The Classic Baked Zucchini Casserole Recipe
This recipe provides a solid foundation for creating a delicious and comforting zucchini casserole. Feel free to adjust the ingredients and seasonings to your liking.
Ingredients:
* 4 medium zucchini (about 2 pounds), thinly sliced
* 1 medium onion, chopped
* 2 cloves garlic, minced
* 2 tablespoons olive oil
* 1 (14.5 ounce) can diced tomatoes, drained
* 1/2 cup grated Parmesan cheese
* 1/2 cup shredded mozzarella cheese
* 1/4 cup chopped fresh basil
* 1 teaspoon dried oregano
* 1/2 teaspoon salt
* 1/4 teaspoon black pepper
* 1 cup bread crumbs (panko or Italian-seasoned)
* 2 tablespoons melted butter
Equipment:
* Large skillet
* 9×13 inch baking dish
* Mixing bowls
* Cutting board
* Knife
* Measuring cups and spoons
Instructions:
1. **Prepare the Zucchini:** Wash and thinly slice the zucchini. You can use a mandoline for consistent slicing, but a sharp knife works just as well. If the zucchini is particularly watery, you can lightly salt the slices and let them sit in a colander for about 30 minutes to draw out excess moisture. Pat them dry with paper towels before proceeding.
2. **Sauté the Vegetables:** Heat the olive oil in a large skillet over medium heat. Add the chopped onion and cook until softened, about 5-7 minutes. Add the minced garlic and cook for another minute until fragrant. Be careful not to burn the garlic.
3. **Combine Ingredients:** Add the sliced zucchini and drained diced tomatoes to the skillet. Cook, stirring occasionally, until the zucchini is slightly tender, about 8-10 minutes. Season with salt, pepper, and oregano. Remove from heat.
4. **Prepare the Cheese Mixture:** In a mixing bowl, combine the Parmesan cheese, mozzarella cheese, and chopped fresh basil.
5. **Assemble the Casserole:** Preheat your oven to 375°F (190°C). Grease a 9×13 inch baking dish.
6. **Layer the Ingredients:** Spread a thin layer of the zucchini mixture in the bottom of the baking dish. Sprinkle with a layer of the cheese mixture. Repeat the layers until all the zucchini mixture and cheese mixture are used, ending with a layer of cheese on top.
7. **Prepare the Breadcrumb Topping:** In a small bowl, combine the bread crumbs and melted butter. Mix well until the bread crumbs are evenly coated.
8. **Add the Topping:** Sprinkle the breadcrumb mixture evenly over the top of the casserole.
9. **Bake the Casserole:** Bake in the preheated oven for 25-30 minutes, or until the top is golden brown and the cheese is melted and bubbly. The internal temperature should reach 165°F (74°C).
10. **Let it Rest:** Remove the casserole from the oven and let it rest for 5-10 minutes before serving. This allows the flavors to meld and the casserole to set slightly.
Tips for Success:
* **Control Moisture:** Zucchini can be quite watery. Salting and draining the zucchini slices beforehand helps to prevent a soggy casserole. Cooking the zucchini mixture in a skillet also allows some of the moisture to evaporate.
* **Don’t Overcook:** Overcooked zucchini can become mushy. Cook it until it’s just tender, not completely soft.
* **Use Fresh Herbs:** Fresh basil adds a bright and vibrant flavor to the casserole. If you don’t have fresh basil, you can use dried basil, but use about half the amount.
* **Adjust Seasoning:** Taste the zucchini mixture before assembling the casserole and adjust the seasoning as needed. You may want to add more salt, pepper, or oregano.
* **Broil for Extra Browning:** If the top of the casserole isn’t as brown as you’d like, you can broil it for a minute or two at the end of the baking time. Watch it carefully to prevent burning.
* **Resting is Key:** Letting the casserole rest after baking allows the flavors to meld and the casserole to set slightly, making it easier to serve.
Zucchini Casserole Variations: Adding Flavor and Texture
The basic zucchini casserole recipe is a blank canvas for your culinary creativity. Here are some variations to inspire you:

Making Zucchini Casserole Ahead of Time
Zucchini casserole is a great make-ahead dish. You can assemble the casserole up to 24 hours in advance and store it in the refrigerator, covered. When you’re ready to bake it, add the breadcrumb topping and bake as directed. You may need to add a few extra minutes to the baking time if the casserole is cold.
Alternatively, you can bake the casserole completely and then reheat it later. Store the baked casserole in the refrigerator, covered, for up to 3 days. To reheat, cover the casserole with foil and bake in a preheated oven at 350°F (175°C) for 20-30 minutes, or until heated through. You can also reheat individual portions in the microwave.
Serving Suggestions
Baked zucchini casserole is a versatile dish that can be served as a main course or a side dish. Here are some serving suggestions:
* **As a Main Course:** Serve with a side salad, crusty bread, or grilled chicken or fish.
* **As a Side Dish:** Serve alongside roasted meats, grilled vegetables, or pasta dishes.
* **Breakfast or Brunch:** Serve with eggs, bacon, or sausage for a hearty breakfast or brunch.
* **Potlucks and Gatherings:** Zucchini casserole is a great dish to bring to potlucks and family gatherings. It’s easy to transport and can be served hot or at room temperature.
Tips for Storing Leftovers
Store leftover zucchini casserole in an airtight container in the refrigerator for up to 3 days. Reheat in the oven, microwave, or skillet. The casserole may become slightly softer after being refrigerated, but it will still be delicious.
Troubleshooting
* **Soggy Casserole:** This is usually caused by excess moisture in the zucchini. Make sure to salt and drain the zucchini slices beforehand and cook the zucchini mixture in a skillet to evaporate some of the moisture.
* **Dry Casserole:** This can be caused by overcooking or not using enough liquid. Add a can of tomato sauce or cream of soup to the zucchini mixture to add moisture.
* **Bland Casserole:** This can be caused by not using enough seasoning. Taste the zucchini mixture before assembling the casserole and adjust the seasoning as needed. You can also add fresh herbs or spices to enhance the flavor.
* **Burnt Topping:** This can be caused by baking the casserole at too high of a temperature or for too long. Cover the casserole with foil during the last few minutes of baking to prevent the topping from burning.
* **Unevenly Cooked Casserole:** Make sure to spread the zucchini mixture evenly in the baking dish to ensure that the casserole cooks evenly.
