  4. Measure 14 to 12 cup of burger meat and shape into a patty. Place on baking sheet and repeat.
  5. Bake in oven for 25 to 30 minutes, or until top begins to get slightly golden. You can flip burgers halfway through cooking time if you want even caramelization on both sides.

These burgers are moist and juicy and have a savory flavor that comes from a secret ingredient: A hefty amount of mustard. Half a cup may seem like a lot of mustard, but it’s what makes these burgers outstanding. Using grated sweet potato instead of traditional flour or breadcrumbs adds extra fiber and nutrients.
