Gather all ingredients and prepare your workspace; dice the onions and mince the garlic.

In a large bowl, combine ground beef, birria seasoning, diced onions, minced garlic, salt, and pepper; mix thoroughly using your hands.

Shape the mixture into four patties slightly larger than the buns.

Preheat your smoker to 225°F (107°C); if unavailable, use indirect heat on a grill.

Place patties in the smoker and cook for about one hour until they reach an internal temperature of 160°F (71°C).

During the last five minutes of smoking, add cheese slices to melt and toast burger buns on the grill until golden brown. Assemble with toppings and serve hot.
