- 2–3 tbsp buttermilk (to thin)
- 1 tbsp finely chopped fresh dill
- 1 tbsp finely chopped fresh chives
- 1 tbsp finely chopped fresh parsley
- 1/2 tsp garlic powder
- 1/2 tsp onion powder
- 1 tsp fresh lemon juice
- 1/4 tsp kosher salt, 1/8 tsp black pepper
Lemony Aioli (Optional, Makes About 1/2 Cup)
- 1/2 cup good-quality mayonnaise
- 1 small garlic clove, very finely grated
- 2 tsp fresh lemon juice
- 1/2 tsp finely grated lemon zest
- 1 tbsp extra-virgin olive oil
- Pinch kosher salt and freshly ground black pepper

Step-by-Step Instructions
Step 1: Heat the oven and prep the pan
Place a rimmed baking sheet on the center rack and heat the oven to 425°F. If you have a wire rack that fits inside the sheet pan, set it in now; elevating the fries helps hot air circulate so both sides crisp. If you do not have a rack, line the hot sheet with parchment just before baking.
Step 2: Cut and dry the zucchini
Trim ends. Slice each zucchini into 3-inch long planks about 1/2 inch thick, then into fries about 1/2 inch wide. Pat the pieces very dry with paper towels—this is key to a crunchy coating.
Step 3: Set up the breading stations
In Bowl 1, whisk the cornstarch with 1/2 tsp kosher salt and 1/2 tsp black pepper. In Bowl 2, beat the eggs with 1 tbsp milk. In Bowl 3, combine panko, Parmesan, garlic powder, 1/2 tsp black pepper, 1/4 tsp kosher salt, smoked paprika, cayenne, and lemon zest. Stir well so the spices and zest are evenly distributed.
Step 4: Bread the zucchini fries
Working a handful at a time, toss fries in the cornstarch mixture to lightly coat, shaking off excess. Dip into the egg wash, letting extra drip back into the bowl. Press firmly into the panko-Parmesan mixture to coat on all sides. Arrange coated fries on the prepared rack with a bit of space between each. Mist generously with olive oil spray (or drizzle/smear about 2 tsp olive oil over the batch).
Step 5: Bake until crisp and golden
Bake 18–22 minutes, rotating the pan halfway through. The fries are done when the crust is deep golden with crunchy panko peaks and melted Parmesan edges. If you want extra color, broil for 1–2 minutes at the end, watching closely. Sprinkle with a pinch of kosher salt while hot.
Step 6: Stir together the cool ranch
In a small bowl, whisk sour cream, mayonnaise, and 2 tbsp buttermilk. Add dill, chives, parsley, garlic powder, onion powder, lemon juice, salt, and pepper. Adjust thickness with an extra tablespoon of buttermilk if needed. Chill until serving.
Step 7: Whisk the lemony aioli
In another bowl, whisk mayonnaise, grated garlic, lemon juice, lemon zest, and olive oil until glossy and smooth. Season with a pinch of salt and a few grinds of pepper. For a thinner drizzle, whisk in 1–2 tsp water.
Step 8: Serve
Transfer hot zucchini fries to a platter. Finish with a light shower of Parmesan, a few cracks of black pepper, and a whisper of lemon zest. Serve immediately with ramekins of cool ranch and lemony aioli for dipping.
Pro Tips
- Use a wire rack over a hot sheet pan for maximum airflow and crunch on all sides.
- Press the panko firmly onto each fry so the coating adheres and bakes into a craggy crust.
- Keep the fries similar in size (1/2 inch thick) for even cooking and the best texture.
- Do not skip drying the zucchini—excess moisture softens the crust.
- Convection ovens run hotter; if using convection, try 415°F and check for doneness at 15–17 minutes.
Variations
- Herby Parmesan: Swap smoked paprika and cayenne for 1 tsp Italian seasoning and 1 tsp finely chopped rosemary.
- Everything Bagel: Replace garlic powder and paprika with 1 tbsp everything bagel seasoning; reduce added salt by half.
- Gluten-Free: Use gluten-free panko; all other ingredients are naturally gluten-free.
Storage & Make-Ahead
Fries are best fresh. To make ahead, bread the fries up to 4 hours in advance; refrigerate uncovered on a rack. Bake just before serving. Leftovers: refrigerate in an airtight container up to 2 days. Re-crisp at 425°F on a rack for 8–10 minutes. Dips can be made up to 3 days ahead; cover and refrigerate.
