💛 Why you’ll love it

Why are zucchinis so ubiquitous these days?

It’s not like you’d sink your teeth into one raw. But when you spiralize them and heat them in a frying pan with some olive oil, they transform from a dull squash into a delectable healthy noodle alternative.

And, as you’ll see, when you slice them up into silver dollar size pieces and bake them in the oven for a couple of hours, they become tasty potato chip healthy alternatives.

It’s actually really easy to turn zucchini slices into zucchini chips.

💭 Tips

  • Remove moisture from the zucchini. The more water you pull out of your veggies, the better your chips will turn out.
  • Use a mandolin slicer. This ensures that all your slices bake at the same rate for a nice and crispy zucchini chip.
  • Bake at a low temperature. This is key to turning this summer squash into a chip alternative.

🔪 Instructions

This baked zucchini chips recipe is incredibly simple. You’ll have crispy chips in no time at all. Here’s a bit more information about how to make them.

Slice the zucchini

To begin, slice two medium-size fresh zucchini into thin, round pieces. For best results, use a mandoline slicer.

Remove moisture

After the slicing is done, remove any excess moisture from the veggie by placing the zucchini slices between sheets of paper towels.

I like to put the sliced zucchini in the fridge for at least a couple of hours. You can place them on the humidity-controlled shelf.

Just remember, for tasty chips, the drier, the better.

Add olive oil and salt

Now that your zuke slices are bone dry, place them in a large mixing bowl. Add one tablespoon of olive oil and half a teaspoon of sea salt to the bowl.

Now, gently toss so that the slices are coated with oil and salt.

Place zucchini on a baking sheet

From here, lay the veggie slices on a parchment paper-lined baking sheet in a single layer. You can also use a silicone baking mat. Either way, place the zucchini on top of the prepared baking sheet.

Bake the zucchini chips

Set the oven to bake at 225°F and cook them for 2 hours or until the chips are golden brown. If not yet crispy, keep checking every 15 minutes or so until the desired crunch factor is reached.

🍽️ Serving suggestions

These zucchini chips are a wonderful choice if you love healthy food. And they are a wonderful way to use fresh summer produce.

After you make them, serve them with your favorite dipping sauce. I like to make a low-carb ranch or even keto tzatziki sauce. I also think some avocado mayo would taste delicious as a simple dipping sauce!

There are other healthy recipes that taste like potato chips that would be delicious with these zucchini chips. Salt and vinegar cucumber chips only have 1 gram of net carbs in each serving.

You can also serve these chips with a healthy snack like keto hummus.

📒 Variations

There are a bunch of different ways that you can make these healthy baked zucchini chips.

First, coat the chips with grated parmesan cheese. It’s a low-carb substitute for panko bread crumbs.

You can also season the chips! I like to add garlic powder or Everything but the Bagel Seasoning. Or, sprinkle the crispy zucchini chips with some onion powder and chili powder.

🙋 FAQs

Before we get to the printable recipe card, here are some questions people often ask about this crispy sliced zucchini recipe.

How do you keep zucchini chips from getting soggy?

Zucchini chips can be kept from getting soggy by making sure they are completely dry before you put them in the bag or container. You can also put them in a sealed bag with a paper towel to absorb any excess moisture.

Can you cook zucchini chips on aluminum foil?

Yes, you can cook zucchini chips on aluminum foil. Place the oiled and salted zucchini slices on a piece of aluminum foil, and then fold the aluminum foil over the zucchini slices. Cook them in the oven for 10-15 minutes, or until they are crispy.

How do you make each zucchini slice the same width?

One way to ensure your zucchini slices are all the same width is to use a mandoline slicer. This kitchen tool has a series of adjustable blades that will evenly slice your vegetables into thin, even pieces. If you don’t have a mandoline slicer, you can also use a sharp knife to slice your zucchini into thin strips. Just be careful not to cut yourself!

How do you store baked zucchini chips?

Keep the crispy zucchini rounds in an airtight container and store them at room temperature for up to a week.

  • Slice zucchini into thin rounds with a mandolin slicer.

  • Place zucchini slices between paper towels to remove excess moisture. Allow to sit in the refrigerator for at least 2 hours. The drier the better.

  • Combine the zucchini slices, oil, and salt in a large bowl. Toss to coat.

  • Lay zucchini slices on a parchment paper or silicone baking mat lined rack on top of a baking pan. (I find raising the slices off the bottom of the pan helps to crisp them up faster with the air underneath)

  • Bake at 225°F for 2-3 hours or until zucchini slices have reached desired crispness.


Be sure to remove as much moisture from the zucchini as possible before baking. Salting the zucchini slices usually helps them to release the liquid faster.
