1
Slice the tempeh into patties. Tempeh normally comes in a cube shape, so it's easiest to slice it into squares. Round off the corners if you prefer your burgers to have a round shape. Each slice should be 1/2 inch thick.
2
Place the tempeh pieces in a baking pan. Use a nine or twelve-inch pan, depending on which size is large enough to hold all the pieces in a single layer.
3
Preheat the oven to 375 °F (191 °C).[3] 4
Mix up the marinade. In a small bow, whisk the soy sauce, olive oil, brown sugar, and thyme.
5
Pour the marinade over the tempeh slices. Make sure each slice gets covered in plenty of marinade.
6
Bake the tempeh for 30 minutes. During this time the marinade will begin to flavor and soften the tempeh.
7
Flip the tempeh and bake for another 30 minutes. By the time you are finished baking the tempeh, all the marinade should be absorbed. If you still see liquid in the pan, keep baking the tempeh until the liquid is absorbed.
8
Remove the pan from the oven. Use a spatula to loosen the tempeh burgers from the pan.
9
Serve the tempeh burgers. Place them on buns and serve with lettuce, tomatoes, and cheese.
