Step 1

Preheat oven to 425°F. Line 2 large baking sheets with parchment paper.

Step 2

Line a colander with paper towels or a clean kitchen towel. Add grated potatoes, carrots, and onion; let drain, then squeeze out any liquid with your hands.

Step 3

In a large bowl, mix egg, flour, zest, salt, and pepper; add potato mixture and stir to combine.

Step 4

Drop potato mixture in mounds, using a 1/4 cup measure, onto prepared baking sheets. Press each one slightly to flatten into a 3-inch round (about 1/4-inch thick).

Step 5

Coat tops of latkes with cooking spray; bake for 15 minutes. Rotate pans in oven and bake until browned and crispy, about 15 minutes more.

Step 6

Serving size: 1 latke (pancake)
