If you are in a hurry, or forgot to thaw the frozen burger patties, you can bake them from frozen in the oven.  This is a better alternative than grilling or cooking on the stovetop when cooking burgers-from-frozen because baking the burgers cooks them more evenly. To bake frozen patties: 1. Preheat oven to 350 degrees F. 2. Lightly grease a baking sheet with sides. 3. Line the frozen hamburger patties on the sheet without touching. 4. Cover the sheet loosely with aluminum foil by creating a “tent” and peaking the foil in the center and sealing on the sides. 5. Bake for 30-60 minutes depending on thickness of burger and how well done you like them.
