Ingredients

Scale

  • 2 medium zucchinis (about 2 lbs), sliced into ½-inch rounds

  • 1 tbsp olive oil

  • 1 small onion, diced

  • 2 garlic cloves, minced

  • 1 lb lean ground beef

  • 2 tsp Italian seasoning

  • ½ tsp kosher salt

  • ½ tsp black pepper

  • 1 can (28 oz) diced tomatoes, drained

  • 2 cups shredded mozzarella cheese

Instructions

  1. Prep Zucchini: Place zucchini rounds in a colander, sprinkle with salt, and toss to coat. Let sit for 15 minutes to draw out moisture. Rinse and pat dry.

  2. Cook Beef: Heat olive oil in a large skillet over medium-high heat. Add onion and cook 2 minutes until soft. Stir in garlic and ground beef, breaking it up as it cooks, until browned—about 5 minutes.

  3. Add Flavor: Stir in tomatoes, Italian seasoning, salt, and pepper. Remove from heat.

  4. Assemble: Preheat oven to 350°F (175°C). In an 8×8-inch baking dish, layer half the beef mixture, half the zucchini, and half the mozzarella. Repeat layers.

  5. Bake: Bake 20–25 minutes until cheese is melted and lightly golden. Let rest for 10 minutes before serving.

Notes

  • Don’t skip salting the zucchini! It removes excess water and prevents a soggy casserole.

  • Use freshly shredded mozzarella for the best melt and flavor.

  • Add a pinch of crushed red pepper for a little heat.
