Shred the Zucchini: Using a box grater or food processor, shred your medium zucchini into a large mixing bowl, aiming for about 4 cups total.
Remove Excess Moisture: Transfer the shredded zucchini to a clean kitchen towel and squeeze firmly over the sink to remove as much liquid as possible, about 2 to 3 minutes of squeezing. This step is crucial for crispy fritters, so don't skip it.
Return to Bowl: Place the drained zucchini back into your mixing bowl and set aside.
Combine Ingredients: Add the beaten eggs, shredded parmesan, almond flour, garlic salt, and black pepper to the bowl with the zucchini and stir until everything is well combined into a cohesive mixture.
Let It Rest: Allow the mixture to sit for 5 minutes so the almond flour can absorb any remaining moisture and help bind the mixture together.
Form Patties: Using a sturdy spoon or your hands, form the mixture into 12 to 16 small patties, each about 2 inches wide and 1/2 inch thick, placing them on a clean plate.
Heat the Oil: Place a large skillet over medium-high heat and add the olive oil, allowing it to shimmer for about 1 minute until it's fully heated.
Fry the Fritters: Carefully place the zucchini patties in the hot skillet, working in batches if needed to avoid overcrowding, and cook for 3 to 4 minutes per side until golden brown and crispy.
Drain Excess Oil: Transfer the cooked fritters to a paper towel-lined plate to drain any excess oil, keeping finished batches warm while you fry the remaining patties.
