Ingredients
- 2 large zucchini
- Olive-oil spray
- Black pepper, to taste
- Salt, to taste
- ¼ tsp paprika
- ½ tsp garlic powder
- 1 tsp Italian seasoning
- 2 tbsp grated Parmesan
- ½ cup part-skim shredded mozzarella, divided
- Fresh parsley, optional, for garnish
Instructions
- Preheat the oven to 425°F (220°C). Line a baking sheet with parchment paper.
- Slice the zucchini into ½-inch-thick rounds. Pat both sides very dry with paper towels.
- Arrange the zucchini rounds in a single layer. Lightly coat with olive-oil spray and season with garlic powder, Italian seasoning, paprika, salt, and black pepper.
- Bake for 8–10 minutes to soften the zucchini and drive off some excess moisture.
- Remove from the oven. Create 4 stacks, using 2–3 zucchini rounds for each.
- Add a small amount of mozzarella between each zucchini layer. Keep the cheese modest so it melts into the stack without overwhelming the zucchini.
- Divide the remaining mozzarella and Parmesan over the tops of the four stacks.
- Return to the oven and bake for 8–10 minutes, until the cheese is melted, bubbling, and beginning to brown.
- Switch the oven to broil and broil for 1–2 minutes, watching closely, until the cheese develops deeply golden toasted spots.
- Let the stacks rest for 2–3 minutes, then garnish with fresh parsley if desired and serve warm.
Recipe Notes: Drying the zucchini before baking is important because zucchini naturally contains a lot of water. For the best texture, use large, firm zucchini and don’t overcrowd the baking sheet.
Why These Cheesy Zucchini Stacks Work
These cheesy zucchini stacks take a simple vegetable and turn it into something that feels much more indulgent. The zucchini becomes tender in the oven while the mozzarella melts between the layers, and Parmesan creates a savory, golden crust on top.
The key is the two-stage baking method. The first bake softens the zucchini and helps remove excess moisture. The second bake focuses on melting the cheese, while a quick broil creates those browned, toasted patches that make the finished stacks especially appealing.
If you’ve ever baked zucchini only to end up with a watery dish, don’t skip the pre-bake. It makes a noticeable difference.
How to Make Cheesy Zucchini Stacks
1. Prepare the zucchini
Start by choosing two large zucchini that feel firm and have smooth, unblemished skin. Wash and dry them thoroughly, then cut them into rounds about ½ inch thick.
Try to keep the slices as uniform as possible. Even slices cook at roughly the same rate, while very thin pieces can become soft before the cheese is ready.
Pat the rounds thoroughly with paper towels. This may seem like a small step, but it helps remove surface moisture before the zucchini goes into the oven.
Tip: Don’t slice the zucchini too thin. Thicker rounds hold their shape better and give the stacks enough structure.
2. Season and pre-bake
Place the zucchini rounds on a parchment-lined baking sheet in one layer. Give them a light mist of olive-oil spray, then season with garlic powder, Italian seasoning, paprika, salt, and pepper.
Bake at 425°F for 8–10 minutes.
The zucchini should be softened but not falling apart. You’re not trying to fully cook it during this stage. The goal is to start tenderizing the rounds while allowing some of their water to evaporate.
Tip: Leave space between the rounds rather than piling them together. Crowding traps steam and can make the zucchini softer and wetter.
3. Build the stacks
Take the partially baked zucchini out of the oven. Arrange the rounds into four portions, using two or three pieces per stack.
Place a little shredded mozzarella between each round. The amount doesn’t need to be exact. A thin layer is enough to help the pieces stick together as the cheese melts.
This is one place where restraint pays off. Adding a large amount of cheese between every layer can cause it to spill onto the baking sheet before the zucchini is finished.
4. Add the cheesy topping
Divide the remaining mozzarella between the four stacks, placing it over the top. Sprinkle Parmesan over each one.
The mozzarella gives you the stretchy, creamy melt, while Parmesan adds a more concentrated salty and nutty flavor and helps the tops brown.
Return the baking sheet to the oven for 8–10 minutes.
5. Broil until golden
Once the cheese is fully melted and bubbling, turn on the broiler. Broil the stacks for 1–2 minutes, keeping a close eye on them.
The goal is a deeply golden top with a few toasted spots. Cheese can go from beautifully browned to burnt very quickly under a broiler, so don’t walk away during this step.
Let the finished stacks rest for a couple of minutes before serving. This gives the melted cheese a chance to settle and makes the stacks easier to transfer.
Ingredient Details and Smart Substitutions
Zucchini
Large zucchini work particularly well because their rounds are substantial enough to stack. Choose firm zucchini rather than very soft or shriveled ones.
Yellow summer squash can also be used in place of some or all of the zucchini. The texture and moisture content are similar, although the finished stacks will have a slightly different appearance.
Part-Skim Mozzarella
Part-skim mozzarella keeps the recipe lighter while still providing the gooey melt you want. Shredding it yourself can give you excellent melting, although pre-shredded mozzarella is perfectly convenient.
For a stronger flavor, use part-skim Italian-blend cheese, keeping the quantity similar.
Parmesan
Parmesan brings savory depth and helps the top develop a browned finish. Freshly grated Parmesan generally melts more smoothly, but packaged grated Parmesan can work as well.
Italian Seasoning
Italian seasoning gives the zucchini an easy blend of herbs without requiring several individual spices. If you don’t have it, use a mixture of dried oregano and basil.
Garlic Powder and Paprika
Garlic powder distributes evenly across the zucchini without adding extra moisture. Paprika contributes a subtle earthy flavor and attractive color.
For more heat, replace the paprika with a small pinch of red pepper flakes.
Equipment Alternatives
You don’t need special equipment for this recipe.
- No parchment paper? Lightly coat the baking sheet with cooking spray or use a silicone baking mat.
- No pastry brush? Olive-oil spray makes it easy to apply a very thin coating.
- No broiler? Simply leave the stacks in the hot oven a little longer until the cheese is golden, watching carefully.
- No large baking sheet? Use two smaller sheets rather than overcrowding the zucchini.
Variations and Serving Suggestions
Add a Little Heat
For spicy cheesy zucchini stacks, add ¼ tsp crushed red pepper flakes to the seasoning mixture. You can also add a pinch of cayenne if you enjoy more heat.
Add Fresh Herbs
After baking, scatter chopped parsley or basil over the top. Fresh herbs add a bright contrast to the rich melted cheese.
Make Them Extra Savory
Add ½ tsp onion powder to the seasoning mixture for a deeper savory flavor without significantly changing the preparation.
Try Different Cheese
Replace part of the mozzarella with a small amount of shredded provolone for a more pronounced Italian-style flavor. Keep the overall amount of cheese close to the recipe quantity if you’re trying to maintain the intended nutritional profile.
Make It a Complete Meal
Serve the stacks alongside grilled chicken, turkey meatballs, roasted fish, or a simple green salad. They also work beautifully as a vegetable side with pasta or a bowl of soup.
For an appetizer, make smaller stacks with two zucchini rounds each and serve them warm as individual bites.
Storage, Reheating, and Make-Ahead Tips
These stacks are best immediately after baking because that’s when the cheese is at its most bubbly and the zucchini has the best texture.
For leftovers, let the stacks cool and transfer them to an airtight container. Refrigerate for up to 3 days.
To reheat, place them on a baking sheet and warm at 375°F (190°C) for approximately 8–10 minutes, or until heated through. Finish with a brief broil if you want to restore some of the golden cheese topping.
The microwave works in a pinch, but it can make the zucchini softer and the cheese less appealing.
Can You Make Them Ahead?
You can slice and season the zucchini several hours ahead, then refrigerate it in a covered container. For the best result, pat it dry again before baking.
The stacks themselves are best assembled shortly before the final bake. This prevents the cheese from sitting against the moist zucchini for too long.
Freezing
Freezing isn’t recommended for the finished stacks. Zucchini releases additional water after thawing, which can make the texture noticeably softer and wetter.

Frequently Asked Questions
Can I use small zucchini instead of large zucchini?
Yes. You’ll need enough rounds to make four stacks, and smaller zucchini will produce smaller individual portions. Keep the slices around ½ inch thick so they don’t become too delicate.
Why are my zucchini stacks watery?
Zucchini naturally contains a significant amount of water. Not drying the rounds, skipping the pre-bake, overcrowding the pan, or using very thin slices can all contribute to excess moisture.
Pat the zucchini dry and give the rounds enough space on the baking sheet.
Can I use fresh garlic instead of garlic powder?
You can, but garlic powder is more convenient here because it distributes evenly over the zucchini. If using fresh garlic, finely mince a small clove and mix it with the olive-oil spray before lightly coating the rounds.
Can I make these without Parmesan?
Yes. Simply replace the Parmesan with a little additional mozzarella. Keep in mind that Parmesan contributes extra savory flavor and helps create a browned topping.
Can I use yellow squash?
Absolutely. Yellow squash is a practical substitute for zucchini and can be used in equal amounts.
How do I keep the stacks from falling apart?
Use zucchini rounds that are thick and evenly sliced, and don’t overload the middle with cheese. Allow the baked stacks to rest for 2–3 minutes before moving them.
Can I prepare these in an air fryer?
Yes, although you’ll need to work in batches depending on the size of your basket. Air fry the seasoned zucchini until partially tender, assemble the stacks, then continue cooking until the cheese melts and browns. Keep a close eye on them because air fryers vary considerably.
What should I serve with them?
These cheesy zucchini stacks pair especially well with grilled chicken, turkey, fish, meatballs, roasted vegetables, soup, or a crisp green salad. They’re versatile enough to work as either a side dish or a light vegetarian option.
Final Tips for the Best Results
The most important trick is to remove as much surface moisture from the zucchini as possible before baking. The second is to keep the cheese layers modest and save a generous portion for the top.
Don’t skip the final broil, either. Those deeply browned cheese spots provide a big flavor payoff with almost no extra effort.
Serve the stacks warm, while the mozzarella is still soft and stretchy. A little fresh parsley on top adds color and freshness, but the golden cheese should remain the star.
