How to Make Meaty Zucchini Casserole with Ground Beef Recipe

Step 1: Prepare and Sauté

Start by preheating your oven to 375°F (190°C) and greasing a 9×13-inch baking dish. Next, heat olive oil in a large skillet over medium heat. Add the ground beef and cook, stirring occasionally, until it’s nicely browned. This step is crucial because browning the beef adds a depth of flavor that makes the casserole irresistible. Once browned, drain any excess grease, then toss in the diced onion.

Step 2: Build Flavor

Cook the onion with the beef for about 3 to 4 minutes until it softens and becomes slightly translucent. Then add the minced garlic, cooking just for 30 seconds to release its fragrance without burning it. These aromatics create the lovely savory base that carries the entire dish.

Step 3: Combine Zucchini and Sauce

Stir in the zucchini pieces, marinara or tomato sauce, Italian seasoning, salt, and pepper. Allow everything to simmer gently for approximately 5 minutes. This softens the zucchini just enough and lets it soak up the tomato sauce’s wonderful flavor — crucial to the luscious texture that defines this casserole.

Step 4: Assemble and Bake

Transfer the beautiful meat and zucchini mixture into the prepared baking dish. Evenly sprinkle the shredded mozzarella and cheddar (or Parmesan) cheeses on top to guarantee a golden, bubbly crust. Bake uncovered for 25 to 30 minutes until the casserole is bubbling and the cheese has melted to a dreamy golden finish.

Step 5: Garnish and Serve

Once out of the oven, add a sprinkle of fresh parsley or basil to brighten the look and flavor. Your Meaty Zucchini Casserole with Ground Beef Recipe is now ready to warm up your table and your heart.

Garnishes

A little fresh herb like parsley or basil goes a long way in lifting the flavors and adding a pleasant visual pop. You can also sprinkle some crushed red pepper flakes or extra grated cheese for personalized flair.

Side Dishes

This casserole stands beautifully on its own, but pairing it with a crisp green salad or garlic bread can complement the richness perfectly. A light arugula salad with lemon vinaigrette offers a zesty contrast that balances the meaty flavors superbly.

Creative Ways to Present

For a fun twist, serve the casserole in individual ramekins or mini cast-iron skillets. This brings an inviting rustic charm to your table and makes portion control a breeze, perfect for family dinners or casual gatherings.
