Preheat Oven: Start by preheating your oven to 375°F (190°C) to get it nice and warm for your casserole. This ensures even cooking for that delicious, golden top.

Sauté Onions: In a skillet over medium heat, add a drizzle of olive oil and sauté the chopped onion until it’s soft and translucent. This should take about 3-4 minutes, then add the minced garlic and sauté for an additional 30 seconds until fragrant.

Add Zucchini & Sauce: Stir in the sliced zucchini, tomato sauce, and Italian seasoning. Let it simmer for about 10 minutes, allowing the flavors to meld beautifully and the zucchini to soften.

Layer Casserole: In a greased baking dish, layer half of the meat mixture followed by half of the shredded cheddar cheese. Repeat the layers, finishing with the cheese on top for that mouthwatering, cheesy finish.
