Air Fryer Zucchini Lasagna is a lighter twist on classic lasagna made with thin zucchini ribbons, creamy ricotta, rich tomato sauce, and plenty of melted mozzarella. It’s cheesy, comforting, and easy to prepare in the air fryer without using traditional pasta sheets. Serve it with a fresh arugula salad for an easy vegetarian lunch or dinner.

If you love lasagna but not the heavy feeling afterwards, this zucchini version is the answer. The biggest challenge with any vegetable lasagna is excess water, so this recipe walks you through slicing, layering and resting the zucchini so every slice holds together on the plate.

Julia’s Tip: Salt the zucchini slices and let them rest on a kitchen towel for about 15 minutes, then pat them dry before layering. It is the one step that keeps the lasagna from turning watery, so please don’t skip it.

Why You’ll Love This Air Fryer Zucchini Lasagna

This recipe gives you the creamy, cheesy comfort of lasagna with a lighter vegetable-based twist.

The zucchini becomes tender while the ricotta stays creamy and the mozzarella develops a golden, bubbly topping. It’s perfect when you want a satisfying vegetarian meal without making a large oven-baked lasagna.

Tips for the Best Zucchini Lasagna

Pat the zucchini slices very dry before assembling. If the zucchini contains too much water, the finished lasagna can become watery.

A mandoline creates even ribbons quickly, but a sharp knife or vegetable peeler also works.

Choose a thicker marinara sauce rather than a very watery tomato sauce for the best consistency.

How to Make Air Fryer Zucchini Lasagna Less Watery

The key to a firm zucchini lasagna is removing as much moisture as possible before assembling.

After slicing the zucchini, place the ribbons on paper towels and lightly salt them. Let them sit for about 10 minutes, then pat them very dry.

This helps prevent excess liquid from collecting in the baking dish and keeps the ricotta layers creamy instead of watery.

Best Cheese for Zucchini Lasagna

Ricotta gives the filling its creamy texture, while mozzarella creates the golden, melted top. For extra flavor, you can also add grated Parmesan between the layers.

Full-fat cheeses generally give the richest result, but part-skim ricotta and mozzarella can also be used if you prefer a lighter version.

Storage & Reheating

Store leftover zucchini lasagna in an airtight container in the refrigerator for up to 3 days.

Reheat individual portions in an air fryer-safe dish at 350°F (175°C) for about 5–7 minutes, or until heated through.

If liquid collects in the container while refrigerated, simply drain a little before reheating.

Frequently Asked Questions

Can I make zucchini lasagna ahead of time?

Yes. Assemble it several hours in advance, cover it, and refrigerate until ready to cook.

Why is my zucchini lasagna watery?

Zucchini naturally contains a lot of water. Patting the ribbons dry before layering helps reduce excess moisture.

Can I add meat?

Yes. Cooked ground beef, turkey, or chicken can be added between the layers.

Can I use cottage cheese instead of ricotta?

Yes. Cottage cheese works well, although the texture will be slightly different.

Is zucchini lasagna low carb?

Yes. Replacing pasta sheets with zucchini makes this lasagna much lower in carbohydrates than a classic version. Choose a marinara without added sugar to keep the carbs as low as possible.

Can I use yellow squash instead of zucchini?

Yes, yellow squash works the same way. You can also mix both for a colorful lasagna. Slice them to the same thickness so they cook evenly.

Do I need to peel the zucchini?

No. The skin holds the slices together and adds color. Just wash the zucchini well and trim the ends.

What to Serve with Zucchini Lasagna

A fresh arugula salad with shaved Parmesan and balsamic glaze works perfectly alongside this lasagna.

You can also serve it with roasted vegetables, garlic bread, a tomato salad, or a simple cucumber salad.

Easy Variations

Add sautéed spinach or mushrooms to the ricotta mixture for extra vegetables.

For more Mediterranean flavor, add sun-dried tomatoes, olives, or fresh oregano.

You can also sprinkle Parmesan between the layers for an even richer cheese flavor.

Ingredient Notes and Substitutions

Every ingredient in this zucchini lasagna has a job, so it helps to know where you can swap and where you should not.

• Zucchini: Choose medium, firm zucchini. Very large ones contain more water and seeds, which makes the layers soft. Slice them about 1/8 inch (3 mm) thick with a mandoline or vegetable peeler.
• Ricotta: Whole-milk ricotta gives the creamiest result. Part-skim works too, but drain it in a sieve for 10 minutes first.
• Egg: The egg binds the ricotta so the filling sets instead of running. For an egg-free version, mix the ricotta with 2 tablespoons of grated Parmesan instead.
• Tomato sauce: Use a thick marinara. A thin sauce adds extra liquid that the zucchini cannot absorb.
• Mozzarella: Low-moisture shredded mozzarella browns better than fresh mozzarella balls.

How to Layer Zucchini Lasagna in the Air Fryer

Use an oven-safe dish that fits your air fryer basket with a little space around the edges so the hot air can circulate. A 6- or 7-inch round or square dish works well for most basket air fryers.

• Spread a thin layer of sauce on the bottom so the zucchini does not stick.
• Add a layer of overlapping zucchini slices, then spoon over some ricotta mixture.
• Repeat with sauce, zucchini and ricotta until the dish is full, finishing with sauce.
• Top with mozzarella and cover loosely with foil for the first part of cooking, then uncover so the cheese turns golden.

Let the lasagna rest for 5 to 10 minutes before slicing. This short rest helps the layers set and gives you clean, neat pieces.

Can You Freeze Zucchini Lasagna?

Yes, but the texture is best when you freeze it before baking. Assemble the lasagna in a freezer-safe dish, wrap it tightly and freeze for up to 2 months. Thaw it overnight in the fridge, pour off any liquid that collects and air fry as directed, adding a few extra minutes. Baked leftovers can also be frozen in portions, although the zucchini will be a little softer after reheating.
