Tips for success

For the best flavor, use a high-quality salsa that you enjoy eating on its own. The salsa's flavor will intensify during cooking, so choose one with a good balance of heat and smokiness. If you prefer a spicier dish, add a chopped jalapeño or a dash of hot sauce before cooking. You can also stir in some ground cumin or chili powder for extra warmth.

To achieve a perfectly blistered cheese crust, avoid stirring the cheese into the mixture during cooking. Let it melt and bubble on top, creating a golden, slightly charred layer. If you want even more cheese, sprinkle a little extra on top after shredding the beef and let it melt for a few minutes before serving. This adds a fresh, gooey element.

Variations

Spicy Chipotle Version: Stir 2 chipotle peppers in adobo sauce, minced, into the salsa before adding to the slow cooker. This adds a smoky, spicy kick that pairs perfectly with the beef and cheese.
Chicken Option: Replace the beef chuck with 2 pounds of boneless, skinless chicken thighs. Cook on low for 6-7 hours until the chicken is tender and shreds easily. Ensure the internal temperature reaches 165°F (74°C).
Veggie-Packed Version: Add 1 diced bell pepper and 1 diced zucchini along with the beans and corn. This adds extra color and nutrition without overwhelming the dish.
Smoky Adobo Twist: Mix 1 tablespoon of adobo seasoning or smoked paprika into the salsa for a deeper smoky flavor. This complements the fire-roasted corn and adds a rich, savory note.

Storage and make-ahead

Fridge: Store in an airtight container in the refrigerator for up to 4 days. Reheat gently with a splash of water or broth to maintain moisture.
Freezer: Freeze in a freezer-safe container for up to 3 months. Thaw overnight in the refrigerator before reheating.
Reheat: Reheat on the stovetop over medium heat, stirring occasionally, until heated through. Add a little broth if needed to loosen the sauce.

Store leftover barbacoa in an airtight container in the refrigerator for up to 4 days. The flavors will continue to meld, making it even more delicious the next day.

When reheating, add a splash of water or broth to loosen the sauce, and microwave or warm on the stovetop until heated through. The cheese may lose its blistered texture, but the dish remains comforting and satisfying.

This recipe is perfect for meal prep. You can assemble the raw ingredients in the slow cooker insert the night before, cover, and refrigerate. In the morning, simply place the insert into the slow cooker and set it to cook.

If you're preparing it for a party, cook it a day ahead, then reheat gently before serving. The flavors deepen as it sits, making it even better the second day.

Serving ideas

Serve the barbacoa over steamed Spanish rice for a hearty meal. The rice soaks up the rich sauce, and the tender beef and melted cheese create a satisfying bite.

Alternatively, spoon it into warm corn or flour tortillas for tacos, and top with fresh cilantro, diced onions, and a squeeze of lime. The dish is versatile and works well in burrito bowls, nachos, or stuffed peppers.

For a lighter option, serve the barbacoa on a bed of crisp lettuce with avocado slices and a dollop of sour cream. The smoky flavors pair beautifully with cool, creamy toppings.

You can also use it as a filling for quesadillas or enchiladas. Leftovers are great for breakfast—try it in a breakfast burrito with scrambled eggs. No matter how you serve it, this dish is sure to please.

Frequently asked questions

Can this recipe be made ahead of time?

Yes, this recipe is ideal for making ahead. Assemble the raw ingredients in the slow cooker insert, cover, and refrigerate overnight. In the morning, place the insert in the slow cooker and cook as directed. The dish also reheats well, so you can cook it a day in advance and reheat before serving.

What can be used instead of Oaxaca cheese?

If Oaxaca cheese is unavailable, use mozzarella, Monterey Jack, or a Mexican blend cheese. These cheeses melt well and have a mild, creamy flavor that complements the other ingredients. For a stronger flavor, try a smoked cheese like smoked Gouda.

How long does the beef need to cook?

Cook the beef on low for 8 to 10 hours, or on high for 4 to 5 hours. The beef is done when it reaches an internal temperature of 145°F (63°C) and shreds easily with a fork. Cooking low and slow yields the most tender results.

Can this dish be frozen?

Absolutely. Let the barbacoa cool completely, then transfer to a freezer-safe container. It can be frozen for up to 3 months. Thaw overnight in the refrigerator and reheat gently on the stovetop or in the microwave. The flavors remain delicious after freezing.

Is it necessary to rinse the black beans?

Rinsing the canned black beans removes excess sodium and the starchy liquid they are packed in. This helps control the saltiness of the final dish and gives a cleaner flavor. If using dried beans, cook them separately and add at the same time.

Prep 10 minCook 8 hTotal 8 h 10 minServes 8

Ingredients

2 1/2 lb beef chuck cubes
1 can (15 oz) black beans, rinsed
1 cup fire-roasted corn kernels
1 1/2 cups chunky roasted red tomato salsa
2 cups shredded Oaxaca cheese
1 cup shredded Mexican four-cheese blend

Instructions

Place the beef chuck cubes in the bottom of a 7-quart slow cooker. Spread them evenly. Add the rinsed black beans, fire-roasted corn, and chunky salsa over the beef. Do not stir; just pour them on top to create layers.
Sprinkle the shredded Oaxaca cheese and the Mexican four-cheese blend evenly over the top of the mixture. Do not stir. Cover the slow cooker with the lid.
Set the slow cooker to low and cook for 8 to 10 hours, until the beef is fork-tender and easily shreds. Avoid opening the lid during cooking to maintain heat and moisture. Let it rest for 3 minutes before slicing.
Once the beef is cooked through and reaches an internal temperature of 145°F (63°C), use two forks to shred the beef directly in the slow cooker. Stir the shredded beef into the beans, corn, and salsa mixture. Let it rest for 3 minutes before slicing.
Serve the barbacoa over steamed Spanish rice or in warm tortillas. Top with extra cheese, if desired. The dish is rich, smoky, and satisfying.
