How to Make Meaty Zucchini Casserole With Ground Beef Recipe

Step 1: Prepare Your Oven and Ingredients

Start by preheating your oven to 375°F, so it’s perfectly hot when you’re ready to bake. While the oven warms up, slice the zucchini, dice the onion, and mince the garlic to have everything ready for cooking.

Step 2: Brown the Ground Beef

Heat the olive oil in a large skillet over medium-high heat. Add the ground beef and cook it until it’s nicely browned on all sides, stirring occasionally. This step locks in flavor and gives your casserole that meaty depth. Once browned, drain any excess fat to avoid sogginess.

Step 3: Sauté Onion and Garlic

To the same skillet, add diced onion and minced garlic. Sauté for about 3 minutes until the onion softens and the garlic becomes fragrant. This step layers in aromatic goodness that will carry through the entire dish.

Step 4: Add Zucchini, Tomatoes, and Seasonings

Stir in the sliced zucchini and drained diced tomatoes. Sprinkle in the Italian seasoning, salt, and pepper, stirring everything until well combined. The zucchini starts to soften and absorb the flavors, while the tomatoes add a gentle acidity that brightens the mixture.

Step 5: Assemble and Bake

Transfer the mixture into a baking dish in an even layer. Sprinkle the shredded cheese evenly across the top to create a luscious melted crown. Place the dish in the oven and bake for 20 to 25 minutes, until the zucchini is tender and the cheese is bubbly and golden. Your kitchen will fill with the most wonderful scent during this time.

Garnishes

Fresh herbs like chopped parsley or basil add a pop of color and a fresh, vibrant flavor right before serving. A light drizzle of olive oil or a sprinkle of red pepper flakes can bring a subtle kick and complexity to each bite.

Side Dishes

This casserole pairs beautifully with a crisp green salad or some roasted garlic bread for soaking up any juices. If you want to keep things light and low-carb, steamed asparagus or sautéed mushrooms complement the dish perfectly without overpowering it.

Creative Ways to Present

For a fun twist, try layering this casserole in individual ramekins for personal servings or turning it into a layered bake by alternating zucchini slices and meat mixture. This can look stunning on the table and makes portioning a breeze if serving guests.

Make Ahead and Storage

Storing Leftovers

Once cooled, transfer leftovers to an airtight container and keep them refrigerated for up to 3 days. The flavors develop even more overnight, making next-day meals just as delightful.

Freezing

You can freeze this casserole for up to 2 months. Be sure to use a freezer-safe container and thaw it in the refrigerator overnight before reheating to maintain texture and flavor.

Reheating

Reheat leftovers covered in the oven at 350°F for about 15-20 minutes or until warmed through. Alternatively, microwave individual portions for a quicker option, but the oven method will best preserve the original texture and melty cheese topping.
