Follow these detailed steps carefully to ensure your zucchini fritters are perfectly crispy on the outside and tender on the inside every time. The process is straightforward but relies on one key technique: removing excess water.

Step 1: Prepare the Zucchini (The Most Important Step!)

1. Grate the Zucchini: Wash and trim the ends off the zucchini. Using the large holes of a box grater, grate the zucchini into a large bowl. There is no need to peel the zucchini, as the skin contains nutrients and adds nice color.
2. Salt and Wait: Sprinkle the 1 teaspoon of sea salt over the grated zucchini and toss to combine thoroughly. Transfer the salted zucchini to a colander set over the sink or a bowl. Let it sit for 10-15 minutes. You will see water begin to bead and drip from the zucchini; this is exactly what you want. The salt is drawing out the excess moisture.

Step 2: Make the Dill Yogurt Sauce

1. Combine Ingredients: While the zucchini is resting, prepare the sauce. In a small bowl, combine the Greek yogurt, chopped fresh dill, fresh lemon juice, and minced garlic.
2. Mix and Chill: Stir everything together until it’s smooth and well-incorporated. Season with a pinch of salt and pepper to your liking. Cover the bowl and place it in the refrigerator to chill while you make the fritters. This allows the flavors to meld together beautifully.

Step 3: Squeeze the Zucchini Dry

1. 1. Squeeze Out Water: After the zucchini has rested, it’s time to squeeze. Grab a handful of the grated zucchini and squeeze it tightly over the sink to release as much liquid as possible. Alternatively, you can place the zucchini in the center of a clean kitchen towel (cheesecloth works perfectly too), gather the ends, and twist and squeeze until no more water comes out.
   2. Measure for Success: You should be left with approximately 1.5 cups of dry, compacted zucchini. Getting rid of this water is the single most critical step to prevent soggy fritters.

Step 4: Mix the Fritter Batter

1. Combine Dry Ingredients: In a large mixing bowl, place your squeezed, dry zucchini. Add the all-purpose flour, panko breadcrumbs, grated Parmesan cheese, finely sliced green onions, minced garlic, and black pepper.
2. Mix Gently: Use a fork or your hands to toss these ingredients together until the zucchini is evenly coated.
3. Add the Egg: Add the lightly beaten egg to the bowl. Mix gently until everything is just combined. Be careful not to overmix the batter, as this can lead to tough fritters. The mixture should be thick and hold its shape.

Step 5: Cook the Fritters

1. Heat the Oil: Place a large non-stick skillet or cast-iron pan over medium heat. Add enough olive or avocado oil to generously coat the bottom of the pan (about 2-3 tablespoons per batch). Allow the oil to get hot; you can test it by dropping a tiny bit of batter in—it should sizzle immediately.
2. Form and Fry: Scoop heaping tablespoons of the batter and gently drop them into the hot oil, carefully flattening them slightly with the back of the spoon to form small patties about 2-3 inches in diameter. Don’t overcrowd the pan; cook in batches of 4-5 fritters at a time to ensure they cook evenly and get crispy.
3. Cook to Golden Brown: Fry the fritters for 3-4 minutes on the first side, until the edges are deep golden brown and crispy. Use a thin spatula to carefully flip them over.
4. Finish Cooking: Cook for another 3-4 minutes on the second side until equally golden brown and cooked through.
5. Drain on a Wire Rack: As the fritters are done, transfer them from the pan to a wire cooling rack set over a baking sheet. Do not drain them on paper towels, as this can trap steam and make the bottoms soggy. The wire rack allows air to circulate, keeping them crispy.
6. Repeat: Add more oil to the pan as needed and repeat the process with the remaining batter. Sprinkle the hot fritters with a tiny pinch of extra sea salt, if desired.

Step 6: Serve Immediately

Serve the warm, crispy zucchini fritters immediately with the chilled dill yogurt sauce on the side for dipping.
