How to Make Ground Beef Zucchini Casserole
Prepare Your Ingredients: Start by preheating your oven to 375°F (190°C). Chop your zucchini into half-moon slices and dice your onion. Get ready for some savory fun.
Sauté the Vegetables: In a large skillet over medium heat, add olive oil. Toss in the diced onion and minced garlic until fragrant and translucent. This should take about 3-5 minutes.
Brown the Ground Beef: Add ground beef to the skillet. Cook until browned, breaking it apart with a spatula until no pink remains. It’ll smell amazing, trust me!
Add Zucchini and Tomatoes: Stir in sliced zucchini and crushed tomatoes along with Italian seasoning. Cook until zucchini softens slightly—around 5-7 minutes—before removing from heat.
Create Layers in Casserole Dish: In a greased baking dish, layer half of the beef mixture at the bottom. Sprinkle half of the mozzarella cheese on top before repeating these layers with remaining ingredients.
