Make Mozzarella Sticks Recipe: double-coated, crispy mozzarella sticks ready to fry and dip.
If using a block of low-moisture whole-milk mozzarella, slice it into uniform 1/2-inch (1.25 cm) planks and then cut those planks into 3-inch (7.5 cm) sticks so you have ~16–18 evenly sized pieces; if using string cheese, simply unwrap and leave the sticks whole. Work cleanly and pat each piece dry with a paper towel so the surface is slightly tacky but not wet — that small dryness helps the first flour layer cling evenly. Keep the cut sticks corralled on parchment while you build the breading station.
In a shallow matte grey ceramic bowl, combine the all-purpose flour with kosher salt, garlic powder, onion powder, dried oregano, dried basil and black pepper; stir with a fork until the dry spices are evenly distributed and you see tiny flecks of herb throughout the white powder. Arrange three shallow vessels in a line: the matte grey bowl of seasoned flour at the left, a shallow white porcelain dish for the egg wash in the center, and a pale sage ceramic bowl reserved for the breadcrumb mixture on the right — this clean station keeps the workflow fluid and makes double-dipping simple.

In the white porcelain dish, whisk the eggs with the whole milk, water and a pinch of kosher salt until completely homogeneous and glossy with no streaks of white; rest the whisk on the rim so a few droplets cling, signaling readiness. In the pale sage ceramic bowl, combine Italian-style breadcrumbs, panko, finely grated Parmesan, garlic and onion powders and a light pinch of kosher salt; fold until the Parmesan melts into the crumbs and you can see coarse panko flakes and fine cheesy granules together — that contrast is what creates the ideal crunchy crust.

Working in small batches, roll each mozzarella stick through the seasoned flour in the matte grey bowl, pressing gently so the ends and edges are fully dusted; shake off excess so the flour layer is even and thin. Transfer directly to the egg wash, rolling and spooning until every face is moistened, then press into the breadcrumb bowl so crumbs adhere and form a coarse, textured shell. Keep the same three bowls visible and consistent as you work — the fork, whisk and a small spoon remain as the active tools perched nearby.

For a protective, crack-resistant crust, immediately repeat the egg dip and breadcrumb press: a light second egg coat followed by a firm second crumb press so the surface is uniformly thick and rugged with panko peaks and Parmesan speckles. Place each finished stick single-file on a parchment-lined baking sheet, none touching, creating a disciplined row of heavily coated sticks ready to firm up in the cold. Cover the tray and transfer to the freezer until solid — this full freeze is the insurance against cheesy leaks during frying.
About 15 minutes before you plan to cook, bring oil to temperature off-screen; when ready, fry a single frozen stick as a test until the crust is deep golden and you see the slightest softening at the ends without any cheese escape. Then fry 4–6 frozen sticks at a time, turning gently every 30 seconds and keeping the exterior an even, deep-golden brown. Work systematically so the oil recovers between batches and the crust finishes crisp while the interior becomes molten.

Lift finished sticks onto a wire rack set over a baking sheet or a paper-towel–lined plate to drain; while still hot, scatter a light pinch of kosher salt to heighten flavor. Warm marinara separately in a small saucepan until gently simmering, then transfer to a small white ramekin for dipping. Transfer the hot mozzarella sticks to a low, rectangular matte-black platter in a single, attractive stack, sprinkle with finely chopped parsley for brightness, and set the warm marinara ramekin at one end for easy dipping.
To make ahead, freeze the breaded uncooked sticks on the tray until solid (about 2 hours), then move to a freezer-safe bag for up to 1 month; fry directly from frozen at 350°F (175°C) for 2–2 1/2 minutes. To re-crisp previously fried sticks, set them on a wire rack over a baking sheet and bake at 375°F (190°C) for 6–8 minutes until hot and crunchy again; watch closely so the cheese doesn’t escape.
