Instructions for Sourdough Zucchini Fritter Recipe

STEP 1: In a large mixing bowl, grate the zucchini through the large holes of a box grater. Sprinkle the grated zucchini with 1 teaspoon of salt. Let sit for 10 minutes to draw out excess moisture.

STEP 2: Then use a clean towel or cheesecloth, and place the shredded zucchini in it to squeeze out as much excess water as possible.

STEP 3: In a large bowl, whisk the egg. Stir in the sourdough discard, flour, Parmesan (if using), green onions, garlic, pepper, lemon zest, flour, and baking powder.

STEP 4: Add the drained zucchini and mix until well combined.

STEP 4: Heat 1–2 tablespoons of oil in a skillet over medium-high heat. Scoop about 2 tablespoons of batter per fritter into the hot pan, flattening slightly. Cook for 3–5 minutes per side, or until golden and crisp.

STEP 5: Drain on a paper towel or cooling rack. Serve warm with sour cream, Greek yogurt, or your favorite dipping sauce.
