Mashed Kohlrabi and Red Potato Bake

1 large kohlrabi bulb, peeled and cut into cubes

6 small red potatoes

2 teaspoons grated garlic scape

½ cup shredded mozzarella cheese

Preheat oven to 325 degrees F (165 degrees C).

Bring a small pot of lightly salted water to a boil; cook kohlrabi cubes in boiling water until soft, about 15 minutes; drain.

Cook red potatoes in microwave oven until soft, about 10 minutes.

Beat kohlrabi, potatoes, and garlic scape together in a bowl with an electric hand mixer until smooth; transfer to a 1-quart casserole dish and top with mozzarella cheese.

Bake in the preheated oven until the cheese begins to brown, about 30 minutes.
