Let’s dive in.
How to Bake Sliced Zucchini in the Oven
Learning how to bake sliced zucchini is really about three things: drying the slices, seasoning them well, and giving them enough space on the pan.
Get those right, and baked sliced zucchini will become a regular in your rotation.
Here’s how the process works.
1. Preheat and Prep Your Pan
Start by preheating your oven to 425°F (220°C).
Line a baking sheet with parchment paper or lightly grease it so the zucchini slices don’t stick.
If you want the best results when you bake sliced zucchini, a rimmed sheet pan works better than a flat cookie sheet because it keeps the slices from sliding around.
2. Slice the Zucchini Evenly
Wash your zucchini and pat it dry, then trim off both ends.
Cut the zucchini into rounds about ¼ inch thick, or slice them lengthwise into planks if you prefer.
The key when you bake sliced zucchini is keeping the slices uniform so they cook at the same rate.
3. Salt and Drain the Slices
Zucchini is mostly water, which is why so many people end up with soggy results when they bake sliced zucchini.
Sprinkle the slices with a little salt and let them sit for 10 to 15 minutes.
Then blot them dry with paper towels or a clean kitchen towel.
This one step makes a huge difference in how your baked sliced zucchini turns out.
4. Toss With Oil and Seasonings
In a bowl, toss the dry slices with a couple of tablespoons of olive oil.
Add salt, black pepper, garlic powder, and a pinch of Italian seasoning or paprika.
You can also add grated parmesan or nutritional yeast if you want a cheesy, savory kick when you bake sliced zucchini.
5. Spread Them Out and Bake
Arrange the slices in a single layer on your prepared pan.
Don’t crowd them, because steamed zucchini won’t brown.
Bake for 18 to 25 minutes, flipping halfway through, until the edges are golden and the centers are tender.
If you like them extra crispy, bake sliced zucchini for a few minutes longer and broil for the last 2 minutes.
Tips for Crispy Baked Sliced Zucchini
A few small tweaks separate good baked sliced zucchini from unforgettable baked sliced zucchini.
Keep these pointers in mind.
1. Coat Slices for Extra Crunch
If you want a crunchy crust, dip the slices in beaten egg, then press them into panko breadcrumbs or almond flour mixed with parmesan.
This turns your baked sliced zucchini into something closer to zucchini chips.
2. Use the Right Rack Position
Place the pan on the middle rack, or move it to the top third for more browning.
When you bake sliced zucchini at a higher temperature, the moisture evaporates faster, giving you crispier edges.
3. Don’t Skip the Flip
Flipping the slices halfway through helps both sides brown evenly.
It also keeps the bottoms from getting stuck or turning mushy when you bake sliced zucchini.
4. Add Cheese at the End
Sprinkle mozzarella or parmesan over the slices during the last 5 minutes of baking.
This way the cheese melts without burning, and your baked sliced zucchini gets a gooey, golden finish.
Best Ways to Serve Baked Sliced Zucchini
Once you know how to bake sliced zucchini, you’ll find endless ways to use it.

The slices hold their shape well, so they don’t turn to mush.
3. On Sandwiches and Wraps

It adds a nice savory note without overpowering the other ingredients.
