Zucchini Harvest Casserole: A Taste of Summer Comfort

There are certain dishes that, with just one bite, transport you back in time. For me, this Zucchini Casserole is one of them. I remember my grandmother making this on sweltering August afternoons, the scent of simmering vegetables mingling with the aroma of freshly cut grass drifting in through the open kitchen window. It wasn’t just food; it was a hug on a plate, a delicious testament to the abundance of our garden, and a simple reminder that sometimes, the most satisfying meals are the ones made with love and the freshest ingredients. This recipe, a gentle adaptation of one I found in a cherished La Leche League cookbook, has become a staple in my own kitchen, a comforting echo of those sun-drenched days.

Ingredients

This vibrant casserole is a celebration of summer’s bounty, layering fresh vegetables with a creamy, herb-infused ricotta mixture and a comforting cheesy topping.

For the Casserole:

• 4 cups zucchini, thinly sliced
• 2/3 cup onion, thinly sliced
• 2 cups tomatoes, sliced thin
• 1/2 cup green pepper, chopped
• 1 cup tomato sauce
• 1 1/2 cups cheddar cheese, grated

For the Ricotta Mixture:

• 1 cup ricotta cheese
• 2 teaspoons oregano
• 1 teaspoon dried chives
• 1 teaspoon garlic powder
• 1/2 teaspoon salt
• 1 dash pepper

For the Toppings:

• 1/4 cup grated parmesan cheese
• 1/4 cup breadcrumbs

Equipment Needed

• A 3-quart casserole dish (or similarly sized baking dish)
• A medium bowl for mixing the ricotta
• A baking sheet (optional, to catch any drips)
• Measuring cups and spoons
• A knife and cutting board for preparing vegetables

Instructions

Crafting this delightful zucchini casserole is a straightforward process, layering simple ingredients to create a harmonious and flavorful dish. Follow these steps carefully for a truly satisfying result.

1. Begin by greasing your 3-quart casserole dish. This will ensure that your casserole doesn’t stick and makes for easy serving.
2. In a separate medium bowl, combine the ricotta cheese, oregano, dried chives, garlic powder, salt, and pepper. Mix these ingredients thoroughly until well incorporated. This herbaceous ricotta mixture will add a wonderful creamy depth to the casserole. Set aside this mixture.
3. Now, it’s time to start layering. In your prepared casserole dish, add half of each of the following ingredients, in the order listed: the thinly sliced zucchini, the thinly sliced onion, the thinly sliced tomatoes, the chopped green pepper, the tomato sauce, the grated cheddar cheese, and finally, dollops or an even spread of the prepared ricotta mixture.
4. Repeat these layers using the remaining half of each ingredient: zucchini, onion, tomatoes, green pepper, tomato sauce, cheddar cheese, and ricotta mixture. Aim for an even distribution of each component to ensure consistent flavor throughout the casserole.
5. For the finishing touch, sprinkle the grated parmesan cheese evenly over the top layer, followed by the breadcrumbs. This will create a lovely golden-brown, slightly crisp topping.
6. Cover the casserole dish tightly with foil.
7. Bake in a preheated oven at 350°F (175°C) for 25 minutes. This initial covered baking time allows the vegetables to soften and meld together beautifully without drying out.
8. After 25 minutes, carefully remove the foil from the casserole.
9. Continue baking, uncovered, for an additional 10 minutes, or until the topping is golden brown and the casserole is bubbly. This uncovered period is crucial for achieving that desirable crisp topping.

Expert Tips & Tricks

• Uniform Slicing: For the best texture and even cooking, try to slice your zucchini and tomatoes to a consistent thickness. About ¼ inch is ideal. If your zucchini are very large, you might want to halve or quarter them lengthwise before slicing.
• Draining Zucchini: If you find your zucchini releases a lot of water, especially if they are very ripe, you can lightly salt the sliced zucchini and let them sit in a colander for about 15-20 minutes before patting them dry with paper towels. This is an optional step but can help prevent a watery casserole.
• Cheese Variations: While cheddar and parmesan are classic, feel free to experiment with other melting cheeses like Monterey Jack, Gruyère, or a blend of Italian cheeses for a different flavor profile.
• Herb Power: If you have fresh herbs on hand, feel free to substitute them for the dried ones. Use about three times the amount of fresh herbs (e.g., 1 tablespoon of fresh oregano).
• Make-Ahead Magic: You can assemble the casserole a day in advance, up to step 5. Cover it tightly and refrigerate. When ready to bake, let it sit at room temperature for about 30 minutes before proceeding with the baking instructions, and you may need to add a few extra minutes to the covered baking time to ensure it’s heated through.

Serving & Storage Suggestions

This Zucchini Casserole is a wonderfully versatile dish, perfect as a hearty vegetarian main course or a delightful side dish. It pairs beautifully with a crisp green salad and crusty bread. For a more substantial meal, consider serving it alongside grilled chicken or fish.

To serve, allow the casserole to rest for about 5-10 minutes after it comes out of the oven. This allows the layers to set slightly, making it easier to slice and serve.

Leftovers can be stored in an airtight container in the refrigerator for up to 3-4 days. To reheat, gently warm portions in the microwave or in a moderate oven (around 325°F/160°C) until heated through. If the topping seems a little soft after refrigeration, you can briefly broil it for a minute or two to crisp it up again.
