Push the onion and garlic mixture to the coolest part of your pan. Add the ground beef to the exposed surface, spreading it out evenly.• 2 pounds ground beef Cook the beef undisturbed for about 5 minutes, until the bottom develops a deep brown sear. Resist the urge to break it up—allowing the beef to sear undisturbed builds major flavor.
While the beef is searing, measure the spices into a small bowl and open the canned ingredients.
Once the bottom of the beef is a deep brown color, flip the beef in large chunks so the uncooked side contacts the pan. Cook undisturbed for another 4–5 minutes, until deeply browned.
While the beef sears, preheat the oven to 325°F and mince the chipotle pepper.
Reduce the heat to medium and break the beef into smaller pieces, allowing any remaining pink spots to cook and the fat to fully render.
Assess the amount of rendered fat. If there are visible pools of bubbling fat, reduce the heat to low and spoon off excess fat into a small bowl (see Notes). Leave a small amount for richness.
Stir the beef together with the onions and garlic, then push everything to the side. Set heat to medium.
