Grilled Zucchini Lasagna with Herbed Ricotta, Feta & Lemon

There are some recipes that just feel like summer on a plate.

This Grilled Zucchini Lasagna with Herbed Ricotta, Feta & Lemon is one of them.

Instead of traditional pasta sheets, this version uses tender grilled zucchini layered with creamy herbed ricotta, salty feta, fresh herbs, and a bright little squeeze of lemon.

It’s comforting without feeling heavy, fresh without being boring, and honestly one of the most delicious ways I’ve found to use up a pile of zucchini.

I first made this on a warm weekend when I had more zucchini than I knew what to do with.

I had originally planned to make a simple grilled vegetable side dish, but then I started thinking about lasagna.

I wanted those beautiful layers, the creamy filling, and the comforting feeling of a baked casserole—but I didn’t really want a heavy pasta dish.

So I grilled the zucchini instead.

Then I mixed ricotta with fresh herbs, feta, lemon zest, and a little black pepper.

Once everything was layered together, I baked it until warm and lightly golden.

The smell coming from the oven was incredible.

When I finally cut into it, the layers held together beautifully.

The ricotta was creamy, the feta added little salty bites, and the lemon kept everything tasting bright and fresh.

My family loved it.

Even the people who usually ask, “Where’s the pasta?” went back for seconds.

Now it’s one of those recipes I make whenever zucchini is plentiful, especially on weekends when I want something that feels special without being overly complicated.

How to Make Grilled Zucchini Lasagna

1. Prepare the Zucchini

Wash and dry the zucchini.

Trim off both ends.

Slice the zucchini lengthwise into thin strips, approximately ⅛–¼ inch thick.

A mandoline can make this easier, but a sharp knife works perfectly well.

Try to keep the slices as uniform as possible.

2. Season the Zucchini

Place the zucchini slices on a large tray.

Brush lightly with olive oil.

Season both sides with salt, black pepper, and garlic powder.

Don’t use too much salt at this stage because feta will add plenty of salt later.

3. Grill the Zucchini

Heat a grill or grill pan over medium-high heat.

Grill the zucchini slices for approximately 2–3 minutes per side, or until they develop beautiful grill marks and become tender.

You don’t want them completely soft.

They should still have enough structure to form the layers.

Transfer the grilled zucchini to a plate.

4. Let the Zucchini Release Excess Moisture

This step is important.

Zucchini contains a lot of water, and too much moisture can make your lasagna watery.

Arrange the grilled slices on paper towels or a clean kitchen towel.

Let them sit for several minutes.

Pat away any visible excess moisture.

5. Make the Herbed Ricotta

Add the ricotta to a large bowl.

Stir in:

• Feta
• Parsley
• Basil
• Dill
• Lemon zest
• Lemon juice
• Garlic
• Black pepper
• Salt

Mix until creamy and well combined.

Taste before adding more salt.

The feta is already naturally salty.

6. Assemble the Lasagna

Lightly grease a baking dish.

Arrange a layer of grilled zucchini across the bottom.

Spread a layer of the herbed ricotta mixture over the zucchini.

Add another layer of grilled zucchini.

Repeat until you’ve used all the ingredients.

Try to finish with a layer of zucchini.

7. Add the Cheese

Sprinkle mozzarella, feta, and Parmesan over the top.

You don’t need a huge amount.

The goal is to add a light golden, cheesy finish while allowing the zucchini and ricotta to remain the stars.

8. Bake

Preheat your oven to 375°F (190°C).

Bake the lasagna uncovered for approximately 25–30 minutes, or until hot and bubbling around the edges.

If you want a more golden top, place it under the broiler for 1–2 minutes at the end.

Watch it closely because the cheese can brown very quickly.

9. Let It Rest

This is another step worth waiting for.

Remove the lasagna from the oven and let it rest for approximately 10–15 minutes.

This gives the layers time to settle and makes slicing much easier.

10. Garnish and Serve

Finish with fresh basil or parsley.

Add a little extra lemon zest if you love bright citrus flavor.

Serve warm.

My Best Tips

Don’t Skip Grilling the Zucchini

Grilling adds a smoky, slightly charred flavor that you simply don’t get from raw zucchini.

It also helps remove some of the vegetable’s excess moisture.

Don’t Make the Zucchini Too Thin

Very thin zucchini can become fragile and difficult to layer.

Aim for slices around ⅛–¼ inch thick.

Drain the Zucchini

This is probably the most important tip.

Zucchini naturally contains lots of water.

Allowing the grilled slices to drain before assembling helps prevent a watery lasagna.

Use Whole-Milk Ricotta

Whole-milk ricotta creates a much richer, creamier filling.

Low-fat ricotta can work, but the texture won’t be quite as luxurious.

Don’t Over-Salt

Feta brings plenty of salty flavor.

Taste the ricotta mixture before adding additional salt.

Let It Rest

I know it’s tempting to cut into it immediately.

Don’t.

Give the lasagna at least 10 minutes to rest.

The layers will firm up and you’ll get much prettier slices.

Can I Use Yellow Squash?

Absolutely.

Yellow summer squash works beautifully alongside zucchini.

You can use half zucchini and half yellow squash for a colorful variation.

Can I Use Eggplant?

Yes.

Thinly sliced grilled eggplant is a fantastic addition.

You can replace some of the zucchini with eggplant or create alternating layers.

Can I Add Tomatoes?

Definitely.

Fresh tomatoes pair beautifully with the lemon, feta, and herbs.

However, tomatoes also add moisture, so use them sparingly.

Cherry tomatoes that have been roasted or lightly drained are a particularly good option.

Can I Add Spinach?

Yes.

Wilt fresh spinach, squeeze out as much moisture as possible, chop it, and mix it into the ricotta filling.

Frozen spinach works too—just make sure it’s thoroughly squeezed dry.

Can I Add Mushrooms?

Absolutely.

Thinly sliced mushrooms can be sautéed before adding them to the layers.

Cook them until their moisture has evaporated.

Can I Add Meat?

Yes.

If you’re not keeping the recipe vegetarian, you can add:

• Grilled chicken
• Ground beef
• Italian sausage
• Shredded chicken
• Turkey

Cook the meat completely before layering it into the lasagna.

Can I Add Marinara Sauce?

You can, although this recipe is intentionally designed around the creamy lemon-herb filling rather than a traditional tomato sauce.

If you’d like a tomato version, add a thin layer of marinara between some of the zucchini layers.

Don’t use too much or the lasagna can become watery.

Can I Make It Without Mozzarella?

Absolutely.

The mozzarella is mainly for the golden topping.

You can use:

• Parmesan
• Pecorino Romano
• Provolone
• Gruyère
• Extra feta

Or simply leave it off and use feta and Parmesan.

Can I Use Cottage Cheese Instead of Ricotta?

Yes.

For a lighter filling, blend cottage cheese until relatively smooth before mixing it with the herbs and feta.

The texture will be slightly different but still delicious.

Can I Make This Keto?

Yes.

The ingredients in this recipe are naturally low in carbohydrates compared with traditional pasta lasagna.

However, carbohydrate counts vary depending on the cheeses and vegetables used, so check your ingredient labels if you’re following a strict keto plan.

Is This Gluten-Free?

Yes, provided all packaged ingredients are certified gluten-free when necessary.

There are no traditional wheat-based pasta sheets in this recipe.

Can I Make It Ahead?

Absolutely.

This is a great make-ahead dish.

Assemble the lasagna, cover it, and refrigerate it for up to approximately 24 hours before baking.

Take it out of the refrigerator while the oven preheats.

You may need to add a few extra minutes to the baking time.

Can I Freeze Zucchini Lasagna?

Yes, but the texture can become softer after freezing because zucchini contains so much water.

For the best results, allow the cooked lasagna to cool completely before freezing.

Wrap tightly and freeze in an airtight freezer-safe container.

Thaw overnight in the refrigerator before reheating.

How Do I Store Leftovers?

Place leftovers in an airtight container and refrigerate for approximately 3–4 days.

How Do I Reheat It?

Reheat individual portions in the microwave or warm larger portions in a covered oven-safe dish at 350°F (175°C) until heated through.

If the top starts browning too quickly, cover loosely with foil.

What Should I Serve With Zucchini Lasagna?

This dish is satisfying on its own, but it pairs beautifully with:

• Greek salad
• Arugula salad
• Roasted vegetables
• Garlic green beans
• Grilled chicken
• Grilled fish
• Crusty bread
• Roasted potatoes

For a Mediterranean-inspired dinner, I love serving it with a simple tomato and cucumber salad.

Can I Serve This Cold?

Yes.

After chilling, the lasagna becomes firmer and can actually be sliced very neatly.

It makes a lovely cold or room-temperature lunch, especially during warm weather.

Frequently Asked Questions

Why is my zucchini lasagna watery?

The most common reason is excess moisture from the zucchini.

Grill the zucchini first, then let it drain on paper towels before assembling.

Also avoid adding too much sauce or watery vegetables.

Why are my layers sliding apart?

The zucchini may contain too much moisture or the lasagna may have been cut immediately after baking.

Let it rest for 10–15 minutes before slicing.

Can I skip grilling the zucchini?

You can, but grilling adds flavor and helps remove moisture.

If you don’t have a grill, roast or pan-sear the zucchini instead.

How thick should the zucchini slices be?

Approximately ⅛–¼ inch is ideal.

Very thin slices can fall apart, while very thick slices can make the lasagna difficult to cut.

Can I use dried herbs?

Yes.

Fresh herbs provide the brightest flavor, but dried herbs work when fresh aren’t available.

Use smaller amounts because dried herbs are more concentrated.

Can I add lemon juice directly to the ricotta?

Yes.

Lemon juice and zest are what give this recipe its fresh, bright character.

Start with a small amount and adjust to taste.

Can I make individual portions?

Absolutely.

Layer the zucchini and ricotta mixture into small ramekins or individual baking dishes.

Reduce the baking time and check them early.

Final Thoughts

This Grilled Zucchini Lasagna is one of those recipes that surprised me in the best possible way.

I expected it to be a lighter substitute for traditional lasagna.

What I didn’t expect was how delicious it would be completely on its own.

The grilled zucchini brings a little smoky flavor.

The ricotta makes everything creamy.

The feta adds those wonderful salty bites.

And the lemon and fresh herbs keep the whole dish bright instead of heavy.

It’s the kind of meal that feels comforting while still tasting fresh.

I especially love making it when zucchini is everywhere and I’m looking for something beyond zucchini bread, stir-fries, or simple roasted vegetables.

It’s also beautiful enough to serve when friends come over.

I usually put the baking dish right in the middle of the table, add a big green salad, and let everyone help themselves.

And somehow, every time I make it, someone asks for the recipe.

That’s always a good sign.

So if you have a few zucchini waiting in your kitchen, don’t just grill them and call it dinner.

Turn them into layers.

Add creamy ricotta.

Bring in the feta, herbs, and lemon.

Bake until everything is warm and golden.

It’s fresh, creamy, smoky, cheesy, and full of Mediterranean flavor—a vegetable lasagna that feels just as comforting as the classic while letting zucchini take center stage. 🍋🥒🧀
