Cheesy Zucchini and Ground Beef Casserole Tips, FAQ & printable recipe

Tips for success

To add extra depth to the flavor, consider incorporating finely minced garlic or a pinch of dried Italian herbs into the ground beef while it browns in the skillet. These additions should be added during the last minute of cooking to prevent the garlic from burning, which can lead to a bitter taste in the final dish.

If you prefer a crispier texture, you can broil the casserole for 1 to 2 minutes at the very end of the baking time. Watch the oven closely during this process, as the cheese can go from perfectly golden to burnt in a matter of seconds. Use this technique sparingly to achieve the desired level of browning without compromising the tender zucchini.

Variations

• Spicy Beef and Zucchini: Add a tablespoon of taco seasoning or diced jalapeños to the ground beef while browning for a spicy kick that complements the cheese.
• Vegetarian Zucchini Casserole: Replace the ground beef with a mixture of sautéed mushrooms and diced bell peppers to create a delicious, meat-free version of this classic dish.

Storage and make-ahead

Fridge

Keep refrigerated in an airtight container for up to 3 days.

Freezer

Freeze in a freezer-safe container for up to 1 month; thaw overnight in the fridge before reheating.

Reheat

Reheat individual portions in the microwave or in a 350°F oven until heated through.

Store any leftover casserole in an airtight container to maintain freshness and prevent the absorption of other odors from the refrigerator.

If the dish was transferred to a smaller container while still warm, ensure it has cooled to room temperature, but do not leave it out for longer than two hours. Properly stored, the leftovers will retain their quality for up to three days.

This recipe is an excellent candidate for making ahead. You can assemble the entire casserole, cover it tightly with plastic wrap or foil, and refrigerate it for up to 24 hours before baking.

When ready to cook, remove it from the refrigerator and let it sit on the counter for 20 minutes to take the chill off before placing it into the preheated oven.

Serving ideas

Serve this casserole hot, straight from the baking dish, using a metal spatula to lift portions onto individual plates. The dish pairs beautifully with a side of crusty bread or a simple green salad dressed with a light vinaigrette.

Because the casserole is rich, these lighter sides provide a necessary balance that rounds out the meal effectively for a satisfying dining experience.

If desired, garnish each portion with fresh herbs like chopped parsley or basil to add a pop of color and a touch of brightness. These herbs should be added just before serving to maintain their vibrancy and fresh flavor.

For those who enjoy a bit of heat, a light drizzle of hot sauce or a sprinkle of red pepper flakes can be added to individual portions according to personal preference.

Prep 15 minCook 40 minRest 10 minTotal 1 h 5 minServes 6

Ingredients

• 1 lb ground beef
• 3 large zucchini, sliced into thin rounds
• 2 cups shredded cheddar cheese
• 1 tsp salt and pepper, to taste

Instructions

1. Heat a large skillet over medium-high heat. Add the ground beef and cook, breaking it apart with a spatula, until browned and no longer pink. Season with salt and pepper to taste. Ensure the internal temperature reaches at least 160°F (71°C) to be fully cooked.
2. Preheat the oven to 375°F (190°C). In a 9x13 inch baking dish, spread a layer of the cooked ground beef evenly over the bottom. Arrange the sliced zucchini in a shingled pattern on top of the beef. Sprinkle the shredded cheese generously over the zucchini layer.
3. Place the baking dish into the preheated oven and bake for 25 to 30 minutes, or until the cheese is bubbly and golden brown and the zucchini is tender. Remove from the oven and allow the casserole to rest for 10 minutes before serving to ensure the layers set properly.
