Ingredients You’ll Need

The beauty of Zucchini Parmesan lies in its short ingredient list, but don’t let that fool you—each item carries real importance for taste, crunch, and gooey satisfaction. Gather these few key players, and you’re guaranteed layers of savory, fresh flavor.

• Zucchini: Look for medium, firm zucchini for the best texture—no need to peel unless you have giant ones!
• Egg Whites: Beaten with garlic powder, these help breading stick and create a light, airy coating without heaviness.
• Garlic Powder: Adds a mellow, aromatic kick right into the breading for extra flavor in every bite.
• Marinara Sauce: Go for your favorite jar or homemade, as it will soak into the layers and keep everything moist.
• Mozzarella Cheese: Opt for whole-milk or part-skim—but don’t skimp, this brings the gooey, cheesy pull we all love.
• Vegetable Oil: If choosing to fry, this delivers that iconic golden crunch; skip if opting for the Baking Method: Arrange on a lightly greased baking sheet and spray each side with cooking spray.
• Flour: The first step in getting the zucchini super crispy—lightly dusting helps the coating adhere.
• Italian Breadcrumbs: Pack in garlicky, herby flavor and a super crisp finish.
• Parmesan Cheese: Grated in the breading for sharp, salty complexity that complements the mozzarella.
• Kosher Salt & Black Pepper: Balances moisture and brings all the flavors together. Don’t skip the pre-salting!

How to Make Baking Method: Arrange on a lightly greased baking sheet and spray each side with cooking spray

Step 1: Prep the Zucchini

Begin by giving your zucchini a good rinse and then thoroughly pat dry. Slice them into ¼-inch rounds for just the right bite—thick enough to hold up under the cheese, but thin enough to turn deliciously crisp. Lay the slices over paper towels, sprinkle both sides lightly with salt, top with additional towels, and let them rest for at least 30 minutes (or up to an hour). This key step draws out excess moisture so you never end up with soggy layers—trust me, it’s worth the wait!

Step 2: Mix the Breading and Egg Wash

In a bowl, whisk the egg whites with garlic powder until they’re nice and frothy—this froth will ensure the breading clings perfectly. In another small bowl, toss the flour, Italian breadcrumbs, grated Parmesan, salt, and pepper. This aromatic breading mix will give you that gorgeous, flavorful crust on every piece.

Step 3: Dredge the Zucchini

Dip each zucchini round first into the egg mixture, letting excess drip off, then into the breading. Don’t be shy with the coating! Give each slice a little pat with a spoon to help it stick. Flip and repeat so both sides are fully coated. If you find the zucchini getting damp again, just dip them back in the breading before cooking for the crispiest possible finish.

Step 4: Cook the Zucchini—Baking, Air Frying, or Frying

You have options here! For a lighter, equally satisfying version, try the Baking Method: Arrange on a lightly greased baking sheet and spray each side with cooking spray. Bake at 400 degrees for 18 to 20 minutes, flipping once halfway through, until golden and crispy. If you have an air fryer, cook at 375 degrees for 8 minutes with the same cooking spray technique. For purists, fry in hot vegetable oil (350 degrees) for 2–3 minutes per side, letting the slices brown to perfection. Whichever you choose, let the cooked rounds cool on a rack for maximum crunch.

Step 5: Assemble and Bake

Preheat your oven to 400 degrees. Spread a thin layer of marinara sauce on the bottom of a 9×13-inch casserole dish, then top with a layer of zucchini rounds. Spoon more marinara over each slice and sprinkle generously with mozzarella cheese. Repeat the layers—sauce, zucchini, cheese—until everything is used up, making sure the final layer is a crown of gooey mozzarella. Bake, uncovered, for 20–25 minutes until bubbly and golden on top.

Garnishes

This Zucchini Parmesan is truly special with a few finishing touches. Sprinkle chopped fresh basil or parsley over the melted cheese for a burst of color and fresh aroma. If you’re feeling extra fancy, a light dusting of grated Parmesan right after baking elevates every bite with salty umami flavor.

Side Dishes

Classic pairings always win: serve alongside a tangle of spaghetti or penne tossed with olive oil and garlic. Crusty bread (especially Cheesy Garlic Bread!) is a must for mopping up every bit of sauce. If you want something lighter, a zippy arugula salad with a lemony vinaigrette is the perfect fresh balance to the cheesy richness.

Creative Ways to Present

Turn this casserole into individual stacks by layering rounds, sauce, and cheese into ramekins for a personal touch—so cute for dinner parties! Or, bake the zucchini rounds on their own using Baking Method: Arrange on a lightly greased baking sheet and spray each side with cooking spray, then serve as crispy appetizers with marinara for dipping. Stack a few slices between toasted ciabatta for an unforgettable veggie Parmesan sandwich.

Make Ahead and Storage

Storing Leftovers

Leftover Zucchini Parmesan keeps beautifully in the fridge for up to three days. Wait for it to cool to room temperature, then cover tightly or transfer to airtight containers. Be sure to layer parchment or wax paper between slices to help preserve their texture.

Freezing

For best results, use the Baking Method: Arrange on a lightly greased baking sheet and spray each side with cooking spray before freezing the individual zucchini rounds. After baking and cooling, freeze in a single layer until solid, then transfer to freezer bags. The assembled casserole can also be frozen, but bake unthawed for best results—the cheese may not be quite as gooey, but it will still hit the spot.

Reheating

Reheat straight from the fridge, covered, in a 350-degree oven until hot and bubbly (about 15–20 minutes). For extra crispy slices, give them a few minutes uncovered at the end or pop leftovers back under the broiler. Individual rounds, especially those baked using Baking Method: Arrange on a lightly greased baking sheet and spray each side with cooking spray, re-crisp well in a toaster oven, too.
