If time allows, refrigerate the mixture for a minimum of four hours (or as long as a few days).
Remove from refrigerator and press the mixture down to form a flat surface, then slice the mixture like a cake into eight equal portions.
Form the mixture into 8 patties and place on a parchment covered baking sheet.
Bake at 350 degrees for 30 minutes, flipping over halfway through.
Serve on a toasted bun with sprouts, cucumbers, red onions, tomato, lettuce, mayo, or whatever other toppings you want!
For a vegan / egg free version, use flax or chia egg substitutes.
For easy weeknight meals, make extra burgers and wrap tightly in plastic wrap and freeze for later.
Don't have quick cooking oats? Rolled/old fashioned oats will also work, but I suggest giving the mixture more time in the refrigerator so the oats absorb more of the liquid. Otherwise, your patties may fall apart or be hard to form. Bread crumbs can also be used.
