Essential ingredients for making crispy and flavorful roasted zucchini slices, ready for preparation.

Fresh Zucchini (Medium-Sized for Even Slicing)

Choose firm zucchini with smooth skin. Medium-sized zucchini cook evenly and give the best flavor for roasted zucchini slices. Always choose those zucchinis with rich color and relatively small to medium size.

Olive Oil, Sea Salt, and Black Pepper

Olive oil adds richness and helps the slices get crispy. Sea salt and black pepper bring out the natural flavor of zucchini.

Optional: Garlic Powder or Fresh Minced Garlic

Garlic adds a warm, savory taste. Use garlic powder for a mild flavor or fresh minced garlic for a stronger kick.

Optional Toppings: Grated Parmesan or Italian Seasoning

Parmesan cheese gives a crispy, cheesy layer. Italian seasoning adds a blend of herbs that make roasted zucchini slices more aromatic.

Tools: Sharp Knife, Baking Sheet, Parchment Paper

A sharp knife ensures even slices. A baking sheet and parchment paper help with easy roasting and cleanup.

How to Make Roasted Zucchini Slices in the Oven

Step 1: Preheat Oven to 400°F (200°C) and Slice Zucchini Evenly

Set your oven to 400°F (200°C). Slice the zucchini into even rounds so they cook at the same rate.

Step 2: Toss Slices in Olive Oil and Desired Seasonings

Place the zucchini slices in a bowl. Add olive oil, sea salt, black pepper, and your favorite spices. Mix well so each slice gets coated.

Step 3: Arrange on Parchment-Lined Baking Sheet in a Single Layer

Line a baking sheet with parchment paper. Lay the zucchini slices flat without overlapping. This helps them roast evenly.

Step 4: Roast for 20–25 Minutes, Flipping Halfway for Even Browning

Place the tray in the oven. Roast for 10–12 minutes, flip the slices, and roast for another 10–12 minutes until golden and tender.

Optional: Add Parmesan in the Last 5 Minutes for Crispy Tops

Sprinkle grated Parmesan on top during the final 5 minutes of roasting. This creates a crispy, cheesy finish.

Tips for Perfectly Roasted Zucchini

Don’t Overcrowd the Pan – Use Two Sheets if Needed

Give each slice enough space on the baking sheet. Overcrowding traps steam and makes roasted zucchini slices soft instead of crispy.

Pat Slices Dry to Avoid Sogginess

After washing, dry the zucchini slices well with a paper towel. Removing excess water helps them roast better and get a golden edge.

Play with Spices Like Smoked Paprika or Chili Flakes

Add flavor by trying different spices. Smoked paprika adds depth, while chili flakes give a spicy kick to your roasted zucchini slices.

Add Cheese at the End to Prevent Burning

If you love cheesy zucchini, sprinkle Parmesan or other cheese during the last few minutes of roasting. This keeps it crispy without burning.

Use a Wire Rack for Even Crisping (Optional)

Place the zucchini slices on a wire rack set over a baking sheet. This allows heat to circulate for extra-crispy results.
