How to Make Zucchini Ground Beef Casserole

Step 1: Prepare the ingredients

Wash and slice the zucchini into thin rounds or half-moons; finely chop the onion and mince the garlic. This prep ensures everything cooks evenly and melds well together in the casserole.

Step 2: Cook the ground beef mixture

In a large skillet over medium heat, brown the ground beef with onions and garlic until fully cooked and fragrant. Drain any excess fat, then stir in tomato sauce, herbs, salt, and pepper to create a flavorful filling.

Step 3: Layer the casserole

Grease a baking dish and start with a layer of zucchini slices at the bottom. Spread half of the beef mixture evenly over the zucchini, then add another zucchini layer and the remaining beef mixture on top. Finish with a generous sprinkling of shredded cheese.

Step 4: Bake until bubbly and golden

Bake the casserole in a preheated oven at 375°F (190°C) for about 25-30 minutes until the cheese is melted, bubbly, and lightly browned on top, signaling it’s ready to enjoy.

Pro Tips for Making Zucchini Ground Beef Casserole

• Drain excess moisture: Salt sliced zucchini lightly and let it sit before assembling to reduce watery casserole.
• Use quality beef: Opt for fresh ground beef with appropriate fat content for richer flavor.
• Layer strategically: Arrange zucchini and meat layers evenly for balanced bites.
• Cheese choice matters: Use a melty cheese blend with good stretch for the ultimate comforting texture.
• Let it rest: Allow the casserole to cool for 5 minutes after baking to set and make slicing easier.

How to Serve Zucchini Ground Beef Casserole

Garnishes

Sprinkle freshly chopped parsley or basil over the top for a pop of color and fresh herb flavor that complements the rich casserole beautifully.

Side Dishes

This casserole pairs wonderfully with crisp green salads, crusty bread, or roasted vegetables to round out the meal and add varied textures.

Creative Ways to Present

For entertaining, serve individual portions in ramekins or decorative dishes, and offer toppings like grated parmesan or hot sauce on the side for guests to customize.

Make Ahead and Storage

Storing Leftovers

Place any leftover casserole in an airtight container and refrigerate for up to four days, making it easy to enjoy quick meals later in the week.

Freezing

Freeze uncooked casserole before baking by wrapping tightly in foil and plastic wrap; thaw in the refrigerator overnight before baking as usual.

Reheating

Reheat leftovers in the oven at 350°F (175°C) for 15-20 minutes or until warmed through to preserve texture and flavor better than microwaving.
