🔪 Step-by-Step Instructions

Step 1: Prepare the Zucchini

1. Preheat oven to 400°F (200°C).

2. Slice zucchini lengthwise into thin strips (about ⅛-inch thick). A mandoline works best for even slices.

3. Lay slices on paper towels and sprinkle with salt. Let sit for 15–20 minutes to draw out excess moisture.

4. Pat dry thoroughly.

5. Lightly brush with olive oil and bake on a lined sheet for 10–15 minutes until slightly softened.

6. Remove and lower oven temperature to 375°F (190°C).

💡 Tip: Removing moisture prevents watery lasagna.

Step 2: Make the Meat Sauce

1. Heat a large skillet over medium heat.

2. Add ground beef and cook until browned, breaking apart as it cooks.

3. Add onion and cook until softened (about 3–4 minutes).

4. Stir in garlic and cook 30 seconds until fragrant.

5. Add marinara sauce, tomato paste, and all seasonings.

6. Simmer for 10–15 minutes until thickened.

7. Taste and adjust seasoning if needed.

Step 3: Prepare Ricotta Mixture

In a bowl, mix together:

• Ricotta cheese

• Egg

• Parmesan

• Parsley

• Salt & pepper

Stir until smooth and creamy.

Step 4: Assemble the Lasagna

In a 9×13-inch baking dish:

1. Spread a thin layer of meat sauce on the bottom.

2. Add a layer of zucchini slices (slightly overlapping).

3. Spread ricotta mixture evenly over zucchini.

4. Add a layer of meat sauce.

5. Sprinkle mozzarella cheese.

Repeat layers 2–3 times, finishing with meat sauce and mozzarella on top.
Sprinkle extra Parmesan on the final layer.

Step 5: Bake

1. Cover with foil and bake at 375°F (190°C) for 30 minutes.

2. Remove foil and bake an additional 15–20 minutes until bubbly and golden.

3. Let rest for at least 15–20 minutes before slicing (important for clean layers!).
