Chopped Beef Barbacoa Sandwich

Pro tips

• Chop the barbacoa into bite-sized pieces rather than shredding—it distributes better on the bun and easier to eat.
• Warm the chopped beef just before assembly to ensure it's hot enough to warm the cheese sauce and bun slightly.
• Toast the potato bun lightly to add structural integrity and prevent sogginess from the cheese sauce and chimichurri.
• Apply the cheese sauce while the beef is still warm so it melts slightly and adheres to the meat.

Substitutions

• Potato bun → brioche bun or ciabatta roll (adjust toasting time)
• Chimichurri barbecue sauce → traditional BBQ sauce mixed with fresh cilantro and lime juice
• House-made cheese sauce → melted cheddar or queso fundido (warmed separately)

Storage & make-ahead

Store cooked barbacoa in an airtight container in the refrigerator for up to 4 days; reheat gently in a skillet or slow cooker with a splash of broth. Assemble sandwiches fresh to preserve bun texture.

How do you make beef barbacoa tender?

Slow-cook beef low and slow—typically 6-8 hours in a slow cooker or oven at low temperature—until the meat shreds easily with a fork.

Can you make this sandwich ahead of time?

Cook the barbacoa ahead and refrigerate up to 4 days. Warm before assembling. Assemble sandwiches fresh to keep the bun from getting soggy.

What's the best potato bun for this sandwich?

Use a sturdy, slightly sweet potato bun that can hold the weight of the beef and sauce without falling apart. Brioche works as a substitute.

Can you substitute the chimichurri barbecue sauce?

Yes—use a traditional barbecue sauce, or mix chimichurri herbs into your favorite BBQ sauce for a lighter herbaceous flavor.

How much beef barbacoa per sandwich?

Plan for 5-6 oz of chopped slow-cooked barbacoa per sandwich for a generous, satisfying portion.
