Ingredients You’ll Need
Fresh zucchini tomato casserole requires just 6 ingredients plus cooking spray, salt and pepper! If you would like more traditional casserole, try zucchini lasagna.
- Zucchini: I used two large green zucchinis. However, you can use yellow squash or even a combination of the two. Any variety of summer squash works well within this recipe for baked zucchini.
- Tomatoes: Grape or cherry tomatoes are my favorite for this zucchini tomato casserole. However, you could also use larger varieties like vine tomatoes or heirloom tomatoes.
- Garlic: And lots of it. This really amps up the flavor! Feel free to slightly reduce the amount if preferred.
- Herbs: I used 1 tsp dried herbs (in total, not each) to toss with the zucchini and tomato mixture, and there are plenty of options: dill, basil, oregano, Italian spice mix. Use 1 alone or a combination of several. I also use fresh herbs (parsley or fresh basil) to garnish.
- Parmesan cheese: Freshly grated will taste best.
How to Make Zucchini Tomato Bake
From prep to finish, this vegetable bake is on the table in only 30 minutes. Perfect for those lazy hazy days of summertime!
Preheat oven to 350 degrees F and spray an 8 x 8 or 9 x 11 baking dish with cooking spray.
Combine the ingredients: In a large mixing bowl, add your chopped zucchini and tomatoes, dried herbs, grated garlic, and Parmesan cheese. Stir your cheese mixture and vegetables to combine.
Transfer to prepared baking dish: Bake uncovered for 25 minutes for zucchini with slight ‘bite’, or 35 minutes if you like more tender results. I recommend checking for doneness with a fork or knife after 25 minutes.
Remove from the oven: And garnish with basil or parsley and serve hot or warm.
Substitutions and Variations
- Sliced veggies: You can slice 1/4 inch thick rounds from the vegetables rather than chunks and layer them alternating between zucchini and tomatoes, on their sides, within the baking dish. This is great for presentation!
- Spices: To add heat add a dash of red pepper flakes. Paprika (smoked or plain) and onion powder also work well with these ingredients.
- Vegetables: Yellow or green summer squash work in this recipe. Sliced onion or leeks will also pair well with the zucchini and tomato.
- Cheese: Instead of Parmesan cheese, you could use mozzarella cheese or another melty cheese like cheddar.
- Vegan: Replace the Parmesan with your favorite vegan melty cheese or just omit.
- Bread crumbs: For a crispy topping, add 1/8 cup or more of breadcrumbs near the end of baking time.
How to Serve
This zucchini tomato bake is so versatile! It pairs well with most proteins, vegetables, salads, and almost any carb side dish recipes, too! It works particularly well with Italian and Mediterranean dinners as well.
- As a meatless main: Served alongside garlic bread.
- With meat: Like Instant Pot whole chicken or air fryer lamb chops.
- With fish: Like lemon butter baked cod or grilled shrimp skewers.
- With salad recipes like Instant Pot potato salad.
- Over the grain of your choice: Such as quinoa, brown rice or couscous.
Don’t forget dessert, berry trifle is the perfect summer treat!

How to Make Ahead and Store
Make ahead: You can prepare the chopped vegetables and ingredients in the baking dish up to 2 days before baking.
Storing: Any leftover zucchini tomato casserole can be stored in an airtight container in the refrigerator for up to 5 days.
Freezing: I don’t recommend it. Both zucchini and tomatoes are moisture producing vegetables and would not hold up well to being frozen.
Expert Tips and FAQs
You sure can. Add diced cooked chicken, sausage or any cooked protein. If adding raw, I recommend to use diced boneless and skinless chicken breasts or thighs as they cook fast. If you would like to add any ground meat like ground turkey, saute it first with a few seasonings to taste.
You can chop the slices and allow them to rest on a paper towel before adding to the casserole dish. Best to use whole small tomatoes like grape tomatoes or cherry tomatoes. If they are small enough, you don’t have to cut them.
Don’t overcook it and don’t cover it while cooking! Zucchini can go from firm to mushy within minutes, so ensure you check your casserole at 25 minutes. Set a timer so it doesn’t accidentally overcook.
I haven’t tried but I’m pretty sure you can use frozen chopped zucchini. Do not thaw and try to bake casserole at 400 degrees F for 20 minutes and play it by ear after that. Frozen zucchini need to be cooked at higher temperature and faster.
