Instructions

Preheat the oven to 375°Fahrenheit (190°Celsius) and gather all ingredients, including ground beef, zucchini, cheeses, egg, sauce, and seasonings, so everything is ready for smooth assembly.
Slice the zucchini thinly, sprinkle lightly with salt, and let sit for 10 minutes to release moisture. Pat completely dry to prevent a watery lasagna.
Brown the ground beef over medium heat until fully cooked, then drain excess grease. Stir in marinara and Italian seasoning and simmer briefly to combine flavors.
Mix ricotta, egg, salt, and pepper until smooth and creamy. Keep nearby so it’s ready for layering.
Lightly oil the baking dish, then layer zucchini, ricotta mixture, meat sauce, and mozzarella. Repeat layers and finish with mozzarella and Parmesan on top.
Cover with foil and bake for 25 minutes, then uncover and bake another 15 minutes until bubbly and golden. Rest for 10 minutes before slicing so the layers set.

Notes

Squeeze: Always squeeze out excess moisture before adding cheese. This prevents a watery casserole and keeps the bake perfectly cheesy.
Use Sharp Cheeses: Choose sharp cheddar cheese and parmesan cheese for bold flavor. Mixing cheeses also adds depth and makes the casserole richer.
Season Well: Don’t skimp on salt, pepper, and minced garlic. Proper seasoning brings out the natural flavor of the zucchini and enhances the cheesy taste.
Layer Strategically: Layer zucchini and cheese evenly in the baking dish. This ensures every bite has the right balance of vegetables and melted cheese.
