Main Ingredients

  • 4 medium zucchini, sliced Use medium zucchinis for even slices.
  • 1 lb ground turkey or beef Choose turkey for a leaner option or beef for richer flavor.
  • 1 medium onion, chopped Adds sweetness and texture.
  • 1 medium bell pepper, chopped Optional, can substitute with mushrooms.
  • 2 cups marinara sauce Choose a no sugar added variety for less sweetness.
  • 1 tsp Italian seasoning Alternatively, use dried oregano and basil.
  • 2 cups shredded mozzarella cheese For a richer topping, blend in other cheeses.

Instructions
 

Preparation

  • Preheat your oven to 375°F (190°C) and spray a baking dish with non-stick cooking spray.
  • Slice the zucchinis thinly for even cooking.

Cooking

  • In a skillet over medium heat, brown the ground turkey or beef for 5–7 minutes, breaking it into small pieces.
  • Drain excess fat if necessary.
  • Add Italian seasoning, chopped onion, and bell pepper, and sauté for 3–4 minutes until softened.
  • Layer half of the zucchini slices in the baking dish, followed by half of the meat mixture, and half of the marinara sauce. Repeat the layers.
  • Top with shredded mozzarella cheese, cover with foil, and bake for 25 minutes.
  • Remove foil and bake for an additional 15 minutes until cheese is golden and bubbly.
  • Let the casserole rest for 5–10 minutes before serving.

Notes

Slice zucchini evenly for uniform cooking. Drain fat from meat to avoid a watery casserole. Let rest before cutting for better serving.
