How To Make Baked Parmesan Zucchini
This recipe comes together in four easy steps—let the oven finish the work.

- Step 1: Spread grated Parmesan evenly across a baking sheet.

- Step 2: Arrange overlapping, very thin zucchini slices on top of the Parmesan.

- Step 3: Season with freshly ground black pepper, Italian seasoning, and a drizzle of olive oil.
Tips and Tricks
- Use good-quality Parmesan and grate it yourself for the best texture and flavor.
- If you don’t like Parmesan, try cheddar, mozzarella, pecorino romano, manchego, or asiago. If using a milder or softer cheese, season it lightly with salt and pepper before topping with zucchini.
- Avoid very soft cheeses like cream cheese, goat cheese, or feta for this preparation— they won’t crisp the same way.
- Slice the zucchini very thinly (a mandoline gives the most even results).
- Lay zucchini in a single layer with slight overlaps for an attractive presentation and to maximize vegetable coverage.
- Serve these as part of a cheese board, as an appetizer, or as a simple side dish.

Storage and Reheating
- Cut baked Parmesan zucchini into single portions before storing.
- Keep leftovers in an airtight container in the refrigerator.
- Enjoy them at room temperature, straight from the fridge, or gently reheat in a toaster oven for a few minutes to restore some crispness.
Serving Suggestions
These Parmesan zucchini slices pair well with other appetizers. Try them alongside stuffed mushrooms, labneh balls, marinated cheese, or bite-sized savory snacks for a varied platter.

Description
These baked Parmesan zucchini slices are an easy, tasty snack or appetizer that’s low in carbs and full of flavor.
Ingredients
Units
Scale
- 1 large, medium zucchini, sliced very thinly with a mandoline.
- 2 cups grated parmesan cheese
- 2 tsp Italian seasoning
- Freshly ground black pepper, to taste
- 1 tbsp Extra virgin olive oil
Instructions
- Preheat oven to 400ºF.
- Spread the grated Parmesan to cover a 9×13-inch baking sheet. If using a disposable aluminum pan, line it with parchment paper.
- Using a mandoline, thinly slice the zucchini. If you don’t have a mandoline, use a sharp knife to slice as thinly as possible.
- Arrange the zucchini slices on top of the grated Parmesan, overlapping until the surface is covered.
- Season with black pepper, Italian seasoning, and a drizzle of olive oil.
- Bake for about 20 minutes, then let cool. Carefully lift the Parmesan zucchini from the sheet, cut into squares or rectangles, and serve warm or at room temperature.
Notes
- Shredded cheddar or mozzarella can be used instead of Parmesan; season with salt and pepper before topping with zucchini to compensate for milder cheeses.
- When using Parmesan, additional salt is usually unnecessary because the cheese provides enough seasoning.
