Step 1 – Prep the Zucchini:
Slice zucchini into thin strips (~1/8" thick).
Lay them on paper towels, sprinkle with salt, and let sit 15–20 minutes to release moisture. Pat dry.
Step 2 – Make the Meat Sauce:
In a skillet, heat olive oil over medium heat. Add onion and garlic, sauté until soft.
Add ground beef/sausage. Cook until browned; drain fat.
Stir in marinara and Italian seasoning. Simmer for 5–10 minutes.
Step 3 – Mix Ricotta Layer:
In a bowl, mix ricotta, egg, salt, and a little Parmesan until smooth.
Step 4 – Assemble Lasagna:
Preheat oven to 375°F (190°C).
In a greased 9x9” or 9x13” dish, layer:
A spoonful of sauce
A layer of zucchini slices
Spoonfuls of ricotta mixture
Sprinkle mozzarella
Repeat layers, ending with meat sauce and remaining cheese on top.
Step 5 – Bake:
Bake uncovered for 35–40 minutes until bubbly and golden.
Optional: Broil the last 2–3 minutes to brown the top.
Let rest 10–15 minutes before slicing (this helps it hold together!).
