How to make baked zucchini and cheese
Nothing easier! Cheesy zucchini casserole is simple to make, with only a handful of ingredients and steps before popping it in the oven. In a baking dish, combine diced zucchini, bell pepper, tomatoes, onion, spices, herbs, half the cheese, and olive oil. Bake in the oven at 375ºF (190ºC) until almost tender, sprinkle the remaining cheese on top. Then finish baking the zucchini and cheese for another 10 minutes in the oven. Done!








Directions
1. To make the baked zucchini and cheese: Preheat your oven to 375ºF (190ºC).
2. In a baking dish, combine diced zucchini, bell pepper, chopped onions, grape tomatoes, Italian seasoning, garlic powder, and half the shredded mozzarella. Season with salt, fresh ground black pepper, and drizzle with olive oil. Stir together until the veggies are coated with cheese and the herbs are well-distributed.
3. Bake in the oven, uncovered for about 20 minutes, or slightly longer. Pierce a piece of zucchini with a fork to be sure it’s mostly tender.
4. When the zucchini is nearly cooked through, remove the baking from the oven and sprinkle over the remaining 1/2 cup of grated mozzarella. Put the dish back in the oven and bake 10 minutes longer, or until the cheese is melted and nicely browned and the zucchini is fully cooked. Sprinkle with fresh parsley and red chili pepper flakes. Serve the baked zucchini and cheese immediately. Enjoy! ❤️

How to avoid baked zucchini from getting soggy?
Zucchini contains a lot of water, so when it bakes it can release a lot of excess water making your baked zucchini come out watery. If you have extra time, you can do this to prevent zucchini from getting soggy: Lightly salt your diced zucchini on all sides, then place it on a thick layer of paper towels. Let the diced zucchini sit here for 15 minutes, then flip them over and let them rest for another 15 minutes. You’ll see how much water comes out of the zucchini and is absorbed by the paper towel! Do not add any salt to the recipe afterward.
Alternately, you can saute the zucchini in a skillet with a little olive oil before tossing it with the other ingredients.
How to keep the baked zucchini and cheese leftovers
This cheesy zucchini bake keeps well in the fridge for 2 days in an airtight container. Reheat in the oven or microwave. We do not recommend freezing because zucchini will still hold a lot of water, even after it’s cooked, and will release much of that water when it thaws.

I made this today, with a couple changes. I didn't have cherry tomatoes, so I diced a large tomato and used it instead. I also used shredded cheddar cheese (about a cup) in addition to the mozzarella. It was delicious!
