In a resealable plastic bag, combine the flour, paprika, cayenne, parsley, salt, and pepper.
Shake to mix evenly.
In a large frying pan or cast-iron skillet, heat the vegetable oil to a depth of about ¼ inch (6 mm) over high heat.
The temperature should be 350° to 375°F (180° to 190°C).
Test by dropping in a bit of flour—if it sizzles, the oil is ready.
Add about 10 zucchini slices at a time to the bag with the flour mixture.
Shake to coat thoroughly.
Place the coated zucchini slices into the hot oil, making sure not to overcrowd the pan.
Fry for 1 to 2 minutes per side until lightly golden.
Remove the zucchini slices and place them on a plate lined with kitchen or paper towels to drain excess oil.
Add the slices back into the flour mixture for a second coating.
Heat a little more oil in the pan, ensuring it reaches the correct temperature.
Fry the zucchini slices a second time, cooking until they achieve a golden brown color on both sides.
Drain again on the lined plate.
Repeat with the remaining zucchini slices.
Serve hot with marinara sauce for dipping.
