Ingredient Checklist

For this easy zucchini casserole, the main ingredients you need include zucchinis, fresh tomatoes and garlic, fresh parsley and green onions, as well as lemon juice, olive oil, white vinegar or grape vinegar, and some spices.

Each of these ingredients is incredibly easy to find and even substitute if need be. You can have a look at our variations section to see how you can substitute these ingredients.

Because zucchinis are the hero ingredient for this dish, make sure to pick the freshest and most ripe ones you can find.

How To Make

This is an incredibly easy recipe to make and once it's inside the oven, you can simply sit back and relax – or make one of our delicious accompaniments!

First, make the tomato mixture. Combine the pureed tomatoes, garlic, parsley, spices, green onions, olive oil, vinegar, and lemon juice. Make sure you mix the ingredients well so they are equally distributed.

Second, thinly slice the zucchinis and place them in a baking dish. 

Then pour the tomato mixture over them and mix them well. Each slice should be well coated in the red sauce. Use your hand to help coat them without breaking the slices.

Next, layer the slices and bake. Transfer the slices to your prepared baking dish. The key is to prevent the zucchini layers from becoming too thick.

Bake the dish for roughly 45 minutes or until the top gets a nice golden brown color.

Variations

• You can substitute the parsley with fresh coriander/cilantro leaves.
• You can easily substitute the green onions with either white or red onions. You can even try using shallots or salad onions.
• To create a chunkier texture, try using sliced tomatoes instead besides tomato puree.
• And of course, last but certainly not least, you can change the spices with ease. We prefer using a type of Mexican chili spice or paprika, but you can also use a wide variety of spice mixes.   

Tips

• Slice the zucchini thinly. You can use a mandoline slicer to do this. 
• Use the freshest and tastiest tomatoes you can find. They give the best flavor you need in this zucchini tomato casserole. If you can’t find good tomatoes, then we would suggest you add 1-2 tablespoons of tomato paste.
• For the vinegar, it is also very important to use a good quality flavorful kind. For this courgette recipe, we prefer using grape vinegar. Apple cider vinegar is a fantastic choice too and has a good balance of sweetness and tang. Here is a great article describing the differences between types of vinegar. You can experiment with some of them and see which you prefer. 
• If you don’t like the aroma of vinegar or don’t have it on hand, use more lemon juice instead. 
• Make sure 4-5 slices of zucchini overlap in the baking dish, not more than this. So make sure your baking pan is not too small for all the slices.

Serving Suggestions

You can serve this casserole either hot or at room temperature. We always pair it with some yogurt or cacik dip. If you are following a vegan diet, use your favorite plant-based yogurt. 

If you are planning to have it for a lunch or dinner menu, you can also make some orzo rice pilaf or bulgur pilaf to serve on the side.

How To Store

You can store this zucchini tomato bake either before or after it has been cooked. To store it before, combine and layer all of the ingredients inside the baking dish. Simply place a layer of plastic wrap on the surface of the zucchinis and then wrap the entire dish.

The same method applies for an already baked zucchini casserole; simply place a layer or wrap on the surface, then wrap the entire dish.

Store the zucchini and tomato casserole inside the refrigerator for up to 5 days, cooked or uncooked.

If you want to store any leftover casserole, transfer them to an airtight container and keep them inside the refrigerator for roughly 4-5 days.
