Bring a braiser or saucepan over medium high heat with 2-3″ of frying oil to 350F (or until glistening).
Generously dip and coat each stuffed zucchini blossom in the batter, then transfer to the hot olive oil.
Fry in small batches of 2-3 blossoms at a time until golden brown on all sides.
Then transfer with kitchen tongs to a paper towel lined plate or a wire rack to help drain excess oil.
Enjoy immediately with extra grated parmesan, lemon wedges, and flaky sea salt.
