1. Oven Baked Zucchini Slices (Yield: 4 Servings)
Ingredients
- 2 medium zucchini, sliced into 1/4 to 1/2-inch rounds
- 1 tablespoon olive oil
- Salt and pepper, to taste
- 1 cup freshly grated parmesan (pre-shredded is also fine)
Instructions
Preheat your oven to 425°F (220°C). Line a large baking sheet with parchment paper or lightly coat it with cooking spray to help prevent sticking and make cleanup easier.
Wash the zucchini thoroughly under cool running water and pat them dry with paper towels. Trim off both ends and slice the zucchini into rounds that are approximately 1/4 to 1/2 inch thick. Try to keep the slices as uniform as possible so they cook evenly.
Place the zucchini slices in a large mixing bowl. Drizzle the olive oil over the zucchini and gently toss until each slice is lightly coated. The oil helps the zucchini roast evenly while encouraging the parmesan cheese to brown nicely in the oven.
Arrange the zucchini slices in a single layer on the prepared baking sheet. Avoid overlapping the slices because crowded vegetables can steam instead of bake. Leave a small amount of space between each piece to promote even cooking.
Sprinkle the zucchini generously with salt and pepper according to your taste preferences. Seasoning the zucchini before baking helps bring out its natural flavor.
Evenly distribute the grated parmesan cheese over the tops of the zucchini slices. Try to cover each slice with a layer of cheese. The parmesan will melt during baking and create a delicious golden topping.
Place the baking sheet in the preheated oven and bake for 15 to 20 minutes. The exact cooking time may vary depending on the thickness of the zucchini slices and your oven. The zucchini should become tender while the parmesan begins to turn lightly golden.
For additional browning, switch the oven to broil during the final 1 to 2 minutes of cooking. Watch carefully during this step because parmesan cheese can brown quickly.
Remove the baking sheet from the oven and allow the zucchini to cool for a few minutes. This brief resting period helps the cheese set slightly and makes the slices easier to serve.
Transfer the oven baked zucchini slices to a serving platter and serve immediately while warm. They make an excellent side dish for chicken, fish, steak, pasta, or sandwiches.

2. Tips for Perfect Oven Baked Zucchini Slices
Choose firm zucchini with smooth skin and no soft spots. Fresh zucchini provides the best texture and flavor after baking.
Slice the zucchini into pieces of similar thickness to ensure even cooking. Uneven slices may result in some pieces becoming overcooked while others remain too firm.
Use freshly grated parmesan when possible. Freshly grated cheese often melts more evenly and creates a richer flavor than packaged varieties.
Do not overcrowd the baking sheet. Proper spacing allows hot air to circulate around the zucchini, helping it bake rather than steam.
If your zucchini seems particularly moist, gently pat the slices dry before adding oil and seasoning. Removing excess moisture can improve the final texture.
For extra flavor, add a pinch of garlic powder, Italian seasoning, or paprika along with the salt and pepper.
Serve the zucchini immediately after baking for the best texture and appearance.
