Ingredients

Scale

Zucchini Preparation

  • 2 medium zucchini, sliced (about 2 pounds)
  • 1/2 tsp kosher salt (for drawing out moisture)

Meat Mixture

  • 1 tbsp olive oil
  • 1 small onion, diced
  • 2 garlic cloves, minced
  • 1 pound lean ground beef
  • 2 tsp Italian seasoning
  • 1/2 tsp kosher salt
  • 1/2 tsp black pepper
  • 1 28 ounce can diced tomatoes, drained

Topping

  • 2 cups shredded mozzarella cheese

Instructions

  1. Prepare the zucchini: Slice the zucchini into 1/2″ rounds. Place the slices in a sieve or colander over the sink or a bowl. Sprinkle with 1/2 teaspoon kosher salt and toss to coat evenly. This will help draw out excess moisture from the zucchini.
  2. Drain the zucchini: Allow the salted zucchini to sit for 15 minutes. This resting period enables the salt to pull out excess water. Afterward, rinse the zucchini well under cold water to remove the excess salt, then pat dry thoroughly with paper towels to prevent a soggy casserole.
  3. Sauté aromatics and brown beef: Heat 1 tablespoon of olive oil in a large skillet over medium-high heat. Add the diced onion and cook until they start to soften, about 2 minutes. Add minced garlic and then the ground beef. Break up the beef with a spoon and cook, stirring frequently, until fully browned and no longer pink, approximately 5 minutes.
  4. Add seasonings and tomatoes: Stir in the drained diced tomatoes, 2 teaspoons Italian seasoning, 1/2 teaspoon kosher salt, and 1/2 teaspoon black pepper into the cooked beef mixture. Mix well and remove from heat.
  5. Preheat oven and assemble casserole: Preheat your oven to 350°F (175°C). In an 8×8 inch baking dish, spread half of the ground beef mixture evenly. Layer half of the prepared zucchini slices over the meat, then sprinkle half of the shredded mozzarella cheese on top.
  6. Repeat layers: Repeat the layering process with the remaining ground beef mixture, zucchini slices, and mozzarella cheese to build a two-layer casserole.
  7. Bake the casserole: Bake in the preheated oven for 20 to 25 minutes, until the cheese is melted and begins to brown slightly on top.
  8. Rest before serving: Remove the casserole from the oven and let it rest for 10 minutes to allow flavors to meld and the dish to set for easier serving.

Notes

  • Pressing and salting the zucchini helps reduce water content, preventing a watery casserole.
  • You can substitute mozzarella with a blend of mozzarella and Parmesan for extra depth.
  • Use lean ground beef to reduce fat and grease in the dish.
  • To make this recipe gluten-free, ensure your canned tomatoes contain no added gluten ingredients.
  • This casserole can be reheated in the oven or microwave for leftovers.
