  • 1 lb ground beef: Choose lean or regular depending on your preference; it’s the meaty foundation of this casserole.
  • 2 zucchinis, sliced: Fresh zucchinis add moisture, subtle sweetness, and a beautiful green contrast.
  • 1 onion, diced: Adds a layer of sweetness and depth when sautéed with the beef.
  • 1 can (14 oz) diced tomatoes: Brings juiciness and a slight acidity to balance the dish.
  • 1 cup mozzarella or cheddar cheese: Melts beautifully to create a bubbly, golden crust.

  • 1 tsp Italian seasoning: A perfect blend of herbs to bring warmth and complexity.
  • Salt and pepper: Essential seasonings to enhance every bite.

How to Make Meaty Zucchini Casserole With Ground Beef Recipe

Step 1: Preheat and Prepare

Start by preheating your oven to 375°F (190°C). This ensures it’s hot and ready for baking once your layers are assembled, so the casserole cooks evenly and the cheese melts to perfection.

Step 2: Brown the Beef and Onions

In a large skillet over medium heat, sauté the diced onions until translucent and fragrant. Add the ground beef, garlic powder, Italian seasoning, salt, and pepper. Cook everything together until the beef is fully browned and the flavors are well combined. This step locks in the savory depth that makes this casserole truly satisfying.

Step 3: Layer the Casserole

In a casserole dish, create your layers by starting with a bed of zucchini slices. Then spoon a generous layer of the browned beef mixture over the zucchini, followed by a layer of diced tomatoes. Sprinkle some of the cheese on top. Repeat these layers until all the ingredients are used, finishing with cheese to get that glorious golden top.

Step 4: Bake to Bubbling Perfection

Place your assembled casserole into the preheated oven and bake for 20 to 25 minutes. You want to see the cheese bubbling and turning a beautiful golden brown, signaling that your meaty zucchini casserole is ready to be enjoyed.

Garnishes

Fresh herbs like chopped basil or parsley sprinkle a bright freshness that contrasts perfectly with the richness of the casserole. For a little extra zing, a dollop of sour cream or a drizzle of garlic-infused olive oil can elevate the dish beautifully.

Side Dishes

This casserole is a complete meal on its own but pairs wonderfully with a crisp green salad or a simple roasted vegetable medley. For low-carb enthusiasts, steamed asparagus or sautéed spinach amplify the nutrition without stealing the spotlight.

Creative Ways to Present

For a fun twist, serve this dish in individual ramekins for personalized portions that feel special. Alternatively, layer the casserole in a clear glass dish to showcase the colorful stripes of zucchini, beef, and cheese — making it as beautiful as it is delicious.

Make Ahead and Storage

Storing Leftovers

Leftover Meaty Zucchini Casserole With Ground Beef Recipe keeps well in an airtight container in the refrigerator for up to 3 days. Allow it to cool before storing to maintain the best texture and flavor.

Freezing

If you want to save some for later, this casserole freezes wonderfully. Wrap it tightly with foil or use freezer-safe containers and it can stay fresh for up to 2 months. Just be sure to thaw it overnight in the fridge before reheating.

Reheating

Reheat your leftovers in the oven at 350°F (175°C) until warmed through to maintain that lovely baked texture. Alternatively, microwave portions on medium power, but the oven method gives a better finish to the cheese topping.
