Cheesy Zucchini Stacks are a simple low-carb side dish made with tender zucchini, melted mozzarella, Parmesan, garlic, and Italian herbs. The zucchini is layered with cheese and baked until golden, bubbly, and delicious.
Ingredients
For the Zucchini Stacks
3 medium zucchini
1 cup shredded mozzarella cheese
½ cup freshly grated Parmesan cheese
2 cloves garlic, minced
1 tablespoon olive oil
½ teaspoon Italian seasoning
¼ teaspoon garlic powder
¼ teaspoon paprika
½ teaspoon salt
¼ teaspoon black pepper
2 tablespoons fresh parsley, chopped
Optional Ingredients
¼ teaspoon red pepper flakes
2 tablespoons chopped fresh basil
¼ cup ricotta cheese
¼ cup shredded cheddar cheese
2 tablespoons chopped sun-dried tomatoes
Nut Information
This recipe is naturally nut-free when prepared with the ingredients listed above.
Zucchini, mozzarella, Parmesan, garlic, herbs, and olive oil do not naturally contain peanuts or tree nuts.
Parmesan and mozzarella are dairy products, not nuts.
The optional ingredients listed above do not require nuts.
If using packaged shredded cheese, seasonings, or other processed ingredients, check the label for possible nut cross-contact if preparing this for someone with a severe allergy.
Avoid adding almond flour, walnuts, pecans, pine nuts, or other nuts if you need the recipe to remain nut-free.
If using pesto as an optional topping, check the ingredients because traditional pesto commonly contains pine nuts.
Instructions
1. Prepare the Oven
Preheat your oven to 400°F (200°C).
Line a baking sheet with parchment paper and lightly brush it with olive oil.
2. Prepare the Zucchini
Wash and dry the zucchini.
Cut each zucchini into thin, even slices approximately ¼ inch thick.
Try to keep the slices similar in size so they cook evenly.
Place the zucchini slices on paper towels.
Lightly sprinkle them with salt and let them sit for approximately 10 minutes.
Pat them thoroughly dry with paper towels.
This removes excess moisture and helps prevent watery stacks.
3. Prepare the Seasoning
In a small bowl, combine:
Olive oil
Minced garlic
Italian seasoning
Garlic powder
Paprika
Black pepper
Mix well.
4. Season the Zucchini
Brush each zucchini slice lightly with the garlic-herb oil mixture.
Don’t use too much oil because zucchini naturally releases moisture during baking.
5. Build the Stacks
Arrange one zucchini slice on the prepared baking sheet.
Sprinkle with a small amount of mozzarella and Parmesan.
Place another zucchini slice on top.
Repeat the zucchini and cheese layers until you have stacks approximately 3–4 slices high.
Finish each stack with mozzarella and Parmesan on top.
Don’t make the stacks too tall because they may become unstable while baking.
6. Bake
Place the baking sheet in the preheated oven.
Bake for approximately 15–20 minutes, or until:
The zucchini is tender.
The cheese is melted.
The tops are golden brown.
For extra browning, switch the oven to broil for 1–2 minutes at the end.
Watch carefully because the cheese can burn quickly.
7. Garnish
Remove the zucchini stacks from the oven.
Allow them to rest for 3–5 minutes.
Sprinkle with fresh parsley or basil.
Add red pepper flakes if you like a little heat.
Serve warm.
Air Fryer Method
Preheat the air fryer to 375°F (190°C).
Assemble the zucchini stacks in the air fryer basket.
Cook for approximately 8–12 minutes.
Check around 8 minutes.
Continue cooking until the zucchini is tender and the cheese is golden and melted.
Let them rest for a few minutes before serving.
Depending on the size of your air fryer, you may need to cook them in batches.
Tips for the Best Zucchini Stacks
Choose medium-sized zucchini rather than very large zucchini because they contain less excess water.
Slice the zucchini evenly.
Don’t skip the salting and drying step.
Use freshly grated Parmesan for better melting and flavor.
Don’t overload each layer with cheese.
Keep the stacks relatively short so they remain stable.
Broil briefly at the end for a beautifully browned cheese topping.
Let the stacks rest before serving so the cheese can set slightly.

Storage
Allow leftovers to cool completely.
Store in an airtight container in the refrigerator for 3–4 days.
For best results, reheat in an oven or air fryer rather than the microwave.
Reheating
Oven:
Heat at 375°F (190°C) for approximately 8–10 minutes.
Air fryer:
Heat at 350°F (175°C) for approximately 3–5 minutes.
The microwave will work, but the zucchini will be softer and less crispy.
Freezing
Freezing is not recommended because zucchini contains a lot of water and can become soft and watery after thawing.
For the best texture, prepare and enjoy the stacks fresh.

Q: Are they keto-friendly?
Yes. The basic recipe is low in carbohydrates and can fit into a keto-style meal.
Q: How do I stop the zucchini from becoming watery?

Q: Can I use yellow squash instead of zucchini?
Yes. Yellow squash can be substituted in equal amounts.
Q: Can I use cheddar instead of mozzarella?
Yes. Cheddar gives the stacks a stronger flavor and works well with Parmesan.
Q: Can I use ricotta?
Yes. Spread a very thin layer of ricotta between the zucchini slices before adding mozzarella.
Q: Can I make these dairy-free?
Yes, but you will need suitable dairy-free mozzarella and Parmesan alternatives.
Q: Are these zucchini stacks nut-free?
Yes. The basic recipe contains no peanuts or tree nuts. Always check packaged ingredients for allergy warnings if necessary.
Q: Can I add breadcrumbs?
Yes, but breadcrumbs will increase the carbohydrate content. For a low-carb option, use a suitable low-carb breadcrumb alternative.
Q: Can I prepare them ahead of time?
You can slice and season the zucchini several hours ahead, but it is best to assemble and bake the stacks shortly before serving.
Q: Can I add meat?
Yes. Finely chopped cooked chicken, turkey, beef, or pepperoni can be layered between the zucchini slices.
Q: Why are my stacks falling apart?
They may be too tall or contain too much moisture. Keep them 3–4 zucchini slices high, dry the zucchini well, and allow them to rest for a few minutes after baking.
Q: Can I use frozen zucchini?
Fresh zucchini is strongly recommended. Frozen zucchini releases too much moisture and will not produce the same texture.
