Simple Quick Parmesan Zucchini Bites

That season comes every year where all my neighbors and everyone I know has zucchini coming out of their eyeballs from their gardens. Along with loads of zucchini bread and grilled zucchini I love making these parmesan zucchini bites as a quick side. 

I love the simplicity of this recipe. Parmesan cheese is one of my favorites since it has a beautiful salty nutty flavor. It needs a high temperature to melt well which is why I broil these right at the end to crisp up the cheese. Your family is sure to enjoy these soft and salty cheesy nibbles.

How To Make Parmesan Zucchini

To make this recipe, you’ll need:


  • Zucchini – zucchini have a soft texture and a mild sweet flavor when baked. They release a lot of moisture when heated so make sure you pat your zucchini slices down well after cutting it and before seasoning and baking. 
  • Olive oil – olive oil has a slightly bitter flavor and is perfect for coating the zucchini so it doesn’t stick to the pan. Feel free to use your favorite oil. 
  • Garlic salt – garlic salt will add a strong garlic flavor without the liquid that would come from fresh garlic. You can sprinkle a little more on at the end if you want a stronger garlic taste. 
  • Salt and pepper – use fresh ground salt and pepper to draw the natural flavor and moisture out of the zucchini. 
  • Parmesan – you want to use fresh grated or pre-shredded parmesan for this recipe since it will melt well. Parmesan has a rich, nutty, salty taste and is the star of the show. 

Once you’ve gathered your ingredients, we will use the following method:

  • Step 1 – Put the zucchini slices on a baking sheet and drizzle with olive oil. Spread the oil out until they are well covered then spread them out into a single layer. Sprinkle with the spices and top each slice with parmesan.
  • Step 2 – Bake at 450 degrees for about 10 minutes or until the zucchini are fork tender then broil them on high for 2-3 minutes or until the cheese is bubbly and browned. 
  • Step 3 – Enjoy! 

Tips and Tricks To Perfect Parmesan Zucchini:

Check out these tips and tricks for perfect parmesan zucchini bites! 

Tip 1 – Use zucchini and yellow squash. You can use a mixture of sliced zucchini and yellow squash for this recipe if you want. You can bake the yellow squash the same way you bake the zucchini. 

Tip 2 – Add more spices. You can add additional spices to your spice mix. I like to add some red pepper flakes and some Italian seasonings if I am serving these alongside pasta. I use  about ½ teaspoon sprinkled across the zucchini to get that extra flavor across. 


Can I substitute a different cheese? – Yes, just remember that different cheeses will melt at different rates. A medium soft cheese like cheddar will melt faster than parmesan. Feel free to use a mixture of cheeses too. 

What’s the best way to keep leftovers? You can keep leftovers in an airtight container for 4-5 days in the refrigerator. Reheat them in the microwave

What to serve with Parmesan Zucchini?

I love to making these alongside, Creamy Lemon Garlic Pasta, a delicious and simple 20 Minute Garlic Butter Chicken and Mushroom Pasta, some Roasted Tomato and Goat Cheese Pasta, or our Lemon Garlic Butter Chicken Thighs Recipe! These zucchini slices are also a great easy appetizer for big holiday dinners for low-carb diners, making it perfect alongside Ribeye Roast!

    This was fabulous! I did skip the regular salt since I already used the garlic salt, but otherwise, I followed it to the letter. Delicious! Now I’m experimenting with Colby Jack and chili powder in place of the parmesan and the pepper, but I absolutely love the original version. 5 stars for me!
