Chicken-Bacon Smash Burgers

The chicken burgers from Ali Slagle’s cookbook I Dream of Dinner (So You Don’t Have To) have a little secret—they’re cooked in bacon fat, which adds flavor and moisture to the ground meat. And that’s not all: The chicken meatballs are smashed into a thin layer and topped with thinly sliced onion and jalapeño, yielding browned, juicy burgers juxtaposed with the sweetness and heat of the charred vegetables. Layer it all onto a toasty bun with the crispy bacon and as much ketchup as you please, then wonder how only a handful of ingredients brought such big flavor.
