Baked zucchini and cheese is one of those effortless dishes that delivers big comfort with minimal prep. Every bite is a reminder of late summer days when zucchini is overflowing at the market and light dinners are most welcome. This recipe layers fresh vegetables and oozy cheese and turns a humble baking dish into a bubbly masterpiece that fits any busy weeknight or weekend potluck.
I love that this recipe makes veggies the star but never feels overly virtuous. My family always requests extra mozzarella on top and I am always happy to oblige.
Ingredients
- Zucchini: diced for tender texture and mild flavor look for firm zucchinis with shiny skin
- Green bell pepper: diced for sweetness and color choose ones that feel heavy and show no wrinkles
- Onion: chopped for aromatic depth yellow or white onion both work well
- Grape tomatoes: halved for juicy bursts and color choose the ripest for the sweetest punch
- Olive oil: coats vegetables for roasting use a good quality extra virgin oil for better flavor
- Garlic powder: gives easy savory flavor opt for granulated garlic powder for even coating
- Italian seasoning: brings warmth and classic herb flavor check the blend for fresh aroma
- Salt: brings all the flavors together sea salt or kosher salt work best
- Freshly cracked black pepper: brighten and sharpens every bite use freshly ground for the boldest flavor
- Grated mozzarella cheese: melts beautifully and adds creaminess shred your own for the best melting
- Chopped fresh parsley: brings fresh color and a little brightness grab a bunch with crisp leaves
- Crushed red chili pepper flakes (optional): for a gentle kick start with a pinch and adjust to taste
Instructions
- Prep the Oven:
- Set your oven to 375 degrees Fahrenheit or 190 degrees Celsius early so it heats fully before baking. This ensures even cooking and a bubbly cheesy top.
- Mix the Vegetables:
- Add diced zucchini green bell pepper chopped onion and halved grape tomatoes to a large mixing bowl. Pour in olive oil garlic powder Italian seasoning salt and black pepper. Toss really thoroughly so every piece is slicked with flavor and oil this helps everything roast up tender and tasty.
- Blend with Cheese:
- Fold in half of the grated mozzarella cheese. The cheese binds the mix and starts the melty texture early. Make sure the cheese is well distributed for perfect bites every time.
- Fill the Baking Dish:
- Spread the vegetable and cheese mixture evenly in a 9 by 13 inch baking dish. Leveling out the mixture helps everything cook through and keeps the cheese layer even.
- First Bake:
- Place the dish in your preheated oven and bake for 20 minutes. The zucchini will soften and the tomato juices will start to bubble. Use this time to tidy up the kitchen.
- Add More Cheese:
- Take the pan out carefully and sprinkle the remaining mozzarella cheese all over the top. This layer browns up and creates an irresistible crust.
- Finish Baking:
- Return the dish to the oven for another 10 minutes. You want the cheese on top to melt completely and start turning light golden around the edges.
- Garnish and Serve:
- Let the pan cool for a minute. Sprinkle parsley and a pinch of crushed red chili pepper flakes over the top. Serve generous scoops while the cheese is still gooey.

My favorite part is always the sweet burst of grape tomatoes against the rich mozzarella. This casserole reminds me of summers spent in my grandmother’s kitchen pulling parsley straight from the garden for the finishing touch.
Storage tips
Cool the casserole completely before covering tightly and storing in the refrigerator. It keeps for up to four days without losing texture. To reheat cover with foil and bake in a moderate oven until hot or warm microwave portions as needed.
Ingredient substitutions
If you do not have mozzarella try provolone cheddar or Monterey Jack for a different flavor. Swap grape tomatoes for cherry or even diced Roma tomatoes if that is what you find. Yellow squash or red bell pepper will fill in for zucchini or green pepper with a gentle twist.
Serving suggestions
Serve straight from the pan with crusty bread and fresh salad for a sunny meal. It works just as well as a brunch side or a comforting vegetarian main. If you have meat lovers at the table a side of rotisserie chicken or grilled sausage is a nice match.
Cultural and historical context
Vegetable gratins and baked cheese dishes have deep roots in Mediterranean kitchens. Combining summer squash and cheese in a simple casserole shows off the best produce at its peak while making the most of leftovers. Every farm house has its own take and this recipe keeps that easy tradition alive.
Seasonal Adaptations
Use eggplant or yellow squash when zucchini is out of season. Fresh basil or oregano can be swapped for the Italian seasoning. Try adding cooked corn off the cob for a little sweetness and crunch.
Success Stories
Last summer I brought this dish to a neighborhood potluck and it vanished faster than anything else on the table. Even picky eaters went back for seconds. It is one of those foolproof recipes that never fails to get compliments.
Freezer Meal Conversion
To freeze assemble the vegetable and cheese mixture in the baking dish but hold off on the second cheese layer. Wrap tightly and freeze up to two months. Thaw overnight in the fridge then add cheese and bake as directed letting it go a few extra minutes if needed.

Baked zucchini and cheese gives simple ingredients new life. It is just right for sharing at the table or enjoying all for yourself.
