior should be golden brown and slightly crispy, while the inside remains warm and cohesive. The cheese should be melted enough to bind the egg and beef together, creating a perfect, handheld breakfast meal.
Common mistakes
A common mistake is failing to remove excess large pieces of fat after the beef is shredded, which can create an unpleasant texture in the burritos. Another error is adding too much liquid; the beef and vegetables release a significant amount of moisture, so stick to the 200 ml of broth to avoid a watery mixture.
Finally, do not rush the shredding process. Take the time to separate the meat into fine threads, as this creates the signature texture that makes Machaca so unique and enjoyable to eat.
How to tell it’s done
The beef is done when it is extremely tender and pulls apart easily into fine threads with a fork. There should be no resistance when you press into the center of the roast.
The internal temperature of the beef should reach at least 145°F (63°C) for safety, though the long, slow cook time will naturally bring it well beyond this point, ensuring the collagen has fully broken down.
The scrambled eggs inside the burritos must be cooked until they reach 160°F (71°C), ensuring they are fully set and safe to consume.
- Steaks, chops and roasts: 145°F (63°C) in the thickest part, then a 3-minute rest
- Egg dishes: 160°F (71°C) in the thickest part
