How to Make Ground Beef and Zucchini Casserole

Step 1: Prepare the Vegetables

Start by washing the zucchini thoroughly and slicing them into thin rounds or half-moons to ensure they cook evenly. Dice the onion finely and mince the garlic cloves to release their aroma.

Step 2: Cook the Ground Beef

Heat olive oil in a large skillet over medium heat, then add the ground beef. Cook, breaking it apart with a spoon, until browned and fully cooked through—this should take about 7-8 minutes. Drain any excess fat to keep the casserole lighter.

Step 3: Sauté Onions and Garlic

Add diced onions to the skillet with the beef and sauté until they become translucent. Follow with minced garlic, cooking for just a minute until fragrant, being careful not to burn it.

Step 4: Combine Sauce and Seasoning

Pour in the tomato sauce and sprinkle the Italian seasoning, salt, and pepper. Stir to combine all flavors and let the mixture simmer gently for 5 minutes to thicken slightly.

Step 5: Layer the Casserole

Preheat your oven to 375°F (190°C). In a greased baking dish, layer half the zucchini slices, followed by the ground beef sauce mixture, then the remaining zucchini. Top evenly with shredded cheese.

Step 6: Bake Until Bubbly and Golden

Bake uncovered for 25-30 minutes until the cheese is melted, golden, and bubbling. Let it rest for 5 minutes before serving to help it set and make slicing easier.

Pro Tips for Making Ground Beef and Zucchini Casserole

• Drain Excess Moisture: Salt the zucchini slices lightly and let them sit to release water before layering to avoid a soggy casserole.
• Use Fresh Herbs: Adding fresh basil or parsley at the end brightens up the flavors beautifully.
• Don’t Overcook Zucchini: Keep the slices slightly firm to maintain texture after baking.
• Cheese Blend: Experiment with equal parts mozzarella and cheddar for the best melting and flavor combination.
• Even Slicing: Use a mandoline slicer for uniform zucchini pieces that cook evenly.
