In a large bowl, combine potato, parsnip, egg, matzo meal, thyme and garlic powder. Stir until all ingredients are combined.

In a large skillet, heat oil over medium high heat. Scoop 1/4 cup of batter and carefully place in oil. Flatten to about 1/2-inch thick with a spatula. Repeat to form 4 more latkes in your pan, being careful not to crowd the pan and cook for 4 to 6 minutes. Flip and cook 4 to 6 minutes more or until golden brown on both sides.

Transfer to a paper towel lined baking sheet and repeat with remaining batter.

Sprinkle with salt and serve immediately.
