Step‑by‑Step Instructions for Ground Beef Zucchini Casserole
  1. Preheat your oven to 375°F (190°C).
  2. Heat 2 tablespoons of olive oil in a large skillet over medium heat. Add 1 diced onion and 2 minced garlic cloves, sautéing for 3-4 minutes until the onion is translucent.
  3. Add 1 pound of ground beef to the skillet, breaking it apart. Cook for 5-7 minutes until fully browned, draining excess grease if needed.
  4. Stir in 1 tablespoon of Italian seasoning, 1 teaspoon of kosher salt, and 1/2 teaspoon of black pepper. Mix well and cook for 1-2 minutes.
  5. Incorporate a can of drained diced tomatoes into the beef mixture, stirring well and cooking for an additional 2 minutes.
  6. Spread half of the sliced zucchini as the first layer in a greased casserole dish. Follow with half of the beef mixture and 1 cup of shredded mozzarella cheese. Repeat the layers, topping with remaining mozzarella cheese.
  7. Cover the casserole dish with aluminum foil and bake for 25 minutes. Remove the foil and bake for an additional 15 minutes until the cheese is bubbly and golden.
  8. Let the casserole cool for about 5 minutes before serving.

Notes

Avoid excess moisture by slicing zucchini thinly and letting it drain on paper towels before layering in the casserole. Lean ground turkey or chicken can be used for a lighter version.
