3 Ingredient Parmesan Zucchini Stacks (Keto, Low Carb)

These parmesan zucchini stacks are a delicious side dish and a great low carb alternative to potato stacks. The stacks have a crunchy top layer and a cheesy, creamy center. They are just 3 ingredients and easy to make.

This is such a fun appetizer or side dish. I got the idea from the crispy potato stacks I’ve previously made. However, these are much easier and they are low carb.


  • Zucchini
  • Parmesan Cheese
  • Pork Rind Breadcrumbs or Panko Breadcrumbs

To keep these keto-friendly, I used pork rind crumbs to add the crunchy top. If you are not on a keto diet, you can also use panko breadcrumbs and it works just as well. I don’t recommend regular breadcrumbs because they don’t crisp up as much.

How to Make Zucchini Stacks

  • The zucchini is first thinly sliced to 1/8 inch thick. If you have a mandoline slicer, I highly recommend using that as it will make cutting go a lot faster and help ensure that your zucchini is evenly sliced.
  • The zucchini slices are sprinkled with a light layer of parmesan cheese.
  • The zucchini slices are then stacked up, about 5 to 6 per stack.
  • Finally, the zucchini stacks are topped with breadcrumbs.
  • The zucchini stacks are then put into muffin cups and baked for about 10 minutes or until the cheese is melted, zucchini is soft and breadcrumbs are crispy.

  • 1 large (289 g, 10.2 oz) zucchini thinly sliced to 1/8 inch thick slices
  • 1/2 cup (54 g) finely shredded parmesan cheese fresh (not the shelf stable kind)
  • 5 tsp (10 g) pork rind breadcrumbs or panko breadcrumbs


  • Preheat oven to 400°F. Lightly grease the interior of a standard 12 cup muffin pan. Depending on the length of your zucchini, you may not need all 12 cavities. I only used 10.
  • Lay out all of your zucchini slices in a single layer with no overlaps. Lightly cover the surface of each slice with cheese. I used slightly more than 1/2 tsp of cheese for each slice, but your amount may vary depending on how wide your zucchini slices are.
  • Stack the zucchini slices on top of each other, about 5 to 6 slices high per stack. You don't want to stack too many because then your stack will be unstable. Sprinkle about 1/2 tsp of pork rind crumbs or panko breadcrumbs on the top layer of zucchini for each stack.
  • Carefully transfer the zucchini stacks to the prepared muffin cups.
  • Bake zucchini stacks for about 10-12 minutes or until tops are crispy, cheese is melted and zucchini is cooked. If desired, set your oven to low broil and broil a few minutes until your cheese begins to blister. This step is completely optional but I like that it added some color on the cheese.
  • If any of the zucchini stacks have slid sideways, you can quickly straighten them while the cheese is still melty. Carefully remove the zucchini stacks (I used a fork to lift the stack from the bottom) and serve while warm.


  • I recommend using a mandoline slicer to slice your zucchini. It will be much faster and your slices will be more even. I used the widest setting to get the 1/8 inch.
  • I don't recommend slicing your zucchini thinner than 1/8 inch because the zucchini shrinks when cooking and your slices will fall apart if they are too thin.
  • I have only tested this recipe with fresh Parmesan cheese. I think if you try to use the grated shelf-stable kind, the cheese won't melt enough to stick the slices together.
  • You need to bake these stacks in muffin molds, otherwise the slices will slide out during baking.
  • I use this oxo mandoline slicer.*
  • I used Pork King Good unseasoned pork rind crumbs*.

  1. I just made these.  Excellent 
    I used hot and crispy panko bread crumbs 

    I wonder if the zucchini slices would be more crisp if I allowed some of the water to drain out from each slice 

    I used a silicone muffin pan so not necessary to grease the pan 

    These were delicious.  Thanks for the recipe 

  2. Could you use summer yellow squash?

  3. my daughter and i made these last night for the first time, and while i miss potatoes terribly on keto, these are fabulous. we doubled the recipe and there were no leftovers…not so much as a crumb.
    we have already purchased more zucchini for tomorrow’s dinner…sooo delish!

  4. Hi Jennifer/Kirbie- made this recipe for zucchini stacks tonight and they disappeared like magic!  What a tasty and fun way to prepare, perfect for kids to construct AFTER AN ADULT SLICES WITH A MANDOLINE of course. We used fresh shredded Parmesan and added a small sprinkle of seasoning like Badia’s 14 seasoning blend (or Trader Joe’s 21) as we built our stacks since we used plain Panko, & sprayed the panko top with a little cooking spray to increase golden crunch.  Thanks!

  5. These sound so good. I am anxious to try them.

  6. I made the zucchini crisps and they came out great. I used parmesan shavings on top of each zucchini and placed in air fry basket. It worked great.

  7. I’m not a dietitian, either, but you should know that there is no way that one serving is 27kcal. That’s 27 thousand calories. Drop the k.
