Ingredients You’ll Need

Vegetables & Dairy

• 4 large zucchini (or 5 small)

Herbs & Flavor

How to Prep the Zucchini

Zucchini is made up of about 95% water, which can make your lasagna soggy if not handled properly. Here’s how to prep it right:

• Slice zucchini lengthwise using a mandoline or peeler
• Salt slices lightly and let them sit for 15 minutes
• Blot excess moisture with paper towels
• Optional: grill or roast the slices briefly to reduce moisture further

How to Make the Meat Sauce

• In a skillet, cook the ground beef until browned
• Drain excess fat
• Add pasta sauce and simmer for 5–10 minutes
• Season with Italian herbs or chili flakes (optional)

Ricotta Cheese Mixture

• In a bowl, mix:
  • Ricotta cheese
  • Grated parmesan
  • Egg
  • Salt and pepper
• Stir until smooth and creamy

Layering the Lasagna

Now the fun part—assembly!

1. Spread a layer of pasta sauce on the bottom of your dish
2. Lay out zucchini slices (overlap slightly)
3. Spoon half the meat sauce over the zucchini
4. Spread half the ricotta mixture evenly
5. Sprinkle some mozzarella, parsley, and basil
6. Repeat the layers
7. Top with final zucchini layer and finish with mozzarella and herbs

Baking Instructions

• Preheat oven to 400°F (200°C)
• Bake for 40–45 minutes
• Broil for 2–5 minutes for a golden cheesy crust
