Baked zucchini loaded with gooey cheese is honestly a cozy dish that catches everyone off guard with how much they love it. The veggies get all soft in the oven, then mozzarella turns bubbly and gooey on top. It’s an easy favorite for summer hauls but honestly I throw it together anytime I spot good looking zucchini. I make this for busy weeknights and even the stubborn eaters usually ask for more.
Honestly the first time I put this together my kid swore up and down she would not touch zucchini. But after one bite where the cheese was all gooey and golden, she had another scoop right away, no questions asked.
Tasty Ingredients
- Zucchini: Pick zucchini that feels firm and looks shiny for the best bite. This is the main event.
- Green bell pepper: Crunchy, just a little sweet. Use ones that feel firm and look fresh.
- Onion: White or yellow both work well. Go for fresh to keep the flavor bright.
- Grape tomatoes: Juicy and just the right hit of tang. Grab them if they look lively and shiny.
- Olive oil: Gives that silky, golden touch when baking. Splash in your best extra virgin if you have it.
- Garlic powder: Simple way to get even, quick flavor in every bite.
- Italian seasoning: Mix of oregano, basil, thyme and more. It’s what adds the classic Italian touch. Use a good blend if you can.
- Salt: Wakes up all those veggie flavors.
- Freshly cracked black pepper: Bright flavor and some heat—cracked fresh is tastier.
- Mozzarella cheese: Full fat melts the best, and grating it yourself makes everything creamier. Grab pre-shredded when you’re in a rush.
- Fresh parsley: Chopped up for a blast of fresh color before serving.
- Crushed red chili pepper flakes: Sprinkle on for some spicy kick, but only if you like a little heat.
Easy How-To Steps
- Garnish and Enjoy:
- After pulling the pan out, let it sit for a couple of minutes. Sprinkle fresh parsley and chili flakes on top. Scoop it up while warm and enjoy those cheese pulls.
- Finish with Cheese:
- Pull out the tray carefully and cover everything with the rest of the mozzarella. Don’t rush—this step is the secret to that melty top layer.
- Final Bake:
- Pop the dish back in for another 10 minutes. When the cheese is bubbly and tinged with brown on the edges, you’re good.
- Bake Part One:
- Get the pan into your hot oven. Bake for about 20 minutes so the zucchini softens up but still holds its shape. This gets the flavors mingling.
- Layer in the Dish:
- Dump everything from the bowl into a 9 x 13 baking dish. Spread it evenly so things roast the same and cheese later melts nicely over all the veggies.
- Add First Cheese:
- Toss in half your grated mozzarella right into the veggie bowl. Mix so cheesy bits land all through the veggies for melty goodness in every bite.
- Season Everything:
- Drizzle oil over your chopped veggies, then sprinkle in garlic powder, Italian spice blend, salt, and pepper. Give it all a solid stir so every piece is slicked and seasoned.
- Chop the Veggies:
- Grab a big bowl and toss in bite-sized zucchini and bell pepper, diced onion, and halved grape tomatoes. Work on your chopping board and throw everything together.
- Get the Oven Ready:
- Set your oven to 375°F (190°C). Make sure your rack is in the center so everything cooks consistently.

Mozzarella is definitely the showstopper here. I’ve experimented with cheddar but nothing melts and stretches like mozzarella does—can’t beat that. It usually ends in everyone scrambling for that last gooey bite at family dinners.
Storing Leftovers
Stash leftovers in a sealed container in the fridge and this baked zucchini will be tasty for up to three days. For best results, reheat in the oven or toaster oven so the cheese stays gooey and you avoid sogginess. If you’re in a hurry, a quick blast in the microwave works fine but the cheese is nicest when warmed gently.
Swapping Ingredients
No zucchini? Yellow squash works perfectly. Out of green peppers? Red or orange give it extra sweetness. Short on mozzarella? Try Monterey Jack or mild provolone, but leave super hard cheeses like parmesan out—melty is the goal here.
Ways To Eat This
I like serving this up next to grilled chicken or fish for a solid meal. It’s also great tossed with pasta or piled on some crusty bread to soak up all that cheesy goodness. Brings something special to summer get-togethers or potlucks too.

The Backstory
Bakes like this have roots all over the Mediterranean, where there’s loads of summer squash to go around. Tossing in cheese and herbs turns a bunch of vegetables into a cozy meal that brings everyone together. It’s that comfy, nostalgic casserole vibe mixed with the punchy taste of fresh produce.
