What is Beef Machaca?
Beef Machaca is a traditional Mexican dish featuring shredded beef that’s been slow-cooked with aromatic spices, tomatoes, and peppers. The result is a flavorful and juicy filling that can be used in various dishes such as tacos, burritos, enchiladas, or served over rice. Traditionally, machaca was made by drying and pounding beef, but modern recipes (like this one) rely on slow cooking to achieve that tender, pull-apart texture.
Ingredients List for Slow Cooker Beef Machaca
Here’s what you’ll need to make this delicious Slow Cooker Beef Machaca:
- Beef Chuck Roast (2-3 pounds): This cut of meat is perfect for slow cooking because it becomes tender and shreds easily after hours of cooking.
- Onions (1 large, chopped): Adds a base layer of flavor to the dish.
- Garlic (4 cloves, minced): Garlic enhances the savory depth of the beef.
- Green Bell Pepper (1 large, chopped): Adds texture and a mild sweetness.
- Jalapeño (1, seeded and chopped): For a little bit of heat. You can add more or less depending on your spice tolerance.
- Crushed Tomatoes (1 can, 14.5 ounces): The tomatoes give the machaca its saucy consistency and a slight tang.
- Beef Broth (1 cup): Keeps the beef moist and flavorful while it cooks.
- Cumin (1 teaspoon): This adds warmth and earthiness to the dish.
- Chili Powder (1 tablespoon): Gives the machaca a smoky, spicy flavor.
- Oregano (1 teaspoon): Mexican oregano adds a fragrant, herby note.
- Bay Leaves (2): Adds an aromatic touch to the slow-cooked beef.
- Lime Juice (2 tablespoons): A squeeze of lime at the end brightens up the flavor.
- Salt and Pepper (to taste): Essential for seasoning the beef.
Substitutions and Variations for Slow Cooker Beef Machaca
Machaca is versatile, so don’t be afraid to experiment with substitutions and variations to suit your taste or dietary needs. Here are a few ideas:
- Meat Substitutions: If you’re not a fan of beef or want a leaner option, you can substitute with chicken thighs or pork shoulder. Both will shred easily after slow cooking.
- Vegetarian Option: For a plant-based version, you can use jackfruit or mushrooms. They have a meaty texture that works well when shredded.
- Spice Level: Adjust the heat by adding more jalapeños, serrano peppers, or even chipotle peppers in adobo sauce for a smoky kick.
- Tomato Options: Swap the crushed tomatoes for fire-roasted tomatoes to add a smoky flavor to the dish.
- Broth Substitutes: If you don’t have beef broth, you can use chicken broth or even water with a beef bouillon cube dissolved in it for added flavor.
Step-by-Step Cooking Instructions for Slow Cooker Beef Machaca

Now that you’ve gathered all your ingredients, let’s walk through the step-by-step process for making delicious Beef Machaca in your slow cooker:
- Prepare the Beef: Start by patting the beef chuck roast dry with paper towels. Season generously with salt and pepper on all sides. This step is crucial for building flavor as the meat cooks.
- Sear the Beef (Optional): If you have time, sear the beef in a hot skillet with a bit of oil before placing it in the slow cooker. Searing adds a deeper, richer flavor to the final dish, but this step can be skipped if you're short on time.
- Layer the Ingredients in the Slow Cooker: Place the chopped onions, garlic, green bell pepper, and jalapeño in the bottom of the slow cooker. Add the seasoned beef on top of the vegetables. Pour in the crushed tomatoes and beef broth over the beef.
- Add Spices: Sprinkle the cumin, chili powder, and oregano over the beef. Tuck in the bay leaves.
- Cook Low and Slow: Set the slow cooker to low and cook for 8-10 hours or on high for 5-6 hours. The beef is done when it is tender and easily shreds with a fork.
- Shred the Beef: Once the beef is fully cooked, remove it from the slow cooker and shred it using two forks. Discard any large pieces of fat. Return the shredded beef to the slow cooker to soak up all the delicious juices.
- Add Lime Juice: Before serving, stir in the fresh lime juice. This adds brightness and balance to the rich flavors of the dish.
- Adjust Seasoning: Taste the machaca and adjust seasoning with more salt, pepper, or spices if needed.
How to Cook Beef Machaca: A Step-by-Step Guide
In summary, here’s a quick guide to cooking Beef Machaca in your slow cooker:

Common Mistakes to Avoid When Making Beef Machaca
