Grate your 2 zucchinis using the large holes on a box grater, then place them in a clean kitchen towel. Squeeze out as much liquid as you can — and I mean really squeeze hard. You'll be surprised how much water comes out. This step makes the difference between crispy fritters and soggy ones, so don't rush it.
Transfer your squeezed zucchini to a large bowl and add the grated onion, minced garlic, and chopped fresh herbs. Stir everything together until combined. The mixture should smell incredibly fresh at this point, which is honestly my favorite part. You're building flavor from the ground up here.
In a separate small bowl, whisk together your 2 eggs, then pour them into the zucchini mixture. Add your crumbled feta cheese and mix until everything is evenly distributed. The feta adds saltiness and helps bind everything together, plus it brings that Mediterranean flavor that makes people ask for your recipe.
In another bowl, combine the flour, baking powder, salt, and black pepper. Sprinkle this dry mixture over your wet ingredients and fold it in gently until just combined. Don't overmix or you'll end up with tough fritters instead of tender ones. A few small lumps are totally fine.
Heat your olive oil in a large skillet over medium heat for about 2 minutes. You'll know it's ready when a small drop of batter sizzles immediately — this usually takes about 2 minutes. While you're waiting, use a spoon or small ice cream scoop to portion your batter into 12 fritters.
Carefully place your fritters into the hot oil, flattening each one slightly with the back of your spoon. You want them about 1/2 inch thick so they cook through without burning. Fry for 3 to 4 minutes on the first side until golden and crispy, keeping an eye on them after minute 2.
Flip each zucchini fritter and cook for another 3 to 4 minutes until the second side is equally golden. Transfer to a paper towel-lined plate to drain excess oil. Serve warm or at room temperature — honestly both ways are amazing, though I personally think they taste best fresh from the pan.
