How to Make Grilled Zucchini Lasagna

STEP 1. Preheat the oven. Set the oven to 350°F (180°C) and lightly grease a deep baking dish.

STEP 2. Grill the zucchini. Prepare the zucchini by slicing it lengthwise and grilling it on a pan grill or BBQ until tender and slightly charred.

STEP 3. Make the white sauce. In a small pot over medium heat, melt the butter, then whisk in the flour and salt until combined. Slowly add the milk while whisking until the sauce thickens. Remove from heat and let cool.

STEP 4. Prepare the tuna mixture. In a medium bowl, combine the tuna, bread crumbs, mozzarella, egg, Parmesan cheese, olive oil, salt, black pepper, and parsley.

STEP 5. Assemble the lasagna. Drizzle a tablespoon of olive oil in the bottom of the baking dish. Layer half of the grilled zucchini, followed by a third of the tuna mixture, and pour half of the white sauce on top.

STEP 6. Repeat layering. Add another layer of grilled zucchini, another third of the tuna mixture, and the remaining half of the white sauce. Top with the remaining grilled zucchini and tuna mixture.

STEP 7. Finish with Parmesan. Sprinkle the top with freshly grated Parmesan cheese.

STEP 8. Bake the lasagna. Place in the oven and bake for about 20-25 minutes until golden and bubbling. Let it sit for 5 minutes before serving. Enjoy!

Pro Tips

Using a mandoline slicer can help achieve consistent thickness for the zucchini, ensuring they grill evenly. Opt for firm zucchini to prevent excess moisture in the dish. If you want a richer flavor, consider adding spices like Italian seasoning or garlic powder to the tuna mixture. Letting the baked lasagna rest allows the flavors to meld perfectly and makes for easier slicing. If you prefer a nice browning on top, switch to broil for the last few minutes of cooking—just keep an eye on it to avoid burning. For an even healthier twist, try substituting the mozzarella with a low-fat cheese option without sacrificing cheesiness.

Common Mistakes to Avoid

A common pitfall is overcrowding the baking dish, which can lead to uneven cooking. Ensure your layers are arranged neatly while allowing room for heat circulation. Another mistake is using overcooked zucchini; they should be grilled until just tender to maintain their shape and texture in the lasagna. Avoid using too much filling—if the layers are too thick, the dish may become soggy. Additionally, letting the lasagna sit out for too long after baking can make it watery; giving it a short resting time will help the layers hold together better. Lastly, don’t forget to adjust your seasoning—taste as you go, particularly with the white sauce, to ensure a flavorful dish.

Variations

• Substitute the tuna with shredded chicken for a different protein.
• Use ricotta cheese in place of or alongside the mozzarella for a richer filling.
• Add spinach or kale for extra nutrients and color.
• Create a vegetarian version by omitting tuna and incorporating more vegetables.
• Use different types of cheese such as feta or goat cheese for unique flavors.

Serving Ideas

Pair this delightful lasagna with a side salad for a refreshing contrast of flavors and textures. Garlic bread can be a delicious accompaniment, perfect for sopping up any extra sauce. For a complete meal, serve it alongside roasted vegetables, adding an earthy note to round out the dish. You could also enjoy it with a simple homemade vinaigrette if you prefer a lighter pairing. A glass of sparkling water or non-alcoholic spritzer will complement the rich flavors without overwhelming the palette.

Meal Prep & Storage

This recipe is a fantastic option for meal prep, as it can be made ahead of time and stored in the refrigerator for a few days. Simply assemble the lasagna but wait until you’re ready to eat to bake it, which helps retain its freshness. For longer storage, freeze individual portions in airtight containers. When ready to enjoy, thaw overnight in the refrigerator before baking. To reheat, place portions in the microwave or back in the oven until heated through. Drizzle with a little olive oil if needed to refresh the texture before serving.
