How to Make Zucchini Casserole with Ground Beef
Preparing the Zucchini
Start by preheating your oven to 375°F (190°C). Grease an 8-inch baking dish with 1 tablespoon of olive oil. Slice the zucchini lengthwise into thin strips, then place them on paper towels. Sprinkle with sea salt to draw out moisture and let them rest for 15 minutes.
Cooking the Ground Beef and Marinara Sauce
While the zucchini is resting, prepare the meat sauce. In a saucepan over medium-high heat, sauté garlic, ground beef, 1 cup of fresh basil, 1 teaspoon of sea salt, and black pepper until the meat is browned, which should take about 10 minutes. Next, add diced tomatoes and marinara sauce to the mixture and let it simmer on low heat for 5 minutes.
Assembling the Zucchini Casserole
Now, it’s time to assemble your casserole! In a mixing bowl, combine ricotta cheese, egg, and black pepper until smooth. In the greased baking dish, layer the zucchini slices, then spread the meat sauce, followed by the ricotta mixture, and sprinkle with black olives. Add mozzarella cheese on top. Repeat these layers until all ingredients are used.
Baking and Serving Instructions

Cover the final layer with the remaining sauce mixture, then sprinkle with Parmesan cheese and additional olive slices. Bake for 30-40 minutes, or until the top is golden brown. Let it cool for 5 minutes before serving, and garnish with fresh basil for an extra burst of flavor.
