Brown the ground beef in a large skillet over medium heat until almost fully cooked. Sprinkle in taco seasoning, garlic powder, and onion powder. Add a splash (around 60 ml) of water, then simmer until beef is well-browned and fragrant, about 6 minutes. Drain excess fat.
02 -
Heat the cooked Mexican rice until just hot. If using, warm black or refried beans until thick but spreadable to avoid soggy burritos.
03 -
Lay each tortilla flat. Spread 1/4 of the sour cream in a line down the center. Add an even layer of warm rice, then spoon on seasoned beef. Sprinkle generously with cheddar and Monterey Jack cheeses. Add beans if using.
04 -
Fold in both long sides of the tortilla, then roll tightly from the bottom up. Place seam-side down and press lightly to maintain shape.
05 -
Lightly spread softened butter on one side of each rolled burrito.
06 -
Preheat a large dry skillet over medium heat. Sprinkle a handful of shredded cheese into a rectangle on the pan. Place the burrito, buttered side down and seam-side down, directly over the cheese. Cook until the cheese is crisp and golden, about 2–3 minutes.
07 -
Add more cheese to the pan if desired. Carefully flip the burrito and grill the opposite side until both surfaces are deeply golden and crunchy.
08 -
Remove from the pan. Let burrito rest for 1 minute before slicing in half for clean edges and optimal melty filling.
