A flavorful layered casserole featuring zucchini, tomatoes, and onions, topped with cheesy bread crumbs. Perfect for summer gatherings or a comforting family dinner.
Ingredients
Instructions
- Combine bread crumbs, melted butter, and Parmesan cheese to make the bread crumb mixture.
- In a greased 1 1/2-quart casserole dish, layer half of the diced onion, diced tomatoes, and sliced zucchini.
- Repeat the layering with the remaining onion, tomatoes, and zucchini.
- Sprinkle with salt, pepper, and Cheddar cheese over the layered vegetables.
- Top with the prepared bread crumb mixture.
- Bake at 350°F for 30 to 40 minutes or until the casserole is tender and golden on top.
Tips & Substitutions
For a more robust flavor, consider adding garlic or herbs like basil and oregano to the vegetable layers. If you don't have Parmesan cheese, you can use any hard cheese you have on hand. To make this dish gluten-free, substitute regular bread with gluten-free bread or breadcrumbs. Additionally, using a mix of cheeses can enhance the flavor, so feel free to experiment with mozzarella or Gouda.
Serving Suggestions
This layered summer casserole is delicious on its own but pairs beautifully with a fresh garden salad or crusty bread. For a heartier meal, serve it alongside grilled chicken or fish. It also makes a wonderful side dish for gatherings, complementing other vegetarian recipes like Veggie Medley Casserole.
Storage & Reheating
Leftover casserole can be stored in an airtight container in the refrigerator for up to 3 days. To reheat, simply place it in the oven at 350°F for about 15-20 minutes until warmed through. You can also microwave individual portions for about 2-3 minutes, but the oven method will keep the topping crispy.
