Ingredients

• 2 pounds Zucchini (trimmed, sliced into 1/4‑inch strips)
• 2 tablespoons Olive Oil (for brushing zucchini and sautéing)
• 2 teaspoons Salt (kosher or table salt)
• 1 teaspoon Black Pepper (freshly ground)
• 1 cup Fresh Basil Leaves (loosely packed, divided for sauce, cheese mixture, and garnish)
• 0.5 large Onion (finely chopped)
• 3 cloves Garlic Cloves (minced)
• 1 pound Ground Beef (80% lean)
• 24 ounces Pasta Sauce (store‑bought marinara, low‑water content)
• 15 ounces Ricotta Cheese (full‑fat, room temperature)
• 3 cups Mozzarella Cheese (shredded)
• 1 cup Parmesan Cheese (freshly grated)
• 1 each Egg (large, room temperature)
• 12 pieces Toothpicks (to keep foil off the top while baking)

Instructions

1. Slice the Zucchini

   Trim the ends off the zucchini. Using a mandolin (wear a safety glove), slice the zucchini into 1/4‑inch thick strips. Discard or set aside the end pieces.

   Time: PT10M

2. Season and Grill Zucchini

   Arrange the slices on a baking sheet, spray lightly with cooking spray or brush with olive oil, then season both sides with salt and pepper. Heat a cast‑iron grill pan over medium‑high heat and grill each slice for about 2 minutes per side until lightly charred but still crisp.

   Time: PT12M

   Temperature: Medium‑high

3. Prep Herbs and Aromatics

   Stack the basil leaves, roll into a log and thinly slice. Finely chop the onion and mince the garlic cloves.

   Time: PT5M

4. Make the Meat Sauce

   In a large Dutch oven over medium‑high heat, add 1 tbsp olive oil and brown the ground beef, breaking it up with a spatula, about 5 minutes. Drain excess fat, leaving roughly 2 tbsp oil. Add the chopped onion and sauté 5 minutes until softened. Stir in the minced garlic and cook 1 minute until fragrant. Add the pasta sauce, half of the sliced basil, 1 tsp salt and ½ tsp black pepper. Bring to a light boil, then lower to a simmer, partially cover, and cook 10 minutes.

   Time: PT20M

   Temperature: Medium‑high to low simmer

5. Prepare the Cheese Sauce

   In a large mixing bowl combine the ricotta cheese, 1 cup shredded mozzarella, the egg, 1 cup grated Parmesan, the remaining chopped basil, and ½ tsp salt. Stir until smooth.

   Time: PT5M

6. Preheat the Oven

   Preheat the oven to 375°F (190°C).

   Time: PT10M

   Temperature: 375°F

7. Assemble the Lasagna

   In a 9x13‑inch casserole dish, spread ½ cup of meat sauce on the bottom. Lay a single layer of grilled zucchini strips. Spoon 1/3 of the meat sauce over the zucchini, then sprinkle 1 cup shredded mozzarella. Drop half of the cheese sauce on top and spread gently. Repeat the layering: zucchini, 1/3 meat sauce, 1 cup mozzarella, remaining cheese sauce. Finish with a final layer of zucchini, the remaining 1/3 meat sauce, and the last cup of mozzarella. Insert toothpicks around the perimeter to keep foil from touching the cheese.

   Time: PT15M

8. Bake Covered

   Cover the dish tightly with aluminum foil and bake in the center of the preheated oven for 40‑45 minutes.

   Time: PT45M

   Temperature: 375°F

9. Broil for a Golden Top

   Remove the foil and toothpicks. Switch the oven to broil and cook for 3‑4 minutes, watching closely, until the cheese is bubbling and golden.

   Time: PT4M

   Temperature: Broil

10. Rest and Serve

    Allow the lasagna to rest for 15 minutes before slicing. Garnish with a few fresh basil leaves and cut with a serrated knife.

    Time: PT15M
